Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a heating tube installation structure and cooking equipment. Background Technology

[0002] As people's quality of life continues to improve, steam ovens, ovens, and multi-functional appliances are becoming increasingly popular. While these cooking devices offer diverse cooking functions, they also present the challenge of cleaning the inner pot.

[0003] Currently, some cooking appliances employ a reversible heating element design, allowing the heating element to be tilted downwards at a certain angle when cleaning the top of the cooking cavity. This design facilitates thorough cleaning of the top of the cooking cavity using cleaning tools and detergents. However, for appliances with integrated steam cooking functions, a large amount of water vapor is generated during cooking, making it crucial to maintain the sealing of the cooking cavity. During cleaning, tilting the heating element may affect the sealing of the cooking cavity, leading to steam leakage. Water vapor leakage not only affects cooking efficiency but can also easily cause other components to become damp and damaged.

[0004] Therefore, it is urgent to solve the technical problem that the tumbling motion of the heating element can easily affect the sealing of the cooking cavity. Utility Model Content

[0005] This utility model provides a heating tube installation structure and cooking equipment to solve the technical problem that the tumbling movement of the heating tube can easily affect the sealing of the cooking cavity.

[0006] To achieve the above objectives, this utility model provides a heating tube mounting structure, comprising:

[0007] A fixing plate, which forms the inner wall of the cooking cavity;

[0008] A bracket, which is connected to the fixing plate on the side facing the cooking cavity;

[0009] A heating element assembly, rotatably connected to the bracket, the heating element assembly including a connecting section passing through the fixed plate;

[0010] A sealing element is disposed between the bracket and the fixed plate, and the sealing element is wrapped around the outer wall of the connecting section to maintain a seal between the heating tube assembly and the fixed plate when the heating tube assembly rotates relative to the bracket.

[0011] This application provides a heating tube mounting structure. The heating tube assembly is rotatably connected to a bracket, and a seal is disposed between the bracket and a fixed plate. The seal wraps around the outer wall of the connecting section. When the heating tube assembly rotates relative to the bracket, the seal can tightly fit the inner bracket and the fixed plate and wrap around the outer wall of the connecting section. This ensures that the rotation of the heating tube assembly does not affect the sealing between the outer wall of the connecting section and the seal, effectively preventing steam leakage in the cooking cavity, ensuring cooking efficiency, and preventing leaked steam from affecting the normal operation of other components.

[0012] In one possible implementation, the seal is a flexible element, and the seal has a plurality of spaced-apart mounting holes.

[0013] The heating tube assembly includes a heating tube, the connecting section is located at the end of the heating tube, the connecting section extends into the mounting hole, and the outer peripheral surface of the connecting section elastically abuts against the inner wall surface of the mounting hole.

[0014] In one possible implementation, the seal has a groove on the side facing the bracket, and a plurality of mounting holes penetrate the bottom surface of the groove.

[0015] In one possible implementation, the fixing plate has a fixing hole, and the sealing element includes:

[0016] A sealing body portion extends into the fixing hole, and both the mounting hole and the groove are located within the sealing body portion;

[0017] A flange portion is connected to the edge of the sealing body portion facing one end of the bracket, and the flange portion abuts between the bracket and the fixing plate.

[0018] In one possible implementation, the bracket includes a connecting plate with a clearance hole, the connecting segment passing through the clearance hole and the mounting hole in sequence, and extending to the side of the fixing plate opposite to the cooking cavity.

[0019] In one possible implementation, the bracket further includes a limiting plate connected to both ends of the connecting plate, the limiting plate having limiting holes.

[0020] The heating tube assembly also includes a flange plate, which is fixed to the connecting section. Both ends of the flange plate are movably disposed within the limiting holes to control the rotation angle of the heating tube assembly.

[0021] In one possible implementation, the inner wall of the limiting hole has a first limiting surface and a second limiting surface, and the flange plate moves between a first position abutting against the first limiting surface and a second position abutting against the second limiting surface.

[0022] In one possible implementation, the included angle between the first limiting surface and the second limiting surface is <90°.

[0023] In one possible implementation, the heating element mounting structure further includes a locking assembly, wherein one end of the heating element assembly remote from the connecting section is detachably connected to the inner wall of the cooking cavity via the locking assembly.

[0024] This application also provides a cooking device, including the heating tube mounting structure described above.

[0025] This application provides a heating tube installation structure and cooking equipment. The heating tube assembly rotates through the limiting hole of the bracket via a flange plate. The rotation angle is controllable. Furthermore, a sealing element is elastically wrapped around the outer wall of the connecting section, ensuring that the sealing between the fixing plate and the connecting section is not affected during the rotation of the heating tube assembly, thus guaranteeing the airtightness of the connection and improving thermal efficiency and operational reliability.

[0026] The heating element installation structure and cooking device provided in this application can make full use of the weight of the heating element assembly itself during the flipping process, without the need for additional tools or instruments to disassemble it, and without the need for the user to manually flip the heating element assembly again, thus simplifying the operation process.

[0067] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0068] After prolonged use, cooking appliances accumulate a large amount of grease and grime on the inner walls of the cooking cavity. Because the heating elements are installed very close to the ceiling area of ​​the cooking cavity (the inner top wall), the space between the heating elements and the ceiling is extremely narrow, only a few centimeters, and there are multiple heating elements, forming a complex heating circuit structure. This design presents a considerable challenge for users when cleaning the ceiling area of ​​the cooking cavity, especially when using cleaning tools and detergents. Cleaning tools such as sponges are almost impossible to effectively reach the ceiling area, making it difficult to thoroughly clean the grime.

[0069] To facilitate cleaning of the cooking cavity, the heating element can be rotated downwards at a certain angle when cleaning the ceiling area of ​​the cooking cavity, providing ample space for cleaning tools and improving cleaning convenience. However, some cooking appliances integrate steam cooking functions. If rotating the heating element downwards at a certain angle causes steam leakage, it will affect cooking efficiency and the normal operation of other electronic components in the cooking appliance. Therefore, while considering the convenience of cleaning by rotating the heating element downwards, it is also necessary to ensure the sealing of the cooking cavity.

[0070] In view of this, the heating tube installation structure and cooking equipment provided by this utility model, by setting the sealing element between the bracket and the fixing plate and wrapping the sealing element around the outer wall of the connecting section, when the heating tube assembly rotates relative to the bracket, the sealing element can tightly fit the inner bracket and the fixing plate and wrap around the outer wall of the connecting section, so that the rotation of the heating tube assembly will not affect the sealing between the outer wall of the connecting section and the sealing element, effectively preventing steam leakage in the cooking cavity, ensuring cooking efficiency, and also preventing leaked steam from affecting the normal operation of other components.

[0071] refer to Figure 1 and Figure 2 As shown, this application embodiment provides a heating element mounting structure, including: a fixing plate 10, a bracket 20, a heating element assembly 30, and a sealing element 40. The fixing plate 10 forms the inner wall of the cooking cavity. The bracket 20 is connected to the side of the fixing plate 10 facing the cooking cavity; the heating element assembly 30 is rotatably connected to the bracket 20, and the heating element assembly 30 includes a connecting section 311 passing through the fixing plate 10. (Reference) Figure 1 , Figure 3 and Figure 4 As shown, the sealing element 40 is disposed between the bracket 20 and the fixing plate 10, and the sealing element 40 is wrapped around the outer wall of the connecting section 311 so that the heating tube assembly 30 and the fixing plate 10 remain sealed when the heating tube assembly 30 rotates relative to the bracket 20.

[0072] This application provides a heating tube mounting structure. The heating tube assembly 30 is rotatably connected to the bracket 20. The sealing member 40 is disposed between the bracket 20 and the fixing plate 10, and the sealing member 40 is wrapped around the outer wall of the connecting section 311. When the heating tube assembly 30 rotates relative to the bracket 20, the sealing member 40 can tightly fit the inner bracket 20 and the fixing plate 10, and wrap around the outer wall of the connecting section 311, so that the rotation of the heating tube assembly 30 will not affect the sealing between the outer wall of the connecting section 311 and the sealing member 40, effectively preventing steam leakage in the cooking cavity, ensuring cooking efficiency, and also preventing leaked steam from affecting the normal operation of other components.

[0073] In one possible implementation method, refer to Figure 3 and Figure 5 As shown, the fixing plate 10 can be the side wall of the cooking cavity or the rear cover plate of the cooking cavity. The fixing plate 10 provides basic structural support.

[0074] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 4 As shown, the bracket 20 can be connected to the side of the fixing plate 10 facing the cooking cavity by fastener 60. The bracket 20 and the fixing plate 10 together compress the sealing member 40. When compressed, the sealing member 40 undergoes elastic deformation, tightly filling the gap between the bracket 20 and the fixing plate 10, ensuring that there are no gaps between the bracket 20 and the fixing plate 10 for steam to pass through and leak, thus achieving a sealing effect between the bracket 20 and the fixing plate 10.

[0075] In one possible implementation, since the support 20 will be subjected to high temperatures within the cooking cavity, the support 20 is made of a high-temperature resistant material, such as stainless steel or a high-temperature alloy.

[0076] In one possible implementation method, refer to Figure 2 , Figure 7 and Figure 8 As shown, the sealing element 40 is a flexible element, and a plurality of mounting holes 411 are arranged at intervals inside the sealing element 40. The heating tube assembly 30 includes a heating tube 31, and a connecting section 311 is located at the end of the heating tube 31. The connecting section 311 extends into the mounting hole 411, and the outer peripheral surface of the connecting section 311 elastically abuts against the inner wall surface of the mounting hole 411.

[0077] The sealing element 40 is a flexible component, giving the inner wall of the mounting hole 411 elasticity. The mounting hole 411 can tightly abut against the outer circumferential surface of the connecting section 311, providing not only good sealing performance but also allowing for a certain degree of thermal expansion and contraction. This accommodates the thermal expansion of the heating tube 31 at high temperatures, reducing the risk of seal failure due to stress caused by thermal expansion and contraction, and achieving a stable sealing effect between the mounting hole 411 and the connecting section 311. Furthermore, the elasticity of the inner wall of the mounting hole 411 makes the installation and removal of the heating tube 31 more convenient, facilitating maintenance and replacement.

[0078] In one possible implementation, the number of mounting holes 411 is the same as the number of connecting segments 311.

[0079] In this embodiment, the heating tube 31 is responsible for providing heat to generate steam in the cooking cavity. The connecting section 311 is connected to both ends of the heating tube 31, serving as a connection and fixation mechanism. This design ensures that the heating tube 31 can be stably installed in the required position and effectively conducts heat to achieve the heating and steam generation functions in the cooking cavity. The middle section of the heating tube 31 can be coiled in a plane.

[0080] In one possible implementation, the seal 40 can be a rubber or silicone component. The seal 40 is made of a high-temperature and steam-resistant sealing material to ensure long-term use in high-temperature and high-humidity environments.

[0081] In one possible implementation method, refer to Figure 2 , Figure 7 and Figure 8 As shown, the sealing member 40 has a groove 412 on the side facing the bracket 20, and multiple mounting holes 411 penetrate the bottom surface of the groove 412.

[0082] The mounting hole 411 is a through hole. By setting the groove 412, the length of the mounting hole 411 is reduced, and the inner wall of the mounting hole 411 is more flexible and flexible, making it easier to fit the connecting section 311 of the heating tube 31, effectively preventing the leakage of steam and heat, and improving the sealing performance between the mounting hole 411 and the connecting section 311.

[0083] In addition, the groove 412 can provide additional elastic deformation and buffer space for the seal 40, which helps the seal 40 absorb stress during the installation process, and absorb and relieve stress when the heating tube assembly 30 rotates relative to the bracket 20, reducing the seal failure caused by thermal expansion or mechanical vibration of the heating tube assembly 30, and improving the overall sealing effect and sealing stability.

[0084] In one possible implementation, the groove 412 can be a rectangular groove, an elliptical groove, etc., and the end of the mounting hole 411 facing the bracket 20 is connected to the groove 412.

[0085] In one possible implementation method, refer to Figure 1 , Figure 7 and Figure 8 As shown, a fixing hole 11 is provided in the fixing plate 10. The sealing element 40 includes a sealing body part 41 and a flange part 42. The sealing body part 41 extends into the fixing hole 11. The mounting hole 411 and the groove 412 are both located in the sealing body part 41. The flange part 42 is connected to the edge of the sealing body part 41 facing the end of the bracket 20. The flange part 42 abuts between the bracket 20 and the fixing plate 10.

[0086] In one possible implementation, the sealing body 41 and the flange 42 can be an integrally connected structure.

[0087] In one possible implementation, the end of the sealing body 41 facing away from the support 20 is rounded. This reduces the presence of sharp edges and lowers the likelihood of wear and tear.

[0088] The sealing body 41 extends into the fixing hole 11, and the sealing body 41 is interference-fitted with the fixing hole 11 to ensure that the sealing body 41 is tightly fitted to the inner wall surface of the fixing hole 11, providing stable installation and good sealing effect.

[0089] Integrating the mounting hole 411 and the groove 412 into the sealing body 41 simplifies the structural design and improves the overall strength and functionality of the seal 40.

[0090] refer to Figure 1 , Figure 4 and Figure 9 As shown, the flange 42 forms an additional sealing layer to prevent steam and heat from leaking between the bracket 20 and the fixing plate 10. The flange 42 abuts against the bracket 20 and the fixing plate 10, and can also prevent the seal 40 from moving during use, thus improving the stability of the seal 40 installation.

[0091] In one possible implementation method, refer to Figure 1 , Figure 9 and Figure 10 As shown, the bracket 20 includes a connecting plate 21, in which a clearance hole 211 is provided. The connecting section 311 passes through the clearance hole 211 and the mounting hole 411 in sequence, and extends to the side of the fixing plate 10 facing away from the cooking cavity. This structure allows the bracket 20 to provide a certain degree of support for the heating tube assembly 30, maintaining the installation stability of the heating tube assembly 30.

[0092] In one possible implementation, the clearance hole 211 can be a circular hole, a rectangular hole, etc., so that the connecting section 311 can pass through without obstruction. By opening the clearance hole 211 in the connecting plate 21, the sealing effect between the heating tube assembly 30 and the seal 40 will not be affected.

[0093] In one possible implementation, holes for fasteners 60 are provided in the connecting plate 21, the flange portion 42, and the fixing plate 10. The fasteners 60 include, but are not limited to, screws, bolts, etc., and nuts are threaded onto the fasteners 60 to improve the tightness of the connection between the bracket 20, the seal 40, and the fixing plate 10.

[0094] refer to Figure 1 , Figure 6 and Figure 7 As shown, when the heating tube assembly 30 rotates, the fixing method of the bracket 20, the seal 40, and the fixing plate 10 is not damaged. The seal between the bracket 20 and the fixing plate 10 will not be damaged. At the same time, due to the elasticity of the seal 40, the inner wall of the mounting hole 411 elastically abuts against the outer peripheral surface of the connecting section 311. When the heating tube assembly 30 rotates, the seal between the connecting section 311 and the inner wall of the mounting hole 411 will not be damaged. This ensures good sealing inside the cooking cavity, prevents steam leakage inside the cooking cavity from affecting the electronic components inside the cooking equipment, and ensures the working efficiency of the cooking equipment and the normal operation of the electronic components outside the cooking cavity.

[0095] In one possible implementation method, refer to Figure 10 , Figure 11 and Figure 12 As shown, the bracket 20 also includes a limiting plate 22, which is connected to both ends of the connecting plate 21, and a limiting hole 221 is provided in the limiting plate 22; the heating tube assembly 30 also includes a flange plate 32, which is fixed to the connecting section 311, and both ends of the flange plate 32 are movably disposed in the limiting hole 221 to control the rotation angle of the heating tube assembly 30.

[0096] In one possible implementation, the limiting plate 22 and the connecting plate 21 can be an integral structure that is connected as a whole.

[0097] In one possible implementation, the flange plate 32 has multiple through holes 322, the connecting section 311 passes through the through holes 322, and a sealing ring is embedded between the outer peripheral surface of the connecting section 311 and the inner wall surface of the through hole 322, so as to fix the flange plate 32 to the connecting section 311.

[0098] refer to Figure 1 , Figure 11 and Figure 12As shown, the flange plate 32 is fixed to the connecting section 311, so that multiple heating tubes 31 are connected into an integral structure. When the flange plate 32 rotates within the limiting hole 221, it facilitates the rotation of multiple heating tubes 31 as a whole, thereby adjusting the rotation angle of the heating tube assembly 30.

[0099] In one possible implementation, both ends of the flange plate 32 have extension plates 321, which are movably disposed within the limiting holes 221. The extension plates 321 are narrower than the flange plate 32.

[0100] The function of the limiting hole 221 is to limit the range of motion of the flange plate 32, thereby controlling the rotation angle of the heating tube assembly 30. (Reference) Figure 5 , Figure 6 and Figure 12 As shown, when cleaning is required, the heating element assembly 30 should be flipped downwards at a certain angle, with the flipping direction as referenced. Figure 12 The arrow Q indicates the direction to increase the distance between the heating element assembly 30 and the top of the cooking cavity, allowing cleaning tools and detergents to more easily reach the top of the cooking cavity for thorough cleaning. (Reference) Figure 3 and Figure 4 As shown, after cleaning, the heating tube assembly 30 is flipped upwards at a certain angle to ensure that the heating tube assembly 30 is returned to a suitable working position for cooking, so as to reduce the gap between the heating tube assembly 30 and the top of the cooking cavity. This helps to prevent food in the cooking cavity from hitting the heating tube assembly 30 and also prevents the heating tube assembly 30 from obstructing the food from being placed in the cooking cavity.

[0101] In one possible implementation method, refer to Figure 10 and Figure 11 As shown, the inner wall of the limiting hole 221 has a first limiting surface 2211 and a second limiting surface 2212, and the flange plate 32 moves between a first position abutting the first limiting surface 2211 and a second position abutting the second limiting surface 2212.

[0102] In this example, the first position is the working position of the heating tube assembly 30 suitable for cooking, and the second position is the position after the heating tube assembly 30 is flipped downwards at a certain angle. Through a simple flipping action, users can easily clean and maintain it, improving the user experience.

[0103] The first limiting surface 2211 and the second limiting surface 2212 provide physical limiting, ensuring that the heating tube assembly 30 does not exceed its range during the flipping process, thus avoiding possible damage or misoperation. The flange plate 32 moves between a first position abutting against the first limiting surface 2211 and a second position abutting against the second limiting surface 2212, allowing the heating tube assembly 30 to be flexibly adjusted between the first and second positions. The user can flip the heating tube assembly 30 to the appropriate position as needed.

[0104] In one possible implementation, one end of the first limiting surface 2211 and one end of the second limiting surface 2212 intersect to form a junction. The end of the extension plate 321 extending to the junction is arc-shaped, which allows the extension plate 321 to rotate more smoothly within the limiting hole 221. This helps to reduce rotational friction and resistance, thereby improving the smoothness and efficiency of the movement and enabling the heating tube assembly 30 to rotate in the specified direction.

[0105] In one possible implementation, the included angle between the first limiting surface 2211 and the second limiting surface 2212 is <90°. This limits the maximum rotation angle of the heating tube assembly 30 to less than 90°, making the movement of the heating tube assembly 30 between the first limiting surface 2211 and the second limiting surface 2212 more controlled, improving operational safety, preventing the user from accidentally rotating the heating tube assembly 30 to an unsafe position during operation, and avoiding affecting the sealing between the connecting section 311 and the seal 40 due to excessive rotation angle of the heating tube assembly 30.

[0106] In one possible implementation method, refer to Figure 1 , Figure 3 and Figure 5 As shown, the heating element mounting structure also includes a locking component 50, through which the end of the heating element assembly 30 furthest from the connecting section 311 is detachably connected to the inner wall of the cooking cavity. The locking component 50 provides a quick and reliable fixing method while ensuring the stability and safety of the connection of the heating element assembly 30.

[0107] In one possible implementation, the locking assembly 50 includes a mounting bracket 51 and a locking element 52. The mounting bracket 51 is connected to the end of the heating tube assembly 30 away from the connecting section 311. The mounting bracket 51 has a locking plate 511, and the locking element 52 is connected to the inner wall surface of the cooking cavity through the locking plate 511.

[0108] The locking element 52 can be a snap-fit ​​that engages with the inner wall of the cooking cavity, so that the end of the heating tube assembly 30 away from the connecting section 311 is connected to the inner wall of the cooking cavity. The locking element 52 can also be a screw, which fixes the end of the heating tube assembly 30 away from the connecting section 311 to the top wall of the cooking cavity.

[0109] When the heating tube assembly 30 is working normally, the heating tube assembly 30 is connected to the inner wall of the cooking cavity by the locking component 50, which can prevent the heating tube assembly 30 from rotating. The sealing component 40 is disposed between the bracket 20 and the fixing plate 10, and the sealing component 40 is wrapped around the outer wall of the connecting section 311 to ensure the airtightness of the cooking cavity.

[0110] This application also provides a cooking device, including the heating tube mounting structure described above.

[0111] This application provides a cooking device, including but not limited to steam ovens, ovens, and steam-grill combos.

[0112] When there is no need to clean the inner top wall of the cooking cavity, with the heating tube assembly 30 in the first position, the end of the heating tube assembly 30 furthest from the connecting section 311 is connected to the top wall of the cooking cavity by the locking component 50. The connecting section 311 of the heating tube assembly 30 is sealed between the sealing member 40 and the fixing hole 11 of the fixing plate 10. The bracket 20 and the fixing plate 10 press against each other to compress the sealing member 40, causing the sealing member 40 to undergo elastic deformation, thus ensuring the airtightness of the inside of the cooking cavity.

[0113] When the user needs to clean the inner top wall of the cooking cavity, simply disengage the locking piece 52 from the inner wall surface of the cooking cavity, as shown in the reference. Figure 1 and Figure 12 As shown, under the action of gravity F of the heating tube assembly 30, the flange plate 32 can rotate within the limiting hole 221 and flip down a certain angle from the first position to the second position. At this time, the user can more easily clean the inner top wall of the cooking cavity. After cleaning, the heating tube assembly 30 is connected to the inner wall of the cooking cavity by locking component 50.

[0114] This application provides a heating tube installation structure and cooking equipment. The heating tube assembly 30 rotates through the limiting hole 221 of the bracket 20 via the flange plate 32. The rotation angle is controllable. Furthermore, the sealing element 40 is elastically wrapped around the outer wall of the connecting section 311, so that the sealing between the fixing plate 10 and the connecting section 311 is not affected during the rotation of the heating tube assembly 30, ensuring the airtightness of the connection, thereby improving thermal efficiency and operational reliability.

[0115] The heating tube mounting structure and cooking device provided in this application can make full use of the weight of the heating tube assembly 30 itself during the flipping process, without the need for additional tools or instruments to disassemble it, and without the need for the user to manually flip the heating tube assembly 30 again, thus simplifying the operation process.
