Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of small household appliances, in particular to a steamer and a cooking appliance with the same. BACKGROUND

[0002] In the process of cooking rice by the cooking device, the washed rice is first put into the cooking device, and water is added into the pot, usually the water level is about 20mm higher than the rice surface, so that the cooked rice will not be scorched and the rice can be cooked thoroughly.

[0003] The cooking device in the related art cooks the rice by immersing the rice in water, due to the direct contact between the water and the rice, the cooked rice contains a large amount of starch, which will be quickly converted into sugar after being absorbed into the human body, and cannot meet the demand of people with diabetes, high blood pressure and high blood pressure for low-sugar staple food.

[0004] In order to solve the above problems, a cooking device is provided in the related art. The cooking device includes a pot and a steamer located in the pot. The rice is put into the steamer, and water is added into the pot to immerse the rice in the steamer. During the heating process of the cooking device, the rice absorbs water and becomes semi-cooked rice, and the water becomes rice soup. When the liquid level of the rice soup is lower than the steamer and boils, the boiling rice soup can enter the steamer through the gap between the side wall of the steamer and the side wall of the pot and the overflow hole of the side wall of the steamer to continue heating the rice. In the process of climbing along the side wall of the steamer, the water pressure of the boiling rice soup will gradually decrease, and the boiling rice soup can only flow into the steamer along the inner wall of the steamer to dissolve the starch in a small amount of rice near the inner wall, while most of the rice in the middle of the steamer cannot contact with the rice soup, which makes the effect of dissolving starch poor, and the sugar content in the cooked rice is high, which cannot meet the demand of people who need to intake low-sugar staple food. SUMMARY

[0005] The main purpose of the present application is to provide a steamer and a cooking appliance with the same, to solve the problem of poor effect of dissolving starch in the cooking device in the related art.

[0006] In order to achieve the above purpose, according to one aspect of the present application, a steamer is provided, comprising: a steamer bottom wall, the steamer bottom wall is provided with an overflow hole; a steamer side wall connected with the steamer bottom wall; a protruding structure upwardly protruding at the gap of the steamer bottom wall and located inside the steamer side wall, the protruding structure comprising a protruding side wall and a protruding top wall, a drainage space is formed between the protruding top wall and the protruding side wall, the protruding side wall is a closed structure, and the protruding top wall is provided with a drainage hole communicating with the drainage space; wherein the material of the steamer is plastic or metal.

[0007] The application has the advantages that when the steamer is used, rice is put into the steamer, and water is added into the container of the cooking appliance. During the heating process of the cooking appliance, the rice absorbs water and becomes semi-cooked rice, and the water becomes rice soup. When the liquid level of the rice soup is lower than the lowest point of the steamer, the rice soup continues to boil. Since the drainage space can form a narrow space, the boiling rice soup is squeezed into the drainage space and directly enters the steamer through the drainage holes of the protruding structure. Compared with the boiling rice soup climbing along the side wall of the steamer in the related art, the water pressure of the boiling rice soup in the application basically does not decrease, and since the protruding side wall is a closed structure, more rice soup can be accumulated in the drainage space, the water pressure is increased, the rice soup entering the steamer can spray a high water column, the water column can cover almost all the rice in the steamer during falling, and the rice grains are continuously scoured, the starch in the rice is fully dissolved, the effect of dissolving the starch is improved, and after the starch in the rice is scoured, the starch flows back to the container of the cooking appliance with the rice soup. In this way, after the starch in the rice is repeatedly scoured, the cooked rice contains less sugar, which can meet the needs of people who need to intake low-sugar staple food. Therefore, the application effectively solves the problem of poor starch dissolving effect of the cooking device in the related art.

[0008] Further, the diameter of the drainage hole is greater than or equal to the diameter of the overflow hole. In the above structure, when the boiling rice soup is squeezed into the drainage space, the water column formed by the boiling rice soup directly entering the steamer through the drainage hole is uniform and more, so that the rice soup can uniformly cover all the rice in the steamer. During the continuous scouring of the rice soup on the rice grains, the effect of the uniform and sufficient rice soup on the starch in the rice is better.

[0009] Further, the drainage hole is a plurality of drainage holes, the plurality of drainage holes form a plurality of hole groups, the plurality of drainage holes in each hole group are arranged along the radial direction of the protruding top wall, and the ratio of the spacing between the adjacent two hole groups to the diameter of the drainage hole is between 1.5 and 3.5. In the above structure, enough rice soup can be sprayed from the plurality of drainage holes, so that the effect of the rice soup on the starch in the rice is better, and the heating of the rice is more uniform.

[0010] Further, the ratio of the diameter of the drainage hole to the diameter of the overflow hole is in the range of 2 / 1 to 1 / 1. In the above structure, when the boiling rice soup is squeezed into the drainage space, the water column formed by the boiling rice soup directly entering the steamer through the drainage hole is uniform and more, so that the uniform and more rice soup can cover all the rice in the steamer. During the continuous scouring of the rice soup on the rice grains, the effect of the uniform and sufficient rice soup on the starch in the rice is better, and it is beneficial to uniformly heat the rice.

[0011] Further, in order to make the cooking utensil produce rice with good taste and good cooking, the diameter of the drain hole is in the range of 0.5mm to 20mm, and / or the diameter of the overflow hole is in the range of 0.5mm to 10mm. The above structure enables the people with low sugar intake to obtain rice with good taste and good cooking.

[0012] Further, the overflow hole is multiple, and the multiple overflow holes are uniformly distributed on the bottom wall of the steamer. In this way, after the starch in the rice is washed away, the starch is uniformly returned to the container of the cooking utensil with the rice soup from the multiple overflow holes, thereby improving the washing effect of the rice soup on the rice.

[0013] Further, the ratio between the height of the convex structure and the height of the side wall of the steamer is in the range of 2 / 5 to 4 / 5. The above structure, on the one hand, makes the amount of rice in the steamer appropriate, and on the other hand, ensures that the area covered by the water column formed by the water column injection can completely cover the circumferential area of the bottom wall of the steamer.

[0014] Further, when the material of the steamer is plastic, in order to facilitate demolding, the convex structure is processed, and the convex structure gradually shrinks from bottom to top.

[0015] Further, the convex top wall is a flat structure or an arc-shaped plate structure. The convex top wall of the above structure enables the boiling rice soup to orderly gather at the drain hole before entering the drain hole, which is conducive to improving the water pressure of the boiling rice soup.

[0016] Further, in order to facilitate the connection of the convex structure and the bottom wall of the steamer, the convex structure and the bottom wall of the steamer are detachably connected.

[0017] Further, in order to facilitate processing and simple molding, the convex structure and the bottom wall of the steamer are fixedly connected or integrally formed.

[0018] Further, in order to facilitate the taking and placing of the steamer into the container of the cooking utensil, the steamer further comprises a turned-up edge arranged at the top of the side wall of the steamer.

[0019] Further, the side wall of the steamer is a closed structure. In the above structure, the boiling rice soup cannot enter the steamer from the side wall of the steamer, so that the boiling rice soup can be gathered in the drain space, which is conducive to improving the water pressure of the boiling rice soup.

[0020] According to another aspect of the present application, a cooking utensil is provided, comprising: a container; a steamer arranged in the container in a removable manner, and having a space between the bottom wall of the steamer and the bottom wall of the container, and the steamer is the above-mentioned steamer. Since the above-mentioned steamer can solve the problem of poor starch dissolving effect of the rice cooking device in the related art, the cooking utensil comprising the steamer has the same effect.

[0021] According to another aspect of the present application, there is provided a cooking appliance comprising: a container; a steamer, the steamer being the steamer as described above, the steamer being removably disposed in the container, the flange of the steamer being supported by the container, and the flange being sealingly engaged with the support surface of the container. As the flange is sealingly engaged with the support surface of the container, the rice soup cannot flow between the flange and the container, and the rice soup can only enter into the steamer through the drainage space of the steamer, thereby ensuring that there is sufficient rice soup to better rinse the starch in the rice.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting on the application or its applications or uses. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0033] like Figures 1 to 3 As shown, the steamer in this embodiment includes: a bottom wall 11, a side wall 12, and a raised structure 20. The bottom wall 11 has overflow holes 111. The side wall 12 is connected to the bottom wall 11. The raised structure 20 protrudes upward from the notch 112 in the bottom wall 11 and is located inside the side wall 12. The raised structure 20 includes a raised side wall 25 and a raised top wall 24, forming a drainage space 21 between the raised top wall 24 and the raised side wall 25. The raised side wall 25 is a closed structure, and the raised top wall 24 has drainage holes 22 communicating with the drainage space 21. The steamer is made of plastic or metal.

[0034] By using the technical solution of the embodiment, when the steamer is used, rice is put into the steamer, and water is added into the container of the cooking appliance. During the heating process of the cooking appliance, the rice absorbs water and becomes semi-cooked rice, and the water becomes rice soup. When the liquid level of the rice soup is lower than the lowest point of the steamer, the rice soup continues to boil, and because the drainage space 21 can form a narrow space, the boiling rice soup is squeezed into the drainage space 21 and directly enters the steamer through the drainage hole 22 of the protruding structure 20. Compared with the boiling rice soup climbing along the side wall of the steamer in the related art, the water pressure of the boiling rice soup in the technical solution of the embodiment is basically not reduced, and at the same time, because the protruding side wall 25 is a closed structure, more rice soup can be accumulated in the drainage space 21, the water pressure is increased, and the rice soup entering the steamer can spray a high water column, which can cover almost all the rice in the steamer during falling and continuously wash the rice, fully dissolving the starch in the rice, improving the effect of dissolving starch, and after the starch in the rice is washed away, the starch flows back into the container of the cooking appliance with the rice soup through the overflow hole 111. In this way, after repeatedly washing the starch in the rice, the cooked rice contains less sugar, which can meet the needs of people who want to intake low-sugar staple food. Therefore, the technical solution of the embodiment effectively solves the problem of poor effect of dissolving starch in the rice cooking device in the related art.

[0035] It should be noted that when the steamer is used, rice is put into the steamer, and water is added into the container of the cooking appliance. The water level does not necessarily have to immerse the rice in the steamer. The water level can be immersed, semi-immersed, or the water level can be located below the steamer.

[0036] It should be noted that the protruding side wall 25 being a closed structure can be understood as that the protruding side wall 25 has no hole communicating the inside and outside of the protruding side wall 25, that is, the fluid such as rice soup cannot pass through the protruding side wall 25.

[0037] In addition, in the embodiment, when the steamer is taken out of or placed into the container of the cooking appliance, the protruding structure 20 can form a holding part, which is convenient to operate and facilitates taking out or placing the steamer.

[0038] In order to facilitate processing and easy molding, the material of the steamer in the embodiment is plastic. Of course, in other embodiments not shown in the drawings, the material of the steamer is metal. The plastic is preferably PP (polypropylene). The metal is preferably stainless steel or aluminum.

[0039] As Figure 1 and Figure 2As shown, the diameter of the drain hole 22 is equal to the diameter of the flow hole 111. This ensures that when boiling rice water is forced into the drain space 21, the volume of water forming a jet directly entering the steamer from the drain hole 22 is more uniform, allowing the rice water to evenly cover all the rice in the steamer. As the rice water continuously washes over the rice grains, the effect of washing away the starch in the rice is more even. Of course, the diameter of the drain hole 22 is larger than the diameter of the flow hole 111. This also ensures that when boiling rice water is forced into the drain space 21, the volume of water forming a jet directly entering the steamer from the drain hole 22 is greater, allowing more rice water to cover all the rice in the steamer. As the rice water continuously washes over the rice grains, the effect of sufficient rice water washing away the starch in the rice is even better.

[0040] like Figure 1 and Figure 2 As shown, there are multiple drain holes 22, forming multiple hole groups. Within each hole group, the drain holes 22 are arranged radially along the raised top wall 24. The ratio of the distance between two adjacent hole groups to the diameter of the drain hole 22 is between 1.5 and 3.5. This allows sufficient rice water to be sprayed from the multiple drain holes 22, improving the rice water's effectiveness in rinsing the starch from the rice and ensuring more even heating of the rice. The ratio of the distance between two adjacent hole groups to the diameter of the drain hole 22 is preferably 2 or 3. Of course, in other embodiments not shown in the figures, the number of drain holes can also be single, which further increases the amount of rice water sprayed from multiple drain holes, resulting in a higher water column and improving the rice water's effectiveness in rinsing the starch from the rice.

[0041] like Figure 1 and Figure 2 As shown, the ratio of the diameter of the drain hole 22 to the diameter of the flow hole 111 is in the range of 2 / 1 to 1 / 1. This ensures that when boiling rice water is forced into the drain space 21, the volume of water forming a jet directly entering the steamer from the drain hole 22 is more uniform and abundant, allowing more rice water to evenly and comprehensively cover all the rice in the steamer. As the rice water continuously washes over the rice grains, the uniform and sufficient amount of rice water effectively washes away the starch in the rice and promotes even heating of the rice.

[0042] like Figure 2As shown, when the number of the drain holes 22 and the number of the overflow holes 111 are both multiple, in order to enable the cooking utensil to obtain cooked rice with good taste, the inventors have tested the cooked rice and found that when the diameter of the drain hole 22 and the diameter of the overflow hole 111 are within the range of greater than 0.1 mm and less than 0.5 mm, the upper layer of the cooked rice is dry, the overall taste is hard, and there is a phenomenon of undercooking; when the diameter of the drain hole 22 and the diameter of the overflow hole 111 are within the range of 0.5 mm to 3 mm, the upper layer of the cooked rice is slightly dry, and the overall taste is relatively hard; when the diameter of the drain hole 22 and the diameter of the overflow hole 111 are within the range of 3.5 mm to 6 mm, the overall taste of the cooked rice is soft and glutinous, and the taste is moderate; when the diameter of the drain hole 22 and the diameter of the overflow hole 111 are within the range of 6.5 mm to 10 mm, the overall taste of the cooked rice is slightly soft; and when the diameter of the drain hole 22 and the diameter of the overflow hole 111 are greater than 10 mm, the upper layer of the cooked rice is too soft, the overall taste is soft and rotten, and the taste is poor. Therefore, through the above test, it is known that the diameter of the drain hole 22 of the present application is within the range of 0.5 mm to 10 mm, and the diameter of the overflow hole 111 is within the range of 0.5 mm to 10 mm. People who intake low-sugar staple food can obtain cooked rice with good taste. Preferably, the diameter of the drain hole 22 is 2 mm, 4 mm, 6 mm or 8 mm; and the diameter of the overflow hole 111 is 2 mm, 4 mm, 6 mm or 8 mm.

[0043] Of course, in other embodiments not shown in the figures, when the number of the drain holes is one, the diameter of the drain hole is within the range of 0.5 mm to 20 mm. In this way, the water amount of the rice soup sprayed from the multiple drain holes can be further increased, the height of the water column formed is higher and more uniform, which is beneficial to improve the effect of the rice soup on washing the starch in the rice. The diameter of the drain hole is preferably 5 mm, 10 mm or 20 mm. Alternatively, the diameter of the overflow hole is within the range of 0.5 mm to 10 mm. In this way, the above-mentioned overflow hole with a diameter within the range of 0.5 mm to 10 mm facilitates the starch to flow back to the container of the cooking utensil along with the rice soup from the overflow hole 111.

[0044] As shown in Figure 1 and Figure 2 , the overflow hole 111 is multiple, and the multiple overflow holes 111 are uniformly distributed on the bottom wall 11 of the steamer. In this way, after the starch in the rice is washed away, the starch flows back to the container of the cooking utensil along with the rice soup from the multiple overflow holes uniformly, which improves the washing effect of the rice soup on the rice grains. The above-mentioned multiple overflow holes 111 uniformly distributed on the bottom wall 11 of the steamer means that the multiple overflow holes 111 form multiple circles along the radial direction of the bottom wall 11 of the steamer, and the distance between each adjacent two circles is equal.

[0045] As shown in Figure 1 and Figure 2As shown, the inventor found that when the height of the protruding structure 20 is too low, the amount of rice contained in the steamer is too small, and when the height of the protruding structure 20 is too high, the rising path of the rice soup from the drainage space 21 is prolonged, the water pressure of the water column formed is too small, and the effect of the rice soup in washing the starch in the rice is poor. Therefore, the ratio between the height of the protruding structure 20 and the height of the side wall 12 of the steamer is in the range of 2 / 5-4 / 5. In this way, on the one hand, the amount of rice contained in the steamer is appropriate, and on the other hand, it is ensured that the area covered by the water column formed by the spray can completely cover the circumferential area of the bottom wall of the steamer. The ratio between the height of the protruding structure 20 and the height of the side wall of the steamer is preferably 3 / 5.

[0046] As shown in Figure 1 and Figure 2 When the material of the steamer is plastic, the protruding structure 20 is processed for easy demolding, and the protruding structure 20 gradually shrinks from bottom to top.

[0047] As shown in Figure 1 and Figure 2 The protruding top wall 24 is a flat plate structure. The flat plate structure of the protruding top wall 24 allows the boiling rice soup to orderly gather at the drain hole 22 before entering the drain hole 22, which is beneficial to improve the water pressure of the boiling rice soup.

[0048] Of course, in other embodiments not shown in the other figures, the protruding top wall is an arc-shaped plate structure.

[0049] As shown in Figure 1 and Figure 2 In order to facilitate processing and simple molding, the protruding structure 20 and the bottom wall 11 of the steamer are integrally formed. Of course, in other embodiments not shown in the other figures, the protruding structure and the bottom wall of the steamer are fixedly connected. Specifically, the protruding structure is fixedly connected with the bottom wall of the steamer by adhesion or welding or riveting.

[0050] Of course, in other embodiments not shown in the other figures, in order to facilitate the connection between the protruding structure and the bottom wall of the steamer, the protruding structure and the bottom wall of the steamer are detachably connected. Specifically, the notch is provided with an internal thread, and the protruding side wall is provided with an external thread matched with the internal thread.

[0051] As shown in Figure 1 and Figure 2 In order to facilitate the taking and placing of the steamer into the container of the cooking appliance, the steamer further comprises a flange 13 arranged at the top of the side wall 12 of the steamer. In this way, the flange 13 can be lapped and matched with the container of the cooking appliance, so that the steamer is suspended and arranged.

[0052] As shown in Figure 1 and Figure 2As shown, the steamer side wall 12 is a closed structure. In this way, the boiling rice soup cannot enter the steamer from the steamer side wall 12, so that the boiling rice soup can be accumulated into the drainage space 21, which is conducive to improving the water pressure of the boiling rice soup.

[0053] It should be noted that the steamer side wall 12 being a closed structure can be understood as that the steamer side wall 12 has no holes communicating the inside and outside of the steamer side wall 12, that is, the rice soup and other fluids cannot pass through the steamer side wall 12.

[0054] The application also provides a cooking appliance, such as Figures 3 to 5 As shown, the cooking appliance comprises a container 30 and a steamer 40. The steamer 40 is removably arranged in the container 30, and the steamer bottom wall 11 of the steamer has a spacing with the bottom wall of the container 30, and the steamer is the above-mentioned steamer. Since the steamer of the application can solve the problem of poor starch dissolving effect of the rice cooking device in the related art, the cooking appliance comprising the steamer has the same effect. The above-mentioned spacing allows a water storage space to be left between the steamer bottom wall 11 and the bottom wall of the container 30, so that the rice and the rice soup can be separated after the rice in the steamer is half-cooked or cooked.

[0055] The application also provides a cooking appliance, such as Figures 3 to 5 As shown, the cooking appliance comprises a container 30 and a steamer 40. The steamer is the above-mentioned steamer, and the steamer is removably arranged in the container 30. Since the above-mentioned steamer can solve the problem of poor starch dissolving effect of the rice cooking device in the related art, the cooking appliance comprising the steamer has the same effect. The flange 13 of the steamer 40 is supported by the container 30, and the flange 13 and the supporting surface of the container 30 are in sealing cooperation. Since the flange 13 and the supporting surface of the container 30 are in sealing cooperation, the rice soup cannot flow between the flange 13 and the container 30, and the rice soup can only enter the steamer 40 through the drainage space 21 of the steamer 40, thereby ensuring that there is sufficient rice soup to better wash the starch in the rice.

[0056] As shown in FIG. 1, Figures 3 to 5 As shown, the inner wall of the container 30 is provided with a supporting protrusion 31, and the supporting protrusion 31 is annular and extends along the circumference of the container 30. When the steamer 40 is placed in the container 30, the flange 13 of the steamer 40 is in sealing cooperation with the supporting protrusion 31. On the one hand, the supporting protrusion 31 supports the flange 13 of the steamer 40, so that the steamer 40 is suspended in the container 30; on the other hand, the above-mentioned supporting surface is the bearing contact surface of the supporting protrusion 31, which seals the gap between the flange 13 and the supporting protrusion 31. Of course, in other embodiments not shown in the figures, the supporting protrusions are a plurality of supporting protrusions, and the plurality of supporting protrusions are arranged at intervals along the circumference of the container.

[0057] As shown in FIG. 1, Figure 3 and Figure 5As shown, the cooking utensil further comprises a housing located outside the container 30 and a heating device located between the container 30 and the housing, and the heating device is capable of heating the container 30.

[0058] In the embodiment, the cooking utensil is an electric pressure cooker. The container 30 is preferably an inner pot. Of course, in the embodiment not shown in the figure, the cooking utensil can also be an electric rice cooker, a low-pressure rice cooker, a soybean milk machine, a food processor, an electric stew pot, a frying machine, a multifunctional pot, etc.
