In order to gain a divine advantage over similar businesses and attract customers, they are making strenuous efforts to differentiate themselves from other companies. As part of this effort, attempts are being made to provide immediate new changes to customers by using ball-shaped (spherical) ice cubes instead of conventional ice cubes. In view of these trends, the applicant has developed a new ice maker that can produce large quantities of transparent, irregularly shaped ice, and has patented its basic structure as an "automatic ice maker" on January 29, 1988. At the same time, on November 22 of the same year, he filed a patent application entitled ``Ice Guide Structure for Automatic Ice Maker'' for a mechanism that can smoothly guide ice blocks that fall from the first ice maker to the water storage seat during deicing operation. Ta. Since the present invention is newly proposed in connection with the latter ice guiding structure, its basic structure will first be explained in order to contribute to a basic understanding.

ている。A drain tray 69 is provided below the ice-making water tank 9 to drain remaining water from the ice making machine to the outside of the machine, and is fixed in front of the drain tray 69 and diagonally below the second ice-making chamber 12 which is in a horizontal position. An ice guide plate 67 is pivotally supported by the pair of supporting members 65 via a shaft 68. The ice guide plate 67 has a width slightly smaller than the width of the water tray 38, and a vertical dimension that can cover the entire upper surface of the second ice making chamber 12. The upper end of the ice guide plate 67 is positioned in contact with the vertical side plate 70 of the housing during the ice making operation.

に臨んでいる。A reversing lever 76 is protrudingly fixed at a portion of the ice guide plate 67 close to the shaft 68 at an angle θ with respect to the ice guide plate 67, as shown in FIG. 8, for example. This reversing lever 76 faces the movement locus of suppressing members 74 which are provided in a hanging manner and protrude from both sides of the water tray 38 which tilts during the deicing operation which will be described later.

Rotate clockwise. When the pressing member 74 further tilts, the ice guide plate 67 moves to the left of the perpendicular line P extending above the shaft 68, and finally collapses onto the upper surface of the second ice making chamber 12 in the inclined position, and moves upward. The second ice-making chamber 15 that is opened is allowed to cool. Therefore, the ice balls falling from the first ice making compartment 12 slide down the upper surface of the ice guide plate 67 and are smoothly guided to the ice storage (not shown) located below.

It is. However, in food and beverage facilities where ice consumption is generally large, such as suburban restaurants and hotels with large banquet halls, the automatic ice making machines become larger, and the structure of the ice making room also becomes larger accordingly. For example, as shown in FIG. 9, if the number of first ice-making compartments 13 and second ice-making compartments 15 is increased, the longitudinal dimension of the ice-making compartment 10 will inevitably become longer. For this reason, Fig. 9 (a
), the ice guide plate 67 is in a tilted position.
The upper surface of the ice-making compartment 12 cannot be completely covered, and some of the ice cubes get caught in the second ice-making compartment 15 that opens upward.
It no longer functions as an ice guide plate member, and the second
When the ice making compartment 12 returns to the horizontal position, ice blocks will be trapped between the two ice making compartments 11 and 12, causing a serious problem.

接続するよう構成したことを特徴とする。For this reason, as shown in FIG. 9(b), the size of the ice guide plate 67 is set to a size that can completely cover the upper surface of the second ice making chamber 12, and the size of the ice guide plate 67 is set so that it can completely cover the upper surface of the second ice making chamber 12. It is necessary to increase the opening angle when the ice chamber 12 is tilted. However, in this case, it is necessary to secure a large amount of internal space in the ice maker in both the horizontal and height directions, which has the disadvantage that the casing becomes even larger in terms of volume. In addition, the dimensions of each component including the ice guide plate 67 are increased, leading to an increase in manufacturing costs. Purpose of the Invention The present invention has been proposed in order to solve the problem in an appropriate manner in view of the above-mentioned problems. To smoothly guide a group of ice blocks falling from a first ice-making compartment to an ice storage without being obstructed by a second ice-making compartment in a tilted position during deicing operation in an automatic ice-making machine that produces irregularly shaped ice such as spherical ice. The purpose of the present invention is to provide an ice guide structure that allows the ice guide member to operate without requiring a large space within the ice maker. Means for Solving the Problems In order to overcome the above-mentioned problems and suitably achieve the intended purpose, the present invention has been devised to solve the problems described above.
A first ice-making compartment defining a large number of small ice compartments, a second ice-making compartment disposed tiltably directly below the first ice-making compartment and defining a large number of second ice-making compartments that open upward; It consists of a water tray that is fixed to the lower part of the second ice-making compartment and has a water fountain hole and a return hole that correspond to each second ice-making compartment, and an ice-making water tank that is integrally provided below this water tray. In the automatic ice making machine, the ice making water in the tank is injected from the water fountain hole to form ice cubes in both ice making chambers, and the unfrozen water is collected into the tank through the return hole. It is pivoted diagonally downward and normally blocks the falling trajectory of ice cubes, and when the second ice making compartment tilts from the first ice making compartment during deicing operation, it is energized and falls onto the top surface of the second ice making compartment. , an ice guide plate is provided for guiding the ice blocks falling from the first ice making room to the ice storage, and the ice guide plate is characterized in that a plurality of plate pieces are hingedly connected to a bent flower.
