Description

Technical Field

[0001] This utility model relates to the technical field of steam oven door locking structure, specifically a steam oven door locking mechanism. Background Technology

[0002] An electric steam oven is a kitchen appliance that converts water into high-temperature steam to cook food. It has a powerful pure steaming function, which can quickly perform cooking operations such as steaming vegetables, steaming rice, steaming soup, and heating food. It also has functions such as precise temperature control, locking in nutrients, reducing fat and salt, maintaining the original flavor of food, and making food full of freshness.

[0003] Existing electric steamers use lock cylinders and latches on the body and door to open and close the door. However, in actual use, the lock cylinder can easily disengage from the slot under external force, causing the door to separate from the body, resulting in accidental opening of the door and affecting the safety of production operations. Furthermore, after locking, the door is completely sealed and cannot release pressure, causing a large amount of hot steam to be generated when the door is opened, which can easily burn people. There are areas for improvement in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a steam oven door locking mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A steam oven door locking mechanism includes a body and a door installed at the front end of the body. A side plate is installed on the outer wall of one side of the front end of the door by a first bolt. A locking groove is provided on the front end of the side plate near the door. An installation groove is provided at the end of the door near the side plate. A first installation block is detachably installed in the installation groove. A second installation block is connected to the lower part of the first installation block near the side plate. A cylindrical hole and a storage groove are respectively provided at the front and rear parts of the second installation block. The rear end of the cylindrical hole is connected to the front end of the storage groove. The rear end of a right-angle handle is rotatably connected to the cylindrical hole and the storage groove. A locking block is vertically connected to the outer wall of the rear end of the right-angle handle. A torque spring is provided in the inner circumference of the middle part of the cylindrical hole. The two ends of the torque spring are connected to the inner wall of the cylindrical hole and the outer wall of the right-angle handle, respectively. A concave groove is provided in the middle of the right-angle handle, and a concave block is provided in the concave groove. The outer wall of the concave block away from the side plate is connected to the inner wall of the concave groove by several evenly distributed first springs. The inner wall of the front part of the cylindrical hole is provided with a positioning insertion hole that mates with the rear protruding end of the concave block. The front protruding end of the concave block extends to the outside of the right-angle handle. A pressure relief channel is provided on the upper part of the first mounting block. The bottom end of the pressure relief channel faces the inner cavity of the box, and the top end of the pressure relief channel faces the top end of the part of the first mounting block located in front of the box door. A pressure relief and exhaust assembly is installed at the top end of the first mounting block corresponding to the pressure relief channel.

[0006] As a further embodiment of this utility model: the top and bottom ends of the first mounting block are integrally formed with mounting plates, the mounting plates are installed in the mounting groove by second bolts, and a sealing sleeve is fitted around the part of the first mounting block that is inserted into the mounting groove.

[0007] As a further embodiment of this utility model: the pressure relief and exhaust assembly includes a fixed cylinder with its bottom end installed at the top of the pressure relief channel and a movable cylinder with its lower part inserted into the upper inner cavity of the fixed cylinder. A circular ring plate is connected to the inner wall of the middle part of the fixed cylinder, and the top end of the circular ring plate is connected to the bottom end of the movable cylinder through a second spring. An exhaust hole is provided at the rear of the middle part of the movable cylinder.

[0008] As a further improvement of this utility model: a counterweight cap is detachably installed at the top of the movable cylinder, and the counterweight cap is installed by means of a threaded connection.

[0009] As a further improvement of this utility model: the upper part of the pressure relief channel is vertically arranged, and the upper part of the pressure relief channel is inclined downward toward the inner cavity of the box.

[0010] This utility model has the following advantages: The steam oven door locking mechanism achieves rapid locking by driving the locking block to rotate and engage with the locking groove through a right-angle handle. Automatic reset via a torque spring ensures smooth operation. The concave block and positioning hole provide mechanical positioning in the locked state, preventing accidental loosening. Simultaneously, the buffer structure of the first spring reduces vibration. The user must first press the front protruding end of the concave block before grasping the right-angle handle to open the door. The force pressing the front protruding end of the concave block is in a different direction than the force rotating the right-angle handle, effectively preventing accidental opening of the door due to external force accidentally touching the right-angle handle, ensuring the safety of the door. The first mounting block is equipped with a pressure relief channel that works with the exhaust assembly to effectively release internal pressure. When the internal pressure is too high, pressure can be released through the door lock mechanism without opening the door, preventing a large amount of hot air from escaping after opening the door and avoiding the risk of high-pressure opening. The overall locking mechanism combines one-button locking stability, accidental opening safety, and pressure balance functions. The modular design facilitates disassembly and maintenance.

A cylindrical hole 501 and a storage groove 502 are respectively provided at the front and rear parts of the second installation block 5. The rear end of the cylindrical hole 501 is connected to the front end of the storage groove 502. The rear part of a right-angle handle 6 is rotatably connected to both the cylindrical hole 501 and the storage groove 502. A locking block 605 is vertically connected to the outer wall of the rear end of the right-angle handle 6. A torque spring 604 is provided in the inner circumference of the middle part of the cylindrical hole 501. The two ends of the torque spring 604 are respectively connected to... The inner wall of the cylindrical hole 501 is connected to the outer wall of the right-angle handle 6. A concave groove 601 is provided in the middle of the right-angle handle 6. A concave block 603 is provided within the concave groove 601. The outer wall of the concave block 603, away from the side plate 3, is connected to the inner wall of the concave groove 601 by several evenly distributed first springs 602. A positioning insertion hole 503 is provided on the inner wall of the front side of the cylindrical hole 501, which mates with the rear protruding end of the concave block 603. The front protruding end of 603 extends to the outside of the right-angle handle 6. A pressure relief channel 403 is provided on the upper part of the first mounting block 4. The bottom end of the pressure relief channel 403 faces the inner cavity of the box 1, and the top end of the pressure relief channel 403 faces the top end of the part of the first mounting block 4 located in front of the box door 2. A pressure relief and exhaust assembly 7 is installed at the position corresponding to the pressure relief channel 403 at the top end of the first mounting block 4. The pressure relief and exhaust assembly 7 automatically opens when the pressure in the inner cavity of the box 1 is too high.

[0021] Please see Figure 1 , Figure 2 The first mounting block 4 has an integrally formed mounting plate 401 at both its top and bottom ends. The mounting plate 401 is installed in the mounting groove 201 by a second bolt 402. A sealing sleeve 202 is fitted around the part of the first mounting block 4 that is inserted into the mounting groove 201.

[0022] Please see Figures 1 to 3The pressure relief and exhaust assembly 7 includes a fixed cylinder 701 with its bottom end installed at the top of the pressure relief channel 403 and a movable cylinder 702 with its lower part inserted into the upper inner cavity of the fixed cylinder 701. A circular ring plate 703 is connected to the middle inner wall of the fixed cylinder 701. The top end of the circular ring plate 703 is connected to the bottom end of the movable cylinder 702 through a second spring 704. The outer wall of the movable cylinder 702 slides against the inner wall of the fixed cylinder 701. The fixed cylinder 701 and the movable cylinder 702 are made of an alloy material with a low coefficient of surface friction. The bottom of both the annular plate 703 and the movable cylinder 702 is provided with hanging holes. The two ends of the second spring 704 are equipped with hooks. The second spring 704 can be installed by the hooks cooperating with the hanging holes. The bottom end of the fixed cylinder 701 can be installed to the top of the first mounting block 4 with screws through a structure such as a flange. The middle rear of the movable cylinder 702 is provided with an exhaust hole 705 facing the door 2. The exhaust hot air blows towards the door 2 and diffuses along the surface of the door 2, so as not to burn the person standing in front of the door 2.

[0023] Example 2: See Figure 2 , Figure 3 Based on Embodiment 1, a counterweight cap 706 is detachably installed on the top of the movable cylinder 702. The counterweight cap 706 is installed by means of threaded connection. The counterweight cap 706 cooperates with the second spring 704 to adjust the pressure capacity of the movable cylinder 702. When the pressure inside the box 1 is too high, the movable cylinder 702 and the counterweight cap 706 will be pushed upward.

[0024] Please see Figure 2 The upper part of the pressure relief channel 403 is vertically arranged, and the upper part of the pressure relief channel 403 is inclined downward toward the inner cavity of the box body 1, so that the condensate of the pressure relief channel 403 can flow down to the inner wall of the box door 2, and finally fall down together with other condensate on the inner wall of the box door 2 into the condensate collection tank at the bottom of the box door 2 for collection.

[0025] Working principle: When in use, hold the front of the right-angle handle 6 and press the front protruding end of the concave block 603 with your thumb. This will cause the rear protruding end of the concave block 603 to retract into the concave groove 601. Only then can the right-angle handle 6 be rotated. When the front of the right-angle handle 6 is rotated to a vertical position, the locking block 605 will rotate and retract into the storage groove 502. At this time, close the door 2 and rotate the right-angle handle 6 counterclockwise to keep the front of the right-angle handle 6 horizontal. The locking block 605 will then rotate and engage in the locking groove 301, locking the door 2. After releasing your thumb, the first... Spring 602 drives concave block 603 to reset. The protruding rear end of concave block 603 is inserted into positioning hole 503. At this time, right-angle handle 6 cannot be rotated. In this way, the right-angle handle 6 will not accidentally open the door 2 when it is accidentally hit by external force. When the pressure inside the body 1 of the electric steamer is too high, hot air will rise through pressure relief channel 403 and push the movable cylinder 702 until the exhaust hole 705 is pushed above the fixed cylinder 701. Excess hot air is discharged through exhaust hole 705 to relieve pressure on body 1 and ensure that a large amount of hot air will not rush out and burn people when the door 2 is opened.
