Description

Technical Field

[0001] This utility model relates to the field of kitchenware and equipment technology, and more specifically to a dual-airflow smokeless baking pan. Background Technology

[0002] With the advancement of technology, the term "baking pan" is no longer exclusive to traditional baking pans. When used with an electric heating element, it can also be used as a roasting pan, offering multiple functions such as frying, grilling, and grilling. It can also be used in barbecue grills and air fryers.

[0003] The baking pan lacks a fume extraction device, resulting in a large amount of oil fumes being generated when users use it, causing inconvenience to users.

[0004] Therefore, in some existing baking pans, a single fan is used to achieve a closed-loop airflow path for blowing and smoking. The fan is located on one side inside the equipment, and the closed-loop airflow path is singular.

[0005] Furthermore, the airflow generated travels through a long duct path, resulting in insufficient blowing and smoke extraction power, thus failing to effectively eliminate smoke.

[0006] Meanwhile, existing technology products all have independent metal heat insulation plates and oil collection plates, which are complex in structure, have high product manufacturing costs, and are troublesome to clean and disassemble.

[0007] Moreover, existing technology products all have a left-side handle that holds the heating element and control box assembly, which disrupts the overall appearance of the product. Users must use both hands to operate the product, and the manufacturing cost is also high.

[0008] Moreover, in existing products, the heating element and the main housing are fixedly connected, which makes disassembly and assembly troublesome, thus affecting cleaning and maintenance. Utility Model Content

[0009] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dual-airflow smokeless grill pan. Its heating rod and control unit are placed on the main housing, which is easy to disassemble and separate, and convenient for maintenance. Moreover, it has a left guide fan and a right guide fan to improve its airflow and maximize the elimination of smoke generated during grilling. Its heat-insulating oil storage pan has heat insulation and oil storage functions, eliminating the need for a separate oil storage pan, which makes its manufacturing convenient.

[0010] The solution of this utility model to the aforementioned technical problem is:

[0011] A dual-airflow smokeless baking pan includes a main shell, the interior of which is a mounting cavity. The top surface of the mounting cavity extends beyond the top surface of the main shell. A left air guide fan and a right air guide fan are respectively installed on the lower left and right parts of the mounting cavity of the main shell.

[0012] A heat-insulating oil storage pan is installed on the upper part of the mounting cavity of the main shell.

The top surface of the partition plate portion has a groove extending downward. Sealing strips are fitted on the top surface of the partition plate portion, the other front and rear side walls of the groove, and the bottom surface. The wall panel of the oil reservoir portion is located in the groove. The outer wall surface of the front and rear wall panels of the oil reservoir portion is in close contact with the corresponding side wall surface of the corresponding sealing strip. The bottom surface of the bottom plate of the oil reservoir portion is pressed against the top surface of the bottom sealing strip. The partition plate portion and the oil reservoir portion divide the lower part of the mounting cavity into a left ventilation cavity and a right ventilation cavity.

[0018] The top surface of the bottom plate of the mounting cavity has vertically extending plates on both the left and right sides. The top of the two vertical plates has horizontally extending plates on both sides. The left or right end of the bottom plate of the corresponding mounting cavity has a side vertical baffle. The corresponding vertical plates, horizontal plates, side vertical baffles and the corresponding positions of the bottom plate of the mounting cavity form the fan mounting cavity. The left and right guide fans are located in the corresponding fan mounting cavities. The front and rear end plates of the left and right guide fans are fixed to the front and rear walls of the corresponding fan mounting cavities.

[0019] The bottom surface of the heating element is pressed against multiple horizontal support rods extending to the left and right. The two ends of the horizontal support rods are formed with downward bending parts. The horizontal support rods are fixed to the heating element by bending fixing pieces.

These embodiments are merely illustrative and are not intended to limit the scope of the present invention.

[0037] For example, see below. Figures 1 to 11 As shown, a dual-airflow smokeless baking pan includes a main shell 10. The interior of the main shell 10 is a mounting cavity. The top surface of the mounting cavity extends out of the top surface of the main shell 10. A left air guide fan 20 and a right air guide fan 30 are respectively installed on the lower left and right parts of the mounting cavity of the main shell 10. Multiple flow grooves are formed on the bottom plate and lower side wall of the main shell 10 between the left air guide fan 20 and the right air guide fan 30.

[0038] The top surface of the bottom plate of the mounting cavity has vertically extending plate portions 14 formed on both the left and right sides. The tops of the two vertically extending plate portions 14 have horizontally extending plate portions. The left or right end of the corresponding bottom plate of the mounting cavity has a side vertical baffle portion 15. The corresponding positions of the vertically extending plate portions 14, horizontally extending plate portions, side vertical baffle portions 15, and the bottom plate of the mounting cavity form the fan mounting cavity. The left guide fan 20 and the right guide fan 30 are located in their respective fan mounting cavities. The left guide fan... The front and rear end plates of the left and right guide fans 20 and 30 are fixed to the front and rear walls of the corresponding fan mounting cavities. The bottom plate of the mounting cavity directly below the left and right guide fans 20 and 30 is formed with a front-to-back disassembly groove. The lower cover plate covers the disassembly groove and is fixed to the bottom plate of the mounting cavity. The lower cover plate covers the corresponding disassembly groove, which allows the left or right guide fan 20 to be removed from the fan mounting cavity after the lower cover plate is opened. It can then be taken out from the disassembly groove, which is very convenient.

[0039] The right air inlet is formed on the right side of the housing of the right air guide fan 30. There is a ventilation channel between the right air inlet and the inner wall of the right side plate of the main housing 10. The right air outlet is formed on the left side of the housing of the right air guide fan 30. The right air outlet communicates with the right ventilation cavity at the bottom of the main housing 10. The left air inlet is formed on the right side of the housing of the left air guide fan 20. The left air inlet communicates with the left ventilation cavity at the bottom of the main housing 10. The left air outlet is formed on the left side of the housing of the left air guide fan 20. There is a ventilation channel between the left air outlet and the inner wall of the left side plate of the main housing 10.

[0040] Multiple left ventilation slots are formed on the vertical plate 14 on the left side. The left ventilation slots are connected to the left air inlet of the left guide fan 20 and to the left ventilation cavity. Multiple right ventilation slots are formed on the vertical plate 14 on the right side. The right ventilation slots are connected to the right air outlet of the right guide fan 30 and to the right ventilation cavity.

[0041] Furthermore, a heat-insulating oil storage pan 40 is installed on the upper part of the mounting cavity of the main housing 10. Multiple ventilation holes 49 are formed on the upper part of the left and right side plates of the heat-insulating oil storage pan 40, and the ventilation holes 49 are connected to the corresponding ventilation channels.

[0042] A heating element 50 is placed on the top surface of the bottom plate of the heat-insulated oil storage pan 40, and a barbecue plate 60 is placed on the top surface of the heating element 50.

[0043] Furthermore, a control unit 70 is fixed to the front of the heating element 50. The heating element 50 is electrically connected to the control main board in the control unit 70 (the internal structure of the control unit is basically the same as that of the control unit used in conventional baking pans, and is a conventional structure, which will not be described in detail here; its connection structure with the heating element 50 is also a conventional method and structure, which will not be described in detail here). The front end of the heating element 50 is fixed to the control unit 70, and the control unit 70 is inserted into a downwardly extending central groove formed in the middle of the top surface of the front wall panel of the main housing 10. The connection part between the heating element 50 and the control unit 70 is inserted into a downwardly extending groove formed in the middle of the top surface of the front wall panel of the heat-insulating oil storage pan 40. The front wall surface of the control unit 70 does not extend beyond the front end of the corresponding groove.

[0044] The bottom surface of the central groove has a downwardly extending positioning recess 11, and the bottom surface of the control host 70 has a downwardly extending positioning protrusion 71, which is inserted into the positioning recess 11. Multiple rear heat dissipation holes are formed on the rear wall of the positioning recess 11, and the positioning protrusion 71 cooperates with the positioning recess 11. The front side wall of the control host 70 has a rearwardly extending elongated grip groove 72. This allows a hand to be inserted into the elongated grip groove 72 to hold the control host 70, allowing it to be removed or placed. No other parts of the outer wall of the control host 70 protrude outwards, ensuring the integrity of the entire device, resulting in a more aesthetically pleasing appearance and reducing external space occupation.

[0045] Furthermore, a radially extending edge 12 is formed on the top inner wall of the mounting cavity, and a protruding support portion is formed at the front and rear of the radially extending edge 12 on the left and right sides. A bent support edge 41 extending outward horizontally is formed on the upper part of the left and right side plates of the heat insulation oil storage pan 40, and the bent support edge 41 presses against the top surface of the corresponding two protruding support portions on the left or right.

[0046] The bottom plate of the heat-insulated oil storage pan 40 has an oil storage groove 42 that extends downward and protrudes downward in the middle of its top surface.

[0047] Furthermore, the bottom surface of the mounting cavity of the main housing 10 is formed with a partition plate portion 13 extending forward and backward and upward. The front and rear ends of the partition plate portion 13 are formed on the front and rear inner walls of the mounting cavity. The top surface of the partition plate portion 13 is formed with a downward extending groove. Sealing strips are fitted on the top surface of the partition plate portion 13, the other front and rear side walls of the groove, and the bottom surface. The wall panel at the oil storage tank portion 42 is located in the groove, and the outer wall surfaces of the front and rear wall panels at the oil storage tank portion 42 are in close contact with the corresponding sealing strips. On the corresponding side wall, the bottom surface of the bottom plate of the oil storage tank 42 presses against the top surface of the bottom sealing strip, and the bottom surfaces of the front and rear parts of the bottom plate of the heat-insulating oil storage pan 40 press against the top surface of the sealing strip on the top surface of the partition plate 13; the partition plate 13 and the oil storage tank 42 divide the lower part of the mounting cavity into a left ventilation cavity and a right ventilation cavity, that is, the partition plate 13 and the bottom surface of the heat-insulating oil storage pan 40 form a closed cavity to isolate the airflow path generated by the left guide fan 20 and the right guide fan 30.

[0048] Furthermore, the top surface of the horizontal plate is formed with a plurality of front-to-back extended protruding support strips 150, and the bottom surface of the heat-insulating oil storage pan 40 presses against the top surface of all the protruding support strips 150.

[0049] The bottom surface of the heating tube 50 is pressed against one or more horizontal support rods 51 extending to the left and right. Both ends of the horizontal support rods 51 are formed with downward bending portions. The horizontal support rods 51 are fixed to the heating tube 50 by bending fixing pieces. The bottom end of the bending portion is pressed against the top surface of the bottom plate of the heat insulation oil storage pan 40.

[0050] The bottom surface of the grill plate 60 has a protrusion 61 formed in the center to mate with the heating element 50. The bottom surface of the protrusion 61 has a recessed groove to mate with the heating element 50. The corresponding part of the heating element 50 is inserted into a corresponding elongated slot, and the top surface of the corresponding part of the heating element 50 presses against the top surface of the corresponding elongated slot. This structure results in a large contact area between the heating element 50 and the grill plate 60, greatly improving heating efficiency and heating effect.

[0051] The grill plate 60 has grips fixed to both the front and rear of its top surface for easy handling.

[0052] Furthermore, the bottom surface of the main housing 10 is fixed with support pads at the front and rear left and right ends of the bottom plate.

[0053] In this embodiment, both the left guide fan 20 and the right guide fan 30 are cross-flow fans that extend forward and backward. They can generate higher flow and pressure with the same power consumption, thereby effectively saving energy.

[0054] In this embodiment, the main body of the heating tube 50 is S-shaped and coiled, thereby setting a sufficiently long tube body within a limited range to improve the heating effect.

[0055] In this embodiment, filter cotton blocks (not shown in the attached drawings) are filled into the right ventilation cavity so that they cover the right air outlet of the right air guide fan 30.

[0056] The control host 70 has a power cord connection socket on its front wall. When in use, one end of the power cord is inserted into the power cord connection socket and the other end is inserted into the socket to enable power supply and control the operation of the control host 70.

[0057] Then, the left guide fan 20 and the right guide fan 30 are turned on simultaneously. At this time, the left guide fan 20 draws the cold air below the main housing 10 into the left ventilation cavity through the flow channel below the left ventilation cavity. Then, it enters the left guide fan 20 through the left air inlet and is discharged from the left air outlet of the left guide fan 20, entering the left ventilation channel. It is then discharged through multiple ventilation holes 49 on the upper part of the left side plate of the heat-insulating oil storage pan 40, blowing air onto the top of the grill plate 60. The grill plate 60 is filled with food, which is heated by the heating tube 50 at the bottom to achieve grilling. The smoke generated by grilling is blown to the right along with the gas discharged from the multiple ventilation holes 49 on the upper part of the left side plate of the heat-insulating oil storage pan 40. The right air guide fan 30 is running at this time. The suction force of the right air inlet of the right air guide fan 30 causes the smoke generated by the barbecue to be blown to the right by the wind on the left. At this time, it is attracted by the suction force of the right air inlet of the right air guide fan 30, and thus enters the right ventilation channel through the multiple ventilation holes 49 on the upper part of the right side plate of the heat insulation oil storage tray 40, and then enters the right air inlet of the right air guide fan 30. Then, it is blown from the right air outlet to the filter cotton block, which adsorbs and filters the oil and other particulate matter in the smoke. The filtered air is discharged from the flow channel below the right ventilation cavity. After each use, the barbecue plate 60, heating element 50, control host 70 and heat insulation oil storage tray 40 need to be removed from the main housing 10 and the filter cotton block needs to be replaced, which is very convenient.

[0058] In this embodiment, the heating rod 50 and the control host 70 are placed on the main housing 10. They can be disassembled and separated simply by lifting the heating rod 50 and the control host 70. This makes operation convenient and maintenance easy. In addition, the left air guide fan 20 and the right air guide fan 30 can improve the airflow and achieve air circulation, thereby maximizing the elimination of smoke generated during the grilling process.

[0059] Its heat-insulating oil storage tray 40 has heat insulation and oil storage functions. The top surface of its bottom plate has a downward-extending oil storage groove 42 formed in the middle, so that the oil on the grill plate 60 can flow along the inner side wall of the heat-insulating oil storage tray 40 into the oil storage groove 42 for collection during grilling. It does not need to set up a separate oil storage tray, which makes it easy to manufacture and greatly reduces manufacturing costs and difficulties.

[0060] Its heating element 40 has a horizontal support rod 51 directly installed at the bottom for support, eliminating the need for a support frame and reducing manufacturing costs.

[0061] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
