Description

Technical Field

[0001] This utility model relates to the field of gas equipment, specifically to a wok stove that facilitates drainage. Background Technology

[0002] Commercial kitchen woks (such as Chinese gas woks) often generate large amounts of oil, food residue, and cleaning wastewater during cooking. Existing woks typically have drains on the work surface to remove water, but there's usually no active drainage for water accumulating inside the burner during cleaning or spillage. The burner relies primarily on the high temperature of combustion to evaporate and bake away moisture; however, if water remains inside the burner after use and shutdown, it can easily lead to ignition failure, flame sensor malfunction in the flameout protection device, and internal corrosion, shortening the burner's lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a wok stove that allows for convenient and active drainage of water accumulated inside the burner head.

[0004] To achieve the above objectives, this utility model provides a convenient drainage wok, comprising a wok basin, a burner, a flue pipe, and a drain pipe. The wok basin has a chamber, and the burner is located within the chamber. From the inside out, the burner has a combustion chamber, a premixed gas chamber, and an air-cooled chamber arranged sequentially. The combustion chamber and the premixed gas chamber are connected. The flue pipe is located at the bottom of the wok basin and is connected to the chamber. The first end of the drain pipe passes through the air-cooled chamber and the premixed gas chamber and is connected to the combustion chamber. The first end of the drain pipe is located on the bottom wall of the combustion chamber, and the end face of the first end of the drain pipe is not higher than the bottom wall of the combustion chamber. The second end of the drain pipe is connected to the flue pipe.

[0005] As can be seen from the above solution, the drain pipe can actively discharge the water accumulated in the burner head through the flue pipe, effectively avoiding ignition failure caused by water accumulation and flame sensor malfunction in the flameout protection device. This helps reduce equipment failure rate, extend the service life of the burner head, and prevent internal corrosion. By connecting the drain pipe and the flue pipe, this utility model achieves integrated functions of flue gas exhaust and drainage, which helps simplify the overall structure and save piping space.

[0006] A further design is that the exhaust pipe includes a horizontal pipe and two vertical pipes. The first end of each of the two vertical pipes is connected to both sides of the chamber, and the second end of each of the two vertical pipes is connected to the horizontal pipe. The drain pipe is located between the two vertical pipes.

[0007] As can be seen from the above scheme, setting up a flue pipe helps to reduce the resistance of flue gas and increases the disturbance of flue gas, thereby eliminating the howling noise caused by resonance that often occurs in the frying oven.

[0008] A further option is to also provide a platform section for the exhaust pipe, which is located between two longitudinal pipes. The platform section has an installation hole that communicates with the interior of the transverse pipe, and the second end of the drain pipe is located in the installation hole.

[0009] As can be seen from the above scheme, by setting up a platform, drilling operations can be facilitated.

[0010] A further solution is to use high-temperature resistant materials for the drainage pipes.

[0011] A further embodiment is that the burner includes a main gas pipe, a pilot flame device, and a nozzle. The pilot flame device is located inside the combustion chamber. One end of the main gas pipe passes through the air-cooled chamber and is connected to the premixed gas chamber. A pilot flame connecting pipe is connected to the main gas pipe. The pilot flame connecting pipe has a free end, and the nozzle is detachably connected to the free end of the pilot flame connecting pipe.

[0012] A further option is to include nozzles for both liquefied petroleum gas (LPG) and natural gas.

[0013] As can be seen from the above scheme, the above settings make it convenient to select the appropriate nozzle according to the type of gas.

[0014] A further embodiment includes a control component for the wok, comprising a controller, a main gas supply pipe, a pilot flame gas supply pipe, a main fire gas supply pipe, a first proportional solenoid valve, a second proportional solenoid valve, a third proportional solenoid valve, and a blower. The main gas supply pipe is connected to both the pilot flame gas supply pipe and the main fire gas supply pipe. The pilot flame gas supply pipe is connected to the pilot flame connecting pipe via a nozzle. The main fire gas supply pipe is connected to the main gas pipe. The first proportional solenoid valve is connected to the main gas supply pipe, the second proportional solenoid valve is connected to the pilot flame gas supply pipe, and the third proportional solenoid valve and the blower are both connected to the main fire gas supply pipe. The controller is electrically connected to the first proportional solenoid valve, the second proportional solenoid valve, the third proportional solenoid valve, and the blower.

[0015] As can be seen from the above scheme, the main gas supply pipe, the pilot flame gas supply pipe and the main fire gas supply pipe are independent of each other and are controlled by their respective proportional valves. They can be controlled as a whole or individually, which facilitates the control of burner ignition and the adjustment of firepower after ignition.

[0016] A further proposed solution is to install a premixer at the air inlet of the blower, and connect the main fire gas supply pipe to the blower through the premixer.

[0017] As can be seen from the above scheme, by setting a premixer, the concentration of the gas introduced into the fan can be kept at a preset value, thereby ensuring complete combustion and preventing the generation of excessive harmful gases that could endanger the environment.

[0018] A further embodiment is that the furnace basin includes a basin body, a bracket, and an energy-concentrating reflector. The chamber is located inside the basin body, and both the bracket and the energy-concentrating reflector are located inside the chamber. The energy-concentrating reflector has multiple first exhaust holes, the bracket has multiple second exhaust holes, and the bottom wall of the basin body has a third exhaust hole. The first, second, and third exhaust holes are all connected to the chamber, and the exhaust pipe is connected to the third exhaust hole.

[0019] A further option is to install the burner on the bottom wall of the basin, with multiple mounting seats on the bottom wall of the basin, and multiple ears on the burner, which are mounted on the mounting seats. Attached Figure Description

[0030] See Figures 1 to 2 The frying pan provided in this embodiment for convenient drainage includes a pan 1, a burner 2, a flue pipe 3, a drain pipe 4, and a control assembly 5. The flue pipe 3 is located at the bottom of the pan 1, and the two ends of the drain pipe 4 are connected to the pan 1 and the flue pipe 3, respectively. The burner 2 is equipped with an ignition device and a flameout protection device.

[0031] The control component 5 includes a controller 51, a main gas supply pipe 59, a pilot flame gas supply pipe 52, a main flame gas supply pipe 53, a first proportional solenoid valve 54, a second proportional solenoid valve 55, a third proportional solenoid valve 56, and a fan 57.

[0032] The main gas supply pipe 59 is connected to both the pilot flame gas supply pipe 52 and the main flame gas supply pipe 53. A first proportional solenoid valve 54 is connected to the main gas supply pipe 59, a second proportional solenoid valve 55 is connected to the pilot flame gas supply pipe 52, and a third proportional solenoid valve 56 and a blower 57 are both connected to the main flame gas supply pipe 53. A proportional solenoid valve is a valve capable of continuously or proportionally controlling the flow rate of fluids (liquids, gases, and oils, etc.) according to an input signal. The first proportional solenoid valve 54, the second proportional solenoid valve 55, and the third proportional solenoid valve 56 can be integrated into a single valve or can be independent valves; this embodiment does not impose any limitations.

[0033] The controller 51 is electrically connected to the first proportional solenoid valve 54, the second proportional solenoid valve 55, the third proportional solenoid valve 56, the fan 57, the ignition device, and the flameout protection device. The controller 51 can control the opening and closing status of each proportional solenoid valve, and can also control the airflow of the fan 57 to achieve multiple levels of firepower adjustment. In this embodiment, the firepower setting of the wok is P0, P1 to P5, with the firepower gradually increasing from P0 to P5.

[0034] A premixer 58 is provided at the air inlet of the blower 57, and the main fire gas supply pipe 53 is connected to the blower 57 through the premixer 58. The premixer 58 in this embodiment is the premixer 58 of the applicant's earlier application with publication number CN222811756U, and will not be described in detail here.

[0035] See Figures 3 to 9 The furnace basin 1 includes a basin body 11, an energy-concentrating reflector 12, and a bracket 13. A chamber 111 is provided within the basin body 11. Both the energy-concentrating reflector 12 and the bracket 13 are located within the chamber 111, with the energy-concentrating reflector 12 positioned above the bracket 13. Multiple first exhaust holes 121 are evenly spaced along the circumference of the energy-concentrating reflector 12. Multiple second exhaust holes 131 are provided along the circumference of the bracket 13. Both the first exhaust holes 121 and the second exhaust holes 131 communicate with the chamber 111. The bottom wall of the basin body 11 has a central hole 112, two third exhaust holes 113, and multiple mounting seats 114. The mounting seats 114 are distributed around the circumference of the central hole 112, and the two third exhaust holes 113 are located on either side of the central hole 112.

[0036] The burner 2 is housed within chamber 111, specifically within the central hole 112. Multiple lugs 21 are provided on the outer peripheral wall of the burner 2, and these lugs 21 are fixed to the mounting base 114 by screws. From the inside out, the burner 2 comprises a combustion chamber 22, a premixed gas chamber 23, and an air-cooled chamber 24. Multiple connecting grooves 221 are formed on the upper wall of the combustion chamber 22, evenly spaced along the circumference of the combustion chamber 22. These grooves connect to both the combustion chamber 22 and the premixed gas chamber 23, facilitating the entry of premixed gas into the combustion chamber 22. The air-cooled chamber 24 is located on the outer periphery of the premixed gas chamber 23. It protects the burner 2 from damage caused by the high-temperature flue gas within the basin 11 and prevents the high-temperature flue gas from igniting the combustible gas in the burner 2, thus avoiding a combustion explosion. Both sides of the air-cooled cavity 24 are equipped with an air inlet pipe and an air outlet pipe. The air inlet pipe is connected to the outside, and the air outlet pipe can be connected to the main air pipe 25.

[0037] The flue pipe 3 is located at the bottom of the furnace basin 1. The flue pipe 3 includes a horizontal pipe 31 and two vertical pipes 32. The first end of each of the two vertical pipes 32 is connected to two third air extraction holes 113, and then connected to the chamber 111. The second end of each of the two vertical pipes 32 is connected to the horizontal pipe 31.

[0038] The first end of the drain pipe 4 passes through the air-cooled chamber 24, the premixed gas chamber 23, and connects to the combustion chamber 22. Specifically, the first end of the drain pipe 4 is located on the bottom wall of the combustion chamber 22, and the end face of the first end of the drain pipe 4 is not higher than the bottom wall of the combustion chamber 22, so as to facilitate the drainage of all accumulated water in the combustion chamber 22. The second end of the drain pipe 4 connects to the exhaust pipe 3, and the drain pipe 4 is located between the two longitudinal pipes 32.

[0039] The exhaust pipe 3 is also provided with a platform section 33, which is located between two longitudinal pipes 32. The platform section 33 has an installation hole 331 that communicates with the interior of the transverse pipe 31. The second end of the drain pipe 4 is located in the installation hole 331.

[0040] The drain pipe 4 is made of high-temperature resistant material. Specifically, the drain pipe 4 can be made of stainless steel, iron or other metal materials.

[0041] The burner 2 also includes a main gas pipe 25, a pilot flame device 27, and a nozzle 28. The pilot flame device 27 is located inside the combustion chamber 22 and communicates with the premixed combustion chamber 23. The pilot flame device 27 is close to the ignition device and is used for ignition. One end of the main gas pipe 25 is connected to the premixed gas chamber 23, and the other end of the main gas pipe 25 is connected to the air outlet of the blower 57 or the main combustion gas supply pipe 53 to supply main combustion gas. A pilot flame connecting pipe 26 is connected to the main gas pipe 25. The end of the pilot flame connecting pipe 26 away from the main gas pipe 25 is a free end, and the nozzle 28 is detachably connected to the free end. The pilot flame supply pipe 52 is connected to the pilot flame connecting pipe 26 through the nozzle 28. There is a preset distance between the connection port of the pilot flame connection pipe 26 and the main gas pipe 25 and the premixed gas chamber 23, so that the gas in the pilot flame connection pipe 26 first enters the main gas pipe 25 and premixes with the air, which facilitates uniform mixing of gas and air and ensures that the gas can be fully burned in the future.

[0042] Nozzle 28 is detachably connected to both the pilot flame connection pipe 26 and the pilot flame gas supply pipe 52. In this embodiment, nozzle 28 includes a liquefied petroleum gas (LPG) nozzle and a natural gas nozzle. The inner diameter of the natural gas nozzle is slightly larger than that of the LPG nozzle, facilitating the selection of a suitable nozzle based on the type of gas. That is, when the gas is LPG, the LPG nozzle is selected; when the gas is natural gas, the natural gas nozzle is selected.

[0043] In summary, the drain pipe 4 of this invention can actively drain the water accumulated in the burner head through the exhaust pipe 3, effectively avoiding ignition failure caused by water accumulation and flame sensor malfunction in the flameout protection device. It also reduces equipment failure rate, extends the burner head's service life, and prevents internal corrosion. By connecting the drain pipe 4 to the exhaust pipe 3, this invention achieves integrated exhaust and drainage functions, simplifying the overall structure and saving piping space.

[0044] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
