[0002]

2. Description of the Related Art As a conventional technique, Japanese Patent Application Laid-Open No. 2-1405
The one shown in Japanese Patent Publication No. 78 is known. This cools the inside of the cool box by the cooling action of the thermoelectric conversion element having a cooling part that exhibits a cooling action by energization and a heat dissipation part that exhibits a heat dissipation action, and cools the heat dissipation surface side of the thermoelectric conversion device by a cooling fan. Therefore, the door of the cool box was opened and closed by a hinge. For example, when the hinge is arranged outside the cabinet frame, the hinge protrudes, and if it is adjacent to another cabinet, the hinge part becomes a gap and the appearance becomes poor, and the cabinets are closely attached. Can't do it. Further, when the hinge is arranged inside the cabinet frame, since the hinge is arranged within a limited space, the inside of the cool box is narrowed by the protrusion of the hinge. For example, Japanese Patent Application No. 5-17682
No. 5 solves the above-mentioned problems of the prior art. This is a thermal insulation space formed by a box-shaped heat insulation wall having an opening at the front and an insulation door having an opening at the opening, and the cooling section is brought into thermal contact with the cold insulation space, and the heat dissipation section is thermally exposed to the atmosphere. The thermoelectric conversion element is in contact with the storage case, and the storage case is housed in the cold storage space and integrally provided with the heat insulating door. The storage case is rolled by a rail member provided outside the cold storage space.

[0003]

In the above-mentioned prior art, the storage case is supported by the rail member located outside the cool box. This is arranged outside in order to reduce the cooling loss due to the rail member. However, since it is supported by the lower part, the upper part becomes unstable, which causes a relative displacement between the insulating door on the moving side and the insulating space on the fixed side, which causes interference when the drawer is opened. Or, when it is closed, the gap between the frame of the cool box and the drawer is conspicuous and the appearance becomes poor.

An object of the present invention is to reduce the relative displacement between the drawer portion and the heat insulation space.

And a rail member 15 disposed outside the heat insulating space 13 and movably affixing the heat insulating door 12.
This cool box 10 is housed in a cabinet 16 arranged adjacent to a vanity or the like. In addition, a duct 17 extending downward from above the cool box 10 is formed. The lower end of the duct 17 is opened as an intake port 18 on the lower front surface of the cool box 10, and the upper end of the duct 17 is set at the cool box 10.
An exhaust port 19 is opened on the front surface above.

The heat insulating door 12 comprises a heat insulating material 20 and a frame body 21. A moving rail member 22 of the rail member 15 is integrally fixed below the frame body 21.

The moving-side rail member 22 is held by a fixed-side rail member 23 arranged outside the heat insulating space 13 and is rollable in the longitudinal direction. Also, the heat insulating material 20
A storage case 37 is fixedly attached to the heat insulating space 13 by means of screws 24 so that the storage case 37 can be taken in and out of the heat insulating space 13.

The box-shaped heat insulating wall 11 is provided with a heat insulating material 25 inside and a frame 26 is provided outside the heat insulating material 25. The heat insulating door 12 described above can open and close the opening of the box-shaped heat insulating wall 11 by the rail member 15.
A packing 27 is provided on the contact surface between the heat insulating door 12 and the box-shaped heat insulating wall 11 to ensure airtightness.

One end of the heat transfer block 28 is in contact with the cooling surface of the thermoelectric conversion element 14, and a heat insulating material 29 is arranged around it. Further, the heat radiation surface of the thermoelectric conversion element 14 is in contact with a radiation fin 30 that radiates heat. A blower fan 31 that blows cooling air to the radiation fins 30 is disposed inside the duct 17 on the opposite surface of the radiation fins 30. The heat absorbing plate 32 is disposed on the inner surface of the heat insulating material 25 and is in thermal contact with the other end of the heat transfer block 28.

The tilt adjusting device 36, which is a feature of the present invention, will be described.

As shown in FIG. 2, the tilt adjusting device 36 is provided.
Is composed of a plate 33 disposed below the fixed rail member 23 and an adjusting screw 34 located on the lower surface of the plate 33. Since the plate 33 supports the fixed side rail member 23, the plate 33 is supported by the adjusting screw 34 located on the lower surface of the plate 33.
Can be tilted. Further, the plate 33 can be adjusted by using the fixing screw 35 loosened at the time of adjustment.

Next, the operation of this embodiment will be described.

The cool box 1 is operated by an operation switch (not shown).
When the switch supporting the start of cooling of 0 is turned on, the thermoelectric conversion element 14 is energized and at the same time the motor for driving the blower fan 31 is energized. When the thermoelectric conversion element 14 is energized, cooling is started on the cooling surface, and heat is exchanged with the heat absorbing plate 32 via the heat transfer block 28 that is in thermal contact with the cooling surface. To be cooled. Since the heat absorbing plate 32 further exchanges heat with the air in the heat insulating space 13, the air in the heat insulating space 13 is cooled. At this time, the air in contact with the vertical portion 32a and the ceiling portion 32b of the heat absorbing plate 32 is cooled and moves downward. In this way, the entire cool box 10 is cooled.

Further, the heat generated by the heat radiation surface exchanges heat with the heat radiation fin 31, and the heat radiation fin 31 is connected to the duct 17
Heat exchange with the air inside. In the duct 17, the blower fan 31 is rotated by the driving of the motor, air is taken in through the intake port 18, passes through the duct 17, and is exhausted through the exhaust port 19. Therefore, the heat radiation fins 31 efficiently exchange heat by this air flow.

As described above, according to the first embodiment, since the inside of the cool box 10 is cooled by the cooling surface of the thermoelectric conversion element 14, it is possible to provide a clean space in which bacteria and the like are unlikely to propagate.
Cosmetics can be placed in this space, for example. When using this cool box 10, pull out the heat insulating door 12,
If a displacement occurs during use, the inclination can be adjusted by the adjusting screw 34. At this time, the fixing screw 35 is loosened and then the adjusting screw 34 is adjusted. The adjustment screw 34 can be inclined to the rail member 15 by adjusting the adjustment screw 34 for eliminating the inclination of the drawer portion, and the positional deviation of the drawer portion can be eliminated. For example, when tilting to the right, the left and right adjusting screws 35 are fixed at the lowermost ends during assembly, so the right adjusting screw 35 is adjusted to raise the right side. Further, when the positional deviation occurs due to the dimensional variation of each material during the assembling, the positional deviation can be adjusted during the assembling. As a result, the positional deviation caused by being supported by the rail member 15 under the drawer portion can be adjusted during assembly or by the user, and the positional deviation can be adjusted to the open state. It is possible to solve the problem that the time difference is conspicuous and the appearance is deteriorated when the closed state is caused.

[0021]

According to the invention described above, it is possible to easily adjust the dimensional variation of each material at the time of assembly, and
It is easy for the user to adjust, and it is possible to reduce the relative displacement between the drawer portion and the heat insulating space.
Since the positional deviation can be prevented, the appearance does not deteriorate and the frame body and the drawer portion do not interfere with each other.

According to the second aspect of the invention, since the adjustment can be performed by the screw, fine adjustment can be performed.
