[0025] The present embodiment provides a refrigeration and freezing device 10 , which includes a housing 100 , an opening and closing member 200 , and at least one heat transfer pipe 300 . Figure 1 is a side cross-sectional view of a refrigerator-freezer 10 according to an embodiment of the present invention, Figure 2 yes Figure 1 A schematic partial enlarged view of area A is shown. Figure 3 is a top cross-sectional view of a refrigerator-freezer 10 according to an embodiment of the present invention ( Figure 1 , Figure 3 The evaporator chamber cover plate and internal components of the storage space, such as drawers, shelves, etc., are hidden.

[0026] The box 100 is provided with a compressor 110, an evaporator 120, and a heat storage device 130 for storing part of the heat emitted by the compressor 110. The heat storage device 130 stores part of the heat emitted by the compressor 110, thereby improving the refrigeration effect of the refrigeration and freezing device 10 and extending the life of the compressor 110. In some embodiments, the heat storage device 130 may be made of a metal material. In other embodiments, the heat storage device 130 may include a metal shell, and a material with a large specific heat capacity, such as water, may be provided in the metal shell. Since such a heat storage device 130 capable of storing heat is known to those skilled in the art, it will not be described in detail here.

[0027] The opening and closing member 200 is in contact with the heat storage device 130. One end of the at least one heat transfer heat pipe 300 is in contact with the opening and closing member 200, and the other end of the at least one heat transfer heat pipe 300 is connected to the evaporator 120. A heat pipe is a structure composed of a tube shell, a liquid absorption core and an end cover, and a refrigerant is arranged in the tube. When the temperature of one end is higher and the temperature of the other end is lower, heat will be transferred from the end with higher temperature to the end with lower temperature. Since the heat pipe itself is well known to those skilled in the art, it will not be described in detail here.

[0028] The opening and closing member 200 is configured to form a heat flow path between the heat storage device 130 and the at least one heat transfer heat pipe 300 when the evaporator 120 is defrosting, so that the part of the heat stored in the heat storage device 130 is transferred to the evaporator 120 through the opening and closing member 200 and the at least one heat transfer heat pipe 300.

[0029] Those skilled in the art can understand that since the temperature of the evaporator 120 is relatively low, ice will form on the surface of the evaporator 120 after the evaporator 120 has been running for a period of time, thereby affecting the refrigeration effect. Therefore, the evaporator 120 will be defrosted after running for a period of time to remove the frost on the surface of the evaporator 120. The existing refrigeration and freezing devices heat the evaporator by heating wires for defrosting. Such refrigeration and freezing devices that use heating wires to defrost the evaporator are not energy-saving and environmentally friendly.

[0030] The refrigeration and freezing device 10 provided in this embodiment does not need to be provided with a heating wire, and the evaporator 120 can be defrosted when the evaporator 120 is in defrosting operation, so that the refrigeration and freezing device 10 is more energy-saving and environmentally friendly.

[0031] The opening and closing member 200 can also be configured to disconnect the heat flow path between the heat storage device 130 and the at least one heat transfer heat pipe 300 when the evaporator 120 is in cooling operation, so as to prevent the heat stored in the heat storage device 130 from being transferred to the evaporator 120. This ensures that the evaporator 120 can generate sufficient cooling capacity when in cooling operation.

[0032] Figure 4 1 is a schematic structural diagram of an opening and closing member 200 of a refrigerator-freezer 10 according to an embodiment of the present invention. The opening and closing member 200 has a heat insulating section 210 made of a heat insulating material (eg, plastic) and a heat conducting section 220 made of a heat conducting material (eg, metal).

[0033] The refrigeration and freezing device 10 may further include a driving motor 400 , which is disposed at a position corresponding to the opening and closing member 200 and is used to drive the opening and closing member 200 to rotate. The driving motor 400 and the opening and closing member 200 may both be disposed in the housing 100 .

[0034] In some embodiments, the output shaft of the driving motor 400 is connected to the gear, the opening and closing member 200 is disc-shaped, the opening and closing member 200 has a circular upper end surface, a circular lower end surface, and a side wall connecting the circular upper end surface and the circular lower end surface, and the side wall has opening and closing member teeth meshing with the teeth of the gear, and the driving motor 400 drives the gear to rotate, thereby driving the opening and closing member 200 to rotate. Among them, the heat conducting section 220 can be a disc-shaped with a diameter of 1 / 4 of the diameter of the opening and closing member 200, a disc-shaped with a diameter of 1 / 2 of the diameter of the opening and closing member 200, etc.

[0035] In other embodiments, the output shaft of the drive motor 400 is directly connected to the opening and closing member 200, and the opening and closing member 200 may be disc-shaped or may be other shapes, such as a plate-shaped opening and closing member 200 formed by a rectangular end surface extending in a direction perpendicular to the rectangular end surface. When the opening and closing member 200 is disc-shaped, the opening and closing member 200 has a circular upper end surface, a circular lower end surface, and a side wall connecting the circular upper end surface and the circular lower end surface, the output shaft of the drive motor 400 may connect the center of the circular upper end surface and the center of the circular lower end surface, the heat conduction section 220 may be semi-disc-shaped (formed by a semi-circular end surface extending in a direction perpendicular to the end surface, the diameter of the semi-circle may be smaller than the diameter of the opening and closing member 200, the center of the semi-circle may coincide with the center of the opening and closing member 200, and the heat conduction section 220 may also be a fan-shaped or other shape), and the other areas of the opening and closing member 200 are the heat insulation section 210.

[0036] The output shaft of the driving motor 400 may not be connected to the center of the circular upper end surface and the center of the circular lower end surface, but may be connected to an area that is a certain distance from the center of the circular upper end surface and an area that is a certain distance from the center of the circular lower end surface. The heat conducting section 220 may not be a semi-disc shape. For example, it may be a disc shape with a diameter that is 1 / 4 of the diameter of the opening and closing member 200 and does not pass through the center of the opening and closing member 200, a disc shape with a diameter that is 1 / 2 of the diameter of the opening and closing member 200 and does not pass through the center of the opening and closing member 200, etc.

[0037] When the evaporator 120 is in defrosting operation, the opening and closing member 200 is respectively abutted against the heat storage device 130 and the at least one heat transfer heat pipe 300 through the heat conduction section 220 to form the heat flow path, and when the evaporator 120 is in refrigeration operation, the opening and closing member 200 is respectively abutted against the heat storage device 130 and the at least one heat transfer heat pipe 300 through the heat insulation section 210 to disconnect the heat flow path.

[0038] This method of driving the opening and closing member 200 to rotate by driving the motor 400 can accurately form or break the heat flow path.

[0039] The end of the at least one heat transfer heat pipe 300 that abuts against the opening and closing member 200 may be formed with a connection portion 310 that matches the shape of the heat conduction section 220, and the connection portion 310 is made of a heat conductive material. For example, when the heat conduction section 220 is in a disc shape, the connection portion 310 is also in a disc shape, and when the heat conduction section 220 is in a semi-disc shape, the connection portion 310 is also in a semi-disc shape. The connection portion 310 can increase the contact area between the at least one heat transfer heat pipe 300 and the heat conduction section 220, and prevent any heat transfer heat pipe 300 from shifting when the opening and closing member 200 rotates.

[0040] The housing 100 may define a compressor chamber 111 for accommodating the compressor 110. The refrigerating and freezing device 10 may further include a condenser (not shown) and a throttling element (not shown), etc. The condenser may also be arranged in the compressor chamber 111. The evaporator 120 is connected to the compressor 110, the condenser, and the throttling element via a refrigerant pipeline to form a refrigeration cycle circuit, and the temperature is reduced when the compressor 110 is started to cool the air flowing through it. Since the refrigeration principle of the refrigerating and freezing device 10 is well known to those skilled in the art, it will not be described in detail here.

[0041] The refrigeration and freezing device 10 may also include at least one heat-absorbing heat pipe 500, one end of the at least one heat-absorbing heat pipe 500 is arranged in the press chamber 111, and the other end of the at least one heat-absorbing heat pipe 500 is connected to the heat storage device 130, and the at least one heat-absorbing heat pipe 500 is used to absorb part of the heat and transfer the part of the heat to the heat storage device 130.

[0042] The heat absorbing heat pipe 500 can quickly transfer heat to the heat storage device 130 to prevent the temperature of the press chamber 111 from rising too quickly.

[0043] In some embodiments, the heat storage device 130 may also be disposed in the compression chamber 111 to directly absorb part of the heat emitted by the compressor 110 in the compression chamber 111 .

[0044] The at least one heat absorbing heat pipe 500 may be multiple, and one end of the at least one heat absorbing heat pipe 500 disposed in the compressor chamber 111 surrounds a portion of the circumference of the compressor 110. That is to say, the at least one heat absorbing heat pipe 500 is a plurality of heat absorbing heat pipes 500 disposed in the compressor chamber 111 and one end of the heat absorbing heat pipe 500 surrounds a portion of the circumference of the compressor 110, thereby improving the heat absorption efficiency of the at least one heat absorbing heat pipe 500.

[0045] The cabinet 100 may include a storage liner 140 , wherein an evaporator chamber 121 for accommodating the evaporator 120 is defined at a lower portion of the storage liner 140 , and a storage compartment 141 located above the evaporator chamber 121 is defined in the storage liner 140 .

[0046] The storage liner 140 may include a freezer liner located at the bottom and a refrigeration liner located at the top. The evaporator chamber 121 is arranged at the lower part of the inner side of the freezer liner, occupying the lower space inside the freezer liner. The position of the storage compartment 141 (for example, the freezer compartment above the evaporator chamber 121) located above the evaporator chamber 121 in the freezer liner can be effectively raised, thereby reducing the degree of bending of the user when taking items into and out of the freezer, thereby improving the user's experience.

[0047] The housing 100 may define a heat storage chamber 131 for accommodating a heat storage device 130, and the heat storage chamber 131 is located below the evaporator chamber 121. When the heat of the heat storage device 130 reaches a maximum, another portion of the heat of the press chamber 111 will diffuse to the space around the heat storage chamber 131 through the at least one heat-absorbing heat pipe 500. By arranging the heat storage chamber 131 below the evaporator chamber 121, it is possible to avoid discomfort to the user caused by the other portion of heat, thereby improving the user experience.

[0048] The heat storage chamber 131 may have an opening, and the end of the at least one heat absorbing heat pipe 500 connected to the heat storage device 130 closes the opening. Therefore, when the heat stored in the heat storage device 130 reaches the maximum value, another part of the heat emitted by the compressor 110 can be transferred to the air around the opening through the at least one heat absorbing heat pipe 500, so as to further improve the working efficiency of the compressor 110. In other embodiments, the heat storage chamber 131 may not have an opening, and the other part of the heat is transferred to the air in the heat storage chamber 131.

[0049] Preferably, the opening can be located below the heat storage chamber 131, and the press chamber 111 can be located behind the heat storage chamber 131, so that when the heat stored in the heat storage device 130 reaches the maximum value, the other part of the heat emitted by the compressor 110 can be transferred to the lowest position, thereby improving the user experience. Each heat-absorbing heat pipe 500 extends downward in the press chamber 111 to the inner surface of the outer shell of the box (the box 100 may include an outer shell, a storage liner 140, and a foam disposed between the outer shell and the storage liner 140), and then extends forward to close the opening.

[0050] Furthermore, the positional relationship between the evaporator chamber 121 and the heat storage chamber 131 can reduce the length of the heat transfer heat pipe 300, thereby reducing costs and reducing heat loss.

[0051] The storage liner 140 may also include a refrigeration liner located at the upper portion, and the refrigeration liner defines a refrigeration chamber. As is well known to those skilled in the art, the temperature in the refrigeration chamber is generally between 2°C and 10°C, preferably between 4°C and 7°C. The temperature range in the freezer chamber is generally between -22°C and -14°C. Different types of items have different optimal storage temperatures and different suitable storage locations. For example, fruit and vegetable foods are suitable for storage in the refrigeration chamber, while meat foods are suitable for storage in the freezer chamber.

[0052] In some embodiments, the press chamber 111 may be located behind the heat storage chamber 131 and the evaporator chamber 121. The box body 100 may include an outer shell, and a foam is provided between the outer shell and the storage liner 140, and the at least one heat transfer heat pipe 300, the at least one heat absorption heat pipe 500 and the heat storage device 130 are partially in contact with the foam to reduce heat loss.

[0053] The at least one heat transfer heat pipe 300 may be multiple, and one end connected to the evaporator 120 is evenly spaced along one side of the evaporator 120. That is, the at least one heat transfer heat pipe 300 is a plurality of heat transfer heat pipes 300 whose one end connected to the evaporator 120 is evenly spaced along one side of the evaporator 120, so that the evaporator 120 is evenly heated during defrosting operation, thereby improving the defrosting effect of the evaporator 120. Specifically, the at least one heat transfer heat pipe 300 whose one end connected to the evaporator 120 is evenly spaced along one side of the lateral direction or one side of the front-rear direction of the evaporator 120.

[0054] The refrigeration and freezing device 10 may be a built-in refrigerator. Those skilled in the art will appreciate that since the space between the rear and side of the built-in refrigerator and the indoor cabinet or wall is small, it is not conducive to heat dissipation. Therefore, the heat storage device 130 can more effectively solve the heat dissipation problem of the built-in refrigerator and can more efficiently utilize its heat.

[0055] The refrigeration and freezing device 10 of this embodiment includes a housing 100, an opening and closing member 200, and at least one heat transfer heat pipe 300. The housing 100 is provided with a compressor 110, an evaporator 120, and a heat storage device 130 for storing part of the heat emitted by the compressor 110. The heat storage device 130 stores part of the heat emitted by the compressor 110, thereby improving the refrigeration effect of the refrigeration and freezing device 10 and extending the life of the compressor 110. The opening and closing member 200 is in contact with the heat storage device 130. One end of the at least one heat transfer heat pipe 300 is in contact with the opening and closing member 200, and the other end is connected to the evaporator 120. The opening and closing member 200 is configured to form a heat flow path between the heat storage device 130 and the at least one heat transfer heat pipe 300 when the evaporator 120 is defrosting, so that the part of the heat stored in the heat storage device 130 is transferred to the evaporator 120 through the opening and closing member 200 and the at least one heat transfer heat pipe 300. The refrigeration and freezing device 10 can perform a defrosting operation on the evaporator 120 when the evaporator 120 is defrosting without providing a heating wire, so that the refrigeration and freezing device 10 is more energy-saving and environmentally friendly.

[0056] The evaporator chamber 121 can be arranged at the lower part of the inner side of the freezer liner, occupying the lower space inside the freezer liner, which can effectively raise the position of the storage compartment 141 (for example, the freezer compartment above the evaporator chamber 121) located above the evaporator chamber 121 in the freezer liner, reduce the degree of bending when the user takes out and puts items in the freezer, and improve the user experience. In addition, since the heat storage chamber 131 is located below the evaporator chamber 121, that is, when the heat stored in the heat storage device 130 reaches the maximum value, another part of the heat emitted by the compressor 110 can be transferred to the air around the lower opening through the at least one heat-absorbing heat pipe 500, so as to avoid the discomfort caused by the other part of the heat to the user and improve the user experience.

[0057] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
