Description

Technical Field

[0001] This invention relates to the field of grills, and in particular to a grill assembly suitable for various kitchen appliances. Background Technology

[0002] An oven is a kitchen appliance that uses heat generated by electric heating elements or gas combustion to bake food; a steam oven is a modern kitchen appliance that combines steam and baking cooking methods. It can steam food, bake food using heating elements, or inject steam while baking; a microwave-steam-bake oven is a kitchen appliance that integrates microwave, steam, and baking functions.

[0003] An oven includes an inner cavity and a rack. The inner wall of the inner cavity has storage slots on both sides for the rack to move at both ends. When the rack is used in a microwave-steam-bake or steam-bake oven, after the microwave-steam-bake or steam-bake oven has finished cooking, the rack moves along the storage slots as it is removed from the inner cavity. Racks are generally made of metal, which has a high coefficient of friction. When the rack contacts the inner wall of the inner cavity and moves relative to it, friction occurs, which can easily cause sparking or scratch the coating on the inner cavity of steam-bake ovens. Therefore, this type of rack is difficult to use in microwave-steam-bake ovens and in coated steam-bake cavities, making its applicability limited. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a grill assembly applicable to a variety of kitchen appliances, thereby solving the problem of poor applicability of existing grills.

[0005] To solve the above-mentioned technical problems, the technical solution used in this utility model is as follows:

[0006] The present invention discloses a grill assembly suitable for various kitchen appliances, comprising a grill body, a connecting bracket, and a protective frame. The connecting bracket is disposed at the placement end of the grill body, and the protective frame is connected to the connecting bracket. The grill body and the protective frame are connected through the connecting bracket. The protective frame wraps around the outer wall of the placement end of the grill body and has the characteristics of high temperature resistance and high self-lubricating performance.

[0007] Preferably, the connecting bracket includes a buckle, which is disposed on the grill body, and the protective frame has a slot, with the buckle inserted into the slot.

[0008] Preferably, the protective frame is a high-temperature resistant plastic frame.

[0009] Preferably, both ends of the protective frame are bent toward the center of the grill body.

[0010] Preferably, the buckle is located at the bottom of the grill body, the slot is formed at the bottom of the protective frame, and after the buckle is inserted into the slot, the bottom surface of the buckle extends out of the bottom surface of the protective frame.

[0011] Preferably, the protective frame includes a base plate and a side plate. The side plate is disposed on the top surface of the base plate at an end away from the center of the grill body. A connecting part protrudes upward from the top surface of the base plate. There are multiple connecting parts, which are distributed along the extension direction of the base plate. The slot is formed through the top surface of the connecting part near the end of the side plate.

[0012] Preferably, a reinforcing rib is provided between two adjacent connecting parts.

[0013] Preferably, a first stop block is provided at the rear end of the top surface of the protective frame.

[0014] Preferably, a second stop block is provided at the rear end of the bottom surface of the protective frame.

[0015] Preferably, a first stop block is provided at the rear end of the top surface of the protective frame, and a second stop block is provided at the rear end of the bottom surface of the protective frame. The second stop block and the first stop block are distributed sequentially along the protective frame from the front end to the rear end.

[0016] The beneficial effects of this invention are as follows: During the process of placing or removing the grill rack into the storage cavity, the protective frame contacts the side wall of the inner liner. Compared to the case where the grill rack body contacts the inner liner, when the grill rack is used in a microwave-steam-grill product or a steam-grill product, after the microwave-steam-grill product or steam-grill product has finished operating, when the grill rack is removed from the storage cavity, the surface of the grill rack body is not smooth enough, and there may be some small protrusions, burrs, or unevenness on its surface. Friction will occur between the grill rack body and the inner side wall of the inner liner, making it easier to... In cases where sparking or scratching of the coating on the inner liner of a steam oven is possible, the protective frame of this product is made of a high-temperature resistant, self-lubricating material. Therefore, when the protective frame comes into contact with the inner liner of a microwave steam oven or a steam oven and relative movement occurs, the self-lubricating property of the protective frame can reduce friction, thereby reducing the occurrence of sparking or scratching of the coating. This allows the grill rack of this application to be used not only in ovens, but also in microwave steam ovens and steam ovens, thus improving the applicability of the grill rack.

[0028] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings.

[0029] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] refer to Figures 1-9 This invention provides a grill assembly suitable for various kitchen appliances, including a grill 1, which is placed inside an inner liner 2. The inner liner 2 has an opening on one side and a storage cavity 21 inside. The grill 1 is inserted into the storage cavity 21 through the opening of the inner liner 2, or removed from the storage cavity 21 through the opening of the inner liner 2. In this embodiment, when the openings of the inner liner 2 are placed facing each other, the opening is the front end, the side of the inner wall opposite the opening is the rear end, and the left and right sides of the inner wall are the inner sidewalls. Basic protrusions 22 protrude from the two inner sidewalls of the inner liner 2 into the storage cavity 21. The basic protrusions 22 extend along the front of the inner liner 2... Extending in the rear direction, the number of basic protrusions 22 depends on the specific situation. In this embodiment, each inner sidewall is provided with three basic protrusions 22 arranged vertically. The basic protrusions 22 on the two inner sidewalls correspond one to one. The two corresponding basic protrusions 22 are located on the same horizontal plane. A placement groove 23 is formed between two adjacent basic protrusions 22 on the same inner sidewall. A placement groove 23 is also formed between the basic protrusion 22 at the top and the top surface of the sidewall of the inner liner 2. When the grill 1 is located in the storage cavity 21, the two ends of the grill 1 are placed on the top surface of the corresponding basic protrusions 22, and the ends of the grill 1 are located in the placement groove 23.

[0032] The grill 1 includes a grill body 11 and a connecting bracket 12. The grill body 11 is used to support food. The two ends of the grill body 11 are placed on the corresponding base protrusions 22. There are two connecting brackets 12, which are respectively set at the two placement ends of the grill body 11. The connecting bracket 12 includes a connecting plate 121 and a buckle 122. The top surface of the connecting plate 121 is welded to the bottom surface of one end of the grill body 11. The buckle 122 is fixed to the bottom surface of the connecting plate 121 at the end away from the center of the grill body 11. There are multiple buckles 122, which are distributed along the extension direction of the bottom surface of the connecting plate 121.

[0033] The grill 1 also includes a protective frame 13. There are two protective frames 13, and the two protective frames 13 are respectively connected to their corresponding connecting brackets 12. The two protective frames 13 respectively wrap around the two ends of the grill body 11. The protective frame 13 has the characteristics of high temperature resistance and high self-lubricating performance. In the embodiment of this application, the protective frame 13 is made of high temperature resistant plastic such as PPS (not limited to).

[0034] Therefore, during the process of placing or removing the grill rack 1 into or from the storage cavity 21, the protective frame 13 contacts the side wall of the inner liner 2. Compared to the situation where the grill rack body contacts the inner liner, when the grill rack is used in a microwave-steam-grill product or a steam-grill product, after the microwave-steam-grill product or steam-grill product has finished operating, during the process of removing the grill rack from the storage cavity, the surface of the grill rack body is not smooth enough, and there may be some small bumps, burrs, or unevenness on its surface. Friction will occur between the grill rack body and the inner side wall of the inner liner, which is more likely to cause sparking. Furthermore, the coating on the inner liner of a steam oven is easily scratched. However, the protective frame 13 of this product is made of a material with high temperature resistance and self-lubricating properties. Therefore, when the protective frame 13 comes into contact with the inner liner 2, and when the protective frame 13 comes into contact with the inner liner 2 of a microwave steam oven or a steam oven and generates relative movement, the self-lubricating properties of the protective frame 13 can reduce friction and reduce the occurrence of sparks or scratches on the coating. This allows the grill rack 1 of this application to be used not only in ovens, but also in microwave steam ovens and steam ovens, thereby improving the applicability of the grill rack 1.

[0035] The protective frame 13 includes a base plate 131 and a side plate 132. The side plate 132 is fixed to the top surface of the base plate 131 at the end away from the center of the grill body 11. The cross-section of the combination of the base plate 131 and the side plate 132 is "L" shaped. A connecting part 133 protrudes upward from the top surface of the base plate 131. The number of connecting parts 133 is adapted to the number of buckles 122. Multiple connecting parts 133 are distributed along the extension direction of the base plate 131, and the top surface of multiple connecting parts 133 is close to the side plate 132. One end of the 32 is provided with a slot 134, and the slot 134 corresponds to the buckle 122. Multiple buckles 122 are engaged with their corresponding slots 134. The buckles 122 are inserted into the slots 134 from the top surface of the base plate 131. The bottom surface of the connecting plate 121 abuts against the top surface of the base plate 131. The outer wall of one end of the grill body 11 abuts against the inner wall of the side plate 132, so that the base plate 131 and the side plate 132 wrap around one end of the grill body 11.

[0036] A reinforcing rib 135 is fixed between two adjacent connecting parts 133. The two ends of the reinforcing rib 135 are fixed to the middle of one side of the connecting part 133 that is close to it. The bottom surface of the reinforcing rib 135 is fixed to the top surface of the base plate 131. The top surface of the reinforcing rib 135 and the top surface of the connecting part 133 are on the same horizontal plane. Under the action of the reinforcing rib 135, the load of the grill body 11 is transferred to the base plate 131 through the connecting part 133 and the reinforcing rib 135. The reinforcing rib 135 can share the load of the grill body 11, reducing the possibility of deformation or damage to the connecting part 133 due to excessive stress. At the same time, it also makes the load of the grill body 11 more evenly distributed on the base plate 131, reducing the possibility of the load of the grill body 11 being concentrated on a local area of ​​the base plate 131, thereby reducing the possibility of deformation and damage to the base plate 131 due to excessive local stress.

[0037] The protective frame 13 is bent at both ends toward the center of the grill body 11, thereby wrapping the corners of the grill body 11. This protects the grill body 11 and further reduces the contact between the grill body 11 and the inner wall of the inner liner 2. When the protective frame 13 is subjected to front-to-back forces, the front and rear outer walls of the grill body 11 can support the protective frame 13, thereby distributing the force between the buckle 122 and the base plate 131 and reducing the possibility of damage to the buckle 122.

[0038] The inner liner 2 has two inner sidewalls that protrude into the storage cavity 21 with limiting protrusions 24. The limiting protrusions 24 are vertically arranged. The number of limiting protrusions 24 depends on the specific situation. In this embodiment, each inner sidewall is provided with three such limiting protrusions 24 arranged vertically. The limiting protrusions 24 on the two inner sidewalls are correspondingly arranged. The two limiting protrusions 24 located at the bottom on the same inner sidewall extend downward along the corresponding base protrusion 22. A limiting space is reserved between the bottom surface of the limiting protrusion 24 and the top surface of the base protrusion 22 located at its bottom. The limiting protrusions 24 are located in the area 100-200mm away from the opening of the inner liner 2.

[0039] The top surface of the base convex 22 has two upward protruding side ribs 25. The side ribs 25 provide support for placing the baking rack 1 or baking tray in the placement groove 23. One side of the two side ribs 25 forms a concave transition groove 26 with the top surface of the base convex 22. The bottom of the limiting convex 24 is aligned with the front end of the transition groove 26. The side of the side rib 25 near the center of the base convex 22 is an inclined surface, that is, the transition surface between the side rib 25 and the base convex 22 is an inclined surface. The inclined direction is that the side rib 25 is inclined downward towards the center of the base convex 22.

[0040] The bottom surface of the buckle 122 extends out of the bottom surface of the base plate 131, so that when the grill 1 is placed inside the inner pot 2, the buckles 122 at the front and rear ends are placed on the top surface of the corresponding side ribs 25. Compared with the prior art, where the end of the grill body is directly placed in the groove extending along the front and rear ends of the inner wall of the inner pot, the contact area between the grill body and the inner wall of the inner pot is larger. When the grill is used in a microwave-steam-grill product or a steam-grill product, after the microwave-steam-grill product or steam-grill product is finished, the grill body is more likely to rub against the inner wall of the inner pot during the pushing and pulling process, which may cause sparking or damage to the coating. In this application, the contact area between the buckle 122 and the base protrusion 22 is smaller. During the movement of the grill 1, the friction between the buckle 122 and the base protrusion 22 can be reduced, thereby reducing the possibility of damage to the base protrusion 22.

[0041] A first stop block 31 is fixed to the rear end of the top surface of the side plate 132, and a second stop block 32 is fixed to the rear end of the bottom surface of the bottom plate 131. The second stop block 32 and the first stop block 31 are distributed along the long side of the protective frame 13 from the front end to the rear end. The protrusion height of the first stop block 31 and the second stop block 32 and the depth of the transition groove 26 are determined according to specific circumstances. In the embodiment of this application, the protrusion height of the first stop block 31 is about 5mm, the protrusion height of the second stop block 32 is about 3mm, and the depth of the transition groove 26 is about 4mm (slightly deeper than the second stop block 32).

[0042] When it is necessary to place the grill rack 1 into the inner cavity 2 storage chamber 21, insert the rear end of the grill rack 1 from the opening, with both ends of the grill rack 1 located in the corresponding placement slots 23. Move the grill rack 1 along the placement slots 23 toward the rear end of the storage chamber 21. When the first stop block 31 moves to the side of the limiting protrusion 24, press the rear end of the grill rack 1 downward until the first stop block 31 can pass through the bottom of the limiting protrusion 24. Continue moving until the grill rack 1 is completely pushed into the storage chamber 21, and then place the grill rack 1 on the top surface of the side rib 25.

[0043] When the grill rack 1 needs to be removed, pull the grill rack 1 outward until the second stop block 32 contacts the side wall of the side rib 25 at the front end, generating a significant stopping force that stops the pulling action of the grill rack 1. At the same time, the top surface of the first stop block 31 abuts against the bottom surface of the limiting protrusion 24, at which point a downward force is applied to the front end of the grill rack 1, causing the grill rack 1 to generate an overturning moment. At this time, the first stop block 31 contacts the support position of the limiting protrusion 24 and compresses it, generating a counter-moment to counteract the overturning moment, preventing the grill rack 1 from overturning. This meets the requirements of GB / T4706.22-2024 for limiting the tilt angle and load-bearing capacity of the grill rack at the stop position.

[0044] As the grill rack 1 is removed, the second stop block 32 abuts against the side wall of the side rib 25 at the front end, applying an upward force to the front end of the grill rack 1, causing the grill rack 1 to tilt downward from the front end to the rear end. At this time, the bottom surface of the second stop block 32 exceeds the top surface of the side rib 25 at the front end, and the top surface of the first stop block 31 moves away from the bottom surface of the limiting protrusion 24. Then, an outward pulling force is applied, causing the second stop block 32 to move to the top surface of the side rib 25, and the first stop block 31 to pass over the limiting protrusion 24. The grill rack 1 is then restored to the horizontal position, and the grill rack 1 is completely removed.

[0045] Compared to existing technologies where the rear end of the grill rack is arched to form a bend, which increases the requirements of the manufacturing process and thus increases the production cost, this application does not involve bending the grill rack body 11. Instead, it uses a connecting bracket 12 to connect the grill rack body 11 to the protective frame 13, thus meeting the requirement of the oven having a stop position. The manufacturing process of the connecting bracket 12 and the protective frame 13 is simpler, reducing the production cost of the grill rack 1. Furthermore, the protective frame 13 can reduce the possibility of sparking or coating damage between the grill rack 1 and the inner liner 2, allowing the grill rack 1 of this application to be used in microwave-steam-grill products and steam-grill products, thus improving the applicability of the grill rack 1.

[0046] The inner wall of the inner liner 2 is stretched into the storage cavity 21 with limiting ribs 27. The limiting ribs 27 are designed vertically and are located at the rear end of the basic protrusion 22. The top surface of the limiting ribs 27 is on the same horizontal plane as the top surface of the limiting protrusion 24 located at the top. The limiting ribs 27 extend downward to the rear end of the bottom basic protrusion 22. The limiting ribs 27 are connected to one end of the three basic protrusions 22 at the same time. The limiting ribs 27 and the three basic protrusions 22 are stretched as a whole.

[0047] With the help of the limiting rib 27, the problem of the inner wall of the inner liner 2 opening outward due to insufficient strength when the grill rack 1 and grill pan are under load can be effectively solved. In the prior art, there is no stopping position at the rear end of the inner liner 2 when the grill pan and grill rack 1 are put in. The grill pan and grill rack 1 can be pushed directly to the bottom and close to the hot air hood, which makes it easy to overheat when cooking food. In this application, the limiting rib 27 can limit the maximum stroke of the grill pan and grill rack 1 when pushed in. The limiting rib 27 can prevent the grill pan and grill rack 1 from getting close to the hot air hood, thereby reducing the situation of easy overheating when cooking food.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
