Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of refrigerator sliding door defogging switch, and particularly relates to refrigerator sliding door defogging switch. Background Technology
[0002] Refrigerators are used in restaurants to store food for easy selection by customers. However, when in use, the glass doors of refrigerated display cases are prone to fogging, which can obstruct the view and make it difficult for customers to see the products inside, thus affecting the shopping experience.
[0003] While some existing freezers can defog, the defogger is always on. During peak restaurant seasons, many customers frequently open and close the freezer door. The defogger operates continuously when the door is open, consuming energy as it needs to constantly work to prevent condensation from forming on the door and other parts of the freezer. Furthermore, the entry of warm, humid air from outside increases the difficulty and workload of defogging, further increasing energy consumption. Additionally, customers often close the freezer door hastily after selecting their food, resulting in a loose seal. Therefore, we propose a defogger switch for the sliding door of the freezer. Utility Model Content
[0004] The purpose of this invention is to provide a defrost switch for a refrigerator sliding door to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a defrosting switch for a refrigerator sliding door, comprising a refrigerator and a defroster, wherein the defroster is fixedly installed inside the refrigerator, and further comprising:
[0006] A door frame is fixedly installed inside the freezer. Two sliding grooves are provided in the door frame. A sliding door is slidably installed in each of the two sliding grooves. A first sealing ring is fixedly installed on the side of the two sliding doors that are far apart from each other. A first magnet is fixedly installed on the sliding door and inside the first sealing ring. A second sealing ring is fixedly installed in the sliding groove and inside the second sealing ring.
[0007] Two grooves are provided, both of which are located inside the door frame and at the bottom of two sliding grooves respectively. A cylinder is fixedly installed in each groove, and a torsion spring is sleeved on the cylinder. A rotating plate is rotatably installed in the groove and at the top of the torsion spring. A second conductive block is fixedly installed in the groove, and a first conductive block that contacts the second conductive block is fixedly installed at the bottom of the rotating plate.
[0008] In this technical solution, during use, the operator can plug the refrigerator into the socket. At this time, one of the second conductive blocks and one of the first conductive blocks will be energized. Because the two first conductive blocks are electrically connected, the other first conductive block will energize the other second conductive block, which will then energize and operate the demister, thereby defogging the refrigerator. When the operator opens the sliding door, the sliding door will slide in the sliding groove. At this time, the first magnet on the sliding door will separate from the second magnet in the sliding groove and will no longer be magnetically connected. Subsequently, when the top of the sliding door is no longer in contact with the top of the rotating plate, under the torsional force of the torsion spring, the rotating plate will rotate in the groove. The rotating plate will drive the first conductive block to rotate upward, so that the first conductive block and the second conductive block are no longer in contact, thereby de-energizing the demister. This process de-energizes the demister as long as one sliding door is opened. The demister will only be energized and started when both sliding doors are closed.
[0009] When the two sliding doors are closed, the first magnet on the sliding door will be magnetically attracted to the corresponding second magnet. At this time, the first sealing ring on the sliding door will be in close contact with the corresponding second sealing ring, and the rubber pads at the overlapping positions of the two sliding doors will contact each other to increase the overall sealing of the device. At this time, the rotating plate will rotate due to the pressure of the sliding door. The rotating plate will drive the first conductive block to rotate downward, so that the first conductive block contacts the second conductive block. At this time, the two first conductive blocks will contact the two second conductive blocks respectively. The top of the rotating plate contacts the bottom of the sliding door, so that the plug, the two first conductive blocks and the two second conductive blocks are connected in series, thereby enabling the demister to be powered on and started.
[0010] In the above technical solution, the first magnet on the sliding door is magnetically connected to the second magnet in the corresponding sliding groove, and the first sealing ring on the sliding door is in close contact with the second sealing ring in the corresponding sliding groove.
[0011] In this technical solution, the first magnet can be magnetically connected to the second magnet, thereby ensuring that the sliding door is closed tightly. Under the action of the first sealing ring and the second sealing ring, the sealing performance of the entire device can be increased.
[0012] In the above technical solution, the top of the rotating plate contacts the bottom of the sliding door.
[0013] In this technical solution, it is ensured that the sliding door can drive the rotating plate to rotate when it is moved to the top of the rotating plate.
[0014] In the above technical solution, furthermore, the two ends of the torsion spring are tightly welded to the bottom of the rotating plate and the inner wall of the groove, respectively.
[0015] In this technical solution, the structural stability of the torsion spring is ensured.
[0016] In the above technical solution, further, the demister is electrically connected to one of the second conductive blocks, and the two first conductive blocks are electrically connected.
[0017] In this technical solution, it is ensured that one of the second conductive blocks can provide power to the demister after being energized, and that one of the first conductive blocks can be energized after being energized, which in turn enables the other first conductive block to be energized.
[0018] In the above technical solution, a sealing gasket is further fixedly installed at the overlapping positions of the two sliding doors.
[0019] In this technical solution, the sealing gasket ensures a strong seal at the overlapping position of the two sliding doors.
[0020] In the above technical solution, the positions of the two sliding doors are further staggered.
[0021] In this technical solution, it is ensured that the two sliding doors can slide open left and right.
[0022] Furthermore, in the above technical solution, a handle is fixedly installed on the sliding door.
[0023] In this technical solution, it is ensured that customers can open the sliding door by holding the handle.
[0024] The beneficial effects of this utility model are:
[0025] 1. The defrost switch for the sliding door of the freezer, through the cooperation of the first magnet, the first sealing ring, the second magnet and the second sealing ring, and the magnetic attraction between the first magnet and the second magnet, allows the first magnet on the back of the sliding door to actively move toward the position of the second magnet when it approaches the second magnet, thereby ensuring that the sliding door closes tightly and preventing outside air from entering the freezer if the sliding door is not closed tightly.
[0026] 2. The defrost switch for the sliding door of this refrigerator, through the cooperation of the groove, the second conductive block, the first conductive block, the rotating plate, the torsion spring, the cylinder and the sliding door, ensures that the defrost is de-energized when the sliding door is opened, thereby avoiding increased defrosting difficulty and workload when the sliding door is opened, and preventing further increase in energy consumption.

[0037] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.
[0038] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0039] Example 1: This example provides a defrost switch for a refrigerator sliding door, including a refrigerator 1 and a defrost 3. The defrost 3 is fixedly installed inside the refrigerator 1, and also includes:
[0040] Door frame 4 is fixedly installed inside the freezer 1. Two sliding grooves 8 are opened in the door frame 4. Sliding doors 2 are slidably installed in both sliding grooves 8. A first sealing ring 6 is fixedly installed on the side of the two sliding doors 2 that is far apart from each other. A first magnet 5 is fixedly installed on the sliding door 2 and inside the first sealing ring 6. A second sealing ring 10 is fixedly installed in the sliding groove 8 and inside the second sealing ring 10. A second magnet 7 is fixedly installed in the sliding groove 8 and inside the second sealing ring 10.
[0041] Two grooves 15 are formed inside the door frame 4 and are located at the bottom of two sliding grooves 8 respectively. A cylinder 12 is fixedly installed in the groove 15, and a torsion spring 11 is sleeved on the cylinder 12. A rotating plate 14 is rotatably installed in the groove 15 and on top of the torsion spring 11. A second conductive block 13 is fixedly installed in the groove 15, and a first conductive block 9 that contacts the second conductive block 13 is fixedly installed at the bottom of the rotating plate 14.
[0042] In operation, the operator plugs the power cord of the freezer 1 into the socket. This energizes one of the second conductive blocks 13 and one of the first conductive blocks 9. Because the two first conductive blocks 9 are electrically connected, the other first conductive block 9 energizes the other second conductive block 13, which in turn energizes and operates the demister 3, thus defogging the interior of the freezer 1. When the operator opens the sliding door 2, it slides within the sliding groove 8. At this time, the first magnet on the sliding door 2... Iron 5 will separate from the second magnet 7 in the sliding groove 8 and no longer be magnetically connected. Then, when the top of the sliding door 2 is no longer in contact with the top of the rotating plate 14, under the torsional force of the torsion spring 11, the rotating plate 14 will rotate in the groove 15. The rotating plate 14 will drive the first conductive block 9 to rotate upward, so that the first conductive block 9 and the second conductive block 13 are no longer in contact, thereby de-energizing the demister 3. This process will de-energize the demister 3 as long as one sliding door 2 is opened. The demister 3 will only be energized and started when both sliding doors 2 are closed.
[0043] When the two sliding doors 2 are closed, the first magnet 5 on the sliding door 2 will be magnetically connected to the corresponding second magnet 7. At this time, the first sealing ring 6 on the sliding door 2 will be in close contact with the corresponding second sealing ring 10, and the rubber pads at the overlapping positions of the two sliding doors 2 will contact each other to increase the sealing of the overall device. At this time, the rotating plate 14 will rotate due to the pressure of the sliding door 2. The rotating plate 14 will drive the first conductive block 9 to rotate downward, so that the first conductive block 9 contacts the second conductive block 13. At this time, the two first conductive blocks 9 will contact the two second conductive blocks 13 respectively. The top of the rotating plate 14 contacts the bottom of the sliding door 2, so that the plug, the two first conductive blocks 9 and the two second conductive blocks 13 are connected in series, thereby enabling the demister 3 to be powered on and started.
[0044] Example 2: This example provides a defrosting switch for a refrigerator sliding door. In addition to the technical solutions described in the above examples, it also features the following technical characteristics: the first magnet 5 on the sliding door 2 is magnetically connected to the second magnet 7 in the corresponding sliding groove 8; and the first sealing ring 6 on the sliding door 2 is in close contact with the second sealing ring 10 in the corresponding sliding groove 8. Ensuring that the first magnet 5 can magnetically connect with the second magnet 7 ensures that the sliding door 2 is closed tightly. The action of the first sealing ring 6 and the second sealing ring 10 increases the overall sealing performance of the device.
[0045] Example 3: This example provides a defrost switch for a refrigerator sliding door. In addition to the technical solutions of the above examples, it also has the following technical features: the top of the rotating plate 14 contacts the bottom of the sliding door 2. This ensures that when the sliding door 2 is moved to the top of the rotating plate 14, it can drive the rotating plate 14 to rotate.
[0046] Example 4: This example provides a defrost switch for a refrigerator sliding door. In addition to the technical solutions of the above examples, it also has the following technical features: the two ends of the torsion spring 11 are tightly welded to the bottom of the rotating plate 14 and the inner wall of the groove 15, respectively. This ensures the structural stability of the torsion spring 11.
[0047] Example 5: This example provides a defrost switch for a refrigerator sliding door. In addition to the technical solutions of the above examples, it also has the following technical features: the defrost 3 is electrically connected to one of the second conductive blocks 13, and the two first conductive blocks 9 are electrically connected. Specifically, it ensures that energizing one of the second conductive blocks 13 provides power to the defrost 3, and that energizing one of the first conductive blocks 9 enables the other first conductive block 9 to be energized.
[0048] Example 6: This example provides a defrost switch for a refrigerator sliding door. In addition to the technical solutions described in the above examples, it also features the following technical characteristics: sealing gaskets are fixedly installed at the overlapping positions of the two sliding doors 2. These sealing gaskets ensure a strong seal at the overlapping positions of the two sliding doors 2.
[0049] Example 7: This example provides a defrost switch for a refrigerator sliding door. In addition to the technical solutions described in the above examples, it also has the following technical features: the positions of the two sliding doors 2 are staggered. This ensures that the two sliding doors 2 can slide open left and right.
[0050] Example 8: This example provides a defrost switch for a refrigerator sliding door. In addition to the technical solutions described in the above examples, it also has the following technical features: a handle is fixedly installed on the sliding door 2. This ensures that customers can easily open the sliding door 2 by holding the handle.
[0051] Working principle: During use, the operator can plug the power cord of the freezer 1 into the socket. At this time, one of the second conductive blocks 13 will be energized, and one of the first conductive blocks 9 will be energized. Because the two first conductive blocks 9 are electrically connected, the other first conductive block 9 will energize the other second conductive block 13, which will then energize and operate the demister 3, thereby defogging the inside of the freezer 1. When the operator opens the sliding door 2, the sliding door 2 will slide within the sliding groove 8. At this time, the first conductive block 9 on the sliding door 2... Magnet 5 will separate from the second magnet 7 in the sliding groove 8 and will no longer be magnetically connected. Then, when the top of the sliding door 2 is no longer in contact with the top of the rotating plate 14, under the torsional force of the torsion spring 11, the rotating plate 14 will rotate in the groove 15. The rotating plate 14 will drive the first conductive block 9 to rotate upward, so that the first conductive block 9 and the second conductive block 13 will no longer be in contact, thereby de-energizing the demister 3. This process will de-energize the demister 3 as long as one sliding door 2 is opened. The demister 3 will only be energized and started when both sliding doors 2 are closed.
[0052] When the two sliding doors 2 are closed, the first magnet 5 on the sliding door 2 will be magnetically connected to the corresponding second magnet 7. At this time, the first sealing ring 6 on the sliding door 2 will be in close contact with the corresponding second sealing ring 10, and the rubber pads at the overlapping positions of the two sliding doors 2 will contact each other to increase the sealing of the overall device. At this time, the rotating plate 14 will rotate due to the pressure of the sliding door 2. The rotating plate 14 will drive the first conductive block 9 to rotate downward, so that the first conductive block 9 contacts the second conductive block 13. At this time, the two first conductive blocks 9 will contact the two second conductive blocks 13 respectively. The top of the rotating plate 14 contacts the bottom of the sliding door 2, so that the plug, the two first conductive blocks 9 and the two second conductive blocks 13 are connected in series, thereby enabling the demister 3 to be powered on and started.
