As shown in FIGs. 1 to 6, an embodiment of the present invention is to provide an ice-making assembly 100. The ice-making assembly 100 includes an ice mold 10, a refrigerant pipe 13, a heat conduction member 15, a bottom cover 50 and a wind baffle 30. The ice mold 10 has a plurality of ice trays 11 for containing ice-making water. The refrigerant pipe 13 extends from one end of the ice mold 10 to the other end of the ice mold 10, and is located at the bottom of the ice mold 10. The bottom cover 50 surrounds the heat conduction member 15. The heat conduction member 15 is arranged between the ice mold 10 and the bottom cover 50, and the refrigerant pipe 13 is located between the ice mold 10 and the heat conduction member 15. The heat conduction member 15 supports at least part of the refrigerant pipe 13, so that at least part of the refrigerant pipe 13 is in direct contact with the ice mold 10 to transfer cold energy to the ice mold 10. The heat conduction member 15 includes a top wall 151 adjacent to the ice mold 10. The bottom cover 50 includes a bottom wall 51 and two opposite side walls 50 connected to the bottom wall 51. The bottom wall 51 is opposite to the top wall 151. An airflow cavity 200 is defined by the bottom wall 51, the top wall and the two side walls 52 in a surrounding manner, and the airflow cavity 200 is provided to run through in a direction from one end of the ice mold 10 to the other end of the ice mold 10. The wind baffle 30 covers a side of the ice mold 10 away from the refrigerant pipe 13 and guides cold energy in the airflow cavity 200 to flow towards the plurality of ice trays 11.
In the present embodiment, an airflow inlet 201 of the airflow cavity 200 is communicated with an air outlet of an air passage of a refrigerator (not shown), so that an airflow blown from the air outlet of the air passage circulates from the airflow inlet 201 towards an airflow outlet 202 of the airflow cavity 200. Since the refrigerant pipe 13 and the heat conduction member 15 are both located in the airflow cavity 200, and at least part of the refrigeration pipe 13 is in contact with the heat conduction member 15, the cold energy in the refrigerant pipe 13 may be conducted through the heat conduction member 15 to air in the airflow cavity 200, forming cold air. The cold air is driven by an airflow blown from the air outlet of the air passage to flow toward the ice trays 11 at the airflow outlet 201. Because the wind baffle 30 covers the side of the ice mold 10 away from the refrigerant pipe 12, the wind baffle 30 blocks the flow of cold air from flowing in a direction away from the ice mold 10, and guides the cold air into a space between the wind baffle 30 and the ice trays 11. The cold air sinks into the ice trays 11 to cool the upper part of the ice-making water in the ice trays 11.
In other words, the wind baffle 30 guides cold energy in the airflow cavity 200 to flow between the air shield 30 and the ice trays 11, so that the cold energy in the cold air is transferred from top to bottom towards the ice trays 11. Therefore, the cold energy generated in the refrigerant pipe 13 can be used to the greatest extent to achieve rapid ice-making and shorten the ice-making time, so that the circulation time of a refrigerant in an air return pipe at a hinge is shortened, thereby avoiding the problems such as condensation and frost of the air return pipe.
In a preferred embodiment of the present invention, the wind baffle 30 is, for example, a C-shaped cover body. One side of the C-type cover body is pivotally connected to the ice mold 10, and the other side of the C-type cover body covers a side of the ice mold 10 away from the refrigerant pipe 13, so that a cold air circulation space is formed between the C-type cover body and the ice mold 10.
In a preferred embodiment of the present invention, the wind baffle 30 is rotatably arranged above the ice mold 10. For example, a rotating shaft 31 is arranged on the wind baffle 30, a side bracket of the ice mold 10 is provided with a rotating shaft hole 103, and the rotating shaft 31 is inserted into the rotating shaft hole 103, so that the wind baffle 30 is rotatably arranged above the ice mold 10. The wind baffle 30 may be rotatably arranged above the ice mold 10. When ice in the ice trays 11 is turned over and removed, the wind baffle 30 can be moved away from the ice trays 11 to avoid abnormal ice turning and removal caused by the wind baffle 30.
Specifically, the ice-making assembly 100 further includes an ice turning bar 12 and a cam 121. Two opposite ends of the ice turning bar 12 are rotatably connected to the side bracket of the ice mold 10. The ice turning bar 12 is located between the ice mold 10 and the wind baffle 30. The cam 121 is connected to the ice turning bar 12. The ice turning bar 12 rotates around the side bracket of the ice mold 10 to drive the cam 121 to rotate, so that the cam 121 pushes against the wind baffle 30 to rotate in a direction away from the ice mold 10. Preferably, the wind baffle 30 flips up and opens, exposing the ice trays 11.
In a preferred embodiment, the ice turning bar 12 is provided with a plurality of ice turning teeth, wherein the plurality of ice turning teeth is in one-to-one correspondence to the plurality of ice trays 11, so that corresponding ice cubes in the corresponding ice trays 11 are removed to an ice storage box (not shown). Therefore, a user can take the ice cubes out conveniently from the door body side through a distributor.
As shown in FIGs. 5 and 6, one end of the ice turning bar 12 is connected to a driving device 70. The cam 121 is arranged close to the driving device 70. In the present embodiment, the cam 121 is arranged close to the driving device 70 and is located at the end of the ice turning bar 12, without occupying any ice-making space of the ice trays 11.
In a preferred embodiment, the driving device 70 is, for example, an electric motor, and is contained inside a housing 60.
In a preferred embodiment, the cam 121 and the ice turning bar 12 are integrally formed.
As shown in FIGs. 2 and 6, the cam 121 is a flaky protrusion, wherein one end of the flaky protrusion protrudes towards the airflow outlet 202 of the airflow cavity 200. A bending wall 32 of the wind baffle 30 protrudes towards the airflow outlet 201, and shields at least part of the airflow outlet 202. Preferably, the bending wall 32 is located at the upper part of the airflow outlet 202. The bending wall 32 includes an extension 321, a shape of which is adapted with a shape of the cam 121 each other. For example, the extension 321 is an arc-shaped recess, an edge of the cam 121 is an arc-shaped protrusion, and the arc-shaped protrusion is assembled in the arc-shaped recess. The ice turning bar 12 rotates and drives the cam 121 to rotate, and the arc-shaped protrusion pushes against the arc-shaped recess, so that the wind baffle 30 rotates in a direction away from the ice mold 10.
In other embodiments of the present invention, the cam and the extension may also be in other shapes. That is, the cam only needs to contact and push against the extension during rotation, driving the wind baffle away from the ice mold.
As shown in FIGs. 2 and 4, the ice-making assembly 100 further includes an ice baffle 20. The ice baffle 20 includes a body 23 and a plurality of plates that is spaced apart and extends from one side of the body 23 toward the ice mold 10. The plurality of spaced-apart plates 21 is located between the wind baffle 30 and the ice trays 11. An air passage hole 22 is formed between any adjacent plates 21, and one air passage hole 22 corresponds to one ice tray 11.
Each air passage hole 22 is substantially stacked above the ice tray 11, and is connected to each other. When the cold air in the airflow cavity 200 enters a space between the wind baffle 30 and the ice trays 11 from the airflow outlet 202, the air passage holes 22 makes the cold air enter more directionally into the ice trays 11. Therefore, the cold energy generated by the refrigerant pipe 13 may be used more effectively.
In the present embodiment, the plate 21 and the body 23 are arranged at an angle of, for example, 90 degrees. The body 23 is arranged on the outside of the ice mold 10, and a lower edge of the body 23 is abutted to a step 521 at the upper edge of one of the two side walls 52 of the bottom cover 50.
Further, a clamping rib 231 is arranged on the inner side (a side facing the ice mold 10) of the body 23. The clamping rib 231 is clamped with an edge protrusion 101 of the ice mold 10, so that the ice baffle 20 is assembled on the ice mold 10, thereby simplifying the assembly operation of the ice baffle 20 and the ice mold 10.
As shown in FIG. 6, the plurality of ice turning teeth on the ice turning bar 12 is in one-to-one correspondence to the plurality of air passage holes 22. That is, the ice turning teeth fall within the air passage holes 22. As the ice turning bar 12 rotates to turn ice, the ice turning teeth can rotate from the air passage holes 22 for ice turning.
As shown in FIGs. 2 to 4, the heat conduction member 15 further includes a plurality of heat dissipation ribs 154 which is spaced apart. The plurality of spaced-apart heat dissipation ribs 154 is located in the airflow cavity 200, and extends from the top wall 151 towards the bottom wall 51 of the bottom cover 50. A guide channel 155 is formed between any adjacent heat dissipation ribs 154. The guide channel 155 is arranged to run through in a direction from one end of the ice mold 10 to the other end of the ice mold 10.
The plurality of guide channels 155 located among the plurality of heat dissipation ribs 154 may be used to guide the cold air in the airflow cavity 200 to circulate as far as possible towards the airflow outlet 202 of the airflow cavity 200, which improves the circulation efficiency of the cold air, and may also assist in increasing the utilization rate of the cold energy generated by the refrigerant pipe 13.
In a preferred embodiment, each guide channel 155 is a straight bar channel, but is not limited to this. In other embodiments of the present invention, depending on different arrangement positions of the heat dissipation ribs, the guide channel may also be a L-shaped channel, a wave-shaped channel, or the like.
As shown in FIGs. 3 and 4, a groove 152 is formed in a side, facing the ice mold 10, of the top wall 151 of the heat conduction member 15. The refrigerant pipe 13 is contained in the groove 152, so that the top wall 151 supports at least part of the wall of the refrigerant pipe 13.
As shown in FIGs. 1, 2, 4 and 5, a water guide member 40 is arranged between the bottom cover 50 and the heat conduction member 15, and is located in the airflow cavity 200.
In a direction of the bottom cover 50 from one end to the other end of the ice mold 10, a first convex edge 54 which protrudes upward is arranged at each of the two ends of the bottom wall 51. In a direction of the water guide member 40 from one end to the other end of the ice mold 10, a second convex edge 44 that protrudes upward is arranged at each of the two ends of the bottom plate 41. The second convex edge 44 is clamped on the inner side of each of the two first convex edges 54, so that the displacement of the water guide member 40 is limited in a first direction.
Moreover, in a direction of the bottom plate 41 from one end to the other end of the ice mold 10, a flange 43 which protrudes upward is arranged at each of the two opposite sides of the bottom plate 41. In a direction of the bottom cover 50 from one end to the other end of the ice mold 10, a side wall 52 which protrudes upward is arranged at each of the two opposite sides of the bottom wall 51. A bump 53 is arranged on the inner side (a side facing the ice mold 10) of each side wall 52. An upper edge of the flange 43 is clamped in a side of the bump 53 close to the bottom wall 51, so that the displacements of the water guide member 40 in a second direction and a third direction are limited. The first direction is perpendicular to the second direction, and the second direction is perpendicular to the third direction. Preferably, the first direction is a left-right direction, the second direction is a vertical direction, and the third direction is a front-rear direction.
That is, the two side walls 52 of the bottom cover 50 and the two first convex edges 54 achieve the accurate positioning of the heat conduction member 40 relative to the bottom cover 50 in the three directions, so that the heat conduction member 40 is positioned more reliably.
The water guide member 40 further includes a water outlet 42. The water outlet 42 is formed in one end of the bottom plate 41 away from the driving mechanism 70, and is located at the rear end of the water guide member 40, i.e., the lowest position of the bottom plate 41 to enable defrosting water to be adequately discharged.
Specifically, the ice-making assembly 100 further includes a heat conduction wire 14, and the heat conduction wire 14 is arranged between the ice mold 10 and the water guide member 40. The bottom plate 41 is provided with a supporting member 45 near the flange 43, and the heat conduction wire 14 is arranged between the top of the supporting member 45 and the ice mold 10. At least part of the heat conduction wire 14 is supported by the top of the supporting member 45, and at least part of the heat conduction wire 14 directly contacts the ice mold 10, so that the heat generated by the heat conduction wire 14 can be transferred to the ice mold 10.
The refrigerant pipe 13 is wrapped by the ice mold 10 and the heat conduction member 15. The heat conduction member 15 will produce frost on the surface inside the airflow cavity 200. As a heating element 14 is started for de-icing, the heat conduction member 15 may also simultaneously absorb heat for defrosting. The defrosting water may flow directly along the surface in the airflow cavity 200 to the bottom plate 41, and is discharged through the water outlet 42. In order to speed up drainage, the bottom plate 41 may be arranged to tilt downward along a direction from one end of the ice mold 10 close to the driving mechanism 70 to the other end of the ice mold 10 at a tilt angle from about 0.5 degree to 2.5 degrees. In addition, the bottom plate 41 is tilted downward from front to back at a tilt angle from about 3 degrees to 5 degrees. Moreover, a second edge 44 at one end of the bottom plate 41 away from the driving mechanism 60 may be regarded as a water retaining edge which can prevent defrosting water (if excessive) from overflowing.
The present invention further provides a refrigerator (not shown). The refrigerator includes a cabinet body, a door body movably connected to the cabinet body, and a refrigeration system. The cabinet body defines a refrigeration compartment. A fan which is used to guide cold air into the refrigeration compartment is also arranged inside the cabinet body. The refrigeration compartment includes a refrigerating chamber and a freezing chamber which are arranged vertically. The door body is used to open and close the refrigerating chamber. The refrigerating chamber or the door body is provided with an ice-making chamber in which the above-mentioned ice-making assembly 100 is arranged. An ice storage box is arranged below the ice-making assembly 100. A distributor which is selectively communicated with the ice-making chamber is arranged on the door body. Ice cubes made by the above-mentioned ice-making assembly fall within the ice storage box for storage, and can be discharged from the distributor.
In the present embodiment, the ice-making chamber is preferably arranged on the door body of the refrigerating chamber. The refrigeration compartment includes the freezing chamber and the refrigerating chamber. Of course, the refrigeration compartment may also include more compartments, such as a variable-temperature chamber.
The refrigeration system includes a compressor and a condenser connected to an outlet side of the compressor. The refrigerant pipe 13 of the ice-making assembly 100 is connected to the refrigeration system. The compressor is arranged at the bottom of the cabinet body. An evaporator used to supply cold energy to the freezing chamber and the refrigerating chamber is arranged behind the freezing chamber. The evaporator may be connected in series with the refrigerant pipe 13 for supply cold energy for ice-making, or connected in parallel to two sides of the compressor and the condenser. Since the ice-making assembly 100 itself is mounted more conveniently, the overall assembly of the refrigerator is also more convenient, thereby reducing the manufacturing cost of the refrigerator.
In summary, the present invention provides the ice-making assembly and the refrigerator, wherein the wind baffle is arranged above the ice mold of the ice-making assembly, and the wind baffle guides cold energy in the airflow cavity below the ice mold to flow towards the ice trays of the ice mold, so as to make full use of cold energy generated by the refrigerant pipe below the ice mold, while avoiding the problems of condensation and frost of an air return pipe arranged at a door body hinge assembly.
