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 from this structure can only cover the bottom of the inner pot and the sides near the bottom. When the amount of food in the inner pot is large, there is a problem that the heat is concentrated at the bottom, causing the food at the bottom to burn, while the food in the higher parts of the sides is not heated enough and has a poor taste. This results in poor overall heating of the food, poor taste, and affects the user experience.

[0003] To improve the uniformity of food heating, existing patent CN201822067598.2 discloses a cooking appliance with a main heating element located at the bottom of the inner pot and an auxiliary heating element located on the side of the inner pot. Specifically, the auxiliary heating element is positioned close to the main heating element. On the one hand, the heat from both the main and auxiliary heating elements is concentrated in the lower part of the inner pot. When processing a large volume of food, the upper part of the food is not heated enough, resulting in poor uniformity of heating effect from top to bottom. Moreover, the close proximity of the two heat sources makes it easy for the food in the heat-concentrated area to burn, leading to uneven heating of the food as a whole and affecting the overall taste. On the other hand, in the upper middle area of ​​the inner pot, the pot wall temperature is lower. When the rising steam encounters the lower temperature pot wall, it is easy to form condensation that then enters the food, resulting in slow evaporation of moisture from the food, making the upper part of the food too wet and soft, with a poor taste. Utility Model Content

[0004] This utility model provides a cooking appliance that aims to solve the technical problem that existing cooking appliances with multiple heat sources tend to have uneven heating of the food in the inner pot due to the relatively concentrated setting of multiple heat sources. In addition, the upper part of the inner pot is not heated enough and has a low temperature, which affects the evaporation rate of water and thus affects the cooking efficiency, resulting in the upper food being soggy and having a poor taste.

[0005] This utility model discloses a cooking appliance, including a pot body and a lid body. The pot body is provided with an inner pot having a cooking cavity and an infrared heating element. The infrared heating element is used to radiate infrared rays into the cooking cavity. A cavity is formed between the pot body and the inner pot. A heat insulation element is provided in the cavity, and the heat insulation element divides the cavity into a lower heating cavity and an upper heat preservation cavity. The infrared heating element is disposed in the lower heating cavity.

[0006] The cooking appliance of this utility model also has the following additional technical features:

[0007] The lower heating chamber is positioned to correspond to the cooking area of ​​the cooking chamber.

[0008] The upper end of the heat insulation component abuts against the outer wall of the inner pot to divide the cavity into an independent lower heating cavity and an upper heat preservation cavity.

[0009] The lower heating cavity is provided with a reflector covering the infrared heating element, and the reflector is fixed to the heat insulation element by fasteners.

[0010] The inner surface of the reflector is provided with a clamping member, and the infrared heating element is fixed to the reflector by the clamping member.

[0011] The heat insulation component includes an upper heat insulation part and a lower heat insulation part, which are vertically spliced ​​together.

[0012] The lower heating cavity is provided with a reflector covering the infrared heating element. The reflector includes a left reflector and a right reflector, which are connected by being spliced ​​together in a horizontal direction.

[0013] The reflector and the heat insulation component are provided with a communicating notch for the wiring of the infrared heating element to pass through.

[0014] The infrared heating element includes a tubular body and a wiring terminal at the end of the body. The infrared heating element is provided at least one. 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.

[0015] The heat insulation component includes a top wall and a side wall extending downward from the top wall. The top wall is arranged around the inner pot, and the bottom end of the side wall abuts against the bottom of the pot body. A heating plate is provided at the bottom of the inner pot, and the top end of the heating plate is flush with the bottom end of the side wall.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The cooking appliance of this utility model, by setting an infrared heating element on the side of the inner pot, and when a heating element is also set at the bottom of the inner pot, can realize the simultaneous heating of the inner pot by multiple heat sources. This can fully heat the food in the inner pot, improve heating efficiency, enhance the uniformity of heating of the food, and thus improve the taste of the food. The heat insulation not only reduces the heat radiated from the infrared heating element to the pot body, thereby reducing the probability of heat deformation of the pot body and extending its service life, but also prevents the pot body from getting too hot and burning your hands. Moreover, the infrared heating element is set inside the heat insulation, which is conducive to the heat being concentrated and radiated into the cooking cavity, thereby improving heat utilization, improving heating efficiency, and preventing heat radiation upward from causing overheating deformation of the plastic parts at the lid or damage to electronic components.

[0018] 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.

[0019] 2. In order to improve heating efficiency, the lower heating chamber is set in accordance with the cooking area of ​​the cooking chamber, so that the lower heating chamber can provide the heat required for cooking the food, with a high heat utilization rate. The lower heating chamber and the heating structure at the bottom of the inner pot provide heat at the same time, which can improve the uniformity of heating of the food, thereby improving the overall taste of the food and enhancing the quality of the food.

[0020] 3. In order to reduce heat transfer between the two chambers, the upper end of the heat insulation component abuts against the outer wall of the inner pot to divide the cavity into an independent lower heating chamber and an upper heat preservation chamber. That is, the lower heating chamber and the upper heat preservation chamber are not connected. This can reduce the heat transferred directly from the infrared heating element to the upper heat preservation chamber, which helps to reduce the heat reaching the lid and thus reduce the impact on the structure of the plastic parts or electronic devices at the lid.

[0021] 4. To improve heat utilization and reduce heat waste, a reflector is provided inside the lower heating cavity to cover the infrared heating element. The reflector is fixed to the heat insulation component by fasteners. The reflector 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.

[0022] Furthermore, to achieve modular design, the infrared heating element can be fixed to the reflector via clamps on the inner surface of the reflector. Thus, the infrared heating element, reflector, and heat insulation component form a single unit, becoming a modular structure. This facilitates transportation and prevents any missing parts during manufacturing. When in use, it is installed as a single component, resulting in fewer installation steps and higher installation efficiency. In addition, after the infrared heating element is clamped and fixed, it can prevent displacement, such as falling downwards, which would affect the heating effect of the inner pot side wall. It can also prevent the infrared heating element from falling and causing excessive heat at the bottom, which would lead to the food burning.

[0023] 5. The heat insulation component has a certain longitudinal height so that the lower heating cavity covers the cooking area of ​​the cooking cavity and reduces the heat received by the pot body. To facilitate the placement of the infrared heating element inside the heat insulation component, the heat insulation component can use a splicing structure. For example, the heat insulation component includes an upper heat insulation part and a lower heat insulation part, which are spliced ​​together vertically. This makes it easier to determine the position of the infrared heating element when installing it, avoiding the difficulty of directly inserting the infrared heating element into the heat insulation component, which would affect the installation efficiency and the accuracy of the installation position.

[0024] 6. The infrared heating element can be a ring-shaped tube. To facilitate the installation of the infrared heating element, a reflector covering the infrared heating element is provided in the lower heating cavity. The reflector includes a left reflector and a right reflector. The left reflector and the right reflector are connected by splicing in the horizontal direction. After the reflector is divided into two parts, the length of the left reflector and the right reflector is reduced, making it easier to handle. This allows the infrared heating element to be fixed to one of the reflectors first and then to the other, reducing installation difficulty and improving efficiency.

[0025] Furthermore, the reflector and the heat insulation component are provided with a connecting notch for the wiring of the infrared heating element to pass through. By setting the notch, conditions are provided for the infrared heating element to be electrically connected to the external structure, and side wiring can be realized to provide an optimized wiring method and prevent problems such as excessively long lines, wire compression, and wire tangling caused by improper wiring.

[0026] 7. To improve the uniformity of circumferential heating of the inner pot, the infrared heating element includes a tubular body and a wiring terminal at the end of the body. The infrared heating element is provided at least one. The body is arranged around the outer wall of the inner pot, and the ends of two adjacent bodies are overlapped to form an annular heating area on the outer side of the inner pot. That is, the infrared heating element can provide 360° circumferential heating of the inner pot so that the food in the circumferential direction is heated evenly, improving the overall heating consistency of the food and thus improving the overall taste of the food.

[0027] 8. To improve the heating effect of the inner pot, the heat insulation component includes a top wall and a side wall extending downward from the top wall. The top wall surrounds the inner pot, and the bottom end of the side wall abuts against the bottom of the pot body. A heating plate is provided at the bottom of the inner pot, and the top end of the heating plate is flush with the bottom end of the side wall. That is, the side wall of the heat insulation component has a certain longitudinal height, which is conducive to the heat of the lower heating chamber covering more of the axial area of ​​the inner pot, improving the uniformity of heating of the food in the axial direction. Moreover, the heat of the lower heating chamber and the heat of the heating plate are connected in the axial direction to jointly cover most of the axial area of ​​the inner pot, which is conducive to the food at the bottom and the upper layer being fully and evenly heated, thus improving the overall taste of the food.

[0043] like Figures 1 to 5As shown, this application provides a cooking appliance, including a pot body 10 and a lid. The pot body 10 is provided with an inner pot 11 having a cooking cavity and an infrared heating element 12. The infrared heating element 12 is used to radiate infrared rays into the cooking cavity. A cavity 13 is formed between the pot body 10 and the inner pot 11. A heat insulation element 14 is provided in the cavity 13. The heat insulation element 14 divides the cavity 13 into a lower heating cavity 131 and an upper heat preservation cavity 132. The infrared heating element 12 is disposed in the lower heating cavity 131.

[0044] Specifically, the infrared heating element 12 of this application can radiate infrared rays of multiple wavelengths into the cooking cavity during the cooking process. It has strong penetrability, can penetrate and heat food, and stimulate the aroma of food. For example, when the cooking appliance is a rice cooker, it can better stimulate the aroma of rice, thereby improving the user's appetite. The heating element of the infrared heating element 12 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.

[0045] like Figure 1 As shown, a gap is formed between the pot body 10 and the inner pot 11, which is the cavity 13. The heat insulation component 14 divides the space of the cavity 13 into two chambers. The lower heating chamber 131 provides conditions for the arrangement of the infrared heating element 12, which can increase the temperature rise rate of the side wall of the inner pot 11. 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 132 helps to maintain the temperature of the upper part of the inner pot 11. 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 11 from being too low, which would cause the rising steam to easily form condensation and affect the rate of water evaporation. In other words, it helps to accelerate the evaporation of water in the inner pot 11 and improve cooking efficiency. The heat insulation component 14 not only reduces the heat radiated from the infrared heating element 12 to the pot body 10, thereby reducing the probability of thermal deformation of the pot body 10 and extending its service life, but also prevents the pot body 10 from getting too hot to touch. Furthermore, the infrared heating element 12 is located inside the heat insulation component 14, which is conducive to the heat being concentrated and radiated into the cooking cavity, thereby improving heat utilization and heating efficiency, and preventing the upward radiation of heat from causing overheating deformation of the plastic parts at the lid or damage to the electronic components.

[0046] Both the infrared heating element 12 and the heat insulation element 14 are arranged around the inner pot 11. The top of the heat insulation element 14 can block the gap between the pot body 10 and the inner pot 11, thus preventing the heat from the infrared heating element 12 from being directly transferred upwards and affecting the upper structure. The infrared heating element 12 radiates infrared rays into the cooking cavity, causing the side wall of the inner pot 11 to heat up, which can improve the temperature of the upper side wall of the inner pot 11. In addition, the heat preservation effect of the upper heat preservation cavity 132 can prevent the temperature of this part of the side wall from dropping too quickly and affecting the evaporation rate of water, which is beneficial to improving the cooking effect of the upper food. The bottom of the heat insulation element 14 can be closed (closed means sealing the gap between the pot body 10 and the inner pot 11) or open, which is not limited in this application.

[0047] In a preferred embodiment, the bottom of the inner pot 11 is provided with a bottom heating element 15. When the bottom heating element 15 and the infrared heating element 12 work simultaneously, multiple heat sources can heat the inner pot 11 at the same time, which can fully heat the food in the inner pot 11, improve heating efficiency, enhance the uniformity of heating of the food, and thus improve the taste of the food.

[0048] It should be noted that, in one embodiment, an installation gap is formed between the top of the heat insulation member 14 and the outer wall of the inner pot 11, that is, the lower heating chamber 131 and the upper heat preservation chamber 132 are not completely independent, and there is a connection between the two chambers. However, since the width of the installation gap is no more than 5mm, the heat transfer between the two chambers is very small, so it does not affect the heating effect of the lower heating chamber 131 on the side of the inner pot 11.

[0049] In another embodiment, the upper end of the heat insulation member 14 abuts against the outer wall of the inner pot 11 to divide the cavity into an independent lower heating cavity 131 and an upper heat preservation cavity 132. That is, the lower heating cavity 131 and the upper heat preservation cavity 132 are not connected, which can reduce the heat transferred directly from the infrared heating element 12 to the upper heat preservation cavity 132, which helps to reduce the heat reaching the cover, thereby reducing the impact on the structure of the plastic parts or electronic devices on the cover.

[0050] As a preferred embodiment, the lower heating cavity 131 is set to correspond to the cooking area of ​​the cooking cavity, which enables the lower heating cavity 131 to provide the heat required for cooking the food, with a high heat utilization rate. When the lower heating cavity 131 and the bottom heating element 15 at the bottom of the inner pot 11 provide heat at the same time, the uniformity of heating of the food can be improved, thereby improving the overall taste of the food and enhancing the quality of the food.

[0051] like Figure 1 As shown, the cooking area of ​​the cooking cavity covers, for example, the area below the middle height of the inner pot 11. The rice-water mixture is usually in this area. By radiating infrared rays to the cooking area through the lower heating cavity 131, all ingredients can be fully heated, ensuring the consistency of the ingredients' taste.

[0052] In a preferred embodiment, the surface of the heat insulation member 14 facing the infrared heating member 12 is provided with an infrared reflective coating.

[0053] The infrared reflective coating can reflect the heat radiated by the infrared heating element 12 toward the heat insulation element 14 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, thereby helping to lower the temperature of the pot body 10. By setting the infrared reflective coating, the separate reflective structure can be omitted, which helps to simplify the structural configuration and reduce costs.

[0054] In this embodiment, the inner surface of the heat insulation member 14 is also provided with a clamping member for fixing the infrared heating member 12.

[0055] In a preferred embodiment, the lower heating cavity 131 is provided with a reflector 16 covering the infrared heating element 12, and the reflector 16 is fixed to the heat insulation element 14 by fasteners.

[0056] like Figure 2 As shown, the reflector 16 can reflect the heat radiated by the infrared heating element 12 towards the heat insulation element 14 back 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. Using the reflector 16 to cover the infrared heating element 12 helps to concentrate heat and has a good heat reflection effect. Furthermore, the reflector 16 and the heat insulation element 14 can form a double-layer heat insulation structure, which can improve the heat insulation effect. The two are used as a single unit, simplifying the installation process. Specifically, the reflector 16 can be fixed to the heat insulation element 14 with screws, ensuring a secure installation and reliable use.

[0057] In one embodiment, the inner surface of the reflector 16 is provided with a clamping member 17, and the infrared heating element 12 is fixed to the reflector 16 by the clamping member 17.

[0058] Thus, the infrared heating element 12, reflector 16, and heat insulation element 14 are integrated into a single unit, forming a modular structure. This facilitates transportation and prevents any missing parts during manufacturing. When in use, they are installed as a single unit, resulting in fewer installation steps and higher installation efficiency. Furthermore, once the infrared heating element 12 is clamped and fixed, it can prevent displacement, such as falling downwards, from affecting the heating effect of the inner pot 11 side wall 145. It can also prevent excessive heat at the bottom caused by the infrared heating element 12 falling, which could lead to food burning.

[0059] In other implementations, such as Figure 3 As shown, the lower heating cavity 131 is provided with a reflector 16 covering the infrared heating element 12. The reflector 16 and the heat insulation element 14 are independent of each other and can be fixed to the pot body 10 respectively.

[0060] In a preferred embodiment, the heat insulation member 14 includes an upper heat insulation part 141 and a lower heat insulation part 142, which are vertically spliced ​​together.

[0061] Because the heat insulation component 14 has a certain vertical height so that the lower heating cavity 131 covers the cooking area of ​​the cooking cavity and reduces the heat received by the pot body 10, the heat insulation component 14 can use a splicing structure to facilitate the placement of the infrared heating element 12 inside the heat insulation component 14. For example, the heat insulation component 14 includes an upper heat insulation part 141 and a lower heat insulation part 142, which are vertically spliced ​​together. This makes it easier to determine the position of the infrared heating element 12 when installing it, avoiding the difficulty of directly inserting the infrared heating element 12 into the heat insulation component 14, which would affect the installation efficiency and the accuracy of the installation position. Specifically, the upper heat insulation part 141 and the lower heat insulation part 142 can be spliced ​​together using a snap-fit ​​structure.

[0062] In a preferred embodiment, the lower heating cavity 131 is provided with a reflector 16 that covers the infrared heating element 12. The reflector 16 includes a left reflector 161 and a right reflector 162, which are connected by splicing in the horizontal direction.

[0063] The infrared heating element 12 can be a ring-shaped tube. To facilitate the installation of the infrared heating element 12, the reflector 16 is divided into two parts, and the lengths of the left reflector 161 and the right reflector 162 are reduced, making it easier to handle. This allows the infrared heating element 12 to be fixed to one of the reflectors first and then to the other, reducing installation difficulty and improving efficiency.

[0064] like Figure 4 As shown, in a preferred embodiment, at least one clamping member 17 is provided on the inner surface of both the left reflector 161 and the right reflector 162, which can clamp the tube body of the infrared heating element 12, making operation simple. The left reflector 161 and the right reflector 162 can be spliced ​​together by a snap-fit ​​structure. The heat insulation member 14 includes an upper heat insulation member 141 and a lower heat insulation member 142, which are spliced ​​together vertically. Furthermore, a splicing screw post 143 is provided at the joint of the upper heat insulation member 141 and the lower heat insulation member 142, and the reflector 16 is provided with screw holes 163. By using screws to fix the reflector 16 to the heat insulation member 14, the splicing firmness of the upper heat insulation member 141 and the lower heat insulation member 142 can be strengthened, which is beneficial to improving the stability of the overall structure.

[0065] Furthermore, the reflector 16 and the heat insulation element 14 are provided with a communicating notch 18 for the wiring of the infrared heating element 12 to pass through.

[0066] like Figure 4 and Figure 5As shown, by setting the notch 18, conditions are provided for the infrared heating element 12 to be electrically connected to the external structure, which can realize the side wiring, so as to provide an optimized wiring method and prevent problems such as excessively long lines, wire compression, and wire tangling caused by improper wiring.

[0067] exist Figure 4 In the embodiments, the infrared heating element 12 is an annular structure with an opening on one side. In order to make the heat of the infrared heating element 12 evenly distributed in the circumference, the two ends of the infrared heating element 12 can be overlapped, or a spiral infrared heating element 12 can be used so that the inner pot 11 can be heated in all directions of 360°, thereby improving heating efficiency and enhancing heating uniformity.

[0068] In a preferred embodiment, the infrared heating element 12 includes a tubular body and a wiring terminal at the end of the body. The infrared heating element 12 is provided with at least one, the body is arranged around the outer wall of the inner pot 11, and the ends of two adjacent bodies are overlapped to form an annular heating zone on the outer side of the inner pot 11.

[0069] Specifically, when there is one infrared heating element 12, the two ends of the main body overlap, either radially or vertically. In either case, it provides 360° circumferential heating to the inner pot 11, ensuring even heating of the food in the circumferential direction and improving the overall consistency of heating, thus enhancing the overall taste. Alternatively, when there are two infrared heating elements 12, both main bodies extend in an arc shape, together surrounding the inner pot 11. The ends of adjacent main bodies overlap, either radially or vertically. In either case, it provides 360° circumferential heating to the inner pot 11, ensuring even heating of the food in the circumferential direction and enhancing the overall consistency of heating, thus enhancing the overall taste.

[0070] In a preferred embodiment, the heat insulation member 14 includes a top wall 144 and a side wall 145 extending downward from the top wall 144. The top wall 144 is arranged around the inner pot 11, and the bottom end of the side wall 145 abuts against the bottom of the pot body 10. The bottom of the inner pot 11 is provided with a bottom heating element 15, which is a heating plate. The top end of the heating plate is flush with the bottom end of the side wall 145.

[0071] like Figure 1As shown, the sidewall 145 of the heat insulation component 14 has a certain longitudinal height, which is beneficial for the heat from the lower heating chamber 131 to cover more of the axial area of ​​the inner pot 11, improving the uniformity of heating of the food along the axial direction. Moreover, the heat from the lower heating chamber 131 and the heat from the heating plate are connected axially to cover most of the axial area of ​​the inner pot 11, which is beneficial for the bottom and upper layers of food to be fully and evenly heated, thus improving the overall taste of the food. Specifically, the heating plate can heat the bottom of the inner pot 11 and the sidewall near the bottom, and the lower heating chamber 131 can heat at least the lower sidewall 145 of the inner pot 11. When cooking rice, the rice in the upper part of the inner pot 11 heats up at a rate close to that of the rice at the bottom, so that the rice in the entire inner pot 11 absorbs water, gelatinizes, and cooks almost simultaneously, thus achieving uniform heating and ensuring that the rice in all positions has a consistent taste, which can improve the user experience.
