Description

  • The present invention relates to a deep freezer having a door wherein the foodstuffs to be cooled are placed.
  • The deep freezer, also known as the chest type, comprises a single freezer compartment disposed in a body, the upper part of which is closed with a door. A compressor and a condenser are disposed in the machine compartment, at the lower part of the deep freezer body, known as the body base region, which is insulated from the freezer compartment and an evaporator is disposed behind the evaporator cover situated in the freezer compartment. Cooling of the foodstuffs placed into the freezer compartment is performed by forced convection by means of a fan disposed on the evaporator. Since the freezer compartment volume is generally of a monolithic structure, the foodstuffs to be cooled must be stacked in an orderly manner, which creates usage difficulties for users in the course of time. Although some stacking devices have been developed for this reason, the freezer compartment volume remains insufficient for users, and additional cooling volumes are needed.
  • In the state of the art German Patent Application No. DE102013004976 , a deep freezer is disclosed, comprising compartments which are attached to the freezer door.
  • In the state of the art United States Patent Application No. US2950157A , a deep freezer is disclosed, comprising a foldable shelf system which can be attached to the freezer door.
  • The aim of the present invention is the realization of a deep freezer which enables the foodstuffs to be cooled in the door.
  • The deep freezer realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body; a freezer compartment which is disposed in the body and wherein the foodstuffs are placed; an opening which provides access into the freezer compartment; a door which is suitable to be moved between a closed position where the door covers the opening and prevents access into the freezer compartment and an open position where the door provides access into the freezer compartment; an evaporator which is disposed in the body and which is configured to cool the freezer compartment; a compressor which is configured to compress the refrigerant fluid; a condenser which is configured to condense the refrigerant fluid; a drawer which is removably placed in a volume arranged on the door; at least one air duct which is provided on the door and which is configured to fluidly connect the freezer compartment and the volume; a fan which is disposed in the body and which is configured to deliver the cold air in the freezer compartment into the volume; and a discharge port which is provided on the door and which is configured to return the air delivered into the volume back into the freezer compartment. Thus, a volume is formed on the door which enables the cooling of the foodstuffs, and the cold air is delivered from the freezer compartment into the volume so as to ensure the cooling of the volume. Thus, the door of the deep freezer is enabled to be used in a more effective manner.
  • In an embodiment of the present invention, the door comprises a temperature sensor which measures the temperature of the volume, a heater which regulates the temperature of the volume, and a control panel which provides the control of the heater is disposed on the body. Thus, the volume is used as a freezer or fresh food compartment depending on the user's preference. The heater also prevents problems such as condensation, icing, and frosting caused by the temperature difference between the freezer compartment and the volume.
  • In an embodiment of the present invention, the heater is disposed on the surface of the volume facing the base of the drawer, and an insulation member is arranged on the door so as to substantially cover the opening. Thus, the volume is enabled to be heated more effectively and the freezer compartment is prevented from being affected by the temperature of the heater.
  • In an embodiment of the present invention, two drawers are positioned side by side in the volume, and the air duct supplies the air to both drawers. Thus, the volume formed on the door is used more effectively, and both drawers are cooled simultaneously. Consequently, it is ensured that the cold air delivered into the volume is better circulated so as to provide balanced cooling.
  • In an embodiment of the present invention, the air duct is arranged so as to remain in a gap provided between the drawers. Thus, the air duct occupies less space and the drawer volume becomes larger.
  • In an embodiment of the present invention, the air duct is almost Y-shaped. Thus, the cold air in the freezer compartment is taken from a single point and simultaneously delivered to the drawers. Consequently, the cold air delivered to the drawers is enabled to be at the same temperature and is distributed homogeneously to the drawers.
  • In an embodiment of the present invention, the fan is positioned on the surface of the door facing the freezer compartment when the door is in the closed position. Thus, the fan more effectively draws the air from the freezer compartment and delivers the same into the volume.
  • In an embodiment of the present invention, the door comprises a sealing member which is arranged so as to surround the access opening and which ensures the sealing of the volume when the drawer is placed into the door. Thus, when the drawer is placed into the door, air leakage from the access opening to the outside is prevented. Consequently, the volume is enabled to be better insulated from the external environment, and energy efficiency is increased.
  • By means of the present invention, it is ensured that the foodstuffs are stored in a volume provided on the door and cooled without the need for an additional cooling unit.

  • The deep freezer (1) comprises a body (2); a freezer compartment (3) which is disposed in the body (2) and wherein the foodstuffs are placed; an opening (A) which provides access into the freezer compartment (3); a door (7) which is suitable to be moved between a closed position where the door (7) covers the opening (A) and prevents access into the freezer compartment (3) and an open position where the door (7) provides access into the freezer compartment(3); an evaporator (4) which is disposed in the body (2) and which is configured to cool the freezer compartment (3); a compressor (5) which is configured to compress the refrigerant fluid; and a condenser (6) which is configured to condense the refrigerant fluid. The deep freezer (1) is a chest-type deep freezer, and the door (7) is hinged to the body (2) so as to move vertically.
  • The deep freezer (1) of the present invention comprises at least one drawer (8) which can be moved in a volume (H) arranged on the door (7) and between a closed position wherein the drawer (8) is completely stored in the volume (H) and at least one open position wherein at least part of the drawer (8) is located outside the volume (H); at least one air duct (9) which is provided on the door (7) and which provides the air flow between the freezer compartment (3) and the volume (H); a fan (10) which is provided on the air duct (9) and which is configured to deliver the cold air in the freezer compartment (3) into the volume (H); and a discharge port (11) which is provided on the door (7) and which is configured to return the air delivered into the volume (H) back into the freezer compartment (3). The drawer (8) placed into the volume (H) provided on the door (7) is moved by sliding between the open position and the closed position. In order to cool the volume (H), and hence the inside of the drawer (8), the cold air is delivered from the freezer compartment (3) into the volume (H) by means of the fan (10) and the air duct (9). After circulating in the volume (H), the cold air delivered into the volume (H) is returned back into the freezer compartment (3) by means of the discharge port (11). Thus, the volume (H) provided on the door (7) is enabled to be cooled without using an additional cooling member, and an additional storage area is formed for the users.
  • In an embodiment of the present invention, the deep freezer (1) comprises a temperature sensor (12) which is provided on the door (7) and which measures the temperature of the volume (H), a heater (13) which regulates the temperature of the volume (H), and a control panel (14) which is provided on the body (2) and which provides the control of the heater (13). The temperature sensor (12) monitors the temperature of the air in the volume (H), and the control panel (14) enables the user to adjust the heater (13). The heater (13) also prevents problems such as condensation, icing, and frosting caused by the temperature difference between the freezer compartment (3) and the volume (H). When the user wants to use the volume (H) as a freezer, the user turns off the heater (13) via the control panel (14), and when the user wants to use the volume (H) as a cooling device, the user turns on the heater (13) via the control panel (14). Thus, the volume (H) is used as either a cooling device or a freezer.
  • In an embodiment of the present invention, the deep freezer (1) comprises the heater (13) which is positioned on the side of the door (7) facing the freezer compartment (3) and an insulation member (15) which is provided on the door (7) and which provides thermal insulation between the volume (H) and the freezer compartment (3). The insulation member (15) is positioned on the surface of the door (7) facing the freezer compartment (3) so as to almost completely cover the opening (A). Thus, the heat transfer between the volume (H) and the freezer compartment (3) is almost completely prevented.
  • In an embodiment of the present invention, the deep freezer (1) comprises two drawers (8) which are arranged side by side in the volume (H) on the door (7) and the air duct (9) which supplies the air to both drawers (8). The two drawers (8) arranged side by side on the door (7) provide ease of use for the users. By delivering the air to both drawers (8) simultaneously through a single air duct (9), both drawers (8) are enabled to be cooled homogeneously, and the need for using additional components is eliminated, enabling the deep freezer (1) to be manufactured in a more cost-effective manner.
  • In an embodiment of the present invention, the deep freezer (1) comprises the air duct (9) which is arranged to remain in a gap (B) provided between the drawers (8). Providing the gap (B) between the drawers (8) reduces the heat transfer between the drawers (8) and enables the air duct (9) to be positioned at that point. Thus, the air duct (9) is enabled to be more easily positioned on the door (7).
  • In an embodiment of the present invention, the deep freezer (1) comprises the air duct (9) having a substantially Y-shaped form. Thus, the air is drawn from a single point in the freezer compartment (3) and delivered to the drawers (8) at equal flow rates. Thus, both drawers (8) are enabled to be at the same temperature.
  • In an embodiment of the present invention, the deep freezer (1) comprises the fan (10) which is positioned on the surface of the door (7) facing the freezer compartment (3) when the door (7) is in the closed position. The fan (10) is positioned on the air duct (9) and directly draws air from the freezer compartment (3) so as to direct the same into the volume (H). The positioning of the fan (10) on the inner surface of the door (7) provides ease of assembly and enables the maintenance to be performed more quickly and easily.
  • In an embodiment of the present invention, the deep freezer (1) comprises a sealing member (16) which is arranged on the door (7) so as to surround the access opening (EA) and which provides the sealing of the volume (H) when the drawer (8) is placed into the door (7). The sealing member (16) is preferably manufactured from rubber material and prevents the air in the volume (H) from leaking into the external environment when the drawer (8) is placed into the door (7).
  • By means of the present invention, a deep freezer (1) is realized, wherein the volume (H) formed on the door (7) is cooled by the air in the freezer compartment (3) and the foodstuffs are stored in the door (7).
