As for a refrigerator with a refrigerating chamber above the freezing chamber, a user needs to bend down to open the door body of the freezing chamber upon taking out of ice. To enable the user to conveniently take ice, an independent ice-making chamber is disposed in the refrigerating chamber or a door body of the refrigerating chamber of some conventional refrigerators, the ice maker is disposed in the ice-making chamber, and a dispenser associated with the ice maker is disposed on an outer side of the door body. The cold air of the freezing chamber and the evaporator chamber is introduced through an air duct into the air-making chamber to achieve the supply of cold to the ice maker. Such an ice-making manner is also referred to as air-cooled ice making.

[0003] However, the ice-making efficiency in the air-chilled ice-making manner is low, and the air duct occupies a large space, thus occupying the storage space of the refrigerator itself. For this reason, there occurs a manner of making ice through direct contact between the refrigeration pipeline and the ice-maker, and the manner is referred to as direct-cooling ice-making. The direct-cooling ice-making has advantages such as quick ice making and a small occupation of space. However, since the space of the ice-making compartment is small and the structure of the ice maker itself is complicated, it is very troublesome when the ice maker is mounted.

[0023] Further referring to FIG 2 and FIG 3, the ice-making assembly 100 comprises a water draining tray 45 fixed below the ice mold 10, one end of the water draining tray 45 forms a water outlet 451, at least two upwardly-protruding support ribs 452 are provided on the water draining tray 45, and the support ribs 452 contact the heating wire 30 in a thermally-conductive manner and fix a portion of the heating wire 30 to the ice mold 10. In the present embodiment, the refrigerant pipe 20 is arranged in a U-shape at the bottom of the ice mold 10, 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 furthermore, the heating wire 30 is located on an outer side of the U-shape of the refrigerant pipe 20. The support ribs 452 and the water draining tray 45 are integrally arranged and may be made of a thermally conductive material, for example a metallic material, preferably a water draining tray made of aluminum, and may simultaneously absorb the heat of the heating wire 30 to melt the frost of the water draining tray 45. Four support ribs 452 are preferably provided. The four support ribs are arranged at an interval in the transverse direction and the front-rear direction respectively. As such, a space is left between the water draining tray 45 and the bottom of the ice mold 10, and forms an airflow chamber 44 which is through from one end to the other end of the ice mold 10, air may perform heat exchange with the refrigerant pipe 20 and the ice mold 10 upon flowing through the airflow chamber 44 to form cold air which may supply cold for the ice bin disposed below the ice-making assembly 100 to prevent the stored ice bins from melting. Either the refrigerant pipe 20 or the heating wire 30 performs heat exchange in a direct contact manner, so that the efficiency in transferring the cold and heat is higher and thereby the ice-making efficiency is greatly improved.

The overall structure is more compact so that the space in the ice-making chamber can be saved.

[0025] In the present embodiment, preferably, the fins comprise a first fin 421 and a second fin 422 corresponding to two straight sides of the U-shape of the refrigerant pipe 20, and a third fin 423 located between the first fin 421 and second fin 422, and a portion of the engaging portion 41 corresponding to the third fin 423 directly contacts the ice mold 10.

A plurality of water draining holes 411 are provided on the engaging portion 41 at an interval. The plurality of water draining holes 411 are disposed symmetrically relative to the third fin 423, and a portion of the refrigerant pipe 20 is exposed from the plurality of water draining holes 411, thereby enabling the frost formed on the refrigerant pipe 20 and the ice mold 10 to completely melt into water upon heating for drainage, preventing icicles from forming on the contact surface of the refrigerant pipe 20 and the engaging portion 41 and affecting normal refrigeration. The water draining holes 411 may be provided evenly at an interval from one end to the other end of the ice mold 10, and a width of the water draining holes 10 may be substantially equal to a spacing between two rows of water draining holes. The heat-dissipating member 40 may be mounted on the ice mold 10 via a fixing member such as a screw or bolt, or snap-fitted with the ice mold via a snap, or connected with the ice mold in other connection manners.

[0026] Furthermore, the ice-making assembly further comprises a bottom cover 50 fixedly connected to the ice mold 10. The bottom cover 50 comprises a bottom wall 51 and a first side wall 52 and a second side wall 53 extending upwardly along the front and rear of the bottom wall 51 respectively, the water draining tray 45 is fixed between the first side wall 52 and second side wall 53, a protruding rim 54 protruding upwardly is provided at both ends of the bottom cover 50 in a direction from one end to the other end of the ice mold 10, and the water draining tray 45 is sandwiched between the two protruding rims 54; the first side wall 52, second side wall 53 and the two protruding rims 54 achieve accurate positioning of the water draining tray 45 relative to the bottom cover 50 in two directions, and the water draining tray 45 is positioned and fixed more reliably. In addition, the edge of the water draining tray 45 has an upwardly-extending edge 455, the first side wall 52 and second side wall 53 are respectively provided with a plurality of barbs 535, and the water draining tray 45 is snap-fitted with the plurality of barbs 535 via the edge 455 and fixed with the bottom cover 50. In addition, a thermal insulation panel 55 may be disposed between the bottom cover 50 and the water draining tray 45 to insulate the heat transfer from the water draining tray 45 to the bottom cover 50 and prevent frost from being formed on the bottom cover 50.

[0027] 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 side wall 52 and second side wall 53, and one end of the bottom cover 50 is connected to the first edge 151 and second edge 152; at least support ribs 452 comprise two first support ribs 453 adjacent to the other end of the bottom cover 50, i.e., adjacent to one end of the water outlet 45, and the two first support ribs 453 are respectively connected to the first edge 151 and second edge 152. Specifically, the bottom cover 50 and the first edge 151 are connected via a screw 16 by penetrating the bottom cover 50 and the first edge 151, and the bottom cover 50 is snap-fitted with the second edge 152; preferably, a hook 1521 is disposed at an end of the second edge 152, and correspondingly a catching block 531 is disposed at an end of the second side wall 53. Upon assembling, the catching block 531 is snap-fitted on a hook 1521 to achieve the snap-fitting of the bottom cover 50 and second edge 152. A post 4531 extends from a side of the two first support ribs 453 facing away from each other, a hook portion 155 extends respectively from the first edge 151 and second edge 152, and the post 4531 can extend into the hook portion 155 and rotate and move in the hook portion 155. Upon assembling, the refrigerant pipe 20 is fixed to the ice mold 10 by the heat-dissipating member 40, the bottom cover 50 and the water draining tray 45 are pre-assembled together, the post 4531 is docked with the hook portion 155 so that the bottom cover 50 and the water draining tray 45 together first rotate about the post 4531 and then move along the hook portion 155 so that the bottom cover 50 is snap-fitted with the second edge, finally, the bottom cover 50 and ice mold 10 are fixed by running the screw 16 through the bottom cover 50 and first edge 151, thereby achieving the mounting of the ice-making assembly 100. The whole process is very convenient and quick. Furthermore, the heat transfer of the refrigerant pipe 20 and heating wire 30 to the ice mold 10 can be achieved reliably, and meanwhile the refrigerant pipe 20 and ice mold 10 can also achieve the heat exchange with the air in the airflow chamber 44, thereby facilitating supplying cold to other portions. In addition, upon deicing, the frost of the water draining tray 45 may also be melted with the heat of the heating wire 30, and the water resulting from the melting of the frost may be directly drained through the water outlet 451. 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.

[0028] Further referring to FIGS. 1-3, an ice guide 17 is fixedly connected at a front end of the ice mold 10, a guide rib 511 extending in a lengthwise direction of the first side wall 51 is disposed on an outer side of the first side wall 51 of the bottom cover 50, and the ice guide 17 extends downwards to a position flush with the guide rib 511, which may help a user to know a rough mounting position upon mounting the bottom cover 50. In addition, in order to facilitate connecting the ice guide 17, the ice guide 17 may be first connected to the ice mold 10, and an avoidance hole 171 may be provided on the ice guide 17 to help the screw 16 to run through to connect the bottom cover 50 with the ice mold 10. 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.

[0029] Frost will be formed on the bottom of the refrigerant pipe 20 and the ice mold 10. As the heating wire 30 is activated to de-ice, the water draining tray 45 meanwhile absorbs heat to melt the frost, and the water resulting from the melting of the frost directly falls into the water draining tray 15; in order to speed up water drainage, the water draining tray 45 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 being in a range of about 0.5-2.5 degrees. Furthermore, the water draining tray is inclined downwards in a front-rear direction, with an inclination angle being in a range of about 3-5 degrees. In order to further enhance the utilization rate of the cold of the refrigerant pipe, a height by which the plurality of fins extend downward may match the inclination direction of the water draining tray, that is to say, the distance from the bottoms of the fins to the water draining tray in the transverse direction and the front-rear direction is substantially the same, i.e., the bottoms of the plurality of fins are also inclined consistent with the water draining tray, so that the contact area of the fins with the air in the airflow chamber 60 is larger. The water outlet 451 is disposed at an end of the water draining tray away from the driving mechanism 60 and at a rear end of the water draining tray 45, i.e., at the lowest part of the water draining tray 45, so that the water resulting from the melting of the frost can be sufficiently drained. Furthermore, a water blocking edge 456 is provided at an end of the water draining tray 45 away from an end of the driving mechanism 60 to prevent overflow when the water resulting from the melting of the frost is excessive.

[0030] 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 integrally forms an upwardly-extending back plate 157, a mounting structure is provided on the back plate 157 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 158, a water filling trough 18 is disposed on an outer side of the end plate 158 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 18 is communicated with the ice cells. The water filling tough 18 and the ice mold 10 are also integrally formed, thereby avoiding the problem of water leakage during the water filling process.

[0031] In the ice-making assembly according to the above-mentioned embodiment, a tool needn't be used upon mounting the refrigerant pipe 20 together with the ice mold 10 and separating the refrigerant pipe 20 from the ice mold 10; upon mounting, the only thing to do is rotating the heat-dissipating member 40 in engagement with the refrigerant pipe 20, and the refrigerant pipe 20 is fixed relative to the ice mold 10.
