Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.
[0023] A double-layer vacuum insulation high-efficiency energy-saving refrigerator according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.
[0024] Example 1
[0025] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a double-layer vacuum insulation high-efficiency energy-saving refrigerator, including a cabinet body 1, a mounting groove is opened at the top of one side of the cabinet body 1, a door frame 2 is fixedly installed on the wall of the mounting groove, and a moving mechanism is arranged on one side of the door frame 2; the moving mechanism includes two mounting frames 7, a motor 8, a screw rod 9, two sliders 10, a mounting plate 11, a connecting rod 12 and a push plate 14, the two mounting frames 7 are fixedly installed on one side of the door frame 2, the motor 8 is fixedly installed on one side of the mounting frame 7, the output end of the motor 8 extends to the inside of the mounting frame 7, the screw rod 9 is fixedly installed on the output end of the motor 8, the two sliders 10 are threadedly connected to the outer wall of the screw rod 9, the mounting plate 11 is fixedly installed on one end of the corresponding slider 10, the connecting rod 12 is fixedly installed on one side of the mounting plate 11, and the push plate 14 is slidably installed on the outer wall of the connecting rod 12.
[0026] It should be noted that, by setting up a moving mechanism, when the first sliding door 3 and the second sliding door 4 are closed, the first sliding door 3 and the second sliding door 4 can be pressed against the two sides of the inner wall respectively by the push plate 14, thereby reducing the situation where the sliding door of the refrigerator is not closed tightly, and the energy-saving effect of the refrigerator can be increased; by setting up a motor 8, a servo motor can be selected for the motor 8, and the motor 8 controls the movement of the slider 10, and by setting up a push plate 14, the first baffle 5 and the second baffle 6 on the first sliding door 3 and the second sliding door 4 can be pushed.
[0027] In some embodiments, Figure 3As shown, the mounting frame 7 is located at both ends of one side of the door frame 2, two slide rails are fixedly installed on both sides of the inner wall of the door frame 2, the first sliding door 3 and the second sliding door 4 are slidably installed on the inner wall of the slide rails, and the first sliding door 3 and the second sliding door 4 are located between the two slide rails, and the first sliding door 3 and the second sliding door 4 are fixedly installed at the bottom and the top of one side of the first sliding door 3, and the second baffle 6 is fixedly installed at the bottom and the top of one side of the second sliding door 4.
[0028] It should be noted that, in this example, the first sliding door 3 and the second sliding door 4 can be vacuum glass doors, and infrared ranging sensors can be installed on both sides of the inner wall of the door frame 2 to detect whether the first sliding door 3 and the second sliding door 4 are tightly closed. The cabinet 1 can be a vacuum panel, and a double-layer vacuum space can be set inside the vacuum panel to increase the thermal insulation effect of the cabinet 1.
[0029] In this example, sealing strips are arranged around the outer walls of the first sliding door 3 and the second sliding door 4 for sealing between the first sliding door 3 and the second sliding door 4 and between the first sliding door 3 and the second sliding door 4 and the door frame 2 .
[0030] In some embodiments, Figure 2 As shown, the two push plates 14 correspond to the positions of the first baffle plate 5 and the second baffle plate 6, and the two push plates 14 are located between the corresponding first baffle plate 5 and the second baffle plate 6. An internal threaded hole is opened on one side of the slider 10, and the slider 10 is threadedly connected to the screw rod 9 through the internal threaded hole. The slider 10 is slidably installed on the inner wall of the installation frame 7.
[0031] It should be noted that the motor 8 starts to drive the screw rod 9 to rotate forward and reversely, and the screw rod 9 has opposite threads on both sides with the middle as the boundary. The two sliders 10 are respectively arranged at both ends of the screw rod 9. The rotation of the screw rod 9 can drive the two sliders 10 to move in opposite directions synchronously.
[0032] In this example, an existing compressor 16 is disposed inside the cabinet 1 , and a refrigeration copper tube 17 at one end of the compressor 16 extends into the cabinet 1 . When the compressor 16 is started, the cabinet 1 is cooled through the refrigeration copper tube 17 .
[0033] Example 2
[0034] In some embodiments, Figure 4 As shown, a fixed groove is opened on one side of the mounting plate 11, and a sensor 15 is fixedly installed on the wall of the fixed groove. A movable groove is opened on one side of the push plate 14, and the push plate 14 is slidably installed on the outer wall of the connecting rod 12 through the movable groove. A spring 13 is fixedly installed on one side of the mounting plate 11, and one end of the spring 13 is fixedly installed on one side of the mounting plate 11 on one side of the push plate 14.
[0035] It should be noted that when the push plate 14 pushes the first baffle plate 5 and the second baffle plate 6, the push plate 14 compresses the spring 13. At this time, the push plate 14 moves toward the mounting plate 11. The sensor 15 can use an infrared ranging sensor. When the push plate 14 drives the first sliding door 3 and the second sliding door 4 to press against the inner wall of the door frame 2, the push plate 14 is pressed tightly. At this time, the motor 8 reverses and drives the slider 10 back to the center of the screw rod 9, which is convenient for judging whether the first sliding door 3 and the second sliding door 4 are closed, reducing the possibility of the slider 10 and the screw rod 9 being stuck, and reducing damage to the motor 8.
[0036] The motor 8 in the present invention is a well-known component and will not be described in detail here.
[0037] Working principle: When opening or closing the first sliding door 3 and the second sliding door 4, the distance between the first sliding door 3 and the second sliding door 4 and the inner wall of the door frame 2 is detected by the infrared ranging sensor on the door frame 2. When the distance between one of the first sliding door 3 and the second sliding door 4 and the inner wall of the door frame 2 is greater than 5-10 cm, the motor 8 will not start. When the distance is less than 5-10 cm, the motor 8 will start, driving the slider 10 to move toward the first baffle 5 or the second baffle 6, pushing the first baffle 5 or the second baffle 6 to close.
[0038] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
