Description

Technical Field

[0001] The present invention relates to the technical field of kitchen utensils, and more specifically, to a sealing cover for a cooking container, and also to a food processor including the above-mentioned sealing cover for a cooking container. Background Art

[0002] A food processor belongs to one of the food processors, and has functions such as food stirring, crushing, and even heating and steaming. In particular, it can meet the requirements of baby and elderly people for supplementary food processing and cooking, and thus is recognized by more and more consumers.

[0003] Many kitchen appliances for cooking viscous foods usually cause foam to overflow due to the generation of foam, and the cooking requires a small exhaust hole, resulting in the foam generated during boiling overflowing from the gap of the lid. Under atmospheric pressure, the foam will break, causing the liquid to splash and polluting the surrounding utensils.

[0004] In summary, how to effectively solve the problem of exhaust pollution of surrounding equipment at the exhaust port of the current cooking container is an urgent problem for those skilled in the art at present. Summary of the Invention

[0005] In view of this, the first object of the present invention is to provide a sealing cover for a cooking container, which can effectively solve the problem of exhaust pollution of surrounding equipment at the exhaust port of the current cooking container. The second object of the present invention is to provide a food processor including the above-mentioned sealing cover for a cooking container.

[0006] In order to achieve the above first object, the present invention provides the following technical solution:

[0007] A sealing cover for a cooking container includes an inner cover for sealingly connecting with the opening of the container body. A liquid storage chamber is provided at the upper part of the inner cover. The liquid storage chamber is provided with a gas guiding channel communicating with the inner side of the inner cover. A pressure relief port for making the internal pressure the same as the external pressure is provided at the upper part of the liquid storage chamber.

[0008] In the sealed cover of this cooking container, during application, the inner cover is hermetically connected to the opening of the container body. As cooking progresses, the air pressure inside the inner cover gradually increases until the bubbles surrounded by the liquid emerge from the outlet of the air guiding channel and enter the liquid storage chamber. Due to the presence of the pressure relief opening in the liquid storage chamber, the air pressure in the liquid storage chamber is at an atmospheric pressure environment. As a result, the bubbles entering the liquid storage chamber are depressurized and then burst. The splashing liquid droplets formed by the bursting of the bubbles are effectively blocked by the wall of the liquid storage chamber, thereby preventing liquid splashing. At the same time, the liquid storage chamber collects the liquid and prevents it from flowing randomly. Therefore, in this cooking container, by arranging the liquid storage chamber outside the exhaust hole of the inner cover, through the liquid storage chamber, not only is the liquid splashing caused by the bursting of bubbles effectively avoided, but also the collected liquid is stored, preventing the liquid from flowing randomly, and thus effectively avoiding the pollution of other devices by the cooking container. In summary, the sealed cover of this cooker can effectively solve the problem of exhaust pollution of surrounding devices by the exhaust port of the current cooking container.

[0009] Preferably, a labyrinth structure is formed at the pressure relief opening.

[0010] Preferably, a liquid storage groove is provided at the upper part of the inner cover. The notch of the liquid storage groove is covered with an outer cover. The outer cover is detachably connected to the inner cover and forms the liquid storage chamber in combination with the liquid storage groove. The outlet of the air guiding channel is provided in the middle of the liquid storage groove. A pressure relief opening is formed between the edge of the outer cover and the edge of the liquid storage groove.

[0011] Preferably, from the middle to the periphery of the bottom of the liquid storage groove, it gradually slopes downward.

[0012] Preferably, the four peripheral edges of the outer cover have an annular downward convex baffle. The air guiding channel is located inside the downward convex baffle. The outside of the downward convex baffle is located inside the wall of the liquid storage groove and forms an annular pressure relief opening therebetween. The lower side of the downward convex baffle is lower than the outlet of the air guiding channel.

[0013] Preferably, the outer cover includes a cover plate and the downward convex baffle provided on the lower side of the cover plate. The cover plate is further provided with an extension part outside the downward convex baffle, and the extension part covers the gap between the edge of the liquid storage groove notch and the downward convex baffle.

[0014] Preferably, a through hole is provided in the middle of the liquid storage groove. The middle part inside the outer cover has a tubular support column. The lower end of the tubular support column is sleeved and lapped on the through hole. An air vent groove forming the air guiding channel is opened at the lower end of the tubular support column between the hole end of the through hole.

[0015] Preferably, an annular bulge is provided at the hole end of the through hole to limit the lower end of the tubular support column.

[0016] Preferably, the through hole is a round hole, and the tubular support column is a round tube column.

[0017] To achieve the second above-mentioned purpose, the present invention further provides a complementary food machine, which includes any one of the above-mentioned cooking container sealing covers, and further includes a container body, and the lower side of the cooking container sealing cover is hermetically connected to the container body. Since the above-mentioned cooking container sealing cover has the above-mentioned technical effects, the complementary food machine with this cooking container sealing cover should also have corresponding technical effects.

[0029] Please refer to Figures 1 - 5 , Figure 1 which is a schematic cross-sectional structure diagram of the seal of the cooking container provided by the embodiment of the present invention; Figure 2 which is a three-dimensional structure diagram of the half-sectional structure of the seal of the cooking container provided by the embodiment of the present invention; Figure 3 which is a schematic inner cover structure diagram of the seal of the cooking container provided by the embodiment of the present invention; Figure 4 which is a schematic outer cover structure diagram of the seal of the cooking container provided by the embodiment of the present invention; Figure 5 which is a schematic structure diagram of the food processor provided by the embodiment of the present invention.

[0030] In a specific embodiment, this embodiment provides a sealing cover for a cooking container to be used in cooperation with the container body 5 of the cooking container. Specifically, the cooking container can be appliances such as an electric rice cooker, a pressure cooker, a food processor, etc.

[0031] Specifically, the cooking container is provided with an inner cover 1 for sealing connection with the opening of the container body 5. The sealing connection between the inner cover 1 and the opening of the container body 5 can refer to the prior art, such as the sealing connection between the lid of an electric rice cooker and the lower container body, or the sealing connection between the lid of a pressure cooker and the lower container body, or the sealing connection between the lid of a food processor and the lower container body. The sealing is mainly by rotational snap connection, and a rubber sealing ring is provided therebetween.

[0032] A liquid storage chamber is provided above the inner cover 1, and a gas guide channel 3 communicating with the inner side of the inner cover 1 is provided in the liquid storage chamber. The function of the gas guide channel 3 is to exhaust the gas inside the cavity of the cooking container. Generally, in order to avoid too fast pressure relief in the cavity and large loss of gas moisture, a small gas guide channel 3 is provided to be used as an exhaust hole. For a food processor and an electric rice cooker, generally, the area of the exhaust hole is equivalent to the area of a circle with a diameter between 2 mm and 5 mm. During the cooking process, when the gas inside the cavity is discharged from the gas guide channel 3, a series of small bubbles will be discharged.

[0033] Because the above-mentioned exhaust channel is provided in the liquid storage chamber, after the bubbles and gas are discharged from the exhaust channel, these bubbles and gas will enter the liquid storage chamber. The size of the liquid storage chamber is consistent with the amount of bubbles in the cooking container to ensure that the liquid storage chamber is sufficient to store the bubbles discharged from the ventilation channel.

[0034] A pressure relief port 4 for making the internal air pressure the same as the external air pressure is provided at the upper part of the liquid storage chamber. The cross-section of the pressure relief port 4 should be much larger than that of the air guide channel 3 so that the internal air pressure of the liquid storage chamber is the same as the external atmospheric pressure. First, through the liquid storage chamber, liquid splashing caused by the rupture of bubbles in the pressure relief environment can be effectively avoided. Second, the pressure relief port 4 can ensure a rapid reduction in the internal air pressure of the liquid storage chamber to ensure the rapid rupture of bubbles and their aggregation into liquid, thereby ensuring that the capacity of the liquid storage chamber meets the usage requirements. The pressure relief port 4 is set to ensure that the internal air pressure of the liquid storage chamber is consistent with or close to the external air pressure.

[0035] In this cooking container sealing cover, during application, the inner cover 1 is hermetically connected to the opening of the container body 5. As cooking progresses, the air pressure inside the inner cover 1 gradually increases until the bubbles surrounded by liquid emerge from the outlet of the air guide channel 3 and enter the liquid storage chamber. Due to the existence of the pressure relief port 4 in the liquid storage chamber, the air pressure in the liquid storage chamber is in an atmospheric pressure environment, so that the bubbles entering the liquid storage chamber are depressurized and then rupture. The splashing liquid beads formed by the rupture of the bubbles will be effectively blocked by the wall of the liquid storage chamber, thereby preventing liquid splashing. At the same time, the liquid storage chamber collects the liquid and prevents it from flowing randomly. Therefore, in this cooking container, by providing a liquid storage chamber outside the exhaust hole of the inner cover 1, not only can liquid splashing caused by the rupture of bubbles be effectively avoided, but also the collected liquid can be stored to prevent the liquid from flowing randomly, thereby effectively avoiding the pollution of other devices by the cooking container. In summary, this cooking utensil sealing cover can effectively solve the problem of exhaust pollution of the surrounding devices by the exhaust port of the current cooking container.

[0036] Furthermore, when the bubbles in the liquid storage chamber rupture, the gas will splash in all directions. To fully and effectively prevent the splashing liquid from splashing outside the liquid storage chamber through the pressure relief port 4, it is preferably provided with a labyrinth structure at the pressure relief port 4 to block the small liquid beads flying towards the pressure relief port 4 back through the labyrinth structure. At the same time, the labyrinth structure does not affect gas transmission, thereby fully ensuring internal pressure relief. The labyrinth structure mainly forms a tortuous channel at the pressure relief port 4 to prevent the liquid beads inside the liquid storage chamber from splashing out in a straight line. The labyrinth structure can refer to the labyrinth channels in the prior art.

[0037] Furthermore, to facilitate the cleaning of the liquid storage chamber, it is preferably provided with a liquid storage tank 11 at the upper part of the inner cover 1, and the upper end of the liquid storage tank 11 is formed with an open notch. Correspondingly, an outer cover 2 is covered on the notch of the liquid storage tank 11, and the outer cover 2 is detachably connected to the inner cover 1, such as lapping, clamping, and threaded connection. The above-mentioned liquid storage chamber is formed by combining the outer cover 2 and the liquid storage tank 11, that is, the inner side wall of the outer cover 2, that is, the lower side wall, and the wall and bottom of the liquid storage tank 11 are all the walls of the liquid storage chamber.

[0038] An air guide channel 3 is provided at the bottom of the liquid storage tank 11, and the air outlet of the air guide channel 3 may be provided at the bottom edge of the liquid storage tank 11 or in the middle of the liquid storage tank 11. When the air outlet of the air guide channel 3 is provided in the middle of the liquid storage tank 11, it is preferred that a pressure relief port 4 is formed between the edge of the outer cover 2 and the groove edge of the liquid storage tank 11, so that the pressure relief port 4 is arranged away from the air guide channel 3.

[0039] Furthermore, in order to prevent the liquid in the liquid storage tank 11 from flowing back to the air guide channel 3 and then blocking the air guide channel 3, and at the same time to prevent it from being blown by the high-pressure gas in the air guide channel 3 and splashing again, it is preferred that the bottom of the liquid storage tank 11 is gradually tilted downward from the air outlet of the air guide channel 3 to the surroundings, so that the liquid flowing out of the air outlet of the air guide channel 3 flows to the surroundings, thereby preventing it from flowing back to the air outlet of the air guide channel 3. Correspondingly, when the air outlet of the air guide channel 3 is set in the middle of the bottom of the liquid storage tank 11, the corresponding bottom of the liquid storage tank 11 is gradually tilted downward from the middle to the surroundings, so that the bottom of the liquid storage tank 11 gradually bulges from the surroundings to the middle to form a boss shape.

[0040] In practical applications, bubbles generally burst at the outlet of the air guide channel 3. Therefore, in order to more effectively prevent the splashing gas caused by the bursting of bubbles from flying out from the pressure relief port 4, it is preferred that the surrounding edges of the outer cover 2 have an annular lower convex baffle 22, and at this time, the air guide channel 3 is located on the inner side of the lower convex baffle 22, and the outer side of the lower convex baffle 22 is located on the inner side of the wall of the liquid storage tank 11 and an annular pressure relief port 4 is formed therebetween, and the lower side of the lower convex baffle 22 is lower than the outlet of the air guide channel 3, but is significantly higher than the surrounding bottom of the liquid storage tank 11, so as to ensure that the liquid stored in the liquid storage tank 11 will not block the pressure relief port 4. The lower convex baffle 22 effectively prevents gas from flying out directly from the pressure relief port 4.

[0041] Furthermore, in order to avoid gas splashing, the outer cover 2 preferably includes a cover plate 21 and a lower convex baffle plate 22 arranged on the lower side of the cover plate 21, wherein the cover plate 21 is also provided with an extension portion 23 on the outer side of the lower convex baffle plate 22, wherein the extension portion 23 covers the gap between the groove edge of the liquid storage tank 11 and the lower convex baffle plate 22, so as to redirect the direction of the pressure relief port 4 again through the extension portion 23.

[0042] Further, for the convenience of cleaning, it is preferred that a through hole 12 is provided in the middle of the liquid storage tank 11, and a tubular support column 24 is provided in the middle of the inner side of the outer cover 2, and a tube cover at the lower end of the tubular support column 24 is provided and overlapped on the outer end of the through hole 12, wherein the lower end of the tubular support column 24 is provided with a venting groove 25 that forms the air guide channel 3 between the hole end of the through hole 12. The tubular support column 24 can be detached from the inner cover 1, and after separation, because they are all macroporous structures, they are very convenient to clean.

[0043] Specifically, the cover plate 21 can be a circular flat plate, and a circular ring-shaped downward convex baffle 22 is arranged on the lower side of the circular flat plate. The downward convex baffle 22 is integrally and hermetically connected to the upper side of the circular flat plate. The tubular support column 24 is located inside the downward convex baffle 22 and in the middle of the circular flat plate. The upper end of the tubular support column 24 is tightly connected to the circular flat plate, and preferably a plurality of ventilation grooves 25 are transversely opened at the lower end. The ventilation grooves 25 can be arc-shaped grooves. Specifically, the through hole 12 can be a round hole, or of course it can also be a square hole. Correspondingly, the tubular support column 24 is a circular tube column. The liquid storage tank 11 can be a cylindrical tank, and the diameter of the tank wall is larger than the outer diameter of the downward convex baffle 22 to ensure a pressure relief gap is formed therebetween. When the tubular support column 24 is lapped on the bottom of the liquid storage tank 11 and abuts against the bottom of the liquid storage tank 11, the cover plate 21 is arranged higher than the notch of the liquid storage tank 11 at this time.

[0044] Preferably, the lower end of the tubular support column 24 is lapped outside the outer end of the through hole 12, which is convenient for detachment. At the same time, it is convenient for cleaning. In order to better stabilize the position of the outer cover 2, preferably an annular bulge 13 is provided at the hole end of the through hole 12 to limit the lower end of the tubular support column 24. The arc-shaped bulge surrounds the lower end of the tubular support column 24 to form an enclosure. However, it should be ensured that the air outlet end of the ventilation groove 25 is open to ensure ventilation into the liquid storage bin.

The lower side of the cooking container sealing cover is hermetically connected to the container body.
