Description

Technical Field

[0001] This utility model relates to the field of cooking device technology, and in particular to an electric oven. Background Technology

[0002] Currently, electric grills generally have a three-layer structure. The bottom layer is an open water tank; the middle layer is the grill body, including the heater and skewer rack, with the heater mainly located below the rack; and the top layer is an insulated space for keeping cooked skewers warm. Since the heater is located above the water tank, a large portion of the heat energy is absorbed by the surrounding space, the tank walls, and the water itself, resulting in low energy utilization for grilling. Furthermore, the heater's location below the rack means that grease dripping onto it easily carbonizes, making cleaning difficult. Additionally, grease dripping onto the hot heater can easily cause open flames, and the heat generated by the heater radiates directly outwards, heating the surrounding air and raising the ambient temperature. Users and customers are directly exposed to this radiant heat, resulting in a high perceived temperature.

[0003] Furthermore, the exhaust vents of electric grills are usually located below the skewers to achieve better smoke extraction and for the convenience of customers. However, some of the heat from the bottom-mounted heater is also exhausted through the exhaust system before reaching the food, which further exacerbates the problem of low overall heat utilization efficiency of electric grills.

[0004] Furthermore, the bottom-mounted heater cannot provide enough heat to the food-keeping zone located at the top of the electric oven, causing the heated food to cool down quickly and affecting its edibility. Summary of the Invention

[0005] In view of this, the present invention provides an electric oven that improves energy utilization, reduces heat radiation to users, and reduces the risk of grease dripping onto the heater surface and causing open flames.

[0011] Optionally, the electric oven also includes a water tank, the upper opening of which is located below the grill and corresponds vertically to the grill; the air duct is located outside the water tank and is arranged adjacent to the water tank.

[0012] Optionally, the reflector is an integrated bent structure.

[0013] Optionally, the reflector includes a top plate and side plates, the side plates include a first side plate and a second side plate, the top plate is disposed above the heater, and the two ends of the top plate are respectively connected to the downwardly extending first side plate and second side plate, the top plate, the first side plate and the second side plate surround at least a portion of the top and sides of the heater; and / or, the reflector further includes a first extension plate and a second extension plate, the first extension plate being formed by bending the first side plate inward, and the second extension plate being formed by bending the second side plate inward.

[0014] Optionally, the reflector includes a top plate and side plates. The top plate includes a first top plate and a second top plate, and the side plates include a first side plate and a second side plate. One end of the first top plate and one end of the second top plate overlap.

The first top plate, the second top plate, the first side plate, and the second side plate surround at least a portion of the top and sides of the heater. The relative position of the first top plate and the second top plate is adjustable. And / or, the vertical position of the first side plate and the second side plate is adjustable.

[0015] Optionally, the bottom of the first side plate and the second side plate each have a bent portion that bends toward the heater; the reflector further includes a first extension plate and a second extension plate; the first extension plate is connected to the outside of the bent portion at the bottom of the first side plate to lengthen the bent portion at the bottom of the first side plate; the second extension plate is connected to the outside of the bent portion at the bottom of the second side plate to lengthen the bent portion at the bottom of the second side plate; the length of the extension of the first extension plate to the bent portion at the bottom of the first side plate is adjustable; and / or, the length of the extension of the second extension plate to the bent portion at the bottom of the second side plate is adjustable.

[0018] This utility model provides an electric oven in which the heater is positioned above the grill rack to prevent grease from dripping onto the heater surface, reducing the difficulty of keeping the heater clean and reducing the risk of grease dripping onto the heater surface causing an open flame. A reflector is positioned above the heater and extends downward to surround at least a portion of both sides of the heater to limit the heat radiation range of the heater, reduce the temperature around the electric oven and the perceived temperature for customers, improve the customer's dining experience, and improve the heat energy utilization rate of the heater.

[0019] Furthermore, by placing the heater at the top of the grill and the exhaust vent at the bottom of the grill and arranging them circumferentially along the grill, this application can fully absorb the oil fumes generated by the food on the grill. Compared with traditional electric grills, the heater is placed above the grill and the exhaust vent is placed below the grill, avoiding the situation in traditional electric grills where the heater is placed below the grill, and the heat generated by the heater may be exhausted by the exhaust system before reaching the food. At the same time, the heater is placed above the grill and the exhaust vent is placed below the grill. When the exhaust system is running, it helps to promote the convection of hot air above the grill, allowing the hot air above the grill to pass through the food and then enter the exhaust system, increasing the contact area between the hot air and the food, making the heat distribution in the food area more uniform, improving the cooking effect, improving the utilization of the heat energy of the hot air near the heater, and improving the heat energy utilization rate.

[0020] Furthermore, this application places the heater above the grill, and the food placement area on the support above the heater can hold the food that needs to be kept warm, thus reducing the distance between the food and the heater and improving the heat preservation performance.

[0034] Figure 1 This is a schematic diagram of the overall structure of an electric oven according to an embodiment of the present invention. Figure 2 This is an exploded view of the overall structure of an electric oven according to an embodiment of the present invention. Figure 3 This is a side view of the overall structure of an electric oven according to an embodiment of the present invention; see also Figure 1 , Figure 2 and Figure 3 This utility model provides an electric oven, including an oven body 1, a heater 2, and a reflector 3; the oven body 1 is provided with a grill rack 4, and the heater 2 is located above the grill rack 4; the reflector 3 is located above the heater 2, and the reflector 3 extends downward to surround at least a portion of both sides of the heater 2 to limit the heat radiation range of the heater 2.

[0035] In this embodiment, the oven body 1 is provided with a grill rack 4 for placing skewers and other ingredients to be grilled; the heater 2 is located above the grill rack 4, optimizing the overall structure of the traditional electric oven. Without changing the position of the ingredients, the heater 2 is placed above the grill rack 4, radiating downwards to grill the ingredients, preventing grease or other fluids from dripping onto the surface of the heater 2 during the grilling process, reducing the difficulty of keeping the heater 2 hygienic and clean, and reducing the risk of grease dripping onto the surface of the high-temperature heater 2 and causing open flames during grilling; the reflector 3 is located above the heater 2, extending downwards circumferentially to surround at least a portion of both sides of the heater 2, at least partially enclosing the heater 2 to constrain and limit the heat radiation range of the heater 2, reducing the direct radiation of the heater 2's heat to the surrounding environment, and confining more of the heat energy within the grilling range, improving the utilization rate of the heat energy generated by the heater 2, and also reducing the perceived temperature of customers and users in the surrounding area that was originally within the direct heat radiation range of the heater 2, improving the customer's dining experience and improving the user's working condition.

[0036] In some embodiments, the heater 2 is a straight heating tube and is arranged perpendicular to the direction of the grilling skewers; it can also be changed to a straight heating tube or other irregularly shaped heating tube such as a U-shape while keeping the heating area unchanged.

[0037] In some embodiments, the oven body 1 further includes a support 11, which extends at least partially above the grill 4; the reflector 3 is connected to the support 11, and the heater 2 is located below the top reflective surface of the reflector 3; a food placement area is provided above the support 11.

[0038] In some embodiments, the ingredients can be placed directly on the ingredient placement position, for example, the ingredient placement position is formed on the upper surface of the support and the ingredients are placed directly on the ingredient placement position; or the ingredients can be placed on a tray or on an ingredient support frame, and the food support structure such as the tray or ingredient support frame is placed on the ingredient placement position.

[0039] In this embodiment, the support 11 extends at least partially above the grill 4 to fix the reflector 3, the tray and the heater 2, as well as to support other items installed or placed above the grill 4; the reflector 3 is connected to the support 11, and the heater 2 is located below the top reflective surface of the reflector 3 to cooperate with the reflector 3 to reflect and confine the heat energy to the food area on the grill 4. Figure 4 This is a schematic diagram of the food placement area in an electric oven according to an embodiment of the present invention. Figure 4The support 11 has a food placement area above it for placing raw or semi-cooked food or keeping cooked food warm. The heat energy of the heater 2 will be dissipated on the side of the reflector 3 away from the heater 2. Other cooking utensils can also be placed on the food placement area to make use of the heat energy dissipated on the side of the reflector 3 away from the heater 2 for grilling and cooking other types of food such as soup pots, making full use of the heat energy generated by the heater 2 and improving the heat energy utilization rate.

[0040] In some embodiments, the support 11 includes a column 111 and a lateral extension 112 connected to the column, the lateral extension 112 extending above the grill 4; wherein, the lateral extension 112 includes a first support side plate 113 and a second support side plate 114 disposed opposite to each other, and the reflector 3 is disposed between the first support side plate 113 and the second support side plate 114.

[0041] In this embodiment, the upright 111 of the support 11 is fixed to the oven body 1 or the ground to support the structure connected to the upright 111; the lateral extension 112 connected to the upright 111 extends to the top of the grill 4 to support the structure set or placed on the top of the grill 4; the lateral extension 112 includes a first support side plate 113 and a second support side plate 114 arranged opposite to each other, and a reflector 3 is disposed between the first support side plate 113 and the second support side plate 114; at the same time, a food placement position is formed between the first support side plate 113 and the second support side plate 114 for placing a tray or other cooking utensils or containers, or a food support rack, which may include skewers used for grilling meat or kebabs.

[0042] In some embodiments, the reflector 3, the bracket 11, the column 111, and the lateral extension 112 connected to the column 111 are designed separately and connected by screws or rivets to improve the flexibility of structural installation; if cost and overall weight are not a concern, the above structures can also be welded to form an integral structure.

[0043] In some embodiments, in order to reduce weight, weight-reducing holes may be made in the bracket 11 and / or the bracket side plate to reduce the weight of the electric oven.

[0044] In some embodiments, the bottom of the food placement area formed between the first support side plate 113 and the second support side plate 114 is a hollow structure, so that the heat energy escaping from the side of the reflector 3 facing away from the heater 2 can be directly absorbed by the food placed directly in the food placement area, or used by cookware, containers, food support racks, etc. for cooking or heat preservation, thereby improving the heat energy utilization rate and reducing the ineffective heat energy generated by the absorption of heat energy by other metal parts; the heater 2 is set above the grill 4 and is close to the food in the food placement area, so it can make full use of the heat energy escaping from the side of the reflector 3 facing away from the heater 2 for heat preservation, resulting in better heat preservation effect; at the same time, it saves other heating equipment, reduces the types of equipment needed by merchants and reduces equipment procurement costs; or the bottom of the food placement area is a non-hollow structure to prevent the heat energy escaping from the heater 2 from acting too much on the food, resulting in the food being heated for too long, causing the taste to deteriorate or become inedible; the choice of whether to use a food placement area with a hollow or non-hollow structure depends on the need for cooking, long-term heat preservation or short-term heat preservation of the food in the food placement area.

[0045] In some embodiments, the top of the first support side plate 113 and the second support side plate 114 are provided with a support structure 115 suitable for placing a tray.

[0046] In this embodiment, the support structure 115 at the top of the first support side plate 113 and the second support side plate 114 is used to place the tray and limit and fix the tray, container or cookware; at the same time, the first support side plate 113 and the second support side plate 114 can be used to support the clamping and fixing structure of the tray, container or cookware.

[0047] In some embodiments, the food placement area is provided with a tray 116, the interior of which includes a first functional area 117 and a second functional area 118, which are separated by a partition 119.

[0048] The first functional area of ​​the tray 116 can be used to hold raw, semi-cooked, or cooked food and keep it warm. The second functional area of ​​the tray 116 can be used for other types of cooking such as grilling, frying, or soup cooking. The first and second functional areas are separated by a partition 119 to prevent the mixing of different foods or the impact of splashes from different functional areas on surrounding foods. When there is a greater demand for cooking other foods, both the first and second functional areas can be used for cooking. When there is no demand for cooking other foods, both the first and second functional areas can be used to hold food.

[0049] In other embodiments, when there is no need for cooking or heat preservation in the food placement area, heat insulation accessories can be customized to shield the side of the reflector 3 facing away from the heater 2, reducing the heat loss from the side of the reflector 3 facing away from the heater 2; or the distance between the items placed in the food placement area and the reflector 3 can be adjusted to reduce the impact of the heat loss from the side of the reflector 3 facing away from the heater 2 on the food.

[0050] In some embodiments, the electric oven further includes an exhaust system 5, which includes an exhaust port 51, an air duct 52, and an exhaust port 53. The exhaust port 51 is located below the grill 4 and is arranged around the grill 4. The exhaust port 53 is located at the bottom of the oven body 1 and is connected to the exhaust port 51 through the air duct 52.

[0051] In this embodiment, the exhaust vent 51 of the ventilation system 5 is located below the grill 4 and arranged around the circumference of the grill 4 to fully absorb the oil fumes generated by the food around the grill 4. Compared with traditional electric ovens, the heater 2 is located above the grill 4 and the exhaust vent 51 is located below the grill 4. This avoids the situation in traditional electric ovens where the heater 2 is located below the grill 4, and the heat generated by the heater 2 may be exhausted by the ventilation system 5 before it reaches the food. At the same time, with the heater 2 above the grill 4 and the exhaust vent 51 below the grill 4, when the ventilation system 5 is running, it helps to drive the convection of the hot air above the grill 4, allowing the hot air above the grill 4 to pass through the food and then enter the ventilation system 5. This increases the contact area between the hot air and the food, making the heat distribution in the food area more uniform, improving the cooking effect, increasing the utilization of the heat energy of the hot air near the heater 2, and improving the heat energy utilization rate.

[0052] In some embodiments, the electric oven further includes a water tank 13, the upper opening of which is located below the grill 4 and corresponds vertically to the grill 4; the air duct 52 is located outside the water tank 13 and is arranged adjacent to the water tank 13.

[0053] In this embodiment, external water is introduced into the water tank 6 through the inlet 61 and discharged through the outlet 62, realizing water circulation within the water tank 61. The upper opening of the water tank 6 is located below the grill 4 and corresponds vertically to the grill 4 to collect the fluid dripping from the food on the grill 4. The air duct 52 is located outside the water tank 6 and adjacent to it, and is connected to the exhaust vent 51 to cool the hot air in the air duct 52 using the water tank 6, while improving the integration of the exhaust system 5 and the water tank 6 and reducing the overall structural volume of the electric oven. The air outlet 53 is located at the bottom of the oven body 1 and is connected to the air duct 52 to exhaust the cooled air.

[0054] In some embodiments, the exhaust system 5 and the water tank 6 are nested together. The air duct 52 of the exhaust system 5 is nested outside the water tank 6. The air duct 52 uses the side wall of the water tank 6 as the inner wall of the air duct 52. The outer wall of the air duct 52 wraps around the side wall of the water tank 6 and forms a cavity between the side wall and the side wall. This does not affect the sealing design of the water tank 6, and at the same time improves the integration of the exhaust system 5 and the water tank 6.

[0055] In some embodiments, the air outlet 53 of the exhaust system 5 can be connected to the active exhaust device of the store through an external pipeline, and the electric oven exhaust system 5 can be switched on and off and the air volume can be adjusted by starting and stopping the store's exhaust device and controlling its power.

[0056] See Figure 3 In some embodiments, the reflector 3 is an integrated bending structure; processing the reflector 3 into an integrated bending structure facilitates processing and installation, and avoids changes in the position or structure of the reflector 3 and the range of heat radiation constrained by the fixed structure during long-term use, thereby reducing the heat energy utilization rate of the heater 2.

[0057] In some embodiments, the reflector 3 includes a top plate 31 and a side plate 32. The side plate 32 includes a first side plate 321 and a second side plate 322. The top plate 31 is disposed above the heater 2. The two ends of the top plate 31 are respectively connected to the downwardly extending first side plate 321 and second side plate 322. The top plate 31, the first side plate 321, and the second side plate 322 surround at least a portion of the top and sides of the heater 2. And / or, the reflector 3 further includes a first extension plate 33 and a second extension plate 34. The first extension plate 33 is formed by bending the first side plate 321 inward, and the second extension plate 34 is formed by bending the second side plate 322 inward. The top plate 31, the first side plate 321, the second side plate 322, the first extension plate 33, and the second side plate 322 are all connected to the heater 2. The second extension plate 34 forms a heat-reflecting surface on the side facing the heater 2. By forming a semi-enclosed structure of the heater 32 with the first side plate 321 and the second side plate 322 extending downward from both ends of the top plate 31, more of the heat energy generated by the heater 2 is reflected to the food area, improving the heat energy utilization rate. When the reflector 3 requires the first extension plate 33 and the second extension plate 34, a larger material can be selected to process the reflector 3. By forming the first extension plate 33 and the second extension plate 34 with the first side plate 321 and the second side plate 322, the bending angle and the length of the first extension plate 33 and the second extension plate 34 can be freely adjusted, making it convenient to use the reflector 3 to constrain the heat radiation range of the heater 2 as needed.

[0058] Figure 5 This is a side view of the overall structure of an electric oven according to another embodiment of the present invention. Figure 6 This is a side view of the reflector of an electric oven according to another embodiment of the present invention. Figure 7This is an exploded view of the reflector of an electric oven according to another embodiment of the present invention. Figure 8 This is an isometric schematic diagram of the reflector of an electric oven according to another embodiment of the present invention; see also Figure 5 , Figure 6 , Figure 7 and Figure 8 In other embodiments, the reflector 3 includes a top plate 31 and a side plate 32. The top plate 31 includes a first top plate 311 and a second top plate 312, and the side plate 32 includes a first side plate 321 and a second side plate 322. One end of the first top plate 311 and one end of the second top plate 312 overlap. The other end of the first top plate 311 is connected to the downwardly extending first side plate 321, and the other end of the second top plate 312 is connected to the downwardly extending second side plate 322. The first top plate 311, the second top plate 312, the first side plate 321, and the second side plate 322 surround at least a portion of the top and sides of the heater 2. The relative position of the first top plate 311 and the second top plate 312 is adjustable; and / or, the vertical position of the first side plate 321 and the second side plate 322 is adjustable.

[0059] The reflector 3 can be a split structure. The first top plate 311 and the second top plate 312 form a heat-reflecting surface facing the side wall of the heater 2, so that the heat energy generated by the heater 2 can be reflected to the required position. The top ends of the first top plate 311 and the second top plate 312 overlap, which facilitates the adjustment of the relative position between the first top plate 311 and the second top plate 312, so as to adjust the width of the reflector 3 and thus adjust the range of heat radiation generated by the heater 2.

[0060] The first side plate 321 and the second side plate 322 also form heat-reflecting surfaces facing the heater 2. The first side plate 321 and the second side plate 322 are respectively connected to the downward-extending ends of the sides of the first top plate 311 and the second side plate 322, so as to cooperate with the first top plate 311 and the second top plate 312 to form a heat-reflecting cavity that is closed at the top and sides and open at the bottom above the heater 2, so as to surround at least part of the top and sides of the heater 2. The heat-reflecting surfaces of the first top plate 311, the second top plate 312, the first side plate 321 and the second side plate 322 facing the heater 2 constrain the radiation range of the heat energy of the heater 2, reduce the evaporation radiation of the heater 2 on the side of the reflector 3, and adjust the heat energy of the heater 2 to the food area as much as possible, so that the same cooking effect can be achieved with lower heating power, reducing the electricity cost of the business.

[0061] The vertical positions of the first side plate 321 and the second side plate 322 are adjustable to adjust the height of the side wall of the reflector 3, so as to cooperate with the first top plate 311 and the second top plate 312 to adjust the width and / or height of the reflector 3, forming heat energy reflection cavities of different shapes and sizes, and changing the radiation range by reflecting and constraining the heat energy radiation direction of the heater 2.

[0062] In other embodiments, the first side plate 321 and the second side plate 322 can be fixed to the first top plate 311 and the second top plate 312 by means of elongated holes and bolts to realize the relative position adjustment function between the first side plate 321 and the first top plate 311, and the second side plate 322 and the second top plate 312.

[0063] In other embodiments, the bottom of the first side plate 321 and the second side plate 322 each have a bent portion that bends toward the heater; the reflector 3 further includes a first extension plate 33 and a second extension plate 34; the first extension plate 33 is connected to the outside of the bent portion at the bottom of the first side plate 321 to lengthen the bent portion at the bottom of the first side plate 321; the second extension plate 34 is connected to the outside of the bent portion at the bottom of the second side plate 322 to lengthen the bent portion at the bottom of the second side plate 322; the length of the extension of the first extension plate 33 to the bent portion at the bottom of the first side plate 321 is adjustable; and / or, the length of the extension of the second extension plate 34 to the bent portion at the bottom of the second side plate 322 is adjustable.

[0064] In this embodiment, the first extension plate 33 and the second extension plate 34 also form heat reflection surfaces on the sides facing the heater 2; the first extension plate 33 is connected to the outside of the bent portion at the bottom of the first side plate 321 so that the extension length of the bent portion at the bottom of the first side plate 321 in the bending direction is adjustable; the second extension plate 34 is connected to the outside of the bent portion at the bottom of the second side plate 322 so that the extension length of the bent portion at the bottom of the second side plate 322 in the bending direction is adjustable; the first extension plate 33, the first side plate 321 and the first top plate 311, and the second extension plate 34, the second side plate 322 and the second top plate 312, and the bending angles of the bent portions of the first side plate 321 and the second side plate 322 respectively bent toward the heater direction form heat reflection cavities of different shapes and sizes, thereby changing the radiation range by reflecting and constraining the heat radiation direction of the heater 2.

[0065] In some embodiments, the first extension plate 33 and the second extension plate 34 may also be connected to the side of the bent portion at the bottom of the first side plate 321 and the second side plate 322 facing the heater 2, so that the first extension plate 33 adjusts the length of the extended portion of the bent portion at the bottom of the first side plate 321 in the extended direction, and the second extension plate 34 adjusts the length of the extended portion of the bent portion at the bottom of the second side plate 322 in the extended direction.

[0066] In other embodiments, the first extension plate 33 is fixed to the first side plate 321 and the second extension plate 34 is fixed to the second side plate 322 through elongated holes, so that the extension length of the first extension plate 33 and the second extension plate 34 in the bending direction of the bent portion of the first side plate 321 and the second side plate 322 can be adjusted.

[0067] In other embodiments, the bent portions at the bottom of the first side plate 321 and the second side plate 322, which bend toward the interior of the heat reflection cavity, can have different bending angles. Various parts can be processed according to different bending angles, and the bending angle of the reflector 3 can be adjusted by replacing the first side plate 321 and / or the second side plate 322 with different bending angles.

[0068] In some embodiments, the reflector 3 is made of high-quality 8K stainless steel mirror panel for sheet metal processing, which enhances the reflective effect of the reflector 3 on the heat energy of the heater 2 to a greater extent, so that more heat energy is reflected to the food area instead of being absorbed by the metal parts.

[0069] The overall width, height, bending angle, and bending length of the reflector 3 can be freely adjusted within a certain range. The reflector 3 can be adjusted to different positions to achieve different constraints on the heat energy of the heater 2, so as to adapt to different baking requirements such as baking temperature, baking range, baking time, and heat preservation for different ingredients. The reflector 3 can be adjusted to the position required by the baking ingredients, improving the secondary utilization of the heat energy dissipated upward by the heater 2 and improving the heat energy utilization rate. In particular, with the cooperation of the first top plate 311, the second top plate 312, the first side plate 321, the second side plate 322, the first extension plate 33, and the second extension plate 34, the width, height, bending angle, and bending length of the reflector 3 can be adjusted, reducing the heating of the surrounding air, lowering the perceived temperature for customers, and providing a better experience.

[0070] In other embodiments, the installation height of the heater 2 is adjustable. By adjusting the installation height of the heater 2 and deriving the radiation path of the heat energy generated by the heater 2 in conjunction with the reflector 3, the optimal design parameters of the reflector 3, including width, height, bending angle, and bending length, are found. At the same time, the height design of the grill 4 position is combined to constrain the radiation range of the heat energy generated by the heater 2, ensuring that most of the heat energy generated by the heater 2 acts on the area of ​​the food being grilled, reducing the external dissipation of heat energy.

[0071] Figure 9 This is a schematic diagram showing the dimensions of the reflector of an electric oven according to an embodiment of the present invention. Figure 9In some embodiments, the proportional relationship formula is satisfied: α=(L2-L1)÷(2×L3); where L1 is the width of the lower opening of the reflector 3, L2 is the width of the upper opening of the grill 4, L3 is the height difference between the lower opening of the reflector 3 and the upper opening of the grill 4, and α is the proportional relationship between L1, L2 and L3, with α ranging from 0.4 to 0.6.

[0072] In this embodiment, the width of the lower opening of the reflector 3 is L1, the width of the upper opening of the grill 4 is L2, and the height difference between the lower opening of the reflector 3 and the upper opening of the grill 4 is L3. L1, L2, and L3 satisfy the proportional relationship: α = (L2 - L1) ÷ (2 × L3). When the first top plate 311, the second top plate 312, the first side plate 321, the second side plate 322, the first extension plate 33, and the second extension plate 34 of the reflector 3 are adjusted so that α is in the range of 0.4 to 0.6, the reflector 3 can reflect the heat energy generated by the heater 2 to the food area on the grill 4 as much as possible, reduce the heat energy generated by the heater 2 from dissipating to the surroundings, and maximize the utilization rate of the heat energy generated by the heater 2.

[0073] In some embodiments, the grill 4 further includes a frame and a drive device. The frame is provided with a food support frame for fixing food. The drive device drives the frame to move, and the frame drives the food support frame to rotate. Alternatively, the drive device directly drives the food support frame provided on the frame to rotate.

[0074] In this embodiment, a food support frame is used to fix the food. The food support frame is placed on the frame and fixed in place. The driving device moves the frame, thereby rotating the food support frame. Alternatively, the driving device directly rotates the food support frame to ensure that the food is heated evenly by the heater 2. It is understood that food can also be placed directly on the frame or skewered and fixed to the frame so that the driving device rotates the food to ensure even heating.

[0075] In some embodiments, the driving device may also be a reciprocating driving mechanism, connected to the frame to drive the frame to move the food reciprocally within the heating range formed by the heater 2 and the reflector 3 so that the food is heated evenly.

[0076] The rack can be equipped with one or more food placement positions. When the food is large, a food support rack can be used to secure it and place it on the placement position for grilling; when the food is small, it can be skewered and multiple skewers can be grilled simultaneously using multiple grilling positions.

[0077] In some embodiments, the electric oven also includes an oil collection box, which is positioned above the reflector 3 and below the food placement area to collect the liquids or grease from the food placed there. This prevents the liquids or grease from dripping directly onto the reflector 3, generating fumes and affecting the overall cleanliness and aesthetics of the electric oven. A certain gap is left between the oil collection box and the side of the reflector 3 facing away from the heater 2. This ensures effective collection of liquids or grease from the food and the cooking or heat preservation of the food, while also preventing the oil collection box from being too close to the reflector 3, which could cause the temperature inside the oil collection box to become too high and generate fumes.

[0078] It should be noted that, in this document, the directions such as up, down, horizontal, or vertical refer to the directions shown in the structural drawings of the specification. In practice, when the structures are rotated or flipped as needed, resulting in the up, down, horizontal, or vertical directions differing from the directions in the specification, the same rotation or flipping should be performed with reference to the directions shown in the structural drawings to achieve a unified structural observation coordinate system. In this document, relational terms such as "first" and "second" are used only to distinguish the first entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
