Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a low-temperature storage in which a machine room is formed on an insulated box.

[0002]

2. Description of the Related Art Conventionally, this kind of low-temperature storage is disclosed in
Japanese Unexamined Patent Publication No. 2012254 (F25D23 / 02) discloses a commercial refrigerator having a unit room above a heat-insulating box and a double door.

[0003] The power supply lead wire of the heater for preventing dew- ing of the partition provided on the door is connected to the electrical box of the machine room through a notch formed at the bottom of the machine room panel.

[0004] Here, as shown in FIGS. 7 and 8, first, an adhesive is applied to a protection member 101 having a U-shaped cross section, and the protection member 101 is fitted into an edge of the notch 102 and fixed. .

[0005]

In the prior art as described above, when attaching the protective material to the notch, the adhesive is attached to the operator's hand due to the use of the adhesive, and the workability is poor. there were.

When other fixing parts are used without using an adhesive, there is a problem that the appearance is inferior and the cost is increased.

The present invention has been made in view of the above-described problems, and provides a low-temperature storage for improving the workability of attaching a protective material.

[0008]

According to the first aspect of the present invention, there is provided a heat insulating box having a front opening, and a heat insulating door for closing the front opening of the heat insulating box so that the front opening can be freely opened and closed. And a machine room provided on the heat-insulating box, and a machine room panel for closing and opening the front of the machine room in a low-temperature storage room, where wiring from the heat-insulating door is located, And a projection formed at both ends of the notch on the opening side, and a protective material having elasticity, which is fitted to the periphery of the notch, is locked by the projection, and has elasticity. .

As described above, when attaching the protective material to the notch,
The protection material is bent and fitted into the notch, and both ends of the protection material are locked by the protrusions.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a low-temperature storage provided with the present invention, FIG. 2 is a perspective view of a low-temperature storage with a machine room panel opened,
FIG. 3 is an enlarged view of a main part of the machine room panel, FIG. 4 is a perspective view of the protection member, FIG. 5 is a perspective view when the protection member is mounted on the machine room panel, and FIG. 6 is a state where the protection member is mounted on the machine room panel. It is a perspective view of.

FIG. 1 and FIG. 2 show a low-temperature storage device 1 equipped with the present invention, for example, a low-temperature storage device for brown rice, which cools brown rice at about 10 ° C., wherein a foam insulation material is filled and foamed between the inner and outer boxes. A heat-insulating box body 6 having an open front surface, two-sided door-type heat-insulating doors 7 and 8 in which the front opening of the heat-insulating box body 6 is openably and closably provided; A cooling unit that cools the inside of the heat insulating box 6, a machine room 9 including a compressor, a condenser, and the like that constitute a refrigeration cycle together with an evaporator (evaporator) provided in the cooling device; And a machine room panel 10 that is openably and closably closed.

The heat insulating doors 7 and 8 have handles 7A and 8A, respectively.
A and a keyhole 7B for locking the heat-insulating doors 7, 8 are provided. Although not shown, these left and right heat-insulating doors 7, 8 are provided.
Among them, one of the heat insulating doors (the left heat insulating door 8 in the present embodiment) is provided with a support provided with a heating device such as an electric heater.

A slit-shaped suction port 11 is formed in the machine room panel 10 and a control panel 12 connected to the electrical box 5 is exposed. Incidentally, 13
Is a pedestal with an adjuster for supporting the cold storage 1
Reference numeral 4 denotes a caster capable of moving the low-temperature storage 1, and reference numeral 15 denotes a filter provided on the suction surface side of the evaporator.

With the above configuration, an embodiment of the present invention will be described with reference to the drawings.

The wiring 16 of the electric heater described above is located near the hinge of the left heat insulating door 8, and the wiring 16 is connected to the electrical box 5. A notch 17 for wiring is formed on the lower left side of the machine room panel 10 in order to avoid interference with the wiring 16 of the electric heater.

The notch 17 is provided with a protective member 18 shown in FIG. The protective member 18 is formed of a soft resin having elasticity, such as polypropylene or nylon, and has a U-shaped cross section, and irregularities are continuously formed in a longitudinal direction so as to be easily bent in a direction indicated by an arrow in FIG. ing.

Then, as shown in FIGS. 5 and 6, the protective member 18 is bent so that the opening side of the U-shape is on the outside, and is fitted to the peripheral edge of the U-shaped notch 17 as shown by the arrow in FIG. Put in. In addition, regulating protrusions 19 are formed on opposite ends of the notch 17 on the opening side, and the regulating protrusions 19 prevent the protective member 18 from sliding. The shape and the like of the restricting projection 19 are not limited as long as they have the same function.

Therefore, since the left and right ends of the protective member 18 come into contact with the regulating projections 19 and are locked, and the protective member 18 has elasticity and is constantly urged outward, The attachment of the protective member 18 is completed by being locked to the regulating projection 19.

Here, since the protective member 18 is pressed by the urging force of the protective member 18, it is not necessary to use an adhesive or the like.

As described above, since it is only necessary to insert the protective member 18 without using an adhesive or the like, the workability of attaching the protective member 18 can be improved.

[0022]

As described above in detail, according to the first aspect of the present invention, when the protective material is attached to the notch, the protective material is bent and fitted into the notch, and both ends of the protective material are locked by the projections. Is done.

Therefore, it is possible to improve the workability of attaching the protective member without increasing the cost.
