Description

Technical Field

[0001] The invention belongs to the field of egg frying machines, in particular to an automatic egg-turning and frying mechanism. Background Art

[0002] Omelette machines are very common in many catering industries, such as school canteens, and can meet people's huge demand for omelettes. Most omelette machines on the market have the following problems when in use:

[0003] 1. For example, in patent No. CN211270237U, a heating element is provided in the frying pan assembly, and an upper heating element is also provided directly above the frying pan assembly, so that the eggs in the frying pan are heated from above and below. The frying pan rotates 180 degrees, so that the eggs in the frying pan fall from the frying pan into the dinner plate directly below it. Since the frying pan is closed, the frying condition cannot be seen, and the time needs to be strictly controlled, otherwise the frying pan may age and affect the taste, or the surface may become burnt or mushy, thereby affecting the appearance and being unfavorable for sale;

[0004] 2. As shown in patent No. CN202010043338.0, when the eggs are cooked, the ejection motor is started to rotate the toothless gear, thereby driving the ejection block to move downward, thereby compressing the ejection spring. Because the toothless gear is missing teeth, when the toothless gear rotates to the toothless position, the ejection block will be released. Under the action of the ejection spring, the ejection block impacts the sliding condensation module, and then the eggs in the heating module are bounced up through the frying pan bracket, thereby achieving the effect of the eggs being out of the pan; the process of turning the eggs over and out of the pan requires more parts of the equipment, the assembly is complicated, and the many out-of-pan actions result in a longer time spent, and the efficiency of frying eggs is low. Summary of the invention

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figures 1 to 9 ;

[0025] For the sake of clarity, the directional terms "OX", "OY" and "OZ" are used here to distinguish the direction of movement of each part and the arc direction of the fried egg surface. Figure 1 The coordinate axes in .

[0026] Embodiment 1, as Figures 1 to 3 As shown, an automatic flipping frying egg mechanism comprises a fixed plate 1, an upper pot 2 and a lower pot 3 are fixedly provided above the fixed plate 1, the upper pot 2 and the lower pot 3 are provided with egg outlets, the egg outlet of the upper pot 2 is located above the lower pot 3, an upper spatula 4 is provided in the upper pot 2, and the upper spatula 4 is pushed to move the fried egg to the egg outlet, where it naturally falls and is flipped into the lower pot 3.

[0027] Specifically, a lower spatula 5 is provided in the lower pot 3, and a driving member 7 is provided on one side of the fixed plate 1. A sliding block 71 is slidably provided on one side of the driving member 7. The sliding block 71 is fixedly arranged with the upper spatula 4 and the lower spatula 5. The sliding block 71 is moved by the driving member 7, thereby driving the lower spatula 5 to push the fried egg out. Two driving members 7 can also be provided to drive the upper spatula 4 and the lower spatula 5 respectively. The driving member 7 independently controls the pushing of the upper spatula 4 and the lower spatula 5 on the fried eggs, and flexibly exchanges them, thereby controlling the time for the upper pot 2 and the lower pot 3 to fry the eggs, so as to meet the different requirements for the doneness of the two sides of the fried eggs.

[0028] The upper pot 2 and the lower pot 3 are provided with an egg frying surface 8. Since the egg frying surface 8 of the egg frying pan currently used is mostly flat-bottomed, and the fluidity of the oil is poor, when the oil is poured into the flat-bottomed egg frying surface 8, the oil cannot be evenly dispersed, which leads to uneven distribution of the oil on the egg frying surface 8. When the beaten egg falls on the oil-free area of ​​the egg frying surface 8, it will stick to the pan, and even cause the fried egg to be burnt, affecting the appearance. The egg frying surface 8 is arranged in a rectangular shape and forms a downwardly concave arc surface along the OX axis direction and the 0-Y axis direction. At the same time, the lower end surfaces of the upper spatula 4 and the lower spatula 5 are arranged in an arc shape so as to fit with the egg frying surface 8. When pushing the egg, it can be ensured that the surface of the fried egg is not broken, and the resulting fried egg is more complete.

[0029] Specifically, since the fried egg noodles 8 are arc-shaped (such as Figure 1 As shown in the figure, the upper spatula 4 and the lower spatula 5 need to adapt to the shape of the fried egg surface 8 during the process of pushing the eggs. The upper spatula 4 and the lower spatula 5 in this embodiment are made of high-temperature resistant silicone material, which can ensure that they can fit the frying pan surface 8 during the egg pushing process. In order to smoothly push the eggs and reset the upper spatula 4 and the lower spatula 5, a long hole 12 and a long hole 2 13 are provided on the fixed plate 1, an upper spatula plate 41 is fixedly provided above the upper spatula 4, and a lower spatula plate 51 is fixedly provided above the lower spatula 5; one side of the sliding block 71 is provided with two upper lifting avoidance devices 72 and lower lifting avoidance devices 73 (as shown in the figure) with the same structure. Figure 2 and Figure 3 The upper and lower lifting avoidance devices 72 and 73 are fixed in position; one end of the upper shovel plate 41 passes through the long hole 12 and is connected to the upper lifting avoidance device 72, and the other end is rotatably arranged with the sliding block 71; one end of the lower shovel plate 51 passes through the long hole 13 and is connected to the lower lifting avoidance device 73, and the other end is rotatably arranged with the sliding block 71; the sliding block 71 can drive the upper shovel plate 41 to make reciprocating motion in the long hole 12 and the lower shovel plate on the long hole 13 along the 0-X direction, and a spring 711 connected to the sliding block 71 is provided on one side of the upper lifting avoidance device 72, and the lower lifting avoidance device 73 is fixed in position; the upper shovel plate 41 passes through the long hole 12 and is connected to the lower lifting avoidance device 73, and the other end is rotatably arranged with the sliding block 71; the sliding block 71 can drive the upper shovel plate 41 to make reciprocating motion in the long hole 12 and the lower shovel plate on the long hole 13 along the 0-X direction, and a spring 711 connected to the sliding block 71 is provided on one side of the upper lifting avoidance device 72 A second spring 712 fixedly connected to the sliding block 71 is provided on one side of the device 73. When the sliding block 71 moves along the 0-X direction and drives the upper spatula 4 and the lower spatula 5 to push the egg along the curved surface of the egg-frying surface 8, the first spring 711 enables the upper spatula 4 to always maintain a counterclockwise rotating force, so that the lower end surface of the upper spatula 4 is always in close contact with the egg-frying surface 8 of the upper pan 2. Similarly, the second spring 712 enables the lower spatula 5 to always maintain a counterclockwise rotating force, so that the lower end surface of the lower spatula 5 is always in close contact with the egg-frying surface 8 of the lower pan 3. This ensures that the fried egg can be completely pushed out when pushing the fried egg, avoiding failure in shoveling the egg.

[0030] The upper spatula 4 rotates with the upper spatula plate 41 as the rotation point, and the lower spatula 5 rotates with the lower spatula plate 51 as the rotation point. The upper spatula 4 is rotated away from the fried egg surface 8 by the upper lifting avoidance device 72, and the lower spatula 5 is rotated away from the fried egg surface 8 by the lower lifting avoidance device 73, and the height between the lower end surface of the upper spatula 4 and the lower end surface of the lower spatula 5 and the fried egg surface 8 of the upper pan 2 and the fried egg surface 8 of the lower pan 3 is adjusted.

[0031] When the upper spatula 4 and the lower spatula 5 are in the process of resetting, the upper spatula plate 41 and the lower spatula plate 51 maintain the height between the upper spatula 4 and the lower spatula 5 and the upper pot 2 and the lower pot 3 through the upper lifting avoidance device 72 and the lower lifting avoidance device 73, so as to prevent the eggs in the upper pot 2 and the lower pot 3 from being contacted during the resetting process, resulting in scratching the eggs or pushing the eggs in the reverse direction; the lifting avoidance of the upper spatula 4 and the lower spatula 5 can also be provided by conventional technical means such as avoidance grooves, etc., as long as the lower spatula 5 can avoid the eggs in the lower pot 3 when resetting, and in this embodiment, since the upper lifting avoidance device 72 and the lower lifting avoidance device 73 have the same structure, the activity diagram of the upper lifting avoidance device 72 is taken as an example for explanation.

[0032] like Figure 4 As shown, the upper lifting avoidance device 72 includes a guide surface 1 729, an avoidance plate 721, a swing arm 722 and a spring piece 723. The avoidance plate 721 is provided with an avoidance groove 724, and an avoidance inclined surface 728 and a second notch 727 are provided between the avoidance groove 724 and the spring piece 723. A roller 725 is provided at one end of the swing arm 722, and a notch 1 726 can be formed between the avoidance inclined surface 728 and the spring piece 723. It should be noted that the spring piece 723 is elastic and deformable.

[0033] When stationary, the roller 725 is located at the upper end of the guide surface 1 729 of the notch 2 727. At this time, the lower end surface of the upper spatula 4 does not contact the frying surface of the upper pan 2, that is, it maintains a certain distance, ensuring that the upper spatula 4 does not contact the high-temperature frying surface 8 when waiting for the upper pan 2 to fry eggs, thereby greatly extending the service life of the lower spatula 5.

[0034] When the sliding block 71 starts to move along the 0-X direction, a track is formed between the avoidance groove 724 and the spring piece 723, and the roller 725 moves in the track. In this process, the tension of the spring 1 711 ensures that the lower end surface of the upper spatula 4 is always in contact with the arc-shaped egg-frying surface of the upper pot 2 and pushes the egg. When the roller 725 rolls over the avoidance inclined surface 728, the roller 725 presses down the spring piece 723 to form a gap 1 726 between the avoidance inclined surface 728 and the spring piece 723. The roller 725 continues to roll along the avoidance inclined surface 728 to expand the gap 1 726, so that the roller 725 can smoothly pass through the gap 1 726 until it reaches the lower end surface of the spring piece 723 and continues to move forward a certain distance, and is completely separated from the spring piece 723. In this process, the lower spatula 5 rotates counterclockwise with the upper spatula plate 41 as the rotation axis, raising the lower end surface of the lower spatula 5 so that the lower end surface of the lower spatula 5 is lifted away from the egg-frying surface 8 of the lower frying pan 3, completing the egg-shoveling action;

[0035] When the roller 725 sticks to the lower end surface of the spring piece 723 and rolls to the position of the second notch 727, the height of the lower end surface of the upper spatula 4 and the frying surface 8 is always maintained, which effectively avoids the egg in the upper pan 2 being pushed back during the resetting process, resulting in failure of frying the egg.

[0036] like Figure 1 As shown, the egg-frying surface 8 extends upward on both sides along the 0-Y direction to form a retaining wall 6, which can block most of the oil splashed during the frying process. The retaining walls 6 on both sides form a "U"-shaped opening 61. When the upper pan 2 finishes frying the eggs, the upper spatula 4 pushes them to the "U"-shaped opening 61 of the egg-frying surface 8, and they fall directly into the lower pan 4 below and turn over (as shown in FIG. Figure 8 As shown in the figure, since the upper spatula 4 and the lower spatula 5 move synchronously, there is no need to worry that the fried egg will fall on the lower spatula 5 when it falls.

[0037] like Figure 5 and Figure 6 As shown, when the upper spatula 4 and the lower spatula 5 push the fried egg from the frying surface 8 to the "U"-shaped opening 61, the oil pushed along with the fried egg will flow down from the "U"-shaped opening 61, and may directly flow to the bottom surfaces of the upper frying pan 2 and the lower frying pan 3. After a long period of accumulation, an oil scab will form on the bottom surface of the upper frying pan 2, and when it reaches a certain thickness and hardness, it will fall into the lower pan 5 below, causing the fried eggs to be unhygienic and affecting people's health. Therefore, the frying surface 8 is located at the "U"-shaped opening 61 and extends downward and rolls inward to form an oil guide portion 81. When the oil is pushed to the "U"-shaped opening 61 by the upper spatula 4 and the lower spatula 5, oil drops can be formed at the oil guide portion 81 and fall into the lower pan 3, thereby indirectly adding oil to the lower pan 3, reducing the amount of oil used while preventing the amount of oil in the fried eggs from being too much to affect the taste.

[0038] Specifically, in order to achieve stability in the entire flipping process and prevent the fried eggs from falling and accumulating in the lower pot 3 to form a lump, the hardness of the fried eggs and the speed at which the upper spatula 4 and the lower spatula 5 push the eggs out of the upper pot 2 and the lower pot 3 can be controlled by controlling the frying time. When the fried eggs are harder, the eggs can be pushed slowly, and when the fried eggs are softer (but the surface of the eggs must be solid), the eggs can be pushed quickly, thereby achieving the flipping of the fried eggs from the upper pot 2 to the lower pot 3. This process does not require human participation or too many complex mechanical structures to achieve, which saves labor costs while saving space for equipment installation and is simple to assemble.

[0039] like Figure 1 , Figure 2 , Figure 7 As shown, a heating tube hole 10 is provided on the upper pot 2, and a heating tube hole 10 is also provided on the lower pot 3. At the same time, a through hole 11 equal in size to the heating tube hole 10 and corresponding in position is provided on the fixing plate 1. A heating tube (not shown in the figure) is inserted into the two through holes 11 and placed in the heating tube hole 10. When oil is added from a of the upper pot 2, the heating tube (not shown in the figure) heats the egg-frying surface 8 of the upper pot 2 and the lower pot 3 at the same time to fry the eggs, thereby increasing the speed of frying the eggs and saving the time of frying the eggs. The temperature of the heating tube (not shown in the figure) is controlled to control the frying time of the eggs. The corresponding temperature can be adjusted according to different requirements for the doneness of the eggs, and the device has strong flexibility.

[0040] like Figure 7 As shown, the oil flows into the egg-frying surface 8 from the end a and passes through most of the area of ​​the egg-frying surface 8, and is evenly distributed on the egg-frying surface 8. Then, the eggs are beaten into the upper pan 2 so that the eggs can all be in contact with the oil, thereby avoiding the phenomenon of the eggs sticking to the pan, improving the effect of frying the eggs, making the frying eggs more beautiful, and thus increasing people's desire to buy.

[0041] When the upper spatula 4 pushes the fried egg to the "U"-shaped opening 61 and drops it downward, since the fried egg is still hot, frying will occur, and countless small drops of hot oil will fall onto the surfaces of surrounding parts, causing the equipment to be stained with oil, which may easily cause equipment failure to affect operation and be unhygienic. Therefore, when the fixed plate 1 fixedly supports the upper frying pan 2 and the lower frying pan 3, it can also block the fried oil from falling and contaminating the upper lifting avoidance device 72 and the lower lifting avoidance device 73, thereby protecting the normal operation of the equipment.

[0042] A receiving plate (not shown in the figure) is also provided below the "U"-shaped opening 61 of the lower pot 3, which can be used to catch the fried eggs in the lower pot 3. The lower spatula 5 pushes the fried eggs out of the "U"-shaped opening 61 of the lower pot 3 and drops them onto the receiving plate (not shown in the figure), and the whole egg-frying process is completed.

[0043] like Fig. 9As shown, the second embodiment is different from the first embodiment in that the fried egg surface 8 of the upper pot 2 and the lower pot 3 is disc-shaped, and the fried egg surface 8 forms a downwardly concave arc surface along the OX axis and the OY axis, and the fried egg surface 8 is open all around. The fried egg surface 8 can control the oil from overflowing and can fry the eggs into shape. At the same time, the fried egg surface 8 with a certain curvature along the OX axis and along the OY axis can make the eggs take the shape of a sun, which is more beautiful.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementations that can be understood by those skilled in the art.
