ることがあった。BACKGROUND OF THE INVENTION An auger type ice making machine has a refrigerating casing which is a vertically long cylindrical member, and an evaporator which is a part of a refrigerating circuit is wound around the outer peripheral surface thereof, and a spiral blade is provided inside. An auger having a. Ice-making water is supplied to the inside of the freezing casing, and the ice that has grown on the inner peripheral surface of the freezing casing is scraped off by the rotation of this spiral blade and becomes flaky ice by the spiral action. It is transported upward. An ice transport passage communicating with the ice storage is connected to the upper portion of the freezing casing, optionally via a pressing head having an ice compression passage, so that the ice produced is in the form of flakes or, if desired, ice compressed. The ice particles are compressed in the passage and finally conveyed to the ice storage through the ice conveying passage. The ice storage is usually provided with an ice storage detection switch that detects when the ice storage is full of conveyed ice and stops the rotation of the auger. In the above-mentioned auger type ice making machine, for some reason,
If the ice storage detection switch does not operate normally, even if the ice storage is full, the auger may not continue to rotate and may continue to be conveyed. The auger and the drive system (motor, etc.) that drives it are overloaded, and in some cases the internal pressure of the ice transport passage increases due to ice clogging, so that the ice transport passage communicating with the ice storage and the top of the freezing casing There was a case that the connection part of was damaged.

があった。In order to solve such a problem, for example,
In Japanese Patent Laid-Open No. 2-293571, a pair of electrode plates is provided in a passage for transporting ice to an ice storage, and when the above-mentioned ice clogging occurs, there is ice between the electrode plates, so that the capacitance thereof is increased. There is disclosed an auger type ice making machine which controls the drive of the auger by utilizing the change of the temperature. Also, the actual Kaisho 61-19
Japanese Patent No. 5276 discloses an auger type ice making machine in which an operating plate is arranged in a passage for transporting ice to an ice storage and a micro switch is operated through the operating plate when an ice jam occurs to stop the driving. Machine is disclosed. In addition, Japanese Examined Sho 56-
According to Japanese Patent No. 40258, one or more through holes are formed in a member for promoting the transportation of ice in a passage for transporting the ice to an ice storage, and a detection plate for activating a micro switch is provided above the through hole. When the ice blockage occurs, flaky ice passes through the through hole, and the micro switch is operated via the detection plate to confirm the occurrence of the ice blockage. Is disclosed. However, the above ice-making machine structure and the like have the following effects, although they have the corresponding effects. That is, JP-A-2
According to the Japanese Patent Laid-Open No. 2933571, not only when the space between the electrode plates is filled with only ice, but also when the space between the electrode plates is filled with ice and water droplets, it may be mistakenly recognized that ice clogging has occurred in the ice transport passage. Therefore, the drive of the auger is practically stopped until there is no risk of ice clogging. Further, Japanese Utility Model Publication No. 61-195276 and Japanese Patent Publication No. 56-4025.
In the case of the No. 8 publication, when the ice is clogged, the push-up pressure of the ice acting on the actuation plate (the detection plate in the latter case) is not uniform, so the micro switch may not operate properly.

ることを目的とする。In this drawer type auger type ice making machine, since the ice making mechanism and the ice carrying passage are not fixed to the main body, the ice carrying passage is pulled out at the time of assembly or transportation or due to ice clogging. There was a possibility of slipping in the direction and coming off the ice storage. However, the actual fairness 4 mentioned above
Since the conventional technique described in Japanese Patent Publication No. 51331 does not have any detection function for displacement in the pull-out direction,
Even if this conventional technology is applied to a drawer type auger type ice making machine, the ice making operation is restarted even with the above-mentioned misalignment, and ice or water leaks from the gap between the ice transport passage and the ice storage, Alternatively, since the positional relationship between the operating means and the switch means in the ice blockage detection device is still misaligned, it is not possible to accurately detect the ice blockage during the next ice making operation, and the part that can be pulled out by the pressure of the blocked ice May fall. Therefore, the present invention prevents the ice making operation from starting without the ice transport passage and the ice storage being normally connected, and the positional relationship between the ice transport passage and the ice storage is not limited to the connecting direction, It is an object of the present invention to provide a drawer-type auger-type ice maker that can detect the pull-out direction.

00 circuit diagram. First, when the drawer type auger type ice maker is connected to a power source and the power switch 201 is turned on, the water supply valve 17 is energized through the relay contact X 32 and the relay contact X 52 , and the water supply valve 17 opens. At this time, it is assumed that the ice storage detection device 7 is closed because the ice storage 3 is not full of ice, and the switch S 2 indicated by reference numeral 107 is open. By opening the water supply valve 17, water is supplied to the ice making water tank 21 from the external water supply system through the water conduit 19. For this water supply, the water level in the ice making water tank 21 rises and the float switch 2
It continues until the upper limit water level detection switch 205b of 05 operates. When the upper limit water level detection switch 205b is closed by detecting the upper limit water level, the relay X 3 are being energized energized. As a result, the normally closed relay contact X 32 opens and the water supply valve 17
Is turned off and the valve is closed. When the relay X 3 is energized and excited, the relay X 1 is first excited, and then the relay X 2 is excited, whereby the geared motor 37 and the refrigerant compressor 207 are activated in that order, and the ice making operation is started for the first time. .

When the compressor 207 and the fan motor 209 are activated and the ice making operation is started, the ice making water in the ice making water tank 21 is supplied into the freezing casing 27 through the water supply pipe 25 and is cooled by the cooling pipe 33 wound around the outer peripheral surface. The heat is taken away, and the inner peripheral surface of the frozen casing 27 gradually freezes. At the same time, the spiral blade 3 of the auger 29 rotated by the geared motor 37
The ice on the inner peripheral surface is scraped off by 1 to form flaky ice, which is sent upward. And the upper pressing head 39
The ice compressed by is cut into a predetermined size by the cutter 41 and is stored in the ice storage 3 through the ice transport passage 15. When replenishment of the ice making water to the refrigeration casing 27 is continued, it lowers the water level in the tank 21 (FIG. 3), the lower limit water level detection switch 205a is operated, the relay X 3 which has been self-holding is demagnetized, the relay Contact X 32 closes. Then, the water supply valve 17 is opened again to supply water to the ice making water tank 21 for the second time. Ice making water tank 21
When the water level in the ice-making water tank 21 rises to the upper limit water level due to the water supply to the upper limit water level detection switch 205b, the circuit closes. As a result, the relay X 3 is re-energized and the ice making operation starts again.

However, when the ice conveyed is increased, the height of the ice accumulated in the ice storage 3 increases. When the ice storage compartment 3 is gradually raised and the inside of the ice storage compartment 3 is filled with ice, it contacts the operation lever 47 shown in FIG. 5 to operate the ice storage detection device 7. The above-mentioned operation corresponds to the opening of the switch S 1 indicated by reference numeral 7 in FIG. When the switch S 1 is opened, the relay X 3 is de-energized and demagnetized, and the geared motor 37 is further stopped, whereby the ice making operation is interrupted.
