Description

Technical Field

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

[0002] One proposed solution involves an air fryer that uses a light wave heating element for heating. This type of air fryer uses a light wave heating element to heat food, increasing light wave radiation and achieving radiant heating. However, due to the irregularity of the light wave emission direction, only a small portion of the light wave energy is concentrated in the cooking zone of the air fryer, resulting in insignificant radiant heating.

[0003] Therefore, how to improve the radiant heating of light wave heating tubes has become an urgent problem to be solved. Utility Model Content

[0004] The present invention aims to at least solve the technical problem that radiation heating is not obvious when air fryers are heated by light wave heating tubes in the prior art or related technologies.

[0005] The first aspect of this utility model is to provide a cooking utensil.

[0006] To achieve the above objectives, an embodiment of the first aspect of this utility model provides a cooking appliance, comprising: a housing, wherein a cooking zone is disposed within the housing; a hot air fan rotatably disposed within the housing for driving airflow circulation in the cooking zone; a light wave heating tube installed within the housing, located on the air inlet side of the hot air fan, for heating the airflow flowing through the light wave heating tube and radiating heat to the cooking zone; and a reflector installed on the side of the light wave heating tube near the hot air fan, the reflector being used to reflect the heat radiation generated by the light wave heating tube into the cooking zone.

[0007] The cooking appliance provided by this utility model includes a shell, a hot air fan, a light wave heating tube, and a reflector. The shell constitutes the overall support structure of the appliance, and the cooking zone inside provides space for accommodating and cooking food (for placing ingredients, a frying pan or baking tray can be installed in the cooking zone). The hot air fan is rotatably installed inside the shell, and its function is to drive the airflow in the cooking zone to form a circulating flow, ensuring uniform heat distribution within the cavity; the light wave heating tube is installed inside the shell and is confined to the air intake side of the hot air fan. The light wave heating tube can directly heat the circulating airflow flowing over its surface, providing a high-temperature heat source for hot air circulation; furthermore, the light wave heating tube can utilize its radiation characteristics to directly emit radiant heat onto the food in the cooking zone for efficient grilling.

[0008] In existing solutions, the light wave heating element is typically positioned around the hot air fan, resulting in a distance between the element and the bottom of the cooking zone, leading to poor radiant heating of the food. This application, by placing the light wave heating element on the air intake side of the hot air fan, significantly shortens the radiant conduction distance between the element and the food in the cooking zone, effectively reducing the attenuation of light wave energy and thus enhancing the direct radiant heating intensity of the food. Simultaneously, the high-temperature airflow heated by the light wave heating element, driven by the hot air fan, forms circulating hot air, achieving convection heating. Ultimately, through the synergistic effect of radiant and convection heating, the cooking efficiency of the appliance is greatly improved, heating uniformity is enhanced, and the food achieves a crispy exterior and tender interior, resulting in an ideal texture.

[0009] Optionally, the cooking appliance includes a first cavity, which is a hot air cavity. The airflow inside the cavity can circulate under the action of a hot air fan to form a hot airflow, thereby heating the food. A cooking area is formed on one side of the hot air cavity along a first direction (e.g., the height direction or the front-back direction) for cooking the food, and an installation area is formed on the other side of the first cavity along the first direction for installing components such as the hot air fan and the light wave heating tube.

[0010] Meanwhile, the cooking appliance also includes a reflector, which is installed on the side of the light wave heating element closest to the hot air fan. The reflector effectively reflects the heat radiation emitted by the light wave heating element backward (towards the hot air fan) back into the cooking area. This reduces the backward loss and waste of light wave radiation energy to non-cooking areas, focusing more radiant heat energy onto the food surface in the cooking area. This significantly improves the radiant heat utilization efficiency of the light wave heating element, enhances the direct radiant heating intensity of the food, and ultimately further optimizes the cooking effect and overall energy efficiency.

[0011] In any of the above technical solutions, optionally, the reflector is located between the light wave heating tube and the hot air fan, or at least a portion of the reflector surrounds the hot air fan.

[0012] In this technical solution, the reflector can be installed directly between the light wave heating tube and the hot air fan. In this case, the hot air fan, reflector, and light wave heating tube are installed sequentially from top to bottom along the height direction, so that the hot air fan is located above the reflector. By installing the hot air fan above the reflector, the size of the hot air fan is not limited by the size of the reflector, allowing the size of the hot air fan to be set according to actual needs to ensure sufficient airflow. In other solutions, at least a portion of the reflector can be arranged around the hot air fan. In this case, at least a portion of the hot air fan is located inside the reflector, which helps to reduce the overall height of the unit.

[0013] In any of the above embodiments, optionally, at least a portion of the reflector surrounds the periphery of the light wave heating tube.

[0014] In this embodiment, at least a portion of the reflector is disposed around the periphery of the light wave heating tube, which can enhance the reflection of light waves by the reflector.

[0015] In any of the above technical solutions, optionally, the reflector includes a top wall and a side wall that are connected to each other, the side wall of the reflector extends from the hot air fan toward the light wave heating tube, and at least a portion of the side wall of the reflector surrounds the periphery of the light wave heating tube.

[0016] In this technical solution, the reflector includes a top wall and a side wall. The edge of the reflector bends towards the direction of the light wave heating tube to form the side wall. The combination of the top wall and the side wall can improve the reflective effect of the reflector and enhance the thermal radiation heating effect of the light wave heating tube.

[0017] When the reflector is installed, at least part of the side wall of the reflector can surround the periphery of the light wave heating tube. This can enhance the reflection effect of the light waves of the light wave heating tube through the side wall, and protect the light wave heating tube by the side wall, reducing the probability of the user touching the light wave heating tube when picking up or putting away the frying bucket, baking tray, etc. This can protect the light wave heating tube from damage and protect the user from burns.

[0018] Optionally, in any of the above technical solutions, a gap is provided between the side wall and / or the top wall of the reflector and the light wave heating tube.

[0019] In these technical solutions, the reflector is a cover-like structure that covers the outside of the light wave heating tube. The reflector maintains a certain distance from the light wave heating tube in both the vertical and horizontal directions. This distance can be greater than 3mm, which ensures that interference between the light wave heating tube and the reflector is not likely to occur.

[0020] In any of the above technical solutions, optionally, the reflector is annular, and an air passage is provided in the middle of the reflector for the passage of circulating airflow.

[0021] In these technical solutions, the reflector has a hollowed-out structure in the middle, and the hollowed-out part of the reflector forms an air passage. The annular reflector can efficiently reflect and focus the heat radiation emitted by the light wave heating tube to the front cooking area from all directions, significantly reducing the loss of radiant heat energy; at the same time, the air passage in the middle ensures that the heated circulating airflow can pass smoothly and without obstruction, avoiding interference with the airflow circulation caused by the reflector.

[0022] In any of the above technical solutions, optionally, the light wave heating tube includes an annular tube, the inner edge of which is flush with the inner wall of the air passage or the inner edge of which is located inside the inner wall of the air passage.

[0023] In these technical solutions, the light wave heating tube includes an annular tube, which allows airflow to pass through the center of the annular tube and then enter the hot air fan. The inner edge of the annular tube is flush with the inner wall of the air passage, meaning that the size and shape of the inner contour line of the annular tube and the inner wall of the air passage are basically the same. This allows both the light wave heating tube and the air passage to be designed to be relatively large. On the one hand, this ensures that the light wave heating tube does not obstruct the return air; on the other hand, it allows the fan blades of the hot air fan to be designed to be larger, thereby ensuring the suction power of the hot air fan and improving the efficiency of hot air circulation.

[0024] The inner edge of the annular tube is located inside the inner wall of the air passage. In other words, from the perspective of height, the annular tube is exposed from the air passage. This means that the annular tube will block the return air of the hot air fan. Therefore, in order to ensure that the reflector can reflect the radiation energy of the annular tube and the return air area, the inner diameter of the annular tube and the inner diameter of the air passage can be set to be equal.

[0025] Optionally, in any of the above technical solutions, the reflector is connected to a hot air fan. The direct connection between the reflector and the hot air fan ensures the stability and accuracy of its installation, thus solving the installation problem of the reflector.

[0026] In any of the above technical solutions, optionally, the reflector is located between the light wave heating tube and the hot air fan, the hot air fan is installed on the end face of the reflector away from the light wave heating tube, or at least part of the reflector surrounds the periphery of the hot air fan, and the inner wall of the reflector is connected to the outer side of the hot air fan.

[0027] In this technical solution, the blades of the hot air fan can be directly fixed to the reflector by welding or other methods, thus facilitating the easy and simple fixation of the reflector. The hot air fan includes blades, each with upper and lower edges. During installation, all blades can be directly installed on top of the reflector, with the bottom edge of the blades fixed to the reflector. To further reduce the overall height of the unit, the hot air fan section is positioned within the airflow channel. In this case, a portion of the reflector can be arranged around the periphery of the hot air fan, and the reflector can be directly connected and fixed to the peripheral edges of the blades.

[0028] Optionally, in any of the above technical solutions, the reflector includes a plurality of reflective sheets, at least a portion of which is mounted on the periphery of the hot air fan and connected to the hot air fan.

[0029] In these technical solutions, in addition to being a ring structure, the reflector can also be a structure formed by multiple reflective sheets. In this case, each reflective sheet is mounted on a hot air fan and connected to the hot air fan to reflect the light waves generated by the light wave heating tube.

[0030] In any of the above technical solutions, optionally, the hot air fan includes multiple blades, which are arranged sequentially along the circumference of the hot air fan, wherein: multiple reflective sheets are installed one-to-one on the multiple blades, and / or along the radial direction of the hot air fan, the reflective sheets are located on the outer side of the outer end of the blade and connected to the side wall surface of the outer end of the blade.

[0031] In these technical solutions, a reflector is installed on the radial outer end wall of each blade, which reflects the light waves generated by the light wave heating tube. During installation, the reflector can be directly installed on the outer end wall of the blade using screws or welding. By setting the reflector as multiple independent reflectors, the weight of the entire reflector can be reduced. This reduces wind resistance and lowers the rotational energy consumption of the hot air fan when the reflector is installed on it.

[0032] Alternatively, the reflector sheet is welded to the blade.

[0033] In any of the above technical solutions, optionally, the hot air fan, reflector, and light wave heating tube are arranged along the height direction of the cooking appliance and located above the cooking area.

[0034] In these technical solutions, the lower part of the casing forms the cooking area, while the upper part is the installation area, used for mounting the hot air fan, reflector, and light wave heating element. The hot air fan is located at the top, the reflector in the middle, and the light wave heating element is directly above the cooking area, allowing it to directly radiate heat to the cooking area to radiate heat to the food or air within. By arranging the cooking area and installation area vertically, vertical space can be efficiently utilized, resulting in a thinner product. For example, air fryers and top-heated ovens often use this layout.

[0035] In other designs, the cooking and installation areas can be arranged front to back to utilize the space in the front-to-back direction, thereby reducing the overall height of the machine. For example, this layout is often used in ovens with rear heating.

[0036] Optionally, the light wave heating tube and the reflector are spaced apart along the height direction, meaning they do not contact each other. This prevents the reflector from contacting the light wave heating tube and damaging it during rotation with the hot air fan. Furthermore, the absence of contact between the light wave heating tube and the reflector creates an airflow channel between them, ensuring that the heated airflow passes smoothly and evenly through this gap. This avoids airflow obstruction or turbulence caused by insufficient spacing, thus guaranteeing the efficiency and stability of the hot air circulation.

[0037] Optionally, the distance between the light wave heating tube and the reflector is greater than 3 mm. Optionally, the distance between the edge of the light wave heating tube and the reflector is consistent, for example, the distance between the light wave heating tube and the reflector is consistent in both the height direction and the horizontal direction.

[0038] In any of the above technical solutions, optionally, the light wave heating tube and the hot air fan are arranged at intervals along the height direction.

[0039] In these technical solutions, the light wave heating tube and the hot air fan are spaced apart to avoid interference between the light wave heating tube and the hot air fan, which would affect the rotation of the hot air fan.

[0040] Optionally, the distance between the light wave heating tube and the hot air fan is greater than 3mm, which can effectively avoid interference between the light wave heating tube and the hot air fan.

[0041] Optionally, in any of the above technical solutions, the cooking appliance further includes: a deflector, disposed within the housing, for dividing the housing into a first cavity and a second cavity along the height direction of the cooking appliance, the first cavity including an installation area and a cooking area, a hot air fan and a light wave heating tube disposed in the installation area, and the cooking area for cooking food.

[0042] In these technical solutions, the cooking appliance also includes a deflector, which is disposed inside the housing and divides the interior of the housing into a first cavity and a second cavity that are independent of each other along the height direction of the cooking appliance; wherein, the first cavity includes an installation area for installing a hot air fan and a light wave heating tube and a cooking area for cooking food, and the hot air fan and the light wave heating tube are disposed in the installation area. The air deflector firstly serves an important spatial separation function, placing the installation area containing high-temperature working components (hot air fan, light wave heating tube) and the cooking area within the first cavity, achieving thermal and spatial isolation from the second cavity. This makes the overall structure more compact and rational, and protects other components (such as circuit elements) within the second cavity from high temperatures. Secondly, the air deflector itself has a crucial airflow guiding function, constraining and guiding the circulating airflow generated by the hot air fan. This allows the airflow to flow more concentratedly and orderly over the surface of the light wave heating tube and be heated before being delivered to the cooking area. This effectively reduces the disorderly diffusion and energy loss of hot air within the first cavity, optimizes the airflow path, and improves heat exchange efficiency and heating uniformity.

[0043] The second cavity is the electronic control area, where components such as a motor and an electronic control board can be installed. The motor connects to the hot air fan to drive its rotation. The electronic control board controls the operation of the entire cooking appliance.

[0044] In any of the above technical solutions, optionally, the flow guide includes a top and a side that are connected to each other, and along the height direction, the height of the lower end face of the side of the flow guide is lower than the height of the lower end face of the light wave heating tube.

[0045] In these technical solutions, the downward-extending side and top of the air deflector together form an optimized airflow channel, which better constrains and guides the airflow generated by the hot air fan. This allows the airflow to more fully exchange heat with the light wave heating element before entering the cooking zone along a preset path, significantly improving the directionality and heat exchange efficiency of the hot air circulation. Furthermore, the lower end of the side of the air deflector is lower than the lower end of the light wave heating element. This allows the light wave heating element to be enclosed in the center by the side of the air deflector, protecting it and reducing the probability of users touching the light wave heating element when handling frying pans, baking trays, etc. This protects both the light wave heating element from damage and the user from burns.

[0046] The fairing includes a top and a side portion connected to each other; the reflector includes a top wall and a side wall connected to each other, the top wall of the reflector being parallel to the top of the fairing, and / or the side wall of the reflector being parallel to the side portion of the fairing, and / or the top wall and the side wall of the reflector being connected by a first arcuate portion, the top of the fairing and the side portion of the fairing being connected by a second arcuate portion, the first arcuate portion and the second arcuate portion being parallel to each other.

[0047] In these technical solutions, the shapes of the reflector and the guide shield are quite similar, both including horizontally and vertically arranged structures. Simultaneously, a relatively regular-shaped, uniformly spaced airflow channel is formed between the corresponding walls of the reflector and the guide shield. This airflow channel effectively constrains and guides the circulating airflow generated by the hot air fan, allowing the airflow to flow smoothly and steadily along a pre-set annular path. This greatly reduces turbulence, eddies, and wind resistance losses caused by abrupt changes in the channel shape within a narrow space, ensuring efficient transmission of airflow power.

[0048] Optionally, in any of the above technical solutions, the cooking appliance may also include a fixing member, which is disposed on the light wave heating tube and connected to the guide cover.

[0049] In these technical solutions, the light wave heating tube can be installed on the guide shroud by a fastener, avoiding interference between the light wave heating tube and the reflector, thus solving the installation problem of the light wave heating tube simply and at low cost.

[0050] In any of the above technical solutions, optionally, the top wall of the reflector is arranged parallel to the end face of the hot air fan at the end away from the reflector.

[0051] In these technical solutions, the upper surface of the reflector is parallel to the airflow direction of the hot air fan blades, which helps the hot air to be transferred to the cooking area between the hot air fan blades and the reflector.

[0052] In any of the above technical solutions, optionally, the reflector includes a metal cover. A metal cover has high reflectivity, which can improve the reflector's ability to reflect light waves and enhance the radiant heating effect of the light wave heating tube on the food.

[0053] Light wave heating tubes can be specifically quartz tubes, halogen tubes, etc.

[0054] Optionally, the cooking appliance also includes a protective cover disposed within the first cavity to divide the first cavity into an installation area and a cooking area. The cooking area forms a cooking chamber for directly cooking food. Alternatively, the cooking appliance may also include a frying bucket and / or a baking tray, detachably installed in the cooking area, with the frying bucket forming a cooking chamber for cooking food, and the baking tray used to hold food for cooking.

[0055] Alternatively, the cooking appliance may include an air fryer, an oven, or a steam oven.

[0069] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0070] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0071] The following reference Figures 1 to 9 The following describes the cooking appliances provided in the embodiments of this application.

[0072] like Figures 1 to 9 As shown, an embodiment of the first aspect of this utility model provides a cooking appliance, including a housing 1, a hot air fan 2, a light wave heating tube 3, and a reflector 4. A cooking zone 124 is disposed within the housing 1. The hot air fan 2 is rotatably disposed within the housing 1 to drive the airflow in the cooking zone 124 to circulate. The light wave heating tube 3 is installed within the housing 1, located on the air inlet side of the hot air fan 2, to heat the airflow flowing through the light wave heating tube 3 and to radiate heat to the cooking zone 124. The reflector 4 is installed on the side of the light wave heating tube 3 near the hot air fan 2, and is used to reflect the heat radiation generated by the light wave heating tube 3 into the cooking zone 124.

[0073] The cooking appliance provided by this utility model includes a housing 1, a hot air fan 2, a light wave heating tube 3, and a reflector 4. The housing 1 forms the overall support structure of the appliance, and the cooking zone 124 inside provides space for accommodating and cooking food (for placing ingredients, a frying pan or baking tray 7, etc., can be installed in the cooking zone 124). The hot air fan 2 is rotatably installed inside the housing 1, and its function is to drive the airflow in the cooking zone 124 to form a circulating flow, ensuring the uniform distribution of heat in the cavity; the light wave heating tube 3 is installed inside the housing 1, and the light wave heating tube 3 is confined to the air inlet side of the hot air fan 2. The light wave heating tube 3 can directly heat the circulating airflow flowing over its surface, providing a high-temperature heat source for hot air circulation; on the other hand, the light wave heating tube 3 can utilize its radiation characteristics to directly emit radiant heat to the food in the cooking zone 124 to achieve efficient grilling.

[0074] In some existing solutions, the light wave heating element is typically positioned around the hot air fan, resulting in a distance between the element and the bottom of the cooking zone, leading to poor radiant heating of the food. This application, by placing the light wave heating element 3 on the air inlet side of the hot air fan 2, significantly shortens the radiant conduction distance between the element 3 and the food in the cooking zone 124, effectively reducing the attenuation of light wave energy and thus enhancing the direct radiant heating intensity of the food. Simultaneously, the high-temperature airflow heated by the light wave heating element 3, driven by the hot air fan 2, forms circulating hot air, achieving convection heating. Ultimately, through the synergistic effect of radiant and convection heating, the cooking efficiency of the cooking appliance is significantly improved, heating uniformity is enhanced, and the food achieves a crispy exterior and tender interior, resulting in an ideal texture.

[0075] Optionally, the cooking appliance includes a first cavity 12, which is a hot air cavity. The airflow inside the cavity can circulate under the action of the hot air fan 2 to form a hot air flow, thereby heating the food. A cooking area 124 is formed on one side of the hot air cavity along a first direction (e.g., the height direction or the front-back direction) for cooking the food. An installation area 122 is formed on the other side of the first cavity 12 along the first direction for installing components such as the hot air fan 2 and the light wave heating tube 3.

[0076] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cooking appliance also includes a reflector 4, which is installed on the side of the light wave heating tube 3 near the hot air fan 2, that is, the reflector 4 is positioned close to the hot air fan 2. The reflector 4 can effectively reflect the heat radiation emitted by the light wave heating tube 3 backward (i.e., towards the hot air fan 2) into the cooking area 124 in front (the reflection path can be as follows). Figure 5(As shown by the dashed arrow in the image), this reduces the backward loss and waste of light wave radiation energy to the non-cooking area 124, focuses more radiant heat energy and delivers it to the food surface in the cooking area 124, thereby greatly improving the radiant heat utilization efficiency of the light wave heating tube 3, enhancing the direct radiant heating intensity of the food, and ultimately further optimizing the cooking effect and overall energy efficiency of the food.

[0077] like Figure 4 As shown, the area enclosed by the lower surface of the reflector 4 constitutes the return air zone 9 of the hot air fan.

[0078] The central part of the reflector 4 is the air outlet area, which is provided with an air passage 42. The outer wall surface of the reflector 4 is formed as a guide surface 40 to guide the hot airflow, and the inner wall surface of the reflector 4 is formed as a reflective surface 41 to reflect light waves.

[0079] In any of the above embodiments, optionally, at least a portion of the reflector 4 surrounds the periphery of the light wave heating tube 3.

[0080] In this embodiment, at least a portion of the reflector 4 is disposed around the periphery of the light wave heating tube 3, which can enhance the reflection of light waves by the reflector 4.

[0081] In any of the above embodiments, optionally, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the reflector 4 is located between the light wave heating tube 3 and the hot air fan 2, or at least a portion of the reflector 4 surrounds the hot air fan 2.

[0082] In this embodiment, when installing the reflector 4, it can be directly installed between the light wave heating tube 3 and the hot air fan 2. In this case, the hot air fan 2, reflector 4, and light wave heating tube 3 are installed sequentially from top to bottom along the height direction, so that the hot air fan 2 is located above the reflector 4. By installing the hot air fan 2 above the reflector 4, the size of the hot air fan 2 is not limited by the size of the reflector 4. Thus, the size of the hot air fan 2 can be set according to actual needs to ensure the airflow of the hot air fan 2. In other solutions, at least a portion of the reflector 4 can be arranged around the hot air fan 2. In this case, at least a portion of the hot air fan 2 is located inside the reflector 4, which helps to reduce the overall height of the unit.

[0083] In any of the above embodiments, optionally, as Figure 1 and Figure 8 As shown, the reflector 4 includes a top wall 44 and a side wall 46 connected to each other. The side wall 46 of the reflector 4 extends from the hot air fan 2 toward the light wave heating tube 3, and at least a portion of the side wall 46 of the reflector 4 surrounds the periphery of the light wave heating tube 3.

[0084] In this embodiment, the reflector 4 includes a top wall 44 and a side wall 46. The edge of the reflector 4 is bent toward the light wave heating tube 3 to form the side wall 46. The combination of the top wall 44 and the side wall 46 can improve the reflection effect of the reflector 4 and improve the thermal radiation heating effect of the light wave heating tube 3.

[0085] When the reflector 4 is installed, at least a portion of the side wall 46 of the reflector 4 can surround the periphery of the light wave heating tube 3. In this way, on the one hand, the side wall 46 can enhance the reflection effect of the light waves of the light wave heating tube 3, and on the other hand, the side wall 46 can protect the light wave heating tube 3, reducing the probability of the user touching the light wave heating tube 3 when taking out the frying bucket, baking tray 7, etc. This can protect the light wave heating tube 3 from damage and protect the user from burns.

[0086] In any of the above embodiments, optionally, as Figure 1 and Figure 8 As shown, a gap is provided between the side wall 46 and / or the top wall 44 of the reflector 4 and the light wave heating tube 3.

[0087] In these embodiments, the reflector 4 is a cover-like structure that covers the outside of the light wave heating tube 3. The reflector 4 maintains a certain distance from the light wave heating tube 3 in both the vertical and horizontal directions. This distance can be greater than 3mm, so as to ensure that interference does not easily occur between the light wave heating tube 3 and the reflector 4.

[0088] Optionally, such as Figure 1 and Figure 8 As shown, the top wall 44 and side wall 46 of the reflector 4 are connected by the first arc-shaped part 48, so that the top wall 44 and side wall 46 can be smoothly transitioned, and the interior of the reflector 4 can form a smooth surface, which is beneficial to the reflection of light waves.

[0089] In any of the above embodiments, optionally, as Figure 2 , Figure 3 and Figure 4 As shown, the reflector 4 is annular, and an air passage 42 is provided in the middle of the reflector 4. The air passage 42 is used to allow circulating airflow to pass through.

[0090] In these embodiments, the reflector 4 has a hollowed-out structure in the middle, and the hollowed-out part of the reflector 4 forms an air passage 42. The annular reflector 4 can efficiently reflect and focus the heat radiation emitted by the light wave heating tube 3 to the front cooking area 124 from all directions, significantly reducing the loss of radiant heat energy; at the same time, the air passage 42 in the middle ensures that the heated circulating airflow can pass smoothly and without obstruction, avoiding interference with the airflow circulation caused by the reflector 4.

[0091] In any of the above embodiments, optionally, as Figure 6 As shown, the light wave heating tube 3 includes an annular tube, the inner edge of which is flush with the inner wall of the air passage 42 or the inner edge of which is located inside the inner wall of the air passage 42.

[0092] In these embodiments, the light wave heating tube 3 includes an annular tube, which allows airflow to pass through the middle of the annular tube and then enter the hot air fan 2. The inner edge of the annular tube is flush with the inner wall of the air passage 42, meaning that the size and shape of the inner contour line of the annular tube and the inner wall of the air passage 42 are basically the same. This allows both the light wave heating tube 3 and the air passage 42 to be designed to be relatively large. On the one hand, this ensures that the light wave heating tube 3 does not obstruct the return air, and on the other hand, it allows the fan blades of the hot air fan 2 to be designed to be relatively large, thereby ensuring the suction power of the hot air fan 2 and improving the efficiency of hot air circulation.

[0093] The inner edge of the annular tube is located inside the inner wall of the air passage 42, which means that, from the perspective of height, the annular tube is exposed from the air passage 42. In this way, the annular tube will block the return air of the hot air fan 2. Therefore, in order to ensure that the reflector 4 can reflect the radiation energy of the annular tube and the return air area, the inner diameter of the annular tube and the inner diameter of the air passage 42 can be set to be equal.

[0094] For example, such as Figure 7 As shown, the reflector 4 is circular, the light wave heating tube 3 is circular, and the inner diameter D3 formed by the side wall 46 of the reflector 4 is larger than the outer diameter D4 of the light wave heating tube 3.

[0095] In any of the above embodiments, optionally, the reflector 4 is connected to the hot air fan 2. The direct connection between the reflector 4 and the hot air fan 2 ensures the stability and accuracy of its installation, thus solving the installation problem of the reflector 4.

[0096] In any of the above embodiments, optionally, the reflector 4 is located between the light wave heating tube 3 and the hot air fan 2, the hot air fan 2 is installed on the end face of the reflector 4 away from the light wave heating tube 3, or at least a portion of the reflector 4 surrounds the periphery of the hot air fan 2, and the inner wall of the reflector 4 is connected to the outer side of the hot air fan 2.

[0097] In this embodiment, the blades 22 of the hot air fan 2 can be directly fixed to the reflector 4 by welding or other methods, thus facilitating the easy and simple fixation of the reflector 4. The hot air fan 2 includes blades 22, each with upper and lower edges. During installation, all blades 22 can be directly installed above the reflector 4, with the bottom edge of the blades 22 fixed to the reflector 4. To further reduce the overall height, part of the hot air fan 2 is housed within the air passage 42. In this case, a portion of the reflector 4 can surround the periphery of the hot air fan 2, and the reflector 4 can be directly connected and fixed to the periphery of the blades 22.

[0098] In any of the above embodiments, optionally, the reflector 4 includes a plurality of reflective sheets 49, at least a portion of which is mounted on the periphery of the hot air fan 2 and connected to the hot air fan 2.

[0099] In these embodiments, in addition to being a ring structure, the reflector 4 can also be a structure formed by multiple reflective sheets 49. In this case, each reflective sheet 49 is mounted on the hot air fan 2 and connected to the hot air fan 2 to reflect the light waves generated by the light wave heating tube 3.

[0100] In any of the above embodiments, optionally, as Figure 9 As shown, the hot air fan 2 includes multiple blades 22. The multiple blades 22 are arranged sequentially along the circumference of the hot air fan 2. Optionally, multiple reflective sheets 49 are mounted one-to-one on the multiple blades 22. Optionally, along the radial direction of the hot air fan 2, the reflective sheets 49 are located outside the outer end of the blade 22 and are connected to the sidewall 46 surface of the outer end of the blade 22.

[0101] In these embodiments, a reflector 49 is installed on the radially outer end sidewall 46 of each blade 22, which can reflect the light waves generated by the light wave heating tube 3. During installation, the reflector 49 can be directly installed on the outer end sidewall 46 of the blade 22 by screws or welding. By setting the reflector 4 as multiple independent reflectors 49, the weight of the entire reflector 4 can be reduced. This reduces wind resistance and the rotational energy consumption of the hot air fan 2 when the reflector 4 is installed on the hot air fan 2.

[0102] Alternatively, the reflector 49 is welded together with the blade 22.

[0103] In any of the above embodiments, optionally, as Figure 1 and Figure 5As shown, the hot air fan 2, reflector 4, and light wave heating tube 3 are arranged along the height of the cooking appliance and are located above the cooking zone 124. In these embodiments, the cooking zone 124 is formed below the housing 1, and the mounting zone 122 is above it. The mounting zone 122 is used to install the hot air fan 2, reflector 4, and light wave heating tube 3. The hot air fan 2 is located at the top, the reflector 4 is located in the middle, and the light wave heating tube 3 is directly located above the cooking zone 124, so that the light wave heating tube 3 can directly radiate heat to the cooking zone 124 to radiate heat the food or air in the cooking zone 124. By arranging the cooking zone 124 and the mounting zone 122 vertically, the height space can be made reasonable, resulting in a thinner product. For example, air fryers and ovens with top heating 52 often adopt this layout.

[0104] In other designs, the cooking zone 124 and the installation zone 122 can also be arranged front to back to utilize the space in the front-back direction, thereby reducing the overall height of the machine. For example, this layout is often used in ovens with rear heating.

[0105] Optionally, such as Figure 6 As shown, the light wave heating tube 3 and the reflector 4 are spaced apart along the height direction, meaning the light wave heating tube 3 and the reflector 4 do not contact each other. This prevents the reflector 4 from contacting the light wave heating tube 3 and damaging it during rotation with the hot air fan 2. Furthermore, the absence of contact between the light wave heating tube 3 and the reflector 4 creates an airflow channel between them, ensuring that the heated airflow can pass smoothly and evenly through this gap. This avoids airflow obstruction or turbulence caused by excessively small spacing, thus guaranteeing the efficiency and stability of the hot air circulation.

[0106] Optionally, such as Figure 6 As shown, the distance H3 between the light wave heating tube 3 and the reflector 4 is greater than 3 mm. Optionally, the distance between the edge of the light wave heating tube 3 and the reflector 4 is the same, for example, the distance between the light wave heating tube 3 and the reflector 4 is the same in both the height direction and the horizontal direction.

[0107] In any of the above embodiments, optionally, as Figure 1 As shown, along the height direction, the light wave heating tube 3 and the hot air fan 2 are arranged at intervals.

[0108] In these embodiments, the light wave heating tube 3 and the hot air fan 2 are spaced apart, which can prevent the light wave heating tube 3 from interfering with the hot air fan 2 and affecting the rotation of the hot air fan 2.

[0109] Optionally, the distance between the light wave heating tube 3 and the hot air fan 2 is greater than 3mm, which can effectively prevent interference between the light wave heating tube 3 and the hot air fan 2.

[0110] In any of the above embodiments, optionally, as Figure 1 , Figures 5 to 8 As shown, the cooking appliance also includes a deflector 5. The deflector 5 is disposed inside the housing 1 and is used to divide the housing 1 into a first cavity 12 and a second cavity 14 along the height direction of the cooking appliance. The first cavity 12 includes an installation area 122 and a cooking area 124. The hot air fan 2 and the light wave heating tube 3 are disposed in the installation area 122, and the cooking area 124 is used for cooking food.

[0111] In these embodiments, the cooking appliance also includes a flow guide 5, which is disposed inside the housing 1 and divides the interior of the housing 1 into a first cavity 12 and a second cavity 14 that are independent of each other along the height direction of the cooking appliance; wherein, the first cavity 12 includes an installation area 122 for installing a hot air fan 2 and a light wave heating tube 3 and a cooking area 124 for cooking food, and the hot air fan 2 and the light wave heating tube 3 are disposed in the installation area 122. The air deflector 5 firstly serves an important spatial separation function, placing the installation area 122 (containing the high-temperature working components, hot air fan 2 and light wave heating tube 3) and the cooking area 124 within the first cavity 12, and achieving thermal and spatial isolation from the second cavity 14. This makes the overall structure more compact and reasonable, and protects other components (such as circuit elements) within the second cavity 14 from high temperatures. Secondly, the air deflector 5 itself has a crucial air guiding function, which can constrain and guide the circulating airflow generated by the hot air fan 2, making the airflow more concentrated and orderly flow over the surface of the light wave heating tube 3 and be heated, before being transported to the cooking area 124. This effectively reduces the disorderly diffusion and energy loss of hot air within the first cavity 12, optimizes the airflow path, and improves heat exchange efficiency and heating uniformity.

[0112] The second cavity 14 is the electronic control area, where components such as a motor 8 and an electronic control board can be installed. The motor 8 is used to connect to the hot air fan 2 to drive its rotation. The electronic control board is used to control the operation of the entire cooking appliance.

[0113] In any of the above embodiments, optionally, as Figure 1 As shown, the flow guide 5 includes a top 52 and a side 54 that are connected to each other. Along the height direction, the height of the lower end face of the side 54 of the flow guide 5 is lower than the height of the lower end face of the light wave heating tube 3.

[0114] In these embodiments, the downward-extending side portion 54 of the air deflector 5, together with the top portion 52, forms an optimized airflow channel. This channel provides better constraint and guidance for the airflow generated by the hot air fan 2, allowing the airflow to more fully exchange heat with the light wave heating tube 3 before entering the cooking zone 124 via a preset path. This significantly improves the directionality of the hot air circulation and the efficiency of heat exchange. Furthermore, the lower end face of the side portion 54 of the air deflector 5 is lower than the lower end face of the light wave heating tube 3. The side portion 54 of the air deflector 5 can enclose the light wave heating tube 3 in the center, protecting it and reducing the probability of the user touching the light wave heating tube 3 when handling the fryer, baking tray 7, etc. This protects the light wave heating tube 3 from damage and also protects the user from burns.

[0115] A gap H1 is provided between the lower end face of the side 54 of the flow guide shroud 5 and the lower end face of the light wave heating tube 3, and H1 is greater than 3mm.

[0116] Optionally, such as Figure 1 and Figure 8 As shown, the fairing 5 includes a top 52 and a side 54 connected to each other; the reflector 4 includes a top wall 44 and a side wall 46 connected to each other. The top wall 44 of the reflector 4 is arranged parallel to the top 52 of the fairing 5, and / or the side wall 46 of the reflector 4 is arranged parallel to the side 54 of the fairing 5, and / or the top wall 44 of the reflector 4 and the side wall 46 of the reflector 4 are connected by a first arcuate portion 48, and the top 52 of the fairing 5 and the side 54 of the fairing 5 are connected by a second arcuate portion 56. The first arcuate portion 48 and the second arcuate portion 56 are arranged parallel to each other.

[0117] In these embodiments, the shapes of the reflector 4 and the guide shield 5 are quite similar, both including horizontally arranged structures and vertically arranged structures. Simultaneously, a relatively regular-shaped and uniformly spaced airflow channel is formed between the corresponding walls of the reflector 4 and the guide shield 5. This airflow channel effectively constrains and guides the circulating airflow generated by the hot air fan 2, allowing the airflow to flow smoothly and steadily along a preset annular path. This greatly reduces turbulence, eddies, and wind resistance losses caused by abrupt changes in the channel shape within a narrow space, ensuring efficient transmission of airflow power.

[0118] In any of the above embodiments, optionally, as Figure 1 and Figure 5 As shown, the cooking appliance also includes a fixing member 6, which is mounted on the light wave heating tube 3 and connected to the guide cover 5.

[0119] In these embodiments, the light wave heating tube 3 can be installed on the guide shroud 5 by means of the fastener 6, so as to avoid interference between the light wave heating tube 3 and the reflector 4, and to solve the installation problem of the light wave heating tube 3 simply and at low cost.

[0120] In any of the above embodiments, optionally, as Figure 1 and Figure 8 As shown, the top wall 44 of the reflector 4 is arranged parallel to the end face of the hot air fan 2 away from the reflector 4.

[0121] In these embodiments, the upper surface of the reflector 4 is parallel to the airflow direction of the fan blades of the hot air fan 2, which helps the hot air to be transferred between the fan blades of the hot air fan 2 and the reflector 4 to the cooking area 124.

[0122] In any of the above embodiments, the reflector 4 may optionally include a metal cover. The metal cover has high reflectivity, which can improve the reflective effect of the reflector 4 on light waves and enhance the radiant heating effect of the light wave heating tube 3 on the food.

[0123] The light wave heating tube 3 can be a quartz tube, a halogen tube, etc.

[0124] Optionally, the cooking appliance also includes a protective cover disposed within the first cavity 12 to divide the first cavity 12 into an installation area 122 and a cooking area 124. The cooking area 124 forms a cooking chamber for directly cooking food. Alternatively, the cooking appliance may also include a frying pan and / or a baking pan 7, detachably installed in the cooking area 124, with the frying pan forming a cooking chamber for cooking food, and the baking pan 7 used to hold food for cooking.

[0125] Alternatively, the cooking appliance may include an air fryer, an oven, or a steam oven.

[0126] in, Figure 4 and Figure 8 The solid arrows in the image indicate the direction of airflow. Figure 5 The dashed arrows in the diagram indicate the reflection paths of the heat radiation reflected into the cooking zone 124.

[0127] The following section uses an air fryer as an example to further illustrate the cooking appliances in this application.

[0128] In the relevant solutions, air fryers use a motor to drive fan blades in the cooking chamber to heat food during the cooking process. Specifically, air fryers transfer heat from the heating element through airflow via thermal convection, thus heating the food. However, because metal heating elements lack light radiation, their ability to penetrate and heat food is weak, resulting in food that is easily burnt on the surface while remaining uncooked inside.

[0129] To solve the above technical problems, the relevant solutions use light wave heating tubes to heat food. Although this increases light wave radiation, the irregularity of the light wave emission direction means that only a small portion of the light wave energy is concentrated in the baking pan area of ​​the cooking cavity, so the increase in effect is not significant.

[0130] To address the aforementioned issues, this embodiment provides an air fryer equipped with a rotatable energy-concentrating fan blade structure (i.e., a combination of a hot air fan 2 and a reflector 4). This rotatable energy-concentrating fan blade structure enhances the ability of light waves to penetrate and heat food during radiant heating by the light wave heating tube.

[0131] The air fryer includes a shell 1, a hot air fan 2 for circulating airflow, a light wave heating element 3 for heating, and a reflector 4 disposed between the hot air fan 2 and the light wave heating element 3. Additionally, the air fryer of this embodiment also has the following structural design:

[0132] 1. For example Figure 1 As shown, the distance H1 between the lower end face of the light wave heating tube 3 and the lower end face of the guide shroud 5 is greater than 3 mm, and the distance H2 between the light wave heating tube 3 and the hot air fan 2 along the height direction is greater than 3 mm.

[0133] 2. The reflector 4 is connected to the fan blade.

[0134] 3. The reflector 4 is made of a high-reflectivity, heat-resistant metallic material.

[0135] 4. For example Figure 5 As shown, the light wave heating tube 3 is connected and fixed to the flow guide shroud 5 through the fixing member 6.

[0136] 5. For example Figure 6 As shown, the distance H3 between the reflector 4 and the light wave heating tube 3 is greater than 3 mm.

[0137] 6. For example Figure 6 As shown, the inner diameter D1 of the upper end face of the reflector 4 is equal to the inner diameter D2 of the light wave heating tube 3.

[0138] 7. For example Figure 7 As shown, the inner diameter D3 of the lower end face of the reflector 4 is greater than the outer diameter D4 of the light wave heating tube 3.

[0139] 8. The angle A between the upper end face of the reflector 4 and the lower end face of the fan blade is 0° (i.e., they are parallel).

[0140] 9. The angle B between the side wall of the reflector 4 and the side of the fairing is 0° (i.e., they are parallel).

[0141] 10. The arc surface of the reflector 4 is parallel to the arc surface of the fairing 5.

[0142] The air fryer according to this embodiment can achieve the following beneficial effects:

[0143] 1. The light wave heating tube 3 is located between the fan blade and the frying drum. It can shorten the distance between the light wave heating tube 3 and the baking tray in the cooking area while ensuring that the light wave heating tube 3 does not interfere with the food when the frying drum is put in or out, thereby enhancing the radiant heating effect of the light wave heating tube 3 on the food in the cooking area.

[0144] 2. The reflector 4 is connected to the fan blades, which can quickly transfer the heat of the reflector 4 to the food through heat conduction and heat convection.

[0145] 3. The reflector 4 is made of a heat-resistant metal material with high reflectivity. Through the reflector 4, part of the radiation energy of the light wave heating tube 3 can be reflected to the baking pan and other objects in the cooking area through the metal material, thereby improving the utilization rate of the radiation energy of the light wave heating tube 3.

[0146] 4. The light wave heating tube 3 is fixed to the flow guide shroud 5 by a fixing plate, which can fix the light wave heating tube 3 and ensure that the position between the light wave heating tube 3 and the reflector 4 is not affected.

[0147] 5. The distance H3 between the reflector 4 and the light wave heating tube 3 is greater than 3mm, which can prevent the reflector 4 from contacting the light wave heating tube 3 and damaging the light wave heating tube 3 during the rotation with the fan blade.

[0148] 6. The inner diameter D1 of the upper end face of the reflector 4 is equal to the inner diameter D2 of the light wave heating tube 3, so that the reflector 4 can ensure that the hot air can flow back to the fan blade through the center of the light wave heating tube 3 and then be emitted again from all sides while reflecting all the radiation energy of the upper part of the light wave heating tube 3.

[0149] 7. The inner diameter D3 of the lower end face of the reflector 4 is greater than the outer diameter D4 of the light wave heating tube 3, which can prevent the reflector 4 from contacting the light wave heating tube 3 and damaging the light wave heating tube 3 during the rotation with the fan blade.

[0150] 8. The angle A = 0° between the upper end face of the reflector 4 and the lower end face of the fan blade makes the upper end face of the reflector 4 parallel to the air outlet direction of the fan blade, which helps the hot air to be transferred to the cooking cavity along the fan blade and the reflector 4.

[0151] 9. The angle B between the side wall of the reflector 4 and the side of the air guide 5 is 0°, so that the air outlet direction of the side wall of the reflector 4 and the side of the air guide 5 is parallel, which helps the hot air to be transferred to the cooking cavity along the space between the reflector 4 and the air guide 5.

[0152] 10. The arc surface of the reflector 4 is parallel to the arc surface of the air guide 5, so that the reflector 4 and the air guide 5 are parallel to the air outlet direction, which helps the hot air to be transferred to the cooking cavity along the space between the reflector 4 and the air guide 5.

[0153] This embodiment introduces a rotatable energy-concentrating fan blade structure. The fan blade is driven by a motor 8 to achieve the heating function. The reflector 4 is divided into an air outlet area, an air guide area, and a reflection area. The reflection area faces the light wave heating tube 3 and is made of mirror aluminum or other sprayed materials that reflect light waves. It can reflect the originally scattered radiant heat transfer direction of the light wave heating tube 3 to the baking pan area, improving the energy utilization rate of the heat tube. At the same time, the air guide area of ​​the fan blade can work with the air guide shroud 5 to guide the airflow.
