Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A bubble breaking device 10 for a cooking appliance according to an embodiment of the first aspect of the present invention is described below with reference to the accompanying drawings. For example, the cooking appliance is an electric pressure cooker.
As shown in fig. 1 to 7, according to the bubble breaking device 10 for the cooking appliance of the embodiment of the present invention, the lid of the cooking appliance has the air discharge passage 20, and the bubble breaking device 10 includes a body adapted to be connected to the lid.
Specifically, the body is provided with an air passing cavity 221 and a bubble breaking flow channel 222, the air passing cavity 221 is suitable for being communicated with the exhaust channel 20, and the bubble breaking flow channel 222 is externally wound around the air passing cavity 221 and is configured into an open ring shape or a closed ring shape. The body is provided with a foam inlet hole 211 and a gas inlet 224, the foam inlet hole 211 is communicated with the foam breaking flow channel 222 and a cooking cavity of the cooking appliance, and the gas inlet 224 is communicated with the foam breaking flow channel 222 and the gas passing cavity 221.
Wherein, the gas-liquid mixture (i.e. bubbles) in the cooking cavity is suitable for entering the bubble breaking flow channel 222 from the gas inlet hole 211, and the gas-liquid mixture flows along the circumferential direction of the bubble breaking flow channel 222 to break bubbles and realize gas-liquid separation under the action of centrifugal force, and the gas formed by gas-liquid separation is suitable for entering the gas passing cavity 221 from the gas inlet 224.
Thus, during the exhaust and pressure reduction of the cooking fluid food, a large amount of bubbles are generated in the cooking cavity, and the bubbles are continuously accumulated and enter the body from the inlet holes 211 respectively. Next, the bubbles entering from the bubble inlet hole 211 flow at a high speed under the guidance of the bubble breaking flow path 222: because the bubble is composed of the gas inside and the liquid wrapped outside the gas, and the gas and the liquid have different densities, when the liquid and the gas flow together in a mixed mode, the centrifugal force applied to the liquid is larger than that applied to the gas, and therefore the bubble can be broken and gas-liquid separation can occur. The separated liquid will adhere to the body and collect together under the action of gravity, and the separated gas will exit the bubble breaking device 10 through the air exit passage 20, from where the liquid exits to the cooking chamber.
According to the bubble breaking device 10 for the cooking utensil provided by the embodiment of the invention, bubbles are broken and gas-liquid separated by centrifugal motion, so that gas-liquid separated liquid flows back to the cooking cavity and gas is discharged from the cooking cavity, and high gas-liquid separation efficiency, good bubble breaking and anti-overflow effects and exhaust and depressurization effects are realized with a simple structure and low cost. Therefore, food overflow and kitchen pollution are avoided, the body can be detached for cleaning, and liquid residue is avoided to pollute food. In addition, the user can not be scalded, and the device is safe and reliable.

The bubble-breaking sealing member 220 extends into the housing cavity, the bubble-breaking sealing member 220 divides the housing cavity into a bubble-breaking flow passage 222 and a gas passing cavity 221, and the gas inlet 224 is arranged on the peripheral wall of the bubble-breaking sealing member 220. Wherein, the bubble-breaking sealing member 220 is detachably engaged with the air outlet 101 and the exhaust passage 20, respectively, and seals the gap between the mounting seat 100 and the exhaust passage 20.
In the process of exhausting and depressurizing the cooking fluid food, the bubble breaking flow channel 222 guides the bubbles entering from the bubble inlet hole 211 to flow at a high speed, the bubbles can be broken, gas and liquid separation can be carried out, the separated liquid can be attached to the side walls of the bubble breaking cover body 210 and the bubble breaking sealing piece 220 and can be converged together under the action of gravity, and the separated gas is discharged out of the bubble breaking device 10 through the exhaust channel 20.

For example, the bead 226 extends circumferentially of the bubble-breaching seal 220, and the bead 226 is located below the air inlet 224.
In some embodiments of the present invention, as shown in fig. 7, the bubble-breaking seal 220 has a rib 228 on the lower outer periphery thereof, and the rib 228 protrudes outward and extends to a position right above the at least one drainage hole 212, so that bubbles entering the bubble-breaking cover 210 from the drainage hole 212 can be broken by the rib 228 during air exhaust.
