[0037] As Figure 1 and Figure 7 As shown, the cookware provided by the present invention includes: a pot body 3 and a gas source. An air duct 1 is arranged on the pot body 3 along its circumferential direction. The air duct 1 and the pot body 3 can be connected together by welding. The air duct 1 surrounds the pot body 3 in a circle. The air duct 1 has an annular air outlet 110 with an opening facing upward; an air inlet is arranged on the air duct 1. The gas source is connected to the pot body 3, and the air outlet end of the gas source is connected to the air inlet. The gas source is used to input gas into the air duct 1. The gas generated by the gas source enters the air duct 1 through the air inlet, flows in a circular shape in the air duct 1 to various positions of the air duct 1, and finally flows out from the annular air outlet 110.
[0038] The gas generated by the gas source can be ejected upward from the annular air outlet 110 around the pot body 3, so as to form a negative pressure area in the area near the pot body 3. The negative pressure area is mainly concentrated in a small area around the air duct 1, and causes the air outside the pot body 3 to flow and gather towards the center of the pot body 3. Since the air outlet 110 faces upward, the gathered gas is driven to flow upward at the same time, preventing the smoke from diffusing around.
[0039] As Figure 3As shown, the air source includes a housing 4. An inlet, an outlet, and a diversion channel connecting the inlet and the outlet are provided on the housing 4. The outlet forms the air outlet end and is connected to [the relevant part]. A fan 5 is provided in the diversion channel, and the fan 5 is used to generate an air flow flowing from the inlet to the outlet. In this embodiment, the housing 4 is in a straight tube shape. When the housing 4 can be fixed to the pot body 3 through [the relevant part] and form a handle for controlling the cooking utensil.
[0040] As Figure 3 and Figure 5 shown, the distal end of the branch-shaped housing 4 can be threadedly connected to the threaded interface 8 on [the relevant part] to achieve air conduction. The inlet of the housing 4 is provided with an air inlet cover 7 with a grille, which can prevent sundries from entering the housing 4 together with the air and blocking the channel.
[0041] As Figure 2 and Figure 6 shown, an openable and closable battery compartment 6 is provided on the outer wall of the housing 4. The battery compartment 6 includes a compartment body and a compartment cover. The compartment body can be integrally formed with the housing 4, and the compartment cover is detachably connected to the compartment body, for example, by using a buckle or a screw connection. The battery compartment 6 is used to accommodate a battery, and the battery compartment 6 is electrically connected to the fan 5, and the battery is used to supply power to the fan 5.
[0042] As Figure 4 shown, the air duct 1 internally has a variable-diameter channel 9. The outlet of the variable-diameter channel 9 forms the air outlet 110, and the air flow in the air duct 1 flows out through the variable-diameter channel 9; and from inside to outside, the cross-section of the variable-diameter channel 9 gradually decreases.
[0043] The air flow that enters the air duct 1 and flows in a circular shape along the air duct 1 will enter the circular variable-diameter channel 9. Since the cross-sectional area of the variable-diameter channel 9 gradually decreases, the air pressure of the air flow will also change. Specifically, according to Bernoulli's principle, due to the decrease in cross-sectional area, the flow rate of the outflowing gas increases, for example, about 15 times (theoretical calculated value); according to the Coanda effect, the high-speed air flow flows upward. Due to the high flow rate and low air pressure, a negative pressure area is formed in the area near the air outlet 110.
[0044] Specifically, the air duct 1 includes an annular bottom wall 10, and an annular inner wall 11 and an annular outer wall 12 arranged in the radial direction. The annular inner wall 11 is connected to the outer wall of the pot body 3, and the annular outer wall 12 is located outside the annular inner wall 11; the radially inner edge of the annular bottom wall 10 is connected to the lower edge of the annular inner wall 11, and the radially outer edge of the annular bottom wall 10 has an upwardly turned first flange 13, and the first flange 13 is located radially outside the annular outer wall 12.
[0045] The annular bottom wall 10, and the annular inner wall 11 and the annular outer wall 12 arranged in the radial direction approximately enclose an annular channel that is narrower at the top and wider at the bottom. Among them, from top to bottom, the annular inner wall 11 inclines towards the radial inner side, and a plurality of connecting ribs 2 can be arranged between its outer side wall and the outer side wall of the pot body 3 to improve the connection stability between the air passage 1 and the pot body 3. The first flanging 13 warps upwards, and the first flanging 13 and the annular bottom wall 10 are in arc transition to reduce the air flow resistance. From bottom to top, the first flanging 13 can be slightly inclined outwards, so that the first flanging 13 and the radial outer side wall of the annular outer wall 12 form a part of the variable-diameter channel 9, that is, at the channel formed by the first flanging 13 and the radial outer side wall of the annular outer wall 12, from inside to outside, its cross-section gradually decreases.
[0046] The lower edge of the annular inner wall 11 has a second flanging 14 that is turned upwards, and the second flanging 14 and the annular inner wall 11 are in arc transition, with less resistance to the air flow. The turning direction of the second flanging 14 is opposite to that of the first flanging 13, and the second flanging 14 and the annular bottom wall 10 form a part of the variable-diameter channel 9. In this embodiment, the channel formed by the second flanging 14 and the annular bottom wall 10, and the channel formed by the first flanging 13 and the annular outer wall 12 together constitute the variable-diameter channel 9.
[0047] The value range of the difference between the inner diameter and the outer diameter of the annular air outlet 110 is 0.8 mm - 1.2 mm, for example, it is 1 mm.
[0048] In other implementable solutions, the housing 4 may not form a handle, and the cookware has a separate handle.
[0049] It should be specifically noted that a proximity switch can be arranged on the top surface of the housing 4, and the proximity switch is triggered by whether the laser is blocked. After the pot lid is buckled on the pot body 3, a part of the pot lid can block the proximity switch, and the fan 5 connected to the proximity switch automatically closes. Thereby, the power consumption can be saved, because when the pot lid is buckled, the amount of oil fume is low, and only relying on the range hood can complete the oil fume suction. Only when the pot body 3 is open, the oil fume is more likely to escape.
[0050] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
