Description
Technical Field
[0001] The utility model relates to the technical field of refrigerators, in particular to a refrigerator with a demisting glass door. Background Art
[0002] The temperature inside the freezer is low, and the water vapor in the air easily condenses into tiny water droplets on the glass of the door, causing the door glass to fog up, making it difficult for people to see the items inside the cabinet through the door. Some freezer doors are electrically heated defogger glass doors. This type of door is connected to a power cord, and uses a heating wire to heat the door glass so that the tiny water droplets on the glass evaporate quickly to achieve defogger. The heating wire inside the door is powered by the power cord. The door of the freezer is usually a horizontal sliding door, and people can open the door by pushing the door horizontally. The power cord is generally located in the frame at the top of the cabinet, and the side surface of the inner ring of the frame is provided with a horizontal groove. The edge of the door extends laterally toward the horizontal groove with a power connection part, and the power connection part is connected to the power cord. During the horizontal movement of the door, its power connection part also moves horizontally in the horizontal groove. The door of the freezer generally has two left and right doors arranged side by side, and both doors can be opened horizontally. If the transverse groove is opened on the left side of the cabinet, it will be exposed when the cabinet door is opened to the right. If it is opened on the right side of the cabinet, it will be exposed when the cabinet door is opened to the left. When the transverse groove is exposed, the power connection part and the power cord inside it will be exposed. When the cabinet door is opened, the outside air will be cold and mist will be easily generated. Once the mist enters the transverse groove from the notch of the transverse groove, it will easily wet the power connection part and the power cord. Utility Model Content

[0022] The present invention is further described in detail below in conjunction with specific implementation methods.
[0023] See you in the freezer Figure 1 , including a cabinet 1 with an article access opening 10, and two horizontal sliding cabinet doors 21 and 22 arranged in parallel on the left and right sides are installed at the article access opening 10 of the cabinet 1. The left and right cabinet doors 21 and 22 are usually in a closed state, sealing the article access opening 10 of the cabinet 1. A power supply installation rod 13 is clamped on the top of the cabinet 1. The power supply installation rod 13 serves as the rear edge of the top frame of the cabinet 1, and its front surface 131 is the side surface of the inner ring of the top frame of the cabinet 1. The front surface 131 is provided with a horizontal groove 12, and the left and right ends 121 and 122 of the horizontal groove 12 extend to the left and right sides of the cabinet 1 respectively, such as Figure 2 and Figure 7 See Figure 1 and Figure 3The left cabinet door 21 is an electrically heated defogger glass cabinet door, and a heating wire (not shown in the figure) is arranged inside the left cabinet door 21. A power connection part 212 extends backwards from the rear edge 211 of the left cabinet door 21 toward the transverse groove 12. A power supply module 128 is arranged at the left end of the transverse groove 12, and a power cord 3 extends to the right from the power supply module 128. The power cord 3 is an existing spiral spring cable, which is located in the transverse groove 12 and connected to the power connection part 212 of the left cabinet door 21 to the right, and supplies power to the heating wire inside the left cabinet door 21. The left cabinet door 21 uses the heating wire to heat the glass of the left cabinet door 21 so that the tiny water droplets on the glass evaporate quickly to achieve defogger. This is a prior art and will not be described in detail. People can open the left cabinet door 21 by pushing the left cabinet door 21 to the right to expose the left part 101 of the cabinet access opening 10. During this process, the power connection part 212 of the left cabinet door 21 also moves to the right in the horizontal groove 12, and the power connection part 212 pulls the power cord 3 to the right, causing the power cord 3 to elastically deform and unfold to the right. People can close the left cabinet door 21 by pushing the left cabinet door 21 to the left. During this process, the power connection part 212 of the left cabinet door 21 also moves to the left in the horizontal groove 12, and the power cord 3 is pulled to the right. Figure 8 and Fig. 9 As shown, it automatically retracts and returns to its original position, and will not be entangled or knotted due to the reciprocating motion of the power connection portion 212. Figure 6 and Figure 8 When the left cabinet door 21 is closed, people can push the right cabinet door 22 to the left to open the right cabinet door 22 to expose the right part 102 of the article access opening 10.
[0024] See Figure 1 , two left and right transverse folding curtains 41 and 42 are installed at the notch 120 of the transverse groove 12. The two folding curtains 41 and 42 have the same structure. Taking the folding curtain 41 on the left as an example, the folding curtain 41 is shown in FIG. Fig.10 and Fig.11 , including 72 baffles 415 arranged transversely, each two adjacent baffles 415 are placed in opposite directions and hinged together, and can rotate relative to each other to move away from each other so that the folding curtain 41 is unfolded, and can also rotate relative to each other to move closer to each other so that the folding curtain 41 is folded. Figure 2 and Fig.11 The top wall and bottom wall of the notch 120 of the transverse groove 12 are respectively provided with upper and lower left and right guide grooves 126 and 127. The hinge shafts 416 and 419 of the left folding curtain 41 are of two types, long and short. The two types of hinge shafts 416 and 419 are arranged at intervals in the transverse direction, and the upper and lower ends of the long hinge shaft 416 are respectively inserted into the upper and lower guide grooves 126 and 127. Fig.11Taking the three adjacent baffles 411, 412, and 413 in the embodiment as an example, the left end 4111 of the first baffle 411 is forward and the right end 4112 is backward, the left end 4121 of the second baffle 412 is backward and the right end 4122 is forward, the left end 4131 of the third baffle 413 is forward and the right end 4132 is backward, the right end 4112 of the first baffle 411 is hinged to the left end 4121 of the second baffle 412, and the hinge axis therebetween is a short hinge axis 419, the right end 4122 of the second baffle 412 is hinged to the left end 4131 of the third baffle 413, and the hinge axis therebetween is a long hinge axis 416, and the upper and lower ends of the long hinge axis 416 are respectively inserted into the upper and lower guide grooves 126 (see Figure 2 )、127(see Figure 2 ) Figure 2 , Figure 5 and Figure 7 The left and right ends 121 and 122 of the transverse groove 12 are provided with left and right cabinet hinges 123 and 124 respectively on the groove wall, and the rear edge 211 of the left cabinet door 21 is provided with left and right cabinet door hinges 213 and 214 respectively on the left and right sides of the power connection part 212. The left end of the leftmost stopper 415 serves as the left end 411 of the left folding curtain 41, and is hinged to the left cabinet hinge 123, so as to hinge the groove wall of the left end 121 of the transverse groove 12. The right end of the rightmost stopper 415 serves as the right end 412 of the left folding curtain 41, and is hinged to the left cabinet door hinge 213, so as to hinge the rear edge 211 of the left cabinet door 21. The folding curtain 42 on the right has the same structure as the folding curtain 41 on the left, which will not be described in detail here. Its left end 421 is hinged to the cabinet door hinge part 214 on the right, thereby hinged to the rear edge 211 of the left cabinet door 21, and its right end 422 is hinged to the cabinet body hinge part 124 on the right, thereby hinged to the groove wall of the right end 122 of the transverse groove 12.
[0025] See Figure 1 , Figure 2 and Figure 3 When the left cabinet door 21 is opened to the right, the right end 412 of the folding curtain 41 on the left (see Figure 5 ) is hinged to the rear edge 211 of the left cabinet door 21, the left cabinet door 21 can drive the right end of the left folding curtain 41 to move to the right. During this process, each two adjacent baffles 415 of the folding curtain 41 move away from each other and the long hinge shaft 416 of the folding curtain 41 moves along the guide grooves 126 and 127. In this way, the left cabinet door 21 drives the left folding curtain 41 to move to the right. Figure 4 As shown in FIG. 1 , the unfolded left folding curtain 41 blocks the left side of the notch 120 of the transverse groove 12; at the same time, due to the left end 421 of the right folding curtain 42 (see FIG. 1 ), the left end 421 of the right folding curtain 42 is blocked by the notch 120 of the transverse groove 12. Figure 5) The rear edge 211 of the left cabinet door 21 is hinged, and the left cabinet door 21 can drive the left end 421 of the right folding curtain 42 to move to the right, that is, drive the right folding curtain 42 to be folded to the right, so the right folding curtain 42 does not affect the movement of the left cabinet door 21, and the right folding curtain 42 after being folded blocks the right side of the notch 120 of the transverse groove 12. When the left cabinet door 21 is opened to the right, the left part 101 of the cabinet access opening 10 is exposed, and the outside air is easy to generate fog when it encounters cold at the left part 101 of the cabinet access opening 10. Since the left folding curtain 41 blocks the left side of the notch 120 of the transverse groove 12, it is not easy for fog to enter the transverse groove 12 from the left side of the notch 120 of the transverse groove 12. Since the left cabinet door 21 blocks the right side of the article access opening 10, it is not easy for fog to float to the right across the left cabinet door 21 to the right side of the notch 120 of the transverse groove 12. Even if a small amount of mist floats over the left cabinet door 21 to the right side of the slot 120 of the transverse slot 12, the mist is not easy to enter the transverse slot 12 from the right side of the slot 120 of the transverse slot 12 because the right folding curtain 42 blocks the right side of the slot 120 of the transverse slot 12. It can be seen that the external mist is not easy to enter the transverse slot 12 from the slot 120 of the transverse slot 12, and it is not easy to wet the power connection part 212 and the power cord 3 in the transverse slot 12. Figure 6 , Figure 8 and Fig. 9 When the left cabinet door 21 is closed to the left, the left cabinet door 21 drives the folding curtain 41 on the left. Fig.12 As shown, the folding curtain 41 on the left is folded to the left, and the folding curtain 41 on the right is unfolded to the right. The folded curtain 41 on the left and the closed left cabinet door 21 together block the left side of the slot 120 of the transverse groove 12, and the unfolded folding curtain 42 on the right continues to block the right side of the slot 120 of the transverse groove 12. When the right cabinet door 22 is opened to the left to expose the right part 102 of the article access opening 10, the outside air is easy to generate mist when it encounters cold at the right part 102 of the article access opening 10, but because the folding curtain 42 on the right blocks the right side of the slot 120 of the transverse groove 12, the mist is not easy to enter the transverse groove 12 from the right side of the slot 120 of the transverse groove 12, and because the folding curtain 41 on the left and the closed left cabinet door 21 together block the left side of the slot 120 of the transverse groove 12, the mist is not easy to enter the transverse groove 12 from the left side of the slot 120 of the transverse groove 12, so the mist is not easy to wet the power connection part 212 and the power line 3 in the transverse groove 12.
[0026] See Figure 1 , Figure 2 and Figure 3In this embodiment, the upper left cabinet door 21 is an electrically heated defogger glass cabinet door, and the lower right cabinet door 22 is an ordinary cabinet door. In other embodiments, the upper left cabinet door 21 can be changed to an ordinary cabinet door, and the lower right cabinet door 22 can be an electrically heated defogger glass cabinet door, and the positions of the power supply mounting rod 13 and the transverse groove 12 can be adjusted accordingly, so that the transverse groove 12 can correspond to the rear edge of the right cabinet door 22, and the power line 3 in the transverse groove 12 supplies power to the right cabinet door 22, which will not be repeated here.
[0027] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
