Description

TECHNICAL FIELD The present invention relates to a refrigerating storage condensing unit, which is installed in a machine room defined on a cooling storage main body, in a cooling storage.

(B) Conventional Technology As a conventional technology, for example, Japanese Patent Publication No. 63-27628 discloses that
A machine room is defined on the upper surface of the top wall of the main body by a cover with ventilation holes and left and right side plates, and a left side of the machine room contains a cooler and a circulation device for supplying cool air to the room. Disclosed is a commercial refrigerator having a lid and a refrigerating device including a refrigerating compressor that constitutes a refrigerating cycle together with a cooler, a forced ventilation type plate fin type condenser and an axial flow type blower on the right side.

(C) Problems to be Solved by the Invention According to such a conventional technique, when the air sucked from the ventilation port passes through the condenser, the condenser is cooled, whereby the air whose temperature has risen is kept in the machine room. The heat is exhausted from the upper and rear surfaces of the. However, most of the conditions for installing a refrigerator are such that the back surface of the main body is attached to the wall surface, so if items are randomly placed on the upper surface of the machine room in this state, in addition to the rear surface of the machine room, The exhaust heat space is also lost, and the exhaust heat efficiency is extremely deteriorated, causing a decrease in the cooling capacity in the refrigerator.

In view of such a conventional technique, the present invention provides a cooling storage box that enables an article to be stably placed on the upper surface of a machine room without damaging the exhaust heat space and effectively uses the space. is there.

(D) Means for Solving the Problems In order to solve the above problems, the present invention provides a machine room partitioned by a front grill on the cooling storage main body, the upper surface of which is open and both side walls and front surfaces have suction ports. In the cooling storage, in which the electric compressor and condenser of the refrigeration system and the air blower for cooling the condenser are installed in the machine room, the machine room has an upper surface from a rear surface of the machine room. In the cooling storage, an article placing member having a stopper surface projecting upward is provided at a front position so as to extend across the both side walls.

(E) Action The present invention allows the article (13) to be stably placed on the open upper surface of the machine room (8) due to the presence of the placing plate (12), and the space above the machine room (8) can be secured. It can be used effectively.
Moreover, since the stopper surface (12A) is formed on the mounting plate (12), the heat exhaust space (14) on the upper surface of the machine room (8) can be secured.

(F) Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

(1) is a cooling storage main body of an insulating structure having an opening / closing door (2) at a front opening, and a refrigeration system cooler (3) and a cool air circulation blower (4) are provided in an upper part of the main body (1). It is arranged. Further, on the main body (1), a front grill (6) having a suction port (5) and left and right side plates (7) as side walls.
A) and (7B) form a machine room (8). Therefore, this machine room (8) has an open top and back surface,
In the machine room (8), a condensing unit including an electric compressor (9) and a condenser (10) that form a refrigeration system together with a cooler (3) and a condenser air-cooling blower (11) is installed. ing. The blower (11) is installed on the windward side of the compressor (9) and on the leeward side of the condenser (10), and the air sucked from the suction port (5) of the grill (6) is transferred to the condenser (10), After cooling the compressor (9), heat is exhausted from the upper and rear surfaces of the machine room (8).

Thus, a substantially vertical projection is provided on the upper surface of the machine room (8) in front of the rear surface of the machine room (8), that is, above the blower (11) which is the boundary between the low pressure side and the high pressure side. Stopper surface (12
An article placing plate (12) having A) is installed. The mounting plate (12) is fixed to the upper surfaces of both side plates (7A) and (7B) of the machine room (8), and is placed across both side plates (7A) and (7B). Further, the mounting plate (12) has a front end extending to the upper surface of the grill (6) so as to close the lower surface of the machine room (8) on the low pressure side.

In the above configuration, the placing plate (12) is used as a storage place for articles (13) such as storage boxes and tools, and the article (13) should be stably placed on the placing plate (12). As a result, the upper space of the machine room (8) can be effectively used, and the movement of the article (13) in the depth direction is restricted by the stopper surface (12A). The exhaust heat space (14) will always be secured. Therefore, as shown in FIG. 1, the back surface of the main body (1) is
Even when installed on the wall surface (15) exactly, there is no worry because the exhaust heat space (14) is secured as described above. Moreover, since the mounting plate (12) closes the upper surface of the machine chamber (8) on the low pressure side, it is possible to prevent a short cycle of the exhausted air.

Next, FIG. 3 shows another embodiment of the present invention, which is a rear mounting plate (12) having a stopper surface (12A) projecting upward at the same position as the above embodiment, and a front plate parallel to this. Placement plate (12
B) is provided, and it is not possible to prevent the short cycle as in the embodiment, but in other respects, the same effect as the embodiment is exhibited. Regarding the front mounting plate (12B), the upper surface of the grill (6) can also serve as the front mounting plate (12B).

(G) Effect of the Invention As described above, according to the present invention, since the placing plate having the stopper surface is provided on the upper surface of the machine room, the article can be placed on the upper surface of the machine room without impairing the efficiency of heat exhaustion from the upper surface of the machine room. It can be stably placed and contributes significantly to organizing kitchen rooms and the like.
