[0042] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0043] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0045] At present, when frozen items (including food) in a freezer need to be used, the frozen items need to be taken out of the freezer a long time in advance and placed in the freezer to fully thaw the frozen items. If the frozen items are needed urgently, the thawing time required is long, and insufficient thawing of the items will affect the use of the items.

[0046] In order to accelerate the thawing of frozen items, in the related art, a warm room is set up, and the heat of the condenser is blown into the warm room through the air duct to thaw the food in the warm room. Although the related art can accelerate the thawing of frozen items, it is impossible to judge the thawing status and cannot accurately thaw.

[0047] The present application sets a condenser in the thawing room and uses the condenser temperature to thaw the food. At the same time, a tray for placing the food to be thawed is set as a weight detection tray. The condenser is controlled in real time by a control device according to the weight change of the food to be thawed on the weight detection tray to perform precise thawing.

[0048] Combination Figures 1 to 4 As shown, the embodiment of the present disclosure provides a freezer 10, including a box body 11, a condenser 13, a weight detection tray 15 and a control device. The box body 11 includes a thawing chamber 12; the condenser 13 is arranged in the thawing chamber 12; the weight detection tray 15 is arranged in the thawing chamber 12, and is used to detect the weight of the items to be thawed in the thawing chamber 12; the control device controls the condenser 13 in real time to thaw the items to be thawed according to the weight of the items to be thawed detected by the weight detection tray 15.

[0049] like Figure 1As shown, the weight detection tray 15 opens upward and is used to place the items to be thawed. After the items to be thawed are placed on the weight detection tray 15, the weight detection tray 15 detects that the items to be thawed are placed, and the control device controls the condenser 13 to be turned on to heat the thawing chamber 12 to thaw the items to be thawed. In the disclosed embodiment, the condenser 13 is arranged in the thawing chamber 12, and the temperature of the condenser 13 is used to thaw the food. At the same time, the tray for placing the items to be thawed is arranged as the weight detection tray 15, and the condenser 13 is controlled in real time by the control device to accurately thaw according to the weight change of the items to be thawed on the weight detection tray 15. By arranging the thawing chamber 12 in the box body 11, and arranging the condenser 13 in the thawing chamber 12, the heat generated by the condenser 13 is used to provide heat for the thawing chamber 12, so as to accelerate the thawing of the items to be thawed in the thawing chamber 12, the thawing of the items in the frozen state can be accelerated without the items in the frozen state contacting other substances such as water, thereby improving the practicality of the refrigerator 10. Furthermore, by arranging the thawing chamber 12 in the refrigerator 10, the articles to be thawed can be put into the thawing chamber 12 after being taken out from the refrigeration chamber 113 of the refrigerator 10, thereby improving the convenience of use of the refrigerator 10. At the same time, by arranging the weight sensor or the pressure sensor 112 or the gravity sensor, when the weight detection tray 15 detects the weight, that is, when there are articles to be thawed in the thawing chamber 12, the condenser 13 in the thawing chamber 12 is started to generate heat, the temperature in the thawing chamber 12 is increased, and the articles to be thawed are heated and thawed. The heat generated by the condenser 13 is recycled when the refrigerator 10 is refrigerating, thereby improving the practicality of the thawing chamber 12.

[0050] In some embodiments, the weight detection tray 15 can detect the weight of the items to be thawed in real time, and judge the thawing speed by the mass change speed of the items to be thawed, and control the opening of the temperature compensation member 19 when the thawing speed is less than the first preset speed. The first preset speed can be set according to demand.

[0051] Exemplarily, the first preset speed includes a weight change of 0.1 N per minute. The weight change includes the combined effect of multiple factors such as the melting of ice and the evaporation of water.

[0052] Optionally, the freezer 10 further comprises a bracket, which is used to fix the weight detection tray 15. The bracket is fixedly connected to the inner wall of the thawing chamber 12, or is placed on the bottom wall of the thawing chamber 12.

[0053] In this embodiment, the bracket is fixedly connected to the inner wall of the thawing chamber 12 to make the weight detection tray 15 more stable, preventing the freezer 10 from vibrating and causing the weight detection tray 15 to detect inaccurate weights. At the same time, it is prevented that the items to be thawed move or even fall and damage the inner wall of the thawing chamber 12.

[0054] Optionally, the refrigerator 10 further includes a temperature sensor 18. The temperature sensor 18 is disposed in the thawing compartment 12 and is used to detect the temperature in the thawing compartment 12 in real time.

[0055] like Figure 1 and Figure 3 As shown, the temperature sensor 18 is arranged on the inner wall of the thawing chamber 12 and is located above the weight detection tray 15 for detecting the real-time temperature in the thawing chamber 12 .

[0056] Optionally, the refrigerator 10 further includes a temperature compensation member 19 . The temperature compensation member 19 is disposed in the thawing compartment 12 corresponding to the weight detection tray 15 , and the temperature compensation member 19 is controlled to heat the weight detection tray 15 .

[0057] like Figure 1 , Figure 2 and Figure 4 As shown, a temperature compensation member 19 is provided around the bottom 161 of the weight detection tray 15. The temperature compensation member 19 is used to generate heat. When the condenser 13 is insufficient in heat and cannot thaw the items to be thawed within the required time, the temperature compensation member 19 is activated to heat the bottom 161 of the weight detection tray 15, so that the items to be thawed in the weight detection tray 15 can quickly absorb heat to accelerate thawing.

[0058] In some embodiments, when the weight detection tray 15 detects that the weight of the item to be thawed is greater than a preset weight and the temperature sensor 18 detects that the temperature in the thawing chamber 12 is lower than a first preset temperature, the control device controls the condenser 13 and the temperature compensation member 19 to open simultaneously to speed up thawing.

[0059] In some embodiments, the preset weight includes 5N; and the first preset temperature includes 3°C.

[0060] The preset weight is set to 5N, that is, the mass of the items to be thawed is 0.51kg. Only when the weight of the items to be thawed in the weight detection tray 15 is greater than 0.51kg and the temperature in the thawing chamber 12 is less than 3°C, the temperature compensation member 19 is activated to accelerate thawing. This can reduce the problem of frequent activation of the compressor 14 and the condenser 13 caused by other items not to be thawed (such as a small amount of frost, etc.) in the thawing chamber 12, reduce the energy consumption caused by the setting of the thawing chamber 12, and improve the practicality of the refrigerator 10.

[0061] Specifically, when the weight value detected by the weight detection tray 15 is greater than the preset weight, it is possible that the items to be thawed are located in the thawing chamber 12, or there is water generated during the thawing process of the items to be thawed in the thawing chamber 12, or there is a large amount of frost (the weight of the frost exceeds the preset weight) in the thawing chamber 12 and needs to be defrosted. By setting the preset weight, the demand for thawing the items to be thawed, the demand for evaporating the water generated during the thawing process of the items to be thawed, and the demand for defrosting the thawing chamber 12 are met, thereby improving the practicality of the refrigerator 10.

[0062] It is understandable that the refrigerator 10 provided in the embodiment of the present disclosure also includes other components included in the refrigeration system (such as a compressor and an evaporator, etc.).

[0063] In some embodiments, when the weight detection tray 15 does not detect the items to be thawed, and the temperature sensor 18 detects that the temperature is lower than the first preset temperature, the condenser 13 is controlled to be turned on to heat the thawing chamber 12 until the temperature in the thawing chamber 12 rises to the second preset temperature.

[0064] In the embodiment of the present disclosure, a temperature sensor 18 is provided to detect the temperature in the thawing chamber 12. When the temperature in the thawing chamber 12 is low, the condenser 13 is started to work to maintain the temperature in the thawing chamber 12. When the temperature in the thawing chamber 12 is low, the condenser 13 needs to be turned on for a long time to meet the required thawing temperature when placing the items to be thawed in the thawing chamber 12, thereby reducing the time for thawing in the thawing chamber 12.

[0065] Alternatively, if Figure 1 As shown, the refrigerant pipe of the condenser 13 in the thawing chamber 12 is arranged through the side wall of the thawing chamber 12, and the compressor 14 is arranged in the press chamber below the thawing chamber 12. The refrigerant pipe extends downward from the side wall of the thawing chamber 12 to the press chamber from the side wall to connect the compressor 14 and the condenser 13. It is forbidden to set a through hole in the bottom wall to prevent the water generated by the thawing of the items to be thawed from entering the press chamber through the through hole, causing the components in the press chamber to be corroded.

[0066] Optionally, the condenser 13 is disposed below the weight detection tray 15 ; and the temperature compensation member 19 is disposed between the condenser 13 and the weight detection tray 15 .

[0067] like Figure 1 , Figure 2 and Figure 4As shown, the condenser 13 is arranged below the weight detection tray 15 so that the heat emitted by the condenser 13 first heats the weight detection tray 15. The temperature compensator is arranged between the condenser 13 and the weight detection tray 15 to further heat the weight detection tray 15. The weight detection tray 15 is made of a material with uniform thermal conductivity and can evenly transfer heat to the items to be thawed, so that the items are heated evenly and will not cause local overheating and deterioration.

[0068] Optionally, the temperature compensation element 19 includes one or more of a heating wire, a heating tube, a heating plate, a heating belt, and an electromagnetic heating coil.

[0069] like Figure 1 , Figure 2 and Figure 4 As shown, the temperature compensation member 19 is attached to the periphery of the bottom 161 of the weight detection tray 15 , and the pressure sensor 112 is arranged in the middle of the bottom 161 of the weight detection tray 15 .

[0070] Optionally, the refrigerator 10 further includes a fan 111. The fan 111 is arranged in the thawing chamber 12 corresponding to the condenser 13.

[0071] like Figure 1 As shown, the fan 111 is arranged in parallel with the condenser 13 and is disposed on one side of the condenser 13. The fan 111 is used to drive the airflow, accelerate the airflow on the surface of the thawed items, and accelerate the thawing. At the same time, the fan 111 can reduce the temperature difference at various positions in the thawing chamber so that the thawed items are thawed evenly. It can also accelerate the heat dissipation speed of the condenser 13 and improve the refrigeration effect of the freezer 10.

[0072] In some embodiments, the fan 111 is controlled by the weight detection tray 15. When the weight detection tray 15 detects the weight of the items to be thawed, the control device starts the fan 111 to assist in thawing.

[0073] Optionally, the refrigerator 10 further includes a solenoid valve 17. The solenoid valve 17 is disposed at the refrigerant inlet of the condenser 13, and the solenoid valve 17 is used to control the refrigerant flow rate.

[0074] like Figure 1 As shown, the solenoid valve 17 is disposed at the refrigerant inlet of the condenser 13 , and the solenoid valve 17 can be controlled to open the refrigerant inlet of the condenser 13 , or controlled to close the refrigerant inlet of the condenser 13 .

[0075] In this embodiment, the electromagnetic valve 17 is provided to connect or disconnect the refrigerant inlet of the condenser 13 through the electromagnetic valve 17, thereby changing the working state of the condenser 13. In this way, it can be avoided that during the operation of the refrigerator 10, the condenser 13 in the thawing chamber 12 is always in the working state, the chamber to be thawed 12 is heated, and the temperature in the chamber to be thawed is too high.

[0076] Optionally, the refrigerator 10 further includes a thermostat 110. The thermostat 110 is connected to the thawing chamber 12 and the solenoid valve 17 respectively, and controls the switch state of the condenser 13 according to the temperature of the thawing chamber 12.

[0077] like Figure 1 As shown, during the thawing process, the temperature controller 110 probe detects the temperature in the thawing chamber 12 in real time. When the temperature in the thawing chamber 12 rises to a temperature greater than the second preset temperature, the solenoid valve 17 is controlled to be disconnected, and the residual heat of the condenser 13 is used to thaw the items to be thawed in the thawing chamber 12.

[0078] Optionally, the weight detection tray 15 includes a placing tray 16 and a pressure sensor 112. The placing tray 16 opens upward and is used to place the thawed objects; the pressure sensor 112 is arranged below the placing tray 16.

[0079] In some embodiments, the second preset temperature includes 20°C, 25°C, 30°C, 35°C, 40°C, 45°C, 50°C, 55°C, and 60°C.

[0080] In some embodiments, the weight detection tray 15 also includes a gravity sensor or a gravity sensor.

[0081] In the present disclosure, the force value detected by the gravity sensor is used to represent the weight, or the force value detected by the pressure sensor 112 is used to represent the weight, or the weight value is directly detected by the weight sensor.

[0082] Optionally, the bottom 161 of the storage tray 16 is made of metal.

[0083] In this embodiment, the metal material conducts heat quickly and is heated evenly, so the items to be thawed can be thawed quickly.

[0084] In some embodiments, there are multiple weight detection trays 15 , and each weight detection tray 15 is correspondingly provided with a temperature compensation member 19 .

[0085] In this embodiment, multiple items to be thawed can be thawed at the same time. When any weight detection tray 15 detects an item to be thawed, the condenser 13 is controlled to start. At the same time, when the weight detection tray 15 detects that the weight change speed of the corresponding item to be thawed is less than the first preset speed, the corresponding temperature compensation member 19 is controlled to start, so as to heat the weight detection tray 15 with a slow thawing speed.

[0086] Exemplarily, the thawing process includes the following steps:

[0087] Place the food on the tray 16, preferably in the middle.

[0088] The placing tray 16 is pressed down by the food and contacts the pressure sensor 112 or the weight sensor or the gravity sensor. The pressure sensor 112 or the weight sensor or the gravity sensor senses the items to be thawed, and the control device controls the condenser 13 to turn on and controls the fan 111 to turn on to thaw the items to be thawed.

[0089] The temperature sensor 18 detects that the temperature in the thawing chamber 12 is lower than the first preset temperature and the weight of the items to be thawed is greater than the preset weight, and controls the opening of the temperature compensation element 19 to accelerate the thawing.

[0090] The solenoid valve 17 detects that the temperature in the thawing chamber 12 is greater than the second preset temperature, and controls the condenser 13 to be closed.

[0091] Exemplarily, preheating the thawing compartment includes the following steps:

[0092] The temperature sensor detects that the temperature in the thawing chamber 12 is lower than the first preset temperature, and controls the condenser 13 to be turned on to preheat the thawing chamber 12 .

[0093] The temperature sensor detects that the temperature in the thawing chamber 12 is greater than the second preset temperature, and controls the condenser 13 to be closed.
