Description

[Detailed description of the invention] a. Industrial application field The present invention relates to an ice storage device with an ice discharge device for storing ice cubes, etc., and extracting and supplying the stored ice from a discharge port as needed, and particularly relates to an ice storage device equipped with an ice discharge device for storing ice cubes, etc. This invention relates to improvements to ice discharge passages.

b. Prior Art A conventional ice storage device with an ice discharge device will be described with reference to FIG. 7 (plan view), FIG. 8 (front view), and FIG. 9 (side view). A storage chamber or stocker 1 is provided with an ice agitator 3 driven by a motor 4, at the bottom of which two agitator arms 2 extend radially outward. The agitator arm 2 uses ice cubes, etc. (hereinafter abbreviated as ice) stored in the stocker 1.
is pushed out to the bottom side receiving part of the ice discharge auger 5.

The ice discharge auger 5 extends obliquely from the bottom of the stocker 1 toward the ice discharge port 6 above the front of the main body.
When the push button 7 on the front panel 8 is pressed, it is rotated by the drive motor 14 and the outlet 2
Ice is fed by spiral motion to a container etc. placed at zero. The portion between the upper and lower ends of the ice discharge auger 5 is surrounded by an inclined gutter 18 having a substantially semicircular cross section, and the ice is removed by the cooperative action of the ice guide 9 attached thereto and the ice discharge auger 5. The ice rises from the bottom of the stocker 1 along the ice discharge auger 5 through the inclined gutter 18. The rising ice is pushed out from there to the ice discharge port 6,
It is dropped and supplied into a container, etc.

c. Problems to be solved by the invention As mentioned above, the ice in the stocker 1 is sent to the lower entrance of the inclined gutter 18 by the ice agitator 3, but in order to ensure the feeding, The distance between the rotating outer circumference of the agitator arm 2 and the inclined gutter 18 is reduced. Therefore, the ice caught between the agitator arm 2 and the partition wall of the inclined gutter 18 is easily crushed. In this way, as the amount of crushed ice increases, the rear wall 26 of the stocker 1 and the rear wall 26 of the inclined gutter 18 may be linearly connected on the same plane, and the crushed ice will be in front of the wall. It is being accumulated. In other words, crushed ice accumulates in the substantially triangular area surrounded by the turning trajectory of the agitator arm 2, the inclined gutter 18, and the aforementioned rear wall 26, and is no longer fed to the ice discharge auger 5. That is, there was a problem in that the ice in the stocker 1 simply rotates within the stocker 1 due to the rotation of the agitator arm 2, and is not discharged.

d Means for solving the problem The present invention was made to solve the above-mentioned problem, and even if there is a large amount of crushed ice in the storage room, it will not accumulate in the ice passage to the ice discharge auger and will ensure that The object of the present invention is to provide an ice storage device with an ice discharge device capable of discharging and supplying ice.

For this purpose, the ice storage device of the present invention includes a storage chamber having a substantially cylindrical peripheral wall, an ice agitator disposed therein, and an ice discharge auger disposed inside and adjacent to the storage chamber. and a sloped gutter formed therein. and a vertical rear wall that is perpendicular to a vertical plane containing the longitudinal axes of the ice discharge auger and the sloped trough and that defines an ice passage to the ice discharge auger and that forms part of the peripheral wall of the storage chamber and is connected to the agitator arm. It intersects the vertical tangential wall along the turning trajectory at an obtuse angle (90°<ψ<180°).

e Effect As mentioned above, in the ice storage device of the present invention, the delivery guide wall for the ice sent to the lower part of the ice delivery auger is connected to the tangential wall of the storage chamber, which intersects at an obtuse angle in the horizontal plane, and the inclined gutter. It is defined by the rear wall of the That is, the rear wall of the inclined gutter has a shape that is moved toward the front outlet side compared to the conventional one, and a triangular ice retention area is not substantially formed.

Upon demand for ice supply, the ice agitator and ice discharge auger rotate together. The ice in the storage chamber is pushed by an agitator arm, guided by a delivery guide wall consisting of a tangential wall and a rear wall, and passes over the partition wall of the inclined trough and enters between the spiral blades of the ice discharge auger. . This ice is carried up on the inclined gutter by the rotation of the ice discharge auger, and is supplied from the upper outlet of the gutter through the ice discharge port to a container or the like.
