Description

Technical Field

[0001] This utility model relates to the field of small household appliances, specifically to a cooking utensil. Background Technology

[0002] Common cooking appliances such as rice cookers only have a heating structure at the bottom of the inner pot. The heat can only cover the bottom of the inner pot and the side near the bottom. When the capacity of the food in the inner pot is large, the heat at the bottom is concentrated, which can cause the food at the bottom to burn, while the food in the higher parts of the side is not heated enough and has a poor taste. This results in poor overall taste consistency and affects the user experience.

[0003] To improve the uniformity of food heating, existing patent CN201822067552.0 discloses a cooking appliance with a heating device at the bottom of the inner pot and infrared heating elements at the top and sides. This multi-directional heating improves heating efficiency and uniformity. Specifically, regarding the side heating structure, the aforementioned patent uses a C-shaped heating tube. However, its heat can only cover a portion of the inner pot's circumference. The temperature is lower at the cold end of the heating tube on the side of the inner pot, resulting in insufficient heating of the food in that area. This still leads to uneven heating and poor taste.

[0004] While some heaters in other fields employ planar spiral heating elements to expand the heating range and ensure the entire container is heated, this type of heating structure has not yet been applied to rice cookers. Upon discovering the aforementioned problem, the applicant of this application improved the heating structure of the rice cooker in an effort to achieve uniform heating, enhance the overall taste of the food, and thus improve the user experience. Utility Model Content

[0005] This utility model provides a cooking appliance that aims to solve the technical problem that the heating structure on the side of the inner pot of existing rice cookers can only heat a part of the circumferential area of ​​the inner pot, resulting in insufficient local heating and affecting the uniformity of food heating.

[0006] This utility model discloses a cooking appliance, including a pot body and a lid. The pot body has an inner pot with a cooking cavity. The bottom of the inner pot is provided with a heating element. The side of the pot body is provided with an infrared heating element for radiating infrared rays into the cooking cavity. The infrared heating element includes a tubular body and a wiring terminal at the end of the body. There is at least one infrared heating element. The body is arranged around the outer wall of the inner pot. The ends of two adjacent bodies are overlapped to form an annular heating zone on the outer side of the inner pot.

[0007] The cooking appliance of this utility model also has the following additional technical features:

[0008] The ends of two adjacent bodies are located at different heights so that the ends of the two adjacent bodies overlap in the vertical direction.

[0009] The ends of two adjacent bodies are located on the same horizontal plane so that the ends of the two adjacent bodies overlap in the radial direction.

[0010] A gap is provided between the ends of two adjacent bodies.

[0011] There are two infrared heating elements, and the bodies of the two infrared heating elements are arc-shaped and arranged around the inner pot.

[0012] The two infrared heating elements are located on the same horizontal plane so that the ends of the two adjacent bodies overlap in the radial direction.

[0013] The two infrared heating elements are located at different heights so that the ends of the two adjacent bodies overlap in the vertical direction.

[0014] The cooking appliance includes a controller, and there are two infrared heating elements. The controller is configured to control the two infrared heating elements to work independently, so as to regulate the working time and / or power of the two elements.

[0015] A cavity is formed between the pot body and the inner pot. A heat insulation component is provided in the cavity, which divides the cavity into an independent lower heating cavity and an upper heat preservation cavity. The infrared heating element is located in the lower heating cavity.

[0016] The lower heating cavity is provided with a reflective cover that covers the infrared heating element, and the inner wall of the reflective cover is provided with a reflective coating.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] 1. The cooking appliance of this utility model, by overlapping the ends of two adjacent bodies, eliminates obvious low-radiation areas, achieving a basically uniform heating effect throughout the entire circumference. It provides 360° radiation heating to the inner pot without dead angles, ensuring sufficient infrared radiation for food in all circumferential directions. This improves the uniformity of infrared heating, enhances the aroma of the food, and improves the consistency of its taste. By simultaneously operating the heating element and the infrared heating element, multiple heat sources can be used to heat the inner pot at the same time, ensuring thorough heating of the food, improving heating efficiency, and enhancing the uniformity of heating, thereby improving the taste of the food.

[0019] 2. Under the premise of achieving circumferential heating without dead angles in the inner pot, in order to cover more areas of the inner pot with the heat of the infrared heating element, the ends of two adjacent bodies are located at different heights so that the ends of the two adjacent bodies overlap in the vertical direction. Thus, the bodies are not set at one height, which can realize heating of the inner pot at different heights. This is beneficial to improve the uniformity of heating of the food distributed along the height of the inner pot and further improve the taste of the food.

[0020] 3. To enhance local heating effect while ensuring circumferential heating of the inner pot, the ends of two adjacent bodies are located on the same horizontal plane, so that the ends of the two adjacent bodies overlap in the radial direction. This makes the bodies set at the same height, which is convenient for installation. The overlapping area can provide more heat to the inner pot to meet the heating effect of specific ingredients in that area, thus enriching the user's processing needs.

[0021] 4. To reduce the probability of local food burning, a gap is provided between the ends of two adjacent bodies. This prevents heat from concentrating at the point where the ends are touching, which would prevent the heat from dissipating quickly and cause the food in the corresponding cooking area to burn, as well as affecting the service life of the infrared heating element.

[0022] 5. When two infrared heating elements are used, the bodies of the two infrared heating elements are arc-shaped and arranged around the inner pot. Compared with a single heating element with a longer circumference, the two infrared heating elements are easier to process, have a higher yield, and have better processing technology. Moreover, setting two infrared heating elements is conducive to individual control, which can provide a variety of heating methods, thereby improving the heating effect of different ingredients, enriching the processing variety of ingredients, and enhancing the user experience.

[0023] The two infrared heating elements can be located on the same horizontal plane, allowing the ends of the two adjacent bodies to overlap in the radial direction. This simplifies installation, and the overlapping area can provide more heat to the inner pot to meet the heating requirements of specific ingredients in that area, thus enriching the user's processing needs.

[0024] The two infrared heating elements can be located at different heights, allowing the ends of the two adjacent bodies to overlap in the vertical direction. This enables the inner pot to be heated at different heights, which helps to improve the uniformity of heating of the food distributed along the height of the inner pot and further improves the taste of the food.

[0025] 6. When two infrared heating elements are used, in order to achieve independent control of the two infrared heating elements, the cooking appliance includes a controller. The controller is configured to control the two infrared heating elements to work independently, so as to adjust the working time and / or power of the two elements. This can enrich the heating methods, provide more flexible heating solutions, and provide suitable solutions according to different ingredients to improve the cooking effect.

[0026] 7. To prevent insufficient heating at the top of the inner pot, which would affect the rate of water evaporation and thus cooking efficiency, resulting in soggy and unpalatable food, a cavity is formed between the pot body and the inner pot. This cavity is equipped with a heat insulation component, which divides the cavity into an independent lower heating cavity and an upper heat-preserving cavity. The infrared heating element is located in the lower heating cavity. The heat insulation component not only reduces the heat radiated from the infrared heating element to the pot body, thus lowering the probability of thermal deformation and extending its service life, but also prevents the pot body from becoming too hot to handle. Furthermore, the infrared heating element's location inside the heat insulation component facilitates heat concentration and radiation into the cooking cavity, improving heat utilization and heating efficiency, and preventing upward heat radiation from causing overheating and deformation of the plastic parts at the lid or damage to electronic components.

[0027] The heat insulation component divides the gap between the pot body and the inner pot into two chambers. The lower heating chamber provides the conditions for the placement of infrared heating elements, which can increase the temperature rise rate of the inner pot's side wall. This helps to make the heating rate of the food at the bottom and on the side more consistent, thereby improving the uniformity of heating and the taste of the food. The upper heat preservation chamber helps to maintain the temperature of the upper part of the inner pot. Because air has poor thermal conductivity, it can prevent heat loss from being too fast and prevent the rising steam from easily forming condensation, which would affect the rate of water evaporation. In other words, it helps to accelerate the evaporation of water in the inner pot and improve cooking efficiency.

[0028] Furthermore, the lower heating cavity is equipped with a reflector covering the infrared heating element. The inner wall of the reflector is coated with a reflective coating. The reflective coating can reflect the heat radiated by the infrared heating element towards the heat insulation component to the cooking cavity, which can improve the cooking efficiency in the cooking cavity and reduce the amount of heat reaching the surface of the pot body, thereby helping to lower the temperature of the pot body. Using a reflector to cover the infrared heating element is beneficial for heat concentration and has a good heat reflection effect. Moreover, the reflector and the heat insulation component can form a double-layer heat insulation structure, which can improve the heat insulation effect. Furthermore, the two are used as a single unit, which can simplify the installation steps. Attached Figure Description

[0047] like Figures 1 to 8As shown, this application provides a cooking appliance, including a pot body 10 and a lid 11. The pot body 10 has an inner pot 12 with a cooking cavity. The bottom of the inner pot 12 is provided with a heating element 13. The side of the pot body 10 is provided with an infrared heating element 14 for radiating infrared rays to the cooking cavity. The infrared heating element 14 includes a tubular body 141 and a terminal block 142 provided at the end of the body 141. At least one infrared heating element 14 is provided. The body 141 is arranged around the outer side wall of the inner pot 12. The ends of two adjacent bodies 141 are overlapped to form an annular heating zone on the outer side of the inner pot 12.

[0048] This invention relates to a cooking appliance where the ends of two adjacent main bodies 141 overlap, eliminating obvious low-radiation areas and ensuring consistent heating throughout the entire circumference. This allows for 360° radiation heating of the inner pot 12, ensuring sufficient infrared radiation for all parts of the food in the circumferential direction. This improves the uniformity of infrared heating, enhances the aroma of the food, and improves the consistency of its texture. By simultaneously operating the heating element 13 and the infrared heating element 14, multiple heat sources can be used to heat the inner pot 12 at the same time, ensuring thorough heating of the food within the inner pot 12, improving heating efficiency, enhancing the uniformity of heating, and ultimately improving the taste of the food.

[0049] The cooking appliance can be a rice cooker, in which case the infrared heating element 14 can radiate infrared rays into the inner pot 12 without any blind spots, which helps to enhance the aroma of the rice. The infrared heating effect on the rice is basically uniform in the circumferential direction, which helps to improve the consistency of the rice. The infrared heating element 14 can radiate infrared rays of multiple wavelengths into the cooking cavity during the cooking process. It has strong penetrability and can penetrate and heat the food, and stimulate the aroma of the food. For example, when the cooking appliance is a rice cooker, it can better stimulate the aroma of the rice, thereby improving the user's appetite. The heating element of the infrared heating element 14 can be carbon fiber, graphite, tungsten wire, silicon carbide, etc., and can be made into a tubular structure for use. This application does not make specific limitations in this regard.

[0050] It is understood that one or more infrared heating elements 14 can be provided. The overlapping ends can be the ends of the same body 141 or the ends of different bodies 141. The overlapping position can realize a closed loop of heat along the circumference. Compared with conventional heating elements with one-sided opening, it can eliminate the low radiation area of ​​heat, thereby achieving uniform heating of the inner pot 12 in the circumference. The overlapping length of the two ends is not less than 5mm to ensure the heating effect at the overlapping position.

[0051] In a preferred embodiment, the ends of two adjacent bodies 141 are located at different heights, so that the ends of the two adjacent bodies 141 overlap in the vertical direction. In this embodiment, the bodies 141 are not set at a single height, which enables heating of the inner pot 12 at different heights, which helps to improve the uniformity of heating of the food distributed along the height of the inner pot 12, and further improves the taste of the food.

[0052] In a preferred embodiment, the ends of two adjacent bodies 141 are located on the same horizontal plane, so that the ends of the two adjacent bodies 141 overlap in the radial direction. In this embodiment, the bodies 141 are set at the same height, which facilitates installation, and the overlapping area can provide more heat to the inner pot 12 to meet the heating effect of specific ingredients in that area, thus enriching the user's processing needs.

[0053] For example, glutinous rice and black rice are usually not as easy to cook as regular rice. When a user wants to mix glutinous rice and black rice into regular rice, in order to ensure that all ingredients are fully cooked under the same cooking time, the glutinous rice and black rice can be placed in the overlapping area of ​​the corresponding body 141. The heat in this area is higher, which can ensure that the glutinous rice and black rice are fully cooked, thus ensuring their taste.

[0054] As a preferred implementation method, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a gap 15 is provided between the ends of two adjacent bodies 141 to prevent heat from concentrating at the position when the ends are stuck together. This would prevent the heat from dissipating quickly, causing the food in the corresponding cooking area to burn and affecting the service life of the infrared heating element 14.

[0055] In the first implementation, such as Figures 1 to 3 As shown, the infrared heating element 14 is a single unit. Specifically, in one embodiment, as... Figure 3 As shown, the two ends of the body 141 are located at different heights so that the two ends of the body 141 overlap in the vertical direction, which can realize the heating of the inner pot 12 at different heights. This is beneficial to improve the uniformity of heating of the food distributed along the height of the inner pot 12 and further improve the taste of the food.

[0056] In another embodiment, such as Figure 2 As shown, the two ends of the body 141 are located on the same horizontal plane so that the two ends of the body 141 overlap in the radial direction, which facilitates installation. The overlapping area can provide more heat to the inner pot 12 to meet the heating effect of specific ingredients in that area and enrich the user's processing needs.

[0057] In the second implementation, such as Figures 4 to 7As shown, there are two infrared heating elements 14, and the bodies 141 of the two infrared heating elements 14 are arc-shaped and arranged around the inner pot 12.

[0058] Compared to a single heating element with a longer circumference, two infrared heating elements 14 are easier to process, have a higher yield, and have better processing technology. Moreover, setting two infrared heating elements 14 is conducive to individual control, which can provide a variety of heating methods, thereby improving the heating effect of different foods, enriching the types of food that can be processed, and enhancing the user experience.

[0059] In one embodiment, such as Figure 5 As shown, the two infrared heating elements 14 are located on the same horizontal plane so that the ends of the two adjacent bodies 141 overlap in the radial direction. Thus, the two bodies 141 are located on the same horizontal plane, which facilitates installation, and the overlapping area can provide more heat to the inner pot 12 to meet the heating effect of specific ingredients in that area, thus enriching the user's processing needs.

[0060] In another embodiment, the two infrared heating elements 14 are located at different heights so that the ends of adjacent bodies 141 overlap vertically. This allows the inner pot 12 to be heated at different heights, which improves the uniformity of heating of food distributed along the height of the inner pot 12 and further improves the taste of the food. Specifically, in one example, such as Figure 6 As shown, the two infrared heating elements 14 are positioned at opposite heights for easy installation. In another example, as... Figure 7 As shown, the two infrared heating elements 14 are arranged in a cross shape in space, that is, each body 141 has two different heights at both ends, which can enrich the arrangement of the infrared heating elements 14 and improve flexibility.

[0061] In one preferred embodiment, the cooking appliance includes a controller, and there are two infrared heating elements 14. The controller is configured to control the bodies 141 of the two infrared heating elements 14 to work independently, so as to regulate the working time and / or power of the two bodies 141. This is beneficial to enrich the heating forms, provide more flexible heating solutions, and provide suitable solutions according to different ingredients to improve the cooking effect.

[0062] For example, in one embodiment, when cooking an ingredient such as rice in the inner pot 12, the controller can control the two main bodies 141 to operate at the same power for the same duration, ultimately ensuring that the rice in each location has a consistent texture. The two main bodies 141 operating for the same duration can mean that the two main bodies 141 start working and stop heating at the same time, or that they work alternately but their total heating time is the same, which can be set according to actual needs.

[0063] In another embodiment, two ingredients, such as rice and black rice, are cooked in the inner pot 12. The rice and black rice are placed in areas of two separate bodies 141. Under the same working time, the body 141 corresponding to the black rice can operate at a relatively higher power, or under the same power, the body 141 corresponding to the black rice can be heated for a longer time so that both the rice and black rice are fully cooked and the taste of the ingredients is ensured.

[0064] The working modes of the two main bodies 141 are not limited to the above methods. They can be flexibly controlled according to different scenarios to improve the performance of cooking utensils.

[0065] In a preferred embodiment, a cavity 16 is formed between the pot body 10 and the inner pot 12. A heat insulation element 17 is provided in the cavity 16, which divides the cavity 16 into an independent lower heating cavity 161 and an upper heat preservation cavity 162. An infrared heating element 14 is disposed in the lower heating cavity 161.

[0066] like Figure 8 As shown, by setting the heat insulation component 17, the heat insulation component 17 can not only reduce the heat radiated from the infrared heating element 14 to the pot body 10, thereby reducing the probability of thermal deformation of the pot body 10 and extending its service life, but also prevent the pot body 10 from getting too hot to touch. Moreover, the infrared heating element 14 is located on the inside of the heat insulation component 17, which is conducive to the heat being concentrated and radiated to the cooking cavity, thereby improving the heat utilization rate, improving the heating efficiency, and preventing the upward radiation of heat from causing the plastic parts at the lid 11 to overheat and deform or the electronic components to overheat and be damaged.

[0067] The heat insulation component 17 divides the gap 15 between the pot body 10 and the inner pot 12 into two chambers. The lower heating chamber 161 provides conditions for the arrangement of the infrared heating element 14, which can increase the temperature rise rate of the side wall of the inner pot 12. This helps to make the heating rate of the food at the bottom and the food on the side more consistent, thereby improving the uniformity of the food heating and improving the taste of the food. The upper heat preservation chamber 162 helps to maintain the temperature of the upper part of the inner pot 12. Because air has poor thermal conductivity, it can prevent heat loss too quickly and prevent the temperature of the upper part of the inner pot 12 from being too low, which would cause the rising steam to easily form condensate and affect the rate of water evaporation. In other words, it helps to accelerate the evaporation of water in the inner pot 12 and improve cooking efficiency.

[0068] In one embodiment, the lower heating cavity 161 is provided with a reflector 18 covering the infrared heating element 14, and the inner wall of the reflector 18 is provided with a reflective coating.

[0069] The reflective coating can reflect the heat radiated by the infrared heating element 14 toward the heat insulation element 17 to the cooking cavity, which can improve the cooking efficiency in the cooking cavity and reduce the amount of heat reaching the surface of the pot body 10, thus helping to lower the temperature of the pot body 10. The infrared heating element 14 is covered by the reflector 18, which is conducive to the concentration of heat and has a better heat reflection effect. Moreover, the reflector 18 and the heat insulation element 17 can form a double-layer heat insulation structure, which can improve the heat insulation effect. Furthermore, the two are used as a single piece, which can simplify the installation steps.

[0070] In order to install the infrared heating element 14, a clamping member is provided on the inner surface of the reflector 18. The infrared heating element 14 is fixed to the reflector 18 by the clamping member, which can prevent the infrared heating element 14 from shifting or falling downwards and affecting the heating effect of the inner pot 12 side wall. It can also prevent the infrared heating element 14 from falling and causing excessive heat at the bottom, resulting in the food burning.

[0071] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
