Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view of a commercial refrigerator of the present invention, FIG. 2 is a front view of the commercial refrigerator of the present invention with a door removed, and FIG. 3 is a diagram showing the relationship between the heat insulating box and the door of the present invention. FIG. 4 is an enlarged sectional view of a main part showing a relationship between a partition and a door of the present invention.

Reference numeral 1 denotes a commercial refrigerator, which is installed in a kitchen room and has a front opening and a heat insulating box 3 having a storage room 2 therein, and a heat insulating door 4 for closing the front opening of the heat insulating box. It is composed of The heat-insulating box 3 is made of an outer box 5 made of a stainless steel plate, an inner box 6 made of a stainless steel plate incorporated at a distance inside the outer box, and a heat-insulating plastic connecting the opening edges of the two boxes. And an L-shaped breaker 7 having one side as a front surface, and a foam heat insulating material 8 filled in a space formed by both boxes 5, 6 and breaker 7.

Reference numeral 9 denotes a middle partition for vertically partitioning the opening of the heat insulating box 3, and the middle partition includes an outer plate 10 made of a stainless steel plate,
U-shaped inner plate 11 made of stainless steel plate facing the storage room 2
And an L-shaped breaker 7 made of a heat-insulating plastic provided on both sides connecting the outer plate and the inner plate and having one of the front surfaces, and a space formed by these two plates and the breaker. And the foamed heat insulating material 12 provided in the main body.

Two heat insulating doors 4 are provided above and below the front opening of the heat insulating box 3 with the partition 9 interposed therebetween, and a magnet gasket 13 is provided around the inner surface on the back side. . The magnet gasket includes a permanent magnet 14 having a magnetic force and a soft packing material 15 that holds the permanent magnet and seals a space between the front opening of the heat insulating box 3 and the heat insulating door 4.

An L-shaped front-side breaker 7 has a recess 16 which is open forward and is recessed rearward. The recess 16 has a magnetically attracted surface which forms an attracting surface for attracting the magnet gasket 13. The thin metal member 17 is mounted. The metal member 17 mounted in the recess 16 is fitted so as to form the same surface as the front surface of the breaker 7.

The magnet gasket 13 is configured such that when the heat insulating door 4 is closed, the permanent magnet 14 is attracted to the metal member 17 and the packing material 15 is deformed and contacts the breaker 7 so as to cover the metal member 17. .

A bent piece 18 bent inward of the opening edge of the outer box 5 on the opening side of the heat insulating box 3 and a bent piece bent inward of the opening edge side of the outer box 5 on the front face of the breaker 7. The piece 19 is joined to each other to form a joint 20.

A bent piece 21 formed by bending both ends of the outer plate 10 of the middle partition 9 inwardly and a bent piece 19 bent by the inwardly bent side of the outer plate 10 in front of the upper and lower breakers 7 are joined to each other. The joint 22 is formed.

Reference numeral 23 denotes a heating element such as an electric heater or a heating pipe for preventing dew condensation. The heating element is inserted into a concave portion 24 formed in a bent piece 19 of the breaker 7 and is turned into a bent piece 18 of the outer box 5. And the bent piece 21 of the outer plate 10 respectively. The recess 24 has substantially the same shape and the same size as the heating element 23.

In the storage constructed as described above,
Stainless steel plate outer box 5 and stainless steel plate inner box 6
The inside space is filled with foam insulation 8 to form the heat insulation box 3 and both sides of the edge of the outer plate 10 made of stainless steel and the inner plate 11 made of stainless steel. The breaker 7 which is connected to the inner space and forms the partition 9 by providing the foamed heat insulating material 12 in the interior space is formed in an L-shape with heat-insulating plastic. Heat leakage due to a temperature difference from the outside, which has a higher temperature, can be suppressed.

The metal member 17 provided on the front face of the breaker 7 facing the magnet gasket 13 is mounted on the recess 16 so as to be flush with the front face of the breaker 7, so that no step is formed on the recess 16. In this manner, dust is prevented from accumulating around the inside of the concave portion, and the metal member 17 mounted on the concave portion 16 is lifted up by the step of the concave portion 16 on the contact surface side of the packing material 15 of the magnet gasket 13. The storage room 2 and the outside of the storage are not exposed.

The metal member 17 is magnetically attracted by the permanent magnet 14 when the heat-insulating door 4 is closed, and is covered with the packing 15 that contacts the front surface of the breaker 7, so that the cool air in the storage room 2 and the outside air outside the refrigerator can be removed. To prevent heat leakage due to heat conduction.

The metal member 17 can be made thinner by bringing the entire surface thereof into close contact with the bottom in the recessed portion 16, and the heat conduction of the metal itself is reduced, so that the inside of the storage room 2 and the outside of the storage room are reduced. And the amount of heat leak between them can be reduced.

The heater 23 for preventing dew condensation is provided in the concave portion 24 of the bent piece 19 of the breaker 7 joined to the bent piece 18 of the outer box 5 of the heat insulating box 3 or the bent piece 21 of the outer plate 10 of the middle partition 9. By inserting the breaker 7, the breaker 7 can be fixed simply by being incorporated into the outer box 5 and the inner box 6 of the heat insulating box 3 and the outer plate 10 and the inner plate 11 of the partition 9. The heating element 23 inserted into the recess 24 of the breaker 7 is connected to the bent portions 18 of the outer box 5 of the heat insulating box 3 and the outer plate 10 of the partition 9 at the joints 20 and 22.
By contacting the bent piece 21 of the above, dew condensation on the outer box 5 and the outer plate 10 exposed to the outside is prevented. Further, since the heating element 23 is not thermally connected to the metal member 17 mounted on the recess 16 of the breaker 7, it is difficult to exchange heat with cold air in the storage room 2 via this metal member.

In the above description, the heating element 23 is inserted into the concave portion 24 of the bent piece 19 of the breaker 7, but the bent piece 18 of the outer box 5 and the bent piece of the outer plate 10 are bent. Piece 2
It is needless to say that the formation of the concave portion for inserting the heating element in 1 improves the workability of mounting the heating element and also has the effect of improving the efficiency of dew condensation prevention.
