Description

[Detailed Description of the Invention] The present invention relates to a refrigeration system, and particularly to a refrigeration system using an air-cooled condenser.

Conventionally, when using an air-cooled condenser in a refrigeration device such as a refrigerator or ice maker, an equipment storage room is formed at the rear lower part of the refrigeration equipment body, and the condenser is installed in this equipment storage room along with the compressor and blower. (See Figure 1), or by attaching only the condenser to the back of the main unit and using a blower to forcefully cool the high temperature, high pressure refrigerant gas flowing through the condenser, but this method takes up space in the equipment storage room. Due to the large size, the depth of the device becomes large, which not only increases the size of the device, but also has the disadvantage of poor cooling efficiency of the condenser.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a refrigeration system that is downsized by keeping the depth dimension small and that has improved cooling efficiency of the condenser.

In order to achieve the above-mentioned purpose, the refrigeration system of the present invention has an equipment storage chamber formed at the rear lower part of the main body by the inclined rear part extending toward the inside of the main body, and a condenser storage chamber formed at the bottom of the main body. The rear end communicates with the equipment storage chamber, and the front end thereof is opened, and a part of the back surface defining the equipment storage chamber is connected to the condenser storage chamber in a straight line from the top thereof. The space defined by the part of the back part is made narrower at the upper part by extending obliquely toward the rear end part, and the other part of the back part defining the equipment storage chamber is From the upper part to the lower part, a part of the back part is curved concavely to form two equipment storage chambers with different volumes, the compressor is stored in the equipment storage room with the larger volume, and the blower is installed in the equipment storage room with the smaller volume. and the blower is disposed near the rear end of the condenser storage chamber so that the outside air passing through the condenser storage chamber is directed toward the narrow upper part, and further defined by the back surface. Both equipment storage chambers are covered with a cover member with ventilation holes at the top.

With this configuration, not only can the depth dimension be shortened by slightly increasing the height of the device body, making the device more compact as a whole, but also the suction can be taken from the opening at the front end of the condenser storage chamber. By increasing the discharge speed of the outside air, the condenser can be efficiently cooled.

Other objects and advantages of the present invention will become more apparent from the following description.

Next, as a preferred embodiment of a refrigeration system using an air-cooled condenser according to the present invention, a type of refrigeration system that continuously produces ice cubes of a predetermined size and stores the obtained ice cubes in a water storage tank is described. The automatic ice making machine will be described in detail below with reference to the accompanying drawings.

2 and 3, the automatic ice making machine according to the present invention includes an ice making section 12 in which an ice making mechanism 10 is arranged, and an ice making section 12 in which an ice making mechanism 10 is arranged, and an ice making mechanism 1
A water storage tank 14 that receives and stores ice cubes produced by 0 through a water tray (to be described later) is integrally molded, and furthermore, a heat insulating material 1 is formed.
6, and an equipment storage chamber 20 provided at the rear lower part of the main body by a rear part 15 that is inclined so as to extend inward of the main body 18. A door 22 is provided at the front opening of the water tank 14 is attached so that it can be opened and closed freely.

On the other hand, a condenser storage chamber 26 is formed at the bottom of the main body 18 to accommodate a condenser 24 made of a wire capacitor, a fin-shaped condenser, etc. The air blower 28 is placed in the communication area between the condenser storage chamber 26 and the equipment storage chamber 20, that is, near the rear end of the condenser storage chamber 26, and the air blower 28 is used to open the front end of the The chamber 26 is configured to draw in outside air from the front end opening to cool (@condense) the high temperature and high pressure refrigerant gas flowing through the condenser 24.

In this case, a portion 15a of the back surface section 15 defining the equipment storage chamber 20 is moved obliquely from the upper part toward the rear end of the condenser storage chamber 26 to form the back surface section 1.
The space defined by the part 15a of the rear part 15 is configured to be narrow at the upper part, and the other part 15b of the back part 15 defining the equipment storage chamber 26 is made downward from the upper part of the back part 15. By curving a part 15a of 15 in a concave shape or in a dogleg shape with the bent part facing inward, two equipment storage chambers 20a having different volumes are created.
20b, the refrigeration system compressor 36 is stored in the equipment storage chamber 20a, which has a large volume, and the equipment storage chamber 20, which has a small volume.
0b, a blower 28 is arranged near the rear end of the condenser storage chamber 26 so that the outside air that has passed through the condenser storage chamber 26 is directed toward the narrow upper part, and the back side of the main body that defines the equipment storage chamber 20 is installed. By forming the ventilation hole 32 above a part of the cover member 30 that closes the condenser storage chamber 20b, it is possible to further increase the exhaust speed of the outside air taken in from the front end opening of the condenser storage chamber 26 by changing the volume of the storage chamber 20b. Therefore, the refrigerant gas can be efficiently cooled.

As is clear from FIGS. 2 and 3, the cover member 30
The total opening area of the ventilation holes 32 provided in the condenser storage chamber 2
It is substantially wider than the opening area of the front end of No. 6.

The ice-making mechanism 10 consists of an ice-making chamber 34 that opens downward and defines a large number of cells, and a compressor 36 and a condenser storage chamber 26 arranged in an equipment storage chamber 20a are arranged on the outer surface of each cell.
The evaporator 3 constitutes a refrigeration system together with the condenser 24 arranged in the
8 are arranged.

Below the ice making compartment 34, a drive motor (
A water tray 40 is provided, which is configured to be tiltable under the action of a cooler (not shown), and the water tray 40 is configured to be tilted during the deicing cycle to open the ice making chamber 34.

Further, an ice-making water tank 42 for storing ice-making water necessary for one ice-making cycle is provided at the bottom of the water tray 40, and the ice-making water in the ice-making water tank 42 is transferred to a water pipe (not shown) and a pump device 44. A fountain hole (not shown) drilled into the water pan through the
Freezing is carried out by supplying water from the fountain to the ice-making chamber, and the remaining frozen water is returned to the ice-making water tank 42 through a drainage hole (not shown) provided adjacent to the fountain hole, and further, at the end of the ice-making cycle. The frozen residue is configured to be drained to the outside via a drainage tray 46 by tilting the water tray 40.

Generally, if the upper part of the equipment storage room is simply wide, turbulence is likely to occur in that space, and when turbulence occurs, it creates resistance to the desired air flow from the bottom to the top of the equipment storage room. This will have an adverse effect and reduce the capacity of the refrigeration system.

However, in the above-described refrigeration system according to the present invention, the rear part of the main body defines an equipment storage chamber with a narrow upper part for a small volume blower and an equipment storage compartment for a large volume compressor. , these equipment storage chambers are covered with a cover member with ventilation holes at the top, and a part of the back of the main body is sloped linearly from near the rear end of the condenser storage chamber toward the top. Since the air is heated by the condenser in the condenser storage chamber and exits from the rear end of the condenser storage chamber, the air flows along a part of the back of the main unit that extends upward while sloping in a straight line. The airflow is smoothly guided without turbulence through the ventilation holes of the cover member, which has a total open area that presents virtually no resistance to the flow.

Therefore, according to the refrigeration device according to the present invention, the height of the device body is slightly increased and the condenser is placed in the storage chamber formed at the bottom of the device, so the depth dimension can be set short and the overall device can be made more compact. It has various advantages such as not only being able to reduce the space in the equipment storage room, but also increasing the capacity of the water tank and improving the cooling efficiency of the condenser. Although an automatic ice maker has been described as a preferred embodiment of the refrigeration device according to the present invention, the present invention is not limited to this embodiment and can be used within the scope of the spirit of the present invention. Of course, various improvements and changes can be made therein.
