Description

Technical Field

[0001] This utility model relates to the field of cooking furnace technology, specifically to the heat insulation and anti-scalding structure of a fuel-fired cooking furnace body. Background Technology

[0002] Fuel-fired cookers are heating devices commonly used in home or commercial kitchens. They primarily use fuels (such as natural gas, alcohol, or solid fuels) to provide heat for heating, cooking, or steaming food. However, during operation, traditional fuel-fired cookers generate high temperatures from fuel combustion, causing the cooker surface to easily reach dangerous levels, posing a risk of burns. Furthermore, the internal heat utilization rate is low, with some heat lost through the outer shell, resulting in energy waste. Therefore, effectively insulating the cooker body while reducing the surface temperature to improve safety and energy efficiency has become a pressing issue.

[0003] Utility model patent CN211748834U discloses a multi-functional steaming oven. A heat insulation layer is fixedly installed on the inner wall of the outer shell, and a water tank is fixedly embedded in the inner wall of the heat insulation layer. The water tank is annularly arranged. An exhaust channel is provided between the inner wall of the water tank and the outer wall of the inner tub. Several exhaust holes are opened on the upper outer wall of the outer shell. A drain pipe is fixedly connected to the bottom of the inner tub. A water outlet pipe is fixedly installed at the bottom of the water tank. A water inlet pipe is fixedly installed on one side of the upper part of the water tank, and a safety exhaust pipe and a steam exhaust pipe are fixedly installed sequentially from top to bottom on the other side. The annular water tank between the outer shell and the inner tub allows the gas burner to heat the water inside the tank while simultaneously heating the bottom of the inner tub, improving the efficiency of heat energy utilization. Furthermore, the steam generated by the water tank can be reused, saving energy and reducing environmental pollution.

[0004] The existing technology described above achieves heat insulation of the furnace body by setting a heat insulation layer on the inner wall of the outer shell. However, the hot air generated during the cooking process will be discharged from the exhaust vents on the upper outer side of the outer shell, causing the outer shell temperature to gradually rise. Accidental contact with the outer shell of the cooking furnace may result in burns, posing a certain safety hazard, especially during prolonged operation or use under high-temperature conditions. Therefore, we propose a heat insulation and anti-scalding structure for the fuel-fired cooking furnace body. Through optimized design, this structure further improves safety and user experience while reducing heat loss and the risk of burns. Utility Model Content

[0005] The purpose of this invention is to provide a heat insulation and anti-scalding structure for the furnace body of a fuel cooking furnace, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The fuel-fired cooking furnace features a heat-insulating and anti-scalding structure, including a furnace body. The furnace body contains an inner tank for holding food or water to be heated, with its outer wall directly contacting the heating chamber for efficient heat transfer. An air inlet is located at the bottom of the furnace body to introduce external air to support fuel combustion. A partition is located near the bottom of the furnace body to separate the air chamber from the heating chamber and to provide a mounting base for the gas burner and refractory inner plate. A gas burner is located at the top of the partition and is connected to an external natural gas source via a gas pipe. Next, a refractory inner plate is provided at the top of the partition and near the outer edge. The top of the partition, the outer wall of the inner barrel, and the inner wall of the refractory inner plate form a heating chamber. The heating chamber serves as the core area for fuel combustion, and the inner barrel is efficiently heated by a gas burner. A heat insulation layer is provided between the outer wall of the refractory inner plate and the inner wall of the furnace body. The heat insulation layer is used to prevent heat from the heating chamber from being transferred to the outer wall of the furnace body, thereby reducing heat loss. An anti-scalding cover is provided on the outside of the furnace body. The anti-scalding cover uses a low thermal conductivity material to reduce the temperature of the outer shell and prevent burns when the user touches it.

[0008] Preferably, the bottom of the partition and the inner wall of the furnace body form an air cavity, and the bottom of the partition is provided with a plurality of air passage holes communicating with the heating cavity. The air passage holes are used to connect the air cavity and the heating cavity to assist air to flow upward.

[0009] Preferably, an exhaust vertical pipe is provided through the top of the furnace body, and the bottom end of the exhaust vertical pipe passes through the heat insulation layer and extends into the heating chamber. The exhaust vertical pipe is used to directionally discharge combustion exhaust gas to avoid the high-temperature airflow directly contacting the furnace body shell and causing temperature rise.

[0010] Preferably, the fire-resistant inner plate is made of austenitic stainless steel and has a thickness of 5-8 mm, providing high-temperature resistance.

[0011] Preferably, the heat insulation layer is made of ceramic fiber cotton material, which has high heat insulation performance, and the thickness of the heat insulation layer is 40-60mm.

[0012] Preferably, the heat-resistant cover is made of glass fiber reinforced polyetheretherketone material, and the thickness of the heat-resistant cover is 1-2mm, which takes into account both lightweight and low temperature conduction characteristics.

[0013] Preferably, the bottom edge of the furnace body is provided with two L-shaped lifting plates arranged symmetrically on the left and right. Each of the two L-shaped lifting plates has a handle on its opposite side and near the top. The L-shaped lifting plates and handles are used to provide a stable carrying fulcrum and keep the furnace away from the high temperature area to ensure operational safety.

[0014] Preferably, the bottom of the furnace body is provided with four legs arranged in a circular array. The legs are used to stably support the furnace body and maintain the distance between the bottom and the bearing surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The furnace body of this fuel cooking furnace has a heat insulation and anti-scalding structure. Through the double-layer heat insulation design of the heat insulation layer and the anti-scalding outer cover, the temperature of the furnace body shell is significantly reduced, preventing users from being scalded when they come into contact with it. At the same time, it reduces heat loss, improves the utilization rate of heat energy, and effectively solves the safety hazards of traditional cooking furnaces.

[0017] 2. The fuel cooking furnace body has a heat insulation and anti-scalding structure. It adopts an exhaust vertical pipe to directionally discharge combustion exhaust gas, avoiding direct contact between high-temperature airflow and the furnace shell, thus enhancing equipment safety. The symmetrical design of the L-shaped lifting plate and handle enables easy transport away from high-temperature areas. Attached Figure Description

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] The fuel-fired cooking furnace has a heat insulation and anti-scalding structure, including a furnace body 100. An inner tank 200 is located inside the furnace body 100, used to hold food or water to be heated. Its outer wall directly contacts the heating chamber 130 for efficient heat transfer. An air inlet 101 is located at the bottom of the furnace body 100 to introduce external air to support fuel combustion. A partition 110, made of heat-insulating material, is located inside the furnace body 100 near the bottom to reduce heat transfer. The partition 110 separates the air chamber 120 from the heating chamber 130 and provides a mounting base for the gas burner 400 and the refractory inner plate 300. The gas burner 400 is located at the top of the partition 110. The gas burner 400 is connected to a guide tube... The gas pipe is connected to an external natural gas source. A refractory inner plate 300 is provided on the top of the partition 110 and near the outer edge. The top of the partition 110, the outer wall of the inner barrel 200, and the inner wall of the refractory inner plate 300 form a heating chamber 130. The heating chamber 130 serves as the core area for fuel combustion. The inner barrel 200 is efficiently heated by the gas burner 400. A heat insulation layer 500 is provided between the outer wall of the refractory inner plate 300 and the inner wall of the furnace body 100. The heat insulation layer 500 is used to block the heat from the heating chamber 130 from being transferred to the outer wall of the furnace body 100, thereby reducing heat loss. An anti-scalding cover 600 is provided on the outside of the furnace body 100. The anti-scalding cover 600 uses a low thermal conductivity material to reduce the temperature of the outer shell and prevent burns when the user touches it.

[0027] In this embodiment, the bottom of the partition 110 and the inner wall of the furnace body 100 form an air cavity 120. The bottom of the partition 110 is provided with a plurality of air passage holes 111 that communicate with the heating cavity 130. The air passage holes 111 are used to connect the air cavity 120 and the heating cavity 130 to assist air to flow upward.

[0028] Specifically, an exhaust vertical pipe 700 is provided through the top of the furnace body 100. The bottom end of the exhaust vertical pipe 700 passes through the heat insulation layer 500 and extends into the heating chamber 130. The exhaust vertical pipe 700 is used to directionally discharge combustion exhaust gas to avoid the high-temperature airflow directly contacting the outer shell of the furnace body 100 and causing temperature rise.

[0029] Furthermore, the fire-resistant inner plate 300 is made of austenitic stainless steel and has a thickness of 5-8mm, providing high-temperature resistance.

[0030] Furthermore, the thermal insulation layer 500 is made of ceramic fiber cotton material, which has high thermal insulation performance, and the thickness of the thermal insulation layer 500 is 40-60mm.

[0031] Furthermore, the heat-resistant cover 600 is made of glass fiber reinforced polyetheretherketone material, and the thickness of the heat-resistant cover 600 is 1-2mm, taking into account both lightweight and low-temperature conduction characteristics.

[0032] Furthermore, the bottom edge of the furnace body 100 is provided with two L-shaped lifting plates 800 arranged symmetrically on the left and right. The opposite sides of the two L-shaped lifting plates 800 and the handles 810 are provided near the top. The L-shaped lifting plates 800 and the handles 810 are used to provide a stable carrying fulcrum, away from the high temperature area to ensure operational safety.

[0033] Furthermore, the bottom of the furnace body 100 is provided with four support legs 900 arranged in a circular array. The support legs 900 are used to stably support the furnace body 100 and maintain the distance between the bottom and the bearing surface.

[0034] In this embodiment, the heat insulation and anti-scalding structure of the fuel-fired cooking furnace body is used as follows: First, the food or water to be heated is placed into the inner tank 200. Then, the gas burner 400 is ignited. The flame generated by the fuel combustion heats the bottom of the inner tank 200 in the heating chamber 130. At the same time, external air enters the air chamber 120 through the air inlet 101 at the bottom of the furnace body 100 and flows upward to the heating chamber 130 through the air passage 111 at the bottom of the partition 110. During the combustion process, the heat insulation layer 500 prevents the heat from the heating chamber 130 from being transferred to the outer wall of the furnace body 100, and the anti-scalding cover 600 further reduces the surface temperature of the outer shell. The combustion exhaust gas is discharged directionally through the exhaust vertical pipe 700 that runs through the top of the furnace body 100 to prevent the high-temperature airflow from contacting the outer shell. When transporting, the symmetrically arranged L-shaped lifting plates 800 and handles 810 are used to operate away from the high-temperature area to ensure safety.
