Description

Technical Field

[0001] This invention relates to the field of small household appliance technology, and more specifically, to a steamer and a cooking appliance having the same. Background Technology

[0002] When the rice cooker is cooking, first put the washed rice into the cooker, then add water to the pot. Usually, the water level should be about 20mm above the rice level. This will prevent the rice from burning and ensure that it is cooked through.

[0003] The rice cooking device in the relevant technology soaks rice in water for cooking. Because the water and rice are in constant contact, the cooked rice contains a large amount of starch. After being absorbed by the human body, it is quickly converted into sugar, which cannot meet the needs of people with diabetes, high blood lipids and high blood pressure for low-sugar staple food.

[0004] To address the aforementioned problems, a rice cooking device has been provided in the related technology. This device includes a pot and a steamer located inside the pot. Rice is placed in the steamer, and water is added to the pot until the rice in the steamer is submerged. During the heating process, the rice absorbs water and becomes semi-cooked rice, while the water becomes rice water. When the level of the rice water is lower than the steamer and it boils, the boiling rice water can enter the steamer through the gap between the side wall of the steamer and the side wall of the pot, as well as through the flow holes in the side wall of the steamer, to continue heating the rice. As the boiling rice water rises along the side wall of the steamer, the water pressure gradually decreases. The boiling rice water can only flow 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 does not come into contact with the rice water. This results in poor starch dissolution, leading to a high sugar content in the cooked rice, which cannot meet the needs of people who consume low-sugar staple foods. Summary of the Invention

[0005] The main objective of this invention is to provide a steamer and a cooking appliance having the same, in order to solve the problem that rice cooking devices in the related art have poor starch dissolution effect.

[0006] To achieve the above objectives, according to one aspect of the present invention, a steamer is provided, comprising: a bottom wall of the steamer, wherein a flow hole is provided on the bottom wall of the steamer; a side wall of the steamer connected to the bottom wall of the steamer; and a protruding structure, which is provided upwardly at a notch in the bottom wall of the steamer and located inside the side wall of the steamer, the protruding structure including a protruding side wall and a protruding top wall, wherein a drainage space is formed between the protruding top wall and the protruding side wall, and a plurality of first drainage holes communicating with the drainage space are provided on the protruding side wall; wherein the steamer is made of plastic or metal.

[0007] Using the technical solution of this invention, when using the steamer, rice is placed inside, and water is added to the container of the cooking appliance. During the heating process, the rice absorbs water and becomes semi-cooked rice, while the water becomes rice water. When the level of the rice water is lower than the lowest point of the steamer, the rice water continues to boil. Because the drainage space can form a narrow space, the boiling rice water is squeezed into the drainage space and directly enters the steamer through the multiple first drainage holes of the raised structure. Compared with the related technology where the boiling rice water rises along the side wall of the steamer, which easily leads to a gradual decrease in water pressure, in the technical solution of this application, the water pressure of the boiling rice water does not decrease significantly. This allows the rice water entering the steamer to form a water column. As the water column falls, it can cover almost all the rice in the steamer and continuously wash the rice grains, fully dissolving the starch in the rice and improving the starch dissolution effect. Because multiple first drain holes are located on the raised sidewall, rice water can be rinsed from multiple directions within the steamer, ensuring even rinsing of the rice. After the starch in the rice is rinsed away, it flows back into the cooking vessel through the drain holes along with the rice water. This repeated rinsing of the rice results in a lower sugar content in the cooked rice, meeting the needs of individuals consuming low-sugar staple foods. Therefore, the technical solution of this application effectively solves the problem of poor starch dissolution in related technologies.

[0008] Furthermore, a second drain hole communicating with the drainage space is provided on the raised top wall. In the above structure, due to the provision of the second drain hole, when boiling rice water is squeezed into the drainage space, it can enter the steamer not only directly from the first drain hole but also directly from the second drain hole. This allows water jets to be formed simultaneously from both the first and second drain holes, ensuring that the water jets sprayed into the steamer better cover all the rice inside. As the rice water continuously washes the rice grains, the effect of washing away the starch in the rice is more even.

[0009] Furthermore, the axis of the first drain hole is parallel to the bottom wall of the steamer or the angle between the axis and the bottom wall of the steamer is less than or equal to 70°; and / or, the angle between the axis of the second drain hole and the bottom wall of the steamer is in the range of 70° to 90°. In the above structure, when the boiling rice water is sprayed out from a direction parallel to the bottom wall of the steamer or from any angle greater than 0° and less than 90° to form a water column, the rice water can be sprayed to a higher position. In this way, when the rice water falls, it covers a larger area of ​​the rice in the steamer, which can better wash away the starch in the rice.

[0010] Furthermore, there are multiple first drainage holes, forming multiple hole groups. Within each hole group, the multiple first drainage holes are arranged vertically along the raised sidewall. The ratio of the distance between two adjacent hole groups to the diameter of the first drainage hole is between 1.5 and 5. In this structure, sufficient rice water can be sprayed from the multiple first drainage holes, making the rice water more effective at rinsing the starch in the rice, and simultaneously ensuring more uniform heating of the rice.

[0011] Furthermore, the diameter of the second drain hole is in the range of 0.5 mm to 10 mm, and / or the diameter of the first drain hole is in the range of 0.5 mm to 3 mm. This structure allows people consuming low-sugar staple foods to obtain well-cooked and palatable rice.

[0012] Furthermore, in order for the cooking appliance to produce cooked rice with a good texture, the ratio of the diameter of the second drain hole to the diameter of the first drain hole is in the range of 3 / 1 to 1 / 1.

[0013] Furthermore, when the material of the steamer is plastic, a raised structure is processed to facilitate demolding. The raised structure gradually tapers and extends from bottom to top.

[0014] Furthermore, the raised top wall is a flat plate structure or an arc-shaped plate structure. The raised top wall of the above structure allows the boiling rice water to collect orderly at the second drain hole before entering it, which helps to increase the water pressure of the boiling rice water.

[0015] Furthermore, the ratio between the height of the raised structure and the height of the steamer sidewall is in the range of 2 / 5 to 4 / 5. This structure ensures that the amount of rice placed in the steamer is appropriate, and also guarantees that the area covered by the water jet spray can completely cover the circumferential area of ​​the bottom wall of the steamer.

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

[0017] Furthermore, for ease of processing and simple molding, the raised structure is fixedly connected to the bottom wall of the steamer or is an integrally molded structure.

[0018] Furthermore, to facilitate placing the steamer into the container of the cooking utensil, the steamer also includes a flange on the top of the side wall of the steamer.

[0019] Furthermore, the side walls of the steamer are enclosed. In this structure, boiling rice water cannot enter the steamer from the side walls, allowing it to collect in the drainage space, which helps to increase the water pressure of the boiling rice water.

[0020] According to another aspect of the present invention, a cooking utensil is provided, comprising: a container; and a steamer removably disposed within the container, wherein a gap exists between the bottom wall of the steamer and the bottom wall of the container, and the steamer is the aforementioned steamer. Since the aforementioned steamer can solve the problem of poor starch dissolution in related art rice cooking devices, the cooking utensil including this steamer has the same effect.

[0021] According to another aspect of the present invention, a cooking utensil is provided, comprising: a container; and a steamer, the steamer being the aforementioned steamer, the steamer being removably disposed within the container, the flange of the steamer being supported by the container, and the flange and the supporting surface of the container being sealed together. Due to the sealed fit between the flange and the supporting surface of the container, rice water cannot flow between the flange and the container; instead, the rice water can only enter the steamer through the drainage space of the steamer, thereby ensuring sufficient rice water to better rinse the starch in the rice.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[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 protruding structure 20. The bottom wall 11 has overflow holes 111. The side wall 12 is connected to the bottom wall 11. The protruding structure 20 protrudes upward from the notch 112 in the bottom wall 11 and is located inside the side wall 12. The protruding structure 20 includes a protruding side wall 25 and a protruding top wall 24, forming a drainage space 21 between the top wall 24 and the side wall 25. The protruding side wall 25 has a plurality of first drainage holes 23 communicating with the drainage space 21. The steamer is made of plastic or metal.

[0034] Applying the technical solution of this embodiment, when using the steamer, rice is placed inside, and water is added to the container of the cooking appliance. During the heating process of the cooking appliance, the rice absorbs water and becomes semi-cooked rice, while the water becomes rice water. When the level of the rice water is lower than the lowest point of the steamer, the rice water continues to boil. Because the drainage space 21 can form a narrow space, the boiling rice water is squeezed into the drainage space 21 and directly enters the steamer through the multiple first drainage holes 23 of the protruding structure 20. Compared with the related technology where the boiling rice water rises along the side wall of the steamer and the water pressure gradually decreases, in the technical solution of this embodiment, the water pressure of the boiling rice water does not decrease significantly, allowing the rice water entering the steamer to form a water column. This water column can cover almost all the rice in the steamer during its descent and continuously wash the rice grains, fully dissolving the starch in the rice and improving the starch dissolution effect. Because multiple first drain holes 23 are provided on the raised sidewall 25, rice water can be rinsed from multiple directions by the raised sidewall 25 onto the rice in the steamer, ensuring that the rice water can evenly rinse the rice. After the starch in the rice is rinsed away, the starch flows back into the container of the cooking appliance through the overflow hole 111 along with the rice water. In this way, after repeatedly rinsing the starch in the rice, the cooked rice has a lower sugar content, which can meet the needs of people who consume low-sugar staple foods. Therefore, the technical solution of this embodiment effectively solves the problem of poor starch dissolution effect in rice cooking devices in related technologies.

[0035] It should be noted that when using the steamer, put the rice into the steamer and add water to the container of the cooking utensil. The water level does not necessarily have to submerge the rice in the steamer. The water level can be submerged, partially submerged, or the water level can be below the steamer.

[0036] Furthermore, in this embodiment, when the steamer is taken out of the container of the cooking appliance, the protruding structure 20 can form a grip, which makes it easy to operate and convenient to take out and put away the steamer.

[0037] For ease of processing and molding, the steamer in this embodiment is made of plastic. Of course, in other embodiments not shown in the figures, the steamer is made of metal. The plastic is preferably PP (polypropylene). The metal is preferably stainless steel or aluminum.

[0038] like Figure 1 and Figure 2As shown, a second drain hole 22 communicating with the drainage space 21 is provided on the raised top wall 24. Because of the second drain hole 22, when boiling rice water is squeezed into the drainage space 21, it can enter the steamer directly not only through the first drain hole 23 but also through the second drain hole 22. This allows water jets to be formed simultaneously from both the first and second drain holes 23, ensuring that the water jets sprayed into the steamer better cover all the rice inside. As the rice water continuously washes the rice grains, the effect of washing away the starch in the rice is more even.

[0039] like Figure 2 As shown, the axis of the first drain hole 23 is parallel to the bottom wall 11 of the steamer. This allows the boiling rice water to spray from the first drain hole 23, forming a water column that reaches a higher position. This results in a larger area of ​​the rice covered when the rice water falls, effectively rinsing away the starch. The angle between the axis of the second drain hole 22 and the bottom wall 11 of the steamer is between 70° and 90°. This allows the boiling rice water to spray from any angle within this range, also reaching a higher position and further rinsing away the starch. Furthermore, when the boiling rice water is simultaneously sprayed from the first drain hole 23 and from multiple angles within the 70° to 90° range, it ensures that the rice water covers all the rice in the steamer without any blind spots. This larger drop in water water improves the rinsing effect on the starch and also ensures more even heating of the rice. The angle between the axis of the second drain hole and the bottom wall 11 of the steamer is preferably 75°, 80° or 90°.

[0040] Of course, in embodiments not shown in the figures, the angle between the axis of the first drain hole and the bottom wall of the steamer is less than or equal to 70°. This allows the boiling rice water to spray out at any angle within the range of 70° to form a water column, resulting in a higher spray height. Consequently, the rice water covers a larger area of ​​the rice inside the steamer when it falls, effectively rinsing away the starch. The angle between the axis of the first drain hole 23 and the bottom wall 11 of the steamer is preferably 20°, 45°, 60°, or 70°. Alternatively, the angle between the axis of the second drain hole and the bottom wall of the steamer may be in the range of 70° to 90°.

[0041] like Figure 1 and Figure 2As shown, there are multiple first drain holes 23, forming multiple hole groups. The multiple first drain holes 23 in each hole group are arranged vertically along the raised sidewall 25. The ratio of the spacing between two adjacent hole groups to the diameter of the first drain hole 23 is between 1.5 and 5. This allows sufficient rice water to be sprayed from the multiple first drain holes 23, making the rice water more effective at rinsing the starch in the rice and simultaneously ensuring more even heating of the rice. The ratio of the spacing between two adjacent hole groups to the diameter of the first drain hole 23 is preferably 2 or 3.

[0042] like Figure 2 As shown, when both the number of second drain holes 22 and the number of first drain holes 23 are multiple, in order to produce cooked rice with a good texture, the inventors tested the cooked rice and found that: when the diameters of the second drain holes 22 and the first drain holes 23 are within the range of greater than 0.1 mm and less than 0.5 mm, the top layer of the cooked rice is dry, the overall texture is hard, and there is a slight undercooking; when the diameters of the second drain holes 22 and the first drain holes 23 are within the range of 0.5 mm to 3 mm, the top layer of the cooked rice is slightly dry, and the overall texture is relatively hard; when the diameter of the second drain holes 22 is within the range of 3.5 mm to 6 mm, the overall texture of the cooked rice is soft and sticky, with a moderate taste; when the diameter of the second drain holes 22 is within the range of 6.5 mm to 10 mm, the overall texture of the cooked rice is relatively soft; when the diameter of the second drain holes 22 is greater than 10 mm, the top layer of the cooked rice is too mushy, the overall texture is soft and mushy, and the taste is poor. Therefore, the above tests show that the diameter of the second drain hole 22 in this application is in the range of 0.5mm to 10mm, and the diameter of the first drain hole 23 is in the range of 0.5mm to 3mm. This allows people consuming low-sugar staple foods to obtain cooked rice with a good texture. Furthermore, when the diameter of the first drain hole 23 is smaller than the diameter of the second drain hole 22, less water enters the steamer through the first drain hole 23, while more water enters the steamer through the second drain hole 22, resulting in a wider water column covering the rice in the steamer. Preferably, the diameter of the second drain hole 22 is 2mm, 4mm, 6mm, or 8mm, and the diameter of the first drain hole 23 is 2mm.

[0043] Of course, in other embodiments not shown in the figures, the diameter of the second drain hole is in the range of 0.5 mm to 10 mm, or the diameter of the first drain hole is in the range of 0.5 mm to 3 mm.

[0044] Of course, in embodiments not shown in other figures, there may be only one second drain hole.

[0045] like Figure 2As shown, in order for the cooking appliance to produce cooked rice with a better texture, the ratio of the diameter of the second drain hole 22 to the diameter of the first drain hole 23 is in the range of 3 / 1 to 1 / 1.

[0046] like Figure 1 and Figure 2 As shown, when the material of the steamer is plastic, a raised structure 20 is processed to facilitate demolding. The raised structure 20 extends from bottom to top in a gradually tapering manner.

[0047] like Figure 1 and Figure 2 As shown, the raised top wall 24 has a flat plate structure. The raised top wall 24 of the flat plate structure allows the boiling rice water to gather orderly at the second drain hole 22 before entering the second drain hole 22, which helps to increase the water pressure of the boiling rice water.

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

[0049] like Figure 1 and Figure 2 As shown, the inventors discovered that when the height of the protruding structure 20 is too low, the amount of rice that can be placed in the steamer is too small; when the height of the protruding structure 20 is too high, the rising channel of the rice water from the drainage space 21 is prolonged, resulting in insufficient water pressure in the formed water column and poor washing effect of the rice water on the starch in the rice. Therefore, the ratio between the height of the protruding structure 20 and the height of the side wall of the steamer in this application is in the range of 2 / 5 to 4 / 5. This ensures that the amount of rice that can be placed in the steamer is appropriate, and also ensures that the area covered by the formed water column spray can completely cover the circumferential area of ​​the bottom wall of the steamer. The preferred ratio between the height of the protruding structure 20 and the height of the side wall of the steamer is 3 / 5.

[0050] like Figure 1 and Figure 2 As shown, for ease of processing and simple molding, the raised structure 20 and the bottom wall 11 of the steamer are integrally molded.

[0051] Of course, in embodiments not shown in the figures, the protruding structure is fixedly connected to the bottom wall of the steamer. Specifically, the protruding structure is fixedly connected to the bottom wall of the steamer by adhesive bonding, welding, or riveting.

[0052] Of course, in other embodiments not shown in the figures, the protruding structure is detachably connected to the bottom wall of the steamer to facilitate connection between the protruding structure and the bottom wall of the steamer. Specifically, the notch is provided with an internal thread, and the side wall of the protrusion is provided with an external thread that mates with the internal thread.

[0053] like Figure 1 and Figure 2As shown, to facilitate placing the steamer into the container of the cooking utensil, the steamer also includes a flange 13 located on the top of the side wall 12 of the steamer. In this way, the flange 13 can overlap and cooperate with the container of the cooking utensil, so that the steamer is suspended in the air.

[0054] like Figure 1 and Figure 2 As shown, the side wall 12 of the steamer is a closed structure. In this way, the boiling rice water cannot enter the steamer from the side wall 12, allowing the boiling rice water to collect in the drainage space 21, which helps to increase the water pressure of the boiling rice water.

[0055] It should be noted that the side wall 12 of the steamer is a closed structure, which can be understood as the absence of holes on the side wall 12 that connect the inner and outer sides of the side wall 12, meaning that fluids such as rice soup cannot pass through the side wall 12 of the steamer.

[0056] This application also provides a cooking utensil, such as Figures 3 to 5 As shown, the cooking appliance includes a container 30 and a steamer 40. The steamer 40 is removably disposed inside the container 30, and there is a gap between the bottom wall 11 of the steamer and the bottom wall of the container 30. The steamer is the aforementioned type. Since the steamer of this application can solve the problem of poor starch dissolution in related technologies, cooking appliances including this steamer have the same effect. The aforementioned gap allows for water storage space between the bottom wall 11 of the steamer and the bottom wall of the container 30, enabling the separation of rice and rice water after the rice is partially or fully cooked in the steamer.

[0057] This application also provides a cooking utensil, such as Figures 3 to 5 As shown, the cooking appliance includes a container 30 and a steamer 40. The steamer is the one described above, and it is removably installed inside the container 30. Since the steamer described above solves the problem of poor starch dissolution in rice cooking devices of the related art, the cooking appliance including this 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 sealed together. Due to the sealed fit between the flange 13 and the supporting surface of the container 30, rice water cannot flow between the flange 13 and the container 30; the rice water can only enter the steamer 40 through the drainage space 21, thereby ensuring that there is sufficient rice water to better rinse the starch in the rice.

[0058] like Figures 3 to 5As shown, a support protrusion 31 is provided on the inner wall of the container 30. The support protrusion 31 is annular and extends circumferentially along the container 30. When the steamer 40 is placed inside the container 30, the flange 13 of the steamer 40 seals against the support protrusion 31. On the one hand, the support protrusion 31 supports the flange 13 of the steamer 40, allowing the steamer 40 to suspend inside the container 30. On the other hand, the aforementioned support surface serves as the bearing contact surface of the support protrusion 31, sealing the gap between the flange 13 and the support protrusion 31. Of course, in other embodiments not shown in the figures, there are multiple support protrusions, which are arranged at intervals along the circumference of the container.

[0059] like Figure 3 and Figure 5 As shown, the cooking appliance also includes a shell located outside the container 30 and a heating device located between the container 30 and the shell, the heating device being able to heat the container 30.

[0060] In this embodiment, the cooking appliance is an electric pressure cooker. The container 30 is preferably an inner pot. Of course, in embodiments not shown in the figures, the cooking appliance can also be a rice cooker, a low-pressure rice cooker, a soy milk maker, a food processor, an electric slow cooker, a stir-fry machine, a multi-functional cooker, etc.

[0061] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0062] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0063] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention.
