Description

A COOLING APPLIANCE HAVING AN ADJUSTABLE HINGE ASSEMBLY

The present invention relates to a cooling appliance having an adjustable hinge assembly.

In cooling appliances, the door of the cooling appliances, after a prolonged use and due to weight of the food items placed inside the shelves on the door, tends to slack causing a gap to be formed between the door gasket and the body of the cooling appliance. The gap causes the warm air to enter inside the cooling appliance decreasing the energy efficiency of the cooling appliance. Another problem caused by the drop of the door is that the appearance of the cooling appliance deteriorates. Both situations are unfavorable form users’ perspective as they decrease the quality perception and increase energy consumption of the cooling appliance.

A prior art publication in the technical field of the present invention may be referred to as WO2017059909A1 among others, the document disclosing a cooling appliance having an adjustable hinge assembly.

An objective of the present invention is to prevent the misalignment of the door with respect to the body of the cooling appliance in an easily operable manner which allows the users to correct the position of the door without the need to contact service providers which in turn decreases maintenance costs for the users and the cooling appliance manufacturer.

The cooling appliance realized to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a cooling appliance having a body and a door providing access inside the body. The door is pivotable attached onto the body via an adjustable hinge assembly and a corresponding base bracket attached onto the body. The base bracket projects towards the front of the cooling appliance and comprises a counterpart pivot which is pivotably inserted inside the adjustable hinge assembly. The adjustable hinge assembly comprises a housing which houses the operational parts of the adjustable hinge assembly. The housing comprises a pivot into which the counterpart pivot is pivotably inserted. Therefore, the door is pivotably attached onto the body. The housing comprises a first screw and a second screw. The first screw, upon being rotated by the user via a screw driver, moves the door along a first horizontal direction. Likewise, the seconds screw, upon being rotated by the user, moves the door along a second horizontal direction. The first screw actuates the door to move back and forth with respect to the body of the cooling appliance. The seconds screw, on the other hand, actuates the door to move sideways with respect to the body of the cooling appliance. As a result, the alignment of the door is achieved, eliminating the gap caused by the drop of the door. The first screw and the second screw extend parallel to each other. In a preferred embodiment, the first screw and the second screw are adjacent to each other, therefore providing ease of use. Another advantageous effect of the said screws is the fact that the user may easily adjust the position of the door, disposing the necessity of calling the maintenance personnel.

In another embodiment of the present invention, the first screw and the second screw, upon activation by the user, actuates a first adjustment mechanism and a second adjustment mechanism respectively. The said adjustment mechanisms are placed inside the housing and are configured to move along a direction, preferably in the first horizontal direction, parallel to each other.

In another embodiment of the present invention, the first adjustment mechanism comprises the pivot. The counterpart pivot is inserted inside the pivot and upon activation of the first screw, the first adjustment mechanism moves thereby aligning the door along the first horizontal direction.

In another embodiment of the present invention, the adjustable hinge assembly comprises an alignment bed. The alignment bed is placed inside the housing in a slidable manner. The first adjustment mechanism and the second adjustment mechanism are placed inside the alignment bed in a first recess and a second recess. Therefore, a robust adjustable hinge assembly is achieved.

In another embodiment of the present invention, the adjustable hinge assembly comprises an alignment plate placed onto the alignment bed. The alignment plate comprises a first slot and a second slot. The first slot is located above the first recess and the second slot is located above the second recess. The first adjustment mechanism is inserted onto the first recess via the first slot. The second adjustment mechanism is placed onto the alignment bed before the alignment plate is placed onto the alignment bed. The alignment bed further fortifies the structure of the adjustable hinge assembly. Therefore, a robust adjustable hinge assembly is provided.

In another embodiment of the present invention, the second adjustment mechanism comprises a lug projecting upwards and the lug is seated inside the second slot. As a result, a guiding is provided for the second adjustment mechanism.

In another embodiment of the present invention, the extension direction of the second slot forms an acute angle in anti-clockwise direction with the movement direction of the second adjustment mechanism. As a result, as the second adjustment mechanism moves along the second recess, the alignment plate moves along the movement direction of the second adjustment mechanism and at sideways. The change in position depends on the said angle.

In another embodiment of the present invention, the housing is form fittingly placed in a recessed area provided on the door.

In another embodiment of the present invention, the adjustable hinge assembly comprises a cover, covering the operational parts of the adjustable hinge assembly and as a result a robust adjustable hinge assembly is achieved.
