Technical Field

[0001] The utility model relates to the technical field of bread oven doors, and specifically to a heat-insulating door body structure for the inlet and outlet of a bread oven. Background Technique

[0002] A bread baking oven is a special oven for baking bread. When putting the product to be baked into the bread oven, the oven door needs to be opened and closed. In order to ensure that the internal temperature is sufficient during baking, a heat-insulating door body structure for the inlet and outlet of the bread oven is required to prevent the internal temperature from leaking out and causing abnormal baking.

[0003] According to a pull rod device of a bread baking oven door disclosed on the patent network (authorization announcement number: CN 219711290 U), it is described that "the utility model relates to the technical field of bread baking oven doors, and discloses a pull rod device of a bread baking oven door, including an oven main body, a door frame is arranged on the front side of the oven main body, an oven door is embedded in the door frame, rotating shafts are fixedly connected to both sides of the lower end of the oven door, hooks are fixedly connected to the surfaces of the rotating shafts, a first articulated shaft is hinged to the end of the hook, a connecting piece is fixedly connected to the surface of the first articulated shaft, a second articulated shaft is fixedly connected to the upper end of the connecting piece, a spring is hung on the waist of the second articulated shaft, and an anti-collision air cushion is arranged on the inner side of the oven door. By setting the anti-collision air cushion, when the oven door is closed, the impact force between the oven door and the front side of the oven main body will be reduced, and under the action of the exhaust holes and exhaust grooves, the air inside the anti-collision air cushion will be discharged, so that the oven door will not make a loud noise when closed. At the same time, under the pulling force of the spring, the anti-collision air cushion will be closely attached to the front side wall of the oven main body."

[0004] Regarding the above description content, the applicant believes that there are the following problems:

[0005] During the use of this utility model, by closely attaching the anti-collision air cushion to the front side wall of the oven main body, the baking temperature inside the oven main body is ensured, and the oven door will not make a loud noise when closed. However, in actual use, when the oven door is opened to replace the product to be baked, the spring is stretched, so that when the oven door is accidentally touched, the oven door is likely to be suddenly closed, causing injury to the operator. Therefore, it is necessary to improve a heat-insulating door body structure for the inlet and outlet of a bread oven to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a heat-insulating door body structure for the inlet and outlet of a bread oven to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A heat-insulating door body structure for the inlet and outlet of a bread oven, including an oven body. Four corners of the bottom of the oven body are fixedly installed with support columns. A display screen is arranged on the front of the oven body. Buttons are arranged on the front of the oven body. A door body mechanism is arranged on the front of the oven body. A storage mechanism is arranged inside the door body mechanism.

[0008] The door body mechanism includes a switch component and an anti-misoperation component. The anti-misoperation component is arranged inside the switch component.

[0009] Preferably, the switch component includes two columns. The columns are fixedly installed on the front of the oven body. A rotating shaft A is rotatably installed inside the columns. A heat-insulating door body is fixedly installed outside the rotating shaft A. An observation window is arranged inside the heat-insulating door body. A convex block A is fixedly installed inside the columns. A movable column A is rotatably installed inside the convex block A. A spring A is fixedly installed outside the movable column A. Two convex blocks B are fixedly installed outside the rotating shaft A. A movable column B is rotatably installed inside the convex block B. The rotation of the movable column B enables the spring A to be stretched while ensuring that the movable column B and the spring A are in the same plane, preventing the deformation of the spring A and increasing the service life of the device.

[0010] Preferably, one end of the spring A away from the movable column A is fixedly installed with the movable column B. The convex block B is movably installed inside the column. When the convex block B rotates, the movable column B rotates to stretch the spring A.

[0011] Preferably, the anti-misoperation component includes a fixed sleeve. The fixed sleeve is fixedly installed inside the right column. A sliding column is slidably installed inside the fixed sleeve. A spring B is fixedly installed inside the column. A pull block is slidably installed inside the right column. A rectangular plate is fixedly installed inside the pull block. A plug column is fixedly installed on the left side of the rectangular plate. The plug column is inserted into the heat-insulating door body, avoiding the problem that when the oven door is accidentally touched, the oven door is likely to be suddenly closed, causing injury to the operator.

[0012] Preferably, the plug column is inserted into the heat-insulating door body. The rectangular plate is fixedly installed with the sliding column. One end of the spring B away from the column is fixedly installed with the rectangular plate. The spring B drives the rectangular plate to move leftward, so that the plug column is inserted into the heat-insulating door body.

[0013] Preferably, the storage mechanism includes spring C, which is fixedly installed inside the heat-insulating door body. One end of spring C away from the heat-insulating door body is fixedly installed with a handle, and an anti-detachment block is fixedly installed on the outside of the handle. Spring D is fixedly installed inside the heat-insulating door body. One end of spring D away from the heat-insulating door body is fixedly installed with a top block. A rotating shaft B is rotatably installed inside the heat-insulating door body. A worm gear is fixedly installed on the outside of rotating shaft B. Two rings are fixedly installed on the outside of rotating shaft B. A pulling rope is fixedly installed on the outside of rotating shaft B. A worm is rotatably installed inside the heat-insulating door body, and the worm meshes with the worm gear to drive the rotation of rotating shaft B.

[0014] Preferably, the worm meshes with the worm gear. One end of the pulling rope away from rotating shaft B is fixedly installed with the top of the top block. The top block contacts the handle, and the contact between the top block and the handle drives the handle to extend out of the heat-insulating door body. Pulling the handle can open the heat-insulating door body.

[0015] Compared with the prior art, the present utility model provides a heat-insulating door body structure for the inlet and outlet of a bread oven, having the following beneficial effects:

[0016] 1. For the heat-insulating door body structure of the inlet and outlet of this bread oven, pulling the handle causes the heat-insulating door body to rotate, driving the rotation of rotating shaft A, driving the rotation of convex block B, and the rotation of movable column B causes spring A to be stretched while ensuring that movable column B and spring A are in the same plane, preventing spring A from deforming and increasing the service life of the device. After the heat-insulating door body rotates to 90 degrees, spring B drives the rectangular plate to move leftward, causing the insertion post to be inserted into the heat-insulating door body, avoiding the problem that when accidentally touching the oven door, the oven door is likely to suddenly close, causing injury to the operator. After placing the item, moving the pull block to the right drives the rectangular plate to move, driving the insertion post to disengage from the heat-insulating door body. Gently lifting the handle causes the heat-insulating door body to approach the furnace body under the action of spring A to close the door, making the closure tight and preventing heat from escaping.

[0017] 2. For the heat-insulating door body structure of the inlet and outlet of this bread oven, rotating the worm to mesh with the worm gear drives the rotation of rotating shaft B, thereby driving the pulling rope to pull the top block to slide inside the heat-insulating door body, contacting the handle and driving the handle to extend out of the heat-insulating door body. Pulling the handle can open the heat-insulating door body. When not in use, rotating the worm causes the pulling rope to relax and not pull the top block, causing the top block to descend under the action of spring D and not push out the handle, causing the handle to retract inside the heat-insulating door body under the pulling force of spring C, making the device reduce the placement space and be convenient for storage when not in use, and preventing the handle from being knocked and protecting it.

Pulling the handle 62 can open the heat preservation door body 513.

[0035] During the actual operation process, when this device is in use, the rotating worm 610 meshes with the worm gear 67, driving the rotating shaft B66 to rotate, thereby driving the pull rope 69 to pull the top block 65 to slide inside the heat preservation door body 513, contacting the handle 62 to drive the handle 62 to extend out of the heat preservation door body 513. Pulling the handle 62 can open the heat preservation door body 513. When not in use, rotating the worm 610 causes the pull rope 69 to relax and not pull the top block 65, so that the top block 65 descends under the action of the spring D64 and does not eject the handle 62, making the handle 62 retract inside the heat preservation door body 513 under the pulling force of the spring C61. This enables the device to reduce the placement space when not in use, facilitating storage, and preventing the handle 62 from being knocked, providing protection for it. Pulling the handle 62 causes the heat preservation door body 513 to rotate, driving the rotating shaft A512 to rotate, driving the convex block B518 to rotate, and the movable column B519 to rotate, causing the spring A517 to be stretched while ensuring that the movable column B519 and the spring A517 are in the same plane, preventing the spring A517 from deforming and increasing the service life of the device. After the heat preservation door body 513 rotates to 90 degrees, the spring B523 drives the rectangular plate 525 to move leftward, causing the plug post 526 to be inserted inside the heat preservation door body 513, avoiding the problem that when accidentally touching the oven door, it is easy to cause the sudden closing of the oven door and pinching the operator. After placement, moving the pull block 524 to the right drives the rectangular plate 525 to move, driving the plug post 526 to disengage from the heat preservation door body 513. Gently lifting the handle 62 causes the heat preservation door body 513 to approach the furnace body 1 under the action of the spring A517 to close the door tightly, preventing heat from escaping.
