The ice making section of the ice making unit 3 includes:
An evaporator is provided, and a remote condenser 7 having a condenser 6 constituting a refrigeration cycle together with the evaporator and the compressor of the ice making unit 3 is installed in the outdoor O.

The condenser 6 is connected to the evaporator and the compressor by a refrigerant pipe 8 around which a heat insulating material is wound. Further, reference numeral 9 denotes a water supply pipe for supplying ice making water to the ice making unit of the ice making unit 3, and 10 denotes a drain pipe for draining water generated in the ice storage unit 2.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. still,
The black arrow is the blowing wind, and the white arrow is the suction wind.

The remote condenser 7 includes a condenser case 11 for housing the condenser 6, a temperature sensor S for detecting the temperature inside the condenser case 11, and a condenser cooling blower 12 for cooling the condenser 6. And an air volume adjusting device 13 for adjusting the amount of cooling air of the condenser 6.

In general, the temperature sensor S may also be used as a condensation temperature sensor (CT sensor) mounted at an appropriate position on the condenser 6 to detect the temperature of the condenser 6.

On one side of the condenser case 11 accommodating the condenser 6 and on the other side opposite to the one side, an inlet 14 and an outlet 15 are provided, respectively. 14 and the lower edge of the outlet 15
On the inner surface side of the condenser case 11, a large number of wind direction plates 16, 17 inclined upward and downward are provided.

Further, the condenser 6 comprises a number of cooling fins 6A provided at a predetermined interval, and a meandering refrigerant pipe 6B penetrating between the cooling fins 6A. The condenser cooling blower 12 includes a fan 12A.
And a fan motor 12B for rotating the fan 12A.
It consists of

Reference numeral 18 denotes a base on which the condenser 6 and the condenser cooling blower 12 are mounted.
It is attached to the inner bottom surface by an attachment member 19 such as a bolt.

Next, an air volume adjusting device 1 which is a main part of the present invention.
3 will be described.

The air volume adjusting device 13 is located between the condenser cooling blower 12 and the air outlet 15 in the condenser case 11, and adjusts the air volume discharged from the air outlet 15 in a lateral direction. It is provided to extend.

As one embodiment of the air volume adjusting device 13, the sheet member 2 made of a finely woven cloth, a vinyl sheet, or the like, for example, blocks the passage of air.
0, a winding member 21 provided on the upper part of the condenser case 11 to enable the winding of the sheet member 20, and a stay 22 provided on a lower edge of the sheet member 20 and extending in the lateral direction; A guide member 23 connected to the lower edge of the sheet member 20 and formed of, for example, a nylon thread, which is not affected by the passing wind as much as possible, for guiding the vertical movement of the sheet member 20; Reel 2 for winding
4 and a reel motor 2 for driving the reel 24 to rotate.
5.

The winding member 21 is constantly urged in the winding direction by an urging device such as a spring. When the guide member 23 is wound on a reel 24, the sheet member 20 moves downward. Then, by rotating the reel 24 in the reverse direction, the sheet member 20 is wound by the winding member 21.

The air volume adjusting device 13 may be provided between the inlet 14 of the condenser case 11 and the condenser 6.

With the above configuration, the temperature sensor S
When the temperature in the condenser case 11 becomes equal to or lower than the predetermined temperature, the sheet member 20 is moved downward as shown by the dotted line in FIG.

Further, the sheet member 20 is controlled to move downward in a stepwise manner in accordance with the temperature detected by the temperature sensor S, thereby preventing the condensation pressure of the condenser 6 from increasing more than necessary.

As described above, the sheet member 20 is moved downward as necessary to shield the air outlet 15. Therefore, even if the ambient temperature is low and the wind is strong at low outside air temperature, the inside of the condenser case 11 is not affected. The passage of wind can be prevented as much as possible, and a desired condensation pressure can be obtained.

For this reason, the temperature of the hot gas at the time of the ice removing step of the inverted cell type ice making machine, the plate type ice making machine, and the falling ice making machine can be kept at a sufficient temperature.

Further, when the ambient temperature is high and the outside air temperature is high, the sheet member 20 is wound around the winding member 21 and the air outlet 15 is opened, so that a desired refrigeration capacity can be obtained.

Further, the condenser cooling blower 12 may be operated while the air outlet 15 is blocked by the sheet member 20 of the air volume adjusting device 13, and the condenser 6 may be heated by the heat generated by the fan motor 12B. In this case, the air is blown from the outlet 15
Therefore, the inside of the condenser case 11 is short-cycled.

Further, it is desirable that both the inlet 14 and the outlet 15 be shielded by the air volume adjusting device 13 so that the condenser cooling blower 12 is operated. In this case, the wind heated by the heat generated by the motor circulates almost completely inside the condenser case 11, and a higher condensing pressure can be obtained.

Next, another embodiment of the present invention will be described with reference to FIGS.

In this embodiment, as the air volume adjusting device 13, movable air direction plates 26 and 27, which are inclined upward, are provided at the lower edges of the suction port 14 and the air outlet 15 and on the inner surface side of the condenser case 11. Are provided at the top, bottom, left and right.

Since the air volume adjusting device 13 has the same structure on the suction port 14 side and the outlet port 15 side, the description on the suction port 14 side also serves as the description on the outlet port 15 side.

As shown in FIG. 5 and FIG.
A connecting member 28 for moving a number of wind direction plates 26 in the same manner is provided at one end of the rotating shaft 2.
9 are provided.

A rotation support portion 30 is provided at a lower edge of the suction port 14, and rotatably supports the rotation shaft 29 of the wind direction plate 26. Further, a spur gear 31 is provided on the rotating shaft 29.

Further, a gear 32 meshing with the spur gear 31 is provided near the suction port 14 on the inner side of the condenser case 11.
A rotation motor 33 for rotating the motor is mounted.

Reference numeral 34 denotes a spur gear 31 which is a condenser case 11
This is a relief part to avoid hitting.

With the above-described configuration, the opening and closing angle of the wind direction plate 26 is adjusted as necessary in accordance with the temperature detected by the temperature sensor S. Since the shield is shielded as shown by the dotted line in FIG. 5, the passage of wind through the condenser case 11 can be prevented as much as possible, and a desired condensation pressure can be obtained even when the ambient temperature is low and the wind is strong.

Further, in the case of a high outside air temperature, as shown by the solid line in FIG. 5, since the inlet 14 and the outlet 15 are opened, a desired refrigeration capacity can be obtained.

Here, in the case of this embodiment, the suction port 14
Although the air volume adjusting device 13 is provided on both the air outlet 15 and the air outlet 15, either one of the suction port 14 and the air outlet 15 may be used, or the blower for cooling the condenser may be provided with the air volume adjusting device 13 closed. By operating the motor 12, the wind heated by the heat generated by the motor circulates almost completely in the condenser case 11, and a high condensing pressure can be obtained.

The embodiment in which the present invention is applied to an ice maker has been described above. However, any remote condensing type in which the condenser 6 is installed outdoors may be a showcase or a refrigerator. In addition to the ability to obtain the capability, in the case of performing defrosting by hot gas, the defrosting can be performed reliably.

[0045]

As described in detail above, according to the first aspect of the present invention, the cooling air volume of the condenser is made variable by the air volume adjusting device, and the cooling air volume is minimized under strong wind at low ambient temperature and low outside air temperature. Or, eliminate the cooling air.

Therefore, even if the ambient temperature is low and the wind is strong, the reduction of the condensation pressure can be prevented as much as possible.

According to the second aspect of the present invention, one or both of the suction port and the air outlet are shielded and the blower is operated, so that the air is short-circuited in the condenser case and the heat generated by the blower is condensed. The vessel can be heated.

Therefore, even if the ambient temperature is low and the wind is strong, the heat generated by the blower is used to prevent the condensation pressure from lowering.
