SPECIFICATION

A COOLING DEVICE

TECHNICAL FIELD

The invention relates to a cooling device having a body, at least one door connected to said body in an openable manner, at least one gasket configured to be connected to said door from one side and to be adhered to a frame from the other side by means of magnetic force in order to provide sealing between the body and the door when the door is closed, and at least one gasket holder coupled to the door from one side.

KNOWN STATE OF THE ART

Cooling devices are devices which operate with a specific cycle and which keep foods and beverages cool and which preserve foods and beverages for a long time. By means of their cycles, cooling devices suction hot air existing in the inner medium and transfer said hot air to the outer medium. It is known that keeping foods in a cool medium decelerates deterioration of foods. Domestic type coolers are known as refrigerators in the present art. Refrigerators have a closed chamber and a cover for reaching the closed chamber. In order to provide thermal isolation between the cover and the chamber, gasket is used whose thermal isolation is strong.

Gaskets used in refrigerators are made of flexible material. Preferably gaskets show magnetic characteristic and they adhere to the periphery of the refrigerator and prevent the cool air, existing in the chamber, from exiting outside. In the present art, one of the typical problems faced in refrigerators is that the cover is forced to be opened in a repetitive manner at short time intervals. When the cover is first opened, the hot air existing in the outer medium displaces with the cool air existing inside the chamber. After this displacement, the cover of the refrigerator is closed and the hot air, entering into the chamber, is cooled and shrank. The shrinking of the air makes vacuum effect inside the chamber and the second time opening of the cover becomes difficult.

The patent KR20000034210 known in the literature provides a mechanism for opening a refrigerator door easily. Accordingly, a negative pressure occurs in the body as the door of the refrigerator is closed. This makes opening of the refrigerator door difficult. The invention relates to an embodiment for eliminating this problem. BRIEF DESCRIPTION OF THE INVENTION

The object of the invention is to eliminate the pressure difference between the outside of the body and the inside of the body while the door of the cooling device is being opened.

The present invention is a cooling device having a body, at least one door connected to said body in an openable manner, at least one gasket configured to be connected to said door from one side and configured to be adhered to a frame from the other side by means of magnetic force in order to provide sealing between the body and the door when the door is closed, and at least one gasket holder coupled to the door from one side.. Accordingly, the cooling device comprises at least one elastic element provided between the door and the side of the gasket holder which is coupled to the door. Thus, while the door is closed or while the door is being opened, the adhesion region is separated from the frame and the air pressure existing inside the body and existing outside are balanced.

In a probable embodiment of the invention, the gasket holder is coupled to the door from one side and placed into a channel provided on the gasket from a holding end provided on the other side.

In a probable embodiment of the invention, the elastic element is provided between the gasket holder and a press plate connected to the door. Thus, the press plate is fixed during the movement of the gasket holder with respect to the frame.

In a probable embodiment of the invention, the elastic element is a helical spring and comprises at least one guide pin which extends through the elastic element and connected to the gasket holder from one end and which passes through at least one movement channel provided on the press plate from the other end. Thus, the spring is encircled around the guide element and moves linearly in the axis of the guide element.

In a probable embodiment of the invention, the guide pin comprises at least one fixation element which passes through the movement channel and provided on the side of the elastic element which is opposite with respect to the press plate. Thus, the removal of the guide element from the movement channel is prevented.

In a probable embodiment of the invention, at least one step, configured to rest onto the press plate when the elastic element is compressed at an amount which is equal to a predetermined gap distance, is provided on the guide pin. Thus, the guide element is rested onto the press plate and the door is pushed by the pusher.

In a probable embodiment of the invention, at least one door opening assistant which has at least one pusher is provided. Thus, the gasket holder is removed from the body and the adhesion region is separated from the frame.

In a probable embodiment of the invention, at least one control unit which is associated with the door opening assistant is provided. Thus, in the door opening assistant, the pusher makes linear movement at predetermined time intervals.

In a probable embodiment of the invention, the control unit is configured to activate the door opening assistant at the end of a predetermined duration when the door is closed and to provide pushing of the gasket holder towards the elastic element. Thus, while the door is being opened, the pressure existing inside the body and existing outside the body are balanced.

In a probable embodiment of the invention, the control unit is configured to activate the door opening assistant at predetermined intervals when the door is closed and to provide pushing of the gasket holder towards the elastic element. Thus, while the door is closed, the pressure difference existing inside the body and existing outside are eliminated at specific time intervals.

In this detailed description, the subject matter cooling device (10) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

With reference to Fig. 1 , the subject matter cooling device (10) comprises at least one body (70), wherein the items to be cooled are stored, and at least one door (20) which provides access into the body (70) in order to put or remove the items, desired to be cooled, to/from said body (70). The body (70) has at least one frame (71) on the door (20) side. At least one gasket (40) is positioned between said door (20) and said frame (71) for providing sealing. Moreover, at least one door opening assistant (80) is positioned at a location on the body (70) which is essentially close to the door (20). At least one pusher (82) is positioned on said door opening assistant (80), and said pusher (82) can be moved towards the door (20) preferably by means of a drive element.

With reference to Fig. 2, there is at least one gasket channel (21) and at least one press plate (30) on the door (20). Said gasket channel (21) has a grooved structure in a manner extending along the periphery of the door (20), and said gasket (40) is positioned on the door (20). The gasket (40) has at least one adhesion region (41) essentially on the side thereof facing the frame (71) for providing holding thereof to the frame (71). In a preferred embodiment of the present invention, magnetic materials can be positioned in said adhesion region (41). At least one channel (42), which is in groove form, is positioned on the gasket (40) on the side of the adhesion region (41) facing the gasket (40). In a preferred embodiment of the present invention, said channel (42) extends along the gasket (40).

Said press plate (30) positioned on the door (20) essentially has an L-like form. While the press plate (30) is connected to the door (20) by means of at least one fixation end (31) from one side, it has at least one carrying end (32) on the other side thereof. Said carrying end (32) is essentially positioned mutually with said door opening assistant (80). At least one gasket holder (50) is positioned between the door opening assistant (80) and the press plate (30). Said gasket holder (50) is connected to the press plate (30) by means of at least one guide pin (60) from one side thereof. The gasket holder (50) enters into the channel (42) by means of at least one holding end (51) from the other side thereof. At least one connection element (52) is used in the connection of the gasket holder (50) to the guide pin (60). The guide pin (60) has at least one pin end (61). Said pin end (61) is essentially configured to be narrower than the guide pin (60). Depending on this, at least one step (62) is formed between the guide pin (60) and the pin end (61). The pin end (61) is connected to the press plate (30) by means of said movement channel (33). The pin end (61) enters into the movement channel (33) and the removal of said pin end (61) from the press plate (30) is prevented by means of the fixation element (64). The width of the pin end (61) is greater than the width of the movement channel (33). Depending on this, at least one gap (63) is formed between the step (62) and the movement channel (33). The pin end (61) can move linearly in the axis of the movement channel (33) at an amount equal to said gap (63) distance. Moreover, at least one elastic element (65) is positioned between the press plate (30) and the gasket holder (50). In a probable embodiment of the present invention, said elastic element (65) is a flexible helical spring and is preferably positioned around the guide pin (60).

With reference to Fig. 3, said door opening assistant (80), which is provided on the body (70), is essentially positioned mutually with the gasket holder (50). The door opening assistant (80) has at least one control unit (81) and at least one pusher (82). Said pusher (82) is configured to provide diverging of the gasket holder (50) from the frame (71) depending on the command received from said control unit (81). As the pusher (82) pushes the gasket holder (50), the adhesion region (41) is at least partially separated from the frame (71). By means of this, the air medium existing inside the body (70) and existing outside the body (70) are joined. The joining of the air medium provides balancing of the air pressure existing inside the body (70) and existing outside the body (70). By means of this, the difficulties, faced in opening the door (20) and which occur due to negative pressure inside the body (70) during the opening of the cooling device (10) door (20), are prevented.

In an examplary embodiment of the present invention, while the door (20) of the cooling device (10) is being opened, the door (20) is diverged from the frame (71). The press plate (30) and the gasket holder (50) also diverge from the body (70) together with the door (20) and separate the adhesion region (41) from the frame (71). In another examplary embodiment of the present invention, while the door (20) of the cooling device (10) is being opened, the pusher (82) pushes the gasket holder (50) by the control unit (81). As the pusher (82) pushes the gasket holder (50), the adhesion region (41) is separated from the frame (71) and the door (20) is opened. In another examplary embodiment of the present invention, the control unit (81) pushes the pusher (82) towards the gasket holder (50) at predetermined time intervals without needing opening of the door (20). As the gasket holder (50) is pushed towards the door (20), the adhesion region (41) is separated from the frame (71) from one side and the guide pin (60) realizes linear movement inside the movement channel (33) from the other side and compresses the elastic element (65). By means of this, the air pressure existing inside the body (70) and existing outside the body (70) are balanced without needing to open the door (20). By means of the elastic element (65), as the pusher (82) is diverged from the gasket holder (50), it pushes the gasket holder (50) towards the frame (71) and provides holding of the adhesion region (41) to the frame (71). This process can be repeated at predetermined time intervals or after a short duration after the door (20) is closed.
