Description

Technical Field

[0001] This utility model belongs to the field of oven installation technology, specifically relating to an assembly structure for a heating element. Background Technology

[0002] An oven mainly consists of a cabinet, heating elements, a thermostat, a timer, and a power adjustment switch. The heating methods of an oven can be divided into three types: top heating, bottom heating, and simultaneous top and bottom heating. In order to achieve consistency in the internal structure of the cavity, current oven products hide the lower heating element under the bottom plate of the cavity to achieve concealed heating. The lower heating element is fixed in a heating element cover to prevent the heat from the heating element from radiating to the bottom plate and reduce the impact of radiant heat on the temperature of the bottom plate. Therefore, it is necessary to design an assembly structure for the heating element.

[0003] Currently, most oven heating elements are fixed by welding. The heating element is welded to a fixing plate or limiting plate, and then fixed to the heating element cover by the fixing plate and limiting plate. This structure increases the complexity of the heating element manufacturing process, and welding operations are required during the later manufacturing process, increasing the manufacturing cost. In addition, the fixing plate or limiting plate that matches the heating element cover needs to be welded during the installation process, which reduces the convenience and flexibility of the later installation. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed assembly structure for heating tubes in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An assembly structure for a heating element includes a heat insulation plate. Multiple connecting components are installed on the top of the heat insulation plate. M-shaped heating elements or straight heating elements are placed inside the multiple connecting components. Multiple protective covers are fixedly installed at the middle position of the top of the heat insulation plate, covering the top of the connecting components, and the protective covers are positioned below the M-shaped heating elements or straight heating elements.

[0007] As a further optimization of this utility model, the connecting component includes multiple guide grooves opened on both sides of the top of the heat insulation plate and connected to the inside of the protective cover. The interior of the two guide grooves at the same end is slidably connected to an L-shaped limiting block extending to the outside. The interior of the multiple L-shaped limiting blocks is engaged with an M-shaped heating tube or a straight heating tube. The bottom of one side of the multiple L-shaped limiting blocks is connected to a connecting rope.

[0008] As a further optimization of this utility model, springs are fixedly installed on the sides of the two guide grooves at the same end that are close to each other, and the sides of the two springs that are far apart are fixedly connected to the bottom of the sides of the two L-shaped limiting blocks that are close to each other.

[0009] As a further optimization of this utility model, each of the two L-shaped limiting blocks has an opening on its top side away from each other, and the multiple openings engage with the two ends of the straight heating tube.

[0010] As a further optimization of this utility model, the top of each of the L-shaped limiting blocks on the side closest to each other is provided with an arc-shaped opening groove that cooperates with the M-shaped heating tube or the straight heating tube. The side of the arc-shaped opening groove that is far apart from each other is connected to the inside and outside of the through-hole.

[0011] As a further optimization of this utility model, a connecting rope ring is fixedly installed on the bottom of one side of each of the L-shaped limiting blocks, and a connecting rope is fixedly connected to the inner side of each of the connecting rope rings.

[0012] The beneficial effects of this utility model are as follows: Through the structural design of the connecting components, this utility model facilitates the operator's subsequent installation of M-shaped or I-shaped heating elements, eliminating the need for welding external fixing plates or limiting plates during the manufacturing process. This reduces the manufacturing cost of the heating elements and simplifies the production process. Furthermore, this structural design allows for the installation of two different types of heating elements, increasing the installation range. During installation, only the L-shaped limiting block needs to be pulled, ensuring convenient and flexible installation and facilitating easy disassembly and replacement of the heating elements by the operator.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an assembly structure for a heating element includes a heat insulation plate 1. The heat insulation plate 1's structural design achieves heat insulation, preventing damage to the bottom of the oven caused by high temperatures. Multiple protective covers 5 are fixedly installed at the center of the top of the heat insulation plate 1. The installation design of the protective covers 5 facilitates the subsequent covering and protection of components. Multiple connecting components 2 are installed at the bottom of the protective covers 5 on the top of the heat insulation plate 1. The structural design of the connecting components 2 facilitates the limiting installation of the heating element. The connecting components 2 include multiple guide grooves 200 formed on both sides of the top of the heat insulation plate 1 and communicating with the interior of the protective covers 5. Multiple pairs of guide grooves 200 can be formed according to actual operational needs. In this invention, only three pairs of guide grooves 200 are formed on the top of the heat insulation plate 1. These three pairs of guide grooves 200 are placed on both sides of the bottom of the protective covers 5 and communicate with their interior. Both guide grooves 200 at the same end have L-shaped limiting blocks 201 extending to their exterior slidably connected inside. Springs 204 are fixedly installed on the adjacent sides of both guide grooves 200 at the same end. The opposite sides of the two springs 204 are fixedly connected to the bottom of the adjacent sides of the two L-shaped limiting blocks 201, facilitating the connection and reset function of the L-shaped limiting blocks 201. The elasticity of the springs 204 achieves the subsequent installation limiting operation of the heating element. The top of the adjacent sides of the multiple L-shaped limiting blocks 201 are each provided with an arc-shaped opening groove that mates with the M-shaped heating element 3 or the straight heating element 4. The arc-shaped opening groove design facilitates the locking and limiting of the M-shaped heating element 3 or the straight heating element 4. The top of the opposite sides of the two L-shaped limiting blocks 201 are each provided with a through-hole 203. Multiple through-holes 203 communicate with the inside and outside of the arc-shaped opening grooves. The through-holes 203, like... Figure 4The diagram shows the locking and limiting operation of the two ends of the straight heating tube 4, which enables the fixed connection of two different types of heating tubes. The bottom of one side of multiple L-shaped limiting blocks 201 is fixedly installed with connecting rope rings placed above the heat insulation plate 1. The inner side of each connecting rope ring is fixedly connected with a connecting rope 202, which facilitates the connection and locking operation of the connecting rope 202. The connecting rope 202 is a connecting rope woven from alumina ceramic fiber by special means, which allows the operator to simultaneously pull and displace the three L-shaped limiting blocks 201 on one side through the connecting rope 202.

[0022] It should be noted that, in the assembly structure of this heating element, the operator can directly fix the heat insulation plate 1 and above to the inner bottom of the oven. Later, by pulling the connecting rope 202, the three L-shaped limiting blocks 201 can be pulled simultaneously, allowing them to slide inside the guide groove 200. This stretches the spring 204, and the movement of the three L-shaped limiting blocks 201 facilitates the operator's later removal of the M-shaped heating element 3, placing it inside the three pairs of L-shaped limiting blocks 201. Finally, releasing the connecting rope 202 allows the spring 204 to reset the L-shaped limiting blocks 201, thus completing the fixed installation of the M-shaped heating element 3. Figure 1 , Figure 5 As shown, the installation method designed by this mechanism allows operators to simply pull the connecting rope 202, which effectively improves the convenience and flexibility of disassembling and assembling the heating element. At the same time, there is no need to weld fixing plates or limiting plates to the outside of the heating element, ensuring the convenience of the heating element manufacturing process.

[0023] When it is necessary to fix the straight heating element 4, the operator only needs to pull the L-shaped limiting block 201 on the other side that is not connected to the connecting rope 202. By pulling the individual L-shaped limiting block 201, the straight heating element 4 can be easily moved through the port 203. Figure 4 The limiting engagement shown can be achieved to ensure the range for subsequent fixed installation of the heating element.

[0024] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but 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 several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
