The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] See Figures 1 to 3This utility model discloses a griddle, including a griddle body 100, a griddle surface 300, multiple heating units 200 and multiple temperature control devices. The number of heating units 200 and temperature control devices are equal and connected in a one-to-one correspondence. The griddle body 100 supports the griddle surface 300, multiple heating units 200 and multiple temperature control devices. The griddle surface 300 is disposed on multiple heating units 200. Multiple heating units 200 heat each area of ​​the griddle surface 300. The griddle surface 300 is used to contact and process food. Food can be processed by placing food on the griddle surface 300.

[0034] The oven body 100 is square in shape, with support feet at each of the four corners of the lower part. These four support feet allow the oven body 100 to be placed on the ground or other platforms. The height of the support feet is set according to the actual usage scenario, allowing the operator or chef to process food in a suitable standing or sitting posture.

[0035] Multiple heating units 200 are distributed along the left-right direction. Each heating unit 200 includes a base plate 210, a heat-insulating reflective pad 220, a first heating element 230, and a second heating element 240. The base plate 210 is connected to the furnace body 100, thereby fixing the entire heating unit 200 to the furnace body 100. The base plate 210 has a storage groove, in which the heat-insulating reflective pad 220 is disposed. The first heating element 230 and the second heating element 240 are both disposed on the heat-insulating reflective pad 220. The storage groove serves to store and position the heat-insulating reflective pad 220, the first heating element 230, and the second heating element 240. The first heating element 230 is in the shape of a bent tube, and the second heating element 240 is wound around the first heating element 230, so that the heating elements are evenly distributed on the heat-insulating reflective pad 220 or the base plate 210, meaning that each upward-facing area of ​​the heating unit 200 has a heating element.

[0036] A temperature control device is electrically connected to the first heating element 230 and the second heating element 240 of a heating unit 200. The temperature control device controls the power supply to the first heating element 230 and the second heating element 240, as well as the magnitude of the current, which means controlling the power of the first heating element 230 and the second heating element 240. When the first heating element 230 and the second heating element 240 generate heat, the upward-radiating heat is directly transferred to the cooking surface 300. The heat radiated upwards and outwards is reflected by the heat-insulating reflective pad 220, so that most of the heat is transferred to the cooking surface 300, which heats up, allowing food to be cooked. The greater the heat, the higher the temperature. By controlling the power / heat output of the first heating element 230 and the second heating element 240, the cooking temperature can be set and adjusted.

[0037] Each temperature control device controls each heating unit 200, activating the appropriate number of heating units 200 based on the amount of food. Food is placed on the cooking surface 300 in the corresponding area of ​​the activated heating unit 200. The heat-insulating reflective pad 220 reduces heat waste and loss, improving heat utilization and resulting in a low-energy-consumption griddle. Furthermore, each area of ​​the heating unit 200 has an electric heating element, ensuring sufficient heat for all areas of the heating unit 200 and the cooking surface 300, thus minimizing temperature differences and improving temperature uniformity.

[0038] It is conceivable that both the first heating element 230 and the second heating element 240 can be heating tubes or heating wires. The heat-insulating reflective pad 220 can be a U-shaped heat-insulating plate or an asbestos insulation layer. The furnace surface 300 is made of one of the following materials: aluminum alloy, stainless steel, graphite, silicone, and ceramic. The furnace surface 300 has a non-stick coating. The base plate 210 is detachably connected to the furnace body 100 for replacement and maintenance of the heating unit 200. The base plate 210 is made of high-temperature resistant materials such as metal or graphite, such as aluminum alloy or stainless steel.

[0039] See Figure 3 In some embodiments, baffles are provided at both the left and right ends of the base plate 210, and the base plate 210 and the two baffles form a storage groove. The two baffles limit the heat insulation reflective pad 220 on the base plate 210. No baffles are provided at the front and rear ends of the base plate 210, so that both ends of the storage groove are open, making it easy to scrape off any debris that falls on the base plate 210.

[0040] Of course, baffles can also be installed around the base plate 210 to form a square storage slot. The square storage slot limits the heat insulation reflective pad 220 in the front-back and left-right directions.

[0041] See Figure 3 In some embodiments, the heat-insulating reflective pad 220 has inclined portions at both its left and right ends, with the included angle between the two inclined portions pointing upwards. These two inclined portions reflect heat back to the area above the middle of the base plate 210 / heat-insulating reflective pad 220, that is, onto the furnace surface 300, reducing heat loss through the left and right sides of the heat-insulating reflective pad 220. The front and rear ends of the heat-insulating reflective pad 220 do not have inclined portions, creating openings at both ends to facilitate scraping off debris that falls onto the heat-insulating reflective pad 220.

[0042] Of course, inclined sections can also be provided around the heat insulation reflective pad 220 to form square grooves. The square grooves reflect heat in the front-back and left-right directions, further reducing heat loss.

[0043] See Figure 1 or Figure 2In some embodiments, when cooking food on the stove surface 300, waste oil and food scraps are generated. The stove body 100 is provided with a waste trough 400, which is located in front of the stove surface 300. The waste can be easily scraped into the waste trough 400 with a shovel. The waste trough 400 is used to collect the waste generated during food processing and then process the waste in a unified manner.

[0044] It is understandable that the furnace surface 300 is square, the waste trough 400 is long and narrow, the length of the waste trough 400 is equal to or not much different from the length of the furnace surface 300 in the left and right directions, and the waste trough 400 is aligned with the front end of the furnace surface 300.

[0045] See Figure 1 or Figure 2 In some embodiments, the furnace body 100 is provided with a drawer-type waste tray 500, which is located below the waste trough 400. The bottom of the waste trough 400 is provided with a slag discharge port 410, which is connected to the waste tray 500. Waste can be conveniently and quickly discharged into the waste tray 500 through the slag discharge port 410, and then the waste can be conveniently and quickly removed by moving the waste tray 500.

[0046] In some embodiments, protective plates 600 are provided on the left, right and rear sides of the stove surface 300. The protective plates 600 are used to block food and prevent it from falling from the left, right and rear sides of the stove surface 300. Of course, they can also prevent waste oil from splashing to the left, right and rear, because people or other materials are often standing or placed on the left, right and rear sides of the stove. This can prevent waste oil from splashing onto the people or other materials. At the same time, the protective plates 600 can block the view of the people standing there.

[0047] See Figure 1 or Figure 2 In some embodiments, the guard plate 600 on the left side of the cooktop 300 and the guard plate 600 on the right side of the cooktop 300 gradually rise from front to back. When cooking food, the operator is located in front of the cooktop and often prefers to place the food further away from themselves, that is, they prefer to place the food on the back of the cooktop 300. The gradual increase in the height of the guard plate 600 from front to back ensures the blocking effect of the guard plate 600 while also reducing the amount of material used for the guard plate 600.

[0048] See Figure 3 In some embodiments, the heating unit 200 further includes multiple limiting blocks 250. The limiting blocks 250 are provided with notches to limit the first heating element 230 / second heating element 240. The limiting blocks 250 limit the first heating element 230 / second heating element 240 to prevent the first heating element 230 / second heating element 240 from shifting on the base plate 210.

[0049] It is conceivable that the lower end of the limiting block 250 is connected to the base plate 210, the heat insulation reflective pad 220 is provided with a clearance hole, the upper end of the limiting block 250 passes through the clearance hole and extends to the top of the heat insulation reflective pad 220, the notch is above the heat insulation reflective pad 220, that is, both side walls of the notch are above the heat insulation reflective pad 220, and the two side walls of the notch tend to clamp the first heating element 230 / second heating element 240.

[0050] In some embodiments, the temperature control device includes a control board, an adjustment knob 700 and a temperature sensor, all electrically connected to the control board.

[0051] See Figure 1 or Figure 2 The adjustment knob 700 is located on the front side of the furnace body 100. Control information can be input to the control board through the adjustment knob 700. The control board controls the power-off, power-on and power-on of the first heating element 230 and the second heating element 240 and the magnitude of the power-on current according to the control information, thereby controlling the heat output and temperature of the first heating element 230 and the second heating element 240.

[0052] A temperature sensor is located next to the first heating element 230 and the second heating element 240. The temperature sensor is used to monitor the temperature of the heating unit 200 / furnace surface 300. The temperature sensor feeds back a temperature signal to the control board. When the temperature of the heating unit 200 / furnace surface 300 is too low or too high, the control board increases or decreases the current of the first heating element 230 and the second heating element 240 according to the temperature signal.

[0053] It is understood that the furnace body 100 is cuboid, and the terminals of the first heating element 230 and the second heating element 240 both pass through the heat insulation reflective pad (220) and the base plate (210), and the terminals of the first heating element 230 and the second heating element 240 both extend into the inner cavity of the furnace body 100. The control board is located in the inner cavity of the furnace body 100. The side wall of the furnace body 100 is provided with heat dissipation holes.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
