Description

Technical Field

[0001] The present invention belongs to the technical field of cooking stoves, and particularly relates to a heat storage cooking stove and a barbecue stove using the same. Background Art

[0002] Cooking stoves are very diverse in design. They can be divided into gas fuel type, liquid fuel type and solid fuel type, or there are differences between upright type and split type. Or they can also be divided into general outdoor type or mountain climbing type according to the application scenario. The stable heat supply of the cooking stove and the reduction of energy consumption as much as possible are the key directions to be considered in the design.

[0003] A Chinese patent discloses a hot melt coating diesel heating stove. The stove base body with a closed bottom is in a cylindrical shape. An air supply pipe is provided on the side wall of the stove base body. A burner cylinder body is provided inside the stove base body. A vertical oil passage hole is opened on the burner cylinder body. In the present invention, through the provided oil passage hole, diesel is preheated to more than 200 °C before entering the burner cylinder body for combustion. The preheated diesel is fully atomized through the atomization holes. The air supply airflow forms a cyclone airflow inside the burner cylinder body through the air inlet hole. The high-speed rotation of the cyclone airflow enables the atomized diesel to be fully mixed with air for combustion. The preheated diesel can be burned more quickly and fully to a higher temperature. The combustion temperature can exceed 800 °C, realizing the rapid heating of the hot melt coating on site.

[0004] If the above cooking stove is adopted, using diesel as the raw material for direct heating, the heating function of the cooking stove is limited to the pot body located above the burner. Since the heat absorption efficiency of the pot body for the combustion heat energy of the burner is relatively low, a large amount of heat energy is carried away by the exhaust gas after combustion, and there are sensible heat and latent heat that are not reasonably utilized, resulting in great energy waste. Summary of the Invention

Specific embodiments

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0035] Embodiment 1

[0036] As Figures 1-9 shown, a structural diagram of a heat storage stove provided by the present invention includes: a furnace body 1 with a top for placing cookware to be heated, a heating component 2 arranged inside the furnace body 1, an energy storage component 3 installed inside the furnace body 1 and capable of charging and discharging heat, and a smoke exhaust pipe group 4 connected to the furnace body 1 and used to control the emission of flue gas inside the furnace body 1.

[0037] In practical application of this embodiment, by setting the furnace body 1, it is convenient to place the cookware to be heated. The heating component 2 arranged inside the furnace body 1 can continuously generate heat and supply energy inside the furnace body 1, which not only increases the temperature inside the furnace body 1 but also facilitates heating the cookware. By setting the smoke exhaust pipe group 4, it is convenient to control the retention or discharge of high-temperature flue gas from the furnace body 1. Thus, in cooperation with the energy storage component 3, the excess heat in the flue gas is transferred to the energy storage component 3, thereby reducing the heat loss caused by the direct discharge of flue gas. The energy storage component 3 can charge heat when the heating component 2 supplies heat, store the thermal energy in the furnace, effectively store the waste heat inside the furnace body 1, and then release heat to the inside of the furnace body 1, which can play a role in heat equalization, prevent local overheating inside the furnace body 1, change the traditional convective heat transfer to radiative heat transfer, and improve the heat exchange efficiency of the stove.

[0038] Furthermore, as Figure 2As shown, the energy storage component 3 includes: a first energy storage unit 31 disposed inside the furnace body 1 and a second energy storage unit 32 disposed outside the first energy storage unit 31 and spaced apart from it by a certain distance.

[0039] Specifically, both the first energy storage unit 31 and the second energy storage unit 32 include a plurality of molten salt members 33 arranged at equal intervals along the circumferential direction. The molten salt member 33 includes a hollow shell and molten salt filled inside the shell.

[0040] It can be known that by setting the energy storage component 3 as the first energy storage unit 31 and the second energy storage unit 32, it is convenient to store energy at multiple positions inside the furnace body 1, and fully contact with the flue gas inside the furnace body 1, thereby improving the energy storage effect.

[0041] It should be noted that molten salt is a molten body formed after salts are melted. Due to the characteristics of high boiling point, low viscosity, low vapor pressure, and high volumetric heat, it is an excellent heat transfer and energy storage medium; in the actual operation of this embodiment, since molten salt heat storage belongs to phase change heat storage, molten salt heat storage mainly relies on heat absorption or heat release during the phase change to complete the heat storage or heat release process. Thus, it can change from solid state to liquid state and absorb heat during heating to carry out the heat storage process, or change from liquid state to solid state and release solidification heat to carry out the heat release process.

[0042] It should be noted that the first energy storage unit 31 and the second energy storage unit 32 can be fixedly installed inside the furnace body 1, or can be movably installed according to needs to achieve different energy storage states. This embodiment does not make specific limitations here.

[0043] Exemplarily, the shell of the molten salt member 33 in this embodiment can adopt a rod shape or a cube, as long as it can store molten salt and carry out heat storage and heat release. The shape of the shell is not a restrictive regulation; the molten salt can adopt crystals such as chloride salts or nitrate salts, as long as it can carry out phase change and achieve energy charging and discharging. This embodiment does not make specific limitations here.

[0044] Further, as Figure 2 and Figures 7-9 shown, the heating component 2 includes: a first burner head 21 disposed inside the first energy storage unit 31, a second burner head 22 disposed between the first energy storage unit 31 and the second energy storage unit 32, a fuel pipe 23 connected to the first burner head 21 and the second burner head 22, and an energy supply member 24 communicated with the fuel pipe 23.

[0045] It can be known that the heating component 2 can be used to heat the interior of the furnace body 1. By arranging the first burner head 21 inside the first energy storage unit 31 and the second burner head 22 between the first energy storage unit 31 and the second energy storage unit 32, it is ensured that each molten salt piece 33 in the outer ring and the inner ring can be heated or cooled evenly. Since the first burner head 21 and the second burner head 22 are both arranged inside the furnace body 1, and the first energy storage unit 31 and the second energy storage unit 32 are arranged on the side, the traditional convective heat transfer is changed to radiative heat transfer, increasing the heat exchange efficiency.

[0046] Furthermore, as Figures 4-6 shown, the exhaust pipe group 4 includes: a smoke pipe 41 connected to the furnace body 1, a first pressure valve 42 arranged inside the smoke pipe 41 and close to the connection end of the smoke pipe 41 and the furnace body 1, a water tank 43, a one-way valve 44 installed inside the smoke pipe 41, a temperature sensor arranged inside the furnace body 1 and signal-connected to the first pressure valve 42, and a serpentine pipe 45 connected to the end of the smoke pipe 41 far from the furnace body 1 and accommodated inside the water tank 43.

[0047] It can be known that by arranging the exhaust pipe group 4, it is convenient to control and discharge the smoke generated after burning fuel inside the furnace body 1. Thus, the first pressure valve 42 and the temperature sensor can be used to adjust the flue gas outflow volume inside the furnace in real time. By arranging the one-way valve 44, the backflow of flue gas is avoided. The serpentine pipe 45 and the water tank 43 can be used to exchange heat between the discharged high-temperature flue gas and the water in the water tank 43, so that the waste heat in the flue gas is stored in the water tank 43, realizing the waste heat recovery of the high-temperature flue gas. The water in the water tank 43 can be used for other purposes, further improving the utilization rate of fuel.

[0048] In actual operation of this embodiment, when the temperature sensor senses that the temperature inside the furnace body 1 is high, the first pressure valve 42 can control the high-temperature flue gas to stay inside the furnace for a longer time, transferring more heat to the stove, improving the thermal efficiency; when the temperature inside the furnace body 1 is low, the first pressure valve 42 can control the flue gas to be discharged from the furnace body, and the flue gas is introduced into the water tank 43 through the exhaust pipe 41 for heat exchange.

[0049] Exemplarily, the energy supply component 24 can be a gas tank, and the fuel inside it can be liquefied gas or natural gas. The fuel pipe 23 can be a high-temperature resistant gas pipe, thus realizing the gas guiding function.

[0050] Embodiment 2

[0051] As Figures 1-9As shown, on the basis of Embodiment 1, the furnace body 1 includes: a lower furnace barrel 12 with a hollow interior and an opening at the top, a lower partition 13 fixedly arranged on the inner wall of the lower furnace barrel 12, a partition net 15 fixedly arranged on the top of the lower partition 13 and with an outer diameter smaller than the inner diameter of the lower furnace barrel 12, an upper furnace barrel 11 slidably installed inside the opening and sleeved outside the partition net 15, and an upper partition 14 fixedly installed inside the top of the partition net 15. A notch is provided at the top of the upper furnace barrel 11. A plurality of through holes are formed in the side surface of the partition net 15. The partition net 15 is further provided with a buckle for buckling and fixing the upper furnace barrel 11. An accommodation cavity 16 is formed between the bottom side wall and the inner bottom surface of the lower partition 13 and the lower furnace barrel 12.

[0052] It can be known that by setting the furnace body 1 as the upper furnace barrel 11 and the lower furnace barrel 12, slidingly installing the upper furnace barrel 11 inside the opening of the lower furnace barrel 12, and fixing the upper furnace barrel 11 through the buckle on the partition net 15, the structure of the furnace body 1 can be adjusted as needed to meet different heating requirements. By arranging the partition net 15, it is convenient to uniformly transfer heat to the inside of the lower furnace barrel 12 through the plurality of through holes formed in its side surface, so that food can be baked between the lower furnace barrel 12 and the partition net 15, and cooking utensils can be installed on the top of the upper furnace barrel 11 to heat food, thus meeting different needs.

[0053] Specifically, the upper and lower two-layer setting can be used to separately heat the cooking utensils on the top by the upper furnace barrel 11 when needed, or move the upper furnace barrel 11 into the lower furnace barrel 12, so that the upper furnace barrel 11 heats the cooking utensils on the top, and the internal spaces of the upper furnace barrel 11 and the lower furnace barrel 12 are used for baking.

[0054] Furthermore, as Figures 8-9 shown, one ends of the first energy storage unit 31 and the second energy storage unit 32 are arranged inside the upper furnace barrel 11, and the other ends both penetrate through the upper partition 14 and are located inside the lower furnace barrel 12. An inner disk 34 is fixedly installed at one end of the first energy storage unit 31 located in the lower furnace barrel 12. An outer disk 35 is fixedly installed at one end of the second energy storage unit 32 located in the lower furnace barrel 12. The inner disk 34 is connected with a first support member 36 that slidably penetrates through the lower partition 13. The outer disk 35 is connected with a second support member 37 that slidably penetrates through the lower partition 13. And first lifting members 38 and second lifting members 39 are respectively connected to one ends of the first support member 36 and the second support member 37 located in the accommodation cavity 16.

[0055] It can be known that by using the inner plate 34, the outer plate 35, the first support member 36 and the second support member 37, it is convenient to realize the height adjustment of the first energy storage unit 31 and the second energy storage unit 32 driven by the first lifting member 38 and the second lifting member 39. Thus, the first energy storage unit 31 and the second energy storage unit 32 can be respectively placed in the upper furnace barrel 11 as needed, or respectively placed inside the upper furnace barrel 11 and the lower furnace barrel 12, so as to realize the simultaneous operation or hierarchical operation of the upper furnace barrel 11 and the lower furnace barrel 12 to meet different cooking needs.

[0056] It should be noted that the upper partition plate 14 and the lower partition plate 13 can be heat insulation plates, and circular holes through which the first energy storage unit 31 and the second energy storage unit 32 pass are provided in the middle, and they are made of heat insulation materials to ensure that the accommodating cavity 16 is not affected.

[0057] Exemplarily, the first support member 36 and the second support member 37 can be respectively a first lifting rod and a second lifting rod, and their shapes can be cylindrical or cubic; the first lifting member 38 and the second lifting member 39 can be a worm gear lift or a hydraulic rod, and the first lifting rod and the second lifting rod can be made of high-temperature resistant materials, and specific limitations are not made in this embodiment.

[0058] Embodiment 3

[0059] As Figure 4 and Figure 8 shown, on the basis of Embodiment 1 and Embodiment 2, the fuel pipe 23 is fixedly installed above the lower partition plate 13 and the top end passes through the middle position of the upper partition plate 14, the first burner 21 is fixed on the top of the fuel pipe 23, the second burner 22 is fixed on the top of the upper partition plate 14, and a third burner 25 connected to the fuel pipe 23 and located between the first support member 36 and the second support member 37 is fixedly installed on the top of the lower partition plate 13.

[0060] It can be known that by arranging the first burner 21 on the top of the fuel pipe 23 and inside the first energy storage unit 31, and the second burner 22 on the upper partition plate 14, it is convenient to uniformly heat the first energy storage unit 31 and the second energy storage unit 32. By using the third burner 25 arranged on the lower partition plate 13, the lower furnace barrel 12 can be heated when needed to adjust the inside of the lower furnace barrel 12 to a suitable temperature.

[0061] In actual application of this embodiment, the first burner 21 and the second burner 22 are on the same horizontal plane, which can meet the boiling and cooking requirements for cooking utensils above the upper furnace barrel 11. Its fuel pipe 23 leads to the lower furnace barrel 12 from the first burner 21, and the heat of the first burner 21 can be adjusted according to needs. The third burner 25 is used to heat the molten salt part 33 with insufficient collected waste heat, and the heat can be adjusted to facilitate baking food.

[0062] Further, as Figures 5-8 shown, the energy supply member 24 and the water tank 43 are both fixedly installed inside the accommodation cavity 16. One end of the smoke pipe 41 is connected to the outer wall of the upper furnace barrel 11, and the other end passes through the lower partition 13 and is connected to the water tank 43 inside the accommodation cavity 16. A smoke passage opening 46 opposite to the partition net 15 is formed on one side of the smoke pipe 41, and a second pressure valve 47 is installed at the smoke passage opening 46.

[0063] It can be known that by arranging the energy supply member 24 and the water tank 43 inside the accommodation cavity 16, they are separated from the heating area above. By providing the smoke passage opening 46, the flue gas beside the partition net 15 can be further collected, which is beneficial to realizing smokeless heating.

[0064] During the actual operation of this embodiment, the internal space of the accommodation cavity 16 is sufficient. In addition to the space for placing the water tank 43 and the gas tank, a storage space can also be set up to store the necessary components for operating this barbecue oven. The division of its internal space is not a restrictive regulation of this embodiment.

Its hot end is in contact with the furnace body 1, and the cold end is placed in the air for natural heat dissipation to generate electric energy, which is stored in the battery inside the accommodation cavity 16. The electric energy is used for the exhaust pipe group 4 and the lifting. When the upper furnace barrel 11 needs to be cooled and the lower furnace barrel 12 is not working, the molten salt member 33 of the upper furnace barrel 11 can be lowered to the lower furnace barrel 12, and its heat energy is used for thermoelectric power generation.
