Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a smoke exhaust structure for a gas stove. Background Technology

[0002] A gas stove is a kitchen appliance that uses liquefied petroleum gas (LPG), manufactured gas, natural gas, or other gaseous fuels for direct-fire heating; its widespread use is well-known. In terms of gas source, gas stoves are mainly divided into LPG stoves, manufactured gas stoves, and natural gas stoves. In terms of burner size, they are divided into single-burner, double-burner, and multi-burner stoves. During cooking, the gas stove supplies heat to the bottom of the appliance, and the grease from the food inside produces fumes due to the high temperature, which can affect the respiratory health of the person cooking. Therefore, a fume extraction system is needed to remove these fumes.

[0003] In existing gas stove exhaust structures, after absorbing cooking fumes, the fumes come into direct contact with the blades of the exhaust fan. This causes the cooled fumes to liquefy and accumulate as grease on the fan blades, increasing their weight and reducing their rotational speed. This negatively impacts the exhaust efficiency, leading to a higher power requirement. To address this technical problem, this application proposes a new exhaust structure for gas stoves. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gas stove exhaust structure. This structure aims to improve the problem in existing technologies where grease accumulates on the fan blades after the fan comes into contact with fumes, increasing the weight of the blades, reducing their rotational speed, and thus affecting the fume extraction efficiency of the exhaust structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A gas stove exhaust structure includes:

[0007] The chassis is divided into a disinfection chamber and an equipment chamber by a partition. The disinfection chamber is located in front of the equipment chamber. A gas stove for cooking is installed on the top side of the chassis. The disinfection chamber is equipped with multiple dish cabinets for storing washed dishes.

[0008] A smoke baffle frame is used to reduce the spread of cooking fumes. The smoke baffle frame is fixedly connected to the top rear end of the gas stove. The smoke baffle frame has an internal cavity. A mesh plate is fixedly connected to the front of the cavity to prevent foreign objects from entering. A volute is fixedly connected to the inside of the equipment cavity. The cavity and the equipment cavity are connected by a fume duct and to the volute. The volute is equipped with a fan blade assembly driven by a drive source to simultaneously and quickly drain and exhaust the dishes inside the dish cabinet.

[0009] Furthermore, the fume duct includes a filter chamber located at the bottom of the volute. The input end of the filter chamber is fixedly connected to a kitchen appliance smoke inlet pipe. The top end of the smoke inlet pipe passes through the casing and the gas stove in sequence and is located inside the cavity. The filter chamber is filled with porous activated carbon. An oil drain pipe is fixedly connected to the output end of the bottom side of the filter chamber.

[0010] Furthermore, the input end of the volute is fixedly connected to the top output end of the filter chamber, and the output end of the volute penetrates through the right side of the outer wall of the chassis.

[0011] Furthermore, the fan blade assembly includes a rotating shaft rotatably connected to the middle of the volute. The front end of the rotating shaft passes through the front side of the outer wall of the volute and the rear side of the inner wall of the disinfection chamber in sequence. A first fan blade is fixedly connected to the rear end of the outer wall of the rotating shaft, and a second fan blade is fixedly connected to the front end of the outer wall of the rotating shaft. The first fan blade is located inside the volute, and the second fan blade is located inside the disinfection chamber.

[0012] Furthermore, the drive source includes a motor located at the rear of the volute, the drive end of the motor being fixedly connected to the rear end of the rotating shaft, and the non-drive end of the motor being fixedly connected to the rear of the volute via a mounting bracket.

[0013] Furthermore, the dish cabinet includes a drain cabinet connected to the sterilization chamber via a slide rail. Multiple dish racks are fixedly connected to the top side of the drain cabinet, and multiple drain holes are provided on the bottom side of the drain cabinet.

[0014] Furthermore, an ultraviolet lamp is installed on the rear side of the inner wall of the disinfection chamber, and a drain pipe is fixedly connected to the bottom side of the disinfection chamber.

[0015] Furthermore, the bottom ends of both the oil drain pipe and the water drain pipe penetrate the bottom side of the chassis and are located inside the support frame.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, when fumes are being extracted, the oil and impurities in the fumes passing through the porous activated carbon accumulate inside the porous activated carbon, reducing the oil content in the fumes entering the volute. The oil flowing out of the porous activated carbon is then discharged through the oil drain pipe, preventing the accumulation of excessively oily fumes on the fan blades and affecting their rotational speed, thereby improving the efficiency of oil removal.

[0018] In this invention, when extracting cooking fumes, the rotating shaft can drive the second fan blade in the disinfection chamber to rotate simultaneously with the first fan blade, thereby accelerating the airflow in the disinfection chamber and quickly drying the dishes placed on the dish rack, thus increasing its practicality.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-3 One embodiment of this utility model provides: a gas stove exhaust structure, comprising:

[0030] The chassis 1 is divided into a disinfection chamber and an equipment chamber by a partition. The disinfection chamber is located in front of the equipment chamber. A gas stove 2 for cooking is installed on the top side of the chassis 1. The gas stove 2 is connected to a gas pipe. The disinfection chamber is equipped with multiple dish cabinets for storing cleaned dishes.

[0031] The smoke baffle 3 is used to reduce the spread of cooking fumes and prevent the fumes generated during cooking from drifting everywhere. The smoke baffle 3 is fixedly connected to the top rear end of the gas stove 2. The smoke baffle 3 has a cavity inside. A mesh plate 4 to prevent foreign objects from entering is fixedly connected to the front of the cavity. A volute 8 is fixedly connected to the inside of the equipment cavity. The cavity and the equipment cavity are connected by a fume duct and are connected to the volute 8. The volute 8 is equipped with a fan blade assembly driven by a drive source to simultaneously perform the rapid draining and fume extraction of dishes inside the dish cabinet.

[0032] Reference Figure 3 , Figure 4 and Figure 6 The fan blade assembly consists of a rotating shaft 10, fan blade 11, and fan blade 2 12. The front end of the rotating shaft 10, which is rotatably connected to the middle of the volute 8, passes through the front side of the outer wall of the volute 8 and the rear side of the inner wall of the disinfection chamber in sequence. Fan blade 11 is fixedly connected to the rear end of the outer wall of the rotating shaft 10, and fan blade 2 12 is fixedly connected to the front end of the outer wall of the rotating shaft 10. Fan blade 11 is located inside the volute 8, and fan blade 2 12 is located inside the disinfection chamber. The motor 9 located at the rear of the volute 8 serves as the driving source. Its driving end is fixedly connected to the rear end of the rotating shaft 10, and the non-driving end of the motor 9 is fixedly connected to the rear of the volute 8 through a fixing bracket.

[0033] Specifically, the motor 9 drives the rotating shaft 10 to rotate, which in turn drives the fan blades 11 and 12 fixed on the rotating shaft 10 to rotate simultaneously. In the process of extracting oil fumes, the fan blades 12 located in the disinfection chamber are also driven to rotate, thereby increasing the airflow in the disinfection chamber.

[0034] Reference Figure 2 and Figure 5 The fume duct consists of a filter chamber 7 and a smoke inlet pipe 6. The smoke inlet pipe 6 is fixedly connected to the input end of the filter chamber 7 located on the bottom side of the volute 8. The top end of the smoke inlet pipe 6 passes through the housing 1 and the gas stove 2 in sequence and is located inside the cavity. The filter chamber 7 is filled with porous activated carbon 13. The oil drain pipe 14 is fixedly connected to the bottom output end of the filter chamber 7. The input end of the volute 8 is fixedly connected to the top output end of the filter chamber 7. The output end of the volute 8 passes through the right side of the outer wall of the housing 1.

[0035] Specifically, activated carbon is an excellent adsorbent material, commonly used for filtering cooking fumes. Activated carbon effectively adsorbs odors and harmful substances in cooking fumes. Therefore, when cooking fumes pass through the porous activated carbon 13, oil and impurities accumulate inside the porous activated carbon 13. Through the loose, porous structure of the activated carbon 13, the oil accumulated inside flows out along the porous structure and to the bottom of the filter chamber 7. The rear cover of the casing 1 is removable, and the filter chamber 7 can also be disassembled, allowing the porous activated carbon 13 inside the filter chamber 7 to be replaced. When fumes are being drawn in, the motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the fan blade 11 to rotate inside the volute 8, which in turn creates a negative pressure inside the volute 8. This creates an attraction between the filter chamber 7 and the smoke inlet pipe 6, which are connected to the volute 8. The fumes from the boiler at the gas stove 2 are drawn into the cavity along the mesh plate 4, then into the smoke inlet pipe 6 and the filter chamber 7. In the filter chamber 7, the fumes are filtered by the porous activated carbon 13, reducing the content of oil and impurities in the fumes. The fumes then enter the volute 8 and are drawn out by the airflow inside the volute 8 through the output end of the volute 8. This prevents the accumulation of grease on the fan blade 11, which would affect the rotation speed of the fan blade 11, thereby improving the efficiency of grease treatment.

[0036] Reference Figure 6 The disinfection chamber is equipped with a dish cabinet consisting of a drain cabinet 15 connected to the disinfection chamber by a slide rail and multiple dish racks 16 fixedly connected to the top side of the drain cabinet 15. An ultraviolet lamp 17 is installed on the rear side of the inner wall. A drain pipe 18 is fixedly connected to the bottom side of the disinfection chamber. Multiple drain holes are opened on the bottom side of the drain cabinet 15. Ventilation holes are opened on both sides of the disinfection chamber.

[0037] Specifically, the curved structure of the dish rack 16 can hold the recessed part of the dish, thus fixing the dish on the dish rack 16 and allowing it to drain. The drained water will flow through the drain holes on the dish rack 16 to the bottom of the disinfection chamber, and the rotating fan blades 12 will accelerate the airflow in the disinfection chamber, allowing it to drain quickly. The dish can be disinfected by the irradiation of the ultraviolet lamp 17.

[0038] Reference Figure 7 The bottom ends of the oil drain pipe 14 and the drain pipe 18 both penetrate the bottom side of the casing 1 and are located inside the support frame 5.

[0039] Specifically, the support frame 5 has a through cavity to protect the oil drain pipe 14 and the drain pipe 18. The oil drain pipe 14 is used to drain the oil overflowing from the porous activated carbon 13 in the filter chamber 7 that filters the oil fumes. The drain pipe 18 is used to drain the water that drips from the wet dishes and falls into the bottom of the disinfection chamber through the drain hole of the drain cabinet 15.

[0040] Working principle: When the gas stove 2 is in operation, the synchronously started motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the fan blade 11 to rotate inside the volute 8, thereby creating a negative pressure inside the volute 8 and creating a suction force on the filter chamber 7 and the flue pipe 6 connected to the volute 8. This causes the oil fumes from the boiler at the gas stove 2 to enter the cavity along the mesh plate 4, and then enter the flue pipe 6 and the filter chamber 7. In the filter chamber 7, the fumes are filtered by the porous activated carbon 13, reducing the content of oil and impurities in the flue gas. Then, the fumes enter the volute 8 and are drawn out by the airflow inside the volute 8 through the output end of the volute 8. At the same time, the fan blade 12, which is also fixed on the rotating shaft 10, rotates in tandem with the fan blade 11, accelerating the airflow in the disinfection chamber and quickly drying the dishes placed on the dish rack 16.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
