[0002] Steamers, steam ovens, and other cooking containers heat food with high-temperature steam, which not only improves the taste of the food but also makes it easy to use. During the cooking process, some of the high-temperature steam in these containers condenses to form condensed water, which flows back to the bottom of the container.

[0003] To recover and remove condensed water, existing all-in-one steamers feature a sink in the center of the bottom of the cooking pot. Metal heating pipes are installed on the outside of the bottom of the pot to heat the condensed water collected in the sink. Cooking pots are typically made of enameled material. When steaming food in a container, the container comes into contact with the sink, preventing the condensed water from flowing into the sink. The heating pipes continue to operate, causing the sink to overheat, leading to problems such as enameling and cracking, shortening the lifespan of the cooking pot. Utility Model Content

[0004] The first purpose of the present invention is to provide a cooking liner, which can solve the problems that the sink at the bottom of the existing cooking liner contacts the container, hindering the condensed water from flowing into the sink, and the heating tube cannot heat the condensed water normally, causing the sink to burst due to high temperature.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] First, a cooking liner is provided, which includes a bottom wall, and the bottom wall includes a sinking area, multiple support areas and multiple guide areas. The multiple support areas and the multiple guide areas are staggered around the sinking area. The height of the upper surface of the support area at the same horizontal distance from the center of the sinking area is higher than the height of the upper surface of the guide area. The height of the upper surface of the guide area is higher than the sinking area. The height of the upper surface of the guide area gradually increases from the center of the sinking area to the outside.

[0007] As an optional structure of the present invention, part of the bottom wall surrounding the sinking area has a plurality of grooves that are concave downward, and the plurality of grooves are arranged at intervals to form a plurality of the guide areas, and the bottom wall between adjacent guide areas forms the support area.

[0008] As an optional structure of the present invention, the width of the upper opening of the groove gradually increases outward from the center of the sinking area.

[0009] As an optional structure of the present invention, the depth of the groove gradually increases outward from the center of the sinking area.

[0010] As an optional structure of the present invention, the height of the upper surface of the support area gradually increases outward from the center of the sinking area.

[0011] As an optional structure of the present invention, part of the bottom wall surrounding the sinking area has a plurality of ribs protruding upward, and the plurality of ribs are arranged at intervals to form a plurality of the support areas, and the bottom wall between adjacent support areas forms the guide area.

[0012] As an optional structure of the present invention, the width of the bottom of the convex rib gradually decreases outward from the center of the sinking area.

[0013] As an optional structure of the present invention, the thickness of the convex rib from the bottom to the top gradually decreases outward along the center of the sinking area.

[0014] As an optional structure of the present invention, the height of the upper surface of the support area formed by the convex rib is flush outward along the center of the sinking area.

[0015] The second object of the present invention is to provide a cooking appliance having the above-mentioned cooking liner which can solve the problems of existing all-in-one machines such as the utensil contacting the sink at the bottom of the cooking liner, thereby preventing condensed water from flowing into the sink, and the heating tube being unable to heat the condensed water normally, causing the sink to explode due to high temperature.

[0016] To achieve this purpose, the present invention adopts the following technical solutions on the other hand:

[0017] Next, a cooking appliance is provided, comprising the above-mentioned cooking liner, the cooking appliance further comprising a heating element, the heating element being arranged on the outside of the cooking liner, the heating element being used to heat cooking water in the sink area.

[0018] Beneficial effects of the utility model:

[0019] The bottom wall of the cooking pot provided by the present invention includes a sinking area, multiple support areas, and multiple diversion areas. The multiple support areas and the multiple diversion areas are staggered around the sinking area. The height of the upper surface of the support area at the same horizontal distance from the center of the sinking area is higher than the height of the upper surface of the diversion area. The height of the upper surface of the diversion area is higher than the sinking area. The height of the upper surface of the diversion area gradually increases from the center of the sinking area to the outside. The support area is used to support the cooking utensils to prevent the cooking utensils from directly contacting the inner side of the sinking area and hindering the entry of cooking water; the diversion area is used to guide the cooking water to flow toward the sinking area, and the sinking area is used to receive the cooking water. Since the height of the upper surface of the support area at the same horizontal distance from the center of the sinking area is higher than the height of the upper surface of the diversion area, that is, there is a height difference between the support area and the diversion area, the support area can guide the cooking water to flow toward the diversion area, and the cooking utensils will not hinder the flow of cooking water. At the same time, since the upper surface of the diversion area gradually increases in height from the center of the sinking area to the outside, it can guide the cooking water from the diversion area to the sinking area, so that the cooking water flows smoothly into the sinking area, avoiding problems such as explosion caused by excessive temperature due to dry burning in the sinking area.

[0020] The cooking appliance provided by the present invention includes the aforementioned cooking liner. The support area of the cooking liner guides the cooking water to the diversion area. Furthermore, the diversion area does not directly contact the cooking vessel, thus preventing the cooking vessel from obstructing the flow of the cooking water. Furthermore, the diversion area guides the cooking water smoothly into the sink area, preventing problems such as frying caused by excessive temperatures in the sink area due to dry cooking, thereby extending the service life of the cooking liner.

[0040] Example 1

[0041] like Figures 1 to 6 As shown, the cooking vessel 100 has a cooking cavity 10 containing high-temperature steam, which cooks the food in the cooking container 100. During the cooking process, some of the high-temperature steam condenses to form cooking water, which drips and collects at the bottom of the cooking cavity 10. The cooking vessel 100 includes a bottom wall 11 and surrounding upright side walls 12.

[0042] Bottom wall 11 includes a sunken platform 111, multiple support areas 112, and multiple diversion areas 113. These support areas 112 and diversion areas 113 are staggered around sunken platform 111. The upper surfaces of support areas 112, at the same horizontal distance from the center of sunken platform 111, are higher than the upper surfaces of diversion areas 113. The upper surfaces of diversion areas 113 are also higher than those of sunken platform 111. The upper surfaces of diversion areas 113 gradually increase in height from the center of sunken platform 111 outward. Support areas 112 support the cooking vessel 100, preventing it from directly contacting the inner surface of sunken platform 111 and obstructing the entry of cooking water. Diversion areas 113 guide the cooking water toward sunken platform 111, which receives the cooking water. Because the upper surface of support area 112, located at the same horizontal distance from the center of sink area 111, is higher than the upper surface of diversion area 113, i.e., there is a height difference between support area 112 and diversion area 113, support area 112 can guide the cooking water toward diversion area 113. Furthermore, cooking vessel 100 does not obstruct the flow of cooking water. Furthermore, because the upper surface of diversion area 113 gradually increases in height from the center of sink area 111 outward, it can guide the cooking water from diversion area 113 toward sink area 111, allowing the cooking water to flow smoothly into sink area 111, thus preventing problems such as boiling in sink area 111 due to excessive temperatures caused by dry cooking.

[0043] Specifically, a portion of the bottom wall 11 surrounding the sink area 111 has multiple grooves that are concave downward. These grooves are spaced apart to form multiple diversion areas 113. The bottom wall 11 between adjacent diversion areas 113 forms a support area 112. The grooves extend toward the side wall 12 of the cooking pot. These linear grooves reduce the flow resistance of the cooking water and extend over a long distance, allowing them to gather and guide more cooking water. In order to increase the number of water-guiding channels and improve the diversion capacity for the cooking water, so that the cooking water throughout the entire area of the bottom wall 11 is evenly diverted, multiple grooves are provided, and the multiple grooves are spaced apart in a divergent pattern along the circumference of the sink area 111.

[0044] The width of the upper opening of the groove gradually increases outward from the center of the sinking area 111. Figure 3 As shown in the figure, L2 is the width of the upper opening of the groove, L1 is the width of the bottom surface of the groove, and L2 gradually increases outward from the center of the sink area 111 to ensure that more cooking water enters the upper opening of the groove.

[0045] In one embodiment, the width L2 of the upper opening of the groove is greater than the width L1 of the bottom surface of the groove. To ensure that cooking water can flow smoothly into the sink area 111 through the groove, the minimum value of the width L1 of the bottom surface of the groove is 3 mm.

[0046] The depth of the groove gradually increases from the center of the sinking area 111 to the outside. Figure 3 As shown in the figure, H4 is the depth of the groove, that is, the vertical distance from the upper opening of the groove to the bottom surface. H4 gradually increases outward from the center of the sink area 111, so that the volume of the groove is larger and can guide more cooking water.

[0047] The height of the upper surface of the support area 112 gradually increases from the center of the sinking area 111 outward. That is, in the first embodiment, the support area 112 is tilted downward from the edge toward the sinking area 111, which is conducive to guiding the cooking water in the support area 112 to flow to the guide area 113 and the sinking area 111, and the cooking water will not be retained in the support area 112. Figure 2 and Figure 3 As shown in FIG, the height distance H1 between the upper surface of the support area 112 and the sunken surface 1111 of the sinking area 111 is the height of the upper surface of the support area 112. The value of H1 ranges from 6 mm to 9 mm. A sufficient height difference ensures the flow of cooking water toward the sinking area 111.

[0048] To enhance the ability of bottom wall 11 to guide cooking water, it has a first inclined surface 114 and a second inclined surface 115. The first inclined surface 114 surrounds the recessed area 111 and slopes downward from the edge to one end of the recessed area 111. The second inclined surface 115 surrounds the first inclined surface 114, with a greater angle than the first inclined surface 114. A groove is defined in the first inclined surface 114. Cooking water dripping down the sidewall 12 falls onto the bottom wall 11. The second inclined surface 115 guides the cooking water, directing it into the first inclined surface 114 and into the groove.

[0049] The sinking area 111 has a sunken surface 1111 and a side wall surface 1112 surrounding the sunken surface 1111. The side wall surface 1112 is inclined from the lower end to the upper end toward the center direction away from the sunken surface 1111. Moreover, the upper end of the side wall surface 1112 and the first inclined surface 114 are connected by an arc surface transition, thereby avoiding the drop in the cooking water flow path and reducing the flow resistance of the cooking water.

[0050] The top surface of the groove and the first inclined surface 114 are also connected by a transitional arc surface, so that the cooking water on the first inclined surface 114 can flow into the groove.

[0051] Example 2

[0052] This second embodiment provides a cooking liner having a cooking cavity 10. High-temperature steam is contained within the cooking cavity 10. During the cooking process, some of the high-temperature steam condenses to form cooking water, which drips and gathers at the bottom of the cooking cavity 10. A bottom wall 11 includes a sinking area 111, multiple support areas 112, and multiple guide areas 113. The multiple support areas 112 and the multiple guide areas 113 are staggered around the sinking area 111. The upper surfaces of the support areas 112 at the same horizontal distance from the center of the sinking area 111 are higher than the upper surfaces of the guide areas 113. The upper surfaces of the guide areas 113 are also higher than the sinking area 111. The upper surfaces of the guide areas 113 gradually increase in height from the center of the sinking area 111 outward. The support area 112 is used to support the cooking vessel 100, preventing the cooking vessel 100 from directly contacting the inner surface of the sink area 111 and obstructing the entry of cooking water; the diversion area 113 is used to guide the cooking water to flow toward the sink area 111, and the sink area 111 is used to receive the cooking water. Since the height of the upper surface of the support area 112, which is at the same horizontal distance from the center of the sink area 111, is higher than the height of the upper surface of the diversion area 113, that is, there is a height difference between the support area 112 and the diversion area 113, the support area 112 can guide the cooking water to flow toward the diversion area 113, and the cooking vessel 100 will not hinder the flow of cooking water. At the same time, since the upper surface of the diversion area 113 gradually increases in height from the center of the sink area 111 to the outside, it can guide the cooking water from the diversion area 113 to the sink area 111, allowing the cooking water to flow smoothly into the sink area 111, avoiding problems such as boiling caused by excessive temperature in the sink area 111 due to dry burning.

[0053] The difference of the second embodiment is that Figures 7 to 12 As shown, a recessed area 111 is located at the center of the bottom wall 11. A portion of the bottom wall 11 surrounding the recessed area 111 has multiple upwardly projecting ribs. These ribs are spaced apart to form multiple support areas 112. The bottom wall 11 between adjacent support areas 112 forms a diversion area 113. The ribs extend toward the sidewalls 12 of the cooking pot, extending the water diversion path of the diversion area 113 and enabling it to gather and guide more cooking water. Multiple ribs are spaced apart in a diverging pattern around the perimeter of the recessed area 111 to form multiple, spaced diversion areas 113, improving the diversion capacity of the cooking water.

[0054] The width of the bottom of the rib gradually decreases from the center of the sinking area 111 to the outside. Figure 8 and Figure 9 As shown, W2 is the bottom width of the rib. This provides excellent structural strength and load-bearing properties, ensuring stable support for cooking vessel 100. Even with heavy food, the rib remains stable and resists deformation. The top width W1 of the rib is smaller than the bottom width W2. To ensure stable support for cooking vessel 100, the minimum top width W1 is 4 mm.

[0055] The thickness of the rib decreases gradually from the bottom to the top along the center of the sinking area 111 outward. Figure 9 As shown in the figure, H2 is the thickness of the rib, that is, the height distance between the top of the rib and the diversion area 113. The value of H2 ranges from 6mm to 12mm. Because the thickness of the rib determines the depth of the diversion area 113, sufficient thickness can ensure the volume and water diversion performance of the diversion area 113.

[0056] The height of the upper surface of the support area 112 formed by the ribs is flush outward from the center of the sink area 111, which provides a more stable support for the cooking vessel 100 and prevents the cooking vessel 100 from tilting or sliding.

[0057] In order to ensure that the cooking water flows from the diversion area 113 toward the sinking area 111, Figure 10 As shown, bottom wall 11 has a first inclined surface 114 and a second inclined surface 115. Second inclined surface 115 surrounds first inclined surface 114, with the angle of second inclined surface 115 greater than that of first inclined surface 114. First inclined surface 114 surrounds the perimeter of sink area 111. A rib protrudes from first inclined surface 114 and extends to second inclined surface 115. Second inclined surface 115 also forms part of diversion area 113, further enhancing its water-conducting capacity. The inclined first inclined surface 114 serves as the bottom surface of diversion area 113, guiding cooking water and ensuring its fluidity. This prevents any stagnation within diversion area 113.

[0058] In one embodiment, the top of the rib extends to be flush with the highest point of the second inclined surface 115, such as Figure 11 and Figure 12 shown.

[0059] In this embodiment, the sinking area 111 has a sunken surface 1111 and a side wall surface 1112 surrounding the sunken surface 1111. The lower end to the upper end of the side wall surface 1112 are inclined toward the center direction away from the sunken surface 1111. Moreover, the upper end of the side wall surface 1112 and the first inclined surface 114 are connected by a circular arc surface transition. The guide area 113 is connected to the sinking area 111 through this circular arc surface, avoiding the drop in the flow path of the cooking water and reducing the flow resistance of the guide area 113.

[0060] Example 3

[0061] A third embodiment of the present invention provides a cooking appliance comprising a cooking liner as described in the first or second embodiment, and further comprising a heater 200 disposed outside the cooking liner for heating cooking water within a sink area 111. The bottom wall 11 comprises a sink area 111, a plurality of support areas 112, and a plurality of diversion areas 113. The plurality of support areas 112 and the plurality of diversion areas 113 are staggered around the sink area 111. The upper surfaces of the support areas 112, which are located at the same horizontal distance from the center of the sink area 111, are higher than the upper surfaces of the diversion areas 113. The upper surfaces of the diversion areas 113 are higher than the sink area 111, and the upper surfaces of the diversion areas 113 gradually increase in height outward from the center of the sink area 111. The support areas 112 are capable of guiding the cooking water toward the diversion areas 113. Furthermore, the diversion areas 113 do not directly contact the cooking vessel 100, and the cooking vessel 100 does not obstruct the flow of cooking water. At the same time, the guide area 113 can guide the cooking water to flow smoothly into the sink area 111, avoiding the sink area 111 from exploding due to excessive temperature caused by dry burning, thereby improving the service life of the cooking pot.

[0062] The heating element 200 is located below the sinking area 111, and the distance between the heating element 200 and the outer side of the sinking area 111 is H3 (refer to Figure 3 ), the value range of H3 is 6mm~10mm, which can ensure the effective heating of the cooking water received by the sink area 111 and avoid the heating temperature being too high.

[0063] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
