The terms indicating spatial relative positions may be intended to include different orientations besides the orientations shown in the figures in use or operation of the device.
Referring to FIG 1 through FIG 4, a preferred embodiment of the present invention provides an ice-making assembly 100 comprising an ice mold 10, and a refrigerant pipe 20 and a heating wire 30 located at a bottom of the ice mold 10, wherein the ice mold 10 has a plurality of ice cells for containing ice-making water, the refrigerant pipe 20 extends from one end to the other end of the ice mold 10, and the heating wire 30 is spaced apart from the refrigerant pipe 20, and preferably spaced apart from the refrigerant pipe 20 in a direction substantially perpendicular to an extension direction of the ice mold 20. The refrigerant pipe 20 is configured to supply cold to the ice mold 10 to freeze water in the ice cells, and the heating wire 30 is configured to supply heat to the ice mold 10 to facilitate release of ice cubes from the ice mold 10. In the present embodiment, a direction in which the ice mold extends lengthwise from one end to the other end is taken as a transverse direction, a side from which the ice cubes are released from the ice mold is taken as a front side, the opposite side is taken as a rear side, and a direction perpendicular to the transverse direction and the front-rear direction is taken as a vertical direction.
The ice-making assembly 100 further comprises a heat-conducting member 40 and a bottom cover 50 surrounding the outside of the heat-conducting member 40, wherein the heat-conducting member 40 is disposed between the ice mold 10 and the bottom cover 50, the refrigerant pipe 20 and the heating wire 30 are positioned between the ice mold 10 and the heat-conducting member 40, and the heat-conducting member 40 supports at least a portion of the refrigerant pipe 20 and at least a portion of the heating wire 30 such that the at least a portion of the refrigerant pipe 20 and the at least a portion of the heating wire 30 are in direct contact with the ice mold 10 to transfer cold and heat to the ice mold 10. With the heat exchange being performed by direct contact, the transfer of heat and cold is more efficient, thereby greatly improving the ice-making efficiency.
Specifically, the heat-conducting member 40 comprises a top wall 41 adjacent to the ice mold 10, an opposite bottom wall 42 and two side walls 43 connecting the top wall 41 with the bottom wall 42, wherein the top wall 41, the bottom wall 42 and the two side walls 43 enclose an airflow chamber 44 which is through in a direction from one end to the other end of the ice mold 10, heat-dissipating ribs 45 extending from the top wall 41 to the bottom wall 42 are provided in the airflow chamber 44, a water outlet 421 is formed at an end of the bottom wall 42, the bottom cover 50 surrounds the bottom wall 42 and the two side walls 43, and the heat-conducting member 40 is fixed to the ice mold 10 via the bottom cover 50. In this way, during assembly, the heat transfer of the refrigerant pipe 20 and the heating wire 30 to the ice mold 10 may be achieved only by placing the refrigerant pipe 20 and the heating wire 30 between the ice mold 10 and the heat-conducting member 40, and connecting the bottom cover 50 with the ice mold 10. The mounting is very convenient. Meanwhile, the heat-conducting member 40 and the heat-dissipating ribs thereof can also achieve heat exchange with the air in the airflow chamber, thereby facilitating the supply of cold to other portions such as an ice bin below the ice-making assembly 100 to prevent the stored ice cubes from melting. In addition, upon deicing, the heat-conducting member 40 may also melt the frost by virtue of the heat of the heating wire 30, and the water resulting from the melting of the frost may be directly discharged through the water outlet 421. The manner in which the refrigerant pipe 20 and the heating wire 30 simultaneously contact the ice mold 10 and the heat-conducting member 40 enables a higher utilization ratio of cold and heat and a faster heat transfer, thereby enabling an improvement in ice-making efficiency. In addition, if the ice mold needs to be cleaned, regardless of disassembly or installation, it is only necessary to connect the ice mold with the bottom cover by aligning relevant parts in position, so that the installation is very convenient.
Referring to FIG 3, the top wall 41 of the heat-conducting member 40 is provided with a first groove 411 and a second groove 412 respectively matching the outer shapes of the refrigerant pipe 20 and the heating wire 30, and a portion of the refrigerant pipe 20 is received in the first groove 411 and a portion of the heating wire 30 is received in the second groove 412. A portion of the refrigerant pipe 20 in contact with the ice mold 10 is constructed in a U-shape, the heating wire 30 is also constructed in a U-shape, the refrigerant pipe 20 and the heating wire 30 are arranged oppositely, i.e., the two U-shapes open in opposite directions, and the refrigerant pipe 20 is located on an inner side of the U-shape of the heating wire 30. The ice-making assembly 100 further comprises a driving mechanism 60 at an end of the ice mold 10, and the driving mechanism 60 is used to bring an ice discharger 70 on the ice mold 10 to rotate to perform deicing. An open end of the U-shape of the heating wire 30 faces towards the driving mechanism 60 to facilitate making electrical connection. The open end of the U-shape of the refrigerant pipe 20 faces away from the driving mechanism 60 to facilitate connection with the refrigeration pipeline. In order to accelerate the conduction of the cold, the heat-dissipating ribs 45 are arranged at positions corresponding to the first grooves 411, so that the heat-dissipating ribs 42 are closer to the refrigerant pipe 20, thereby facilitating the absorption of the cold of the refrigerant pipe 20, and thereby improving the refrigerating efficiency. The heat-conducting member 40 is preferably made of a metal, such as an integrally-formed aluminum member. The heat-conducting member 40 is convenient to manufacture and meanwhile has high heat conductivity.
In addition, in order to further improve the heat exchange efficiency between the refrigerant pipe 20 and the ice mold 10, the top wall 41 of the heat-conducting member 10 is further provided with a convex portion 413 extending in a direction from one end to the other end of the ice mold 10, the convex portion 413 is in direct contact with the bottom of the ice mold 10, the convex portion 413 is located in an interior of the U-shape of the refrigerant pipe, and the heat-conducting member 40 receives the cold on the refrigerant pipe 20 and further conducts the cold to the ice mold 10 again through the convex portion 413, thereby quickening the conduction of col and improving the ice-making efficiency. Furthermore, a surface of the convex portion 413 facing the airflow chamber forms a groove 414, that is, a wall thickness of the top wall 41 of the heat-conducting member 10 is substantially uniform, so that the surface area in contact with the airflow can be increased, thereby improving the heat exchange efficiency. The refrigerant pipe 20 is wrapped by the ice mold 10 and the heat-conducting member 40. Frost will be formed on a surface inside the airflow chamber 44 of the heat-conducting member 40. As the heating wire 30 is activated to de-ice, the heat-conducting member 40 meanwhile absorbs heat to melt the frost, and the water resulting from the melting of the frost flows to the bottom wall 42 directly along the surface inside the airflow chamber 44; in order to speed up water drainage, the bottom wall 42 may be arranged to be inclined downwards in a direction from one end of the ice mold 10 connected to the driving mechanism 60 to the other end, with an inclination angle α being in a range of about 0.5-2.5 degrees. Furthermore, the bottom wall 42 is inclined downwards in a front-rear direction, with an inclination angle β being in a range of 3-5 degrees. The water outlet 421 is disposed at an end of the bottom wall 42 away from the driving mechanism 60 and at a rear end of the heat conducting member 40, i.e., at the lowest part of the bottom wall 42, so that the water resulting from the melting of the frost can be sufficiently drained. Furthermore, a water blocking edge 423 is provided at an end of the bottom wall 42 away from an end of the driving mechanism 60 to prevent overflow when the water resulting from the melting of the frost is excessive.
Further referring to FIG 2 and FIG 3, the bottom cover 50 comprises a first enclosing wall 51 and a second enclosing wall 52 corresponding to the two side walls, wherein a snap-fitting protrusion 511 is provided on one of each enclosing wall and the corresponding side wall, and a snap-fitting slot 431 is provided on the other of each enclosing wall and the corresponding side wall, and the heat-conducting member 40 and the bottom cover 50 are fixedly connected via the snap-fitting protrusion 511 and the snap-fitting slot 431. Preferably, in the present embodiment, three snap-fitting slots 431 are disposed at an interval on each side wall 43 in an extension direction of the ice mold 10 from one end to the other end, and the first enclosing wall 51 and the second enclosing wall 52 are respectively provided with snap-fitting protrusions 511 corresponding to the snap-fitting slots 431. Upon mounting, it is only necessary to align the position the heat-conducting member 40 with the position of the bottom cover 50, and press the heat-conducting member 40 between the first enclosing wall 51 and the second enclosing wall 52, and mount the heat-conducting member 40 in position with the bottom cover 50 when a snap-fitting sound is heard. A thermal insulation panel 55 may be disposed between the bottom cover 50 and the bottom wall of the heat-conducting member 40 to insulate the heat transfer from the heat-conducting member 40 to the bottom cover 50 and prevent frost from being formed on the bottom cover 50.
In the direction of the bottom cover 50 from one end to the other end of the ice mold 10, a protruding rim 54 protruding upwards is disposed at both ends of the bottom cover 50. The heat-conducting member 40 is snap-fitted between the two protruding rims 54. The first enclosing wall 51, the second enclosing wall 52 and the two protruding rims 54 enable the accurate positioning of the heat-conducting member 40 relative to the bottom cover 50 in two directions, so that the positioning and the fixing of the heat-conducting member 40 is more reliable.
The ice-making assembly 100 further comprises a housing 15 fixed to the ice mold 10, wherein the housing 15 has a first edge 151 and a second edge 152 respectively corresponding to the first enclosing wall 51 and the second enclosing wall 52, a lug 153 provided with a snap-fitting hook or hook slot extends from the first edge 151 and the second edge 152 respectively, the two enclosing walls are respectively provided with a hook slot or snap-fitting hook, and the bottom cover 50 and the housing 15 are fixedly connected via the hook slot and snap-fitting hook. As such, the heat-conducting member 40 may be maintained in a relatively fixed position, thereby enabling the refrigerant pipe 20 and the heating wire 30 to keep in contact with the ice mold 10, so that the heat transfer is more reliable. In the present embodiment, preferably two lugs 153 extend downwards from the first edge 151 and the second edge 152, respectively, namely, two lugs 153 are provided at a front end of the ice mold 10, two lugs 153 are provided at a rear end of the ice mold 10, hook slots are provided on the lugs 153, and snap-fitting hooks are correspondingly provided on the two enclosing walls 51 and 52. An ice guide 16 is fixedly connected to the front end of the ice mold 10 to prevent falling ice cubes from hitting the snap-fitting hooks or the hook slots upon deicing. The ice guide 16 extends downwards to a position flush with the snap-fitting hooks.
The housing 15 and the ice mold 10 are integrally formed to simplify the installation of the entire ice-making assembly 100. The housing 15 has a front end and an opposite rear end, the rear end of the housing 15 forms an upwardly-extending back plate 155, a mounting structure is provided on the back plate 155 for mounting the ice-making assembly 100 inside the refrigerator, and the driving mechanism 60 may be mounted on the housing 15. As such, only the housing 15 needs to be fixedly connected to the refrigerator, so the mounting is more convenient. In addition, one end of the housing 15 away from the driving mechanism 60 forms an upwardly-extending end plate 156, a water filling trough 18 is disposed on an outer side of the end plate 156 relative to the ice mold 10, a water filling port communicated with an inner cavity of the ice mold 10 is disposed at a position of the water filling trough 18 adjacent to the ice mold 10, that is to say, the water filling trough is communicated with the ice cells.
