Description

The present invention relates to a cooling appliance, in particular to a cooling appliance having a grain dispenser with a locking mechanism.
High relative humidity is a factor that needs to be taken into account when storing grain and legumes as it adversely affects their shelf life. Humidity increases the possibility of fungal or other bacterial growth on the grain and legumes causing possible health concerns. Apart from micro microbiological infections, it is observed that the average nutritional value loss is directly proportional to the high relative humidity. In regions having high relative humidity, the users are storing their grain and legumes inside cooling appliances to prolong the shelf life. Since the cooling appliances lack necessary storage containers, the users are storing their grain and legumes inside the cooling appliances via jars, and other containers that are mostly hermetically sealed from the inner volume of the cooling appliance. The said storage containers occupy the inner volume of the cooling appliances, decreasing the overall usage volume. Another problem with storing the grain and legumes inside hermetically sealed containers is that the grain and legumes are living organisms and continue their metabolic activities. Meaning that they continue to inhale and exhale and need to be aired every now then to keep their nutritional value high. Apart from this, the grain and legumes release water vapor during their metabolic activities. In the case wherein the users store their grain and legumes in an air tight container and inside the cooling appliances, the water vapor condenses inside the container causes further health issues. Additionally, the users must remove the said jars or containers from the cooling appliance, open them and pour the contents to a secondary and a smaller container to scale the amount before cooking. This is unfavorable from users' perspective as it causes additional work load. As a result, grain dispensing units are provided to users to store their grain or legumes inside the cooling appliances. However, the grain dispensing units, upon being unintentionally activated, causes the grain or legumes to flow inside the cooling appliance which is unfavorable.

The present invention further relates to a cooling appliance comprising a locking mechanism (6) blocking the movement of the chute (5). The container (3) is used as a volume to store granular foodstuff such as the grain and legumes. The dispenser (4) is pivotably attached on a lower portion of the container (3). The dispenser (4) pivots between the closed position and the open position and as the name suggests, during the open position, the grain and legumes are free to flow from the container (3) towards the chute (5) provided on the dispenser (4). Likewise, during the closed position, the grain and legumes are prevented to flow through the dispenser (4) via the chute (5). The lower surface of the container (3) is in conical shape to facilitate the flow of the grain and legumes. The lower most portion of the said conical structure which is an opening for allowing flow of grain is covered by the chute (5) in the closed position. As the dispenser (4) is pressed by means of force applied by a user, the chute (5) moves away from the lower most portion of the said conical structure thus forming a clearance for the grain to flow. The structure of the container (3) and the chute (5) is formed such that the weight of the grain stored inside the container (3) is not sufficient to force the dispenser (4) to the open position. The grain dispensing unit (2) is removably attached onto the inner liner (1). The user may easily remove the grain dispensing unit 2) from the inner liner (1). The chute (5) is provided under the container (3) and is configured to pivot outwards to transmit the grain or legumes stored inside the container (3) as the user presses the dispenser (4). A locking mechanism (8) is provided under the container (3) and behind the chute (5). The locking mechanism (8) allows or blocks the movement of the chute (5). By means of the locking mechanism (8), the users can lock the chute (5) which in turn eliminates the accidental activation of the chute (5) even if the user pushes the dispenser (4). Another advantageous effect provided by means of the locking mechanism (8) is that the locking mechanism (8) only locks the chute (5). Thus, the user may push the dispenser (5) towards the open position without damaging any parts of the locking mechanism (8), chute (5) or the dispenser (3).
The present invention further relates to a cooling appliance wherein the locking mechanism (6) comprises a lug (7) pivotable between a first position during which the lug (7) abuts against and chute (5), locking the movement of the chute (5), and a second position during which the lug (7) moves away from the chute (5), freeing the movement of the chute (5). The locking mechanism (6) comprises the lug (7) wherein the lug (7) is pivotable between said positions. During the position the lug (7) abuts against and chute (5) preventing the pivot movement of the chute (5) if the user presses the dispenser (4). In the case, the user wants to use the grain dispensing unit (2) to obtain the grain or legumes stored therein, the user pivots the lug (7) towards the second position. During the second position, the lug (7) does not contact the chute (5) and the chute (5) is free to pivot outwards if the dispenser (4) is pressed by means of force applied by the user. An advantageous effect provided by means of the lug (7) is that the user may easily pivot it between the said positions, locking and freeing the pivot movement of the chute (5).

As the user pivots the lug (7) towards the first position, the lug (7) becomes seated inside the slot (9) provided as a part of the locking mechanism (8). As a result, the lug (7) is rigidly fixed, eliminating the possibility of accidental pivot of the chute (5).
The present invention further relates to a cooling appliance wherein the locking mechanism (6) comprises a protrusion (10) onto which the lug (7) is seated in the second position, stabilizing the locking mechanism (6) in the second position. By means of the protrusion (10), the lug (7) is rigidly fixed in the second position, eliminating the possibility of the dispenser (4) hitting the lug (7) as the user presses the dispenser (4) in order to receive the grain or legumes stored inside the container (3).
The present invention further relates to a cooling appliance wherein the dispenser (4) is configured to be freely pivotable irrespective of the position of the locking mechanism (6). The dispenser (4) is free to pivot between the open position and the closed position. By means of the free movement of the dispenser (4), the user may force the dispenser (4) towards the open position even if the locking mechanism (8) is in locked position. As a result, accidental breakage of the parts of the grain dispensing unit (2) is prevented.
The present invention further relates to a cooling appliance wherein the dispenser (4) prevents access to the locking mechanism (6) in the open position. The dispenser (4), upon being pivoted towards the open position, almost completely covers the locking mechanism (6) from outside. In such case and if the locking mechanism (6) is in the second position, the grain or legumes freely flows through the chute (5). In the other case, wherein the dispenser (4) is pivoted towards the open position and the locking mechanism (6) is in the first position, grain or legumes are blocked from flowing through the chute (5). By means of the dispenser (4) preventing access to the locking mechanism (6) in the open position, the users, especially children, are prevented to interfere with the locking mechanism (6), preventing accidental flow of the grain or legumes even if the user tries to tamper with the locking mechanism (6).
The present invention further relates to a cooling appliance wherein the chute (5) is attached to the container (3) by a hook (11) and a retainer (12) provided on the chute (5) and the container (3) respectively.
