Description

Technical Field

[0001] This utility model relates to the field of oven damper technology, and in particular to an oven damper switch with added indicator light device. Background Technology

[0002] The oven damper is an integral part of the oven. There are two types of dampers: mechanical dampers and electronic dampers. Mechanical dampers regulate airflow by adjusting the size of the opening, while electronic dampers control airflow by adjusting the speed of the exhaust fan. Both types of dampers regulate airflow, thereby affecting the temperature and humidity inside the oven.

[0003] There are two modes for opening the damper: one is manual opening and the other is a program-set automatic opening damper. Manually opened dampers require manual adjustment of the opening and closing mechanism as needed, while large ovens often have the damper opening and closing time set for automatic opening and closing.

[0004] However, the existing air damper is located at the top or back of the oven, making it difficult to observe after the air damper is opened. During the air damper opening process, there is a risk that the air damper may not open or may not open sufficiently, which may lead to abnormal product quality. Therefore, this application proposes an oven air damper switch with an indicator light device. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where the air vent is located at the top or back of the oven, making it difficult to observe after the air vent is opened, and the risk that the air vent may not open or may not open sufficiently during the air vent opening process, thus leading to abnormal product quality. The invention proposes an oven air vent switch with an indicator light device.

[0006] The technical solution of this utility model is as follows: A device for adding an indicator light to an oven damper switch includes an electrical control box. The electrical control box has ventilation holes inside. A damper plate is slidably connected to the top of the electrical control box near the ventilation holes. The damper plate is L-shaped. A hydraulic cylinder is fixedly connected to the top of the electrical control box near the damper plate. The output end of the hydraulic cylinder is fixedly connected to one side of the damper plate. A protective frame is slidably connected to the outside of the damper plate. The protective frame is fixedly connected to the top of the electrical control box. A limit switch is fixedly connected inside the protective frame away from the damper plate. The limit switch is fixedly connected inside the electrical control box.

[0007] Optionally, a cleaning cloth is abutted against the side of the damper plate away from the hydraulic cylinder. There are two cleaning cloths arranged symmetrically. An opening and closing plate is fixedly connected to the opposite side of the cleaning cloth. A rotating shaft is fixedly connected to one end of the opening and closing plate. The rotating shaft is rotatably connected to the inner side of the protective frame near the top.

[0008] Optionally, the opening and closing plate is hollow on the side away from the rotating shaft, a spring is fixedly connected to the side of the rotating shaft near the hollow, a push plate is fixedly connected to the end of the spring away from the rotating shaft, and an absorbent pad is fixedly connected to the end of the push plate away from the spring.

[0009] Optionally, a telescopic rod is fixedly connected to one side of the push plate and the opening / closing plate, and the telescopic rod is disposed inside the spring.

[0010] Optionally, the bottom of the electrical control box is fixedly connected to the oven body, the oven body is fixedly connected to a slide rail, and a baking tray is slidably connected inside the slide rail.

[0011] Optionally, the slide rails and baking trays are arranged in a linear array in multiple sets, and a control box is fixedly connected to one side of the oven body, with the top of the control box fixedly connected to the bottom of the electrical control box.

[0012] Optionally, the ventilation hole on the top of the electrical control box is connected to the interior of the oven body, and an exhaust pipe is fixedly connected to the top of the electrical control box, which is also connected to the interior of the oven body.

[0013] Optionally, a rotating rod is fixedly connected to one end of the rotating shaft, and a reset groove is provided on the protective frame near the rotating rod. A worm spring is provided inside the reset groove, with one end of the worm spring near the outside fixedly connected to the inside of the reset groove and the other end of the worm spring near the inside fixedly connected to the outside of the rotating rod.

[0014] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This device uses a hydraulic cylinder to push the damper plate into contact with the limit switch, so that the limit switch forms a passage and illuminates the indicator light, ensuring that the operator can observe whether the ventilation hole is fully opened at the first time. During the process of the damper plate and the limit switch being in contact, the cleaning cloth and water-absorbing pad can remove the water droplets condensed on one side of the damper plate and the side of the limit switch that needs to contact the damper plate. This solves the problem of inconvenience in observing whether the damper plate is fully open, and also solves the problem of temperature difference at the contact position between the damper plate and the limit switch, which easily causes water droplets to condense, thereby improving the service life of the damper plate and the limit switch.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 2 to 5 as well as Figure 9As shown, this utility model proposes a device for adding an indicator light to an oven damper switch, including an electrical control box 1. The electrical control box 1 has a ventilation hole 2 inside. A damper plate 3 is slidably connected to the top of the electrical control box 1 near the ventilation hole 2. The damper plate 3 is L-shaped. A hydraulic cylinder 4 is fixedly connected to the top of the electrical control box 1 near the damper plate 3. The output end of the hydraulic cylinder 4 is fixedly connected to one side of the damper plate 3. A protective frame 13 is slidably connected to the outside of the damper plate 3. The protective frame 13 is fixedly connected to the top of the electrical control box 1. A limit switch 11 is fixedly connected inside the protective frame 13 away from the damper plate 3. The device allows the damper plate 3 to contact the limit switch 11 via the hydraulic cylinder 4. The indicator light illuminates, and the limit switch 11 is fixedly connected inside the electrical control box 1. The circuits of the limit switch 11 are interconnected through the electrical control box 1. The damper plate 3 is abutted against the side away from the hydraulic cylinder 4 by a cleaning cloth 7. There are two cleaning cloths 7 arranged symmetrically. The opposite side of the cleaning cloth 7 is fixedly connected to the opening and closing plate 6. One end of the opening and closing plate 6 is fixedly connected to the rotating shaft 5. The rotating shaft 5 is rotatably connected to the inner side of the protective frame 13 near the top. When the hydraulic cylinder 4 pushes the damper plate 3 to contact the limit switch 11, the hydraulic cylinder 4 will drive the opening and closing plate 6 and the cleaning cloth 7 to rotate along the rotating shaft 5. The material of the cleaning cloth 7 can clean the water droplets adhering to the inner wall of the protective frame 13.

[0028] also Figure 5 and Figure 6 As shown, the side of the opening and closing plate 6 away from the rotating shaft 5 is hollow. A spring 8 is fixedly connected to the side of the rotating shaft 5 near the hollow side. A push plate 9 is fixedly connected to the end of the spring 8 away from the rotating shaft 5. A water-absorbing pad 10 is fixedly connected to the end of the push plate 9 away from the spring 8. The spring 8 can push the push plate 9 and the water-absorbing pad 10 to fit against the side of the limit switch 11, making it easy to clean the water droplets attached to the side of the limit switch 11. A telescopic rod 12 is fixedly connected to the opposite side of the push plate 9 and the opening and closing plate 6. The telescopic rod 12 is set inside the spring 8. When the spring 8 pushes the push plate 9 to extend or retract, the telescopic rod 12 can limit the extension or retraction of the push plate 9.

[0029] in addition Figure 1 and Figure 2As shown, the oven body 17 is fixedly connected to the bottom of the control box 1. The oven body 17 is fixedly connected to the slide rail 18. The baking tray 19 is slidably connected inside the slide rail 18. There are multiple sets of slide rail 18 and baking tray 19 arranged in a linear array. Multiple sets of baking trays 19 can bake various types of bread. The control box 20 is fixedly connected to one side of the oven body 17. The top of the control box 20 is fixedly connected to the bottom of the control box 1. The control box 20 can not only control the baking tray 19 to bake, but also control the hydraulic cylinder 4 to extend and retract the damper plate 3. The ventilation hole 2 opened on the top of the control box 1 is connected to the interior of the oven body 17. The exhaust pipe 21 is fixedly connected to the top of the control box 1. The exhaust pipe 21 is connected to the interior of the oven body 17. The exhaust pipe 21 can dissipate the heat and smoke from the baked bread inside the oven body 17.

[0030] In this embodiment, when the dough needs to be baked, the baking tray 19 is first removed from the oven body 17, and then the dough is placed on top of the baking tray 19. After that, the baking tray 19 can be reinstalled between the slide rails 18. The oven body 17 is controlled by the control box 20 to bake the dough. After baking for a certain period of time, the hydraulic cylinder 4 is needed to control the damper plate 3 to move, so that the damper plate 3 can be moved away from the ventilation hole 2. In this way, the water vapor and hot air inside the oven body 17 can be dissipated along the ventilation hole 2.

[0031] After the damper plate 3 is fully opened, it will abut against the limit switch 11, forming a passage for the limit switch 11. The indicator light will then light up, indicating that the ventilation hole 2 has been fully opened. If the indicator light does not light up, it means that the damper is not fully opened or not fully opened. In this case, it can be remedied by manually opening it.

[0032] When the equipment is running, the large temperature difference between the inside and outside will cause water droplets to condense on the opposite side of the limit switch 11 and the damper plate 3. When the damper plate 3 moves, it will first come into contact with the cleaning cloth 7. The material of the cleaning cloth 7 will first absorb the water droplets on the surface of the damper plate 3. As the damper plate 3 continues to move, it will push the opening and closing plate 6 and the rotating shaft 5 to rotate inside the protective frame 13. In this way, when the cleaning cloth 7 is fully opened, it can also clean the water droplets inside the protective frame 13. When the opening and closing plate 6 moves, the spring 8 and the telescopic rod 12 will drive the push plate 9 to move outward, so that the water absorption pad 10 is in contact with one side of the limit switch 11. As the water absorption pad 10 continues to move in contact with the limit switch 11, the water absorption pad 10 can clean the water droplets attached to one side of the limit switch 11.

[0033] After baking, the exhaust pipe 21 can dissipate all the smoke and heat inside the oven body 17. When the damper plate 3 moves backward, the opening and closing plate 6 will fall back to its original position due to gravity and reset. The above-mentioned circuit structure is achieved through... Figure 9The system is operated to ensure that the operating parameters at every point meet the baking conditions and temperature.

[0034] It should be noted that this device uses a hydraulic cylinder 4 to push the damper plate 3 into contact with the limit switch 11, causing the limit switch 11 to form a passage and illuminate the indicator light, ensuring that the operator can immediately observe whether the ventilation hole 2 is fully opened. During the process of the damper plate 3 and the limit switch 11 being in contact, the cleaning cloth 7 and the water-absorbing pad 10 can remove the water droplets condensed on one side of the damper plate 3 and the side of the limit switch 11 that needs to contact the damper plate 3. This solves the problem of not being able to easily observe whether the damper plate 3 is fully open, and also solves the problem of water droplets easily condensing due to the temperature difference at the contact point between the damper plate 3 and the limit switch 11, thus improving the service life of the damper plate 3 and the limit switch 11.

[0035] Example 2

[0036] like Figure 7 and Figure 8 As shown, based on Embodiment 1, a rotating rod 14 is fixedly connected to one end of the rotating shaft 5. A reset groove 16 is provided on the protective frame 13 near the rotating rod 14. The reset groove 16 facilitates the rotation of the rotating rod 14 inside it. A worm spring 15 is provided inside the reset groove 16. The outer end of the worm spring 15 is fixedly connected inside the reset groove 16, and the inner end of the worm spring 15 is fixedly connected to the outside of the rotating rod 14. The use of the worm spring 15 allows the rotating rod 14, the rotating shaft 5, and the opening and closing plate 6 to reset after the rotating rod 14 has rotated due to the elastic force of the worm spring 15.

[0037] In this embodiment, after the cleaning cloth 7 and the absorbent pad 10 are cleaned, the damper plate 3 will reset and move backward, and the worm spring 15 can drive the rotating rod 14 to reset and rotate inside the reset groove 16. In this way, the rotating rod 14 can drive the rotating shaft 5 and the opening and closing plate 6 to rotate to their original positions.

[0038] It should also be noted that the structure of the worm spring 15 used in this device can assist the rotation shaft 5 and the opening and closing plate 6 in resetting, which solves the problem that the opening and closing plate 6 is easily not reset completely by the single gravity method and will get stuck inside the protective frame 13, thus improving the stability of the opening and closing plate 6 when resetting.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
