Abstract
Description
Technical Field
[0001] This application relates to the field of household appliances, and in particular to a refrigeration device. Background Technology
[0002] After a period of use, frost will form on the surface of the evaporator fins of a refrigerator. The longer the refrigerator runs, the thicker the frost will accumulate, which will affect the heat transfer rate. Therefore, it is necessary to remove the frost to solve the heat transfer problem.
[0003] In existing technologies, steel pipe heaters are typically used to defrost the evaporator. After the cumulative compressor operating time reaches a certain value, the steel pipe heater begins to heat up, melting the frost layer adhering to the evaporator fins. When the refrigerator is in cooling mode, the temperature inside the evaporator can reach -40°C, and when the refrigerator is in defrosting mode, the temperature inside the evaporator can reach 100°C. When the refrigerator is constantly in a state of alternating cooling and defrosting, the wires connected to the steel pipe heater are subjected to alternating hot and cold conditions, causing the wires to age rapidly. This not only shortens the refrigerator's lifespan but also poses certain risks. Utility Model Content

The heating device is electrically connected to the wire. When the heating device is energized, it can generate heat to melt the frost on the surface of the evaporator. The sleeve is fitted over at least a portion of the outer surface of the wire.
[0006] In some embodiments, the sleeve is a glass fiber sleeve.

[0009] The sleeve is fitted over at least a portion of the outer surface of the first conductor; and / or the sleeve is fitted over at least a portion of the outer surface of the second conductor.
[0010] In some embodiments, the first conductor includes a first line, a first fuse, and a second line connected in sequence, wherein the outer surfaces of both the first line and the second line are fitted with the sleeve; and / or,
[0011] The second conductor includes a third line, a second fuse, and a fourth line connected in sequence, and the outer surfaces of the third line and the fourth line are covered with the sleeve.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0031] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0032] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0033] Please see Figures 1 to 4 This application provides a refrigeration device 100, including an evaporation chamber. The evaporation chamber is provided with an evaporator 30, a heating device 40, a wire, and a sleeve 60. The heating device 40 is electrically connected to the wire. When the heating device 40 is energized, it can generate heat to melt the frost on the surface of the evaporator 30. The sleeve 60 is sleeved on the outer surface of at least a portion of the wire.
[0034] For example, the refrigeration equipment 100 can be a refrigerator, freezer, cold drink machine, refrigerated wine cabinet, freezer box, ice cream machine, ice maker, etc.
[0035] The refrigeration device 100 provided in this application embodiment can protect the wire by providing a sleeve 60 on the outer surface of the wire connected to the heating device 40. Since the sleeve 60 has a certain heat insulation capacity, it can slow down the heat transfer rate between the external environment and the wire, so that the temperature change of the wire in the refrigeration state and the defrosting state is not large, thereby delaying the aging rate of the wire and extending the service life of the refrigeration device 100.
[0036] For example, the sleeve 60 is a glass fiber sleeve.
[0037] It should be noted that the fiberglass sheath has good heat and cold resistance. The working temperature of the fiberglass sheath is -50℃ to 200℃, which can adapt to various temperature environments. It also has a slow aging rate and can provide long-term and stable protection for the conductors. In addition, the fiberglass sheath has good thermal insulation effect. When the refrigeration equipment 100 alternates between refrigeration and defrosting modes, the temperature change of the conductors is small due to the isolation effect of the fiberglass sheath, which can slow down the aging rate of the conductors and thus extend the service life of the refrigeration equipment 100.
[0038] Compared to fiberglass conduits, plastic conduits (such as PVC conduits) have poor heat and cold resistance. Plastic conduits age faster in environments with alternating hot and cold temperatures, thus failing to protect the conductors.
[0039] In addition to its heat and cold resistance, fiberglass sleeving also boasts excellent insulation, high mechanical strength, corrosion resistance, and environmental safety. Its extremely high insulation performance effectively prevents current leakage, ensuring electrical safety. Furthermore, its good corrosion resistance makes it highly resistant to acids, alkalis, salts, and other chemicals, making it suitable for various harsh environments. Finally, the use of non-toxic and harmless environmentally friendly materials effectively protects the health of users.
[0040] Please see Figure 1 The heating device 40 includes a heating tube and a heating wire disposed inside the heating tube, and the heating wire is electrically connected to the wire.
[0041] For example, the heating element is made of metal, such as stainless steel.
[0042] Please see Figure 3 The wires include a first wire 51 and a second wire 52, which are respectively disposed at both ends of the heating tube. The two ends of the heating wire in the heating tube are respectively connected to the first wire 51 and the second wire 52.
[0043] Please see Figure 3 For example, the sleeve 60 is fitted over at least a portion of the outer surface of the first conductor 51.
[0044] Please see Figure 3 For example, the sleeve 60 is fitted over at least a portion of the outer surface of the second conductor 52.
[0045] Please see Figure 3The first conductor 51 includes a first line, a first fuse 71 and a second line connected in sequence, and the outer surfaces of the first line and the second line are both covered with the sleeve 60.
[0046] It is understandable that by connecting the first circuit, the first fuse 71, and the second circuit in series, when the temperature of the first circuit and / or the second circuit reaches the temperature threshold of the first fuse 71, the first fuse 71 will cut off the circuit, thereby preventing accidents such as fires from occurring.
[0047] Please see Figure 3 The second conductor 52 includes a third line, a second fuse 72 and a fourth line connected in sequence, and the outer surfaces of the third line and the fourth line are covered with the sleeve 60.
[0048] Understandably, by connecting the third circuit, the second fuse 72, and the fourth circuit in series, when the temperature of the third circuit and / or the fourth circuit reaches the temperature threshold of the second fuse 72, the second fuse 72 will cut off the circuit, thereby preventing accidents such as fires from occurring.
[0049] Please see Figures 1 to 4 The evaporation chamber is also equipped with a support assembly, and the evaporator 30 and the heating device 40 are both connected to the support assembly.
[0050] Please see Figure 3 The support assembly includes a first support 81 and a second support 82 spaced apart. The opposite sides of the evaporator 30 are respectively connected to the first support 81 and the second support 82, and the opposite sides of the heating device 40 are respectively connected to the first support 81 and the second support 82.
[0051] Please see Figure 3 The evaporator 30 includes an evaporator tube 31 and a plurality of fins 32. The plurality of fins 32 are all sleeved on the outer surface of the evaporator tube 31 and are all connected to the evaporator tube 31. The evaporator tube 31 passes through the first support 81 and the second support 82 and is connected to the first support 81 and the second support 82. The plurality of fins 32 are distributed on the evaporator tube 31 in the area between the first support 81 and the second support 82.
[0052] For example, the evaporator tube 31 contains a refrigerant. In some embodiments, the refrigerant is a halogenated hydrocarbon, such as a chlorofluorocarbon.
[0053] Please see Figure 1 and Figure 2The refrigeration equipment 100 includes a cabinet 20 and a partition (not shown). The partition is disposed inside the cabinet 20 and divides the inner cavity of the cabinet 20 into an evaporation chamber and a storage chamber.
[0054] For example, the partition is an air duct baffle.
[0055] For example, the storage compartment is a refrigerator compartment or a freezer compartment.
[0056] Please see Figure 1 and Figure 2 Both the first bracket 81 and the second bracket 82 are connected to the inner box 20.
[0057] For example, both the first bracket 81 and the second bracket 82 can be connected to the box liner 20 by screws.
[0058] Please see Figure 4 At the same time, combined Figure 1 and Figure 2 The bottom of the evaporation chamber may also be provided with a water receiving tray 90, the support assembly is provided on the water receiving tray 90, and the water receiving tray 90 is provided with a drain outlet 91.
[0059] Understandably, during the operation of the evaporator 30, water vapor in the air will condense into water when it encounters the low-temperature surface of the evaporator 30. This water can be collected in the water collection pan 90 and discharged through the drain port 91 of the water collection pan 90.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
