[0003] Most of the existing refrigerators use electric heating defrosting method, which has high defrosting efficiency, saves time and is efficient; however, electric heating defrosting requires the refrigerator to be defrosted regularly. In addition to the high energy consumption factor, the use of high-power heaters also has unsafe factors, and the refrigerator is easily burned due to a failure of the electric heating system.

[0004] The existing patent (publication number: CN205383825U) is a defrosting device for a refrigerator, which stores the heat emitted by the refrigerator condenser through a liquid storage tank, and then leads the heated liquid to the defrost heat exchange coil, thereby exchanging heat with the frost layer of the evaporator for defrosting. The defrosting liquid can be gathered in the liquid collection tank, and then the liquid is returned to the liquid storage tank through a circulating pump and a circulating pipeline, which not only recovers the condensation heat but also improves the condensation efficiency of the condenser.

[0005] In view of the above problems, the existing patent provides a solution. During use, it can only absorb heat when the refrigerator condenser is working, and cannot store heat. When the refrigerator evaporator is defrosted while it is working, it is easy to affect the refrigeration effect of the evaporator and even cause it to be damaged.

[0006] To this end, a heat recycling defrosting refrigerator is proposed. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0031] The heat absorption and air exchange mechanism 2 includes an extension frame 201, a fixed frame 202, a heat conduction plate 203, an installation frame 204, a ventilation fan 205 and a phase-changing wax 206. The extension frame 201 is fixedly connected to one side of the refrigerator body 1, the fixed frame 202 is fixedly connected to one side of the extension frame 201, multiple heat conduction plates 203 are all fixedly connected to the bottom of the fixed frame 202, the installation frame 204 is fixedly connected to one side of the extension frame 201, the ventilation fan 205 is arranged on one side of the installation frame 204, and the phase-changing wax 206 is arranged on one side of the fixed frame 202.

[0032] Specifically, Figure 3 As shown, the heating assembly 4 includes a fixing plate 401 and a heating wire 402 . The fixing plate 401 is fixedly connected to the bottom of the fixing frame 202 , and the heating wire 402 is arranged on one side of the fixing plate 401 .

[0033] Specifically, Figure 5 As shown, the fixing plate 401 is provided with through holes 7 inside, and the number of the through holes 7 is several and evenly distributed.

[0034] Specifically, Figure 1 As shown, a shielding plate 8 is hingedly connected to one side of the extension frame 201 , and a pulling block 9 is fixedly connected to the top of the shielding plate 8 .

[0035] Specifically, Figure 2 As shown, a dustproof plate 10 is threadedly connected to one side of the extension frame 201 .

[0036] When in use, the phase-disguised wax 206 is a substance, and its characteristic is that it can transform between three forms of solid, liquid and gas as the temperature changes. This transformation process is called phase change, and the phase change process is accompanied by the absorption and release of heat. The phase-disguised wax 206 is placed in the fixed frame 202. When the refrigerator is working and generates heat, the heat will be absorbed by the heat conducting plate 203 and transferred to the phase-disguised wax 206. The phase-disguised wax 206 absorbs heat and changes from solid to liquid, and stores heat. The ventilation fan 205 is started to blow the heat on the heat conducting plate 203 out of the extension frame 201. When defrosting is required, the refrigerator condenser is turned off, the temperature in the extension frame 201 will decrease, and the phase-disguised wax 206 will be turned off. 6 will release heat and change from liquid back to solid, and the heat released by the disguised wax 206 will be transferred to the heat conducting plate 203, and the reverse ventilation fan 205 will blow the heat on the heat conducting plate 203 to the refrigerator body 1 to defrost it. The disguised wax 206 is reusable. When the heat of the disguised wax 206 is released but the defrosting work is not completed, the heating wire 402 can be energized to dissipate heat, and the wind from the ventilation fan 205 can blow it through the perforation 7 on the fixed plate 401 to continue the defrosting work. The shielding plate 8 is used in conjunction with the pulling block 9, which can facilitate the user to observe the use of the disguised wax 206. The dustproof plate 10 can prevent external dust from entering the extension frame 201.

[0037] Specifically, Figure 3 As shown, the drainage component 3 includes a groove 301, a water suction pipe 302, a micro water pump 303, a drainage pipe 304 and a storage box 305, the groove 301 is opened on one side of the refrigerator body 1, the water suction pipe 302 is arranged on one side of the refrigerator body 1, the micro water pump 303 is arranged on one side of the extension frame 201, the drainage pipe 304 is arranged on the other side of the micro water pump 303, and the storage box 305 is arranged on one side of the extension frame 201.

[0039] Specifically, Figure 4 As shown, a heat insulation board 11 is provided on one side of the extension frame 201 .

[0040] During the defrosting process of the refrigerator, more water will be generated. The groove 301 can catch the water. By starting the micro water pump 303, the water in the groove 301 can be pumped out from the pumping pipe 302 and discharged into the storage box 305 through the drainage pipe 304 to avoid the defrosting water from leaking out and affecting the use. The fixed column 5 and the limiting plate 6 can limit the storage box 305. When drainage is required, the limiting plate 6 can be rotated to pull out the water tank. The insulation plate 11 can block the heat of the extension frame 201 to avoid affecting the operation of the micro water pump 303.

[0041] By adopting the above technical solution, a problem is solved that an existing defrosting device of a refrigerator can only absorb heat when the refrigerator condenser is working and cannot store heat. When defrosting when the refrigerator evaporator is working, it is easy to affect the refrigeration effect of the evaporator and even cause damage to it.

[0042] Working principle: When the present application is in use, the phase-disguised wax 206 is a substance, and its characteristic is that it can transform between three forms of solid, liquid and gas as the temperature changes. This transformation process is called phase change, and the phase change process is accompanied by the absorption and release of heat. The phase-disguised wax 206 is placed in the fixed frame 202. When the refrigerator is working and generates heat, the heat will be absorbed by the heat-conducting plate 203 and transferred to the phase-disguised wax 206. The phase-disguised wax 206 absorbs heat and changes from solid to liquid, and stores heat. The ventilation fan 205 is started to blow the heat on the heat-conducting plate 203 out of the extension frame 201. When defrosting is required, the refrigerator condenser is turned off, the temperature in the extension frame 201 will drop, and the phase-disguised wax 206 will release heat from the liquid The body turns back into a solid, and the heat released by the disguised wax 206 is transferred to the heat conducting plate 203, and the reverse conversion fan 205 blows the heat on the heat conducting plate 203 to the refrigerator body 1 to defrost it. The disguised wax 206 can be reused. When the heat of the disguised wax 206 is released but the defrosting work is not completed, the heating wire 402 can be energized to dissipate heat, and the wind from the ventilation fan 205 can blow it through the perforation 7 on the fixing plate 401 to continue the defrosting work. During the defrosting process of the refrigerator, more water will be generated, and the groove 301 can catch the water. The micro water pump 303 is started to pump the water in the groove 301 from the pumping pipe 302 and discharge it into the storage box 305 through the drainage pipe 304 to prevent the defrosting water from leaking.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
