Description

Technical Field

[0001] The present invention relates to the technical field of kitchen equipment, and in particular to a combustion chamber and a heat flow channel using the combustion chamber. Background Art

[0002] The shallow plate ration heater uses liquid fuel or gas fuel as energy, and is mainly used for heating shallow plate rations. It also takes into account various food processing methods such as boiling, stewing, steaming, and frying. It can process more food at the same time, as well as packaged food such as shallow plate rations. It has high efficiency and also has a power generation function, good energy-saving and consumption-reducing effect, high reliability in use, and long service life. It is particularly suitable for occasions where a large number of people dine outdoors at the same time. It can adapt to harsh environments, especially occasions in the wild that need to quickly, efficiently, safely and reliably solve food and water problems. It can adapt well to harsh environments such as plateaus, deserts, low temperatures or high temperatures, and ensure the safe, efficient and rapid heating of shallow plate rations.

[0003] In existing shallow tray ration heaters, the heat flow opening of the combustion chamber used in conjunction with the burner is usually only opened upward, which is not conducive to heat flow circulation and full utilization of heat.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The object of the present invention is to provide a combustion chamber and a heat flow channel using the same, so as to solve the technical problems existing in the prior art.

[0014] In an optional embodiment, the fire isolation plate contacts the inner cavity of the inner container on three sides, and contacts and covers the first guide plate and the second guide plate.

[0015] In an optional embodiment, the fire isolation board is in contact with the side wall of the inner container where the heat outlet is provided, and the length of the fire isolation board is smaller than the length of the bottom wall of the inner container.

[0016] The beneficial effects of the present invention are:

[0017] (1) The first outlet of the combustion chamber is provided with two first guide plates and one second guide plate upwardly on the shell of the combustion chamber body. The ends of the two first guide plates are respectively connected to one end of the second guide plate. A second outlet is formed between the front ends of the two first guide plates and the surface of the shell, which can realize the flow of heat in two directions and make better use of the heat.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is 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 intended to limit the present invention.

[0029] It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be located directly or indirectly on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on this technical solution. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0030] Example 1

[0031] Please see the attached Figure 1 The present embodiment provides a combustion chamber, comprising a combustion chamber body 1, within which an inner hearth 11 is disposed. Preferably, the inner hearth 11 is an arc-shaped cavity. A connecting pipe 17 is disposed on the sidewall of the combustion chamber body 1, communicating with the inner hearth 11. The connecting pipe 17 is connected to a burner in a shallow ration heater to generate heat flow.

[0032] Specifically, the upper portion of the inner stove chamber 11 has a first outlet 18. Two parallel first guide plates 12 and a second guide plate 14 are disposed upward from the shell 16 of the combustion chamber body 1 along the first outlet 18. The ends of the two first guide plates 12 are respectively connected to one end of the second guide plate 14. A second outlet 13 is formed between the front ends of the two first guide plates 12 and the surface of the shell 16. It should be noted that the first outlet 18 is square and extends upward through the first and second guide plates 12, 14. It can be seen that the first and second outlets 18, 13, transfer the heat flow generated within the combustion chamber in two directions, allowing the heat to be more fully utilized.

[0033] In addition, flanges 15 are provided on all sides of the upper portion of the outer shell 16 of the combustion chamber body 1 to extend outward for installation of the entire combustion chamber.

[0034] Example 2

[0035] Please see the attached Figure 1-4 The purpose of this embodiment is to provide a heat flow channel using the combustion chamber as described above, including: an inner liner 2 and a fire isolation board 3.

[0036] The bottom wall of the inner liner 2 is provided with a connecting opening 23, and the side wall 21 of the inner liner 2 is provided with a heat outlet 24. The fire isolation board 3 is provided with multiple circular openings 31 arranged in a rectangular pattern. It should be noted that during installation, the first guide plate 12 and the second guide plate 14 are inserted into the connecting opening 23. The external shape and dimensions of the first and second guide plates 12 and 14 are the same as the internal shape and dimensions of the connecting opening 23, and the second outlet 13 faces away from the heat outlet 24. The lower surface of the flange 15 is in sealing contact with the upper surface of the bottom wall of the inner liner 2.

[0037] Furthermore, the fire isolation board 3 makes contact on three sides with the inner cavity 22 of the inner liner 2, sealingly covering the first guide plate 12 and the second guide plate 14. A gap is formed between the fire isolation board 3 and the bottom wall of the inner liner 2 to allow heat flow. The fire isolation board 3 is in sealing contact with the side wall 21 of the inner liner 2, where the heat flow outlet 24 is located. The length of the fire isolation board 3 is shorter than the length of the bottom wall of the inner liner 2, allowing heat flow to flow upward through the fire isolation board 3.

[0038] It can be seen from the above structural arrangement that the heat flow flows out of the combustion chamber, enters the channel between the bottom wall, side wall and lower surface of the fire partition board 3 of the inner tank 2 through the second outlet 13, and flows from left to right. Since the length of the fire partition board 3 is less than the length of the bottom wall of the inner tank 2, when the heat flow reaches the right side of the inner tank 2, it flows upward through the gap between the fire partition board 3 and the other side wall of the inner tank 2; at the same time, the heat flow can also flow upward through the first outlet 18 and the circular opening 31 on the fire partition board 3. When the upper part of the inner tank 2 is sealed and covered, the heat flow upward through the first outlet 18 and the heat flow circulated to the circular opening 31 through the second outlet 13 merge, realizing the heat flow circulation and full utilization of heat, supplementing heat for the heat flow circulated to the circular opening 31 through the second outlet 13 (the temperature of the heat flow circulated here has been reduced), and finally discharged through the hot flow outlet 24.

[0039] Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
