Description

Technical Field

[0001] The present application relates to the field of electrical appliance technology, and in particular to a heating tube installation structure and an oven. Background Art

[0002] In the related art, there is an oven that uses graphite heating tubes for heating. The heating material of the graphite heating tubes is graphite sheets. Graphite sheets are a new type of thermal conductive and heat dissipation material that can be heated evenly in both directions. It has the advantages of fast response speed, strong radiation, and fast heating. Due to the price of graphite sheets and other reasons, the thickness of the graphite sheets used in graphite heating tubes is generally thin, and the thinnest is only 0.1mm. At the same time, in order to ensure the high efficiency of heat generation and heat transfer of the graphite sheets, the graphite sheets are usually encapsulated in quartz tubes. Since the thickness of the graphite sheets themselves is relatively thin and the brittleness of the quartz tubes is relatively large, it is easy for the graphite heating tubes to be damaged during transportation of the oven. At the same time, after the graphite heating tubes have been used for a long time, the graphite sheets are also prone to oxidation and fracture. For the above situations, the heating tubes need to be replaced.

[0003] However, in the prior art, the operation steps for replacing the graphite heating tube are relatively complicated, the operator needs to spend a lot of time, and there is no safety guarantee. Utility Model Content

DETAILED DESCRIPTION

[0037] In the description of the embodiments of the present application, it should be noted that the term "horizontal direction" is based on the attached Figure 4 These directional terms are only used to facilitate the description of the embodiments of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application.

[0038] The present application embodiment provides an oven, see Figures 1 to 6 The oven includes a shell 200 , a heating pipe 400 and a heating pipe mounting structure 100 , and the heating pipe mounting structure 100 is arranged in the shell 200 .

[0039] Terminals 410 are provided at both ends of the heating tube 400. When the two terminals 410 at both ends are connected to the positive and negative poles of a power source respectively, the heating tube 400 generates heat.

[0040] See also Figures 3 to 6 The heating pipe installation structure 100 of the embodiment of the present application includes a first wall plate 10 , a second wall plate 20 , a clamp seat 30 and a connecting wire 40 .

[0041] The first wall panel 10 and the second wall panel 20 are opposite to each other and spaced apart. The second wall panel 20 is provided with at least two plug holes 20a. The clamp seat 30 is provided on the first wall panel 10 and corresponds to the plug holes 20a one by one. The clamp seat 30 includes an elastic clip 31. The connecting wire 40 is provided on the second wall panel 20 and has a terminal head 42.

[0042] The heating tube mounting structure 100 is used to mount the heating tube 400. Specifically, a heating space is formed between the first wall plate 10 and the second wall plate 20. The heating tube 400 extends from the corresponding plug hole 20a into between the first wall plate 10 and the second wall plate 20. One end of the heating tube 400 is clamped in the elastic clip 31. That is, one end of the heating tube 400 is detachably connected to the clamp seat 30 through the clamping action of the elastic clip 31, and the other end of the heating tube 400 is detachably connected to the corresponding terminal head 42.

[0043] The number of the heating tube 400 may be one or more, and the number of the plug holes 20a is consistent with the number of the heating tubes 400. Figure 3 The heating pipe installation structure 100 shown is used to install two heating pipes 400 , and therefore, the heating pipe installation structure 100 is provided with two plug holes 20 a .

[0044] See also Figure 2 and Figure 3 The heating tube 400 is electrically connected to the power supply circuit via the connecting wire 40. The connecting head 42 on the connecting wire 40 is detachably connected to the terminal 410 on the heating tube 400 to achieve electrical connection with the heating tube 400.

[0045] Figure 3 The connecting wire 40 on the second wall panel 20 is used to connect two heating tubes 400 in series. In other embodiments, depending on the number of heating tubes 400, the connecting wire 40 can also be connected in parallel or in combination of series and parallel, as long as each heating tube 400 can be electrically connected to the power supply circuit.

[0046] When a heating tube 400 needs to be repaired or replaced, it is only necessary to remove the terminal head 42 on the heating tube 400 and then pull the heating tube 400 out of the corresponding plug hole 20a. Similarly, the heating tube 400 after repair or replacement only needs to be inserted between the first wall plate 10 and the second wall plate 20 from the plug hole 20a, the end of the heating tube 400 close to the first wall plate 10 is clamped in the corresponding elastic clip 31, and the terminal head 42 on the corresponding connecting wire 40 is connected to the end of the heating tube 400 close to the second wall plate 20. The heating tube installation structure 100 effectively simplifies the operation steps when replacing the heating tube 400 and improves the convenience of disassembly and assembly of the heating tube 400.

[0047] In one embodiment, please refer to Figures 4 to 6The clamp seat 30 also includes a bracket 32, which is fixedly connected to the first wall plate 10. The elastic clip 31 includes a connecting portion 311 and two elastic clamping arms 312. The two elastic clamping arms 312 are respectively arranged on opposite sides of the connecting portion 311. One end of each elastic clamping arm 312 is connected to the connecting portion 311, and the other end opposite to each elastic clamping arm 312 is a free end 3121. The two free ends 3121 of the two elastic clamping arms 312 respectively abut against the two sides of the terminal 410 to clamp the terminal 410. Under the elastic force of the elastic clamping arms 312, the two free ends 3121 respectively apply clamping forces in opposite directions to the terminal 410. The heating tube 400 is stably detachably installed on the elastic clip 31 through the friction force generated by the clamping force to maintain the installation stability during transportation or normal use.

[0048] When disassembling the heating tube 400, it is necessary to use a pulling force greater than the friction force to pull the terminal 410 out from between the two elastic clamping arms 312. In order to avoid the lack of stability in the installation of the heating tube 400 due to too small friction force, or the difficulty in pulling out the heating tube 400 due to too large friction force, preferably, the clamping force of the free end 3121 on the terminal 410 can be controlled within 20N-40N, but is not limited to this range. In actual production design, adaptive adjustment needs to be made according to the friction coefficient between the free end 3121 and the terminal 410.

[0049] For example, see Figure 6 When installing the heating tube 400, the terminal 410 near one end of the elastic clamp 31 needs to be inserted between the two free ends 3121. In order to facilitate the insertion of the terminal 410, the free ends 3121 of the two elastic clamping arms 312 are bent in directions away from each other to form an opening 31a between the two free ends 3121, and the opening 31a guides the insertion of the terminal 410.

[0050] The bending outer radius R of the free end 3121 of each elastic clamping arm 312 is preferably, but not limited to, 0.5 mm to 5 mm.

[0051] Please continue reading Figure 6, there is a gap 31b between the two elastic clamping arms 312, which is connected to the opening 31a. The gap 31b is located on the side of the opening 31a close to the connecting portion 311. When installing the heating tube 400, the terminal 410 extends into the gap 31b under the guidance of the opening 31a, and is clamped by the two free ends 3121 in the gap 31b. At this time, the elastic clamping arm 312 will increase the width of the gap 31b according to the thickness of the terminal 410 through a certain degree of elastic deformation to maintain the clamping force of the free end 3121 on the terminal 410. Therefore, the initial width of the gap 31b needs to be smaller than the thickness of the terminal 410 when designing to ensure the occurrence of elastic deformation. Optionally, the width of the gap 31b is 0.1mm-2mm.

[0052] It is understandable that in order to ensure that the elastic force generated by the elastic clamping arm 312 meets the working requirements, the elastic clamp 31 needs to select a suitable thickness to ensure that the elastic clamping arm 312 has a suitable elastic coefficient. The thickness of the elastic clamp 31 is preferably but not limited to 0.2mm-4mm, and can be adjusted according to the specific material of the elastic clamp 31.

[0053] Exemplarily, the elastic clip 31 may be made of metal, such as copper, iron, alloy, etc.

[0054] In one embodiment, please refer to Figure 6 Each elastic clamping arm 312 is bent to form a connecting section 3122, a transition section 3123 and a clamping section 3121 with a free end 3121. The transition section 3123 is located between the connecting section 3122 and the clamping section 3121. The transition section 3123 is tilted relative to the connecting section 3122 so that the clamping sections 3121 of the two elastic clamping arms 312 are close to each other.

[0055] The angle Q between the transition section 3123 and the connecting section 3122 is preferably 30 degrees to 60 degrees. The structural optimization is used to reduce the elastic fatigue of the elastic clamping arm 312 during long-term deformation, thereby increasing the service life and reducing the failure rate.

[0056] In one embodiment, please refer to Figure 4 and Figure 6 The elastic clip 31 is a conductive component having a conductive plug connector 313. The elastic clip 31 is electrically connected to the heating tube 400 through the clamping terminal 410. The conductive plug connector 313 is electrically connected to the power supply circuit through the power line 500, so that the terminal 410 can be electrically connected to the power supply circuit.

[0057] The location of the conductive plug connector 313 is not limited. For example, see Figure 6 The conductive plug connector 313 is disposed at the free end 3121 of one of the elastic clamping arms 312 .

[0058] In other embodiments, the conductive plug connector 313 may also be disposed on the connecting portion 311 .

[0059] See also Figure 5 and Figure 6 The clamp seat 30 may be provided with an insulating pad 34 , and the insulating pad 34 is clamped between the connecting portion 311 and the bracket 32 ​​to isolate the electrical conduction between the connecting portion 311 and the bracket 32 ​​.

[0060] See also Figures 3 to 6 The connecting portion 311 may also be connected to the bracket 32 ​​via an insulating fastener 33 .

[0061] Please continue reading Figures 3 to 6 There may be two insulating fasteners 33, and the connecting portion 311 is provided with two positioning holes 311a corresponding to the insulating fasteners 33 one by one. The angle W between the connecting line between the two positioning holes 311a and the horizontal direction may be 5 degrees to 30 degrees.

[0062] See also Figures 1 to 6 , taking the case where there are two heating tubes 400 as an example for a brief description, the heating tube installation structure 100 is provided with two plug holes 20a and two elastic clips 31, and the plug holes 20a and the elastic clips 31 correspond to each other. The connecting wire 40 includes a wire body 41 and two wiring heads 42, and the two wiring heads 42 are respectively arranged at the opposite ends of the wire body 41 along the extension direction. The wire body 41 is fixed to the second wall plate 20 through the wire clip 21. The two wiring heads 42 correspond to the two plug holes 20a on the second wall plate 20 and are respectively connected to the two terminals 410 of the two heating tubes 400 close to the second wall plate 20, so as to connect the two heating tubes 400 in series. The conductive plug connectors 313 on the two elastic clips 31 are respectively connected to the positive and negative poles of the power supply through the power line 500, so that the two heating tubes 400 in series can be powered normally. It is understandable that due to the different numbers of heating tubes 400, the power supply circuit structure can be reasonably changed, and conventional adaptive changes should fall within the protection scope of this application, and this application will not go into details here.

[0063] In one embodiment, the first wall panel 10 has avoidance openings corresponding to the clamp seats 30 one by one. Each clamp seat 30 can be set on the side of the first wall panel 10 away from the second wall panel 20. Each avoidance opening avoids the corresponding clamp seat 30. When installing the heating pipe 400, it is necessary to pass the end of the heating pipe 400 away from the second wall panel 20 through the avoidance opening to connect the clamp seat 30.

[0064] It should be added that there may be multiple clamping seats 30 and each clamping seat 30 includes a bracket 32 ​​and an elastic clip 31, but the specific setting form is not limited to this. The clamping seat 30 can also be set to include a bracket 32 ​​and multiple elastic clips 31 corresponding one-to-one to the plug-in holes 20a, and the multiple elastic clips 31 are all arranged on the same bracket 32. In other words, the design purpose of the clamping seat 30 is to make the elastic clips 31 and the plug-in holes 20a correspond one-to-one, so the number of brackets 32 is not limited to one, and can also be other numbers.

[0065] In one embodiment, please refer to Figure 1 and Figure 2 The shell 200 has an inspection opening 200a, and each plug hole 20a is exposed at the inspection opening 200a. The oven also includes a cover plate 300, which can be opened and closed at the inspection opening 200a. When the heating pipe 400 needs to be removed, the cover plate 300 can be opened to pull out the heating pipe 400, thereby improving the convenience of disassembling and assembling the heating pipe 400.

[0066] In some other embodiments, the housing 200 may not be provided with the inspection port 200a. For example, when the heating tube 400 needs to be inspected or replaced, the entire housing 200 may be removed.
