Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a water pipe with a defrosting function and a refrigerator using the water pipe. Background Art

[0002] Frost can have a number of effects on a refrigerator. First, it reduces the efficiency of the refrigerator, leading to increased energy consumption, as the refrigerator needs to spend more energy to maintain the temperature. Second, a large amount of frost will take up space inside the refrigerator, reducing the available storage space. In addition, too much frost may also affect the quality of refrigerated food, as frost may cause the food to dry out or become damp. Therefore, regularly removing frost from the refrigerator is key to maintaining refrigerator efficiency and food freshness.

[0003] When the refrigerator is frosted, it is usually cleaned manually. First, take out the food in the refrigerator and temporarily put it somewhere else. Then, turn off the power of the refrigerator, open the refrigerator door, let the frost melt into water, and absorb the water with a clean cloth or sponge. You can use warm water to gently wipe the frost to speed up the defrosting process. Finally, after the refrigerator is completely dry, reload the food and turn on the refrigerator power. This defrosting operation is troublesome and time-consuming.

[0004] In the patent "A Refrigerator Defrosting Electric Heating Tube" (publication number CN207365541U, hereinafter referred to as prior art 1), a heating tube that can control the temperature for defrosting is disclosed.

In prior art 1, a heat shrink tube is used for heat shrink process sealing, so that the refrigerator defrosting electric heating tube has reliable sealing, easy production, strong practicality, high quality reliability of the production process, and low production cost. Specifically, the electric heating pipe fittings include a stainless steel pipe, a heating wire, a lead rod and magnesium powder; the heating wire is arranged in the stainless steel pipe, the lead rod is led out from one end or both ends of the heating wire, and is fixedly welded with the wire group by butt welding or argon welding, and magnesium powder is filled between the stainless steel pipe and the heating wire. The electric heating pipe fittings are U-shaped, M-shaped or double U-shaped, and the outer wall is provided with protrusions, which are distributed in a threaded shape around the circumference of the outer wall of the electric heating pipe fittings or in a corrugated shape along the axis of the outer wall of the electric heating pipe fittings, and are used to expand the heat exchange surface area of ​​the wall of the refrigerator defrosting pipe. In the prior art 1, an additional electric heating tube is used for defrosting, which increases electrical appliances and generates other energy consumption; and external energy is used for heating and defrosting, which is not conducive to energy utilization and conservation.

[0025] Example 1

[0026] See also Figure 1, the embodiment of the utility model provides a water pipe with a defrost function, including a defrost water pipe 151 and a heating pipe 153. The defrost water pipe 151 is made of high-quality materials that are resistant to low temperatures and frost cracks to meet the use requirements in various cold environments. The heating pipe 153 is evenly wound around the outside of the defrost water pipe 151. The defrost water pipe 151 is formed by a pipe extending upward in a spiral shape; one end of the heating pipe 153 is wound around the outer surface of the defrost water pipe 151; the inner wall surface of the defrost water pipe 151 is made of a smooth material to reduce the resistance of water flow when passing through and improve the defrost efficiency. At the same time, the spiral design of the defrost water pipe 151 not only increases the contact area of ​​the water flow, but also makes the water flow produce a rotating effect during the flow, further promoting the dissolution of frost.

[0027] See also Figure 1 , the other end of the heating pipe 153 is connected to a heat source. Through the heat transfer from the heat source, the heating pipe 153 can heat up quickly and transfer the heat to the defrost water pipe 151, so that the surface temperature of the water pipe rises, thereby accelerating the melting of frost. At the same time, the connection between the defrost water pipe 151 and the heating pipe 153 is sealed to prevent moisture from penetrating, thereby ensuring the safe and stable operation of the equipment. During the defrosting process, the liquid flow in the defrost water pipe 151 circulates continuously, and the liquid after the frost melts flows out along the outer surface of the defrost water pipe 151 to avoid the formation of water accumulation on the equipment. Or after the inside of the defrost water pipe 151 is frosted, the defrost water pipe 151 is blocked, and the defrost water pipe 151 is heated by the heating pipe 153 so that the inside of the defrost water pipe can circulate after defrosting.

[0028] See also Figure 1 The heating pipe 153 is provided with an inlet end 154 and an outlet end 155; the inlet end 154 and the outlet end 155 are provided with a first connecting valve 156 and a second connecting valve 157 respectively. By opening or closing the first connecting valve 156 and the second connecting valve 157, the heating pipe 153 is connected or closed with the heat source, so that the heating pipe 153 is connected when needed and closed when not needed. The heating pipe 153 is wound around the outer surface of the defrosting water pipe 151. Furthermore, the first connecting valve and the second connecting valve are opened or closed at the same time; by opening or closing the first connecting valve and the second connecting valve at the same time, the heating pipe 153 is connected or closed with the heat source.

[0029] The heating tube 153 is extended from the top to the bottom of the defrost water pipe 151 . A water receiving box 17 is provided at the bottom of the defrost water pipe 151 , and both sides of the water receiving box 17 cover the positions of both sides of the defrost water pipe 151 .

[0030] See also Figure 1 Furthermore, a drainage pipe 18 is provided at the bottom of the water receiving box 17 so as to smoothly discharge the melted frost liquid. A splash-proof net can be provided at the outlet of the drainage pipe 18 to prevent water from splashing out and causing damage to components. In a specific embodiment, the water pipe with defrosting function can be widely used in various refrigeration equipment, such as freezers, refrigerators, etc. By using a part of the condenser tube of the condenser 13 or the evaporator 14 as the defrosting water pipe 151, and arranging a heating pipe 153 on this part of the defrosting water pipe 151; the frost can be melted quickly, and the refrigeration efficiency and service life of the equipment can be improved. In addition, the water pipe with defrosting function can also be used in conjunction with other components to further improve the defrosting effect. For example, a heat dissipation hole 19 can be provided on the outside of the defrosting water pipe 151, and the heat emitted by the heat dissipation hole 19 accelerates the melting process of the frost. At the same time, a thermal insulation layer can also be provided on the outer surface of the defrosting water pipe 151 to reduce heat loss and improve defrosting efficiency.

[0031] Furthermore, in order to ensure the long-term stable operation of the water pipe with the defrosting function, it is necessary to regularly perform maintenance and upkeep. For example, it is necessary to regularly check the working state of the heating pipe 153 to ensure that it is heating normally; at the same time, it is also necessary to regularly clean the dirt and impurities inside the defrosting water pipe 151. The water pipe has the advantages of simple structure, convenient installation, safety and reliability, etc., and can be widely used in various refrigeration equipment to improve the refrigeration efficiency and service life of the equipment.

[0032] Example 2

[0033] See also Figure 1The embodiment of the utility model provides a refrigerator, comprising a box body 1, an inner tank 11, a compressor 12, a condenser 13 and an evaporator 14; and also comprising the defrosting water pipe 151 and the heating pipe 153 as described above; a cavity is provided between the box body 1 and the inner tank 11; the evaporator 14, the compressor 12 and the condenser 13 are all provided in the cavity at the back of the inner tank 11; the condenser 13, the compressor 12 and the evaporator 14 are connected through a condensing pipe 15; part of the condensing pipe 15 between the evaporator 14 and the condenser 13 is set as a defrosting water pipe 151; the condensing pipe 15 between the condenser 13 and the compressor 12 is a heat dissipation pipe 152; and a plurality of heat dissipation fins 21 are provided on the heat dissipation pipe 152. The inlet end 154 and the outlet end 155 of the heating pipe 153 are respectively connected to the two ends of the heat dissipation pipe 152. Generally, the high-temperature refrigerant flows from one end of the heat dissipation pipe 52 to the other end, and the refrigerant dissipates heat during the time of circulation in the heat dissipation pipe 152. The inlet end 154 of the heating pipe 153 is the high-heat end of the heat dissipation pipe 152; the outlet end 155 of the heating pipe 153 is the low-heat end of the heat dissipation pipe 152. When the first connecting valve 156 and the second connecting valve 157 are opened, the heating pipe 153 is connected with the heat dissipation pipe 152, and the high-heat refrigerant flows into the heating pipe 153, and the defrosting water pipe 151 is heated and defrosted. In the defrosting process, the refrigerant gradually cools down, which not only has the effect of defrosting, but also has the effect of heat dissipation. After the refrigerant passes through the heating pipe 153, it flows into the low-heat end of the heat dissipation pipe 152 from the outlet end 154 and continues to circulate, thereby completing defrosting and heat dissipation. This arrangement saves energy consumption and improves energy utilization efficiency. By introducing the high-heat refrigerant into the heating pipe 153 for defrosting operation, not only the defrosting water pipe 151 is quickly heated, but also the heat of the refrigerant is fully utilized, avoiding energy waste. At the same time, the refrigerant gradually cools down while flowing in the heating tube 153, further achieving the heat dissipation effect and improving the performance of the entire refrigeration system.

[0034] The first connecting valve 156 and the second connecting valve 157 play a key role in connecting and closing the circulation of refrigerant in the system. Considering that they need to be in contact with high-temperature refrigerant and need to ensure good sealing and durability, the valves need to be able to withstand the high temperature of the refrigerant to ensure that they can work normally without damage in a high-temperature environment. Secondly, the valve should have good sealing performance to prevent refrigerant leakage and ensure the stability and safety of the system. In addition, the valve should also have a long service life and stable performance to meet the needs of long-term operation of refrigeration equipment. Some valve models that perform well in high-temperature environments can be selected, such as high-temperature valves made of stainless steel or valves dedicated to refrigeration systems.

[0035] See also Figure 1 and Figure 2 In this embodiment, a refrigerator is further provided, in which the above-mentioned defrost water pipe 151 is applied. The refrigerator includes conventional components such as a cabinet 1, an inner tank 11, a compressor 12, a condenser 13 and an evaporator 14. In particular, the refrigerator of this embodiment also introduces a water pipe with a defrost function to achieve rapid melting of frost and improve refrigeration efficiency. The refrigerator is provided with a special defrost area in the cavity between the cabinet 1 and the inner tank 11. This defrost area is separated from other parts by heat insulation materials to reduce the influence of heat on the internal temperature of the refrigerator. A part of the evaporator 14 is arranged in the defrost area and is in direct contact with the defrost water pipe 151 to melt the frost more effectively.

[0036] See also Figure 1 The refrigerator of this embodiment is also provided with a heating tube 153 on the condenser tube 15 between the condenser 13 and the compressor 12. Thus, when defrosting is required, the surface temperature of the condenser tube 15 can be increased by controlling the heat conduction state of the heating tube 153, thereby accelerating the melting of frost. This design not only improves the defrosting efficiency, but also enables the refrigerator to continue to operate during the defrosting process, thereby ensuring the continuity of the refrigeration effect.

[0037] See also Figure 2 In order to further improve the refrigeration effect and service life of the refrigerator, this embodiment also adds a number of heat sinks 21 on the condenser 13. These heat sinks 21 can increase the heat dissipation area of ​​the condenser 13 and improve the heat dissipation efficiency, thereby ensuring the stability of the refrigerator when it is running under high load. Figure 1 and Figure 2 By arranging a heating tube 153 on the heat dissipation tube 152, the heating tube 153 helps the heat dissipation of the heat dissipation tube 152, and the defrost water tube 151 can also be heated by the heating tube 153, which not only performs the defrosting work but also helps the heat dissipation to a certain extent.

[0038] The water pipe with defrosting function realizes rapid heating of the defrosting water pipe 151 by setting the heating pipe 153, and effectively prevents the occurrence of frosting of the water pipe. At the same time, the setting of the heating pipe 153 enables the water pipe to be evenly heated during the spiral extension process, thereby improving the defrosting efficiency. In addition, the setting of the water receiving box 17 can effectively collect the melted frost water to prevent it from flowing into other areas and causing damage to components. Moreover, by controlling the connection or closure of the heating pipe 153 and the heat dissipation pipe 152, the defrosting water pipe 151 can be heated according to actual needs, which not only ensures the defrosting effect, but also utilizes the energy of heat dissipation, thereby avoiding unnecessary energy waste. In the application of the refrigerator, by setting part of the condensing pipe 15 as the defrosting water pipe 151, the frost generated by the condenser 13 can be quickly defrosted, thereby ensuring the normal operation of the refrigerator. At the same time, the setting of the heat dissipation pipe 152 and the heat sink 21 enhances the heat dissipation effect of the condenser 13 and improves the refrigeration efficiency of the refrigerator.

[0039] Preferably, the housing 1 is provided with a heat-insulating layer; the compressor 12, condenser 13 and evaporator 14 are all arranged in the cavity between the heat-insulating layer and the inner tank 11. The heat-insulating layer is provided to further improve the heat-insulating effect of the refrigerator and reduce the influence of external heat on the internal temperature of the refrigerator. The heat-insulating layer is usually made of materials with good heat-insulating properties, such as foam plastics, which can effectively isolate the heat exchange between the inside of the refrigerator and the external environment and maintain the stability of the internal temperature of the refrigerator. By arranging core components such as the compressor 12, condenser 13 and evaporator 14 in the cavity between the heat-insulating layer and the inner tank 11, it can be further ensured that the heat generated by these components during operation will not be directly transferred to the inside of the refrigerator, thereby maintaining the constant temperature inside the refrigerator. At the same time, this layout also helps to reduce the noise during the operation of the refrigerator and improve the user experience.

[0040] Preferably, the condenser 13 is disposed at the top of the cavity between the thermal insulation layer and the inner liner 11 and is fixed by the inner wall of the box body 1; the compressor 12 is disposed at one side of the cavity between the thermal insulation layer and the inner liner 11. The defrost water pipe 151 is disposed at the back of the inner liner 11, and the defrost water pipe 151 covers the back of the inner liner 11.

[0041] See also Figure 1Preferably, a drainage hole is provided in the water receiving box 17; the drainage hole is connected to a drainage pipe 18; the drainage pipe 18 passes through the insulation layer and the box body 1 and extends to the outside of the box body 1. The drainage pipe 18 and the insulation layer are sealed. The drainage hole and the drainage pipe 18 in the water receiving box 17 enable the melted frost water to be smoothly discharged from the outside of the refrigerator, thereby avoiding water stains from damaging the inside of the refrigerator. At the same time, the sealed setting of the drainage pipe 18 and the insulation layer effectively prevents heat from being transferred to the insulation layer through the drainage pipe 18, thereby maintaining the insulation effect of the refrigerator.

[0042] See also Figure 2 , the box body 1 at the top of the condenser 13 is provided with a plurality of heat dissipation holes 19; the plurality of heat dissipation holes 19 are arranged at intervals. In order to further optimize the heat dissipation effect of the refrigerator, we set a plurality of heat dissipation holes 19 on the box body 1 at the top of the condenser 13. These heat dissipation holes 19 are arranged at intervals, which effectively increases the heat dissipation area of ​​the condenser 13 and helps the condenser 13 to dissipate heat better. The heat dissipation pipe 152 is provided with a plurality of heat dissipation fins 21; the plurality of heat dissipation fins 21 are arranged at intervals; the plurality of heat dissipation fins 21 are arranged between the two ends of the heating pipe 153 and the heat dissipation pipe 152.

[0043] Example 3

By optimizing the heat dissipation design of the refrigerator, including adding a heat sink 21 and a heat dissipation hole 19, the heat dissipation efficiency of the condenser 13 is improved, and the stability of the refrigerator when running under high load is ensured. This helps to extend the service life of the refrigerator and reduce the failure rate caused by poor heat dissipation. By setting a water pipe with a defrosting function and heating the defrosting water pipe 151 with a heating pipe 153, the frost is quickly melted and the refrigeration efficiency is improved. This design not only avoids the influence of frost on the refrigeration effect of the refrigerator, but also reduces the trouble of manual defrosting by users and improves the convenience of use. The setting of the water receiving box 17 and the drainage pipe 18 enables the melted frost water to be smoothly discharged from the outside of the refrigerator, avoiding water stains from causing damage to the inside of the refrigerator. At the same time, the sealed setting of the drainage pipe 18 and the insulation layer effectively prevents heat from being transferred to the insulation layer through the drainage pipe 18, thereby maintaining the insulation effect of the refrigerator. The water pipe design with defrosting function is adopted, and the defrosting water pipe 151 is heated by the heating pipe 153, so that the frost is melted quickly, thereby avoiding the influence of frost on the refrigeration effect of the refrigerator and improving the refrigeration efficiency. This design not only reduces the trouble of manual defrosting for users, but also improves the convenience of use. In addition, the setting of the water receiving box 17 and the drainage pipe 18 allows the melted frost water to be smoothly discharged from the outside of the refrigerator, effectively preventing water stains from damaging the inside of the refrigerator. At the same time, the sealed setting of the drainage pipe 18 and the insulation layer effectively prevents heat from being transferred to the insulation layer, ensuring the insulation effect of the refrigerator. This design not only facilitates the user's operation, but also reduces the maintenance cost.
