Description
Technical Field
[0001] This utility model relates to the field of cookware technology, and in particular to a grill cover and a grill. Background Technology
[0002] An outdoor grill is a piece of equipment used for outdoor cooking, typically for grilling, baking, or smoking food. It can be used in backyards, camping, picnics, and other settings, providing a wonderful outdoor dining experience. There are many types of outdoor grills, the most common being charcoal grills, gas grills, electric grills, and smokehouses.
[0003] See Figure 1 An outdoor grill typically includes a grill body 100 and an openable grill lid 200. When the grill lid 200 is in... Figure 1 When the oven is in the open position as shown, the user is generally in operation, processing the food on the oven body 100. The side of the oven lid 200 facing the user is generally roughly perpendicular to the oven body 100, so that the opening angle of the oven lid 200 is sufficient for user operation. However, the windward side of the oven lid 200 is relatively large, and the center of gravity of the oven lid 200 is relatively high. The center of gravity of the oven lid 200 is generally located at or above the center of its height. When the wind is strong, the oven lid 200 is easily blown over, causing it to suddenly cover the oven body 100, posing a safety hazard of hitting the user. Utility Model Content
[0004] One of the technical problems solved by this utility model is to provide an oven cover that can effectively solve the technical problem in the prior art where the open oven cover is easily blown over when the wind is strong.
[0005] The second technical problem solved by this utility model is to provide an oven that can effectively solve the technical problem in the prior art where the open oven lid is easily blown over when the wind is strong.
[0006] The first technical problem mentioned above is solved by the following technical solution:
[0007] An oven cover, configured to be mounted on the oven body, capable of opening or closing the grilling cavity of the oven body, characterized in that the oven cover comprises:
[0008] A fixed cover, which is configured to be fixedly installed on the oven body;
[0009] The movable cover assembly is capable of switching between an open state and a closed state, and includes a first movable cover and a second movable cover. The first movable cover is hinged to the fixed cover, and the second movable cover is hinged to the fixed cover and can be linked with the first movable cover to drive the first movable cover to open.
[0010] In the closed state, both the first movable cover and the second movable cover are unfolded relative to the fixed cover to close the grilling cavity;
[0011] In the open state, the fixed cover, the first movable cover, and the second movable cover are stacked in sequence, and the angle between the front side of the oven cover and the opening of the grilling cavity is an obtuse angle.
[0012] The oven cover described in this utility model has the following advantages compared with the prior art:
[0013] When the oven lid is in the open position, the fixed lid, the first movable lid, and the second movable lid are stacked in sequence. This makes the size of the oven lid relatively small in the vertical direction, and the center of gravity of the oven lid is lowered compared to the prior art. Its windward area is also reduced compared to the prior art. Thus, even when the wind is strong, the oven lid in the open position is difficult to be blown over, allowing the oven lid to remain stably open, thereby improving the safety performance of the oven.
[0014] Meanwhile, the angle between the front side of the oven lid and the opening of the grilling cavity is an obtuse angle, meaning the opening angle of the oven lid is also an obtuse angle. This allows the oven lid to open at a larger angle, making it easier for users to operate. Furthermore, compared to the oven lid in the open state in existing technologies, and compared to the hinge point between the oven lid and the oven body, the overall center of gravity of this oven lid is also shifted backward. This requires a greater force to flip the oven lid forward, and the oven lid is less likely to be blown over by the wind when it is open, allowing the oven lid to remain stably open and thus improving the safety performance of the oven.
[0015] In one embodiment, the first movable cover is provided with a first linkage member, and the second movable cover is provided with a second linkage member that can cooperate with the first linkage member. When the movable cover assembly switches from the open state to the closed state, the second movable cover can rotate until the second linkage member is connected to the first linkage member so that the second movable cover drives the first movable cover to rotate.
[0016] In one embodiment, the second linkage can be hooked and connected to or separated from the first linkage.
[0017] In one embodiment, the first movable cover is provided with a first limiting member, and the fixed cover is provided with a second limiting member that can be connected to or separated from the first limiting member. In the closed state, the first limiting member and the second limiting member abut against each other to limit the relative positions of the first movable cover and the fixed cover.
[0018] In one embodiment, the oven cover further includes a pivot that rotates through the movable cover assembly and the fixed cover assembly.
[0019] In one embodiment, the movable cover assembly is provided with an abutting and limiting part, which can abut against the fixed cover in the open state.
[0020] In one embodiment, the abutment limiting portion includes:
[0021] A first abutting limiting plate is disposed on the first movable cover. In the open state, the first abutting limiting plate abuts against the fixed cover to restrict the movement of the first movable cover.
[0022] A second abutting limiting plate is disposed on the second movable cover. In the open state, the second abutting limiting plate abuts against the first abutting limiting plate to restrict the movement of the second movable cover.
[0023] In one embodiment, the fixed cover includes:
[0024] The fixed cover portion is arc-shaped and is configured to extend along the length direction of the oven body and be fixedly installed on the oven body;
[0025] The fixed side is fan-shaped, and a fixed side is provided at both ends of the fixed cover. The arc end of the fixed side is fixedly connected to the end of the fixed cover, and the straight end of the fixed side is configured to be fixedly installed on the oven body.
[0026] In one embodiment, the movable cover assembly is movably connected to the top corner of the fixed side.
[0027] The second technical problem mentioned above is solved by the following technical solution:
[0028] An oven includes an oven body and an oven cover, wherein the oven cover is fixedly installed on the oven body.
[0029] The oven described in this utility model has the following advantages compared with the prior art:
[0030] The oven includes the oven lid described above.
[0031] When the oven lid is in the open position, the fixed lid, the first movable lid, and the second movable lid are stacked in sequence. This makes the size of the oven lid relatively small in the vertical direction, and the center of gravity of the oven lid is lowered compared to the prior art. Its windward area is also reduced compared to the prior art. Thus, even when the wind is strong, the oven lid in the open position is difficult to be blown over, allowing the oven lid to remain stably open, thereby improving the safety performance of the oven.
[0032] Meanwhile, the angle between the front side of the oven lid and the opening of the grilling cavity is an obtuse angle, meaning that the opening angle of the oven lid is also an obtuse angle. This allows the oven lid to open at a larger angle, making it more convenient for users to operate. On the other hand, compared to the oven lid in the open state in existing technologies, the overall center of gravity of this oven lid is also shifted backward. At this time, the force required to flip the oven lid forward is greater, and the oven lid in the open state is less likely to be blown over by the wind, allowing the oven lid to remain stably open, thereby improving the safety performance of the oven.

[0062] Example 1
[0063] See Figure 1 In existing technology, outdoor grills generally include a grill body 100 and an openable grill lid 200. The grill lid 200 is a one-piece molded structure. When the grill lid 200 is in the open state, the user is generally in the operating state. The side of the grill lid 200 facing the user is generally roughly perpendicular to the grill body 100. Figure 1The α angle in the figure represents the opening angle of the oven lid 200. Generally, the α angle ranges from 90° to 110°. Because the oven lid 200 needs to completely cover the grilling cavity of the oven body 100 when closed to allow the food to receive more heat, the overall size of the oven lid 200 is relatively large. Its vertical dimension is also large when open, resulting in a larger windward area and a relatively high center of gravity. In strong winds, the open oven lid 200 is easily blown over, potentially injuring the user and posing a safety hazard.
[0064] In order to improve the wind resistance of the oven lid and prevent it from being blown over by strong winds, thus affecting the user's safety, this embodiment provides an oven.
[0065] See Figures 2-4 In this embodiment, the oven includes an oven body 10, which includes a grilling cavity. The grilling cavity is provided with a grilling plate for heating food and a grilling rack for supporting food. The grilling plate is located below the grilling rack. The user places the food on the grilling rack, and the grilling plate heats up to grill the food.
[0066] Furthermore, in order to close the grilling cavity when needed to prevent excessive heat loss from the food during grilling, in this embodiment, the oven also includes an oven cover, which is configured to be installed on the oven body 10 of the oven and can open or close the grilling cavity of the oven body 10.
[0067] Specifically, in this embodiment, the oven cover includes a fixed cover body 1 and a movable cover body assembly 2.
[0068] The fixed cover 1 is configured to be fixedly installed on the oven body 10. Specifically, in this embodiment, the fixed cover 1 of the oven cover is fixedly installed on the oven body 10.
[0069] The movable cover assembly 2 is movably mounted on the fixed cover 1 and can switch between an open and closed state. See also Figure 2 In the closed state, the movable cover assembly 2 unfolds relative to the fixed cover 1 to seal the grill cavity. See also Figure 3 and Figure 4 In the open state, the movable cover assembly 2 and the fixed cover 1 are stacked to allow the grill cavity to be opened.
[0070] Specifically, the movable cover assembly 2 includes a first movable cover 21 and a second movable cover 22. The first movable cover 21 is hinged to the fixed cover 1, and the second movable cover 22 is hinged to the fixed cover 1 and can be linked with the first movable cover 21 to drive the first movable cover 21 to open.
[0071] In the closed state, the first movable cover 21 and the second movable cover 22 are both unfolded relative to the fixed cover 1 to close the barbecue cavity.
[0072] In the open state, the fixed cover 1, the first movable cover 21, and the second movable cover 22 are stacked in sequence, and the angle between the front side of the oven cover and the opening of the grill cavity is an obtuse angle.
[0073] In this embodiment, the oven cover is fixedly installed on the oven body 10, and the movable cover assembly 2 can move relative to the fixed cover 1 and switch between an open and closed state. When the user needs to process the food (such as observing, brushing with sauce, or flipping), the movable cover assembly 2 is switched to the open state, at which time the movable cover assembly 2 and the fixed cover 1 are stacked to open the grilling cavity. When it is necessary to control the oven temperature at a higher level, the movable cover assembly 2 is switched to the closed state, at which time the movable cover assembly 2 unfolds relative to the fixed cover 1, and the two together close the grilling cavity.
[0074] When the oven lid is in the open position, the movable lid assembly 2 and the fixed lid assembly 1 are in a neutral position. Figure 3 and Figure 4 As shown in the stacked state, the fixed cover 1, the first movable cover 21, and the second movable cover 22 are stacked in sequence, making the size of the oven cover relatively small in the vertical direction. The center of gravity of the oven cover is lowered compared to the prior art, and its windward area is also reduced compared to the prior art. Thus, even when the wind is strong, the oven cover in the open state is difficult to be blown over, allowing the oven cover to remain stably in the open state, thereby improving the safety performance of the oven.
[0075] Meanwhile, in the open state, the angle between the front side of the oven lid and the opening of the grilling cavity is an obtuse angle, meaning that the opening angle β of the oven lid is also an obtuse angle. This allows the oven lid to open at a larger angle, making it more convenient for users to operate. Furthermore, compared to the oven lid in the open state in existing technologies, and compared to the hinge point between the oven lid and the oven body, the overall center of gravity of this oven lid is also shifted backward. At this point, the force required to flip the oven lid forward is greater, and the oven lid in the open state is less likely to be blown over by the wind, allowing the oven lid to remain stably open and thus improving the safety performance of the oven.
[0076] It is understood that the front side of the oven lid in the open state is the surface of the movable lid assembly 2 facing the user. Specifically, in this embodiment, see... Figure 2In the closed state, the first movable cover 21 is located between the fixed cover 1 and the second movable cover 22. At this time, the fixed cover 1, the first movable cover 21, and the second movable cover 22 unfold sequentially to cover the grilling cavity of the oven body 10.
[0077] See Figure 3 and Figure 4 In the open state, the fixed cover 1, the first movable cover 21 and the second movable cover 22 are stacked in sequence, with the first movable cover 21 sandwiched between the fixed cover 1 and the second movable cover 22, thereby opening the grilling cavity of the oven body 10, making it convenient for users to process the food in the grilling cavity.
[0078] The front side of the oven lid when it is open is the surface of the second movable cover 22 facing the user.
[0079] Specifically, cover the oven with... Figure 3 The open state shown has been switched to Figure 2 When the oven is in the closed state, the user rotates the second movable cover 22, which is linked with the first movable cover 21 to close the first movable cover 21 (that is, the second movable cover 22 can open the first movable cover 21 during the process of switching to the open state), and finally the entire oven cover is switched to the closed state.
[0080] When the user needs to switch the oven lid from the closed state to the open state, the user first rotates the second movable cover 22. When the second movable cover 22 rotates to overlap with the first movable cover 21, the user simultaneously rotates the unfolded second movable cover 22 and the first movable cover 21, so that the fixed cover 1, the first movable cover 21 and the second movable cover 22 are stacked in sequence until the first movable cover 21 is sandwiched between the fixed cover 1 and the second movable cover 22.
[0081] See Figure 4 and Figure 5 In one embodiment, the oven lid further includes a rotating shaft 3, which rotatably passes through the movable lid assembly 2 and the fixed lid 1. This achieves a movable connection between the movable lid assembly 2 and the fixed lid 1.
[0082] Specifically, the oven lid can be switched between a closed and an open state by rotating the movable cover assembly 2.
[0083] Specifically, a limit cap is provided at one end of the rotating shaft 3, and the other end is passed through the movable cover assembly 2 and the fixed cover 1 in sequence. Then, an R-shaped pin is installed at the other end of the rotating shaft 3 to prevent the rotating shaft 3 from falling off.
[0084] In this embodiment, the movable cover assembly 2 is easy to disassemble. When it is necessary to clean the movable cover assembly 2, the R-pin is pulled out, and then the rotating shaft 3 is pulled out to detach the movable cover assembly 2, which makes it convenient to clean the movable cover assembly 2 after grilling.
[0085] Furthermore, in one embodiment, in order to achieve linkage between the second movable cover 22 and the first movable cover 21 to drive the first movable cover 21 to close, see [reference needed]. Figures 6-8 The first movable cover 21 is provided with a first linkage 211, and the second movable cover 22 is provided with a second linkage 221 that can cooperate with the first linkage 211. When the movable cover assembly 2 switches from the open state to the closed state, the second movable cover 22 can rotate until the second linkage 221 is connected to the first linkage 211 so that the second movable cover 22 drives the first movable cover 21 to rotate.
[0086] Specifically, see Figure 3 and Figure 4 To facilitate the operation of the movable cover assembly 2, a handle 4 is also provided on the second movable cover 22. The user can pull the second movable cover 22 by pulling the handle 4.
[0087] Furthermore, in one embodiment, see [link to relevant documentation]. Figures 7-12 The second linkage 221 can be hooked and connected to or separated from the first linkage 211. When the second linkage 221 is hooked and connected to the first linkage 211, the second movable cover 22 can drive the first movable cover 21 to rotate. When the second linkage 221 is separated from the first linkage 211, the rotation of the second movable cover 22 and the first movable cover 21 does not interfere with each other.
[0088] Specifically, in this embodiment, the first movable cover 21 and the second linkage 221 are both relatively thin cuboid pieces with simple structures, and the two can be hooked together.
[0089] Specifically, see Figures 7-12 Described from the perspective of the oven lid being open, the second movable lid 22 overlaps the outside of the first movable lid 21. The first linkage 211 is located at the end of the first movable lid 21 closer to the user, and the second linkage 221 is located at the end of the second movable lid 22 furthest from the user. When the user faces the closing direction (i.e., the direction closer to the user),... Figure 6When the second movable cover 22 is rotated (as shown in the first rotation direction), the second linkage 221 will rotate along the first rotation direction until it abuts against the first linkage 211. As the second movable cover 22 continues to rotate, the second linkage 221 will hook onto the first linkage 211, thereby causing the second movable cover 22 to drive the first movable cover 21 to rotate simultaneously along the first rotation direction, ultimately causing the oven lid to rotate to the closed state.
[0090] When the oven lid switches from the closed state to the open state, the second movable cover 22 rotates in the second rotation direction opposite to the first rotation direction. The second linkage 221 separates from the first linkage 211 first, so that the second movable cover 22 can rotate smoothly to the outside of the first movable cover 21. When the second movable cover 22 rotates to overlap the outside of the first movable cover 21, the second movable cover 22 and the first movable cover 21 continue to rotate in the second rotation direction at the same time, so that the second movable cover 22 and the first movable cover 21 both rotate to overlap the outside of the fixed cover 1. At this time, the fixed cover 1, the first movable cover 21 and the second movable cover 22 are stacked in sequence and the first movable cover 21 is sandwiched between the fixed cover 1 and the second movable cover 22. The oven lid is in the open state.
[0091] Optionally, the first linkage 211 can be integrally formed with the first movable cover 21, or it can be fixed to the first movable cover 21 by welding.
[0092] The number of first linkage components 211 is preferably multiple, and the first linkage component 211 and the second linkage component 221 are set in a one-to-one correspondence.
[0093] Optionally, the second linkage 221 can be integrally formed with the second movable cover 22, or it can be fixed to the second movable cover 22 by welding.
[0094] In one embodiment, the movable cover assembly 2 is provided with an abutting and limiting part, which can abut against the fixed cover 1 in the open state. This arrangement ensures that when the oven lid is in the open state, the abutting and limiting part abuts against the fixed cover 1, so that the movable cover assembly 2 can be maintained in a preset position, thereby ensuring that the oven lid is stably in the open state.
[0095] Specifically, participate in Figure 6 and Figure 7 In this embodiment, the abutting and limiting part includes a first abutting and limiting plate 213 and a second abutting and limiting plate 222.
[0096] The first abutting limiting plate 213 is disposed on the first movable cover 21. In the open state, the first abutting limiting plate 213 abuts against the fixed cover 1 to restrict the movement of the first movable cover 21.
[0097] The second abutment limiting plate 222 is disposed on the second movable cover 22. In the open state, the second abutment limiting plate 222 abuts against the first abutment limiting plate 213 to restrict the movement of the second movable cover 22.
[0098] That is, in the open state, the first abutting limit plate 213 abuts against the fixed cover 1 to prevent the first movable cover 21 from continuing to slide downward; the second abutting limit plate 222 abuts against the first abutting limit plate 213 to restrict the second movable cover 22 from continuing to slide downward.
[0099] Furthermore, in one embodiment, in order to ensure that the first movable cover 21 remains stably closed and does not continue to rotate under its own weight when the oven lid is in the closed state, see [reference needed]. Figure 6 , Figure 7 , Figure 13 and Figure 14 The first movable cover 21 is provided with a first limiting member 212, and the fixed cover 1 is provided with a second limiting member 111 that can be connected to or separated from the first limiting member 212. In the closed state, the first limiting member 212 and the second limiting member 111 abut against each other to limit the relative position of the first movable cover 21 and the fixed cover 1.
[0100] Specifically, in the closed state, the first limiting member 212 abuts against the second limiting member 111, restricting the position of the first movable cover 21. At this time, due to the limiting force of the second limiting member 111 on the first limiting member 212, the first movable cover 21 will not rotate under its own weight. The first linkage member 211 abuts against the second linkage member 221, restricting the position of the second movable cover 22, thereby making the oven lid stably closed.
[0101] Specifically, see Figure 15 and Figure 16 In one embodiment, the fixed cover 1 includes a fixed cover portion 11 and a fixed side portion 12.
[0102] The fixed cover portion 11 is arc-shaped and is configured to extend along the length direction of the oven body 10 and be fixedly installed on the oven body 10.
[0103] The fixed side 12 is fan-shaped, and a fixed side 12 is provided at both ends of the fixed cover part 11. The arc end of the fixed side 12 is fixedly connected to the end of the fixed cover part 11, and the straight end of the fixed side 12 is configured to be fixedly installed on the oven body 10.
[0104] Adaptively, the shapes of the first movable cover 21 and the second movable cover 22 are also similar to those of the fixed cover 1. The fixed cover portion 11 is arc-shaped, so that when the first movable cover 21 and the second movable cover 22 rotate, the fixed cover portion 11 will not interfere with the rotation of the first movable cover 21 and the second movable cover 22, so that the two can be stacked with the fixed cover 1.
[0105] Furthermore, in one embodiment, the movable cover assembly 2 is movably connected to the top corner of the fixed side 12. This arrangement prevents the oven's center of gravity from shifting backward when the movable cover assembly 2 is opened, thus avoiding any impact on the oven's safety.
[0106] The fixed cover 1 of the above shape can always cover a part of the combustion chamber of the oven body 10. The straight end of the fixed side 12 is fixedly installed on the oven body 10, and the movable cover assembly 2 is hinged to the top corner of the fixed side 12. With this configuration, compared with the prior art, the rotation fulcrum of the movable cover assembly 2 is further away from the end of the oven body 10 in the width direction. This configuration makes the position of the oven cover in the open state more stable.
[0107] Specifically, the lower end of the fixed side 12 is fixedly mounted to the oven body 10 by screws.
[0108] It is understood that in this embodiment, the movable cover assembly 2 includes two movable covers, namely a first movable cover 21 and a second movable cover 22 that are movable.
[0109] Of course, in other embodiments, the movable cover assembly 2 may also include only a first movable cover 21, which can open or close the grilling cavity of the oven body 10 by rotating relative to the fixed cover 1.
[0110] Alternatively, in other embodiments, the movable cover assembly 2 may include three or more movable covers, which can be set as needed and will not be limited here.
[0111] In this embodiment, the movable cover assembly 2 includes a first movable cover 21 and a second movable cover 22, which has the following advantages: on the one hand, compared with only one movable cover, when the upper cover assembly is in the open state, its opening angle β can be a relatively large obtuse angle, which makes it convenient for users to operate the food; on the other hand, compared with three or more movable covers, the movable cover assembly 2 in this embodiment has a simple and stable structure and is easy to operate.
[0112] Furthermore, in some embodiments, see Figure 15 and Figure 16To further ensure the oven lid remains stable when open and prevent the first movable cover 21 and the second movable cover 22 from sliding in the unfolding direction under their own weight or due to external forces, the fixed cover 1 is also equipped with a latch 112. The latch 112 can engage or disengage with the first movable cover 21 and the second movable cover 22. Correspondingly, the first movable cover 21 is provided with a first engaging through hole for engaging with the latch 112, and the second movable cover 22 is provided with a second engaging through hole for engaging with the latch 112.
[0113] Specifically, when the oven lid is in the open state, the latch 112 passes through the first and second latching holes in sequence, which limits the first movable cover 21 and the second movable cover 22 on the one hand, and further reduces the impact of external wind on the oven lid on the other hand. When the oven lid is switched from the open state to the closed state, the latch 112 can also separate from the second and first latching holes in sequence.
[0114] Specifically, in this embodiment, the first snap-fit hole is provided on the first abutting limiting plate 213; the second snap-fit hole is provided on the second abutting limiting plate 222.
[0115] See Figure 1 A stress analysis was performed on the oven lid 200 of the existing oven when it was exposed to wind:
[0116] Because the oven lid 200 is a one-piece design, its vertical dimension is relatively large when it is open. Its pivot point on the oven body 100 is located at one end of the width direction of the oven body 100. This results in a large vertical dimension between the highest point of the open oven lid 200 and its pivot point, leading to a larger windward area and a longer lever arm for the wind force acting on the highest point. Consequently, the force required to knock over the oven lid 200 is relatively small. This means that even a small breeze can knock over the open oven lid 200, potentially causing it to suddenly cover the oven body 100, posing a safety hazard.
[0117] The following is a stress analysis of the oven lid provided in this embodiment when it is blown by wind:
[0118] See Figure 3In this embodiment, when the oven lid is in the open state, the fixed cover 1, the first movable cover 21, and the second movable cover 22 are stacked sequentially. This results in a relatively small vertical dimension between the highest point of the open oven lid and its rotation fulcrum, a smaller windward area for the oven lid, and a relatively short lever arm for the wind force acting on the highest point of the oven lid. Consequently, the force required to knock over the oven lid is relatively large. Simultaneously, since the straight end of the fixed side 12 is fixedly mounted to the oven body 10, the connector used in the fixed cover 1—one of the components of the oven lid—can offset some of the wind force, further reducing the impact of wind on the oven lid. In other words, even strong winds will not knock over the open oven lid.
[0119] In this embodiment, when the oven lid is in the open state, the fixed cover 1, the first movable cover 21 and the second movable cover 22 are stacked in sequence, which makes the opening angle of the oven lid larger. The open oven lid will not block the light, making it more convenient for users to operate the food in the oven body 10.
[0120] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0121] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
