Description

Technical Field

[0001] This invention relates to the field of cooking appliance technology, specifically to a gas-fired cooking device. Background Technology

[0002] Gas cooking is a cooking method that uses the combustion of gas to provide heat to food, and is generally achieved by heating the cooking appliance components through a gas stove.

[0003] Chinese utility model patent CN218606239U discloses a multifunctional outdoor cooking appliance, including a worktable. The worktable is equipped with at least one housing assembly, at least one combustion assembly, and at least one set of hot air assemblies. The housing assembly includes an upper housing and a lower housing. The hot air assembly is disposed on the upper housing, and a baking tray and the combustion assembly are disposed inside the lower housing. The hot air assembly is positioned above the baking tray, and the combustion assembly is positioned below the baking tray. The hot air assembly blows hot air onto the food on the baking tray. Through the cooperation of the hot air assembly and the combustion assembly, the upper and lower surfaces of the food are heated separately.

[0004] In the aforementioned prior art, the hot air assembly is located above the baking pan, meaning the motor of the hot air assembly is located at the top of the upper housing. During cooking, because hot air has a low density and rises easily, a large amount of heat accumulates at the top of the upper housing, close to the motor's installation space, causing the motor to overheat severely. In addition, the combustion assembly directly heats the bottom of the baking pan with an open flame, and the food bottom is in contact with the bottom of the baking pan, resulting in high heat and rapid cooking. In contrast, the upper part of the food receives insufficient heat, easily leading to the problem of the bottom burning while the top remains uncooked. Utility Model Content

[0005] This invention addresses the existing technical problems by providing a gas-fired cooking device that improves the heating of the motor.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A gas cooking device includes a shell and a furnace body located inside the shell, a cover assembly that opens and closes on the furnace body, and a cooking utensil assembly. A gas burner is disposed inside the furnace body and located below the cooking utensil assembly. The cover assembly and the cooking utensil assembly form a cooking cavity inside the furnace body. The cooking utensil assembly and the gas burner form a heating cavity inside the furnace body. The cooking cavity and the heating cavity are connected by a connecting hole. An air circulation assembly is disposed on one side of the furnace body. The air circulation assembly includes a first fan blade and a motor that drives the first fan blade to rotate. The connecting hole is disposed away from the open flame area of ​​the gas burner and is located on the airflow circulation path formed by the air circulation assembly. The motor drives the first fan blade to rotate, so that the airflow entering the cooking cavity from the connecting hole circulates, thereby providing auxiliary heating for the food in the cooking cavity.

[0007] The beneficial effects of this invention are as follows: First, hot air expands and tends to rise, accumulating in the top area of ​​the cooking cavity. In this design, the air circulation component is located on one side of the oven cavity body, avoiding the area where hot air accumulates and reducing its impact on the motor, thus improving the motor's heating performance. Secondly, side blowing creates a higher wind speed above the cooking appliance components and a lower wind speed below them. The lower pressure in the high-speed area accelerates the entry of hot air below the cooking appliance components into the cooking cavity, increasing the efficiency of heat entry and thus improving heat circulation efficiency. Furthermore, the connecting hole transports heat into the cooking cavity, reducing heat accumulation and circulating the heat entering the cavity to heat the upper surface of the food. Compared to existing technologies, this invention improves the motor's heating performance and accelerates heat exchange and circulation, increasing the heating uniformity of both the upper and lower surfaces of the food. Additionally, regardless of the depth or size of the cooking vessel, the distance between the first fan blade and the food remains constant; a smaller distance results in better airflow circulation to the upper surface of the food, improving heat utilization and reducing energy loss.

[0008] Furthermore, the cooking utensil assembly includes a cooking vessel, and the communicating holes are multiple holes formed on the cooking vessel.

[0009] Using the above technical solution, hot air is transferred through the connecting hole. Since hot air rises, it can easily enter the cooking cavity through the connecting hole. On the other hand, the high wind speed area in the cooking cavity caused by the air circulation component is close to the low wind speed area in the heating cavity, which can maximize the effect of heat transfer brought about by the pressure difference and improve heat transfer efficiency under the condition of using the same air circulation component and gas stove head.

[0010] When the connecting hole is positioned away from the gas stove head, it can also be used as an oil drain hole, serving the dual functions of oil leakage and heat transmission.

[0011] Furthermore, the cooking appliance assembly includes a cooking vessel and a support for placing the cooking vessel. The support is a bracket with an annular support surface, which surrounds the gas stove head and is located above the gas stove head. The cooking vessel is placed on the annular support surface, and a connecting hole is provided on the annular support surface and located around the periphery of the cooking vessel.

[0012] By adopting the above technical solution, the connecting hole is located on the support component, which is far away from the open flame area of ​​the gas stove. This reduces the impact of airflow on the flame, improves the stability of the gas stove flame, meets the needs of hot air circulation, and forms a cooking chamber with high wind speed and a heating chamber with low wind speed, thus accelerating the entry of hot air into the cooking chamber.

[0013] Furthermore, the cooking utensil assembly includes a cooking vessel with multiple notches on its outer wall, and a gap between the cooking vessel and the oven cavity body, with the connecting hole formed by the gap between the two.

[0014] By adopting the above technical solution, the connection port is located on the periphery of the cooking vessel, which reduces the impact of airflow on the flame, improves the stability of the gas stove flame, meets the needs of hot air circulation, and forms a cooking chamber with high wind speed and a heating chamber with low wind speed, accelerating the entry of hot air into the cooking chamber.

[0015] Furthermore, the air circulation assembly is located on the rear side of the furnace cavity body.

[0016] By adopting the above technical solution, the rear side is far away from the operating side, and the displacement of the rear side is small when opening and closing the cover assembly, making it easier to open and close the cover. In addition, it is easier to set up an installation area on the rear side, ensuring a uniform distribution in the center while maintaining a lightweight appearance, and reducing the occurrence of the cover tipping over after opening.

[0017] Furthermore, the first fan blade is a cross-flow fan blade horizontally placed on the rear side of the oven cavity body. The cross-flow fan blade is arranged around the motor shaft. The rear side wall of the oven cavity body or cover assembly is provided with an air outlet and a return air hole. The air outlet is located on the left and right sides of the cross-flow fan blade, and the return air hole is set at the center of the cross-flow fan blade. The motor drives the first fan blade to rotate, and the air enters the cooking cavity from the air outlet, runs forward to the front side of the oven cavity body, and turns back from the center to the return air hole after encountering the front side wall of the oven cavity body. The connecting hole is located on both sides of the cross-flow fan blade and is set corresponding to the air outlet.

[0018] By adopting the above technical solution, the cross-flow fan blades discharge air from the periphery and return air from the axial direction, forming an airflow circulation. Combined with the air outlet and return air vents, this improves the regularity of the airflow and enhances the effectiveness of heat circulation. With the connecting hole corresponding to the air outlet, the wind speed difference between the cooking chamber and the heating chamber directly acts on the connecting hole, significantly accelerating the rate at which hot air enters the cooking chamber. Once the hot air from the heating chamber enters the cooking chamber, it directly participates in the air circulation within the cooking chamber, allowing the hot air to quickly act on the food surface.

[0019] Furthermore, the first fan blade is a centrifugal fan blade, and a guide shroud is provided around the centrifugal fan blade so that the circulating airflow exits from the outside of the centrifugal fan blade and returns from the center of the centrifugal fan blade; the connecting hole is located on the airflow circulation path.

[0020] Using the above technical solution, the centrifugal fan drives the airflow to circulate in the cooking chamber, and some of the hot air in the heating chamber enters the cooking chamber through the connecting hole and directly participates in the airflow circulation in the cooking chamber.

[0021] Furthermore, the cover assembly includes a lower housing with an opening at the lower end and an upper housing. The upper housing is fastened to the outside of the lower housing to form a receiving cavity. The first fan blade is located inside the receiving cavity, and the motor is located outside the upper housing. The motor shaft passes through the side wall of the upper housing and extends into the receiving cavity to connect with the first fan blade.

[0022] By adopting the above technical solution, the first fan blade will not be directly exposed to the outside when the cover assembly is opened, thus improving the safety of the equipment. At the same time, the holes in specific positions on the lower housing can further regulate the airflow circulation direction and improve the effectiveness and orderliness of heat flow circulation.

[0023] Furthermore, the cover assembly is provided with a hot air outlet, which is located on the rear side of the top of the cover assembly.

[0024] By adopting the above technical solution, the hot air outlet will expel excess heat and moisture from the cooking cavity, ensuring a balance of internal and external air pressure; when the hot air outlet is located on the rear side, it is far away from the operating side, improving the safety of the equipment.

[0025] Furthermore, a collection box is provided on the furnace cavity body to collect the liquid flowing down after the cover assembly is opened.

[0026] By adopting the above technical solution, water and grease on the cover components can be avoided from contaminating the outer shell, making it easy to clean. Attached Figure Description

Detailed Implementation

[0037] In the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0039] like Figure 1-2 As shown, this invention discloses a gas cooking device, including a housing, a furnace body 2 located within the housing 1, a cover assembly 3 that opens and closes on the furnace body 2, a cooking utensil assembly 4, a gas burner 5 located below the cooking utensil assembly 4, and an air circulation assembly 9. The gas burner 5 is located within the furnace body 2 and is connected to a gas pipe, one end of which extends into the housing 1 for transporting gas.

[0040] The cooking appliance assembly 4 includes a cooking dish 41, which can be a baking pan, frying basket, rotisserie, etc. In this embodiment, a baking pan is used. The gas stove head 5 is located directly below the baking pan and provides open flame heating for the cooking appliance assembly 4. In other embodiments, other heating positions can be used. The cooking dish 41 and the cover assembly 3 form a cooking cavity 6, and the cooking dish 41 and the gas stove head 5 form a heating cavity 7 within the oven cavity body 2. The cooking cavity 6 and the heating cavity 7 are connected by a connecting hole 8. Specifically, the oven cavity body 2 includes a heat-insulating inner liner 22, and the gas stove is located within the heat-insulating inner liner 22.

[0041] The air circulation assembly 9 is located on one side of the furnace cavity body 2. In this embodiment, the air circulation assembly 9 is located on the rear side of the furnace cavity body 2. The air circulation assembly 9 includes a first fan blade 91 and a motor 92. The first fan blade 91 can be a centrifugal fan blade, a cross-flow fan blade, or an axial flow fan blade, etc., which can play a role in agitating air. In this embodiment, the first fan blade 91 is a cross-flow fan blade.

[0042] Hot air expands and tends to rise, accumulating at the top of the cooking cavity 6. In this design, the air circulation component 9 is positioned on one side of the oven cavity body 2, avoiding this hot air accumulation area and reducing its impact on the motor 92, thus improving the motor's heating performance. Furthermore, the side-blowing design creates a higher airflow velocity above the cooking appliance component 4 and a lower airflow velocity below it. The lower pressure in the high-velocity area accelerates the entry of hot air below the cooking appliance component 4 into the cooking cavity 6, increasing the efficiency of heat transfer and thus improving heat circulation efficiency. Compared to existing technologies, this design improves both the heating performance of the motor 92 and accelerates heat exchange and circulation.

[0043] The cover assembly 3 includes a lower housing 321 with an opening at the lower end and an upper housing 311. The upper housing 311 is fastened to the rear side wall of the lower housing 321 to form a receiving cavity 34. A first fan blade 91 is located inside the receiving cavity 34. A motor 92 is located outside the upper housing 311. The shaft of the motor 92 passes through the side wall of the upper housing 311 and extends into the receiving cavity 34 to connect with the first fan blade 91. An air outlet 93 and a return air outlet 94 are provided on the rear side wall of the lower housing 321 to connect the cooking cavity 6 and the receiving cavity 34. The air outlet 93 is located on the left and right sides of the cross-flow fan blade, and the return air outlet 94 is located at the center of the cross-flow fan blade. The motor 92 drives the first fan blade 91 to rotate. Air enters the cooking cavity 6 from the air outlet 93, runs forward to the front side of the oven cavity body 2, and turns back from the center to the return air outlet 94 after encountering the front side wall of the oven cavity body 2.

[0044] The air circulation assembly 9 also includes a second fan blade 95 for cooling the motor 92. Specifically, the upper housing 311 includes two parts: a first housing 311 and a second housing 312. The first housing 311 is fastened to the outer wall of the lower housing 321, and the second housing 312 is fastened to the outer wall of the first housing 311. The first fan blade 91 is located between the first housing 311 and the lower housing 321, and the motor 92 and the second fan blade 95 are located between the second housing 312 and the first housing 311. Air vents are provided on the side wall of the second housing 312 away from the first housing 311 for allowing cool air to enter and cool the motor 92.

[0045] A connecting hole 8 is provided on the cooking vessel 41. Specifically, the connecting hole 8 is located on the outside of the gas stove. An oil drip tray 21 is provided inside the heat-insulating inner liner 22 of the furnace body 2. The oil drip tray 21 is located on the outside of the gas stove and below the connecting hole 8, with clearance space provided at the location of the gas pipe. The cooking vessel 41 is placed on top of the oil drip tray 21 or the heat-insulating inner liner 22.

[0046] During cooking, water and oil flow downwards from the connecting hole 8 into the oil receiving tray 21, while hot air from the heating chamber 7 enters the cooking chamber 6. The connecting hole 8 can also serve as an oil drain hole. Hot air is transferred through the connecting hole 8; since hot air rises, it can easily enter the cooking chamber 6 through the connecting hole 8. Furthermore, the high-speed zone in the cooking chamber 6 created by the air circulation component 9 is adjacent to the low-speed zone in the heating chamber 7, maximizing the heat transfer effect caused by the pressure difference. This improves heat transfer efficiency when using the same air circulation component 9 and gas burner 5.

[0047] Furthermore, the connecting hole 8 is located on the outside of the gas stove. In this embodiment, the connecting holes 8 are evenly distributed on the outer edge area of ​​the cooking vessel 41, and the connecting holes 8 are located corresponding to the positions of the air outlet 93. The wind speed difference between the cooking chamber 6 and the heating chamber 7 directly acts on the connecting hole 8, which can greatly accelerate the rate at which hot air enters the cooking chamber 6. After the hot air from the heating chamber 7 enters the cooking chamber 6, it directly participates in the air circulation within the cooking chamber 6, allowing the hot air to quickly act on the food surface.

[0048] Furthermore, a guide plate is provided on the first housing 311 at the position corresponding to the air outlet 93, extending obliquely from the side of the air outlet away from the return air outlet to the side of the air outlet closer to the return air outlet, and the guide plate extends obliquely away from the side of the lower housing 321.

[0049] Furthermore, a hot air outlet 33 is provided on the rear side of the top of the lower housing 321. When the gas stove head 5 and the air circulation assembly 9 are running, excess hot air overflows from the hot air outlet 33. When the hot air outlet 33 is located on the rear side, it is away from the operating side, which improves the safety of the equipment.

[0050] In addition, the cover assembly 3 can be a movable connection of placement type or a rotating connection of hinge type to realize the opening and closing connection with the furnace cavity body 2. In this embodiment, a hinge is used.

[0051] Furthermore, the rear side of the housing 1 extends to the outside of the cover assembly 3. The top of the housing 1 is provided with a groove corresponding to the position of the air circulation assembly 9. A collection box 10 is placed in the groove. When the cover assembly 3 is opened, water and grease flow down the lower housing 321 into the collection box 10 to avoid secondary pollution.

[0052] The working principle of the above implementation is as follows: the cover assembly 3 is closed, the gas stove is ignited, and the air circulation assembly 9 is activated. The air temperature in the heating chamber 7 rises. Due to the wind speed difference between the cooking chamber 6 and the heating chamber 7, the hot air enters the cooking chamber 6 from the heating chamber 7 and immediately participates in the hot air circulation, distributing the heat accumulated in the baking pan and the heating chamber 7 as much as possible throughout the entire cooking chamber 6 and heating chamber 7, improving the all-round heating effect on the food, while reducing the heat on the motor 92.

[0053] Example 2:

[0054] A gas-fired cooking appliance differs from Embodiment 1 in that:

[0055] like Figure 3 As shown, the cooking appliance assembly 4 includes a support 42 and a cooking dish 41. The support 42 is a bracket with an annular support surface, which surrounds the gas burner 5 and is located above the gas burner 5. The cooking dish 41 is placed on the support 42, and a connecting hole 8 is provided on the annular support surface of the support 42 and is located around the cooking dish 41.

[0056] The connecting hole 8 is located on the support 42 and is far away from the open flame area of ​​the gas stove, which reduces the impact of airflow on the flame, improves the stability of the gas stove flame, meets the needs of hot air circulation, and forms a cooking chamber 6 with high wind speed and a heating chamber 7 with low wind speed, accelerating the entry of hot air into the cooking chamber 6.

[0057] The working principle of the above implementation is as follows: the cover assembly 3 is closed, the gas stove is ignited, and the air circulation assembly 9 is activated. The air temperature inside the heating chamber 7 rises. Due to the wind speed difference between the cooking chamber 6 and the heating chamber 7, the hot air enters the cooking chamber 6 from the heating chamber 7 through the connecting hole 8 and gradually participates in the hot air circulation. This distributes the heat accumulated in the baking pan and the heating chamber 7 as much as possible throughout the entire cooking chamber 6 and the heating chamber 7, improving the all-round heating effect on the food while reducing the heat on the motor 92.

[0058] Example 3:

[0059] A gas-fired cooking appliance differs from Embodiment 1 in that:

[0060] like Figure 4 As shown, the outer wall of the cooking vessel 41 extends inward to form multiple notches 411. There is a gap between the bottom of the cooking vessel 41 and the oven cavity body 2. The gaps and notches 411 form a connecting hole 8. The connecting hole is located on the periphery of the cooking vessel 41, which reduces the possible impact of airflow on the flame, improves the stability of the gas stove flame, and meets the needs of hot air circulation. At the same time, it forms a cooking cavity 6 with high wind speed and a heating cavity 7 with low wind speed, accelerating the entry of hot air into the cooking cavity 6.

[0061] The working principle of the above implementation method is as follows: the cooking dish 41 is placed on the heat-insulating inner liner 22, the lid assembly 3 is closed, the gas stove is ignited, and the air circulation assembly 9 is activated. The air temperature in the heating chamber 7 rises. Due to the wind speed difference between the cooking chamber 6 and the heating chamber 7, the hot air enters the cooking chamber 6 from the heating chamber 7 through the connecting hole 8 and gradually participates in the hot air circulation, distributing the heat accumulated in the baking pan and the heating chamber 7 as much as possible throughout the entire cooking chamber 6 and heating chamber 7, improving the all-round heating effect on the food, while reducing the heat on the motor 92.

[0062] Example 4:

[0063] A gas-fired cooking appliance differs from Embodiment 1 in that:

[0064] like Figure 5 As shown, the lower surface of the cooking vessel 41 extends downward to form multiple support feet 412, and a connecting hole 8 is formed between adjacent support feet 412. The connecting hole is located on the periphery of the cooking vessel 41, which reduces the possible impact of airflow on the flame, improves the stability of the gas stove flame, meets the needs of hot air circulation, and forms a cooking chamber 6 with high wind speed and a heating chamber 7 with low wind speed, accelerating the entry of hot air into the cooking chamber 6.

[0065] The working principle of the above implementation method is as follows: the cooking dish 41 is placed on the heat-insulating inner liner 22, the lid assembly 3 is closed, the gas stove is ignited, and the air circulation assembly 9 is activated. The air temperature in the heating chamber 7 rises. Due to the wind speed difference between the cooking chamber 6 and the heating chamber 7, the hot air enters the cooking chamber 6 from the heating chamber 7 through the connecting hole 8 and gradually participates in the hot air circulation, distributing the heat accumulated in the baking pan and the heating chamber 7 as much as possible throughout the entire cooking chamber 6 and heating chamber 7, improving the all-round heating effect on the food, while reducing the heat on the motor 92.

[0066] Example 5:

[0067] A gas-fired cooking appliance, differing from Embodiment 1 in that the air circulation component 9 is located on the left or right side of the cover component 3.

[0068] Example 6:

[0069] A gas-fired cooking appliance differs from Embodiment 1 in that:

[0070] The centrifugal fan blade is surrounded by a guide shroud 43, which is the first housing 311. This allows the circulating airflow to exit from the air outlet 93 on the outside of the centrifugal fan blade and return from the air return hole 94 in the center of the centrifugal fan blade. The connecting hole 8 is located on the airflow circulation path.

[0071] Example 7:

[0072] A gas-fired cooking appliance differs from Embodiment 1 in that:

[0073] like Figure 6 As shown, the first fan blade 91 is an axial flow fan blade, and only air outlet holes 93 are opened on the rear side wall of the lower housing 321. The air outlet holes 93 are evenly distributed in the area covered by the accommodating cavity 34. After the axial flow fan blade is started, it is used to stir the airflow in the cooking cavity 6.

[0074] Example 8:

[0075] A gas-fired cooking appliance differs from Embodiment 1 in that:

[0076] like Figure 7 As shown, the first fan blade 91 is located inside the cooking cavity 6, the second fan blade 95 and the motor 92 are located inside the accommodating cavity 34, and the motor 92 shaft extends through the lower housing 321 into the cooking cavity and connects with the first fan blade 91.

[0077] Example 9:

[0078] A gas-fired cooking appliance differs from Embodiment 1 in that the air circulation component 9 is positioned differently, and the cover component 3 consists only of a lower housing 32.

[0079] like Figure 8 As shown, the air circulation assembly 9 is located on the rear side of the furnace body 2. The rear side of the housing 1 extends upward to the area where the cover assembly 3 is located, and the air circulation assembly 9 is located in this area. In this way, opening and closing the cover assembly 3 is easier, reducing the possibility of movement of the air circulation assembly 9 and ensuring the installation stability of the air circulation assembly 9 on the equipment.

[0080] A first outer cover and a second outer cover are arranged sequentially on the outer side of the housing 1. A first fan blade 91 is arranged between the first outer cover and the housing 1. An air outlet 93 and an air return 94 are opened on the rear side wall of the first outer cover. A second fan blade 95 and a motor 92 are arranged between the first outer cover and the second outer cover.

[0081] Example 10:

[0082] A gas-fired cooking appliance, such as Figure 9 As shown, the difference from Embodiment 1 is that the first fan blade 91 is located in the cooking cavity 6, and the second fan blade 95 and the motor 92 are located in the accommodating cavity 34.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
