[0002] In order to make the refrigerator more sealed, a vertical beam is usually set on the refrigerator door to prevent the cold air in the refrigerator compartment from leaking through the gap between the door bodies. However, due to the structure of the vertical beam, when the surface temperature of the vertical beam is lower than the ambient temperature and the humidity of the ambient air is high, condensation is very likely to occur on the surface of the refrigerator vertical beam.

[0003] At present, in order to prevent condensation on the vertical beams, aluminum foil heating wires can be set on the vertical beams, and the heat is transferred to the metal plates of the vertical beams through the aluminum foil heating wires for decondensation. However, in this process, the heat is heated by the aluminum foil, and the heat is transferred to the polyvinyl chloride insulated cable (PVC) wire by the heating wire, and then the heat is transferred to the metal plates of the vertical beams by the PVC wire, resulting in low thermal efficiency and high power consumption.

[0046] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0047] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0048] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0049] In order to make the refrigerator more sealed, a vertical beam is usually set on the refrigerator door to prevent the cold air in the refrigerator compartment from leaking through the gap between the door bodies. However, due to the structure of the vertical beam, when the surface temperature of the vertical beam is lower than the ambient temperature and the humidity of the ambient air is high, condensation is very likely to occur on the surface of the refrigerator vertical beam.

[0050] At present, in order to remove the dew on the vertical beams on the refrigerator door, heat is heated by aluminum foil, and the heat is transferred to the PVC wire by the heating wire, and then the heat is transferred to the metal plate by the PVC wire.

[0051] The above method is used to remove the exposure of vertical beams, but there are the following problems:

[0052] Problem 1: Heat transfer is slow, resulting in low thermal efficiency.

[0053] Question 2: For certain areas of the vertical beam, such as the middle area of ​​the metal plate, there is less condensation and does not require too much heat. However, the above method can only heat the entire vertical beam, which is more power-consuming and causes abnormal reactions in the plastic parts around the heating wire, such as odor, yellowing or deformation.

[0054] Question 3: In the above method, it is necessary to install an additional temperature sensor and increase the control circuit of the temperature sensor, which makes the vertical beam structure more complicated. In order to improve the aesthetics and integrity of the refrigerator, a flat-embedded refrigerator is currently used. The temperature sensor is placed in the hinge box or the press compartment, which is easily blocked by the cabinet doors or walls in the user's home, affecting the judgment of the ambient temperature value.

[0055] Therefore, the present application provides a refrigerator, in which a vertical beam assembly is arranged on the metal plate of the refrigerator door body, and the vertical beam assembly includes a thin film electric heating element attached to the metal plate, and the electric heating wire on the thin film electric heating element is configured into multiple sections, and the electric heating wires of each section are connected in parallel, so that the electric heating wire of the section with a temperature higher than a preset temperature is interrupted by the temperature sensing module on each section, that is, the operation of the electric heating wire in the section is interrupted, and the operation of other electric heating wires is not affected, thereby realizing segmented temperature control of the electric heating wire, so as to achieve energy saving and power saving, and higher thermal efficiency.

[0056] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0057] Figure 1 A schematic diagram of the overall structure of a refrigerator provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, Figure 11 is a front view of a refrigerator 10, which includes:

[0058] Box body 101, storage room 102, door body 103, vertical beam assembly 105 arranged on door body 103. In order to better illustrate the vertical beam assembly 105, Figure 2 This is a schematic diagram of another perspective of the refrigerator 10 according to the embodiment of the present application. Figure 2 Shown in FIG. 1 is the front side of the metal plate 104 of the vertical beam assembly 105 .

[0059] The storage chamber 102 is arranged in the box body 101, the door body 103 is used to open or close the storage chamber 102, and the vertical beam assembly 105 is used to seal the gap between the door body 103 and the box body 101 after the door body 103 is closed.

[0060] Exemplarily, the storage room 102 may be a refrigerator, or the storage room 101 may include a refrigerator and a freezer, etc., which is not limited in the present application. Figure 1 and Figure 2 The storage room in the figure is only an example. It should be understood that in order to better illustrate the vertical beam assembly 105, Figure 1 and Figure 2 The other door body is not shown.

[0061] by Figure 1 and Figure 2 Taking the double door as an example, when both doors are closed, the first side of the door body 103 is butted against one side of the other door body (not shown in the figure). In order to more clearly show the position of the vertical beam assembly 105, Figure 3 Schematic diagram of a door body 103 according to an embodiment of the present application. Figure 3 What is shown is the inner side of the door body 103 facing the storage room 102, wherein the vertical beam assembly 105 is rotatably installed on the first side of the door body 103 as a whole, and when the door body 103 and another door body are closed, they are in conflict with the other door body to close the gap between the door body 103 and the other door body and the box body 101.

[0062] In one possible implementation, Figure 4 A schematic diagram of an exploded structure of a vertical beam assembly 105 provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the vertical beam assembly 105 also includes: a thin film electric heating element 51, a vertical partition seat 52, a vertical partition cover plate 53, insulation cotton 54 and foam 55. The vertical partition seat 52 can be rotatably installed on the door body 103. Specifically, the vertical partition seat 52 can be rotatably installed on the first side of the door body 103.

[0063] The vertical partition cover plate 53 is buckled on the vertical partition seat 52, and defines a storage space with the vertical partition seat 52. The storage space is used to set the heat insulation cotton 54 and the foam 55 to improve the thermal insulation performance of the vertical beam assembly 105. The metal plate 104 covers the vertical partition cover plate 53, and the thin film electric heating element 51 is attached to the side of the metal plate 104 facing the vertical partition cover plate 53 (i.e., the inner side).

[0064] Figure 5 It is a schematic diagram of a packaged vertical beam assembly 105 according to an embodiment of the present application.

[0065] Figure 6 A schematic diagram of the structure of a thin film electric heating element 51 provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the thin film electric heating element 51 includes: a polyethylene terephthalate (PET) film 510, an electric heating wire 511 printed on the PET film 510, and a plurality of temperature sensing modules.

[0066] The electric heating wire 511 is used to provide heat to the vertical beam assembly 105 during heating to achieve dew removal. For example, the electric heating wire 511 can generally reach the target temperature in more than ten seconds, while the aluminum foil heating needs 50-80 seconds to reach the target temperature, with high thermal efficiency and fast temperature rise.

[0067] In a possible implementation, the electric heating wire 511 is configured into multiple sections, and multiple temperature sensing modules are respectively disposed on the electric heating wire corresponding to the multiple sections, so that the temperature of the section in which the temperature sensing module is located can be detected.

[0068] For example, in order to clearly show the positions of the electric heating wires 511 of multiple sections on the metal plate 104, Figure 7 Schematic diagram of a thin film electric heating element 51 and a metal plate 104 according to an embodiment of the present application. Figure 7 The metal plate 104 ( Figure 7 The shape of the metal plate 104 is only an example). Figure 5 As shown, the multiple segments may include a first segment, a second segment and a third segment, wherein the electric heating wire of the first segment is arranged in the first area of ​​the metal plate 104, the electric heating wire of the third segment is arranged in the second area of ​​the metal plate 104, and the electric heating wire of the second segment is arranged in the middle area of ​​the metal plate 104.

[0069] Correspondingly, the plurality of temperature sensing modules include a temperature sensing module 512 disposed on the electric heating wire of the first section, a temperature sensing module 513 disposed on the electric heating wire of the second section, and a temperature sensing module 514 disposed on the electric heating wire of the third section.

[0070] It should be understood that the first area, the second area and the middle area are only used to describe the locations of the multiple segments. Figure 7 The sizes of the various regions shown in are only examples.

[0071] In one possible implementation, the electric heating wires of multiple sections are connected in parallel. For any temperature sensing module, the temperature sensing module is used to detect the first temperature of the target section where the temperature sensing module is located. When the first temperature reaches the preset temperature corresponding to the target section, the electric heating wire of the target section is interrupted.

[0072] In a possible implementation, the temperature sensing module may be a thermistor (Positive Temperature Coefficient, PTC), also known as a positive temperature coefficient thermistor, whose resistance value increases with increasing temperature.

[0073] Taking the first section as an example, the temperature sensing module 512 is used to detect the first temperature of the first section of the metal plate 104. When the first temperature reaches the preset temperature corresponding to the first section, the electric heating wire of the first section is interrupted so that the electric heating wire of the first section stops working.

[0074] For example, the preset temperature of the first section is 35°C (degrees Celsius). When the first temperature reaches 35°C, its resistance value increases sharply, thereby disconnecting the circuit and stopping the electric heating wire of the first section from working.

[0075] Due to frequent door opening and closing by users, the vertical beam assembly 105 is prone to poor sealing and cold leakage, resulting in more condensation at the upper and lower ends of the vertical beam assembly 105, and less condensation in the middle. The temperature of different areas can be controlled in the following ways:

[0076] In one possible implementation, different preset temperatures can be set for different sections. Specifically, the preset temperatures of the sections corresponding to the two end regions of the metal plate 104 are greater than the preset temperatures of the sections corresponding to the middle region of the metal plate 104, that is, the preset temperatures of the first section and the third section are both greater than the preset temperatures of the second section, so that when the electric heating wire 511 is heated for the same length of time, the first temperature of the second section will reach the preset temperature first, causing the electric heating wire of the second section to be interrupted. At this time, the electric heating wires of the first section and the third section are still working, thereby achieving energy saving.

[0077] The preset temperature of the first section and the preset temperature of the third section may be the same, for example, the preset temperature of the first section and the preset temperature of the third section may be set to 40°C, and the preset temperature of the second section may be set to 35°C.

[0078] Exemplarily, the heating power of the electric heating wire 511 is 12W, and the electric heating wires of the first section, the second section and the third section are all 4W connected in parallel. When the electric heating wire 511 is heated for the same time, the first temperature of the second section will first reach the preset temperature of the section, so that the electric heating wire of the second section will be disconnected, and only the first section and the third section will continue to work, thereby achieving energy saving.

[0079] Exemplarily, Table 1 shows the ratio of heating power to power-on time of the electric heating wire 511 after power-on at different temperatures and different humidity levels.

[0080] Table 1

[0081]

[0082] Taking the humidity of 30%≤R<40% and the temperature Te<21℃ as an example, after working at a heating power of 12W (watts) for 7% of a working cycle, it works at a heating power of 8W for 2% of a working cycle. For example, the working cycle is 60 seconds, and the electric heating wire 511 works at a heating power of 12W for 4.2 seconds, and then works at a heating power of 8W for 1.2 seconds. Since the humidity is relatively low and the ambient temperature is relatively low, the heating time of the electric heating wire 511 is relatively short. Therefore, in this working cycle, the electric heating wire 511 may not work for the remaining time.

[0083] As can be seen from Table 1, energy saving can be achieved by removing dew from the vertical beams of the refrigerator through the thin film electric heating element 51.

[0084] In one possible implementation, Figure 6 As shown, the electric heating wire 511 is configured to bend and extend along the length direction of the metal plate 104, wherein the extension length of the electric heating wire in the sections corresponding to the two end regions of the metal plate 104 is smaller than the extension length of the electric heating wire in the sections corresponding to the middle region of the metal plate 104.

[0085] That is to say, the extended length of the electric heating wire in the first section and the third section is shorter than the extended length of the electric heating wire in the second section. Since there is more condensation at both ends of the vertical beam assembly 105 and relatively less condensation in the middle area, less heat is required in the middle area. By setting the extended length of the electric heating wire in the second section to be longer than the extended length of the electric heating wire in the first section and the third section, temperature control of different areas of the vertical beam assembly 105 can be achieved.

[0086] In one possible implementation, when the electric heating wire 511 is bent and extended along the length direction of the metal plate 104, the arrangement density of the electric heating wire in the sections corresponding to the two end regions of the metal plate 104 may be greater than the arrangement density of the electric heating wire in the sections corresponding to the middle region of the metal plate 104.

[0087] That is to say, Figure 6 As shown, the arrangement density of the electric heating wires in the first section and the third section is greater than that in the second section. Since there is more condensation at both ends of the vertical beam assembly 105 and relatively less condensation in the middle area, less heat is required in the middle area. By setting the arrangement density of the electric heating wires in the second section to be smaller than that in the first section and the third section, the temperature control of different areas of the vertical beam assembly 105 can be further accurately achieved.

[0088] In a possible implementation, the electric heating wire 511 can be printed on the PET film 510 by means of conductive paste to form a thin film electric heating element 51 .

[0089] For example, Figure 8 is a schematic diagram of the AA section of the thin film electric heating element 51, as shown in Figure 8 As shown, the electric heating wire 511 is printed on the PET film 510 by means of conductive paste, and the PET film 510 can be attached to the metal plate 104 by means of self-adhesive glue.

[0090] In a possible implementation, the thin film electric heating element 51 further includes: a power conductive lead 515 and a ground conductive lead 516 .

[0091] The power conductive lead 515 is connected to the electric heating wire 511 , and the power conductive lead 515 is used to supply power to the electric heating wire 511 .

[0092] The grounding conductive lead 516 is connected to the electric heating wire 511 , and the electric heating wire 511 is grounded through the grounding conductive lead 516 , so that the thin film electric heating element 51 can work normally.

[0093] In a possible implementation, the circuit corresponding to the thin film electric heating element 51 also includes a first PVC wire and a second PVC wire, one end of the first PVC wire is connected to the power conductive lead 515, one end of the second PVC wire is connected to the ground conductive lead 516, and the other end of the first PVC wire and the other end of the second PVC wire can be connected to other elements in the refrigerator 10 that are connected to the thin film electric heating element 51, such as a controller for controlling the thin film electric heating element 51 to heat.

[0094] In a possible implementation, the electric heating wire 511 is made of conductive silver paste, or can also be made of graphene, which can improve the thermal conductivity of the thin-film electric heating element 51 .

[0095] In the embodiment, the refrigerator 10 includes a box body 101 provided with a storage chamber 102, a door body 103 for opening or closing the storage chamber 102, and a vertical beam assembly 105 arranged on the door body 103. The vertical beam assembly 105 is used to close the gap between the door body 103 and the box body 101 after the door body 103 is closed. The vertical beam assembly 105 includes a metal plate 104 and a thin film electric heating element 51 attached to the metal plate 104. The thin film electric heating element 51 includes a PET film 510 and an electric heating wire 501 printed on the PET film 510. 11 and multiple temperature sensing modules, electric heating wire 511, are used to provide heat for the vertical beam assembly 105 during heating, so as to realize dew removal for the vertical beam assembly 105. Multiple temperature sensing modules are respectively arranged on the electric heating wires corresponding to multiple sections, and the electric heating wires of each section are connected in parallel. For any temperature sensing module, the temperature sensing module is used to detect the first temperature of the target section where it is located. When the first temperature reaches the preset temperature corresponding to the target section, the operation of the electric heating wire of the target section is interrupted without affecting the operation of the electric heating wires of other sections. The present application can realize precise control of the electric heating wires of different sections by integrating a thin-film electric heating element with a temperature sensing module, which can not only achieve energy saving and power saving, but also have higher thermal efficiency.
