Abstract
Description
- The present invention relates to a cooling appliance, in particular to a cooling appliance having an ice maker assembly.
- Most of the modern cooling devices are provided with ice maker assembly. The ice maker assembly can be a manual or an automated system configured to freeze water and supply the user with ice. In manual systems, the user needs to rotate the ice mold in order to free ice produced inside the ice mold on regular intervals. The automated systems work similarly with the difference that the ice maker assembly rotates the ice mold on predetermined time intervals in order to free ice produced inside the ice mold. The ice is than stored inside a container located underneath or in close vicinity of the ice mold. A problem with the conventional automatic ice maker assemblies is the fact that the ice stored inside the container tends to stick to each other and form bridges. Another problem is the fact that the ice is sublimated after a long storage time. In order to overcome this, the cold air coming from the evaporator and the fan has to be directed towards the ice container and to the ice mold.
- A prior art publication in the technical field of the present invention may be referred to as
US2014165602A1 among others, the document disclosing a cooling appliance having an ice maker assembly wherein the ice mold is rotatably placed onto the ice maker assembly. - A prior art publication in the technical field of the present invention may be referred to as
US2014165643A1 among others, the document disclosing a cooling appliance having an ice maker assembly wherein the ice mold is rotatably placed onto the ice maker assembly. - A prior art publication in the technical field of the present invention may be referred to as
US2015362242A1 among others, the document disclosing a cooling appliance having an ice maker assembly wherein the rotation of the ice mold is limited by means of a plurality of stoppers. - An objective of the present invention is to provide an ice maker assembly wherein the ice pieces are completely removed from the ice mold which in turn increases the amount of ice delivered to the user.
- Another advantageous effect provided by means of the invention is that the ice pieces are completely removed from the ice mold, thereby eliminating the possibility of overflow of water.
- The method realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims comprises a cooling appliance. The cooling appliance comprises an ice maker assembly. The ice maker assembly comprises a frame and an ice mold rotatably placed onto the frame. The ice mold includes plurality of cavities wherein the water to be frozen is filled. The frame comprises a support member wherein the support member comprises a body, and the body accommodates a first recess provided thereon. A cap is provided and placed onto the body. The cap comprises a second recess and wherein the first recess and the second recess face each other upon placing the cap onto the body such that the first recess and the second recess form a conduit. The ice mold is rotatably supported on the frame by means of a protrusion protruding from the ice mold and seating into the conduit. The protrusion is configured to rotate and slide along the conduit upon rotation of the ice mold. During initial position wherein the ice mold rests on the frame, the protrusion is seated at the lower end of the first recess. Upon rotation of the ice mold, the protrusion moves upwards inside the first recess and therefore inside the conduit and towards the second recess. The width of the first recess and the second recess are different. As a result, as the protrusion passes from the first recess into second recess, two embodiments apply. In the first embodiment, the first recess has a smaller width than the second recess. In the second embodiment, the first recess has a bigger width than the second recess. In both cases, as the protrusion slides from the first recess towards the second recess, the protrusion makes a pulsed motion and hits the second recess and the cap which creates an impact. The impact, vibrates the ice mold which in turn helps the release of ice pieces formed inside the ice mold. By means of this, all ice is successfully removed from the ice mold. An advantageous effect provided by this is that the water overflow is prevented by removing all ice pieces from the ice mold. This may otherwise cause the water to cover the ice mold and the frame which will subsequently freeze, causing malfunction of the ice maker assembly.
- In an embodiment of the invention, the conduit comprises a stepped part where the first recess and the second recess adjoin. In the first case, wherein the first recess has a smaller width than the second recess, the side walls of the second recess forms the stepped part. As the ice mold is rotated, the protrusion moves along the first recess and abuts against the side walls of the second recess. After a certain rotation angle of the ice mold, the protrusion jumps over the stepped part and hits the cap. As a result of which an impact occurs. This helps release the ice pieces from the ice mold. In the second case, wherein the first recess has a bigger width than the second recess, the protrusion simply falls from the first recess into the second recess which creates the impact. This helps release the ice pieces from the ice mold. By means of the stepped part, the ice pieces are efficiently removed from the ice mold which helps reduce the aforementioned problems.
- In an embodiment of the invention, the ice mold extends along a direction and the conduit extends in another direction, wherein the extension direction of the conduit is inclined with respect to the extension direction of the ice mold. The inclination facilitates the protrusion to rotate and slide from the first recess towards the second recess.
- In an embodiment of the invention, the conduit is in oval form. The shape of the conduit facilitates the movement of the protrusion along the conduit.
- In an embodiment of the invention, the protrusion is produced integrally with the ice mold. This helps increase the life time of the ice mold and the protrusion.
- In an embodiment of the invention, the ice mold is rotated by means of a motor provided on the frame. This applies to automatic ice maker assemblies.
- In another embodiment of the invention, the ice mold is rotated by means of a lever provided in close vicinity of the ice maker assembly. This applies to manual ice maker assemblies.
- In another embodiment of the invention, the body comprises a fixing means onto which the cap is placed and fixed on the body. The fixing means provides a rigid assembly.
- In another embodiment of the invention, the body is produced as an integral part of the frame.
- In another embodiment of the invention, the body is placed onto the frame by means of a recess provided thereon. The recess is configured to match the shape pf the body such that the relative motion of the body with respect to the frame is prevented.
- By means of the present invention, the ice maker assembly releases all the ice pieces formed inside the ice mold upon its rotation. As a result of which, ice production capacity of the ice maker assembly is improved, meanwhile eliminating the possibility of water overflows.
- The drawings are not meant to delimit the scope of protection as identified in the claims nor should they be referred to alone in an effort to interpret the scope identified in the claims without recourse to the technical disclosure in the description of the present invention.

- In the preferred embodiment of the invention, the width of the first recess (5) and the second recess (7) are different. The ice maker assembly (1) of the cooling appliance comprises the frame (2) onto which the ice mold (9) is rotatably placed. The frame (2) further comprises the support member (3) wherein the support member (3) comprises the body (4) and the cap (6). The body (4) and the cap (6) each comprises the first recess (5) and the second recess (7) respectively. The said recesses (5,7) are configured to face each other, upon placing the cap (6) onto the body (4) and defines the conduit (8). The ice mold (9) comprises cavities wherein the water to be frozen is filled. The ice mold (9) has an elongated form and extends along a direction. The ice mold (9) further comprises the protrusion (10) via which the ice mold (9) is rotatably placed onto the frame (2). The protrusion (10) moves inside the conduit (8) upon rotation of the ice mold (9). The protrusion (10) makes a rotational and sliding movement inside the conduit (8) and moves towards the cap (6). First of all, the protrusion (10) moves along the first recess (5) and then passes to the second recess (7). The first recess (5) and the second recess (7) have different widths. Therefore, as the protrusion (10) passes from the first recess (5) to the second recess (7), two possibilities exist. In the first case, wherein the width of the first recess (5) is greater than the second recess (7), the protrusion (10) abuts against the side walls of the second recess (7). Afterwards, the protrusion (10) rotates around the side walls of the second recess (7) and falls into the second recess (7), the impact of which releases ice pieces formed inside the ice mold (9). In the second case, wherein the width of the second recess (7) is greater than the first recess (5), the protrusion falls into the second recess (7), the impact of which releases ice pieces formed inside the ice mold (9). By means of the said recesses (5,7) having different widths, all the ice formed inside the ice mold (9) is removed from the ice mold (9) by the vibration of the impact. Another advantageous effect is that the water overflow from the ice mold (9) due to remaining ice pieces is prevented.
- In the preferred embodiment of the invention, the conduit (8) comprises a stepped part formed by convergence of the first recess (5) and the second recess (7) and that the protrusion (10) is configured to impact the cap (6) by jumping over the stepped part of the conduit (8) upon rotation of the ice mold (9) to facilitate the release of the ice pieces.
- In the preferred embodiment of the invention, the extension direction of the conduit (8) is inclined with respect to the extension direction of the ice mold (9). The ice pieces are released upon rotation of the ice mold (9) and during release, the ice mold (9) faces sideways. By providing the conduit (8) inclined, the impact direction of the protrusion (10) will be perpendicular to the extension direction of the ice mold (9) during release of ice pieces. This helps improve the efficiency of the impact and therefore that of the ice releasing process.
- In the preferred embodiment of the invention, the conduit (8) is in oval shape. The oval shape helps the protrusion (10) to reach the second recess (7) easier, thereby improving the efficiency of the ice release.
- In the preferred embodiment of the invention, the protrusion (10) is integral with the ice mold (9). By providing the protrusion (10) integral with the ice mold (9) helps increase structural strength of the ice maker assembly (2). Another advantageous effect is that the vibration caused by the impact is transferred to the ice mold (9) at a higher rate.
- In the preferred embodiment of the invention, the ice mold (9) is rotated by means of a motor provided on the frame (2). The motor is provided on the frame (2) and is configured to rotate the ice mold (9). This particular embodiment is especially advantageous to be used at automatic ice making assemblies.
