[0035] The following is for reference. Figures 1-8 A steam cooking appliance 100 according to an embodiment of the present invention is described.

[0036] The steam cooking appliance 100 according to an embodiment of the present invention may include: an inner pot 1 and a heating element 3.

[0037] like Figures 1-8 As shown, the steam cooking appliance 100 in this embodiment of the invention can be a steam oven, or it can be other steam cooking appliances 100, which are not limited here.

[0038] In the prior art, the heating element of a steam cooking appliance is usually located on the lower surface of the top wall of the inner pot. The heat radiation generated by the heating element is easily transferred to the front panel of the steam cooking appliance, causing the front panel temperature to be too high, and further conducted to the oven door. Since electrical components are installed inside the oven door, excessive temperature can cause electrical component failure, affecting the service life of the steam cooking appliance.

[0039] Therefore, in this embodiment of the invention, the heating element 3 is placed in the upward recessed mounting recess 111 on the top wall 11 of the inner liner 1, so that the side wall 1112 of the mounting recess 111 can block the heat radiation generated by the heating element 3, prevent the heating element 3 from radiating heat to the surroundings, and thus prevent the heat radiation generated by the heating element 3 from being transferred to the front panel and oven door 5 of the steam cooking appliance 100, thereby protecting the electrical components inside the oven door 5.

[0040] The cooking cavity 2 is defined within the inner liner 1 of the steam cooking appliance 100. The cooking cavity 2 can hold food and is suitable for steaming within the cooking cavity 2. The inner liner 1 is isolated between the cooking cavity 2 and the outer shell, which can insulate heat and play a role in keeping the food warm and moist, thereby improving the cooking effect.

[0041] Furthermore, a heating element 3 is provided on the top wall 11 of the inner pot 1 of the steam cooking appliance 100. When the steam cooking appliance 100 is in the steaming mode, the heating element 3 on the top wall 11 of the inner pot 1 can also heat the top wall 11 of the inner pot 1, preventing steam from condensing on the surface of the top wall 11 of the inner pot 1, thereby preventing condensation from dripping onto the surface of the food and improving the taste of the food.

[0042] Furthermore, at least a portion of the inner surface of the top wall 11 of the inner liner 1 has an upwardly recessed mounting recess 111. The heating element 3 is disposed in the mounting recess 111. Since the inner liner 1 has the function of isolating heat diffusion, the mounting recess 111 formed by the top wall 11 of the inner liner 1 also has the function of isolating heat diffusion. Thus, the heat radiation generated by the heating element 3 can only radiate downwards to heat the food in the cooking cavity 2 located below, and will not radiate heat to the surroundings to heat the oven door 5 and the electrical components inside the oven door 5.

[0043] Therefore, the steam cooking appliance 100 can use the side wall 1112 of the mounting recess 111 to block the heat radiation generated by the heating element 3, prevent the heating element 3 from radiating heat to the surroundings, and thus prevent the heat radiation generated by the heating element 3 from being transferred to the front panel and oven door 5 of the steam cooking appliance 100, thereby protecting the electrical components inside the oven door 5.

[0044] According to an embodiment of the present invention, the steam cooking appliance 100 can reduce the heat radiated by the heating element 3 to the surroundings, ensure the temperature of the oven door 5 and the electrical components inside the oven door 5 during the cooking process, and improve the service life of the steam cooking appliance 100.

[0045] Of course, the steam cooking appliance 100 in this embodiment of the invention can be a steam-grill combination oven, which has a steaming mode, a grilling mode, and a steam-grilling mode. In the grilling mode or the steam-grilling mode, the heating element 3 installed on the top wall 11 of the inner liner 1 of the steam cooking appliance 100 heats the food in the cooking cavity 2. Furthermore, when the steam cooking appliance 100 is in the steaming mode, the heating element 3 installed on the top wall 11 of the inner liner 1 heats the top wall 11 of the inner liner 1, preventing steam from condensing on the surface of the top wall 11 of the inner liner 1, thereby preventing condensation from dripping onto the food surface and improving the taste of the food.

[0046] like Figure 7As shown, directly placing the heating element 3 on the top wall 11 of the inner pot 1 will cause the top wall 11 of the inner pot 1 to become too hot. The top wall 11 will discolor or the coating will peel off due to the high temperature. Furthermore, the top wall 11 of the inner pot 1 will transfer heat to the front panel of the steam cooking appliance 100, causing the front panel to become too hot, and further conduction to the oven door 5. Since electrical components are installed inside the oven door 5, the high temperature will cause the electrical components to malfunction, affecting the service life of the steam cooking appliance 100.

[0047] Therefore, leaving a certain gap between the heating element 3 and the top wall 11 of the inner liner 1 can ensure that the heat of the heating element 3 is transferred to the top wall 11 of the inner liner 1 while avoiding the temperature of the top wall 11 from getting too high. It can also ensure that steam does not condense on the surface of the top wall 11 of the inner liner 1 while avoiding discoloration or coating peeling of the top wall 11 due to excessive temperature.

[0048] Specifically, since the heating element 3 is disposed in the mounting recess 111, the heating element 3 can heat the bottom wall 1111 of the mounting recess 111, ensuring that steam will not condense on the surface of the bottom wall 1111 of the mounting recess 111. There is a gap between the heating element 3 and the bottom wall 1111 of the mounting recess 111, which can ensure that the heat of the heating element 3 is transferred to the bottom wall 1111 of the mounting recess 111 while avoiding the temperature of the bottom wall 1111 from becoming too high. It also ensures that steam will not condense on the surface of the bottom wall 1111 of the mounting recess 111 while preventing the bottom wall 1111 from discoloring or peeling off due to excessive temperature.

[0049] According to some embodiments of the present invention, the gap between the heating element 3 and the bottom wall 1111 of the mounting recess 111 is 3mm-10mm. That is, the gap between the heating element 3 and the bottom wall 1111 is limited to between 3mm and 10mm. For example, the gap between the two can be 3mm, 5mm, 7mm, 10mm, etc.

[0050] Therefore, by limiting the gap between the heating element 3 and the bottom wall 1111 of the mounting recess 111 to the above range, it is possible to ensure that the heat of the heating element 3 can be transferred to the bottom wall 1111 of the mounting recess 111 while avoiding the temperature of the bottom wall 1111 from becoming too high. It is also possible to ensure that steam does not condense on the surface of the bottom wall 1111 of the mounting recess 111 while avoiding discoloration or coating peeling of the bottom wall 1111 due to excessive temperature.

[0051] Combination Figure 4 , Figure 5 and Figure 7As shown, there are areas on the top wall 11 of the inner pot 1 where the heat transfer of the heating element 3 is insufficient. Steam will condense at these areas, producing condensate droplets. To prevent the condensate droplets from falling onto the food inside the cooking cavity 2, a guide surface 1113 is provided on the inner surface of the top wall 11 of the inner pot 1 to guide the condensate droplets to the side wall of the inner pot 1 or other locations that will not affect the cooking of the food. This prevents the condensate droplets from falling onto the surface of the food and improves the taste of the food.

[0052] Since the heating element 3 can prevent condensation from dripping onto the food surface even if the part with the guide surface 1113 is not heated to a high temperature, this part of the heating element 3 can be placed away from this part. During the cooking process, the temperature of the electrical components located near this part will not increase significantly, thus protecting the electrical components on this side and improving the service life of the steam cooking appliance 100.

[0053] Specifically, the guide surface 1113 is located on at least one side of the bottom wall 1111 of the mounting recess 111; in other words, the guide surface 1113 is located on one or more sides of the mounting recess 111. The arrangement of the guide surface 1113 can be configured according to the distribution of the electrical components of the steam cooking appliance 100, so as to leave a lower temperature portion between the electrical components and the heating element 3 and guide the condensate generated in this portion.

[0054] Furthermore, the guide surface 1113 gradually extends downward along the bottom wall 1111 away from the mounting recess 111, so that the condensate can be guided from the position near the bottom wall 1111 of the mounting recess 111 to the position away from the bottom wall 1111 of the mounting recess 111 under the action of gravity.

[0055] Since the mounting recess 111 is usually located at the center of the top wall 11 of the inner liner 1, and the food in the cooking cavity 2 is usually placed in the center of the cooking cavity 2 for heating, the heating effect is better. The bottom wall 1111 near the mounting recess 111 is closer to the food, while the bottom wall 1111 away from the mounting recess 111 is farther away. Therefore, guiding the condensate from the bottom wall 1111 near the mounting recess 111 to the bottom wall 1111 away from the mounting recess 111 allows the condensate droplets to flow to the edge of the cooking cavity 2 without affecting the food's cooking position, preventing condensate droplets from falling on the food surface and improving the food's texture.

[0056] like Figure 4 and Figure 5 As shown, at least a portion of the surface of the sidewall 1112 of the mounting recess 111 forms a guide surface 1113 to guide condensate at the sidewall 1112 of the mounting recess 111.

[0057] One end of the guide surface 1113 extends to or near the side wall of the inner liner 1 to guide condensate droplets to the side wall or near the side wall of the inner liner 1. Since the lower part of the side wall or near the side wall of the inner liner 1 is away from the food, guiding the condensate droplets to the side wall or near the side wall of the inner liner 1 prevents condensate droplets from falling on the surface of the food, thus improving the taste of the food. Furthermore, the condensate can flow downwards along the side wall of the inner liner 1 and into the bottom of the inner liner 1, which is beneficial for the recovery of condensate.

[0058] Reference Figure 4 The mounting recess 111 has a bottom wall and a first side wall 11121. The guide surface 1113 is provided on the first side wall 11121 of the mounting recess 111. For the first side wall 11121 with the guide surface 1113, even if the heating element 3 does not heat the first side wall 11121 with the guide surface 1113 to a high temperature, it can prevent the condensed water formed on the first side wall 11121 from dripping onto the food surface. Therefore, the distance between the heating element 3 and the first side wall 11121 can be set to be relatively far.

[0059] Furthermore, for other sidewalls 1112 without a flow guide surface 1113, the heating element 3 needs to heat the sidewall 1112 to a higher temperature to avoid condensation on the sidewall 1112, thereby preventing the condensed water from dripping onto the food surface. Therefore, the distance between the heating element 3 and other sidewalls 1112 needs to be set closer.

[0060] In other words, the distance between the heating element 3 and the first side wall 11121 of the mounting recess 111 is greater than the distance between the heating element 3 and any one of the other side walls 1112 of the mounting recess 111, so as to reasonably arrange the position of the heating element 3 and ensure the electrical safety of the steam cooking appliance 100 while ensuring that condensate does not drip onto the food.

[0061] Reference Figure 4 The distance between the heating element 3 and the first sidewall 11121 of the mounting recess 111 is shown as L1, and the distance between the heating element 3 and the other sidewalls 1112 of the mounting recess 111 that are not provided with guide surfaces 1113 is shown as L2. Figure 4 As shown, L1 is greater than L2.

[0062] Combination Figure 1 , Figure 4 , Figure 5 and Figure 7In the illustrated embodiment, since there are more electrical components at the oven door 5 in the steam cooking appliance 100, the distance between the oven door 5 and the heating element 3 should be set further to avoid excessive heat generated by the heating element 3 being transferred to the oven door 5 of the steam cooking appliance 100. This ensures the temperature of the oven door 5 and the electrical components inside the oven door 5 during the cooking process of the steam cooking appliance 100, thereby improving the service life of the steam cooking appliance 100.

[0063] Because the distance between the oven door 5 and the heating element 3 is set further, the temperature in the area between the oven door 5 and the heating element 3 is lower, and steam may condense here, producing condensate. Therefore, it is necessary to guide the condensate produced in this area. Therefore, by setting the guide surface 1113 on the side of the bottom wall 1111 of the mounting recess 111 near the oven door 5, the condensate formed on the bottom wall 1111 of the mounting recess 111 near the oven door 5 can be guided to the vicinity of the side wall of the inner liner 1, ensuring that the condensate does not drip onto the food.

[0064] According to some embodiments of the present invention, with reference to Figure 2 , Figure 6 , Figure 7 and Figure 8 At least a portion of the top wall 11 of the inner liner 1 protrudes upward, thereby forming a protrusion 112 on the outer surface of the top wall 11 of the inner liner 1 and an installation recess 111 on the inner surface of the top wall 11 of the inner liner 1. The structure is simple and convenient for the processing and manufacturing of the inner liner 1.

[0065] like Figure 2 As shown, multiple ribs 1121 are provided on the top wall 11 of the protrusion 112. The ribs 1121 can strengthen the structural strength of the top wall 11 of the inner pot 1 and the protrusion 112 formed on the outer surface of the top wall 11 of the inner pot 1, ensure the stability of the protrusion 112, and prevent the protrusion 112 from deforming, which would affect the performance of the steam cooking appliance 100.

[0066] Furthermore, the rib 1121 extends to the side wall 1112 of the protrusion 112 to strengthen the connection stability between the bottom wall 1111 of the mounting recess 111 and the side wall 1112, ensuring the shape stability of the protrusion 112 at all points and ensuring the stability of the flow guided by the first side wall 11121.

[0067] According to some embodiments of the present invention, the top wall 11 of the inner liner 1 is made by stamping process, so as to facilitate the processing and manufacturing of the inner liner 1 and reduce the processing cost of the inner liner 1.

[0068] like Figures 3-5 As shown, the steam cooking appliance 100 also includes: a mounting bracket 4, which facilitates the installation of the heating element 3, ensures the stability of the heating element 3, and ensures that the heating element 3 can stably heat below the top wall 11 of the inner pot 1.

[0069] The mounting bracket 4 is located on the top wall 11 of the inner liner 1. The mounting bracket 4 can stably set the heating element 3 on the top wall 11 of the inner liner 1, and the mounting bracket 4 can support and fix the heating element 3 below the top wall 11 of the inner liner 1, ensuring that the heating element 3 can stably heat the food and the top wall 11 at a certain position below the top wall 11 of the inner liner 1.

[0070] Reference Figures 3-5 The heating element 3 forms a heating tube to facilitate the installation of the heating element 3 and reduce the processing cost of the steam cooking appliance 100.

[0071] Furthermore, the mounting bracket 4 includes: a first bracket 41 and / or a second bracket 42.

[0072] Specifically, the mounting bracket 4 includes at least one first bracket 41. A portion of the first bracket 41 is sleeved on the heating tube to limit and fix the heating tube, ensuring that the heating tube will not fall off the first bracket 41. The other portion of the first bracket 41 is connected to the bottom wall 1111 of the mounting recess 111 to support and fix the first bracket 41 and the heating tube fixedly limited on the first bracket 41 below the bottom wall 1111 of the mounting recess 111.

[0073] Preferably, there can be multiple first supports 41 to ensure that the forces on each first support 41 are balanced, thereby further ensuring the stability of the heating tube installation.

[0074] The mounting bracket 4 includes a second bracket 42, which is connected to both ends of the heating tube to fix and limit the two ends of the heating tube on the second bracket 42, ensuring that the two ends of the heating tube will not contact each other and cause a short circuit, and ensuring that the two ends of the heating tube maintain a certain distance to facilitate connection with the wiring harness. The second bracket 42 is connected to the side wall 1112 of the mounting recess 111 to fix the two ends of the heating tube on the side wall 1112 of the mounting recess 111, and to allow the two ends of the heating tube to pass through the side wall 1112 of the mounting recess 111, so as to facilitate connection between the two ends of the heating tube and the external wiring harness.

[0075] like Figure 3As shown, the first bracket 41 includes a mounting sleeve 411 and a connecting portion 412. The mounting sleeve 411 is fitted onto the heating tube to limit and fix the heating tube, ensuring that the heating tube will not fall off the first bracket 41. The connecting portion 412 is connected to the bottom wall 1111 of the mounting recess 111 to support and fix the first bracket 41 and the heating tube fixedly limited on the first bracket 41 below the bottom wall 1111 of the mounting recess 111. The connecting portion 412 defines a gap between the heating tube and the bottom wall 1111 of the mounting recess 111, ensuring that the heat from the heating tube can be transferred to the bottom wall 1111 of the mounting recess 111 while preventing the bottom wall 1111 from becoming too hot. This also ensures that steam will not condense on the surface of the bottom wall 1111 of the mounting recess 111, preventing discoloration or coating peeling due to excessive temperature.
