Technical Field
[0001] This utility model relates to the field of food cooking equipment technology, and in particular to a gas-fired open-top fryer. Background Technology
[0002] In the food cooking industry, gas-fired open-top fryers are widely used for frying fried foods such as French fries and chicken nuggets due to their advantages, such as easy cleaning of the oil cylinder. However, existing gas-fired open-top fryers on the market generally suffer from unreasonable structural design problems:
[0003] On the one hand, the furnace body lacks effective heat insulation and heat shielding structure. The high temperature generated during the heating process can easily be conducted outward through the side wall and bottom of the furnace body, causing the wall near the furnace body to be baked (i.e., wall burning) and the ground below the furnace body to be scorched by high temperature (i.e. floor burning). This not only poses a safety hazard, but may also damage the interior decoration and floor materials.
[0004] On the other hand, some fryers have poor insulation in their oil cylinders, resulting in significant heat loss, which reduces heating efficiency and increases gas consumption. At the same time, the fryer body is difficult to clean, making it difficult to meet the hygiene requirements of food processing.
[0005] To address the aforementioned problems, this utility model provides a gas-fired open-face fryer. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a gas-fired open-face fryer, which solves the problems mentioned in the background section.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas-fired open-face fryer, including a furnace body, an oil cylinder is embedded in the top of the furnace body, and a combustion chamber is provided inside the furnace body below the oil cylinder. A flue is provided on the rear side of the interior of the furnace body, the flue is connected to the combustion chamber, and a smoke exhaust port is provided at the top of the flue on the rear side of the upper end of the furnace body.
[0008] A front heat baffle is provided on the front side of the furnace body, and a control door is hinged to the front side of the furnace body. A control compartment is formed between the front heat baffle and the control door, and a temperature limiter, a temperature controller and a control knob are installed in the control compartment.
[0009] The cylinder is equipped with a flattening net inside, and a thermocouple is installed at the bottom of the cylinder. Two hollowed-out frying baskets are placed on the flattening net.
[0010] The furnace body is symmetrically provided with a left heat baffle plate and a right heat baffle plate on both sides, and a rear sealing plate is installed on the rear side of the furnace body by bolts. A bottom heat baffle plate is provided at the inner bottom of the furnace body, and heat insulation cotton plates are provided on the outer sides of the oil cylinder.
[0011] As a further technical solution of this utility model, a U-shaped gas pipe is installed inside the combustion chamber, and gas nozzles are evenly distributed on the U-shaped gas pipe. A ignition bracket is installed inside the furnace body near the U-shaped gas pipe, and a ignition source is fixed on the ignition bracket.
[0012] As a further technical solution of this utility model, one end of the U-shaped gas pipe is connected to a gas supply pipe, and the U-shaped gas pipe is connected to an inlet pipe extending out of the bottom of the furnace body through the gas supply pipe. A gas valve is installed on the inlet pipe, and the inlet pipe and the gas valve are installed on the bottom heat baffle plate.
[0013] As a further technical solution of this utility model, the inner bottom of the oil cylinder is connected to an oil drain pipe extending to the control chamber, and a valve is provided on the oil drain pipe.
[0014] As a further technical solution of this utility model, the left heat shield, right heat shield, bottom heat shield, rear sealing plate and front heat shield are all made of aluminum plate, and the heat insulation cotton board is made of aluminum silicate material.

[0017] This utility model provides a gas-fired open-face fryer, which has the following advantages compared with the prior art:
[0018] 1. This invention relates to a gas-fired open-face fryer. By installing aluminized heat baffles on both sides, bottom, rear, and front of the furnace body, and aluminum silicate insulation cotton board on the outside of the oil cylinder, a double heat insulation protection is formed, which effectively blocks the conduction of heat to the outside of the furnace body. This completely solves the problem of burning the walls and floors of existing products, improves the safety of equipment use, and the combination of aluminized heat baffles and aluminum silicate insulation cotton board not only reduces heat loss, but also improves the heating efficiency of the oil cylinder and reduces gas consumption.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-3 This utility model provides a technical solution for a gas-fired open-face fryer: a gas-fired open-face fryer includes a furnace body 1, with support legs at the four corners of the bottom of the furnace body 1, and the furnace body 1 is also connected to an external power source via cables. A left heat shield 101 and a right heat shield 102 are symmetrically arranged on both sides of the furnace body 1, and a rear sealing plate 4 is bolted to the rear side of the furnace body 1. A bottom heat shield 103 is provided at the inner bottom of the furnace body 1. The left heat shield 101, right heat shield 102, bottom heat shield 103, rear sealing plate 4, and front heat shield are all made of aluminized plate. The left heat shield 101 and right heat shield 102 are fixed to both sides of the furnace body 1 with high-temperature resistant bolts. The bottom heat shield 103 is also fixed to the inner bottom of the furnace body 1 with bolts. The rear sealing plate 4 is bolted to the rear side of the furnace body 1, and the front heat shield is bolted to the inner front side of the furnace body. Thus, the main frame of the furnace body 1 can be assembled in a modular manner.
[0029] like Figure 1-4As described above, an installation hole matching the oil cylinder is opened on the top of the furnace body, and the oil cylinder is embedded in the installation hole. A flattening net 22 is set inside the oil cylinder 2, and a thermocouple 16 is installed at the bottom of the oil cylinder 2. Two hollow frying baskets 21 are placed on the flattening net 22, and heat-insulating handles are installed on the frying baskets 21. Heat-insulating cotton boards are set on the outer side of the oil cylinder 2. The heat-insulating cotton boards are made of aluminum silicate. The bottom of the inner part of the oil cylinder 2 is connected to an oil drain pipe 23 that extends to the control compartment. A valve is set on the oil drain pipe 23, which is convenient to open the control door 5 when the use is over or when the oil is changed, connect the oil pipe to the oil drain pipe 23, open the valve, and the oil in the oil cylinder 2 can be drained.
[0030] like Figure 5 and 6 As shown, the interior of the furnace body 1 is provided with a combustion chamber located below the oil cylinder 2. The interior rear side of the furnace body 1 is provided with a flue 31, which is connected to the combustion chamber. The top of the flue 31 is provided with a smoke exhaust port 3 located at the upper rear side of the furnace body 1. The flue 31 and the smoke exhaust port 3 are both made of aluminum-plated plate to improve their heat insulation effect.
[0031] A front heat baffle is provided on the front side of the furnace body 1, and a control door 5 is hinged to the front side of the furnace body 1. A control compartment is formed between the front heat baffle and the control door 5, and a temperature limiter 51, a temperature controller 52 and a control knob 53 are installed in the control compartment.
[0032] A U-shaped gas pipe 13 is installed inside the combustion chamber. The bottom of the furnace body 1 is separated from the combustion chamber by a metal partition. The U-shaped gas pipe 13 is mounted on the metal partition by a bracket. Gas nozzles 14 are evenly distributed on the U-shaped gas pipe 13. A ignition bracket 15 is installed inside the furnace body 1 near the U-shaped gas pipe 13. A ignition source is fixed on the ignition bracket 15. One end of the U-shaped gas pipe 13 is connected to a gas supply pipe 17. The U-shaped gas pipe 13 is connected to an air inlet pipe 11 extending out of the bottom of the furnace body 1 through the gas supply pipe 17. A gas valve 12 is installed on the air inlet pipe 11. The air inlet pipe 11 and the gas valve 12 are mounted on the bottom heat baffle plate 103.
[0033] The working principle of this utility model is as follows: When in use, the operator sets the target oil temperature by controlling the knob 53, inserts the ignition gun into the furnace body 1, and manually ignites the flame on the flame holder 15. The flame generated by the burning flame heats the thermocouple 16. The thermocouple 16 generates an electric potential after being heated, which triggers the temperature controller 52 to start working.
[0034] When the thermostat 52 detects that the oil temperature in the oil cylinder 2 is lower than the set temperature, it sends a signal to the gas valve 12 to control the gas valve 12 to open. Gas (natural gas or liquefied gas) enters through the inlet pipe 11, and flows into the U-shaped gas pipe 13 through the gas valve 12 and the gas supply pipe 17 in sequence. Finally, it is ejected at high speed from the gas nozzle 14 on the U-shaped gas pipe 13. The ejected gas is ignited by a nearby flame and forms a flame in the combustion chamber. The heat generated by the flame is conducted upward to the oil cylinder 2 to heat the grease in the oil cylinder 2.
[0035] When thermocouple 16 does not detect a flame, it sends a signal to gas valve 12 to control gas valve 12 to close, stop gas supply, and ensure equipment safety.
[0036] In addition, the operator holds the heat-insulating handle of the frying basket 21, puts the food to be fried (such as French fries and chicken nuggets) into the hollow frying basket 21, and then places the frying basket 21 on the flat net 22 of the oil cylinder 2 to fry the food. After frying, the frying basket 21 can be taken out. When it is necessary to clean the oil cylinder 2, the valve on the drain pipe 23 is opened to discharge the waste oil in the oil cylinder 2 through the drain pipe 23 to complete the cleaning.
[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
