Since the water is separated by the rear wall (1e) and the rear wall (1e), if there is no watering guide, the water will escape to both sides and in front of the pad/l/ (4b) (towards the rear wall (1e)). Although the amount of bounce is reduced, in the example of the present invention, pad/l/ (4b) '''
Both R11l side and front (rear 4i (le) (llllI

2)...11iJ watering guide directly below (4c) (4c
) and the rear wall (1e), and this cooling water is again sent to the ice making cell (2) by the paddle (4b)...
・Since the splashing water is applied to fL, especially when the ice-making operation starts, the ice-making rises quickly, and the ice-making of small ice blocks in the ice-making cell (2) is carried out quickly, improving water sprinkling efficiency and ice-making efficiency. .

Also, in the case of the other example of the watering guide shown in FIG.
Since the cooling water is returned to this section, the amount of splashed water is increased as described above, and the direction of watering is also controlled by raising both walls (4d) above the water surface. This also shortens the ice making time.

In addition, in the example described above, the watering direction is controlled by raising the watering guide above the water surface, and both watering guides (4o) and (40) are raised from the bottom of the water tank (3) to make ice. Although it was designed to be integrated with the rear wall (1e) of the chamber (1) and partitioned, it does not necessarily have to rise above the water surface or the rear wall (1e).
There is no need to integrate it with the water tank (3), if you partition the water on the rear side of the water tank (3) in the front and back direction, the water tank (3) can be used when Bud A' (4b) rotates.
Since internal water is prevented from escaping to both sides of the paddle (4b) and to the front, the number of splashing sprinklers increases, the direction of watering is also regulated by the rear wall (1e), and the returning cooling water is also mainly directed to these two watering guides. (4C) Since the process returns to (4C), the ice making time is shortened, and both the watering efficiency and the ice making efficiency are improved, and the intended purpose is achieved.

(Effects of the present invention) Examples of the present invention are as follows, and the present invention has an ice making compartment (1) with a front opening (1b) surrounded by a peripheral wall (1a),
The ice making room (1) is placed downward on the earthen wall (IC) of the ice making room (1).
), an ice-making cell (2) that opens into the ice-making cell (2), a water tank (3) for storing ice-making water provided at the bottom (1d) of the ice-making chamber (1), and a water tank (3) for storing ice-making water provided at the bottom (1d) of the ice-making chamber (1); ) corresponds to f
c Pad 1v (4b) and the pad /L' whose rotation direction is to flip up the rear wall (1e) side of the ice making chamber (1) at 1α immediately below
(4b) both [provided close to 111! It consists of both watering guides (40) (4C) that partition the water on the inner and rear side in the front and back direction, and the rotation of the paddle (4b) causes the two watering guides (4c) (4c) to The ice making section (4) is equipped with a water sprinkler (4) installed at a position where substantially the lower half of the paddle (4b) is submerged so as to scoop up and sprinkle water partitioned by the ice cell (2) into the ice making cell (2). This ice maker has the following effects.

The water sprinkling device (4) uses a splash type using a paddle (4b) instead of a nozzle sprinkling method using a water pump as in the conventional example, so the structure is extremely simplified.
(3) must also be installed in the ice-making compartment (1) below the water sprinkling device (4), so there is no need to install a separate water tank outside the ice-making compartment as in the conventional nozzle watering system. The overall structure of the ice maker is extremely simple, the ice maker is compact, the cost is low, and it is easy to handle and economical.

In addition, due to the above-mentioned action of the watering guides (4c) (4c)..., the amount of splashed water per rotation of the pad/v (4b)... increases, so there is no need to increase the rotational speed too much. It is energy efficient and has good watering efficiency.
Moreover, the ice making time is shortened and the ice making efficiency is also good.

Furthermore, by raising the watering guide (4c) from the bottom of the water tank (3) above the water surface and integrating it with the rear wall (1e) of the ice-making compartment (1), watering efficiency and ice-making efficiency can be improved as described above. Also, the watering guide can be attached to both side walls (4d
) (4d) and the rear wall (4e) have a U-shaped cross section and are rotatable about the horizontal axis (4a), making it easy to install in the ice making compartment (1) even if the watering guide is large. , water sprinkling efficiency and ice making efficiency are both improved.
