DETAILED DESCRIPTION
The present invention is described in detail in the following with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention. All structural, methodological and functional changes made by persons of ordinary skill in the art according to these embodiments should fall within the protection scope of the present invention.
FIG. 1 illustrates a specific embodiment of a cooling appliance according to the present invention. In this embodiment, the cooling appliance 100 includes: a heat insulation cabinet 10, in which a storage chamber (not shown) is formed; and a door 11, including, in this embodiment, a pair of double doors that is pivotally installed on the heat insulation cabinet 10 through hinges (not shown), cooperating with the heat insulation cabinet 10 to selectively open or close the storage chamber. As a conventional cooling appliance, the storage chamber in this embodiment may also include a freezing chamber and a refrigerating chamber. The cooling appliance 100 further includes a dispenser system 20, where the dispenser system 20 may be used for allocating liquid (such as water) and ice in an ice storage container (not shown) of the cooling appliance 100 to a dispenser cavity 21. In this embodiment, the dispenser cavity 21 is formed by recessing an outer surface of the door 11 inwards.
FIG. 2 is a sectional view of a dispenser system installed in the door of the cooling appliance according to the present invention. Referring to FIG. 2, the dispenser system 20 includes an ice delivery path P from the ice storage container to the dispenser cavity 21. The ice delivery path P includes an ice outlet 33 located on a terminal of the path and disposed above the dispenser cavity 21. Ice (such as an ice block or trash ice) is discharged into a receiving container located in the dispenser cavity 21 through the ice outlet 33. In this embodiment, the ice delivery path P includes an ice channel 40 passing through the door 11. The ice is discharged from an outlet 41 of the ice channel 40 and moves towards the ice outlet 33. The outlet 41 may be selectively opened or closed by a closing component (not shown).
The dispenser system generally further includes a water delivery channel (not shown), used for allocating drinking water stored in the cooling appliance to the dispenser cavity 21. An dispenser mechanism of ice and water is known by persons of ordinary skill in the art, and the details are not described herein again. Referring to FIG. 3 to FIG. 10, the dispenser system 20 further has a splash-proof component 30 disposed close to the outlet 41 of the ice channel 40. In this embodiment, the splash-proof component 30 is installed inside the door through an installation frame 23, used for ice discharged from the outlet 41 to pass through, and leading the ice to a container placed in the dispenser cavity 21. In this embodiment, the splash-proof component 30 includes an installation part and a buffering part. The buffering part is approximately in an inverted cone shape. Such a shape is capable of restricting ice from spreading and splashing around after being discharged, so that the ice can enter the container (not shown) in the dispenser cavity 21 more accurately. The buffering part has a circular ice outlet 33 located at the bottom and used for ice to pass through to enter the dispenser cavity 21, and an ice inlet 22 at the top and more close to the outlet 41 of the ice channel 40. The installation part is a circular ring formed by a top portion of the buffering part radially extending outwards, and is connected to the installation frame 23 through a post- forming process. It should be understood that, the installation part of the splash-proof component 30 may be connected to the installation frame 23 through other known connection methods such as adhesives and pressing.
In this embodiment, the splash-proof component 30 is made of a resilient material. Compared with a splash-proof component 30 in the prior art that is generally made of a rigid material, the splash-proof component 30 herein absorbs a part of or even all kinetic energy of ice when ice hits the splash-proof component 30, thereby avoiding irregular splashing of the ice as much as possible, so that the ice slows down to pass through the ice outlet 33 and enters the dispenser cavity 21. In other embodiments, it is feasible that only the buffering part of the splash-proof component 30 is made of a resilient material, and the installation part is made of another material. The resilient material may include a flexible material, a deformable material, or any material that help better absorption of kinetic energy of ice, such as synthetic rubber, preferably, silicon rubber, polyvinyl chloride (PVC) rubber, neoprene rubber, or a combination thereof. It should be understood that, in a replacement embodiment, the splash-proof component 30 may be made of another material. For example, the deformable buffering part (that is, several elastic sheets, elaborated in the following) may also be made of sheet metal or plastic tabs/films easy to be bent.
Referring to FIG. 3 to FIG. 6, in this embodiment, the ice outlet 33 of the splash-proof component 30 is expandable. Compared with a fixed opening in the prior art, a smaller initial radial size may be set for the ice outlet 33, so that the buffering part 31 of the splash-proof component 30 can also effectively buffer smaller-sized ice.
In this embodiment, a slit 31 is disposed on the buffering part of the splash-proof component 30. The slit 31 extends from the ice outlet 33 to the installation part, without passing through the installation part. Preferably, an extension line of the slit 31 passes through the center of the splash-proof component 30. Persons skilled in the art may easily think of that, an initial radial size of the ice outlet 33 may be 0. That is, in this case, the slit 31 passes through the center of the splash-proof component 30. At least one slit 31 is disposed on the splash-proof component 30. As a preferred embodiment, the number of the slits may be 3 or 4, equally dividing the buffering part into several elastic sheets 32.
The dispenser system is further disposed with a water outlet 50, in communication with a liquid delivery channel (not shown), to allocate liquid into the dispenser cavity 21.
Referring to FIG. 7 and FIG. 8, in this embodiment, the ice inlet 22 of the splash-proof component 30 has a first radial size Φ1, and the ice outlet 33 of the splash-proof component 30 has an initial radial size Φ2 and an expansion radial size Φ3. As mentioned above, since the ice outlet 33 is expandable, the initial radial size Φ2 of the opening may be set to be relatively small. For example, a ratio of the initial radial size Φ2 to the first radial size Φ1 is less than or equal to 1/2, preferably, between 1/3 and 3/8. In this embodiment, the initial radial size Φ2 of the ice outlet 33 is less than or equal to 22 mm, such as 22 mm; and the first radial size Φ1 is 62 mm.
Referring to FIG. 9 and FIG. 10, one end of the slit 31 is closed and the other end is open, and a cut angle ang is formed at the closed end.
In this embodiment, when ice enters from the ice inlet 22 of the splash-proof component 30 and then is discharged through the ice outlet 33, each elastic sheet 32 of the buffering part is bent and deformed due to an ice impact, and a distance between the adjacent elastic sheets becomes larger. In this case, an opening formed at a bottom of each elastic sheet 32 expands, so that the value of the expansion radial size Φ3 may reach up to 60 mm; the cut angle ang becomes larger because the distance between the adjacent elastic sheets becomes larger. Since the buffering part is made of a resilient material, when ice passes through the ice outlet 33, each elastic sheet 32 of the buffering part restores to an original state. Correspondingly, the size of the ice outlet 33 restores to the initial radial size Φ2, and the cut angle ang also restores to an original angle. In this embodiment, the cut angle is set to 0 when no ice passes through.
An angle between a surface defined by the outlet 41 of the ice channel 40 and a surface defined by the ice inlet 22 of the splash-proof component 30 is an acute angle, which ensures that under the action of inertia, ice smoothly enters the ice inlet 22 of the splash-proof component 30 at a relatively accurate angle.
As mentioned above, in the prior art, to minimize the possibility of ice splashing when ice passes through the splash-proof component 30, a smaller ice outlet 33 may be disposed. Preferably, the several elastic sheets (that is, the buffering part) forming the ice outlet 33 are made of a resilient material, and therefore are expandable. Then the splash-proof component 30 can properly adjust the size of the ice outlet 33 according to the size of ice passing through and the amount of ice passing through in a unit time, to achieve a relatively desirable dispenser rate.
Referring to FIG. 7, FIG. 8 and FIG. 11, the overall splash-proof component 30 may generally be set to a shape that gradually narrows from top to bottom. In this embodiment, the splash-proof component 30 is preferably set to an inverted cone shape. Since the splash-proof component 30 is disposed in the dispenser cavity 21, the disposition of the inverted cone shape not only implements the foregoing substantial functions, but also fulfills aesthetic needs of people.
In the foregoing embodiments, the ice outlet 33 is jointly restricted by lower edges of the elastic sheets 32. However, in a replacement embodiment, several deformable elastic sheets may be directly disposed in the ice outlet 33 to directly form the buffering part. When ice passes through the ice outlet, the elastic sheets are deformed to expand/open the ice outlet and absorb at least one part of kinetic energy of ice, and the ice falls into the receiving container through the expanded ice outlet. The advantage of using the elastic sheets located in the ice outlet to directly form the splash-proof component lies in that, by directly disposing the ice outlet on an upper wall of the dispenser cavity, the splash-proof component obviously extending into the dispenser cavity shown in FIG. 3 to FIG. 6 may be saved. The cooling appliance 100 adopts the dispenser system 20 described in the foregoing embodiments, and can allocate ice and liquid without opening the door of the cooling appliance, which is convenient for use. In addition, the splash-proof component 30 is disposed, which can effectively reduce overhigh kinetic energy of ice due to inertia of ice to prevent the ice from spreading and splashing, and accurately and safely allocate ice of different sizes and of different flows into the container in the dispenser cavity 21. Moreover, the dispenser system 20 is embedded in the door 11, which does not bring any redundant volume to refrigerators, thereby being practical and convenient.
For persons skilled in the art, obviously, the present invention is not limited to the foregoing details of exemplary embodiments, and can be implemented through other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, seen from whichever point, the embodiments should be construed as exemplary, but not restrictive. The scope of the present invention is subject to the appended claims but not the foregoing description. Therefore, all changes falling within the meanings and scope of the equivalent requirements of the claims should be included in the preset invention. Any mark of the accompanying drawings in the claims should not be regarded as limitation to the related claims.
Besides, it should be understood that, although the specification is described according to the embodiments, each embodiment does not include merely one independent technical solution. The narration mode of the specification is for the sake of clarity. Persons skilled in the art should regard the specification as a whole. The technical solutions of the embodiments may be properly combined, to form other embodiments that may be understood by persons skilled in the art.
