Description

Technical Field

The present invention relates to cooling devices comprising a vacuum device for vacuuming containers closed with a lid, such as bottles or jars.

Background of the Invention

Various applications are provided in the known art for long-term storage of food products without spoiling. For example, foods can be stored directly in a cooling device, stored as a canned food or stored by freezing in a freezing compartment. However, each storage application may have various handicaps that do not meet user's expectations. For example, if the food is not desired to be stored for a very long time, storage by freezing will not be effective in this case.
One of the applications enabling foods to be stored for a long time without spoiling is to store a food placed in a container, which has a lid closed or opened preferably by turning, in a vacuum environment by evacuating air in the container. In this application, one can easily access food when needed, and the food can be stored in a healthy way for a long time as contact of food with air is prevented. For that reason, this application storing the food in a vacuum environment is commonly preferred by users.
In order to store food in a container in which air is vacuumed, air inside the container should be evacuated after placement of food therein, and inner side of the container should be isolated from outer environment. Various vacuum devices are provided in the known art for such a process. However, these devices occupy extra volume since they are external devices, as well as creating extra costs for users. Vacuum devices can be integrated into various household appliances for solving said problem. An example of such an application is disclosed in the published patent document US5271240A . The application disclosed in said document provides a refrigerator containing a vacuum device. However, in such applications, vacuum device imposes some usage limitations for the user as it allows the container with a specific lid to be vacuumed.

Description of the Invention

Various applications are provided for long-term storage of food products without spoiling, wherein one of these applications is to place a food in a container, vacuum the container and store the food in a vacuum environment. For such storage applications with vacuuming, air inside the container in which food is placed should be evacuated with a vacuum device. Various vacuum devices are provided in the known art for such a process. However, these devices occupy extra space since they are external devices, as well as creating extra costs for users. In order to avoid this, household appliances with vacuum devices have been proposed. However, such applications covered by the known art requires usage of containers with a specific lid for vacuuming, which prevents user from performing vacuuming process easily whenever she/he needs it and also creates an extra cost for the user. Within this context, a cooling device comprising a vacuum device is provided according to the present invention for solving said problems.
The cooling device (e.g. a refrigerator) according to the present invention, as illustrated in figures 1-13, comprises at least one storage compartment (e.g. a cooling compartment and/or freezing compartment) in which products to be stored at a certain temperature are placed; at least one door (D) controlling access into said storage compartment; and at least one vacuum device (V) for vacuuming containers with a first lid (K2) closed or opened preferably by turning, such as bottles or jars (K). The vacuum device (V), as illustrated in figures 3-7, comprises at least one main body (1) in which vacuuming process is performed, which is preferably in the form of a box open on opposite sides (one of these open sides forming the first opening), and comprises:

at least a first compartment (1a) suitable for receiving, for vacuuming process, the first lid (K2) of the container to be vacuumed and preferably at least a part (especially the part close to the first lid K2)) of the body (K1) thereof;
at least a first opening preferably having a circular form for placing the first lid (K2) and preferably at least a part of the body (K1) into the first compartment (1a) (i.e. for connecting the container to the first compartment (1a));
at least a second compartment (1b) adjacent to the first compartment (1a) (the second compartment (1b) preferably being located at an upper part of the first compartment (1a), and the first opening being located at a lower part of the first compartment (1a));
at least one partition wall (1c) that hermetically separates the first compartment (1a) and the second compartment (1b);

In an exemplary embodiment of the invention, if the user needs a vacuuming process, she/he places the container, e.g. an ordinary jar (K), such that the first lid (K2) is aligned with first opening of the vacuum device (V) provided in the cooling device (the vacuum device (V) may be provided at any part of the cooling device), as illustrated in Figure 8. The container is then moved towards the first compartment (1a) such that the first lid (K2) passes through the first opening and enters into the first compartment (1a), as shown in Figure 9. As a result of such a movement, the insulation element (4) fits into the first lid (K2) or at least a part of the body (K1) so as to surround them (i.e. such that the first lid (K2) or the body (K1) crush the insulation element (4)), depending on dimensions of the container (e.g. if a surface area of the first lid (K2) is less than a surface area of the cross-section of the body (K1), the insulation element (4) can fit into the body (K1), and if a surface area of the first lid (K2) is close to or equal to a surface area of the cross-section of the body (K1), the insulation element (4) can fit into the first lid (K2)). Therefore, the first opening is closed by body of the container, thus preventing air intake into the first compartment (1a) from outer environment. After the first compartment (1a) is disconnected from outer environment, vacuum pump (5) is activated by trigger mechanism (3) and air inside the first compartment (1a) is evacuated, as illustrated in Figure 10. While air inside the first compartment (1a) is evacuated, it is also ensured that air inside the container is evacuated through gaps between the body (K1) and the first lid (K2), which is not tightly sealed to the body (K1). When pressure value reaches a predetermined value, operation of vacuum pump (5) is stopped, and the closed valve (7) is opened to fill the first compartment (1a) with air instantly. Since air is filled into the first compartment (1a) in a quite short time, a pressure difference occurs between the first compartment (1a) and the inside of the container, and this pressure difference causes a force to be applied on the first lid such that gaps between the first lid (K2) and the body (K1) are closed as illustrated in Figure 11. Said gap is closed by the effect of said force, both by flexion of first lid (K2) towards the body (K1) and by the force creating a compression movement by rotating the first lid (K2) on the body (K1). Evacuated container is isolated from outer environment when the first lid (K2) is tightly sealed to the body (K1), and vacuum process is completed when the container leaves the first compartment (1a) as illustrated in Figure 12. Thanks to the cooling device according to the present invention, need for using an external device that occupies extra space for vacuuming process can be minimized, and food can be stored under vacuum, for example in a standard jar (K), without requiring containers with specific lids to store the food under vacuum.
In a preferred embodiment of the invention, the trigger mechanism (3) may be at least one sensor (e.g. a proximity sensor, a light sensor, a laser distance sensor, an ultrasonic sensor etc.) detecting placement of first lid (K2) into the first compartment (1a) (i.e. detecting connection of container to the first compartment (1a)) and enabling the vacuum pump (5) to be activated based on this detection. Therefore, the vacuuming process can be initiated automatically when the container is placed in the vacuum device (V)).
In another embodiment illustrated in drawings, the trigger mechanism (3) comprises at least one trigger switch (8) (e.g. a paddle switch) in connection with the vacuum pump (5); and at least one trigger member (3b) having a first position in which the trigger member (3b) contacts the trigger switch (8) to activate it and a second position in which the trigger member (3b) does not contact the trigger switch (8). The trigger member (3b) is preferably connected with the main body (1) such that at least a part thereof can be moved towards or away from the trigger switch (8) by the user (this movement is preferably a rotational movement around an axis) and that the trigger member (3b) is brought into the first position or the second position by means of this movement. Thus, initiation of the vacuuming process can be carried out under control of the user and a faulty vacuuming process can be prevented. In this embodiment, the trigger mechanism (3) also preferably comprises at least one carrying member (3a), preferably having a "U" form, which is connected to the main body (1) (preferably provided at an upper part of the main body (1)), comprises at least a first movement opening, wherein the trigger switch (8) is located on the carrying member (3a) preferably between the main body (1) and the carrying member (3a), and the trigger member (3b) is connected to the carrying member (3a) to move in the first movement opening and close the first movement opening. In this embodiment, preferably, an opening is provided at one side of the second compartment (1b) (preferably at a side thereof opposite to the adjacent side with the first compartment (1a)), wherein the carrying member (3a) and the trigger member (3b) together function as a cover that covers said opening. In this embodiment, there is also preferably at least one channel inside the carrying member (3a), which preferably extends along the carrying member (3a), wherein at least one lighting element (3f) is provided in said channel. Stages of the vacuuming process can be notified to the user in various colours via the lighting element (3f). Trigger mechanism (3) also preferably comprises at least one luminaire (3d) located on the carrying member (3a) to cover open portion of the channel. Thus, light emitted by the lighting element (3f) can be emitted more homogeneously and softly to the environment. In this embodiment, the trigger mechanism (3) also preferably comprises at least a second lid (3c) preferably having a "U" form, located to surround the carrying member (3a) and the luminaire (3d), comprising at least a second movement opening, wherein the trigger member (3b) is connected to the carrying member (3a) to move in the second movement opening and cover the second movement opening. In this way, lighting element (3f) and luminaire (3d) are protected from external factors, while elements such as screws that provide the assembly can be prevented from being visible from outside, and visual integrity with the main body (1) can be provided. The trigger mechanism (3) also preferably comprises at least two mounting holes (3e) corresponding to each other, wherein at least one of them is located in the carrying member (3a) and at least one in the trigger member (3b) for connecting the trigger member (3b) movably to the carrying member (3a); and at least one shaft (10) for connecting the trigger member (3b) to the carrying member (3a) by passing through the mounting holes (3e). Therefore, trigger member (3b) can rotate in the axis of the shaft (10) and can be brought into the first position or second position.
In another exemplary embodiment, the vacuum device (V) according to the invention preferably comprises at least one holding member (1g) located to at least partially surround the first opening, having the form of a protrusion extending from the main body (1), supporting the insulation element (4) from its outer side so that the insulation element (4) is located between the holding member (1g) and the main body (1), and thus, supporting the insulation element (4) which can flex while the container is connected to the first compartment (1a).
In another preferred embodiment, the vacuum device (V) comprises at least one placement body (2) in connection with a side of the main body (1) where the first opening is provided, supporting the container for connecting the container to the first compartment (1a) properly, and having at least one placement aperture (2a) through which the first lid (K2) passes to align with the first opening and at least a second opening (2c) matching with the first opening and preferably having a circular form. Said placement body (2) preferably comprises at least two guiding members (2b) opposite to each other, which extend preferably along the placement aperture (2a) away from the second opening (2c) on two opposite sides of the placement aperture (2a). In this embodiment, when the container is to be attached to the vacuum device (V) for vacuuming process, the first lid (K2) is placed in the placement aperture (2a) and the first lid (K2) is guided by the guiding members (2b) so that container is moved towards the second opening (2c). When the first lid (K2) matches with second opening (2c), the container is moved towards the first compartment (1a) for vacuuming process, and the first lid (K2) is located in the first compartment (1a) by passing through the second opening (2c) and the first opening. Thus, container is moved by being supported and the ease of use is provided, and the vacuuming process can be performed properly by ensuring the correct alignment of the container. In this embodiment, there is also preferably at least one placement surface (2d) located in the second opening (2c), extending from the placement body (2) towards centre of the second opening (2c), wherein at least one part of the insulation element (4) is placed on the placement surface (2d) such that it is between the placement body (2) (or itself) and the main body (1), and preferably width of the part of the placement surface (2d) that extends from the placement body (2) towards the centre of the second opening (2c) can be changed for changing width of the second opening (2c). In this embodiment, placement body (2) also preferably comprises at least one connection surface (2e) extending from the placement body (2) towards the cooling device (or the door (D)) for connection of the vacuum device (V) to the cooling device (preferably to the door (D) of the cooling device). In this embodiment, the vacuum device (V) preferably comprises at least one connection apparatus (11) which is fitted on the connection surface (2e) and connected from one side to the cooling device (preferably to an inner surface (D1) of the door (D) facing the storage compartment of the cooling device when in the closed position) and from another side to the main body (1). Therefore, the vacuum device (V) can be attached to the cooling device in a removable manner. In another preferred embodiment, the vacuum device (V) further comprises at least one holding member (1g) located in the main body (1) to at least partially surround the first opening and to extend towards the placement body (2), placed in the second opening (2c) for connection of the placement body (2) to the main body (1), supporting the insulation element (4) from its outer side so that the insulation element (4) is settled between the holding member (1g) and the placement surface (2d).

Therefore, containers of different sizes can also be subjected to the vacuuming process by ensuring that the insulation element (4) and the placement body (2) having a second opening (2c) that has a suitable width for the width of the container to be vacuumed are attached to the main body (1). In this embodiment, alternatively, as illustrated in Figure 13, the placement body (2) preferably comprises at least one fixed part (2f) which is fixed to the main body (1); and at least one movable part (2h) which is movable with respect to the main body (1) so as to move towards or away from the fixed part (2f), forms the placement body (2) when it is engaged with the fixed part (2f), and on which the placement aperture (2a) is provided. In this embodiment, the insulation element (4) is preferably located on the placement body (2) and consists of at least two parts, one part on the fixed part (2f) and the other part on the movable part (2h).

In another embodiment of the cooling device according to the invention, the vacuum device (V) preferably comprises at least one closing mechanism which enables the first lid (K2) to be compressed by an external force after completion of the vacuuming process. Said closing mechanism rotates by grasping the first lid (K2), and thus, enables the first lid (K2) to be tightly connected to the body (K1) by rotating. Rotational movement of the closing mechanism may be controlled by the user manually or it may also be performed automatically when it is detected that the predetermined vacuum value is reached by means of at least one movement element, which can be a motor. In this embodiment, in order to perform lid closing process, the vacuum device (V) may also preferably comprise at least one alerting element which alerts the user audibly and/or visually when the vacuuming process is completed.
In another alternative embodiment, the insulation element (4) is preferably a gasket inflatable by at least one fluid (e.g. air).

In another preferred embodiment, the vacuum device (V) comprises at least one movement mechanism for moving the container whose first lid (K2) matches with the first opening towards the first compartment (1a) and/or for moving the container in connection with the first compartment (1a) away from the first compartment (1a) after completion of the vacuuming process. In an embodiment, the movement mechanism preferably comprises at least one conveyor system which is located at the main body (1), lifts the container towards the first compartment (1a) and/or lowers the container away from the first compartment (1a). Yet in another embodiment, the movement mechanism comprises at least one electromagnet which is located in the main body (1) and which, when energised, applies a force on the first lid (1a) made of metal so that the container is pulled towards the first compartment (1a), and preferably applies said pulling force on the container during vacuuming process such that the first lid (K2) or the body (K1) crush the insulation element (4) and thus a reliable vacuum environment is created between the first compartment (1a) and the container, wherein the electromagnet stops applying a force on the first lid (K2) when it is de-energised.
Yet in another embodiment, the cooling device preferably comprises at least one tube preferably located at the cooling device or the vacuum device (V) and containing at least one gas which prevents food from spoiling and comprises at least one substance that does not react or prevents bacterial-fungal growth; and at least one low-flow valve located at the vacuum device (V) and enabling said gas to be transferred into the container from said tube. In this embodiment, when vacuuming of the container is completed (i.e. when the predetermined pressure value is reached), the low-flow valve is opened and the gas in the tube is filled into the first compartment (1a) before opening the valve (7) and sending air into the first compartment (1a) instantly. As the gas flow supplied from the tube into the first compartment (1a) is slow, the gas filled into the first compartment (1a) does not create a pressing force on the first lid (K2), and therefore gaps between the first lid (K2) and the body (K1) are not closed. Thus, the gas filled in the first compartment (1a) can pass into the container through these gaps. After the predetermined amount of gas is filled into the container, the low-flow valve is closed and the gas flow from the tube to the first compartment (1a) is cut off. Then, vacuuming process continues normally by opening the valve (7). In another embodiment, after all the air in the container is vacuumed, the low-flow valve is opened to fill the container with the gas coming from the tube, and this filling process continues until a pressure of the gas filled into the container is equal to the external environment pressure. Then, the first lid (K2) is compressed by at least one closing mechanism, so that the first lid (K2) can firmly grasp the body (K1). In this embodiment, the vacuum device (V) may preferably comprise at least one sensor (e.g. a pressure sensor) for detecting an amount of gas filled into the container. The tube may be located, for example, in any area of the cooling device, and gas in the tube can be transferred to the container, for example through the first compartment (1a), via various transmission lines such as pipes. Said tube may be a tube externally attached by the user to the cooling device (e.g. door (D) of the cooling device) or vacuum device (V).
In another embodiment, the vacuum device (V) preferably comprises at least one vacuum slot in the form of a recess from the first compartment (1a) towards the second compartment (1b), which is located at the partition wall (1c) at an area where the vacuum pump (5) and the valve (7) are connected to the first compartment (1a). Thanks to the vacuum slot, parts of narrow necked containers, such as bottles, where the first lids (K2) thereof are provided can be placed in the vacuum slot, and the insulation element (4) can also be fitted to the container body (K1), enabling the narrow necked containers to be effectively vacuumed.
Thanks to the cooling device according to the present invention, containers such as bottles or jars (K), which are either customized for vacuuming or standard, can be vacuumed easily, practically and effectively without need for a device that occupies extra space.
