Description

[Detailed Description of the Invention] This invention relates to an auger ice maker, and in particular, to a novel improvement for constantly dripping and draining a small amount of ice-making water during ice-making operation.

This type of auger ice maker that has been used in the past is mechanically capable of continuous ice making and provides efficient ice making operation, but on the other hand, impurities contained in the ice making water are concentrated and the cylinder and screw bearings are damaged. This can lead to a decrease in ice-making capacity, trouble with bearings, and even have a negative impact on water quality.One way to eliminate these conventional drawbacks is to install a solenoid valve when the water storage switch is activated. An activated and drained configuration was used.

However, in such a conventional configuration, the drainage solenoid valve does not operate unless the water storage switch is operated, so phenomena such as deterioration of water quality still continue, and the drainage solenoid valve and control circuit etc. This led to an increase in costs as it became necessary.

Furthermore, impurities such as silica and calcium contained in the ice-making water tend to concentrate inside the cylinder and adhere to the walls of the cylinder, making it difficult to remove the impurities adhering to the walls only by normal drainage operations.

The purpose of this invention was to provide an extremely effective means to quickly eliminate the above-mentioned drawbacks of the conventional technology.In particular, the water supply pipe and drainage pipe were installed at the bottom of the cylindrical casing that contained part of the auger screw. By installing a pipe and arranging this drainage pipe so as to extend tangentially on the downstream side with respect to the direction of rotation of a part of the auger screw, the impurities are constantly pushed out along with the ice-making water by the screw teeth. It is characterized by a structure in which the water is discharged through a drainage pipe, and a transparent pipe is provided at the tip of the drainage pipe.

Hereinafter, a preferred embodiment of the auger ice maker according to this invention will be described in detail with reference to the drawings. In the drawings, the reference numeral 1 indicates a cylindrical casing, and inside the casing 1 there is a bearing portion 2. An auger screw portion 3 is provided which is rotatably held by.

A cooling pipe 4 is wound around the outside of the casing 1 to guide a refrigerant supplied by a compressor CM shown in FIG. 3 and to cool the casing 1.

This auger screw part 3 is configured to be rotationally driven via a spline part 6 by a drive morph 5 provided at the lower part of the casing 1.

Next, at the lower end of this casing 1, a water supply pipe section 7 and a drainage pipe section 8 are arranged in substantially the same plane position, and this water supply pipe section 7 is connected to the water supply control valve W in FIG.
Connected to V.

Furthermore, this drainage pipe 8 is specially provided in this invention, and as is clear from FIG.
It is arranged tangentially on the downstream side with respect to the direction of rotation of the auger screw part 3.

This drainage pipe section 8 includes a transparent pipe 9 and a nozzle 1.
0 is provided for each.

Note that since ice-making water is constantly drained from the drain pipe section 8 while the auger ice maker is in operation, the inner diameter of the drain pipe section 8 may be made smaller than the water supply pipe section 7.

To briefly explain the electrical wiring diagram shown in Fig. 3, the compressor CM is provided with a cooling fan FM, and the normally closed contact of the control relay X2 and the water level switch S3 are connected in series to the water supply control valve Wv. The water supply side valve is configured to close when both of the normally closed contacts of the water level switch S3 and the control relay X2 are closed.

The gear motor 5 is also provided with timers TM1 and TM2 that operate in conjunction with a water storage detection switch S1 of a water tank (not shown), and the water storage detection switch S1 is also connected to a control relay X2.

Next, we will discuss the case of operating the auger-type ice maker according to this invention with the above configuration.
When the ice is cooled, the shaved ice is successively discharged from the tip of the auger screw part 3, and the ice making water is continuously released from the water supply pipe part 7 by turning the water supply control valve W■. will be sent.

When the ice-making operation is performed in this manner, a portion of the ice-making water supplied into the casing 1 from the water supply pipe section 7 is guided to the outside via the drain pipe 8, and is passed through the transparent pipe 9 and the nozzle 10. The water will be completely drained.

In this case, the drain pipe section 8 is provided in the casing 1 so as to extend tangentially on the downstream side with respect to the rotational direction (counterclockwise in FIG. 2) of the auger screw section 3, so that the water supply pipe section 7 Compared to the case where the drain pipe 8 is installed at right angles to the casing 1, the cross-sectional area of the inlet of the drain pipe 8 becomes much wider, and the impurities inside the casing 1 and on its inner wall are removed by the rotation of the auger screw part 3. The ice making water can be effectively pushed out from the entrance of the drain pipe section 8 whose area has been enlarged as shown in FIG. You can know the state of dirt.

Furthermore, if the water storage tank is full of ice, the water storage detection switch S
1 turns ON, timer TM1. TM2 and control relay X2 operate, driving motor 5 and compressor CM.
are stopped after a predetermined time, and the water supply control valve W■
This closes the water supply pipe 7 and stops the water supply from the water supply pipe 7.

Since the auger-type ice maker of this invention has the above-mentioned configuration and function, the concentrated residual water of the ice-making water that has accumulated in the casing is constantly drained, which dramatically improves the hygiene level inside the casing. In addition, by looking at the dirt on the inner surface of the transparent pipe, it is possible to infer dirt inside the freezer casing, and it is also possible to predict when it is time to disassemble and clean the inside of the casing, thereby preventing problems in advance. can do.

Furthermore, by closing the water supply control □□ valve when the water storage detection switch is activated, it has great effects such as making it possible to replace all the ice-making water in the cylinder (casing). It has a great effect of preventing accidents caused by freezing and bursting of cylinders, and achieves its purpose at low cost and without requiring any manpower.

In addition, since the structure is such that concentrated residual water from ice-making water is constantly discharged from the drainage pipe at the bottom of the casing, the temperature of the discharged water is low, and it can be used by head or pressurization for drinking or cooling. possible and economical to operate.

Therefore, by employing the device according to this invention, service, maintenance and inspection become easier, which further contributes to the spread of this type of device.
