Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for assembling a cooling device equipped with an evaporator and a blower, which includes: an inner box that partitions a cooling space in which the evaporator and the blower are installed; a restraining portion in contact with the front surface of the blower; A cover having both protruding parts extending in the same direction from both ends of the restraining part and defining a recess together with the restraining part is integrally molded, and the inner box and the cover are cut along the cutting line. is placed in the inner box through the cutting opening, the cutting opening is covered with a cover, the blower motor is held down by the stopper, and a fan is provided between both protrusions to supply cool air to the evaporator in the recess. L-1 is a pass-through type low temperature showcase that defines a part of the cold air passage that guides the cold air to the fan and improves the strength of the cover. Four resin columns (5) are erected at the four corners of the base, and three resin upper frames (6) connect the top ends of each column.
, a metal decorative frame (7) for stacking the above-mentioned pillars and upper frame, and transparent doors (8) with left and right openings slidably arranged in the openings for storing and taking out products on both the front and back sides. )(8) and
A transparent ceiling wall (9) made of glass etc. placed on the top surface, a transparent left side wall (transparent) placed on the left side, and a right wall of the storage room (2) that connects the storage room (2) and the machine. It is composed of a partition plate αυ that partitions the chamber (3), and there is a transparent glass (12A) inside.
and a shelf frame (12B) surrounding the swamp, and a lighting device 01 such as a fluorescent lamp along both openings.
is installed. In addition, the partition plate UυI is the storage room (
2) and the machine room (3) are connected to the upper e(
, is formed at the bottom of the suction port 0Q. Further, (roll) is a shelf support member erected along each support column, and a plurality of holes (16A) are formed for inserting and locking shelf supports αη for receiving the shelf (6).

The pillars (5), the upper frame (6) and the decorative frame (7) constitute the framework of the storage room (2).

The machine room (3) has an outer shell made up of a front plate (E), a rear plate (G), an outer plate having an angular cross-section, and a machine room space 0υ. In addition, the inside of the machine g (a) is equipped with a partition wall filled with a heat insulating material (33A) such as urethane foam, and a closing plate (b) that closes the opening (end) of this partition wall. ::1 The road is divided into a cooling space and a condensing space. An evaporator tube and a blower for forcedly circulating the low-temperature cold air heat exchanged by the evaporator are installed in the cooling space, and a drain tank is installed under the machine base plate ■. . Further, in the condensing space (), there are installed a compressor (1), a condenser (-), which together with the evaporator constitute a refrigeration cycle, as well as a condenser blower (6). The ring is a support member that supports the evaporator (goods) and the blower (2), and the left and right side walls (43A) that serve as both the left and right tube plates of the evaporator tube, and the upper II (4)
3B) and a duct-shaped eno (supporting part) and a blower fan with a bottom 1 m (43C) formed with multiple small drainage holes (43C') to guide dew from the evaporator tube downward. (
38F), and a cooling space in which a cooling passage through which cool air circulates is formed as shown by the arrow, a partition wall that partitions the high pressure side and the low pressure side, and a blower (44A). ), the motor (38M) is covered with a heat insulating material such as glass wool surrounding the motor, and the air blower cover closes one of the partition walls (to) along with the closing plate.
(hereinafter referred to as a cover.i,)
property).

The cover has a holding part (4) that holds down the motor (38M).

) (46B). The deterrent part (4
6A) and both protrusions (46B) (46B), the cold air is directed toward the fan (38F) provided between the two protrusions as shown by the arrow (). 46C) is formed.The partition wall (2) includes a foam insulation material (33A), an inner box (33B) that covers the surface of the insulation material on the cooling space side, and a surface of the insulation material (33A) on the condensation space side. The inner box (33B) includes a top wall (33B+) and side walls (33B, ) (33B2) extending downward from both the front and rear edges of the top wall.
, a lower wall (338g) facing the top wall (33B), and a hanging wall (338g) extending downward from the opening side tip of the lower wall.
84), the peripheral wall (33B) of the opening, the flange portion (33Bs) formed on this peripheral wall, and both ill!
(33B!) A mounting protrusion (33B!) formed at the lower end of 33B (33B2) to protrude inward, on which the Enoku support part is placed.
') (33Bg'). Portrait, (3
3Bs is a groove formed in order to drain the unboxed water downward.

As shown in FIG. 5, the inner box (33B) and the cover are manufactured as an integrally molded body by vacuum integral molding using resin as a material, and the inner box (33B) and the cover are manufactured as an integral molded body by vacuum molding using resin as a material. This is formed by cutting along line -1'.

As is clear from FIG. 4, after the cover is cut, it is horizontally rotated 180'' and placed into the inner box through the cut opening of the inner box (33B).

Therefore, since the inner box (33B) and the cover are molded in one mold, the manufacturing cost of multiple molds can be reduced compared to the case where the inner box (33B) and the cover are manufactured on each side. - is placed into the inner box through the cut opening of the inner box (33B), and the blower motor (38M) is held down by the restraining part (46A). Since the recess (46C) is formed from the part (46B) (46B) and the restraining part (46A) to define a part of the cold air passage, both protrusions @ (46B) (46B) prevent the cold air from passing through. It acts as a guide to the fan (38F), and the cold air is blown into the fan (38F) smoothly.The strength of the cover is increased by forming both protrusions (46B) in a curved shape (B). can be raised.

As described above, the present invention includes an inner box that partitions a cooling space in which an evaporator and a blower are installed, a holding part that contacts the curved surface of the blower, and a recess extending in the same direction from both ends of the holding part and forming a recess together with the holding part. A cover with both protrusions defining the inner box and the cover are integrally molded by resin molding, and the inner box and the cover are cut.
Both protruding parts and a restraining part are arranged in the inner box through the cutting opening, the cutting opening is covered with a cover, and the blower motor is held down by the restraining part, and a fan is provided between both the protruding parts to close the recess. Since this part defines a part of the cold air passage that leads cold air to the evaporator, the inner box and cover can be arranged at the same time to reduce the cost of the part and to simplify the installation, as well as to provide a sufficient supply of cold air. i. Can be placed in position by installing the cover, and its installation
You can do it extremely easily □゛
