DETAILED DESCRIPTION

[0035] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0036] like Figure 6 As shown, direction 1 DIR1 represents the length direction; direction 2 DIR2 represents the width direction; it is easy to understand. Figure 6The direction perpendicular to the paper surface is the height direction.

[0037] As a specific embodiment, the electric fire oven of the embodiment of the utility model includes an electric heating device 1, a fire focusing plate 2, a lifting device 3 and an oven carrier 8.

[0038] The electric heating device 1 includes an electric heating element 11 and a circuit board 12 provided with an electric component 121; the electric heating element 11 includes an electric output head 111 and an electric connecting rod 112 fixedly and electrically connected to the electric output head 111, and the electric connecting rod 112 is fixedly and electrically connected to the circuit board 12, for example, a welding head or a connecting head (not shown in the drawings) is provided on the bottom end surface of the circuit board 12, and the bottom end of the electric connecting rod 112 passes through the welding head connected to the circuit board 12 and is welded or connected and fixed to the bottom end surface of the circuit board 12. For the same electric heating element 11, it is easy to understand that its size, material, etc. are the same. For the embodiment described later in which each electric output head 111 is located at the same horizontal plane height, it is possible to more conveniently control the size of the bottom end of the electric connecting rod 112 exposed from the bottom end surface of the circuit board 12, which is convenient for batch processing of the electric heating device 1 and can improve the yield rate. The electric connecting rod 112 is made of conductive material. The circuit board 12 and the electrical components 121 disposed thereon are conventional technologies, and can output a voltage sufficient to form an arc to the electrical output head 111 through the electrical connecting rod 112 .

[0039] The lifting device 3 is connected to the oven carrier 8 and grounded. For example, the lifting device 3 is fixedly connected to the oven carrier 8 by means of screw fastening, bonding, etc., and the lifting device 3 is grounded by connecting to the ground wire of the power cord (not shown in the drawing).

[0040] The fire gathering plate 2 and the lifting device 3 are both conductive and are electrically connected to the lifting device 3. For example, the fire gathering plate 2 and the lifting device 3 are an integrated structure (i.e., the two are one component) to achieve electrical connection between the two. Typically, the fire gathering plate 2 is provided with a fire gathering plate handle 29 and a heat insulating sleeve 291 surrounding the fire gathering plate handle 29.

[0041] The bottom end surface of the fire gathering plate 2 is a plane, and the electrical output head 111 is located below the fire gathering plate 2 with a gap between the electrical output head 111 and the fire gathering plate 2 .

[0042] The working principle is that the circuit board 12 outputs a voltage sufficient to form an arc to the electrical output head 111, so that an arc is formed between the electrical output head 111 and the fire gathering plate 2, which can realize electric fire heating of the fire gathering plate 2 and achieve the frying and grilling function.

[0043] As one of the specific implementations, there are multiple electric heating elements 11, and each electric output head 111 is located at the same horizontal plane height. The distance between each electric output head 111 and the fire gathering plate 2 is equal, which can ensure that an arc is stably formed between each electric output head 111 and the fire gathering plate 2 and ensure that the heating power of the fire gathering plate 2 is stable.

[0044] As one of the specific implementations, the electric heating device 1 further includes an insulating plate 13 located between the electric output head 111 and the circuit board 12, and the electric connecting rod 112 passes through the insulating plate 13. Usually, the insulating plate 13 is made of insulating materials such as plastic and rubber. The safety and reliability of the electric heating device 1 can be improved (reducing the heat transmitted to the circuit board 12).

[0045] As one of the specific embodiments, the electric heating device 1 further includes an air driving device 18, and the position of the air driving device 18 is fixed relative to the circuit board 12, for example, the air driving device 18 is fixed on the insulating plate 13, and of course, it can also be fixed on the circuit board 12 or the oven carrier 8. The air driving device 18 can output air roughly parallel to the circuit board 12. For example, the air driving device 18 is a centrifugal fan and is close to the edge of the circuit board 12, and its output air outlet is parallel to the circuit board 12 and faces the inside of the circuit board 12. The reliability of the electric heating device 1 can be further improved.

[0046] As one of the specific embodiments, the side wall of the oven carrier 8 is provided with an air vent 82, and / or the bottom end surface of the oven carrier 8 is provided with an air vent 82 and a bottom foot pad 89. The air vent 82 can be an air outlet or an air inlet, which can reduce the temperature inside the oven carrier 8 and improve reliability.

[0047] As one of the specific implementations, an air guide wall 821 is provided outside the air port 82. For example, when the air port on the side wall of the oven carrier 8 is used as an air outlet, the air guide wall 821 guides the air output from the air outlet downward, which can prevent the hot air from diffusing horizontally and causing discomfort to the user.

[0048] As one of the specific embodiments, the electric heating device 1 further includes an insulating sleeve 14, which surrounds the side wall of the electric connecting rod 112. This can further improve the safety of electricity use. For example, the insulating sleeve 14 is in a cylindrical state, the electric connecting rod 112 fits through the insulating sleeve 14, and the bottom end of the insulating sleeve 14 fits with the insulating plate 13. This can improve the fixing strength of the electric heating element 11.

[0049] As one of the specific implementations, the insulating sleeve 14 is made of ceramic, rubber or plastic.

[0050] As one of the specific implementations, a metal isolation cover 129 is further included, and the isolation cover 129 surrounds the circuit board 12 and the electrical components 121. Usually, the isolation cover 129 is made of metal such as aluminum alloy, which can reduce the radiation of the circuit board 12 and the electrical components 121 to the outside world.

[0051] As one of the specific implementations, the fire gathering plate 2 is provided with a through hole 21, and the through hole 21 is completely misaligned with the electric output head 111 when viewed from above. In other words, there is no overlapping part between the through hole 21 and the electric output head 111 when viewed from above. The oil stains and the like generated by the food being fried or grilled on the fire gathering plate 2 (for example, frying is achieved by direct contact of the fire gathering plate 2 with the food, or grilling is achieved by a gap between the fire gathering plate 2 and the food) can avoid the electric output head 111 when dripping through the through hole 21, thereby reducing the risk of the oil stains and the like dripping onto the electric output head 111, and reducing the risk of the electric output head 111 being unable to generate an arc due to the adhesion of the oil stains and the like.

[0052] As one of the specific embodiments, the through hole 21 is a rhombus, a rectangle, or an ellipse as a whole when viewed from above, and there are differences in the length (dimension in the length direction) and the width (dimension in the width direction) of the through hole 21. For example, the through hole 21 is an ellipse when viewed from above, and the major axis of the ellipse is arranged along the width direction, and the minor axis of the ellipse is arranged along the length direction. The grease generated by the food grilled on the fire gathering plate 2 will converge toward the end of the through hole 21 with a larger dimension in the length and width (due to factors such as the surface tension of the grease) and then drip, such as converging toward the flatter end of the ellipse (i.e., the end where the major axis of the ellipse is located), which can further reduce the risk of grease dripping onto the electrical output head 111. It is easy to understand that those skilled in the art can easily think of making changes to rotate the through hole 21 in the horizontal plane on the basis of this embodiment (so that the through hole 21 originally has an angle in the length direction and the length direction).

[0053] As one of the specific implementations, the through hole 21 extends downward along its hole edge to form a through hole wall (not shown in the drawings). The through hole wall overlaps with the hole edge 411 of the electric heating element in the height direction, which can further reduce or even avoid the risk of oil stains dripping onto the electric output head 111.

[0054] As one of the specific embodiments, it also includes an oil receiving plate 4 provided with an electric heating element hole 41, the oil receiving plate 4 is located between the electric output head 111 and the circuit board 12, the electric connecting rod 112 passes through the electric heating element hole 41, and the oil receiving plate 4 is detachably connected to at least one of the circuit board 12, the fire collecting plate 2, the lifting device 3, the electric heating device 1, and the oven carrier 8. Usually, for the embodiment provided with an insulating plate 13, the height adjustment protrusion 421 described later is placed on the insulating plate 13 to achieve a detachable connection with the electric heating device 1. The oil stains generated by the food grilled on the fire collecting plate 2 drip onto the oil receiving plate 4 through the through hole 21, and the oil stains on the oil receiving plate 4 can be easily cleaned after the oil receiving plate 4 is removed.

[0055] As one of the specific implementations, the hole edge of the electric heating element hole 41 extends toward the fire collecting plate 2 to form the electric heating element hole edge 411. This can prevent oil stains and the like from dripping through the electric heating element hole 41.

[0056] As one of the specific implementations, an inclination angle 42 is set between the top surface of the oil receiving plate 4 and the horizontal plane. In other words, the top surface of the oil receiving plate 4 is inclined to have a higher part and a lower part. The oil on the oil receiving plate 4 will flow toward the lower part of its top surface, which is convenient for collecting and treating the oil.

[0057] As one of the specific implementations, the edge of the oil receiving plate 4 extends upward to form an oil receiving plate edge wall 44 .

[0058] As one of the specific implementations, the bottom end surface of the oil receiving plate 4 is provided with a height adjustment protrusion 421, and the height adjustment protrusion 421 abuts against the circuit board 12, the insulating board 13 or the circuit board 12 so that an inclination angle 42 is provided between the top end surface of the oil receiving plate 4 and the horizontal plane. When the inclination angle 42 is formed, the oil receiving plate 4 can be conveniently removed for cleaning.

[0059] As one of the specific embodiments, an oil receiving pan 49 is further included, and an oil outlet 43 is provided at the lower part of the oil receiving plate 4, and the oil outlet 43 is connected to the oil receiving pan 49. The oil and other dirt on the oil receiving plate 4 flows into the oil receiving pan 49 due to its own weight and is collected, so that the oil receiving plate 4 is easily cleaned.

[0060] As one of the specific embodiments, the oven carrier 8 is provided with an oil receiving pan groove 491 and an oil output slot 492 connected to the oil receiving pan groove 491. The top of the oil receiving pan 49 is open, the oil receiving pan 49 is located in the oil receiving pan groove 491, and the oil output slot 492 has a portion located in the top opening of the oil receiving pan 49 when viewed from above. The oil receiving pan 49 is integrated with the oven carrier 8, which is convenient for use. In other words, oil stains can flow from the lower part of the oil receiving plate 4 through the oil output slot 492 into the oil receiving pan 49.

[0061] As one of the specific implementations, the hole edge of the oil outlet 43 extends downward to form an oil outlet edge 431; the oil outlet edge 431 passes through the oil outlet slot 492 and is fixed relative to the oven carrier 8. For example, the insulating plate 13 is provided with a clearance hole 134, the insulating plate 13 is fixed relative to the oven carrier 8, and the oil outlet edge 431 fits with the inner wall of the clearance hole 134, so that the oil outlet edge 431 passes through the oil outlet slot 492 and is fixed relative to the oven carrier 8. It can ensure that the position of the oil receiving plate 4 is fixed, and then it can ensure that the electric heating element 11 and the electric heating element hole 41 are accurately positioned.

[0062] As one of the specific implementations, the lifting device 3 is frame-shaped, the fire collecting plate 2 is detachably connected to the lifting device 3 and covers the top opening of the lifting device 3, the electric output head 111 and the lifting device 3 have overlapping parts in the height direction, and the distance from the electric output head 111 to the bottom end surface of the fire collecting plate 2 is less than the distance to the inner wall of the lifting device 3. It is easy to understand that the top and bottom ends of the lifting device 3 are both open to form a frame shape. Under the premise of ensuring reliable formation of the arc, the fire collecting plate 2 can be easily removed from the lifting device 3, which is convenient for cleaning the fire collecting plate 2.

[0063] As one of the specific implementations, the cross section of the lifting device 3 (such as Figure 7 As shown, the cross section cut by the horizontal plane is rectangular as a whole and gradually shrinks or increases from bottom to top, so that the lifting device 3 is square-shaped as a whole. Of course, when the cross section of the lifting device 3 is circular or elliptical as a whole, the lifting device 3 is correspondingly truncated or elliptical as a whole. For the embodiment of gradually shrinking from bottom to top, it is convenient to set the window 39 described later to observe the working state of the electric heating element 11; for the embodiment of gradually increasing from bottom to top, it can prevent the oil stains dripping from the food taken from the fire-collecting plate 2 from falling on the side wall of the lifting device 3 and keep it clean.

[0064] As one of the specific embodiments, it also includes a partition plate 31, which is detachably connected to the lifting device 3, and there are multiple electric heating elements 11, which are respectively located on both sides of the partition plate 31. For example, the electric heating elements 11 are divided into three groups arranged along the length direction (such as Figure 3 As shown, the rectangular array of electric heating elements 11 is a group, and a partition plate 31 is provided between the two groups of electric heating elements 11, so there are two partition plates 31. The electric heating elements 11 are controlled to work separately through the circuit board 12, for example, the electric heating elements 11 in the middle group are controlled to work, and the electric heating elements 11 in the two side groups stop working. At this time, only the middle part of the fire gathering plate 2 corresponding to the electric heating elements 11 in the middle group needs to be heated to achieve frying and roasting, and the parts on both sides of the fire gathering plate 2 are not heated to achieve heat preservation, etc.; in addition, the partition plate 31 forms a more suitable (for example, smaller) space enclosed with the lifting device 3, which is conducive to the stability of the electric arc and the realization of stable fire. The partition plate 31 can reduce the transfer of heat and achieve the temperature difference of the fire gathering plate 2.

[0065] As one of the specific implementations, the partition plate 31 passes through the side wall of the lifting device 3 (ie, passes through the partition plate slot 311) and one end is exposed from the side wall of the lifting device 3. When all the electric heating elements 11 need to work, the partition plate 31 can be easily pulled out.

[0066] As one of the specific implementations, the front side of the oven carrier 8 is provided with electrical components (not shown in the drawings) electrically connected to the circuit board 12, such as a potentiometer, a switch, a display screen, etc. The rear end of the partition plate 31 is exposed from the side wall of the lifting device 3.

[0067] As one of the specific implementations, a light-transmitting window 39 is provided on the side wall of the lifting device 3. For example, the window 39 is made of heat-insulating glass. The working state of the electric output head 111 can be confirmed through the window 39. For the embodiment in which the cross section of the lifting device 3 gradually decreases from bottom to top, the working state of the electric output head 111 can be confirmed more conveniently through the window 39.

[0068] As used in this utility model, the terms: first, second, etc., do not indicate any order, quantity or importance, but are only used for distinction.

[0069] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.

[0070] For example, the terms indicating orientation or position used in the present invention, such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.

[0071] As used in the present invention, terms such as approximately, overall, approximately, and similar are limiting terms that indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of a dimension includes but is not limited to the national standard for dimensional tolerance.
