Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to an ice making machine, and particularly to an ice making machine in which an ice making mechanism is mounted on an ice storage.

b. Conventional technology Conventionally, in ice making machines in which the ice making mechanism is mounted on the ice storage, a bottom plate was provided under the base plate that supports the ice making mechanism and the refrigeration device to prevent dust from adhering and to provide heat insulation. .

That is, as shown in FIG. 3, a bottom plate 6 constituting the ceiling of the ice storage is provided below the base plate 5 that supports the ice making mechanism, etc.
The ice discharge cylinder 3 has an opening 5b in the base plate 5 and an opening 6 in the bottom plate 6.
b, and is supported by placing or adhering the enlarged portion 3d on the base plate 5 and opening into the ice storage. A gasket 7 is provided at the open end of the bottom plate 6 to seal the gap between the outer surface 3C of the ice discharge tube 3 and the opening 6b in the bottom plate 6, thereby helping to prevent cold air from leaking and dust from entering.

c. Problems to be solved by the invention In the conventional ice making machine in which the ice making mechanism is mounted on the ice storage, the open end of the bottom plate and the lower end of the ice discharge tube are located on the same plane, so that ice is not discharged easily. Most of the water droplets from the ice that melts in the cylinder drip into the ice storage from the lower end of the ice discharge tube, but some of the water drops after wetting the gasket reach the bottom surface 6a of the bottom plate 6, that is, the ceiling of the ice storage. (See arrow 11 in Figure 3).

When these water droplets evaporate on the ceiling of the ice storage, they leave behind traces of impurity precipitation in that location (naturally, ice that melts easily is often made from water that contains many impurities). ),
It looks unhygienic as well.

However, in order to eliminate this drawback, extending the lower end of the ice ejection cylinder below the bottom plate and preventing water droplets from reaching the bottom of the bottom plate is difficult because the ice making mechanism is transported after the ice ejection cylinder is installed. In this case, a protruding portion is formed on the ice-making mechanism, which is undesirable as it becomes an obstacle during packaging and transportation.

This invention enables ice making without dripping water from melted ice onto the bottom of the bottom plate, and without any protruding parts from the bottom plate that would be an obstacle when packaging and transporting the ice making mechanism after the ice making mechanism is assembled with an ice ejector. The purpose is to provide a machine.

d Means for Solving the Problems In order to achieve the above objectives, the present invention includes an ice storage, an ice making mechanism placed on the ice storage via a bottom plate, and an ice making mechanism that is free of the ice making mechanism. In an ice maker comprising an ice discharge tube that opens into the ice storage through an outlet, a recess is provided in the bottom plate toward the ice making mechanism, and the ice discharge tube protrudes from an opening formed in the recess. In addition, the length of the protrusion should be the same as or smaller than the depth of the recess.

e Effect: A recess is provided on the bottom plate of the ice-making mechanism toward the ice-making mechanism, and the ice ejector is protruded from the opening formed in the recess, so water droplets generated by melting of ice inside the ice ejector are removed. The ice does not reach the bottom of the bottom plate, and all of it falls into the ice storage from the lower end of the ice discharge tube, leaving no trace of precipitate after evaporation on the bottom of the bottom plate, that is, the ceiling of the ice storage. .

In addition, since the protruding length of the ice ejector is made equal to or smaller than the depth of the recess, the protruding portion can also prevent problems when packaging and transporting the ice making mechanism after incorporating the ice ejector into the ice making mechanism. It is easy to package and transport.

f. Embodiment Hereinafter, an embodiment of the present invention will be described with respect to an auger-type ice maker shown in the figure.

In FIG. 1, 1 is a frozen casing constituting an ice making mechanism, 2 is a discharge port, 3 is an ice discharge tube, 3a is an inner surface of the ice discharge tube 3, 3b is its lower end, 4 is an ice storage box,
4a is a heat insulating wall, 5 is a base plate, 5a is a side wall of the base plate 5,
6 is a bottom plate.

The ice-making mechanism including the frozen casing 1 is supported on a base plate 5, and placed on the heat insulating wall 4a of the ice storage 4 via a bottom plate 6 provided below. Ice produced within the freezing casing 1 is discharged into the ice storage 4 through the discharge port 2 and the ice discharge cylinder 3.

In the case of ice made from water with a high concentration of impurities, it melts easily and scatters inside the ice discharge tube 3.
may wet the inner surface 3a and form water droplets.

These water droplets fall down the inner surface 3a of the ice discharge cylinder 3 due to their own weight, and drip into the ice storage 4 from the lower end 3b of the ice discharge cylinder 3. Some of the water that dripped into the ice storage 4 adheres to the ice, but the majority of the water drips into the ice storage 4.
is discharged from the drain port (not shown).

To explain in more detail with reference to FIG. 2, the ice discharge tube 3a is supported by its enlarged portion 3d on the surface of the edge of the opening 5b of the base plate 5,
The space between the bottom plate 6 and the opening 6b is sealed by a gasket 7 provided in the bottom plate 6. A recess 8 recessed toward the ice-making mechanism side is formed in the bottom plate 6, and the recess 8
An opening 6b is formed inside. Note that the recess 8
is formed at the same time as the opening 6b is formed as a punched hole, and the recess depth L is the same as or somewhat larger than the protrusion length h of the protrusion. The protrusion length h from the recess 8 is necessary to prevent water droplets that have descended from the inner surface 3a of the ice discharge tube 3 from traveling along the lower end 3b to the outer surface 3C, and is required to be approximately several mm.

The water droplets that descend under their own weight on the inner surface 3a of the ice discharge tube 3 reliably fall into the ice storage 4 from the lower end 3b of the ice discharge tube 3 (see arrow 11).

Therefore, since there are no water droplets traveling to the bottom surface 6a of the bottom plate 6, no traces of precipitates formed by evaporation of water droplets are left on the bottom surface 6a. In addition, since the protruding length h of the ice ejection cylinder 3 is made equal to or smaller than the recess depth L of the recess 8, even if the ice ejection cylinder 3 is integrated into the ice making mechanism, there is no protruding part and the packaging and easy to transport.

Note that the planar shape of the recess 8 is preferably adapted to the cross-sectional shape of the ice discharge cylinder 3.

g. Effects of the invention According to the invention, a recess is provided in the bottom plate of the ice-making mechanism, and the ice ejector is made to protrude from the opening formed in the recess, and the length of the protrusion is equal to the recess of the recess. Since the depth is the same as or smaller than the depth, the water droplets inside the ice ejector do not reach the bottom of the bottom plate, that is, the ceiling of the ice storage, and all of the water drops fall into the ice storage from the lower end of the ice ejector and reach the ceiling of the ice storage. The ice-making mechanism does not leave any traces of precipitates caused by evaporation of the water supply, and no protruding parts are formed when the ice-discharging cylinder is incorporated into the ice-making mechanism, making it easy to package and transport the ice-making mechanism.
