Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to a heating type rice cooker top cover. Background Technology
[0002] Rice cookers are a common household appliance, popularized for their ease of use and one-button cooking. Currently, rice cookers heat food via a heating plate at the bottom. During cooking, heat is conducted upwards through the heating plate, resulting in temperature differences in the rice inside the rice cooker. Rice near the bottom of the heating plate is prone to burning, while rice further away from the top is prone to being undercooked. This leads to poor overall cooking results. Furthermore, the burnt bottom requires more cleaning, potentially shortening the lifespan of the rice cooker's inner pot. Additionally, single-bottom heating can cause localized overheating, leading to the loss of vitamins and other nutrients. When cooking porridge, especially large-grained foods like black beans, red beans, soybeans, and peanuts, there are issues with long heating times and low efficiency. Furthermore, these foods often remain tough even after prolonged cooking. Therefore, this invention discloses a heating element on the top cover of a rice cooker. By adding a heating function to the top cover and combining it with a bottom heating plate, it achieves all-around heating of the food. This avoids uneven heating during the cooking process, which can lead to poor cooking results, long cooking times, loss of nutrients, and negative impacts on the taste of the food. It also significantly improves cooking efficiency and is worthy of widespread adoption. Summary of the Invention
[0003] The purpose of this invention is to design a heating top cover for a rice cooker to solve the problem of uneven heating during daily rice cooking. Combined with a bottom heating element, it provides all-around heating of the food inside the rice cooker, greatly improving heating efficiency and ensuring the food's texture and flavor. The specific technical solution is as follows:
[0004] A heating type electric rice cooker lid includes an IMD panel, a plastic panel, a heating liner, and a support ring. The IMD panel, plastic panel, heating liner, and support ring are fixedly arranged from top to bottom and hinged to the rice cooker body via a rear cover plate. The inner ring of the support ring has a circular hole for fixing a stainless steel lid, and its size is perfectly fitted to the stainless steel lid. A sealing ring is provided at the connection between the two. The heating liner has a fixing hole and a heating structure. The fixing hole is located at the rear of the heating liner and a steam cover is fixed in the hole. The heating structure is located in the center of the lower part of the heating liner and is circular in shape, with an area smaller than that of the stainless steel lid. The heating structure has an arc-shaped notch for fitting the edge of the fixing hole. A heating wire is installed in the heating structure and is connected to the main control circuit of the rice cooker. It heats and stores the food in the inner pot with electricity, and combined with the bottom heating plate, it heats the food from all directions, ensuring that the food is heated evenly during cooking and eliminating temperature differences. At the same time, the heating wire is electrically heated to prevent water vapor from condensing inside the lid, which would further damage the taste of the food.
[0005] Furthermore, limiting holes are provided at corresponding positions on the front of both the IMD panel and the plastic panel. The limiting holes are used to fix and place the lid opening button, which facilitates one-button cooking operation.
[0006] Furthermore, steam holes are provided at corresponding positions on the rear of the IMD panel and the plastic panel. These steam holes are positioned above the fixing holes to ensure a proper steam dissipation path.
[0007] Furthermore, the steam cover is provided with steam holes, which facilitate the discharge of steam heat from the pot and ensure safety.
[0008] Furthermore, the heated lining is provided with several reinforcing ribs to increase the stability and safety of the cover.
[0009] Furthermore, the steam vent is in a straight line shape, which facilitates the subsequent steam discharge without emitting more heat.
[0010] Furthermore, the stainless steel cover is provided with several through holes, which are positioned directly below the fixing hole. The through holes are circular in shape and are evenly distributed below the fixing hole, serving as the first channel for steam discharge.
[0011] The above technical solution can achieve the following beneficial effects:
[0012] Compared with existing technologies, the heating top-lid rice cooker disclosed in this utility model achieves the function of heating the top of the food inside the rice cooker, and combined with the bottom heating plate to heat the bottom of the food, so as to achieve the purpose of heating the food in all directions, ensuring that the rice grains are heated evenly, and that the rice grains at the bottom and top fully absorb water, so as not to cause the problems of burning or undercooking due to uneven heating. It improves the uniformity of heating, ensures the soft and glutinous taste, and reduces the loss of nutrients, which is worth promoting. Attached Figure Description
