[0002] With the development of technology, various cooking equipment has emerged on the market to meet different cooking needs. For some commercial equipment, such as catering establishments or canteens that need to cook ingredients quickly or in large quantities, large woks can provide powerful assistance.

[0003] Existing large wok ovens suffer from numerous technical defects. On one hand, the ovens require prolonged high-temperature combustion during operation, resulting in excessively high surface temperatures. This not only increases the risk of burns to operators but also raises the ambient temperature, negatively impacting the kitchen work environment. On the other hand, their internal insulation is poor, leading to low thermal efficiency and high energy consumption, resulting in poor energy conservation. For example, in some traditional large wok ovens, a significant amount of heat is lost through the oven body during cooking, failing to effectively heat the food and causing substantial energy waste. Furthermore, some ovens use only bricks for insulation, resulting in poor insulation and a heavy oven body, hindering installation, relocation, and maintenance. For instance, some large wok ovens using brick insulation are quite heavy, making them extremely inconvenient to move when rearranging kitchen layouts. Therefore, this invention proposes an energy-saving large wok oven to at least partially address these user pain points in existing operating environments. Utility Model Content

[0004] In view of the above problems, this utility model proposes an energy-saving large wok stove that overcomes or at least partially solves the above problems.

[0020] By incorporating a conical reflector 103 at the bottom of the inner liner 102, heat generated by the burner head 108 can be reflected back into the inner liner 102, reducing heat loss and improving thermal efficiency. For example, in actual cooking, compared to a wok without a reflector, thermal efficiency can be increased by approximately 20%. Simultaneously, insulation cotton is filled between the reflector and the inner liner, and heat insulation cotton is filled between the inner and outer liners, effectively reducing the surface temperature of the oven and decreasing energy consumption. For example, the surface temperature of the oven can be reduced to below 50°C, resulting in a reduction of energy consumption of approximately 15%.

[0021] The inner liner 102 is provided with a smoke outlet 122 located above the reflector 103; the smoke outlet 122 is connected to the chimney 303 through the lower port 202 of the chimney; the chimney 303 extends out of the furnace body 101. The smoke outlet 122, connected to the chimney 303 through the lower port 202, allows the exhaust gas generated during combustion to be smoothly discharged, ensuring complete combustion within the furnace and further improving thermal efficiency. For example, it can increase combustion efficiency by approximately 10%. Furthermore, a back plate 106 is provided at the upper end of one side of the furnace body 101; the chimney 303 is located inside the back plate 106 and extends beyond the upper end of the back plate 106.

[0024] Furthermore, the outer liner 301 is provided with baffles 302 at the front and sides; the upper end of the outer liner 301 is provided with an upper cover plate 305; the upper end of the upper cover plate 305 is covered with a furnace surface 105; the upper end of the inner liner 102 extends from the upper cover plate 305 and the furnace surface 105 in sequence. The baffles 302 and the upper cover plate 305 on the outer liner 301, along with the furnace surface, make the furnace structure more compact and easier to clean and maintain. For example, during routine cleaning, the cover plate can be easily removed for washing. The baffles 302 are connected to the side wall of the outer liner 301 via a snap-fit ​​structure, and fire-resistant silicone strips are added to the joints.

[0025] The back panel 106 is also equipped with a rotatable and adjustable faucet 104, and the rotation trajectory of the faucet 104 passes above the inner pot 102. The rotatable and adjustable faucet 104 facilitates adding water during cooking, improving operational convenience. For example, during cooking, the chef can easily rotate the faucet to add water to the wok placed in the inner pot 102. In addition, water can also be drained from the cooktop 105 to cool it down.

[0026] Furthermore, the air-pump linkage device 304 is also equipped with a regulating valve 201, the regulating handle of which extends out of the baffle 302. This extension of the regulating valve 201 out of the baffle 302 facilitates the operator's adjustment of the air-pump linkage device, controlling the heat output and improving cooking flexibility. For example, the chef can conveniently adjust the heat output from outside the oven to meet the cooking needs of different dishes.

[0027] The bottom of the outer liner 301 is equipped with adjustable support feet 107. The adjustable support feet 107 can adapt to different installation environments and ensure that the stove body is placed stably. For example, in the case of uneven kitchen floors, the stove body can be kept level by adjusting the support feet. The outer liner 301 is made of galvanized steel sheet. It has good corrosion resistance, extending the service life of the furnace body. For example, compared with ordinary steel sheet, the service life of the outer liner 301 made of galvanized steel sheet can be extended by about 3 to 5 years under the same operating environment.

[0028] like Figure 1-2 As shown, this energy-saving wok stove includes a stove body 101, whose outer liner 301 is made of galvanized sheet, with a cylindrical inner liner 102 nested in the center. A burner head 108 is installed at the bottom of the outer liner 301, and the burner head 108 is connected to a gas-air linkage device 304 via a gas pipeline, extending upwards into the inner liner 102. A stainless steel conical reflector 103 is installed around the burner head 108 at the bottom of the inner liner 102, with a reflective surface tilt angle of 45°, for reflecting flame heat towards the bottom of the wok.

[0029] The core thermal insulation structure includes: between the reflector 103 and the inner liner 102, high-temperature resistant ceramic fiber insulation cotton (density ≥128kg / m³) is filled. 3 The inner liner 102 and the outer liner 301 are filled with double-layer aluminum silicate insulation cotton (50mm thick) to prevent heat from escaping.

[0030] The chimney system includes a flue outlet 122 on the side wall of the inner liner 102, which can be connected to the lower port 202 of the chimney via a flange. The chimney 303 extends to the top of the furnace body along the built-in channel of the back plate 106. The grid blades 231 of the chimney cap 203 are arranged radially to prevent backdraft.

[0031] The observation hole 121 is located on the side of the inner tank 102 and is connected to the front baffle 302 of the furnace body through the quartz glass observation tube 204. The back plate 106 is equipped with a 180° rotating faucet 104, whose water discharge trajectory covers the top of the inner tank 102.

[0037] A conical reflector 103 is installed around the burner head 108 at the bottom of the inner liner 102. The reflector is made of a high-temperature resistant material with good reflective properties, such as ceramic reflective material. During installation, ensure that the gap between the reflector and the inner liner is uniform to allow for the filling of insulation cotton. Insulation cotton is then filled tightly into the gap between the reflector 103 and the inner liner 102 to ensure effective insulation. Similarly, heat insulation cotton is filled tightly into the gap between the inner liner 102 and the outer liner 301 to reduce heat transfer.

[0038] A smoke outlet 122 is provided on the inner liner 102 at the upper end of the reflector 103. The size of the smoke outlet should be reasonably designed according to the combustion power and exhaust requirements of the furnace head. The smoke outlet is connected to the chimney 303 through the lower port 202 of the chimney, ensuring a firm connection and good sealing. The chimney 303 should extend beyond the furnace body 101, and its verticality must be ensured during installation.

[0039] A back plate 106 is installed on the upper part of one side of the furnace body 101, and the chimney 303 is placed inside the back plate 106, ensuring that the chimney extends beyond the upper end of the back plate 106. The back plate must be securely installed to protect the chimney and enhance its appearance. A chimney cap 203 is installed at the upper end of the chimney 303. The chimney cap's grating blades 231 should be installed flexibly, allowing for easy angle adjustment to control the amount of smoke emitted. A viewing hole 121 is opened in the inner liner 102 above the burner head 108. The viewing hole is connected to the viewing port on the furnace body 101 via a viewing tube 204 to ensure a clear view. Baffles 302 are installed in front of and on both sides of the outer liner 301. An upper cover plate 305 is installed on the upper end of the outer liner 301, covering the furnace surface 105. During installation, ensure that the connections between the covers are tight, facilitating disassembly and installation, and making cleaning and maintenance convenient. An upper cover plate 305 and a cooktop 105 extend sequentially from the upper port of the inner tank 102. A rotatable and adjustable faucet 104 is installed on the back plate 106, ensuring that the faucet's rotation path passes over the inner tank 102 for easy water filling. After installation, the faucet's rotational flexibility should be tested.

[0040] Install a regulating valve 201 on the air-pump linkage device 304, extending the regulating handle of the valve out of the baffle 302 for easy adjustment by the operator. After installation, test the regulating valve's function to ensure it is working properly. Install adjustable support feet 107 at the bottom of the outer liner 301. During installation, ensure the support feet are adjustable to maintain stability of the furnace body under different ground conditions.
