[0003]

[Problems to be solved by the device]

 However, in the conventional inlet frame structure for a freezer of this type, since the heater wire mounting groove e is formed in the wooden inlet frame a and the heater wire f is disposed in the mounting groove e, the heater wire f is disposed. There is a problem in that the heat of f is difficult to be transmitted, there is a heat loss, and dew condensation occurs on the outer surface of the entrance frame a due to the temperature difference between the inside and the outside of the refrigerator.

The present invention has been made in view of the above circumstances, and provides an inlet frame structure for a freezer in which heat loss of the heater wire is reduced and dew condensation of the inlet frame can be sufficiently prevented. The purpose is.

[0005]

Means for Solving the Problems In order to achieve the above object, the structure of an inlet frame of a freezer according to the present invention has a structure in which the inside of the refrigerator and the outside of the refrigerator are separated from each other in a portion where the packing on the door side is located in the inlet frame of the refrigerator. A conductive metal decorative plate is provided, a heater wire mounting groove is formed in the part of both decorative plates where the packing is located, the heater wire is arranged in this mounting groove, and these heater wires are covered. As described above, the packing receiver is attached.

In this invention, the decorative plate may be formed of a metal member having heat conductivity, and may be formed of any metal member, for example, an extruded aluminum alloy profile. .

[0007]

[Action]

 According to the freezer inlet frame structure of the present invention configured as described above, the heater wire is directly attached to the metal decorative plate having good heat conductivity, and both decorative plates are separated into the inside and the outside of the refrigerator. By heat insulation cutting, the heat of the heater wire inside the cabinet is transferred to the decorative plate inside the cabinet to prevent the packing from freezing, and the heat of the heater wire outside the cabinet is transferred to the decorative plate outside the cabinet to outside the cabinet. It is possible to prevent dew condensation on the surface of the decorative plate. Therefore, the heat loss of the heater wire can be reduced and the dew condensation on the inlet frame can be sufficiently prevented.

[0008]

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 is an inlet frame of a freezer, and a door 3 made of a heat insulating material for covering an opening 2 thereof is attached to the inlet frame 1 via a hinge 4 so as to be openable and closable. A handle 6 having a latch 5 is attached to the free end side of the door 3, and a latch receiver 7 with which the latch 5 is engaged is provided on the entrance frame 1 by an emergency evacuation bolt 9 having a knob 8 inside the cabinet. It is mounted so that it can be removed from the inside. A packing 10 is attached to the inner peripheral edge of the door 3 to seal it from the entrance frame 1.

The inlet frame 1 is provided on the periphery of the opening 2 of the freezer wall 11 made of a heat insulating material, and specifically, a wooden inner plate 12 arranged on the inner peripheral portion of the opening 2. A wooden outer plate 13 arranged on the outer surface of the storage wall 11 is assembled into an L-shaped cross section. The entrance frame 1 is provided with decorative plates 14 and 15 made of aluminum alloy, which are separated into the inside and outside of the compartment at the portion where the packing 10 on the door side is located. Both the decorative plates 14 and 15 are made of an extruded profile made of aluminum alloy, and the decorative plate 14 inside the cabinet is formed in an L-shaped cross section so as to cover the corner portion of the inner plate 12, and the packing thereof. The end portion on the opposite side to the 10 side is fixed to the inner plate 12 by tapping screws 16. The decorative plate 15 on the outer side of the refrigerator is formed in an L-shaped cross section so as to cover the outer surface of the outer plate 13, and its end opposite to the packing 10 side is fixed to the outer plate 13 by a nail 17.

A plurality of heater wire mounting grooves 18 that are open to the outside are formed along the longitudinal direction in the portions of the both decorative plates 14 and 15 where the packing 10 is located. 19a and 19b are provided. In this case, the heater wire 19a provided on the interior decorative plate 14 prevents the packing 10 and the like from freezing, and the heater wire 19b attached to the exterior decorative plate 15 is exposed to the outside of the entrance frame 1 surface. In other words, the role of preventing condensation on the surface of the decorative plate 15 on the outside of the refrigerator is divided. The heater wires 19a and 19b are covered with the heater wires 19a and 19b, and the packing receiver 20 with which the packing 10 is abutted is screwed into the inner plate 14 through the gap between the decorative plates 14 and 15. The tapping screws 21 are attached, and the ends of both the decorative plates 14 and 15 on the packing 10 side are fixed by the tapping screws 21 while being pressed through the packing receiver 20. The packing receiver 20 is formed of an extruded shape member made of an aluminum alloy, like the decorative plate.

The freezer inlet frame structure configured as described above has a decorative plate 14 made of aluminum alloy that is separated into an inside and an outside of the refrigerator at a portion where the packing 10 on the door 3 side is located in the inlet frame 1. , 15 are provided, a heater wire mounting groove 18 is formed in a portion of both decorative plates 14, 15 where the packing 10 is located, and heater wires 19a, 19b are disposed in the mounting groove 18 and the heaters A packing receiver 20 is attached so as to cover the lines 19a and 19b. Therefore, the heater wires 19a and 19b are directly attached to the aluminum alloy decorative plates 14 and 15 having good heat conductivity, and the decorative plates 14 and 15 are separated into the inside and outside of the refrigerator to be heat-insulated and cut. Therefore, the heat of the heater wire 19a inside the refrigerator is transferred to the decorative plate 14 and the packing receiver 20 inside the refrigerator to prevent the packing 10 from freezing, and the heat of the heater wire 19b outside the refrigerator is mainly The heat is transmitted to the decorative plate 15, and the role of preventing the dew condensation on the surface of the decorative plate 15 caused by the temperature difference between the inside and the outside of the container is shared, so that the heat loss of the heater wires 19a and 19b can be reduced and the inlet can be reduced. Condensation on the frame 1 can be sufficiently prevented. Further, since the heater wires 19a and 18b are covered with the packing receiver 20, it is possible to easily replace or repair the heater wires 19a and 19b only by removing the packing receiver 20.

[0013]

[Effect of device]

 In short, since the structure of the inlet frame of the freezer of the present invention is configured as described above, the following effects can be obtained.

1) Since the heater wire is directly attached to the metal decorative plate having good heat conductivity, and the decorative plate is separated into the inside and outside of the cabinet and heat-insulated, the heater wire inside the cabinet is The heater wire on the outside of the refrigerator mainly plays the role of preventing dew condensation, while the heater wire outside the refrigerator plays a role of preventing dew condensation. Thus, heat loss of the heater wire can be reduced and dew condensation on the inlet frame can be sufficiently prevented.

2) Since the heater wire mounting groove is formed on the decorative plate and the packing receiver is mounted so as to cover the heater wire disposed in the mounting groove, it is only necessary to remove the packing receiver. Can be easily replaced and repaired, and maintenance can be improved.
