[0063] Exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.
[0064] As Figures 1 to 11 shown, according to the embodiment of the present disclosure, a pressure cooking utensil is provided, comprising: a pot body assembly 100; a pot cover assembly 200 arranged on the pot body assembly 100, and a cooking cavity 101 is formed between the pot body assembly 100 and the pot cover assembly 200; an exhaust assembly 300 arranged on the pot cover assembly 200; and a anti-blocking assembly 400 formed with a filter hole 401, and an air inlet 301 of the exhaust assembly 300 is communicated with the cooking cavity 101 through the filter hole 401; wherein the minimum distance between the filter hole 401 and the bottom of the pot body assembly 100 is greater than or equal to the distance between the air inlet 301 and the bottom of the pot body assembly 100.
[0065] The pressure cooking utensil provided by the embodiment of the present disclosure comprises a pot body assembly 100, a pot cover assembly 200, an exhaust assembly 300 and an anti-blocking assembly 400, wherein the pot body assembly 100 and the pot cover assembly 200 form a cooking cavity 101, which can be used to accommodate food materials to be cooked; the exhaust assembly 300 is arranged on the pot cover assembly 200 and can be used to communicate the cooking cavity 101 with the external environment, so that the cooking cavity 101 can be exhausted and depressurized; the anti-blocking assembly 400 is formed with a filter hole 401, and the air inlet 301 of the exhaust assembly 300 can be communicated with the cooking cavity 101 through the filter hole 401, so that when the exhaust assembly 300 is communicated, the gas in the cooking cavity 101 can flow to the air inlet 301 of the exhaust assembly 300 through the filter hole 401 and can contact the anti-blocking assembly 400 when flowing through the filter hole 401, accordingly, the gas bubbles carried by the gas are also easy to contact the anti-blocking assembly 400 when flowing through the filter hole 401, thereby increasing the probability of bubble rupture; and by setting the minimum distance between the filter hole 401 and the bottom of the pot body assembly 100 to be greater than or equal to the distance between the air inlet 301 and the bottom of the pot body assembly 100, the filter hole 401 can be arranged at a relatively high position, thereby in the process of exhaust and depressurization, on the one hand, the difficulty of bubbles rising to the filter hole 401 along with the gas flow can be increased, which is beneficial to reducing the amount of bubbles at the filter hole 401, on the other hand, the flow path of the gas in the cooking cavity 101 flowing to the air inlet 301 can be prolonged, which improves the rupture probability of bubbles in the flow process; based on this, the pressure cooking utensil provided by the embodiment of the present disclosure can reduce the possibility of bubbles gathering or entering the air inlet of the exhaust assembly 300, ensure the exhaust effect of the exhaust assembly 300 and reduce the risk of liquid produced after bubble rupture overflowing through the exhaust assembly 300, reduce the cleaning burden of the pressure cooking utensil, and is beneficial to prolonging the continuous exhaust time of the pressure cooking utensil, shortening the time consumption of the pressure cooking utensil, facilitating the pressure condition of quickly reaching the opening cover after cooking, and improving the user experience of the product.
[0066] It should be noted that the pressure cooker in the prior art is prone to liquid overflow during exhaust and pressure relief, so the continuous exhaust time of the exhaust device is usually shortened, and the exhaust device is controlled to exhaust and relieve pressure multiple times with a short single duration to avoid the liquid level in the cooking space rising too much to cause liquid overflow, thereby reducing the pressure relief efficiency of the pressure cooker and being not conducive to the user to quickly open the cover to take food after cooking. Compared with the prior art, the pressure cooking utensil provided by the embodiments of the present disclosure can reduce the possibility of bubbles gathering in or entering the air inlet end of the exhaust assembly 300 during exhaust and pressure relief, thereby reducing the influence of the liquid level rise in the cooking cavity 101 on the exhaust process of the exhaust assembly 300 and the probability of liquid overflow of the exhaust assembly 300, and thereby facilitating to prolong the continuous exhaust time of the pressure cooking utensil, shorten the pressure relief time of the pressure cooking utensil, and facilitate the user to quickly open the cover to take food after cooking.
[0067] It can be understood that the pot body assembly 100 is formed with a pot opening, and the pot cover assembly 200 can be used to cover or open the pot opening. The bottom of the pot body assembly 100, i.e., the end of the pot body assembly 100 opposite to the pot opening; when the pot cover assembly 200 covers the pot opening, the cooking cavity 101 is formed between the pot cover assembly 200 and the pot body assembly 100; the connection form between the pot cover assembly 200 and the pot body assembly 100 can be various, such as movable connection or detachable connection, etc., which is not limited here.
[0068] It can be understood that the minimum distance between the filter hole 401 and the bottom of the pot body assembly 100 is greater than or equal to the distance between the air inlet 301 and the bottom, which is in the case that the pot cover assembly 200 covers the pot opening. In the case that the pot cover assembly 200 covers the pot opening, the conduction direction of the filter hole 401 can be perpendicular to the bottom, or can be not perpendicular to the bottom. Similarly, in the case that the pot cover assembly 200 covers the pot opening, the conduction direction of the air inlet 301 can be perpendicular to the bottom, or can be not perpendicular to the bottom. In the case that the conduction direction of the air inlet 301 is not perpendicular to the bottom, the distance between the air inlet 301 and the bottom can also be the minimum distance therebetween.
[0069] It can be understood that the aforementioned anti-blocking assembly 400 can be in a cover-like or ring-like or sleeve-like structure, and the air inlet end of the exhaust assembly 300 can be located on the inner side of the anti-blocking assembly 400, so that when the anti-blocking assembly 400 is located in the transition cavity 502, the anti-blocking assembly 400 can isolate the transition cavity 502 and the air inlet end of the cooking assembly to a certain extent, and the aforementioned filter hole 401 can conduct the inner side and the outer side of the anti-blocking assembly 400, so that the air inlet end of the exhaust assembly 300 can be communicated with the transition cavity 502 through the filter hole 401, and the breaking effect of the anti-blocking assembly 400 on the bubbles can be improved, and the possibility of bubbles gathering or entering the air inlet end of the exhaust assembly 300 can be reduced.
[0070] It can be understood that based on the position difference between the aforementioned filter hole 401 and the aforementioned air inlet 301, the flow direction of the gas in the cooking cavity 101 can change when flowing to the air inlet 301 through the filter hole 401, thereby facilitating further extending the flow path of the gas in the cooking cavity 101 when flowing to the air inlet 301, and increasing the probability of breaking bubbles during the flow process.
[0071] It can be understood that when the exhaust assembly 300 is exhausting, if the solid food in the cooking cavity 101 is close to the exhaust assembly 300 due to the influence of pressure, the anti-blocking assembly 400 can block the aforementioned solid food, prevent the solid food from entering the exhaust assembly 300, and reduce the risk of blocking the exhaust assembly 300.
[0072] As shown in Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 10 and Figure 11 , in some examples, the aforementioned anti-blocking assembly 400 includes: an anti-blocking cover 430, which is arranged on the air inlet end of the aforementioned exhaust assembly 300, and the aforementioned air inlet 301 is formed on the air inlet end and located on the inner side of the aforementioned anti-blocking cover 430; wherein the aforementioned filter hole 401 is formed in the aforementioned anti-blocking cover 430.
[0073] In the technical solution, the aforementioned anti-blocking assembly 400 can include an anti-blocking cover 430 covering the air inlet end of the aforementioned exhaust assembly 300. It can be understood that the air inlet 301 of the exhaust assembly 300 is formed at the aforementioned air inlet end, and the aforementioned filter hole 401 is formed in the aforementioned anti-blocking cover 430. The aforementioned air inlet end can be arranged between the pot body assembly 100 and the pot cover assembly 200, so that the air inlet 301 of the exhaust assembly 300 accesses the gas in the cooking cavity 101 through the filter hole 401 in the aforementioned anti-blocking cover 430. Based on the aforementioned arrangement, the anti-blocking assembly 400 can use the anti-blocking cover 430 to cover the air inlet end of the exhaust assembly 300, thereby enhancing the separation effect between the air inlet 301 and the cooking cavity 101. During the exhaust pressure relief process, more gas in the cooking cavity 101 can flow to the air inlet 301 through the filter hole 401, thereby improving the breaking effect of the anti-blocking assembly 400 on the bubbles and increasing the breaking probability of the bubbles during the flow to the air inlet 301.
[0074] It can be understood that the aforementioned air inlet end, i.e., the part where the air inlet 301 of the exhaust assembly 300 is formed, can be located between the pot body assembly 100 and the pot cover assembly 200 in some examples. Correspondingly, the aforementioned anti-blocking cover 430 is also located between the pot body assembly 100 and the pot cover assembly 200. In actual application, the anti-blocking cover 430 can be connected to the pot body assembly 100 and / or the pot cover assembly 200 to improve the setting stability of the anti-blocking cover 430.
[0075] As shown in Figure 2 , Figure 3 , Figure 7 , Figure 10 and Figure 11 , in some examples, the aforementioned anti-blocking cover 430 includes: an annular portion 431 covering the aforementioned air inlet end, the aforementioned filter hole 401 being formed in the annular portion 431, one end of the aforementioned filter hole 401 being located at the outer peripheral wall of the aforementioned annular portion 431, the other end being located at the inner peripheral wall of the aforementioned annular portion 431, and the aforementioned air inlet 301 being located at the inner side of the aforementioned annular portion 431; an end plate 432 arranged at the aforementioned annular portion 431, and the aforementioned pot cover assembly 200 and the aforementioned end plate 432 covering the two open ends of the aforementioned annular portion 431, respectively.
[0076] In the technical solution, the aforementioned anti-blocking cover 430 can include an annular portion 431 sleeved on the air inlet end of the exhaust assembly 300 and an end plate 432 arranged on the annular portion 431, the aforementioned filter hole 401 can be arranged on the annular portion 431 and pass through the inner and outer circumferential walls of the annular portion 431, and the aforementioned air inlet 301 can be located on the inner side of the annular portion 431. It can be understood that the annular portion 431 is a structure with both ends open and hollow inside. Correspondingly, one end of the annular portion 431 can be covered by the pot cover assembly 200, and the other end can be covered by the aforementioned end plate 432. Based on the aforementioned arrangement, the anti-blocking cover 430 can cooperate with the pot cover assembly 200 to separate the aforementioned air inlet 301 and the aforementioned cooking cavity 101, and can use the aforementioned filter hole 401 to connect the air inlet 301 and the cooking cavity 101, to provide a path for the gas in the cooking cavity 101 to exhaust, limit the path of the gas in the cooking cavity 101 to the aforementioned air inlet 301, and facilitate to improve the flow of the filter hole 401 during exhaust, thereby enhancing the filtering effect and bubble breaking effect of the anti-blocking cover 430, and reducing the probability of the exhaust assembly 300 being blocked or overflowing with liquid.
[0077] It can be understood that the annular portion 431 and the pot cover assembly 200 can be in a detachable connection relationship, so as to facilitate cleaning and maintenance of the anti-blocking cover 430 in actual application.
[0078] It can be understood that the shape of the aforementioned annular portion 431 can be various, for example, the aforementioned annular portion 431 can be but not limited to a circular ring structure or an elliptical ring structure or a polygonal ring structure, etc., which can be set according to actual needs, and will not be limited here.
[0079] As shown in Figure 2 , Figure 3 , Figure 7 , Figure 10 and Figure 11 , in some feasible examples, the arrangement direction of the two ends of the annular portion 431 can be consistent with the depth direction of the cooking cavity 101, so as to make the connection direction of the filter hole 401 intersect with the depth direction of the cooking cavity 101.
[0080] It can be understood that, in the process of discharging the pressure cooking appliance, high-pressure area gas flows to low-pressure area. Since the aforementioned exhaust assembly 300 is arranged on the pot cover assembly 200, the position of the air inlet 301 of the exhaust assembly 300 is relatively high, and the pressure gradient in the cooking cavity 101 during the exhaust process is greater in the depth direction. Based on the foregoing arrangement, on the one hand, the conductive direction of the filter hole 401 is different from the depth direction of the cooking cavity 101, thereby avoiding the direction with high pressure gradient, avoiding the bubbles or liquid in the cooking cavity 101 from rapidly approaching the filter hole 401 during the rising process, and facilitating the extension of the continuous exhaust time; on the other hand, it is also beneficial to further increase the position height of the filter hole 401, increase the distance between the filter hole 401 and the liquid level in the cooking cavity 101, so that the filter hole 401 is at a height position with relatively low bubble amount. Thus, compared with the example that the filter hole 401 is conductive along the depth direction of the cooking cavity 101, the technical solution can increase the distance between the filter hole 401 and the liquid level, and can make the filter hole 401 more easily access the gas with less bubble amount in the upper layer of the cooking cavity 101 during the exhaust and pressure relief process, further reducing the influence of the rising of the liquid level in the cooking cavity 101 on the exhaust and pressure relief.
[0081] In some examples, the ratio of the sum of the conductive areas of the filter holes 401 to the area of the outer peripheral wall of the annular portion 431 is greater than or equal to 0.5% and less than or equal to 4%; and / or the sum of the conductive areas of the filter holes 401 is greater than or equal to the conductive area of the air inlet 301.
[0082] In the technical solution, the ratio of the sum of the conductive areas of the filter holes 401 to the area of the outer peripheral wall of the annular portion 431 can be greater than or equal to 0.5% and less than or equal to 4%. It can be understood that the number of the filter holes 401 can be greater than or equal to 1. In the case that the number of the filter holes 401 is one, the sum of the conductive areas of the filter holes 401 is the conductive area of the filter hole 401. Based on the foregoing arrangement, the overall conductive area of the filter holes 401 can be avoided to be too large or too small, thereby on the one hand, the overall flow of the filter holes 401 during the exhaust and pressure relief process can be avoided to be too large, the rising rate of the liquid level in the cooking cavity 101 can be reduced, thereby reducing the bubble amount passing through the filter holes 401, and facilitating the reduction of the probability of liquid overflow of the exhaust assembly 300 and the extension of the continuous exhaust time of the exhaust assembly 300; on the other hand, the overall flow of the filter holes 401 during the exhaust and pressure relief process can also be avoided to be too small, thereby guaranteeing the exhaust and pressure relief efficiency of the pressure cooking appliance.
[0083] In the technical solution, the sum of the passage areas of the filter holes 401 can be greater than or equal to the passage area of the air inlet 301, thereby facilitating to ensure the flow rate of the exhaust assembly 300 during exhaust, and providing guarantee for the exhaust pressure relief efficiency of the pressure cooking appliance.
[0084] It can be understood that in actual application, the sum of the passage areas of the filter holes 401 can be greater than or equal to the passage area of the air inlet 301 while the ratio of the sum of the passage areas of the filter holes 401 to the area of the outer peripheral wall of the annular portion 431 is greater than or equal to 0.5% and less than or equal to 4%.
[0085] It can be understood that the passage area of the filter hole 401, i.e., the cross-sectional area of the filter hole 401, can vary along the passage direction or be constant in actual application. In the case where the passage area of the filter hole 401 varies along the passage direction, the passage area of the filter hole 401 can be the maximum passage area or the minimum passage area or the average passage area of the filter hole 401. Similarly, the passage area of the air inlet 301, i.e., the cross-sectional area of the air inlet 301, can vary along the passage direction or be constant in actual application. In the case where the passage area of the air inlet 301 varies along the passage direction, the passage area of the air inlet 301 can be the maximum passage area or the minimum passage area or the average passage area of the air inlet 301.
[0086] It can be understood that the cross-sectional shape of the filter hole 401 can be various, for example, the filter hole 401 can include but is not limited to a round hole, an oblong hole, a waist-shaped hole, an oval hole, a polygonal hole, etc., which can be set according to actual needs, and is not limited herein.
[0087] Exemplarily, the ratio of the sum of the passage areas of the filter holes 401 to the area of the outer peripheral wall of the annular portion 431 can be but is not limited to 0.8%, 1%, 1.5%, 2%, 2.3%, or 3.5%, etc.
[0088] In some feasible examples, the passage area of each filter hole 401 can be less than or equal to 3mm 2 and greater than or equal to 1mm 2 , for example, 1.5mm 2 , 2mm 2 , or 2.5mm 2 , etc.; the sum of the passage areas of the filter holes 401 can be less than or equal to 40mm 2 and greater than or equal to 25mm 2 , for example, 28mm 2 , 31.5mm 2 , or 31.5mm2 etc.
[0089] like Figure 2 , Figure 5 , Figure 10 and Figure 11 As shown, in some examples, a transition space 4301 is formed between the inner peripheral wall of the aforementioned annular portion 431 and the aforementioned air intake end, and the aforementioned transition space 4301 is connected between the aforementioned filter hole 401 and the aforementioned air intake 301.
[0090] In this technical solution, a transition space 4301 can be formed between the inner peripheral wall of the aforementioned annular portion 431 and the aforementioned air inlet end, which connects the aforementioned filter hole 401 and the aforementioned air inlet 301. Based on the aforementioned arrangement, the pressure cooking appliance can further utilize the aforementioned transition space 4301 to buffer the gas during the exhaust and depressurization process, and extend the flow path of the gas between the filter hole 401 and the air inlet 301. Correspondingly, if there are bubbles flowing from the filter hole 401 to the air inlet 301, the probability of the bubbles bursting before flowing into the air inlet 301 can be further increased, reducing the probability of liquid overflow from the exhaust assembly 300.
[0091] like Figures 5 to 7 As shown, in some examples, the aforementioned exhaust assembly 300 includes: an exhaust valve 310 disposed on the aforementioned pot lid assembly 200; a hanging shaft 320 disposed on the aforementioned exhaust valve 310, the aforementioned hanging shaft 320 being located between the aforementioned pot lid assembly 200 and the aforementioned pot bottom, the aforementioned air inlet 301 being formed on the aforementioned hanging shaft 320, and the input end of the aforementioned exhaust valve 310 being connected to the aforementioned air inlet 301; wherein, the aforementioned end plate 432 is provided with a mating hole 4302, and the aforementioned hanging shaft 320 is inserted through the aforementioned mating hole 4302.
[0092] In this technical solution, the aforementioned exhaust assembly 300 may include an exhaust valve 310 disposed on the lid assembly 200 and a hanging shaft 320 connected to the exhaust valve 310. The aforementioned air inlet 301 is formed on the hanging shaft 320 and connected to the input end of the exhaust valve 310. Correspondingly, the aforementioned hanging shaft 320 is located between the lid assembly 200 and the bottom of the pot. On the one hand, the pressure cooking appliance can easily use the hanging shaft 320 to install the components between the lid assembly 200 and the pot body assembly 100, thereby improving the structural compactness of the pressure cooking appliance. On the other hand, it can also facilitate the intake of gas in the cooking chamber 101 through the air inlet 301. The output end of the exhaust valve 310 can be used to connect to the external environment. The end plate 432 of the aforementioned anti-blocking cover 430 may be provided with a mating hole 4302. The aforementioned hanging shaft 320 can pass through the mating hole 4302 to facilitate the connection of the hanging shaft 320 with other components in actual applications.
[0093] In some possible examples, the hanging shaft 320 is threadedly connected with the exhaust valve 310. For example, the hanging shaft 320 can be formed with an internal thread, and the exhaust valve 310 can be formed with an external thread.
[0094] As shown in FIG. 10, in some possible examples, the hanging shaft 320 can be arranged along the depth direction of the cooking cavity 101, and the air inlet 301 can be formed in the side of the hanging shaft 320, so that the air inlet 301 is arranged to be perpendicular to the depth direction of the cooking cavity 101. Figures 5 to 7
[0095] It can be understood that, in the process of discharging the pressure cooking appliance, the gas in the high-pressure area flows to the low-pressure area. Since the exhaust assembly 300 is arranged on the pot cover assembly 200, the air inlet 301 of the exhaust assembly 300 is arranged to be relatively high, and the pressure gradient in the cooking cavity 101 is greater in the depth direction during the discharging process. Based on the above arrangement, on the one hand, the air inlet 301 is arranged to be perpendicular to the depth direction of the cooking cavity 101, so as to avoid the direction with a high pressure gradient, and to prevent the bubbles or liquid in the cooking cavity 101 from rising to the air inlet 301 rapidly, thereby prolonging the continuous discharging time. On the other hand, the height of the air inlet 301 is further increased, and the distance between the air inlet 301 and the liquid level in the cooking cavity 101 is increased, so that the air inlet 301 is arranged to be at a height position with a relatively small amount of bubbles. Thus, compared with the example in which the air inlet 301 is arranged to be perpendicular to the depth direction of the cooking cavity 101, the arrangement of the hanging shaft 320 along the depth direction of the cooking cavity 101 and the arrangement of the air inlet 301 in the side of the hanging shaft 320 can increase the distance between the air inlet 301 and the liquid level, and can make the air inlet 301 more easily access the gas with a small amount of bubbles in the upper layer of the cooking cavity 101 during the discharging process, thereby further reducing the influence of the rising of the liquid level in the cooking cavity 101 on the discharging process.
[0096] As shown in FIG. 10, in some possible examples, the hanging shaft 320 is threadedly connected with the exhaust valve 310. For example, the hanging shaft 320 can be formed with an internal thread, and the exhaust valve 310 can be formed with an external thread. Figure 5 As shown in FIG. 10, in some possible examples, the hanging shaft 320 is threadedly connected with the exhaust valve 310. For example, the hanging shaft 320 can be formed with an internal thread, and the exhaust valve 310 can be formed with an external thread.
[0097] In the technical scheme, the aforementioned anti-blocking assembly 400 can include a mounting seat 410, and the aforementioned exhaust assembly 300 can include a sealing element 330, wherein the mounting seat 410 is sleeved on the exhaust valve 310 and arranged between the lid assembly 200 and the hanging shaft 320, and the annular portion 431 of the anti-blocking cover 430 is detachably mounted on the mounting seat 410, so as to facilitate stable and reliable position keeping in actual application, facilitate cleaning and maintenance of the anti-blocking cover 430, and facilitate covering of the annular portion 431 by the lid assembly 200; the sealing element 330 is sleeved on the exhaust valve 310 and arranged between the mounting seat 410 and the lid assembly 200, so that the pressure cooking appliance can block the gap between the mounting seat 410, the lid assembly 200 and the exhaust valve 310 by the sealing element 330, reduce the probability of bubbles or solid food materials entering the gap, and facilitate further improvement of reliability and cleanliness of the pressure cooking appliance.
[0098] As shown in Figure 5 some examples, the mounting seat 410 is formed with an elastic connecting structure, the annular portion 431 is formed with a cooperating structure, and the elastic connecting structure is detachably clamped on the cooperating structure.
[0099] In the technical scheme, the annular portion 431 can be formed with a cooperating structure, and the mounting seat 410 can be formed with an elastic connecting structure suitable for being detachably clamped on the cooperating structure, based on the above arrangement, the convenience of disassembling the anti-blocking cover 430 from the mounting seat 410 can be improved, and cleaning of the anti-blocking cover 430 by the user is further facilitated, which is beneficial to further improving the user experience of the product.
[0100] It can be understood that the mounting seat 410 can be made of an elastic material, and the elastic connecting structure can be integrally formed with the mounting seat 410.
[0101] As shown in Figure 11 some examples, the side of the lid assembly 200 facing the pot bottom is formed with a receiving groove 201, the receiving groove 201 is recessed in a direction away from the pot bottom, and the filter hole 401 is located in the receiving groove 201.
[0102] In the technical solution, the lid assembly 200 can be formed with a receiving groove 201 located on the side of the lid assembly 200 facing the pot bottom and recessed away from the pot bottom. The filter hole 401 of the anti-blocking assembly 400 is located in the receiving groove 201, that is, the part of the anti-blocking assembly 400 with the filter hole 401 is located in the receiving groove 201. Based on the above arrangement, the position of the filter hole 401 can be further improved under the condition that the minimum distance between the lid assembly 200 and the pot bottom is constant. In the process of exhaust pressure relief, on the one hand, the difficulty of bubbles rising to the filter hole 401 along the airflow can be further increased, which is conducive to reducing the amount of bubbles at the filter hole 401 and reducing the influence of the rising liquid level in the cooking cavity 101 on the exhaust process of the exhaust assembly 300. On the other hand, the flow path of the gas in the cooking cavity 101 to the air inlet 301 can be prolonged, and the probability of bubble rupture during flow can be improved.
[0103] It can be understood that the side of the lid assembly 200 facing the pot bottom refers to the side of the lid assembly 200 facing the pot bottom when the lid assembly 200 covers the pot opening.
[0104] As shown in Figure 5 and Figure 10 in some examples, the direction of the air inlet 301 is intersected with the depth direction of the cooking cavity 101; and / or the direction of the filter hole 401 is intersected with the depth direction of the cooking cavity 101.
[0105] In the technical solution, the direction of the air inlet 301 can be intersected with the depth direction of the cooking cavity 101. On the one hand, the direction of the air inlet 301 can be different from the depth direction of the cooking cavity 101, thereby avoiding the direction with high pressure gradient in the cooking cavity 101, avoiding the bubbles or liquid in the cooking cavity 101 rapidly approaching the air inlet 301 during the rising process, and being conducive to prolonging the continuous exhaust time. On the other hand, it is also conducive to further improving the position height of the air inlet 301 and increasing the distance between the air inlet 301 and the liquid surface in the cooking cavity 101, so that the air inlet 301 is located at a height position with relatively low bubble amount. Therefore, based on the above arrangement of the technical solution, the distance between the air inlet 301 and the liquid surface can be increased, and the air inlet 301 can be more easily accessed to the gas with less bubble amount in the upper layer of the cooking cavity 101 during the exhaust pressure relief process, thereby further reducing the influence of the rising liquid level in the cooking cavity 101 on the exhaust pressure relief, prolonging the continuous exhaust time of the exhaust assembly 300, and reducing the risk of liquid overflow of the exhaust assembly 300.
[0106] In the technical solution, the conducting direction of the filter hole 401 can be arranged to intersect the depth direction of the cooking cavity 101, so as to form a difference between the conducting direction of the filter hole 401 and the depth direction of the cooking cavity 101, thereby avoiding the direction with a high pressure gradient in the cooking cavity 101, avoiding the bubbles or liquid in the cooking cavity 101 from rapidly approaching the filter hole 401 in the rising process, and facilitating to prolong the continuous exhaust time. On the other hand, it is also beneficial to further increase the position height of the filter hole 401, increase the distance between the filter hole 401 and the liquid level in the cooking cavity 101, so as to place the filter hole 401 at a height position with a relatively low amount of bubbles. Thus, based on the foregoing arrangement of the technical solution, it is beneficial to increase the distance between the filter hole 401 and the liquid level, and the filter hole 401 can be more easily accessed to the gas with a small amount of bubbles in the upper layer of the cooking cavity 101 during the exhaust and pressure relief process, further reducing the influence of the liquid level height rising in the cooking cavity 101 on the exhaust and pressure relief, prolonging the continuous exhaust time of the exhaust assembly 300, and reducing the risk of liquid overflow of the exhaust assembly 300.
[0107] It can be understood that in the technical solution, the conducting directions of the air inlet 301 and the filter hole 401 both intersect the depth direction of the cooking cavity 101.
[0108] In some feasible examples, the air inlet 301 is perpendicular to the depth direction of the cooking cavity 101; and / or the conducting direction of the filter hole 401 is perpendicular to the depth direction of the cooking cavity 101.
[0109] As shown in Figure 4 and Figure 5 in some examples, along the depth direction of the cooking cavity 101, the distance H2 between the air inlet 301 and the pot cover assembly 200 is less than or equal to 15 mm; and / or
[0110] along the depth direction of the cooking cavity 101, the distance between the filter hole 401 and the pot cover assembly 200 is less than or equal to 15 mm; and / or
[0111] The pot body assembly 100 is formed with a highest liquid level mark, and along the depth direction of the cooking cavity 101, the distance H1 between the air inlet 301 and the highest liquid level mark is greater than or equal to 65 mm.
[0112] In the technical solution, the distance H2 between the air inlet 301 and the pot cover assembly 200 in the depth direction of the cooking cavity 101 can be less than or equal to 15 mm. The distance H2 can be the maximum distance between the air inlet 301 and the pot cover assembly 200 in the depth direction of the cooking cavity 101. Based on the above setting, the position of the air inlet 301 relative to the bottom of the pot body assembly 100 can be higher. In the process of exhaust pressure relief, on the one hand, the difficulty of the bubbles rising to the air inlet 301 along the airflow can be increased, and on the other hand, the flow path of the gas in the cooking cavity 101 to the air inlet 301 can be prolonged, and the breaking probability of the bubbles in the flow process can be improved.
[0113] In the technical solution, the distance between the filter hole 401 and the pot cover assembly 200 in the depth direction of the cooking cavity 101 can be less than or equal to 15 mm. The distance can be the maximum distance between the filter hole 401 and the pot cover assembly 200 in the depth direction of the cooking cavity 101. Based on the above setting, the position of the filter hole 401 relative to the bottom of the pot body assembly 100 can be higher. In the process of exhaust pressure relief, on the one hand, the difficulty of the bubbles rising to the filter hole 401 along the airflow can be increased, and on the other hand, the flow path of the gas in the cooking cavity 101 to the air inlet 301 can be prolonged, and the breaking probability of the bubbles in the flow process can be improved.
[0114] In the technical solution, the inner wall of the pot body assembly 100 can be formed with a highest liquid level mark. The highest liquid level mark can be located in the cooking cavity 101, and used to prompt the maximum liquid injection height when the user injects liquid into the cooking cavity 101. Correspondingly, the distance H1 between the air inlet 301 and the highest liquid level mark in the depth direction of the cooking cavity 101 can be greater than or equal to 65 mm. The distance H1 can be the minimum distance between the air inlet 301 and the highest liquid level mark in the depth direction of the cooking cavity 101. Based on the above setting, the air inlet 301 and the liquid surface in the cooking cavity 101 can be kept at a large distance during cooking. In the process of exhaust pressure relief, the liquid surface can be prevented from rising to the air inlet 301 quickly, which is beneficial to further reduce the influence of the liquid level height rising on the exhaust effect and reduce the probability of liquid overflow when the exhaust assembly 300 exhausts.
[0115] It can be understood that in actual application, the three distance limitations of the technical solution can be all used or any one or any two of them can be used, which is not limited here.
[0116] In some feasible examples, the distance H2 between the aforementioned air inlet 301 and the aforementioned pot cover assembly 200 along the depth direction of the aforementioned cooking cavity 101 is less than or equal to 10 mm; and / or
[0117] The distance between the aforementioned filter hole 401 and the aforementioned pot cover assembly 200 along the depth direction of the aforementioned cooking cavity 101 is less than or equal to 10 mm; and / or
[0118] The aforementioned pot body assembly 100 is formed with a highest liquid level mark, and the distance H1 between the aforementioned air inlet 301 and the aforementioned highest liquid level mark along the depth direction of the aforementioned cooking cavity 101 is greater than or equal to 65 mm.
[0119] As shown in Figures 5 to 9 and Figure 11 In some examples, the pressure cooking appliance further comprises an anti-overflow assembly 500 connected to the aforementioned pot cover assembly 200, the aforementioned anti-overflow assembly 500 is formed with a flow hole 501, and a transition cavity 502 is formed between the aforementioned anti-overflow assembly 500 and the aforementioned pot cover assembly 200. The aforementioned filter hole 401 is communicated between the aforementioned transition cavity 502 and the aforementioned air inlet 301, and the aforementioned flow hole 501 is used to communicate between the aforementioned transition cavity 502 and the aforementioned cooking cavity 101.
[0120] In this technical solution, the pressure cooking appliance can further comprise an anti-overflow assembly 500 connected to the pot cover assembly 200, and a transition cavity 502 is formed between the anti-overflow assembly 500 and the pot cover assembly 200. It can be understood that the anti-overflow assembly 500 is located between the aforementioned transition cavity 502 and the aforementioned cooking cavity 101, the air inlet 301 of the exhaust assembly 300 can be communicated with the transition cavity 502 through the filter hole 401, and the anti-overflow assembly 500 has a flow hole 501, and the aforementioned transition cavity 502 can be communicated with the cooking cavity 101 through the flow hole 501. Based on the above arrangement, when the exhaust assembly 300 exhausts, the gas in the cooking cavity 101 can flow to the air inlet end of the exhaust assembly 300 through the transition cavity 502 and the filter hole 401 in turn, and can contact the anti-overflow assembly 500 and the anti-clogging assembly 400 when flowing through the flow hole 501 and the aforementioned filter hole 401 respectively, and the gas bubbles carried by the gas are also easy to contact the pot cover assembly 200 and the anti-clogging assembly 400 at the corresponding positions, thereby increasing the probability of bubble rupture, and further prolonging the path length of the gas in the cooking cavity 101 flowing to the aforementioned air inlet 301, increasing the probability of natural rupture of bubbles during the flow process, reducing the possibility of bubbles gathering or entering the air inlet end of the exhaust assembly 300, ensuring the exhaust effect of the exhaust assembly 300 and reducing the risk of liquid produced after the rupture of bubbles overflowing through the exhaust assembly 300, reducing the cleaning burden of the pressure cooking appliance, and improving the user experience of the product.
[0121] As shown in Figure 5 , Figure 8and Figure 9 As shown, in some examples, the aforementioned anti-overflow component 500 includes: an anti-overflow plate 510 having the aforementioned flow hole 501; a handle 520 passing through the aforementioned anti-overflow plate 510, one end of the aforementioned handle 520 being detachably connected to the aforementioned lid assembly 200; wherein, when the aforementioned handle 520 is connected to the aforementioned lid assembly 200, the aforementioned anti-overflow plate 510 and the aforementioned lid assembly 200 form the aforementioned transition cavity 502.
[0122] In this technical solution, the aforementioned anti-overflow component 500 may include an anti-overflow plate 510 and a handle 520. The handle 520 passes through the anti-overflow plate 510 and is detachably connected to the lid assembly 200. When the handle 520 is connected to the lid assembly 200, the anti-overflow plate 510 and the lid assembly 200 form the aforementioned transition cavity 502. Correspondingly, the aforementioned overflow hole 501 is opened in the anti-overflow plate 510. Based on the aforementioned configuration, the ease of cleaning the anti-overflow plate 510 and the transition cavity 502 can be improved, further enhancing the cleanliness and hygiene of the pressure cooking appliance and improving the user experience of the product.
[0123] like Figure 5 As shown, in some examples, when the aforementioned exhaust assembly 300 includes a hanger 320, the hanger 320 is arranged corresponding to the center of the aforementioned overflow baffle 510, the aforementioned overflow hole 501 is arranged near the edge of the aforementioned overflow baffle 510, and the aforementioned handle 520 is detachably connected to the aforementioned hanger 320; and / or
[0124] The sum of the conducting areas of the aforementioned flow passages 501 is greater than or equal to the conducting area of the aforementioned air inlet 301; and / or
[0125] The aforementioned flow-through holes 501 are open along the depth direction of the aforementioned cooking cavity 101. In a projection plane perpendicular to the direction of the flow-through holes 501, the ratio of the sum of the projected areas of the aforementioned flow-through holes 501 to the projected area of the aforementioned spill-proof plate 510 is greater than or equal to 0.1% and less than or equal to 0.5%; and / or
[0126] One end of the aforementioned overflow hole 501 is located on the side of the aforementioned anti-overflow plate 510 near the bottom of the aforementioned pot.
[0127] In this technical solution, the aforementioned handle 520 can be connected to the lid assembly 200 via the hanging shaft 320 of the exhaust assembly 300, which helps to improve the structural compactness of the pressure cooking appliance. Correspondingly, the aforementioned hanging shaft 320 can be arranged in the middle of the aforementioned anti-overflow plate 510, and the aforementioned overflow hole 501 can be opened at the edge of the anti-overflow plate 510, thereby extending the flow path of gas in the transition chamber 502, increasing the probability of bubbles bursting in the transition chamber 502, and further reducing the risk of liquid overflow from the exhaust assembly 300.
[0128] In the technical solution, the sum of the flow-through areas of the flow-through holes 501 can be greater than or equal to the flow-through area of the air inlet 301, thereby facilitating the guarantee of the flow rate of the exhaust assembly 300 during exhaust, and providing guarantee for the exhaust pressure relief efficiency of the pressure cooking appliance.
[0129] In the technical solution, the flow-through holes 501 can be arranged to flow through along the depth direction of the cooking cavity 101, and the size of the flow-through holes 501 can be constrained so that, in the projection plane perpendicular to the flow-through direction of the flow-through holes 501, the ratio of the sum of the projection areas of the flow-through holes 501 to the projection area of the overflow plate 510 is greater than or equal to 0.1% and less than or equal to 0.5%. It can be understood that the number of the flow-through holes 501 can be greater than or equal to 1. When the number of the flow-through holes 501 is one, the sum of the flow-through areas of the flow-through holes 501 is the flow-through area of the flow-through hole 501. Based on the foregoing arrangement, the overall flow-through area of the flow-through holes 501 can be avoided to be too large or too small, thereby on the one hand, the overall flow rate of the flow-through holes 501 during exhaust pressure relief can be avoided to be too large, the liquid level rising rate in the cooking cavity 101 can be reduced, thereby the amount of bubbles passing through the flow-through holes 501 is reduced, which is beneficial to reduce the probability of liquid overflow of the exhaust assembly 300 and prolong the continuous exhaust time of the exhaust assembly 300; on the other hand, the overall flow rate of the flow-through holes 501 during exhaust pressure relief can also be avoided to be too small, thereby guaranteeing the exhaust pressure relief efficiency of the pressure cooking appliance.
[0130] In the technical solution, one end of the flow-through hole 501 can be located on the side of the overflow plate 510 close to the bottom of the pot, thereby the position of one end of the flow-through hole 501 on the overflow plate 510 can be relatively low, and the liquid in the transition cavity 502 can be conveniently returned to the cooking cavity 101 through the flow-through hole 501, which is beneficial to avoid the accumulation of a large amount of liquid in the transition cavity 502, and can further reduce the risk of the air inlet 301 of the exhaust assembly 300 entering liquid or bubbles while guaranteeing the cleanliness and hygiene of the transition cavity 502.
[0131] It can be understood that in actual application, the various limitations on the flow-through holes 501 in the technical solution can be simultaneously adopted or any one or any two or any three of them can be adopted, which is not limited herein.
[0132] Exemplarily, in the projection plane perpendicular to the flow-through direction of the flow-through holes 501, the ratio of the sum of the projection areas of the flow-through holes 501 to the projection area of the overflow plate 510 can be, but is not limited to, 0.15%, 0.17%, 0.2%, 0.3%, or 0.45%, and the like.
[0133] In some feasible examples, the conductive area of each of the aforementioned flow holes 501 can be less than or equal to 25 mm 2 , for example, can be 5 mm 2 , 15 mm 2 , or 23 mm 2 , etc.; the minimum width of the cross section of each of the aforementioned flow holes 501 can be greater than or equal to 3 mm, for example, can be 4 mm 2 , 5 mm 2 , or 6 mm 2 , etc., so that the liquid in the transition cavity 502 can be conveniently returned to the cooking cavity 101 through the flow holes 501, and the bubble breaking effect of the flow holes 501 can be facilitated.
