Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a cooking device. Background Technology

[0002] With the continuous development of science and technology, cooking appliances with baking functions, such as ovens, have become common household appliances in people's daily lives. In the current technology, these cooking appliances usually use heating elements to directly heat the heating cavity. In this way, the heating elements are easily contaminated by oil droplets splashed inside the heating cavity, making them difficult to clean. In addition, some of the heat from the heating elements is directly radiated to the inner wall of the heating cavity, which easily leads to energy waste. Summary of the Invention

[0003] This application provides a cooking device that can improve the cooking speed and energy utilization rate of the cooking device, and improve the ease of cleaning the cooking device.

[0004] To solve the above-mentioned technical problems, this application provides a cooking device, which includes a first housing and a heating component. The first housing is provided with a heating cavity. The heating component includes a second housing with a receiving cavity and a first radiating element disposed in the receiving cavity. The second housing is provided with an energy blocking part and an energy focusing and emitting part. The side of the energy blocking part facing the first radiating element forms a reflective surface. The radiant energy emitted by the first radiating element to the energy blocking part is reflected by the reflective surface to the energy focusing and emitting part, so as to radiate from the energy focusing and emitting part to the food heating area in the heating cavity.

[0005] The beneficial effects of this application are as follows: The cooking device of this application includes a first housing and a heating element. The first housing is provided with a heating cavity. The heating element includes a second housing with a receiving cavity and a first radiating element disposed in the receiving cavity. The second housing is provided with an energy blocking part and an energy focusing and emitting part. The side of the energy blocking part facing the first radiating element forms a reflective surface. The radiant energy emitted by the first radiating element to the energy blocking part is reflected by the reflective surface to the energy focusing and emitting part, so as to radiate from the energy focusing and emitting part to the food heating area in the heating cavity. The energy-concentrating output section can gather the divergent radiant energy emitted by the first radiating element, improving the uniformity of heat radiation from the heating element. The energy-concentrating output section allows the gathered radiant energy to be radiated to the food heating zone within the heating cavity, facilitating directional energy concentration, improving the heating effect and speed of the food in the heating zone, and reducing heat loss caused by the radiant energy emitted by the first radiating element hitting the sidewalls of the heating cavity, thus improving the energy conversion efficiency of the cooking equipment. The reflective surface of the energy-blocking section reflects the radiant energy directed towards it back to the energy-concentrating output section, reducing heat loss caused by the radiant energy emitted by the first radiating element hitting the inner wall of the second housing, increasing the radiation amount of the energy-concentrating output section, and thus increasing the heat radiation intensity of the heating element, improving the energy utilization rate of the cooking equipment. Furthermore, the first radiating element is located within the accommodating cavity, reducing the risk of oil droplets or high-temperature steam splashing from the heating cavity contaminating the first radiating element, improving the ease of cleaning the cooking equipment.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] This application first proposes a cooking device, such as Figures 1 to 7As shown. The cooking device includes a first housing 10 and a heating element 20. The first housing 10 is provided with a heating cavity 101. The heating element 20 includes a second housing 21 provided with a receiving cavity 201 and a first radiating element 22 disposed in the receiving cavity 201. The second housing 21 is provided with an energy blocking part 211 and an energy focusing and emitting part 212. The side of the energy blocking part 211 facing the first radiating element 22 forms a reflective surface. The radiant energy emitted by the first radiating element 22 to the energy blocking part 211 is reflected by the reflective surface to the energy focusing and emitting part 212, so as to radiate from the energy focusing and emitting part 212 to the food heating area in the heating cavity 101.

[0019] The heating chamber 101 is used to heat food, and the food heating area inside the heating chamber 101 can hold food for heating. The first radiating element 22 can emit radiant energy in the accommodating cavity 201. Part of the emitted radiant energy is directly directed to the energy-concentrating output part 212, and part is directed to the energy-blocking part 211. The reflective surface of the energy-blocking part 211 facing the first radiating element 22 can reflect the radiant energy directed to the energy-blocking part 211 back to the energy-concentrating output part 212. The radiant energy reaching the energy-concentrating output part 212 is focused through the energy-concentrating output part 212 and then radiates to the food heating area inside the heating chamber 101.

[0020] In the above configuration, the energy-concentrating output section 212 can concentrate the divergent radiant energy emitted by the first radiating element 22, improving the uniformity of heat radiation from the heating element 20; the energy-concentrating output section 212 can radiate the concentrated radiant energy to the food heating zone within the heating cavity 101, facilitating directional energy concentration, improving the food heating effect and heating speed within the heating cavity 101, and reducing heat loss caused by the radiant energy emitted by the first radiating element 22 irradiating the sidewalls of the heating cavity 101, thus improving the energy conversion efficiency of the cooking equipment; the energy-blocking section 211... The reflective surface can reflect the radiant energy directed towards the energy blocking part 211 to the energy concentrating and emitting part 212, which can reduce heat loss caused by the radiant energy emitted from the first radiating element 22 irradiating the inner wall of the second housing 21, and increase the radiation amount of the energy concentrating and emitting part 212. Therefore, it can increase the heat radiation intensity of the heating element 20 and improve the energy utilization rate of the cooking equipment. Furthermore, the first radiating element 22 is disposed in the accommodating cavity 201, which can reduce the risk of oil droplets or high-temperature steam splashing in the heating cavity 101 contaminating the first radiating element 22 and improve the ease of cleaning the cooking equipment.

[0021] In one application scenario, the side of the second housing 21 closest to the food heating zone can be set as the energy-concentrating and energy-generating part 212, and the other areas can be set as energy-blocking parts 211. The side of the energy-blocking part 211 facing the first radiating element 22 forms a reflective surface to improve the energy-concentrating and energy-generating effect.

[0022] See Figures 6 to 7 , Figure 6and Figure 7 Simulation diagrams show the energy-concentrating effect of the radiating component in two different states, where the position of the first radiating element 22 within the accommodating cavity 201 differs. Since the position of the first radiating element 22 within the accommodating cavity 201 determines its relative position to the energy-concentrating output section 212 and the reflecting surface, the path of the radiant energy emitted by the first radiating element 22—whether directly incident or indirectly incident on the energy-concentrating output section 212 after reflection—varies depending on its position within the accommodating cavity 201. This results in different focusing effects of the energy-concentrating output section 212 on the incident radiant energy. In other words, the radiation range of the radiant energy emitted from the energy-concentrating output section 212 changes depending on its position within the accommodating cavity 201. Therefore, the position of the first radiating element 22 within the accommodating cavity 201 can be adjusted according to the size requirements of the food heating zone within the heating cavity 101, so that the radiant energy emitted from the energy-concentrating output section 212 is more concentrated in the food heating zone.

[0023] In some embodiments, the energy blocking part 211 is provided with a plurality of mounting positions, and the first radiating element 22 is selectively disposed on one mounting position to adjust the relative position between the first radiating element 22 and the reflecting surface.

[0024] This arrangement increases the ease of adjusting the relative position between the first radiating element 22 and the reflective surface. By changing the mounting position of the first radiating element 22, the radiation path of the radiant energy incident on the energy-concentrating and emitting section 212 can be altered, thereby changing the radiation range of the radiant energy emitted from the energy-concentrating and emitting section 212. Therefore, the position of the first radiating element 22 within the receiving cavity 201 can be adjusted according to the size requirements of the food heating zone within the heating cavity 101 or the size of the heating cavity 101 itself. This arrangement facilitates the selection of different mounting positions for different product sizes, improving assembly convenience.

[0025] In some embodiments, the first radiating element 22 includes a carbon fiber heating element or a metal heating element. Carbon fiber heating elements typically have higher electrothermal conversion efficiency, longer service life, and better environmental performance; metal heating elements, on the other hand, have advantages in terms of cost, mechanical strength, and processing flexibility.

[0026] In some embodiments, the first radiating element 22 includes a resistance wire heating tube, a graphite heating tube, or an infrared heating element. The heat from the first radiating element 22 can be transferred to the food heating zone inside the heating cavity 101 through convection and radiation heat transfer. When the first radiating element 22 is an infrared heating element, infrared radiation heating can be used to bake food. Infrared radiation has strong penetrating power and can heat the surface and interior of the food simultaneously, resulting in high energy utilization. Graphite heating tubes have good thermal stability, facilitating uniform heating. Resistance wire heating tubes facilitate rapid heating.

[0027] In some embodiments, the first radiating element 22 includes a U-shaped heating tube, which can improve the uniformity of the distribution of radiant energy emitted from the energy-concentrating output section 212 within the heating cavity 101, thereby improving the uniformity of cooking heating.

[0028] In some embodiments, the heating component 20 is movably connected to the inner wall of the heating cavity 101.

[0029] The heating element 20 is movably connected to the inner wall of the heating cavity 101, which allows the user to adjust the position of the heating element 20 in the heating cavity 101 according to the user's needs (e.g., control the heating element 20 to rotate at an angle, raise or lower its position, etc.). Therefore, it is easy to adjust the radiation range of the radiant energy emitted from the energy-concentrating and energy-emitting part 212 in the heating cavity 101. Thus, it is possible to control the radiation range to cover a specific area of ​​the food heating zone, such as covering part of the food to be heated in the food heating zone, so as to achieve directional heating. Therefore, it can improve the flexibility of cooking, improve the cooking effect and the user experience.

[0030] In some embodiments, the cooking device further includes a first driving element and a control component. The first driving element, such as a stepper motor, is used to drive the heating element 20 to move. The position adjustment of the heating element 20 can be achieved using the first driving element and the control component. This adjustment method enables automatic adjustment without the need for manual adjustment of the heating element 20. Therefore, it is convenient to control the position of the heating element 20 based on the cooking effect of the food during the cooking process. It also helps to reduce the risk of burns due to excessively high temperature inside the cooking cavity or excessively high temperature of the heating element 20 when adjusting its position, thus improving the user experience.

[0031] In some embodiments, see Figure 4 The energy blocking part 211 forms a receiving cavity 201 and an opening communicating with the receiving cavity 201. A Fresnel lens is placed over the opening as the aforementioned energy focusing and output part 212.

[0032] It should be noted that the installation method of the Fresnel lens is not limited. For example, the Fresnel lens can be fixed to the opening by adhesive bonding or by other methods such as snap-fit.

[0033] In one application scenario, the energy blocking part 211 and the energy focusing and outputting part 212 enclose and form a receiving cavity 201. For example, the energy blocking part 211 forms the receiving cavity 201, and the energy focusing and outputting part 212 covers the opening of the receiving cavity 201. The energy focusing and outputting part 212 is composed of a Fresnel lens.

[0034] Fresnel lenses are made based on the Fresnel principle, capable of converging divergent radiant energy emitted from an energy radiation source (such as the first radiating element 22), for example, converging divergent light emitted by a light source into collimated light or a focused beam. Fresnel lenses use a series of concentric grooves or zones instead of the curved surface of traditional energy lenses. Each zone is equivalent to a tiny refractive element, and they work together to converge the incident radiant energy. Therefore, compared to traditional convex lenses, Fresnel lenses have smaller dimensions in terms of external profile, a thinner structure, and can be manufactured using simple processes. Thus, Fresnel lenses not only retain the energy-converging effect of convex lenses but also significantly reduce lens thickness.

[0035] Therefore, by using a Fresnel lens to form an energy-concentrating output section 212, the divergent energy radiated by the first radiator 22 can be concentrated at the location of the food to be heated, which can achieve the effect of energy concentration and superposition, and reduce the heat radiation of the first radiator 22 to the side wall of the heating cavity 101.

[0036] In some embodiments, the energy-concentrating and outputting part 212 is made of quartz glass, which has a high thermal radiation transmittance. Therefore, most of the energy radiated by the first radiating element 22 can be directly transferred to the food itself through the quartz glass. At the same time, the surface of the quartz glass is smooth, and if oil stains and salt spray accidentally splash onto the surface of the quartz glass during the cooking process, the stains can be removed by simple wiping, which can improve the convenience of cleaning and the hygiene of the heating chamber 101. Furthermore, the quartz glass has good high temperature resistance, and its surface will not discolor or deform due to high temperatures, improving the user experience.

[0037] In other embodiments (not shown), a plano-convex lens can also be used to form the energy-concentrating and energy-generating section.

[0038] In some embodiments, see Figures 1 to 3 The heating component 20 includes a plurality of first radiating elements 22, and the second housing 21 is provided with a plurality of energy-concentrating and energy-emitting parts 212. The energy-blocking part 211 forms a plurality of reflectors 213 spaced apart along the first direction x and a connecting part 214 connecting two adjacent reflectors 213. The energy-concentrating and energy-emitting parts 212 are sealed and covered on the openings of the corresponding reflectors 213, so that the second housing 21 forms a plurality of sealed accommodating cavities 201 spaced apart along the first direction x. At least one first radiating element 22 is provided in the accommodating cavity 201.

[0039] The energy-concentrating output section 212 is sealed at the opening of the corresponding reflector 213, facilitating the sealing of the receiving cavity 201. This allows the radiated energy emitted by the first radiating element 22 to be directly incident on or indirectly reflected to the energy-concentrating output section 212 as much as possible, thereby reducing the risk of wasted heat radiated by the first radiating element 22 and increasing the energy radiated by the energy-concentrating output section 212. Furthermore, this arrangement ensures that the first radiating element 22 is sealed within the receiving cavity 201, reducing the risk of contamination by high-temperature steam or oil droplets. Multiple sealed receiving cavities 201, multiple first radiating elements 22, and multiple... The energy-concentrating and energy-emitting part 212 facilitates increasing the radiation range of the radiation component 20 to the food heating zone within the heating chamber 101, thereby improving the heating effect of the radiation component 20 on the food heating zone within the heating chamber 101. The connection part 214 facilitates connecting multiple reflectors 213, allowing multiple reflectors 213 to be integrated, which improves the assembly convenience of the overall structure. The multiple reflectors 213 are spaced apart along the first direction x, which facilitates the multiple first radiating elements 22 to be spaced apart along the first direction x, reducing interference between the multiple first radiating elements 22 and improving the heating uniformity of the radiation component 20 on the food heating zone.

[0040] In some embodiments, the energy-concentrating output part 212 and the reflector 213 are sealed together by welding or gluing to form a sealed accommodating cavity 201. The first radiating element 22 is disposed in the accommodating cavity 201. The sealed accommodating cavity 201 can also be filled with an inert gas such as helium or the accommodating cavity 201 can be evacuated.

[0041] In some embodiments, the heating element 20 is disposed inside the heating cavity 101 and located on the top wall of the heating cavity 101, so as to directly radiate heat to the food heating area; in other embodiments (not shown), the heating element 20 is disposed on the first housing 10 as part of the top wall of the heating cavity 101, and the radiant energy emitted by its corresponding energy-concentrating and energy-emitting part 212 radiates toward the food heating area.

[0042] In other embodiments (not shown), the cooking device includes multiple heating elements, each disposed at a different position within the heating chamber. The radiant energy emitted from the energy-concentrating output section corresponding to each heating element radiates towards the food heating zone within the heating chamber. This arrangement facilitates heating the food heating zone from multiple directions, improving the uniformity and rate of food heating. Combinations of multiple heating elements at different positions can be selected based on baking requirements.

[0043] For example, in some embodiments, multiple heating elements 20 can be arranged around the top of the heating cavity 101 to form a U-shaped structure. Each heating element 20 can be configured to include only a first radiating element 22, a corresponding reflector 213, and an energy-concentrating output part 212. This arrangement facilitates heating of the food heating zone from multiple directions at the top and can improve heating uniformity.

[0044] For example, in other embodiments, the heating element 20 may be located at the bottom and side wall of the heating chamber 101, or it may be set separately at the bottom of the heating chamber 101, or it may be set separately on multiple side walls of the heating chamber 101, and the radiation energy emitted by its corresponding energy-concentrating and energy-emitting part 212 may radiate toward the food heating area.

[0045] In some embodiments, the inner surface of the reflector 213 is a parabolic surface.

[0046] The inner surface of the reflector 213 serves as a reflective surface to reflect radiated energy to the energy-concentrating output section 212. The parabolic shape facilitates the placement of the energy-concentrating output section 212 over the opening of the reflector 213, ensuring accurate reflection of radiated energy to the energy-concentrating output section 212 and improving the energy-concentrating effect of the second shell 21.

[0047] In some embodiments, see Figure 3 , Figure 4 As shown, the reflector 213 forms a parabolic cylindrical cover wall. The reflector 213 also forms two ends arranged along the generatrix a of the parabolic cylindrical surface. The two ends are respectively located at both ends of the parabolic cylindrical cover wall, and together with the parabolic cylindrical cover wall, they form an opening of the reflector 213. The energy-concentrating and energy-emitting part 212 is sealed at the opening to form a sealed accommodating cavity 201 for accommodating the first radiating element 22.

[0048] Specifically, a surface formed by a straight line moving parallel to a fixed curve is called a cylindrical surface. The moving straight line is called the generatrix a of the cylindrical surface, and the fixed curve is called the directrix of the cylindrical surface. When the directrix is ​​a circle, the resulting cylindrical surface is called a circular cylindrical surface, and when the directrix is ​​a parabola, the resulting cylindrical surface is called a parabolic cylindrical surface. In some embodiments, when the energy blocking part 211 includes multiple reflectors 213, the direction of the generatrix a of the parabolic cylindrical surface corresponding to the reflector 213 is perpendicular to the first direction x. The connecting part 214 connecting the multiple reflectors 213 is connected to the reflectors 213 at both ends of the parabolic cylindrical surface arranged along the first direction x.

[0049] In some embodiments, the first radiating element 22 may be movably or fixedly connected to the two ends, which facilitates setting the position of the first radiating element 22 in the accommodating cavity 201, thereby facilitating the adjustment of the focusing effect of the energy-concentrating and energy-emitting part 212 on the radiating energy emitted by the first radiating element 22, and facilitating the setting of the radiation range of the radiating energy emitted from the energy-concentrating and energy-emitting part 212.

[0050] In some embodiments, reflective surfaces are also provided on the side of the reflector 213 near the first radiator 22 at both ends to reflect radiated energy to the energy-concentrating output section 212, thereby improving the energy-concentrating effect of the radiating assembly 20; in other embodiments, only the parabolic cylindrical cover wall of the reflector 213 may be provided as a reflective surface.

[0051] In some embodiments, the reflector 213 forms a parabolic cylindrical cover wall. The two ends of the cover wall, arranged along the generatrix a of the parabolic cylinder, are respectively sealed to the inner wall of the heating cavity 101, forming a receiving cavity 201 and an opening communicating with the receiving cavity 201. The first radiating element 22 is disposed within the receiving cavity 201 and is movably or fixedly connected to the inner wall of the heating cavity 101. The energy-concentrating and emitting part 212 covers the opening and is sealed to the cover wall and the inner wall of the heating cavity 101, thereby sealing the receiving cavity 201. This arrangement directly utilizes the inner wall of the heating cavity 101, the energy-concentrating and emitting part 212, and the reflector 213 to jointly form a sealed receiving cavity 201, reducing space occupation and facilitating the fixing of the position of the first radiating element 22 within the receiving cavity 201.

[0052] In other embodiments, the reflector 213 forms an arc-shaped cover wall corresponding to a right cylindrical surface or an arc-shaped cover wall corresponding to an elliptical cylindrical surface. In some embodiments, when the reflector 213 further includes two ends, the two ends can be arranged at both ends of the arc-shaped cover wall along the generatrix a of the corresponding right cylindrical surface or along the generatrix a of the elliptical cylindrical surface, similar to the above embodiments; in some embodiments, when the energy blocking part 211 includes multiple reflectors 213, the connecting part 214 connecting the reflectors 213 can be arranged at both ends of the arc-shaped cover wall along the first direction x, similar to the above embodiments.

[0053] In some embodiments, the reflector 213 is a mirror reflector (e.g., mirror aluminum, mirror stainless steel, etc.). This configuration facilitates improved reflection of radiated energy by the reflector 213.

[0054] In some applications, reflectors 213 can be manufactured through processing methods such as polishing, coating, and rolling.

[0055] In some embodiments, the reflector 213 has a multi-layer structure, including a heat-resistant insulation layer, a reflective layer, and a protective layer. The heat-resistant insulation layer is located on the side of the reflector 213 away from the accommodating cavity 201. The heat-resistant insulation layer includes silica aerogel or acrylic pressure-sensitive adhesive, etc., and has good high-temperature resistance, heat insulation, corrosion resistance, and non-toxicity, and is easy to clean. The protective layer is disposed on the side of the reflective layer close to the first radiating element 22, and is used to protect the reflective layer of the reflector 213, improve its high-temperature resistance and other properties, and improve the reliability of the reflector 213.

[0056] In some embodiments, the reflective layer may also be constructed by using a reflective coating method, which involves adding metals and metal oxides with high reflectivity in the visible and infrared bands to the reflector 213, such as aluminum, silver, chromium, gold, etc.

[0057] In some embodiments, the cooking device further includes a camera component and a control component. The camera component is used to acquire cooking information of the food to be cooked placed in the food heating zone. The control component is connected to the camera component and the second housing 21 respectively, and controls the movement of the heating component 20 relative to the inner wall of the heating cavity 101 based on the cooking information, so as to adjust the relative positional relationship between the energy-concentrating and energy-emitting part 212 and the food heating zone.

[0058] In one application scenario, the camera component includes a built-in camera that can automatically correct the angle of the heating component 20 and adjust the orientation of the energy-concentrating output section 212 based on the position and baking status of the food observed by the built-in camera (i.e., the cooking information of the food to be cooked). This ensures that the radiation range of the radiant energy emitted from the energy-concentrating output section 212 covers a specific heating area.

[0059] The above settings can control the heating element 20 to change displacement or angle based on cooking information, which can improve cooking flexibility, enhance the adaptability of cooking equipment to multiple scenarios, and improve cooking results.

[0060] In some embodiments, the working time and radiation power of the first radiator 22 can be adjusted based on the cooking information of the food to be cooked, so as to further improve the control accuracy and flexibility of the cooking process and improve the cooking effect.

[0061] In some embodiments, the control component controls the relative movement of the first radiating element 22 and the second housing 21 based on cooking information to adjust the relative position between the first radiating element 22 and the second housing 21.

[0062] For example, in some embodiments, the second housing 21 is movably connected to the inner wall of the heating cavity 101, and the first radiating element 22 is fixedly connected to the inner wall of the heating cavity 101, so that by adjusting the position of the second housing 21, the first radiating element 22 and the reflective surface can move relative to each other; in other embodiments, the second housing 21 is fixedly connected to the inner wall of the heating cavity 101, and the first radiating element 22 is movably connected to the inner wall of the heating cavity 101 (or the first radiating element 22 is movably connected to the two ends of the reflector 213 mentioned above), so that by adjusting the position of the first radiating element 22, the first radiating element 22 and the second housing 21 can move relative to each other.

[0063] The change in the relative position between the first radiating element 22 and the second housing 21 alters the radiation path of the radiant energy emitted from the first radiating element 22—whether it directly enters the energy-concentrating output section 212 or is reflected by the energy-blocking section 211 and then indirectly enters it. This results in different focusing effects of the energy-concentrating output section 212 on the incident radiant energy; that is, the radiation range of the radiant energy emitted from the energy-concentrating output section 212 changes with the change in the relative position between the first radiating element 22 and the second housing 21. Therefore, the relative position between the first radiating element 22 and the second housing 21 can be adjusted according to the size of the space within the heating cavity 101 where the food to be cooked or the area to be heated, so that the radiant energy emitted from the energy-concentrating output section 212 is more concentrated on the food to be cooked or the area to be heated. This arrangement further improves cooking flexibility and cooking results.

[0064] In some embodiments, the cooking device further includes a second driving member connected to the second housing 21 or the first radiating member 22. The second driving member is controlled by the cooking information control component to drive the first radiating member 22 or the second housing 21 to move or rotate, so as to adjust the relative positional relationship between the first radiating member 22 and the second housing 21, thereby achieving automatic positional adjustment, improving safety and enhancing the user experience.

[0065] In some embodiments, the heating element 20 is disposed on the top wall of the heating chamber 101, and the cooking device also includes an auxiliary heating element 30, which is detachably disposed in the heating chamber 101.

[0066] Due to the position of the heating element 20 and the air density, the temperature inside the heating cavity 101 typically decreases from top to bottom. Therefore, during cooking, food may experience uneven heating, moisture loss, and surface burning, affecting food quality. This embodiment addresses these issues by adding an auxiliary heating element 30.

[0067] In some embodiments, the auxiliary heating element 30 can be placed at the bottom of the food to support the food. The auxiliary heating element 30 can provide contact heating to the food and can also be used as a detachable baking pan.

[0068] In some embodiments, the auxiliary heating element 30 consists of a heat-conducting section 32 and an insulating section 31.

[0069] The heat-conducting section 32 is located in the middle of the auxiliary heating element 30. In one application scenario, the heat-conducting section 32 is equipped with a second radiating element 33 (e.g., a heating resistor) and a heat-conducting plate. The second radiating element 33 can be disposed within the heat-conducting plate, which includes a flat surface with good thermal conductivity for placing food and allowing direct contact with the food. The good heat generation, easy cleaning, and corrosion resistance of the heat-conducting section 32 enable contact heating of the food. The insulating section 31 is a non-conductive structural plate that can be disposed on the outer periphery of the heat-conducting plate, facilitating user access to the auxiliary heating element 30.

[0070] In some embodiments, the auxiliary heating element 30 includes a plurality of second radiating elements 33 disposed in different areas within the heat-conducting plate. The plurality of second radiating elements 33 can simultaneously or at different times provide auxiliary heating to the food. The provision of multiple second radiating elements 33 not only increases the heating uniformity of the auxiliary heating element 30, but also allows for the selection of different second radiating elements 33 to operate according to the size of the food or the location to be heated, thereby improving cooking flexibility and cooking results.

[0071] In some embodiments, a guide rail 40 may also be provided inside the heating cavity 101. When using the auxiliary heating element 30, the auxiliary heating element 30 is placed at a specific position inside the heating cavity 101 via the guide rail 40.

[0072] In some embodiments, the inner wall of the heating cavity 101 is provided with a power supply interface, and the auxiliary heating element 30 is provided with a power connection terminal corresponding to the power supply interface; when the auxiliary heating element 30 is disposed in the heating cavity 101, the power supply interface is electrically connected to the power connection terminal to supply power to the auxiliary heating element 30.

[0073] The placement of electrical terminals and power supply interfaces facilitates the supply of power to the auxiliary heating element 30. In some embodiments, the auxiliary heating element 30 (e.g., the heating resistor in the heat-conducting section 32) has a plug-and-play function. For example, when food is placed on the heat-conducting section 32, the heat generated by the heating resistor is transferred to the heat-conducting section 32, and then the food is heated from the bottom through heat conduction. This arrangement can improve the problem of uneven heating of food and heat food through efficient heat conduction in direct contact, thereby improving the efficiency of heating food and saving heating time.

[0074] In some embodiments, see Figure 1 The first housing 10 forms a front sidewall and a rear sidewall that are arranged opposite to each other. The opening of the heating chamber is located on the front sidewall, and the front sidewall points to the rear sidewall in a direction parallel to the first direction x.

[0075] Specifically, since multiple reflectors 213 are arranged at intervals along the first direction x, it can be determined that, in this embodiment, the interval arrangement direction of the multiple reflectors 213 is parallel to the direction from the front sidewall to the rear sidewall, which facilitates assembly.

[0076] In other embodiments, the first housing 10 forms a front sidewall and a rear sidewall that are disposed opposite to each other, the opening of the heating cavity 101 is disposed on the front sidewall, the front sidewall points to the rear sidewall in a direction perpendicular to the first direction x, and the first radiating member 22 is movably connected to the rear sidewall.

[0077] Specifically, since multiple reflectors 213 are arranged at intervals along the first direction x, it can be determined that, in this embodiment, the interval arrangement direction of the multiple reflectors 213 is perpendicular to the direction from the front sidewall to the rear sidewall. In this way, multiple reflectors 213 can be fixedly connected to the rear sidewall, multiple first radiating elements 22 arranged along the first direction x can be movably connected to the rear sidewall, and a second driving element for driving the second housing 21 or the first radiating elements 22 to move can be provided on the rear sidewall of the first housing 10, and a first driving element for driving the entire heating assembly 20 to move can be provided on the rear sidewall of the first housing 10. Since the rear sidewall of a cooking device usually has more installation space reserved, setting the first and second driving elements on the rear sidewall in this way simplifies the overall structural design and facilitates assembly.

[0078] In some embodiments, the refractive index of the material of the energy-concentrating and energy-emitting section 212 ranges from 1.43 to 1.47; the ratio of the focal length of the lens of the energy-concentrating and energy-emitting section 212 to the focal length of the parabolic surface of the reflector 213 ranges from 5 to 15.

[0079] It should be noted that the above ratio refers to the ratio obtained by comparing the focal length of the lens of the energy-gathering and energy-emitting section 212 with the focal length of the parabolic surface of the reflector 213. For example, in some embodiments, when the focal length of the lens of the energy-gathering and energy-emitting section 212 is set to 10cm, the focal length of the parabolic surface of the reflector 213 can be set to be greater than or equal to 2 / 3cm and less than or equal to 2cm, such as 0.67cm, 0.68cm, 0.8cm, 0.9cm, 1cm, 1.5cm, or 2cm, etc.; as another example, in some embodiments, when the focal length of the lens of the energy-gathering and energy-emitting section 212 is set to 15cm, the focal length of the parabolic surface of the reflector 213 can be set to be greater than or equal to 1cm and less than or equal to 3cm, such as 1cm, 2cm, 2.2cm, 2.5cm, or 3cm, etc.; wherein, the refractive index of the energy-gathering and energy-emitting section can be 1.43, 1.435, 1.436, 1.44, 1.45, 1.455, 1.459, 1.46, or 1.47, etc., and is not specifically limited.

[0080] In this way, the irradiation area and heating distance of the heating component 20 can be guaranteed, so that as much radiant energy as possible can be radiated into the heating cavity 101. In some embodiments, the specific refractive index of the material of the energy focusing and output section 212, the focal length of the lens of the energy focusing and output section 212, and the focal length of the parabolic surface of the reflector 213 can be selected for the size of the heating cavity 101, as illustrated below.

[0081] In some embodiments, the heating cavity 101 of the cooking device has dimensions of 48cm*43cm*34cm, the focal length of the parabolic reflector 213 is 2cm, and the dimension of the reflector 213 in the first direction x is 9.6cm; the distance between the central axis of the first radiating element 22 and the bottom of the reflector 213 is 0.5cm, the focal length of the energy-concentrating and energy-emitting part 212 is 10.4cm, the dimension of the energy-concentrating and energy-emitting part 212 in the first direction x is 9.6cm, the thickness of the energy-concentrating and energy-emitting part 212 in the direction perpendicular to the first direction x is 0.3cm, and the refractive index of the energy-concentrating and energy-emitting part 212 is 1.47; the distance between two adjacent reflectors 213 is 15cm.

[0082] In one application scenario, refer to Figure 1 The first housing 10 forms a front sidewall and a rear sidewall that are arranged opposite to each other. The opening of the heating cavity 101 is located on the front sidewall. The front sidewall points to the rear sidewall in a direction parallel to the first direction x. A plurality of reflectors 213 are arranged at intervals along the first direction x. The second direction y is parallel to the direction from the top wall of the first housing 10 to the bottom wall of the first housing 10. The first direction x is perpendicular to the second direction y. The third direction z is perpendicular to the first direction x and the second direction y. The heating cavity 101 of the cooking equipment has dimensions of 48cm*43cm*34cm. The parabolic focal length of the reflector 213 is 2cm, and the dimension of the reflector 213 in the first direction x is 9.6cm. The distance between the central axis of the first radiating element 22 and the bottom of the reflector 213 in the second direction y is 0.5cm. The focal length of the energy-concentrating and energy-emitting part 212 is 10.4cm, the dimension of the energy-concentrating and energy-emitting part 212 in the first direction x is 9.6cm, the thickness of the energy-concentrating and energy-emitting part 212 in the second direction y is 0.3cm, and the refractive index is 1.47. The spacing between two adjacent reflectors 213 in the first direction x is 15cm.

[0083] This setup can reduce the irradiation area of ​​the heating element 20 by 50% to 70%, and can achieve uniform and effective radiation in an area 10 to 20 cm away from the heating element 20.

[0084] The first radiating element 22 may also be provided to extend in a direction perpendicular to the first direction x, with an extension length of 40cm. The first direction x is the arrangement direction of the multiple first radiating elements 22.

[0085] For example, such as Figure 1 As shown, the first radiating element 22 extends along a third direction z, which is perpendicular to both the first direction x and the second direction y. The first direction x is the direction in which multiple reflectors 213 are arranged at intervals, and the second direction y is parallel to the direction from the top wall of the first housing 10 to the bottom wall of the first housing 10, and the first direction x is perpendicular to the second direction y.

[0086] In some embodiments, the cooking device also includes a grill 50, which can be set inside the heating cavity 101 via guide rails 40, and can be used to place food to assist in cooking.

[0087] In some embodiments, the first housing 10 includes an outer shell and an inner shell, the outer shell forming an outer shell receiving cavity 201, the inner shell forming a heating cavity 101, and the inner shell being disposed within the outer shell; in some embodiments, the outer shell includes a heat-insulating material, which can achieve a heat-insulating effect and improve cooking speed.

[0088] In some embodiments, the cooking equipment includes cooking equipment with heating functions such as ovens and microwave-steam-grill combos, and the specific type is not limited.

[0089] The heating element 20 is installed in the oven to improve heating uniformity, increase utilization and heating efficiency, and enhance the user experience.

[0090] Unlike existing technologies, the cooking device of this application includes a first housing and a heating element. The first housing is provided with a heating cavity. The heating element includes a second housing with a receiving cavity and a first radiating element disposed in the receiving cavity. The second housing is provided with an energy blocking part and an energy concentrating and emitting part. The side of the energy blocking part facing the first radiating element forms a reflective surface. The radiant energy emitted by the first radiating element to the energy blocking part is reflected by the reflective surface to the energy concentrating and emitting part, so as to radiate from the energy concentrating and emitting part to the food heating area in the heating cavity. The energy-concentrating output section can gather the divergent radiant energy emitted by the first radiating element, improving the uniformity of heat radiation from the heating element. The energy-concentrating output section allows the gathered radiant energy to be radiated to the food heating zone within the heating cavity, facilitating directional energy concentration, improving the heating effect and speed of the food in the heating zone, and reducing heat loss caused by the radiant energy emitted by the first radiating element hitting the sidewalls of the heating cavity, thus improving the energy conversion efficiency of the cooking equipment. The reflective surface of the energy-blocking section reflects the radiant energy directed towards it back to the energy-concentrating output section, reducing heat loss caused by the radiant energy emitted by the first radiating element hitting the inner wall of the second housing, increasing the radiation amount of the energy-concentrating output section, and thus increasing the heat radiation intensity of the heating element, improving the energy utilization rate of the cooking equipment. Furthermore, the first radiating element is located within the accommodating cavity, reducing the risk of oil droplets or high-temperature steam splashing from the heating cavity contaminating the first radiating element, improving the ease of cleaning the cooking equipment.
