Description

Technical Field

[0001] This utility model relates to the field of grilling technology, specifically a grill with a textured surface. Background Technology

[0002] A grill is a small kitchen appliance that uses electricity (or other energy sources) to convert into heat energy, which is then transferred to the grill pan via a heating element. This allows for various heat processing methods such as frying, grilling, baking, and roasting of food (e.g., meat, staple foods, vegetables). Its core function is to achieve a caramelized or thoroughly cooked surface through controlled temperature output. It is characterized by ease of operation, high heating efficiency, and easy cleaning, and is widely used in homes and small restaurants. However, a drawback is that the hinged connection between the upper and lower grill pans makes the upper pan prone to tipping downwards under its own weight, often requiring manual support from the user. Otherwise, flipping the upper baking pan to close the lower baking pan would cause significant impact on the lower baking pan and affect user operation, making it inconvenient to pick up or flip food. To address these shortcomings, existing technology (Chinese patent application number: 202321729691.X, authorized announcement date: 2023-12-29) discloses a grill with a locking function. The locking mechanism ensures the reliability of the upper baking pan assembly when rotated to the first position. Specifically, the locking mechanism, in conjunction with a limiting mechanism, supports the opened upper baking pan assembly, reducing the need for user assistance, especially during temporary flipping. Simultaneously, a reset mechanism automatically resets the locking mechanism during the flipping and closing process of the upper baking pan assembly, thus achieving automatic locking.

[0003] The aforementioned literature uses a combination of locking and limiting components to support the opened upper baking pan assembly, reducing the need for users to hold it. However, this locking structure is relatively weak against external forces such as impacts. Once the grill is subjected to a certain amount of vibration or collision, the locking and limiting components will shift relative to each other, causing it to unlock. At the same time, the grease produced during grilling will drip irregularly, contaminating the outer surface of the grill body, kitchen countertops, and even the floor, requiring frequent wiping and increasing the cleaning burden on users. Therefore, we propose that a grill with a textured surface can effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a grill with a textured surface to solve the problems mentioned in the background art. The locking structure of the existing grill has weak resistance to external impact, is easily unlocked due to vibration and collision, causing the upper grill plate to fall and creating a safety hazard. In addition, the oil produced during grilling drips irregularly, which will pollute the equipment and the surrounding environment and increase the cleaning burden.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A griddle with a surface texture, including a lower housing, an upper baking tray is installed on the upper surface of the lower housing, and an operation panel is provided on the front surface of the lower housing. An upper housing is connected above the lower housing, and an upper baking tray is installed at the bottom of the upper housing. A base is fixedly connected to the rear surface of the lower housing, and a heat-insulating handle is hinged between the two bases through a rotating shaft. A card slot is opened on the lower surface of the lower housing, and limiting blocks are fixedly arranged at equal intervals on the left and right sides of the inner wall of the card slot. An oil collecting box is connected below the lower housing, and fitting blocks are fixedly connected at equal intervals on the left and right sides of the oil collecting box. Tooth grooves are opened at equal angles in the base with respect to the center point of the rotating shaft. Accommodating grooves are opened at equal angles on the outer side of the rotating shaft, and a pawl is rotationally connected to the inner wall of the accommodating groove through a shaft. A return spring is installed between the end side surface of the pawl and the inner wall of the accommodating groove.

[0006] Preferably, the surface of the upper housing is provided with a chessboard texture. An oil outlet nozzle is provided at the middle position of the connecting area between the lower baking tray and the upper baking tray, and the oil outlet nozzle is respectively connected to the oil diversion paths of the lower baking tray and the upper baking tray. Both the lower baking tray and the upper baking tray are flat plate structures with raised stripes.

[0007] Preferably, the fitting block and the card slot are in a snap-fit connection. The four fitting blocks correspond to the positions of the four limiting blocks, and one side of the bottom of the fitting block and the top of the limiting block are both inclined. The inclined surfaces of the fitting block and the limiting block are in contact with each other.

[0008] Preferably, the upper housing is bolted and fixed inside the heat-insulating handle. The heat-insulating handle is arranged in a "匚" shape, and the heat-insulating handle is sleeved and fixed on the outer sides of the two rotating shafts.

[0009] Preferably, the pawl and the tooth groove are in a meshing connection. A threaded rod is connected to the rotating shaft through a bearing, and a movable plate is sleeved on the outer side of the threaded rod. A traction rope is connected between the pawl and the movable plate.

[0010] Preferably, the front end of the threaded rod extends out of the side surface of the rotating shaft, and the threaded rod and the movable plate are in a threaded connection. The movable plate is slidably arranged inside the rotating shaft.

[0011] Preferably, guide wheels are rotationally connected at equal angles in the rotating shaft with respect to the center point of the threaded rod. The traction rope is wound around the outer side of the guide wheel, and both ends of the traction rope are fixedly connected to the side surface of one end of the pawl and the side surface of the movable plate respectively.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The specific content of this griddle with a surface texture is as follows:

[0013] (1) The oil outlets and oil guide slopes preset on the upper and lower baking pans can guide the oil that seeps out of the food during frying to naturally converge and flow in a directional direction, precisely into the oil collection box at the bottom of the lower shell. This can achieve efficient separation of oil and food, on the one hand, avoid the oil from being repeatedly heated in the baking pan to produce oil fumes, reduce the generation of harmful substances, and ensure healthy cooking, and on the other hand, prevent oil from dripping irregularly and contaminating the equipment and countertop, greatly reducing the amount of subsequent cleaning work and improving ease of use.

[0014] (2) The grease collection box adopts a convenient disassembly and assembly design. No tools are needed when disassembling. Just pull the box to the right, and the inclined surface of the bottom fitting block can slide smoothly along the top of the limit block in the slot, easily get rid of the constraint, and quickly remove it to pour out the grease and clean it directly. The operation is simple and efficient. When installing, just align it with the slot and push it in to complete the fixation. It greatly simplifies the cleaning process and reduces the user's burden.

[0015] (3) When the upper shell is flipped open, the pawl of the base rotating shaft can retract and disengage from the tooth groove under the squeezing force, without hindering the opening and closing operation. When flipped to a preset angle such as 90° or 180°, the pawl can automatically reset and engage the tooth groove under the action of the return spring, realizing the automatic locking of the upper shell. This design can effectively prevent the upper shell from falling back due to external force or its own weight, completely eliminating the safety hazard of high temperature components falling. At the same time, it does not require the user to hold and fix it, freeing up their hands to facilitate the placement and operation of food, significantly improving the safety and convenience of use.

[0016] (4) The unlocking and closing operation is simplified. Only the threaded rod on one side of the machine body needs to be rotated to drive the movable plate to move horizontally. Then, the pawl is pulled by the traction rope to retract and disengage from the tooth groove, quickly releasing the upper housing lock. After unlocking, the operator can easily flip the upper housing back to its original position and close it. The whole process does not require complicated operation, reducing the threshold for use and improving the convenience and smoothness of equipment operation. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 The present invention provides the following technical solution: a grill with a surface texture;

[0027] Example 1: To address the issues of weak resistance to external impacts in the locking structure of existing grills, which are prone to unlocking due to vibration or collisions, causing the upper grill pan 5 to fall and creating a safety hazard, and the irregular dripping of grease from grilling polluting the equipment and surrounding environment and increasing cleaning burden, the following solution is disclosed. Please refer to the following for details. Figures 1-3 and Figures 5-7As shown in the figure, it includes a lower housing 1. An upper baking tray 3 is installed on the upper surface of the lower housing 1, and an operation panel 2 is arranged on the front surface of the lower housing 1. An upper housing 4 is connected above the lower housing 1, and an upper baking tray 5 is installed at the bottom of the upper housing 4. The surface of the upper housing 4 has a checkerboard texture. An oil outlet nozzle 19 is arranged at the middle position of the connection area between the lower baking tray 3 and the upper baking tray 5, and the oil outlet nozzle 19 is respectively connected to the grease diversion paths of the lower baking tray 3 and the upper baking tray 5. Both the lower baking tray 3 and the upper baking tray 5 are flat plate structures with raised stripes. A base 7 is fixedly connected to the back of the lower housing 1, and a heat insulation handle 6 is hinged between the two bases 7 through a rotating shaft 12. The upper housing 4 is bolted and fixed inside the heat insulation handle 6. The heat insulation handle 6 is arranged in a "匚" shape, and the heat insulation handle 6 is sleeved and fixed outside the two rotating shafts 12. Tooth grooves 13 are equiangularly opened inside the base 7 with respect to the center point of the rotating shaft 12. Accommodation grooves are equiangularly opened on the outside of the rotating shaft 12, and a pawl 14 is rotatably connected to the inner wall of the accommodation groove through a shaft. A return spring 15 is installed between the end side surface of the pawl 14 and the inner wall of the accommodation groove.

[0028] During use, the user holds the heat insulation handle 6 and pulls up the upper housing 4, rotates it 180° so that the upper baking tray 5 and the lower baking tray 3 are in a horizontal state. At this time, the user can place the ingredients on the upper baking tray 5 and the lower baking tray 3 respectively, and utilize the uniform heat transfer between the upper baking tray 5 and the lower baking tray 3 to make the ingredients heat evenly to achieve cooking. And the user can also directly put all the ingredients on the lower baking tray 3, then rotate the upper housing 4 to the top of the lower housing 1, so that the upper housing 1 and the lower housing 4 are closed together to form a sealed space for cooking operations. At the same time, when opening the upper housing 4 of the griddle, the rotating shaft 12 inside the base 7 rotates synchronously with the flipping of the upper housing 4. During the process, the pawl 14 on the rotating shaft 12 is subjected to a squeezing force and will contract and rotate into the preset accommodation groove, thus disengaging from the meshing state with the tooth groove 13, without hindering the opening of the upper housing 4. When the upper housing 4 is flipped to any preset opening angle (such as 90° or 180°), the squeezing force disappears, and the pawl 14 automatically resets and pops out under the driving of the elastic potential energy of the return spring 15, and re-engages precisely with the tooth groove 13 at the corresponding position on the rotating shaft 12, which can automatically lock the upper housing 4 in the opened state, effectively avoiding its accidental fall due to external force touch or its own gravity, eliminating the safety hazard brought by the fall of high-temperature components, and also eliminating the need for the user to hold and fix the upper housing 4 during the operation process, significantly improving the use convenience and safety.

[0029] Embodiment 2: Different from Embodiment 1, in this embodiment, by using the arranged oil outlet nozzle 19 and the grease collection box 9, efficient separation of grease and ingredients can be achieved, which not only avoids the repeated heating of grease in the baking tray to generate oil fumes, but also makes the subsequent cleaning more convenient. For specific reference Figures 2-5As shown, a slot 8 is provided on the lower surface of the lower housing 1, and a limiting block 10 is fixed at equal intervals on the left and right sides of the inner wall of the slot 8. A grease collection box 9 is connected to the lower part of the lower housing 1, and a bonding block 11 is fixedly connected at equal intervals on the left and right sides of the grease collection box 9. The bonding block 11 and the slot 8 are connected by a snap-fit ​​connection. The positions of the four bonding blocks 11 and the four limiting blocks 10 are corresponding, and the bottom of the bonding block 11 and the top of the limiting block 10 are inclined. The inclined surfaces of the bonding block 11 and the limiting block 10 are in contact.

[0030] Using the oil outlets 19 on the upper baking pan 5 and the lower baking pan 3, the oil that seeps out of the food during frying will naturally converge at the oil outlets 19 along the preset oil guiding slope of the baking pan. Then, it will be directed by the oil outlets 19 and accurately flow into the oil collection box 9 at the bottom of the lower shell 1, achieving efficient separation of oil and food. This avoids the oil from being repeatedly heated in the baking pan and producing oil fumes, and also makes subsequent cleaning easier. When it is necessary to remove the oil collection box 9, the user only needs to pull the oil collection box 9 to the right. The adhesive block 11 at the bottom of the oil collection box 9 will move horizontally with the box body, and its inclined surface at the bottom will... The grease collection box 9 can be easily removed by sliding smoothly to the right along the top of the limiting block 10 inside the slot 8, thus easily escaping the constraint of the limiting block 10. The entire process requires no tools, allowing for quick removal of the grease collection box 9. Afterward, the accumulated grease inside can be poured out and cleaned, greatly reducing the difficulty of cleaning. During installation, simply align the grease collection box 9 with the slot 8 and push it in to complete the installation. During this process, the adhesive block 11 on the grease collection box 9 will move to the top of the limiting block 10 as it is pushed in. With the help of the friction generated by the contact between the limiting block 10 and the adhesive block 11, the grease collection box 9 can be stably limited and firmly fixed.

[0031] Example 3: Unlike Example 2, this example uses forward rotation of the threaded rod 16 to quickly release the lock on the upper housing 4. See details... Figure 6 and Figure 7 As shown, the pawl 14 and the toothed groove 13 are meshed together. The internal bearing of the rotating shaft 12 is connected to a threaded rod 16, and a movable plate 17 is sleeved on the outside of the threaded rod 16. A traction rope 18 is connected between the pawl 14 and the movable plate 17. The front end of the threaded rod 16 extends out of the side of the rotating shaft 12, and the threaded rod 16 and the movable plate 17 are threaded together. The movable plate 17 is slidably disposed inside the rotating shaft 12. A guide wheel is rotatably connected inside the rotating shaft 12 about the center point of the threaded rod 16. The traction rope 18 is wound around the outside of the guide wheel, and the two ends of the traction rope 18 are fixedly connected to the side of one end of the pawl 14 and the side of the movable plate 17, respectively.

[0032] When unlocking and closing the grill, the user only needs to rotate the threaded rod 16 on one side of the rotating shaft 12 in the forward direction. The threaded rod 16 will simultaneously drive the connected movable plate 17 to move horizontally. During the movement of the movable plate 17, the traction rope 18 connected to it will pull the pawl 14, causing the pawl 14 to rotate and retract into the receiving groove, thereby disengaging from the meshing state with the tooth groove 13 and quickly releasing the lock on the upper housing 4. At this time, the operator can easily flip the upper housing 4 back to its original position and smoothly cover it on the lower housing 1 to complete the closing operation. When the threaded rod 16 is rotated in the reverse direction, the movable plate 17 resets and no longer pulls the traction rope 18, so that the pawl 14 rotates back to its original position under the elastic force of the reset spring 15 and meshes with the tooth groove 13 again.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
