Description

Technical Field

[0001] The utility model relates to the field of household cooking electrical appliance design, in particular to an easy-to-clean cooking liner. Background Art

[0002] At present, the inner pot of cooking utensils such as rice cookers is generally made of metal. In order to make it easier to clean, a non-stick coating is applied to the inner wall of the inner pot. However, the non-stick coating is prone to fall off after long-term use. In addition, there are many kinds of non-stick coating materials, some of which may affect the health of users. Therefore, many users are skeptical about the use of coatings.

[0003] Therefore, the prior art needs to be improved. Utility Model Content

[0004] In view of this, the utility model provides an easy-to-clean cooking pot, which is used to solve the problem in the prior art that the non-stick coating in the cooking pot falls off after long-term use.

[0005] To achieve one or part or all of the above purposes or other purposes, the utility model provides an easy-to-clean cooking pot, wherein the inner surface of the easy-to-clean cooking pot has a plurality of grooves in an array, each of the grooves is horizontally arranged on the inner surface of the easy-to-clean cooking pot and connected end to end.

[0006] Preferably, the easy-to-clean cooking pot includes a bottom wall, a side wall and a flange wall from bottom to top, the bottom wall and the side wall have an arc transition, and the side wall and the flange wall have an arc transition; the grooves are only distributed on the bottom wall and / or the side wall, so as to ensure the sealing effect of the flange wall.

[0007] Preferably, the groove width a is 0.1 mm to 1 mm. The groove depth is 0.1 mm to 0.5 mm. The groove width and groove depth are set within this range, so that the groove has a better water absorption effect while ensuring the strength of the inner liner structure, thereby ensuring the non-stick property and ensuring that the groove is easy to process.

[0008] Preferably, the spacing b between any two adjacent grooves is 0.1 mm-1 mm. By setting the spacing between the grooves to less than 1 mm, it can be ensured that the position between the two grooves also has good non-stick properties, while the spacing between the grooves is set to more than 0.1 mm, reducing the difficulty of processing.

[0009] Preferably, the groove width a is 0.5 mm, and the groove depth is 0.3 mm. The depth and width are designed to optimize the water absorption capacity of the groove.

[0010] Preferably, the groove is a corrugated groove. This ensures that there is no long distance of non-grooved area at the same level, so that rice grains or other food materials can be fully soaked, thereby ensuring a non-stick effect. In addition, the use of a broken line or curved groove can greatly reduce the problem of rigidity reduction caused by grooving, which helps to maintain the rigidity of the inner pot.

[0011] Preferably, the distance between any two adjacent wave crests on the groove is D, 2.5a≤D≤5a; the height from the wave crest to the wave trough on the groove is H, 2.5a≤H≤8a. With such a proportional design, the water absorption of the groove can ensure that the rice grains or other food in the inner pot are fully soaked, achieving a better non-stick effect.

[0012] Preferably, the distance D between any two adjacent wave crests on the groove is 3a, and the height H from the wave crest to the wave trough on the groove is 3.5a. Under this ratio design, the non-stick effect is optimal.

[0013] Preferably, the groove is sawtooth-shaped.

[0014] Preferably, the groove is in a sine wave shape. The lines of the sine wave groove are relatively soft and are not easily worn during cleaning compared to the sawtooth wave groove.

[0015] Implementing the embodiments of the present utility model will have the following beneficial effects:

[0016] 1. The circular groove is used to absorb and store water to achieve the non-stick effect, so that the cooking pot can have the non-stick effect without the use of non-stick coating, solving the problem of non-stick coating detaching after long-term use in the prior art;

[0017] 2. In the preferred embodiment, the groove is a corrugated groove. With this design, water is preferentially stored at each trough position of the groove. Compared with ordinary linear grooves, during the cooking process, the water content gradually decreases, and the water can be evenly dispersed in the corrugated groove to ensure the all-round non-stick effect of the inner wall of the inner pot. In addition, the design of the corrugated groove prevents continuous long grooves from appearing at the same horizontal position, further preventing rice grains from getting stuck in the groove.

[0018] 3. In a further preferred embodiment, by designing the ratio of the single wave length, i.e., the distance between adjacent wave crests and the groove width, and the ratio of the wave height to the groove width, it can be effectively ensured that the water in the wave groove can be dispersed from the wave crest to the troughs on both sides of the wave crest.

[0031] Reference Figure 1 to Figure 2 An embodiment of the utility model provides an easy-to-clean cooking pot, the inner surface of which is arrayed with a plurality of circles of grooves 1, and the grooves 1 are horizontally arranged on the inner surface of the easy-to-clean cooking pot.

[0032] In some optional embodiments, such as Figure 1 As shown, the easy-to-clean cooking pot includes a bottom wall 10, a side wall 20 and a flange wall 30 from bottom to top, and the bottom wall 10 and the side wall 20 have an arc transition, and the side wall 20 and the flange wall 30 have an arc transition; the grooves 1 are only distributed on the bottom wall 10 and / or the side wall 20. In some embodiments, the grooves 1 are only distributed on the bottom wall 10 and the side wall 20, which can ensure that the maximum area in the pot achieves a non-stick effect.

[0033] In some optional embodiments, the width of the groove 1 is a, the size of a is 0.1mm~1mm, the depth of the groove 1 is 0.1mm~0.5mm, and the spacing between any two grooves 1 is 0.1mm-1mm. With the above depth, width and spacing, without using a non-stick coating, it has the best water absorption effect and achieves the best non-stick effect. At the same time, a depth of more than 0.1mm combined with a depth of more than 0.1mm can ensure the water storage effect while ensuring that foreign matter in the groove 1 can be easily cleaned out during cleaning. Specifically, the width of the groove 1 can take any value within the above range, such as 0.1mm, 0.3mm, 0.5mm, 1mm; the depth of the groove 1 can take any value within the above range, such as 0.1mm, 0.3mm, 0.5mm; the best is that the width of the groove 1 is 0.5mm and the depth of the groove 1 is 0.3mm. If the depth and width of groove 1 are too large, rice grains may get stuck in groove 1 easily. If the depth of groove 1 is too large and the width is too small, it may be difficult to clean foreign matter in groove 1. The depth and width design can optimize the water absorption capacity of groove 1 and prevent rice grains from getting stuck in groove 1. At the same time, the cleanability of the inner pot is ensured.

[0034] In an alternative embodiment, if Figure 2 As shown, the groove 1 is sawtooth-shaped. By adopting the broken line groove 1, there will be no long distance of non-grooved parts at the same horizontal position, which can make the rice grains or other ingredients fully soaked, thereby ensuring the non-stick effect; and in the cooking process, the water content gradually decreases, and the water will be preferentially retained in the trough position of the groove 1. The water can present a uniformly dispersed water storage effect in the wave-shaped groove 1, thereby ensuring a full range of non-stick effects; in addition, it can also greatly reduce the problem of rigidity weakening caused by the design of the groove 1, which helps to maintain the rigidity of the inner pot. More specifically, the distance between any two adjacent peaks on the groove 1 is D, 2.5a≤D≤5a; the height from the peak to the trough on the groove 1 is H, 2.5a≤H≤8a. With such a proportional design, the water absorption of the groove 1 can ensure the full soaking of the rice grains or other ingredients in the inner pot, achieving a better non-stick effect.

[0035] As a preferred embodiment, the distance D between any two adjacent wave crests on the groove 1 is 3a, and the height H from the wave crest to the wave trough on the groove 1 is 3.5a. Under this ratio design, the non-stick effect is optimal.

[0036] In another alternative embodiment, if Figure 3As shown, the groove 1 is in a sine wave shape. Similar to the sawtooth wave groove, the sinusoidal wave groove 1 with a curved shape can achieve sufficient infiltration of the rice grains. In addition, it can greatly reduce the problem of weakening rigidity caused by the grooves, which helps to maintain the rigidity of the inner pot. At the same time, the sinusoidal wave groove 1 is not easily worn during cleaning because the lines are relatively flat compared to the sawtooth wave groove 1.

[0037] In yet another alternative embodiment, Figure 4 As shown, the groove 1 is in a straight line on the inner surface of the easy-to-clean cooking pot. Compared with the embodiment of the corrugated groove, in the late stage of cooking, the water in the groove 1 gradually flows out, and the water in the groove 1 will be mutually adsorbed, so that there is less water in some places in the groove 1, and the uniformity of the water film is relatively poor. However, this embodiment adopts a straight groove 1, which has a simple structure, is easy to process, and is easier to clean.

[0038] Of course, in some other optional embodiments, the inner wall of the liner can also adopt grooves 1 of various structures, for example, sawtooth grooves or sinusoidal grooves are adopted on the side wall 20 of the liner, and standard annular grooves are adopted on the bottom wall 10. By taking advantage of the different positions of the bottom wall 10 and the side wall 20, grooves 1 of different structures are adopted, and the advantages of two or more groove 1 structures are fully utilized.

[0039] The easy-to-clean cooking pot provided by the embodiment of the utility model has the following beneficial effects:

[0040] 1. The circular groove 1 is used to achieve the non-stick effect, so that the cooking pot can have the non-stick effect without the use of a non-stick coating, solving the problem of the non-stick coating in the prior art being detached after long-term use;

[0041] 2. In some preferred embodiments, the groove 1 is a corrugated groove. With this design, water is preferentially stored at each trough position of the groove 1. Compared with the ordinary straight groove 1, water can be evenly dispersed in the corrugated groove 1 to ensure the all-round non-stick effect of the inner wall of the inner pot. In addition, the design of the corrugated groove prevents continuous long grooves 1 from appearing at the same horizontal position, further preventing rice grains from being easily stuck in the groove 1.

[0042] 3. In some embodiments, the water storage capacity of the corrugated trough can be effectively guaranteed and the uniformity of water storage can be improved by designing the ratio of the single wave length, i.e., the distance between adjacent wave peaks and the trough width, and the ratio of the wave height and the trough width.

[0043] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
