Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in fig. 1 to 8, according to a first aspect of an embodiment of the present application, there is provided an oil filtering device 100, including: an oil filtering body 110, the oil filtering body 110 being formed with a cooking cavity 1101; a support portion 130 connected to the oil filter body 110, wherein a replacement chamber 1301 is formed between the support portion 130 and the oil filter body 110; a replacement hole 150 formed in the oil filter body 110, and the replacement chamber 1301 is connected to the cooking chamber 1101 through the replacement hole 150; the oil filtering body 110 includes a weight 112.

In the use process, the oil filter 100 provided in this embodiment may be disposed in a cooking appliance or may be used as a component of the cooking appliance, for example, the oil filter 100 may be disposed in a pan assembly 300, in this case, the support 130 of the oil filter 100 abuts against an inner bottom wall of the pan body, the displacement cavity 1301 is in communication with the cooking cavity 1101 through the displacement hole 150, a liquid for cooking food 70' and the food material 70' may be put into the displacement cavity 1101 through the displacement hole 150, and then the cooking cavity 1101 and the displacement cavity 1301 are filled with the liquid, and then the heating element 500 is further opened, so that the heating element 500 may provide heat energy for the liquid in the cooking cavity 1101 and the displacement cavity 1301, and the liquid deposition bubbles are stored in the displacement cavity 1301, so that the gas occupies at least a part of the space in the displacement cavity 1301, and the liquid deposition bubbles are pushed by the displacement cavity 1301, and then the liquid is drained from the cooking cavity 50' to the top surface of the cooking cavity 50, and the liquid is drained from the cooking cavity 50' by the suspended liquid, and the suspended grease is suspended in the top surface of the cooking cavity 50' or the cooking cavity 50' when the liquid is drained out of the top surface of the cooking cavity 50' and the liquid is preferably drained out of the top surface of the cooking cavity 110, the liquid level in the cooking chamber 1101 will decrease.

It can be appreciated that in practical applications, the air supply member may also be configured to convey the air medium into the displacement cavity 1301 by using the air supply member, so as to increase the amount and pressure of the air in the displacement cavity 1301, and further push the liquid in the displacement cavity 1301 to enter the cooking cavity 1101 through the displacement hole 150, so as to realize the filtering of the grease 50'. Also, it is understood that the oil filtering process may be performed independently of the cooking process, that is, the heating member 500 and/or the air supply member may be used to increase the amount of air in the replacement chamber 1301 after cooking the food material, so as to perform the oil filtering operation.

It should be noted that, in some examples, while the supporting end of the oil filtering device abuts against the inner bottom wall of the pan body assembly, the open end of the oil filtering device is usually formed with a gap with the inner top wall of the pan body assembly, so that only one end of the oil filtering device is restrained when in use, and when the buoyancy of the oil filtering device is changed due to the change of the pressure in the replacement cavity, the single-end restrained oil filtering device is easy to float and generate larger displacement; compared with a single-end constraint oil filter device, the oil filter body 110 of the oil filter device 100 provided by the embodiment of the application comprises the counterweight 112, and when the pressure in the replacement cavity 1301 changes in the use process, the buoyancy born by the oil filter device 100 is often caused to change, so that the weight of the oil filter body 110 can be lifted, the possibility that the oil filter device 100 floats or greatly displaces due to the buoyancy effect can be reduced, the abrasion of the oil filter device 100 is reduced, the friction and noise generated by the oil filter device 100 in the use process are reduced, the placement stability of the oil filter device 100 in the pot body assembly 300 is ensured, the possibility of pouring the soup 30' is reduced, and the guarantee is provided for the oil filter effect.

It can be appreciated that, according to the oil filtering device 100 provided by the embodiment of the application, based on the arrangement of the counterweight 112, the overall weight of the oil filtering device 100 can be increased, and then the self gravity of the oil filtering device 100 is utilized to keep stable placement, so that the arrangement of a fixed structure on the oil filtering device 100 or the pan body assembly 300 can be avoided, and the structural complexity of the oil filtering device 100 can be reduced.

It can be appreciated that one end of the oil filtering body 110 facing away from the supporting portion 130 may be formed with an opening communicating with the cooking cavity 1101, after the oil filtering device 100 and the pan body assembly 300 provided in the embodiment of the present application are combined to complete cooking of food, a user may directly take food in the cooking cavity 1101 without taking out the oil filtering device 100, so that the user may be scalded on the wall surface, and the cooking of food may be more convenient and safer.

As shown in fig. 1 to 3, in some examples, the support 130 is ring-shaped and is disposed at a circumferential side of the oil filtering body 110.

In this technical solution, the shape of the supporting portion 130 is further provided, the supporting portion 130 may be annular, and through an annular design, the supporting portion 130 may be enclosed on the periphery of the oil filtering body 110, so that the probability of generating a gap between the supporting portion 130 and the oil filtering body 110 can be reduced, the sealing effect of the replacement cavity 1301 can be improved, the gas is prevented from overflowing through the gap between the supporting portion 130 and the oil filtering body 110 when the liquid in the replacement cavity 1301 is heated to precipitate gas, the liquid in the replacement cavity 1301 is ensured to be supplied to the cooking cavity 1101 due to the precipitation of the gas, and the oil filtering effect is ensured to be achieved. Moreover, the annular supporting portion 130 can provide more reliable support for the oil filtering body 110 along the circumferential direction of the oil filtering body 110 when being abutted against the inner bottom wall of the pan body assembly 300, further improves the stability of the cooking cavity 1101, and reduces the possibility of the soup 30' being spilled.

Meanwhile, considering that the oil filter device 100 needs to be matched with the pot body assembly 300, the oil filter device 100 can be columnar, the annular design of the supporting part 130 can be better attached to the oil filter device 100, and the integrity of the oil filter device 100 is improved.

As shown in fig. 3, in some examples, oil filter apparatus 100 further includes: the liquid passing member 190 is connected to the oil filtering body 110, the liquid passing member 190 is disposed at a circumferential side of the replacement hole 150, and the liquid passing member 190 is located in the replacement chamber 1301.

In this technical solution, the oil filtering device 100 may further include a liquid filtering member 190 connected to the oil filtering body 110, where the liquid filtering member 190 is disposed at a peripheral side of the displacement hole 150 and is located in the displacement cavity 1301, so that the displacement cavity 1301 is communicated with the displacement hole 150 through the liquid filtering member 190 and then is communicated with the cooking cavity 1101, and further in a use process, when the liquid in the displacement cavity 1301 is heated to separate out bubbles or the gas is injected into the displacement cavity 1301, the liquid filtering member 190 can generate a certain blocking effect on the gas, so that the possibility that the gas directly enters the cooking cavity 1101 through the displacement hole 150 is reduced, more gas is conveniently gathered in the displacement cavity 1301, more liquid in the displacement cavity 1301 is promoted to flow to the cooking cavity 1101, which is favorable for overflowing the liquid in the cooking cavity 1101, and the oil filtering effect of the oil filtering device 100 is enhanced.

It is understood that the liquid passing member 190 may be formed with a liquid passing channel, the liquid inlet end of the liquid passing channel is connected to the displacement cavity 1301, and the liquid outlet end of the liquid passing channel is connected to the displacement hole 150, so that when the liquid passing member 190 is connected to the oil filtering body 110 and is located in the displacement cavity 1301, the liquid inlet end of the liquid passing channel is lower than the liquid outlet end, when gas exists in the displacement cavity 1301, the gas occupies a relatively higher part of the space in the displacement cavity 1301 preferentially due to the lower density of the gas than the liquid, and the liquid under the liquid passing member is extruded to flow out of the displacement cavity 1301 preferentially through the liquid passing member 190, so that the possibility that the gas directly overflows out of the displacement cavity 1301 can be reduced to a certain extent based on the arrangement of the liquid passing member 190, and the amount of the gas accumulated in the displacement cavity 1301 is increased. Illustratively, as shown in fig. 1, one end of the liquid passing member 190 is connected to the oil filtering body 110 and disposed at the circumferential side of the displacement hole 150, and the other end is disposed toward the inner bottom wall of the pan body assembly 300 with a space formed from the inner bottom wall of the pan body assembly 300.

As shown in fig. 1 to 8, in some examples, the oil filtering body 110 includes: a housing portion 111, wherein the housing portion 111 has a tubular structure with two open ends; the counterweight 112 connected to the accommodating portion 111, the counterweight 112 covering an opening of one end of the accommodating portion 111; wherein, the replacement hole 150 is opened at the weight portion 112.

In this technical solution, the oil filtering body 110 includes a containing portion 111 and a counterweight portion 112, where the containing portion 111 may be a cylindrical structure, and the interior of the cylindrical structure is hollow and two ends of the cylindrical structure are open, so as to provide a containing space for food 70' and liquid, the counterweight portion 112 is connected with the containing portion 111 and covers the opening at one end of the containing portion 111, so that under the cooperation of the counterweight portion 112 and the containing portion 111, the oil filtering body 110 is convenient to contain the food 70' and the soup 30', and the displacement hole 150 is formed in the counterweight portion 112, so that it can be understood that the supporting portion 130 may be disposed at one side of the counterweight portion 112 away from the containing portion 111, and then encloses the aforementioned displacement cavity 1301 with the counterweight portion 112.

It will be appreciated that the density of the weight 112 is greater than the density of the receptacle 111 in order to achieve a weight effect, and in some possible examples the weight 112 may have a mass greater than the mass of the receptacle 111 in order to enhance the weight effect.

As shown in fig. 3, in some examples, the weight G of the oil filter device 100, the cross-sectional area a of the oil filter device 100, and the cross-sectional area S of the displacement bore 150 satisfy:

G≥k*(A/S) (1)

In this technical solution, further provided is a constraint condition of the weight G of the oil filter device 100, the cross-sectional area a of the oil filter device 100 and the cross-sectional area S of the replacement hole 150, as shown in fig. 5 to 7, during the use of the oil filter device 100, the oil filter device 100 is often affected by the buoyancy of the liquid, so as to ensure the placement stability of the oil filter device 100 in the pan assembly 300 or other cooking equipment, for example, if the buoyancy of the oil filter device 100 is F _{Floating device} Then there is a relationship of the following inequality (2):

G≥F _{floating device} (2)

As can be seen from inequality (2), when the gravity G of the oil filter 100 is greater than or equal to the buoyancy F to which the oil filter 100 is subjected _{Floating device} As will be understood from fig. 5 to 7, the oil filter device 100 may be stably placed, and the buoyancy force-bearing surface of the oil filter device 100, which is mainly the surface of the weight 112 facing the inner bottom wall of the pan body assembly 300, is very close to the cross-sectional area a of the oil filter device 100, so that there may be the following inequality (3):

G≥pA (3)

in inequality (3), p is the pressure in the substitution chamber 1301.

It will be appreciated that, as shown in fig. 6, in the oil filtering process, the pressure p in the displacement chamber 1301 may be regarded as the air pressure in the displacement chamber 1301, and the liquid in the displacement chamber 1301 flows to the cooking chamber 1101 through the displacement hole 150 under the action of the air pressure, so that the pressure p in the displacement chamber 1301 may also be regarded as the dynamic pressure of the liquid in the displacement chamber 1301; based on the dynamic pressure formula of the fluid, the dynamic pressure of the liquid in the displacement chamber 1301 is related to the flow velocity v of the liquid passing through the displacement hole 150, and it is understood that the flow velocity v is affected by the cross-sectional area S of the displacement hole 150, and the following inequality (4) can be obtained by combining the flow formula of the fluid:

G≥f(Q)*A/S (4)

in inequality (4), Q is the flow of liquid through the displacement orifice 150 and f (Q) is a function of Q.

Taking the case of filtering oil by heating the heating material 500 as an example, Q is a constant when the power of the heating material 500 is set, that is, the flow rate of the liquid passing through the replacement hole 150 is also constant, and f (Q) can be regarded as a proportionality coefficient k related to the flow rate Q, when the heating power of the heating material 500 is in a range of 600W or more and 2200W or less, k is 0.07 or more and 0.15 or less, and the relationship of the inequality (1) can be obtained by the test.

Therefore, based on the constraint conditions of the weight G of the oil filter 100, the sectional area a of the oil filter 100, and the sectional area S of the replacement hole 150, the sectional area S of the replacement cavity 1301, and the gravity G of the oil filter 100, the oil filter 100 can overcome the buoyancy effect, and the placement stability of the oil filter 100 can be improved.

In some possible examples, the scaling factor k may be 0.09.

In some examples, the mass of oil filter device 100 is greater than or equal to 1.1kg and less than or equal to 1.8kg; and/or the diameter of the displacement bore 150 is less than or equal to 80mm; and/or the diameter of the displacement lumen 1301 is greater than or equal to 140mm and less than or equal to 200mm; the cross-sectional area of the replacement cavity is greater than or equal to 150cm ² And less than or equal to 320cm ² The method comprises the steps of carrying out a first treatment on the surface of the And/or the number of the replacement holes 150 is plural, and the sum of the sectional areas of the plurality of replacement holes 150 is 180mm or more ² And less than or equal to 5100mm ² 。

In this technical scheme, can set up the quality of oil filter 100 and be greater than or equal to 1.1kg and be less than or equal to 1.8kg to avoid oil filter 100's weight to be too little, guarantee oil filter 100's stability of placing, and can avoid oil filter 100's weight to be too big, guarantee the user convenience when getting and putting oil filter 100.

In this technical solution, the diameter of the displacement hole 150 may be set to be less than or equal to 80mm, so as to avoid that the diameter of the displacement hole 150 is too large, which makes it difficult for the displacement cavity 1301 to accumulate gas, and affects the oil filtering effect.

It should be noted that, the replacement hole 150 may be a circular hole or a non-circular hole, and it is understood that the non-circular hole may be, but is not limited to, a polygonal hole or an elliptical hole. In the case that the replacement hole 150 is a polygonal hole, the diameter of the aforementioned replacement hole 150 refers to the diameter of a polygonal circumscribing circle, it is understood that the polygonal hole may include, but is not limited to, a triangular hole, a quadrangular hole, a pentagonal hole, etc.; in the case where the replacement hole 150 is an elliptical hole, the diameter of the replacement hole 150 refers to the length of the major axis of the ellipse.

In some possible examples, the cross-sectional area of the replacement hole 150 may be used as a limitation, and the opening size of the replacement hole 150 may be defined, for example, the cross-sectional area of the replacement hole 150 may be defined to be less than or equal to 5100mm ² To avoid the excessive diameter of the filter displacement holes 150, which makes the displacement chamber 1301 difficult to accumulate gas and affects the oil filtering effect.

In this technical scheme, can set up the diameter of replacement chamber 1301 and be greater than or equal to 140mm and be less than or equal to 200mm to avoid the diameter of replacement chamber 1301 to be too little, guarantee that replacement chamber 1301 has higher volume in order to promote oil drainage efficiency, and can avoid the diameter of replacement chamber 1301 to be too big, prevent that oil filter 100 receives the buoyancy too big, guarantee oil filter 100's stability in placement.

It should be noted that, the cross section of the substitution cavity 1301 may be circular or non-circular, and it is understood that in the case that the cross section of the substitution cavity 1301 is non-circular, the cross section of the substitution cavity 1301 may be, but is not limited to, polygonal or elliptical, etc. In the case that the cross section of the substitution chamber 1301 is a polygon, the diameter of the substitution chamber 1301 refers to the diameter of the circumscribing circle of the polygon, and it is understood that the polygon may include, but is not limited to, a triangle, a quadrilateral, a pentagon, etc.; in the case where the cross section of the substitution chamber 1301 is elliptical, the diameter of the substitution chamber 1301 refers to the length of the major axis of the ellipse.

In this embodiment, the cross-sectional area of the substitution chamber 1301 may be set to be 150cm or more ² And less than or equal to 320cm ² Thereby regard the sectional area of displacement chamber 1301 as constraint condition, limit the seting up size of displacement chamber 1301, avoid the undersize of displacement chamber 1301, guarantee that displacement chamber 1301 has higher volume in order to promote oil drainage efficiency to can avoid the oversized size of displacement chamber 1301, prevent that oil filter 100 receives buoyancy too big, guarantee oil filter 100's stability of placing.
