Description

Technical Field

[0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator with a photoelectric liquid level sensor. Background Art

[0002] The core feature of the photoelectric liquid level sensor refrigerator is that it uses a photoelectric liquid level sensor for liquid level detection. This sensor has the advantages of high precision, fast response speed, and strong anti-interference ability. It can monitor the changes in the water tank or refrigerant level inside the refrigerator in real time and accurately. In the refrigerator, the photoelectric liquid level sensor is usually installed on the refrigerant container whose liquid level needs to be monitored. When the liquid level changes, the sensor will immediately detect it and send a signal. After receiving the signal, the control system will perform corresponding processing according to the preset logic, such as alarm, automatic water replenishment or adjustment of the refrigeration system.

[0003] Within the current technical scope, photoelectric liquid level sensors are generally installed on containers by bolting. Although this installation method is firm, in actual applications, especially when subsequent maintenance or overhaul is required, the photoelectric liquid level sensor located inside the refrigerator becomes extremely cumbersome and challenging to disassemble due to the particularity of its installation location. It is not only time-consuming and labor-intensive, but also very easy to cause accidental damage to the sensor or its peripheral components during operation.

A transparent protective window is installed on the assembly component, so that the transparent protective window can be driven to move to the front of the photoelectric liquid level sensor body to protect the probe of the photoelectric liquid level sensor body. By adding a protective structure to the lens of the photoelectric liquid level sensor body, physical damage such as scratches and impacts during the disassembly and assembly process can be effectively prevented, thereby protecting the optical elements of the sensor from being affected, ensuring that its detection accuracy is not damaged, and maintaining a high level of performance.

When one side of the positioning frame 10 leaves the positioning groove 9, the spring 182 recovers its deformation, so that the push plate 183 returns to the initial position, and the refrigerator sealing plate 3 is pushed to move by the push plate 183, so that a part of it extends out of the refrigerant container cavity 2, thereby facilitating the staff to remove the refrigerator sealing plate 3.

[0036] The working principle of the present invention is: when installing the photoelectric liquid level sensor body 4, the first driving motor 61 is driven, and the first chain belt 63 is used to drive and connect the first active sprocket 62 and the first driven sprocket 64, thereby driving the first screw rods 65 on both sides to rotate synchronously, thereby driving the moving block 71 in the first slide groove 8 to move, so that the moving block 71 drives the connecting rod 72 to move, and the connecting rod 72 drives the assembly plate 73 to move, so that the transparent protective window 5 of the assembly plate 73 moves to the lens of the photoelectric liquid level sensor body 4, and the probe of the photoelectric liquid level sensor body 4 is protected. The lens of the photoelectric liquid level sensor body 4 is provided with a protective structure, which can effectively prevent physical damage such as scratches and impacts during the disassembly and assembly process, thereby protecting the optical elements of the sensor from being affected, ensuring that its detection accuracy is not damaged, and ensuring that the photoelectric liquid level sensor body 4 is safer when used and avoids interference from external factors. Then, the refrigerator sealing plate 3 is installed in the refrigerant container cavity 2, and the refrigerator sealing plate 3 is pushed. The refrigerator sealing plate 3 squeezes the push plate 183, and the spring 182 connected to the push plate 183 is deformed, so that the push plate 183 shrinks into the groove 181. At this time, the embedded block 16 and the embedded groove 1 7 is connected, and the installation position of the refrigerator sealing plate 3 is limited under the action of the limit frame 15. After the position of the refrigerator sealing plate 3 is determined, the positioning frame 10 is driven to move by the second power mechanism 11, so that one side of the positioning frame 10 is inserted into the positioning groove 9 of the refrigerator sealing plate 3, and the refrigerator sealing plate 3 can be fixed. At this time, the photoelectric liquid level sensor body 4 is located inside the refrigerant container cavity 2 to monitor the solution inside the refrigerant container cavity 2. When the photoelectric liquid level sensor needs to be maintained, the second driving motor 111 is used to drive the second active sprocket 112 to rotate, and the second active sprocket 112 is driven by the second driving motor 111 to rotate. The second chain belt 113 drives the second driven sprocket 114 to rotate, thereby driving the second screw rod 115 to rotate, providing power for the movement of the positioning frame 10, so that the positioning frame 10 leaves the positioning groove 9. At this time, the refrigerator cover 3 is no longer fixed. When one side of the positioning frame 10 leaves the positioning groove 9, the spring 182 recovers its deformation, so that the push plate 183 returns to its initial position, and the push plate 183 pushes the refrigerator cover 3 to move, so that a part of it extends out of the refrigerant container cavity 2, thereby facilitating the staff to remove the refrigerator cover 3, and then facilitating the maintenance of the photoelectric liquid level sensor body 4 on the outside of the refrigerator body 1.
