Description

Technical Field

[0001] This invention relates to the field of grills, and more particularly to an oven with a stop. Background Technology

[0002] An oven is a kitchen appliance that uses heat generated by electric heating elements or gas combustion to bake food. It uses both upper and lower heating elements to heat food evenly in hot air and is commonly used to bake cakes, bread, cookies, egg tarts and other Western-style pastries, or roast chicken, roast duck and other foods.

[0003] An oven includes a housing and a rack. The housing has a sandwich structure, consisting of an outer shell and an inner liner. The inner liner is located inside the outer shell, and the rack is placed inside the inner liner. For example, in the Chinese utility model patent CN209018493U, "An Oven with a Rack", the rear end of the rack's support edge is arched and has a bend. Correspondingly, the inner liner's side wall is equipped with a blocking part to reduce the rack's tilting and provide a stop. However, the bend in the rack increases the manufacturing process requirements, thereby increasing the production cost of the rack. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide an oven with a stop, which solves the problem of high production cost of existing oven racks.

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

[0006] The oven with a stop mechanism described in this utility model includes:

[0007] Inner liner: The inner liner has an opening on one side and a storage cavity inside. The two inner sidewalls of the inner liner have basic protrusions protruding into the storage cavity. The basic protrusions extend along the front-back direction of the inner liner. The inner sidewalls of the inner liner have limiting protrusions protruding into the storage cavity. The limiting protrusions are located at the top of the basic protrusions on the same inner sidewall. A limiting space is reserved between the limiting protrusions and the top surface of the basic protrusions located at its bottom. The top surfaces of the basic protrusions have side ribs protruding upwards at both ends.

[0008] Grill: A first stop block is provided at the rear end of the top surface of one end of the grill, and a second stop block is provided at the rear end of the bottom surface of the grill. The second stop block and the first stop block are distributed sequentially along the grill from the front end to the rear end. The second stop block cooperates with the inner wall of the side rib located at the front end to form a stop position. The first stop block cooperates with the limiting protrusion to play a role in preventing tipping.

[0009] Preferably, the side rib located at the front end is inclined on the side near the center of the foundation bulge, and the inclination direction is downward towards the center of the foundation bulge.

[0010] Preferably, the grill includes a grill body and a protective frame, the protective frame is wrapped around the outer wall of one end of the grill body, the first stop block is disposed at the rear end of the top surface of the protective frame, and the second stop block is disposed at the rear end of the bottom surface of the protective frame.

[0011] Preferably, the grill also includes a buckle, which is disposed on the grill body, and the protective frame has a slot, with the buckle inserted into the slot.

[0012] Preferably, the protective frame is a high-temperature resistant plastic frame.

[0013] Preferably, both ends of the protective frame are bent toward the center of the grill body.

[0014] 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.

[0015] Preferably, the inner wall of the inner liner extends into the storage cavity with a limiting rib, the limiting rib being vertically designed and located at the rear end of the basic protrusion.

[0016] 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.

[0017] Preferably, a reinforcing rib is provided between two adjacent connecting parts.

[0018] The beneficial effects of this invention are as follows: Compared with the prior art where the rear end of the grill rack is arched to form a bent section, the bending of the grill rack increases the requirements of the manufacturing process, thereby increasing the production cost of the grill rack. This application does not have a bending process for the grill rack body. By setting a connecting bracket and a protective frame on the grill rack body, the second stop block cooperates with the inner wall of the side rib located at the front end to form a stop position, and the first stop block cooperates with the limiting protrusion to play an anti-tipping role, which meets the requirement of the oven having a stop position. The manufacturing process of the connecting bracket and the protective frame is simpler and can reduce the production cost of the grill rack. Attached Figure Description

[0030] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings.

[0031] 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.

[0032] 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.

[0033] refer to Figures 1-9 This invention provides an oven with a stop, comprising an inner liner 2 and a rack 1. The inner liner 2 has an opening on one side and a storage cavity 21 inside. The rack 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 of the inner liner 2 is the front end, the side of the inner wall of the inner liner 2 opposite to the opening is the rear end, and the inner walls of the inner liner 2 located on the left and right sides are the inner sidewalls. The two inner sidewalls of the inner liner 2 have basic protrusions 22 protruding into the storage cavity 21. The basic protrusions 22 extend along the front-back direction of the inner liner 2. 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 inner liner 2 sidewall. 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.

[0034] 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.

[0035] 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).

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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).

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.
