Description

Technical Field

[0001] This application relates to the field of ovens, specifically to an oven. Background Technology

[0002] In industrial production, ovens maintain their internal environment through high-temperature gas circulation. A common method of high-temperature gas circulation is to have the exhaust and intake ports on the same side; high-temperature gas is ejected from the exhaust port and then drawn in through the intake port. However, this gas circulation method has the following problems:

[0003] The negative pressure at the air intake will draw gas from inside the oven into the air intake, and the high-temperature gas ejected from the air outlet will also be drawn in by the air intake. This makes it difficult for the high-temperature gas to cover the side of the oven that is far from the air outlet and air intake. Specifically, for the transfer module located inside the oven, there will be a problem of uneven heating of the transferred workpiece. Utility Model Content

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] Furthermore, where the terms "first," "second," and "third" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," and "third" may explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 1-3 As shown, in some embodiments of this application, an oven is provided, including: a heating chamber body 2, which houses a transmission module 21, an intake duct 23, and an exhaust duct 12, located on opposite sides of the transmission module 21. High-temperature gas is ejected from the exhaust duct 12, and the intake duct 23 draws in gas from the heating chamber body 2. The separation of the intake duct 23 and exhaust duct 12 on opposite sides of the transmission module 21 creates an airflow from one side to the other on the transmission module 21. The heat transfer of the high-temperature gas ensures a uniform high-temperature environment around the transmission module 21, thereby ensuring uniform heating of the workpiece conveyed on the transmission module 21.

[0040] Furthermore, the heating chamber body 2 is also equipped with an air intake module 22, which is connected to the air intake duct 23 and the air outlet duct 12 to form a hot air path. The air intake module 22 has an air outlet and an air inlet. The air outlet of the air intake module 22 is connected to the air outlet duct 12, and the air inlet of the air intake module 22 is connected to the air intake duct 23. The air intake function of the air intake duct 23 and the air exhaust function of the air outlet duct 12 are realized through the same air intake module 22, simplifying the structure of the hot air path.

[0041] Meanwhile, the hot air path also includes a transition air passage 24, with its two ends connected to the intake air passage 23 and the intake module 22, respectively. The transition air passage 24 is located at the top of the housing space of the heating chamber body 2, and more specifically, the transition air passage 24 is arranged parallel to the transmission module 21. The heater 241 is housed within the transition air passage 24.

[0042] After the gas that has completed heat transfer is drawn into the intake duct 23, it is reheated by the heater 241 and then transported to the exhaust duct 12 via the intake module 22. It is then discharged back into the heating chamber body 2 to heat the internal environment temperature, thereby achieving cyclic heating.

[0043] In some embodiments of this application, the heating chamber body 2 is further equipped with a protective door 1, the door body 11 of which is rotatably mounted on the heating chamber body 2, allowing communication between the inside and outside of the heating chamber body 2. In this solution, combined with Figure 4 The exhaust duct 12 is installed on the door body 11. On the one hand, the exhaust duct 12, when attached to the door body 11, prevents the exhaust duct 12 from interfering with the door opening. On the other hand, when the door body 11 is opened, the exhaust duct 12 is disconnected from the intake module 22, which stops the transmission module 21 from ejecting high-temperature gas, facilitating the cooling of the transmission module 21 and making subsequent manual operation easier for the operator.

[0044] Specifically, an opening 1211 is provided at one end of the air outlet duct 12, and the opening 1211 is matched with the air outlet of the air intake module 22. The opening 1211 and the air outlet of the air intake module 22 are matched so that the opening 1211 is aligned, so that the air from the air outlet enters the air outlet duct 12 through the opening 1211.

[0045] In this design, since the protective door 1 needs to be opened and closed, the exhaust duct 12 disengages from the intake module 22 when opened, and reconnects to the intake module 22 when closed. To facilitate opening, a rigid connection structure is not feasible between the exhaust duct 12 and the intake module 22, while maintaining airtightness after closure. A sealing ring 1212 is provided around the circumferential outer edge of the opening 1211, pressing against the intake module 22. Utilizing the elasticity of the sealing ring 1212, it presses against the intake module 22, ensuring airtightness while facilitating the opening of the protective door 1 and allowing for rapid disengagement of the exhaust duct 12 from the intake module 22.

[0046] Furthermore, the air outlet duct 12 is connected to the door body 11 via a mounting bracket 13. In this design, the mounting bracket 13 is L-shaped, and its two vertical surfaces are respectively attached to and connected to the air outlet 12 and the door body 11. The mounting bracket 13 is provided with adjustment grooves, which are located on the two vertical surfaces, allowing the air outlet 12 to move relative to the door body 11.

[0047] The screw passes through the adjustment groove, which guides the air duct 12 and the mounting bracket 13 to adjust their positions along a straight line, while the air duct 12 can also be adjusted along another straight line. That is, the air duct 12 can be positioned relative to the door body 11 in two directions. Simultaneously, the screw also secures the position of the air duct 12. Through the cooperation of the screw and the adjustment groove, a precise connection between the air duct 12 and the circulating airflow channel can be ensured.

[0048] In some embodiments of this application, such as Figure 2 and combined Figure 5 , 6 As shown, the number of transmission modules 21 is at least two, and multiple transmission modules 21 are arranged vertically at intervals. The exhaust duct 12 is vertically arranged. The intake duct 23 is formed by the side wall 232 separating the accommodating space in the heating box body 2. The side wall 232 is provided with air holes 2323 to increase the gas absorption efficiency of the intake duct 23.

[0049] Specifically, the heating chamber body 2 is supported by a bracket to form its structural shape. The side wall 232 is connected to the bracket, so that the side wall 232 and part of the inner wall of the heating chamber body 2 form a negative pressure cavity 231. The air intake module 22 is connected to the negative pressure cavity 231, and multiple air holes 2323 are connected to the negative pressure cavity 231, thereby creating a negative pressure at the air holes 2323 to draw in the gas inside the heating chamber body 2.

[0050] Furthermore, the area of ​​the vents 2323 on the sidewall 232 can be adjusted, thereby controlling the suction force of the vents 2323. It should be noted that the area of ​​the air inlet on the air outlet duct 12 can also be adjusted, thereby controlling the airflow speed. Since the adjustment principle of the vents 2323 and the air inlet is the same, the following explanation uses the vents 2323 on the sidewall 232 as an example. The sidewall 232 includes a base plate 2321 and an adjustment plate 2322 that moves relative to the base plate 2321. The base plate 2321 and the adjustment plate 2322 have several overlapping openings to form vents 2323.

[0051] In this scheme, since the adjustment plate 2322 can move relative to the substrate 2321, the overlapping area of ​​the two openings changes, which in turn changes the cross-sectional area through which the gas passes through the vent 2323. Under the premise that the power of the suction module 22 remains unchanged, the reduction in the cross-sectional area through which the gas passes through the vent 2323 will increase the suction force of the vent 2323. It is understandable that since the transmission modules 21 are arranged vertically, there are differences in the distance between the suction module 22 and each transmission module 21. The vents 2323 connected to the negative pressure chamber 231 have a higher negative pressure closer to the suction module 22 and a lower negative pressure further away from the suction module 22. In order to ensure that the negative pressure formed at each vent 2323 is basically consistent, it is necessary to adjust the cross-sectional area of ​​the vents 2323 further away from the suction module 22 to increase the suction force.

[0052] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
