Description

Technical Field

[0001] This utility model belongs to the field of stir-frying technology, and in particular relates to a stir-frying device. Background Technology

[0002] Stir-frying involves stir-frying ingredients at high temperatures. To improve the stir-frying effect, automated machines are now widely used instead of traditional manual methods. Machine-stirred ingredients not only produce better results but also avoid the harmful effects of oil fumes and high temperatures on the human body.

[0003] Currently, machine-based roasting is mostly done using roasting machines. The main structure of a roasting machine includes the main unit, a roasting pan mounted on the main unit, and a motor and roasting rack for roasting. A discharge port is also provided on the roasting machine, which is sealed using a valve plate. Once roasting is complete, the valve plate is opened to release the material.

[0004] In actual frying processes, a large amount of oil fumes are generated during the frying process. Therefore, existing technology uses an exhaust fan installed above the frying machine to extract the fumes. Furthermore, to facilitate adding ingredients during frying, the exhaust hood is kept at a sufficient distance from the frying machine for easy operation. However, the drawback is that the amount of oil fumes generated during frying, especially at high temperatures, is very large. Because of the need to easily add ingredients to the frying machine, the exhaust hood maintains a certain operating height relative to the frying machine. This means that when the amount of oil fumes is very high, the significant height difference between the exhaust hood and the frying machine prevents a large amount of fumes from being extracted in time, causing the fumes to diffuse into the workshop.

[0005] Furthermore, during the stir-frying process, a large amount of oil fumes adhere to the side walls of the exhaust hood. After stir-frying, the high-temperature oil fumes form oil stains and droplets on the side walls of the exhaust hood. Currently, the exhaust hood is unable to collect the oil stains, resulting in no oil dripping into the pot during the stir-frying process, causing contamination. This is especially true for exhaust hoods that have not been cleaned for a long time. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a stir-frying device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A stir-frying device includes a stir-frying machine body, which includes a stir-frying machine and a wok installed on the stir-frying machine; it also includes an oil fume extraction mechanism that cooperates with the stir-frying machine body.

[0009] The smoke extraction mechanism includes an adjustable exhaust hood, the top of which is connected to a spring tube, which is connected to an external exhaust duct.

[0010] An oil collection tank structure is installed inside the exhaust hood, through which the sludge oil adhering to the inner wall of the exhaust hood is collected.

[0011] Preferably, the exhaust hood adjusts its angle through an angle adjustment structure, which includes brackets fixedly installed on both sides of the top of the stir-fry machine. The exhaust hood is rotatably connected between the brackets, and a motor that drives the exhaust hood to rotate and adjust its angle is installed on one side of the bracket.

[0012] Preferably, the oil collection tank structure includes an oil collection tank that can be detachably installed inside the exhaust hood, and the oil collection tank has an oil collection cavity inside;

[0013] The oil collection tank has an annular oil inlet that connects to the oil collection chamber on one side of the inner wall of the exhaust hood.

[0014] The bottom of the oil collection tank is equipped with several oil discharge structures.

[0015] Preferably, the oil draining structure includes an oil draining threaded hole formed on the oil collection tank, and a sealing bolt is threadedly connected to the oil draining threaded hole.

[0016] Preferably, the stir-frying device further includes a stir-frying rack mechanism, which includes a stir-frying rack structure disposed inside the wok;

[0017] It also includes a motor bracket installed on the top of the stir-fry machine, on which the stir-fry motor is mounted;

[0018] The output end of the stir-fry motor is fixedly installed with a stir-fry rack structure.

[0019] Preferably, the stir-fry rack structure includes a base, and a plurality of arc-shaped stir-fry racks are installed on the outer side wall of the base; a drive shaft is fixedly installed at the top center of the base, and the output shaft of the stir-fry motor is fixedly installed on the drive shaft.

[0020] Preferably, the angle of the arc-shaped wok rack is adjusted by a flip-adjustment structure;

[0021] The flip-adjustment structure includes a hinge interface on the outer wall of the base, and the lower end of the arc-shaped wok rack is hinged to the hinge interface.

[0022] The flipping adjustment structure also includes an adjustment slide block slidably connected to the drive shaft, and a tension steel cable is fixedly installed between the adjustment slide block and the top of the arc-shaped wok rack;

[0023] A pair of nuts, positioned at the top and bottom of the adjusting slide, are threaded onto the drive shaft. After the lifting and adjusting slide is adjusted, the arc-shaped stir-fry rack flips to adjust the stir-frying posture.

[0024] Preferably, the top of the arc-shaped stir-fry rack is hinged with a hanging ring, and the lower end of the pulling steel cable is fixedly connected to the hanging ring.

[0025] Preferably, the arc-shaped wok rack is made of steel.

[0026] This utility model has the following beneficial effects:

[0027] 1. The smoke extraction mechanism includes an adjustable exhaust hood. During normal cooking, the exhaust hood covers the wok with a small gap between it and the wok, serving not only to extract smoke but also to cover the wok (preventing dust from entering).

[0028] Lowering the distance between the exhaust hood and the wok makes it difficult to add ingredients due to the obstruction of the exhaust hood. Therefore, this invention designs the exhaust hood to be rotatable. Once ingredients are added, the exhaust hood is rotated, increasing the distance between one side of the exhaust hood and the wok, making it easier to add ingredients.

[0029] 2. During operation, when the exhaust hood has been used for a long time, a large amount of oil will accumulate on the inner wall of the hood. The oil collection tank structure is used to collect the oil.

[0030] 3. During operation, the angle of the arc-shaped stir-fry rack is adjusted as follows: First, loosen the nut and then slide the adjustment slide to raise and lower the rack. During the raising process, the arc-shaped stir-fry rack flips inward; during the lowering process, it spreads outward. This method increases the stirring surface when the arc-shaped stir-fry rack spreads outward, suitable for stir-frying small quantities of materials that are not heat-resistant and easily gelatinized, such as various spices. This method increases the stir-frying area and the stirring amplitude. When the arc-shaped stir-fry rack flips inward, its height increases, the stirring depth increases, and the stirring surface decreases. This is suitable for stir-frying large quantities of materials, such as thick sauces. If the stirring depth is insufficient, the lower layer of sauce can be stirred, but the upper layer cannot be fully stirred. Attached Figure Description

[0042] Example 1

[0043] like Figure 1-6As shown, a stir-frying device includes a stir-frying machine body 1. The stir-frying machine body 1 is a conventional stir-frying machine disclosed in the prior art, and has the same structure as existing stir-frying machines. The stir-frying machine body 1 includes a stir-frying machine 11 and a stir-frying pot 12 installed on the stir-frying machine 11. During operation, the material is stir-fried in the stir-frying pot 12.

[0044] Similar to the existing roasting machine 11, a discharge structure is installed on the roasting machine 11, including a discharge bin 13 (a valve plate is installed on the discharge bin for discharging materials after roasting is completed; the valve plate is not shown in the figure), which is used to discharge the roasted materials.

[0045] Those skilled in the art can understand the specific structure and working principle of the stir-frying machine 11 body 1 disclosed in this utility model by consulting technical manuals and dictionaries.

[0046] In order to enhance the absorption and exhaust of oil fumes during the frying process, especially during high-temperature frying, the above-mentioned device includes an oil fume extraction mechanism 3 that cooperates with the main body 1 of the frying machine 11.

[0047] Specifically, the smoke extraction mechanism 3 includes an adjustable exhaust hood 31. During normal cooking, the exhaust hood 31 covers the wok 12 with a small gap between it and the wok 12. It not only extracts smoke but also acts as a cover (to prevent dust from entering).

[0048] However, lowering the distance between the exhaust hood 31 and the wok 12 makes it difficult to add ingredients during the process due to the obstruction of the exhaust hood 31. Therefore, this utility model designs the exhaust hood 31 to be rotatable. Once ingredients are added, the exhaust hood 31 is rotated. After rotation, the distance between one side of the exhaust hood 31 and the wok 12 increases, making it easier to add ingredients.

[0049] Specifically, the top of the exhaust hood 31 is connected to a spring tube 33 (the spring tube 33 is a spring tube disclosed in the prior art, externally formed with a spring, capable of extension, retraction, and bending, possessing a high degree of freedom). In the existing method, the spring tube 33 is connected to an external exhaust duct 34 (same as the existing method, a fan is installed at the outlet of the external exhaust duct, such as an axial flow fan – not shown in the figure). During operation, the external exhaust duct 34 (only a portion of the length of the external exhaust duct 34 is shown in the figure) exhausts the fumes.

[0050] Meanwhile, the exhaust hood 31 adjusts its angle via an angle adjustment structure. This structure includes brackets 35 fixedly installed on both sides of the top of the stir-fry machine 11. The exhaust hood 31 is rotatably connected between the brackets 35 (specifically, one side of the exhaust hood 31 is rotatably connected to the bracket via a rotating shaft). A motor 32, which drives the exhaust hood 31 to rotate and adjust its angle, is mounted on the rear bracket. Specifically, the output shaft of the motor 32 is fixedly installed on the exhaust hood 31.

[0051] During operation, driven by motor 32, exhaust hood 31 flips, increasing the distance between one side of exhaust hood 31 and wok 12 for easier addition of ingredients.

[0052] In actual operation, the specific model of motor 32 is determined by the weight and volume of the exhaust hood 31, and motors with different torque are used. For example, for large-scale frying equipment, the corresponding exhaust hood is large in volume and heavy in weight, so a motor with greater torque is used. Motor 32 is a motor disclosed in the prior art, and its driving method and working principle are conventional methods disclosed in the prior art, such as the motor driving the exhaust hood to rotate 30 degrees and then stopping.

[0053] An oil collection tank structure 4 is installed inside the exhaust hood 31, and the sludge oil adhering to the inner wall of the exhaust hood 31 is collected through the oil collection tank structure 4.

[0054] Specifically, the oil collection tank structure 4 enables the collection of oil sludge on the inner wall of the exhaust hood 31 after prolonged use during operation.

[0055] Specifically, the oil collection tank structure includes an oil collection tank 41 (the oil collection tank 41 is annular in shape) that can be detachably installed inside the exhaust hood 31, and an oil collection cavity is provided inside the oil collection tank 41. The detachable method is as follows: according to the existing method, a matching threaded structure is opened on the inner side wall of the exhaust hood 31 and the outer side wall of the oil collection tank 41, and the oil collection tank 41 is installed by means of threaded connection.

[0056] An annular oil inlet 411, connecting to the oil collection chamber A, is provided on one side of the oil collection chamber 41 that abuts against the inner wall of the exhaust hood 31. During operation, oil droplets adhering to the inner wall of the exhaust hood 31 slide down the inner wall and enter the oil collection chamber A through the annular oil inlet 411 for collection. This method prevents oil from entering the wok 12 during the frying process.

[0057] The bottom of the aforementioned oil collection tank 41 is equipped with several oil discharge structures. These structures allow for the periodic discharge of oil sludge.

[0058] Specifically, the oil draining structure includes an oil draining threaded hole 412 opened on the oil collection tank 41, and a sealing bolt 421 is threadedly connected to the oil draining threaded hole 412. Unscrewing the sealing bolt 421 allows the waste oil to be drained.

[0059] Example 2

[0060] like Figure 1-6 As shown, based on the structure of Embodiment 1, the above-mentioned stir-frying device further includes a stir-frying rack mechanism 2, which includes a stir-frying rack structure disposed inside the stir-frying pot 12.

[0061] Specifically, it also includes a motor bracket 21 (spanning across the wok 12) installed at the top of the stir-frying machine 11, on which a stir-frying motor 22 is mounted. The stir-frying motor 22 is a conventional stir-frying motor disclosed in the prior art for the stir-frying machine 11.

[0062] The output end of the above-mentioned stir-frying motor 22 is fixedly installed with a stir-frying rack structure, which is used to stir-fry the materials in the wok 12.

[0063] During the frying process, in order to adjust the frying according to the amount of material added to the frying pan 12, if too much material is added to the frying pan 12, the arc-shaped frying rack is flipped upwards to increase the height of the top surface of the entire frying rack structure (hereinafter referred to as the arc-shaped frying rack) to ensure that the material is fully fryed. Conversely, if the amount of material is small, the frying rack structure (arc-shaped frying rack) is flipped downwards to increase the frying and stirring surface.

[0064] In actual operation, by adjusting the arc-shaped frying rack to change its frying and stirring surface, the stirring can also be adjusted according to the properties of the material. For example, for materials that are easily gelatinized at high temperatures (such as spices), by reducing the amount of material added, the arc-shaped frying rack can be flipped outward to increase the opening range of the entire frying rack structure and fully enhance the frying effect.

[0065] Specifically, the above-mentioned stir-fry rack structure includes a base 24, and several arc-shaped stir-fry racks 25 (the arc-shaped stir-fry racks 25 are made of stainless steel) are installed on the outer side wall of the base 24; a drive shaft is fixedly installed at the top center of the base 24, and the output shaft of the stir-fry motor is fixedly installed on the drive shaft 23, the same as in the existing method.

[0066] The angle of the arc-shaped wok rack 25 is adjusted by a flip adjustment structure; specifically, the flip adjustment structure includes a hinge interface opened on the outer wall of the base, and the lower end of the arc-shaped wok rack 25 is hinged to the hinge interface (the lower end of the arc-shaped wok rack 25 is hinged to the hinge interface by a pin).

[0067] The flipping adjustment structure also includes an adjustment slide 27 slidably connected to the drive shaft. A tension cable 26 is fixedly installed between the adjustment slide 27 and the top of the arc-shaped stir-fry rack 25. A pair of nuts 28 (with a threaded structure above the drive shaft) are threadedly connected to the drive shaft and positioned at the top and bottom of the adjustment slide 27. After the adjustment slide 27 is adjusted, the arc-shaped stir-fry rack 25 flips to adjust the stir-frying posture.

[0068] The top of the arc-shaped stir-fry rack 25 is hinged with a hanging ring, and the lower end of the traction cable 26 is fixedly connected to the hanging ring.

[0069] During operation, the angle of the arc-shaped stir-fry rack 25 is adjusted as follows: First, loosen the nut 28, then slide the adjusting slide block 27 to raise or lower it. During the raising process, the arc-shaped stir-fry rack 25 flips inward; during the lowering process, it spreads outward. This method increases the stirring surface when the arc-shaped stir-fry rack 25 spreads outward, making it suitable for stir-frying small quantities of materials that are not heat-resistant and easily gelatinize, such as various spices.

[0070] This method allows for the frying of larger portions of dough and a greater degree of stirring.

[0071] As the arc-shaped stir-fry rack 25 flips inward, its height increases, the depth of stirring increases, and the stirring surface decreases. This is suitable for stir-frying large quantities of materials, such as frying thick sauces. If the stirring depth is insufficient, the lower layer of sauce can be stirred, but the upper layer of sauce cannot be stirred sufficiently.

[0072] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
