Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0030] The fume treatment device and cooking machine of the present invention are described with reference to FIG1-7.
[0031] In one embodiment, as shown in Figures 1-7, the cooking machine's fume treatment device includes a fume exhaust assembly 100, a fan 200, and a fume purification device 300.
[0032] The smoke extraction assembly 100 includes a bracket 101 and a cantilever 102 mounted on the cooking machine. The cantilever 102 is rotatably mounted on the bracket 101 and is positioned above the cookware 400 of the cooking machine. A lid 103 is provided at the front end of the cantilever 102, which is used to cover the cookware 400. A smoke vent 1031 is provided on the lid 103. A smoke exhaust port 1021 corresponding to the position of the smoke exhaust port 1031 is provided on the bottom surface of the cantilever 102.
[0033] The exhaust port 1021 is connected to the fan 200, and the exhaust port of the fan 200 is connected to the fume purification device 300.
[0034] The shapes of the exhaust port 1021 and the smoke outlet 1031 are not limited; preferably, the exhaust port 1021 is an elongated opening, such as a rectangular or elliptical opening, and the smoke outlet 1031 is an elongated hole, such as a rectangular or elliptical hole, which can make the smoke outlet area larger, thereby improving the smoke exhaust efficiency; the oil fume purification device 300 can use existing oil fume purification equipment, and the oil fume purification device 300 is provided with an exhaust port, which can be located indoors or outdoors; the oil fume purification device 300 is preferably an oil fume purification equipment with a high purification rate, such as a purification rate higher than 95%, in which case the exhaust port can be located indoors; if the oil fume purification equipment used by the oil fume purification device 300 has a low purification rate, the exhaust port is located outdoors to avoid affecting the indoor air quality. In this case, the purified oil fume is discharged, and the oil fume concentration has been greatly reduced, which can reduce the impact on the outdoor air environment.
[0035] Specifically, the exhaust port 1021 can be directly connected to the fan 200 through a pipe, or it can be connected to the fan 200 through the cantilever 102 and the inside of the bracket 101, and then through a pipe. The exhaust port of the fan 200 is connected to the fume purification device 300 through a pipe.
[0036] Optionally, the aforementioned pipes are located inside the cooking machine body and are not exposed, making the cooking machine look simpler and easier to clean; although the pipes are not shown in the figure, they should be known to those skilled in the art.
[0037] In specific implementation, as shown in Figures 1-2, the operating surface of the cooking machine can be equipped with two sets of pots 400. Both sets of pots 400 can be used simultaneously for stir-frying, which improves the cooking efficiency compared to a single set of pots 400. The fume treatment device also includes two sets of exhaust components 100, each corresponding to one set of pots 400. When the pots 400 generate fumes during stir-frying, the lid 103 of the exhaust component 100 covers and seals the pots 400, leaving only the exhaust port 1 open. At position 021, the smoke outlet 1031 is used to draw the oil fumes from the cookware 400 into the exhaust port 1021 under the action of the fan 200. The fumes then flow along the channels inside the cantilever 102 and the bracket 101, as well as the pipes inside the cooking machine, to the fan 200. The fan 200 then transports the fumes to the oil fume purification device 300. After purification, the oil fume concentration is greatly reduced and can be directly discharged through the exhaust port, eliminating the need to place the cooking machine under the fume extraction equipment.
[0038] Optionally, the cooking machine may also be equipped with three, four, or even more sets of cookware 400, and the fume treatment device shall correspondingly have three, four, or more sets of fume extraction components 100.
[0039] The cooking machine fume treatment device provided in the above embodiment integrates the fume purification function into the cooking machine by setting up a fume exhaust component 100, a fan 200 and a fume purification device 300. The fume generated during cooking is purified and discharged directly without needing to be placed under a fume extraction device, thereby expanding the applicable environment of the cooking machine.
[0040] In this embodiment, the cantilever 102 is provided with a smoke exhaust chamber 1022 that communicates with the smoke exhaust port 1021. The smoke exhaust chamber 1022 communicates with the inner cavity of the support 101. The inner cavity of the support 101 is connected to the fan 200 through a pipe.
[0041] The rear end of the cantilever 102 is rotatably connected to the upper end of the bracket 101, and the smoke exhaust chamber 1022 is located at the rear end of the cantilever 102 and communicates with the inner cavity of the bracket 101.
[0042] Optionally, the pipe connecting the bracket 101 and the fan 200 is located inside the cooking machine body and is not exposed, making the cooking machine look simpler and easier to clean.
[0043] In practice, the fumes generated during cooking enter the exhaust chamber 1022 inside the cantilever 102 through the exhaust port 1021, and then are sucked away by the fan 200 through the pipe through the inner cavity of the bracket 101. The initial path of fume extraction is within the cantilever 102 and the bracket 101, which helps to reduce the pipe length and simplify the structure of the cooking machine.
[0044] In this embodiment, the front end of the cantilever 102 is also provided with a rotatable stirring head 104, which is located below the pot lid 103.
[0045] The cantilever 102 is also equipped with a stirring motor 105 for driving the stirring head 104 to rotate. The stirring motor 105 is located in the mounting cavity 1023 inside the cantilever 102. The mounting cavity 1023 is isolated from the exhaust cavity 1022 to prevent oil fumes from contacting the stirring motor 105 and to better protect the stirring motor 105.
[0046] In the above embodiments, in addition to the exhaust port 1021, the cantilever 102 is also equipped with a stirring head 104 and a stirring motor 105 and other stirring components. That is, the exhaust component 100 has both food stirring and exhaust functions, that is, the exhaust function is integrated into the existing stirring component, and there is no need to set up an exhaust device separately, which can simplify the structure of the cooking machine and save manufacturing costs.
[0047] In this embodiment, a vertical plate is installed at the front end of the stirring motor 105, and a horizontal plate is fixedly connected to the lower end of the vertical plate. The pot lid 103 is fixedly connected to the bottom surface of the horizontal plate.
[0048] Both the vertical plate and the horizontal plate are provided with through holes. The output shaft of the stirring motor 105 is connected to one end of the transmission mechanism 106 through the through hole on the vertical plate, and the rotating shaft of the stirring head 104 is connected to the other end of the transmission mechanism 106 through the through hole on the horizontal plate.
[0049] The stirring motor 105 is connected to the stirring head 104 via the transmission mechanism 106. In specific implementation, when the lid 103 is closed on the cookware 400, the stirring motor 105 starts working under the control of the controller of the cooking machine, driving the stirring head 104 to rotate, so as to achieve the purpose of stirring the ingredients in the cookware 400.
[0050] In this embodiment, a rotary motor 1011 is provided in the inner cavity of the bracket 101. The output shaft of the rotary motor 1011 is connected to the rear end of the cantilever 102. The cantilever 102 can rotate up and down under the drive of the rotary motor 1011.
[0051] The rotary motor 1011 is used to drive the cantilever 102 to rotate. The inner cavity of the bracket 101 serves to both install the rotary motor 1011 and allow oil fumes to pass through. Optionally, the rotary motor 1011 may be provided with a protective shell to isolate it from the oil fumes.
[0052] Specifically, when cooking, the rotary motor 1011 drives the cantilever 102 to rotate downwards, so that the stirring head 104 is located inside the pot 400 to stir the ingredients. When the cooking is finished, the rotary motor 1011 drives the cantilever 102 to rotate upwards, so that the stirring head 104 is removed from the pot 400, making it convenient for the user to take out the cooked food.
[0053] In this embodiment, the fume treatment device includes at least two fume exhaust components 100, and the number of fume exhaust components 100 is the same as the number of cookware 400.
[0054] The cooking machine can have 2 to 4 sets of cookware 400, and the fume treatment device includes 2 to 4 sets of exhaust components 100. In practice, by having at least two exhaust components 100 work together with the same number of cookware 400, they can be used simultaneously for stir-frying, making the cooking machine more efficient.
[0055] In this embodiment, the exhaust port 1021 is a rectangular opening and the smoke outlet 1031 is an elliptical hole, which increases the area through which oil fumes can pass, thereby improving the smoke exhaust efficiency.
[0056] In another embodiment, as shown in FIG7, the present invention provides a cooking machine, which includes an upper head 500, a lower body 600, and an oil fume treatment device as described in any of the above embodiments. The body 600 is provided with at least two pots 400, the smoke exhaust component 100 is provided on the body 600, and the fan 200 and the oil fume purification device 300 are provided inside the head 500.
[0057] The cooking machine provided in this embodiment uses the above-mentioned fume treatment device, which eliminates the need to place it under the fume extraction equipment, thereby improving the working environment of the cooking machine.
[0058] In this embodiment, the operating table 601 of the body 600 is an inclined surface that is lower in the front and higher in the back.
[0059] In practical implementation, cooking machines need to use a countertop that is lower in the front and higher in the back for easy operation. However, the countertops of existing products on the market are generally stepped, which is inconvenient to clean. The operating countertop 601 in the above embodiment is a sloping surface that is lower in the front and higher in the back, which is easy to clean.
[0060] In this embodiment, the fume purification device 300 is located at the front of the head unit 500, and the fan 200 is located at the rear of the head unit 500. Several heat dissipation holes 501 are provided on the rear housing of the head unit 500 to prevent overheating.
[0061] The oil fume treatment device of the cooking machine according to the embodiments of the present invention, as well as other components and operation of the cooking machine, are known to those skilled in the art and will not be described in detail here.
