ものである。[Detailed description of the invention] The present invention relates to an auger-type ice maker, and in particular, a geared motor and a pressing head used when compressing sherbet-shaped ice to change the quality of ice into bar-shaped ice in the ice compression passage in the pressing head. The present invention relates to new improvements to reduce the load on the bearings of the machines and prevent abnormal noises, failures, etc.

故障等の原因となつていた。 In this type of auger ice maker that has been used in the past, in order to obtain clear and hard ice,
Improvements have been made to the shape of the press head, the structure of the screw, etc., and the area ratio of the inlet and outlet surfaces of the press head has increased, increasing the load on the geared motor and bearings and increasing their wear. This was causing the malfunction. In other words, when the area ratio of the inlet surface and the outlet surface at the press head exceeds 60%, the load on the screw increases periodically during ice-making operation for a short period of time as a sign of ice clogging. This phenomenon occurs because when the resistance at the pushing head is greater than the force that sends out the ice, the density of the ice increases and the ice transmits a force greater than the resistance, causing the ice to be pushed out rapidly. This is considered to occur. The load is at its maximum just before the ice is pushed out of the pressing head, and when the resistance increases and becomes greater than the shearing force of the icicle, a slippery surface forms at the end of the screw blade, resulting in an ice jam. It becomes impossible to make ice. This phenomenon occurs when ice with a high content of calcium, magnesium, silica, etc. is used as ice-making water, and as the ice-making operation progresses, the content of these substances in the ice-making water in the frozen casing increases
This is a six-fold increase, so it is extremely likely to occur, and repeated load fluctuations accelerate wear on bearings, etc., which in turn significantly shortens the life of the ice maker, as well as causing abnormal noise and noise.
This was causing malfunctions, etc.

荷や異音発生を軽減するようにした構成である。 The purpose of the present invention is to provide an extremely effective means for quickly eliminating the above-mentioned drawbacks.In particular, a heater is provided on the upper part of the outer periphery of the press head, and the heater is continuously energized during ice-making operation. By connecting it to an electric circuit that heats the ice generated at the outlet of the compression passage in the press head and slightly softening or melting it, it reduces the load on the drive system and the generation of abnormal noise when compressing ice in the press head. This is a configuration designed to reduce this.

圧頭より排出させるものである。 In the above configuration, the case where the auger type ice maker according to the present invention is operated is as follows.
First, when the power is turned on, water supply starts, and when the float switch FS detects a predetermined amount, water supply is complete, and relay X 1 is energized, relay X 1 becomes self-holding state, and the contact of thermal timer TM 2 is turned on, which lasts for a predetermined time. Afterwards, the magnetic contactor MS operates, closing its contacts and starting ice-making operation. Therefore, while driving the geared motor 12 and detecting an appropriate temperature with the thermostat Th, the electrical circuit consisting of the contacts of the magnetic contactor MS, the thermostat Th, and the fuse F in series, which is constantly energized during ice making operation, is operated. While the connected heater 11 starts operating, the contacts of the thermal timer TM 1 are delayed to the contacts of the thermal timer TM 2 , and the fan motor FM and compressor CM start operating. In this way, when ice making is started, the shearbed-shaped ice that has grown on the inner surface of the frozen casing and is scraped off by the screw blade 2 is fed into the ice compression passage 6 of the pressing head 4 and compressed into bar-shaped ice, and then The ice is cut by the cutter 8 and sent to the discharge passage in the ice discharge cover 9, but in this case, the heater 1 on the upper outer periphery of the pressing head 4
1, it is possible to heat the ice near the exit of the ice compression passage to slightly soften or melt it, thereby reducing the load on the geared motor and the bearing portion of the pressing head during ice compression. Further, the parallel surface portion 7 of the ice compression passage 6
Heater 1 is installed on the outer periphery of frozen casing 1 corresponding to
1 is attached, the part of the pressing head 4 where the compression resistance is greatest is formed in the parallel surface part 7 to prevent it from being compressed, and the temperature of the part where the resistance is the greatest is heated intensively. is raised slightly to soften or melt the contact portion of the compressed ice bar, and the ice bar is discharged from the pressing head without an unreasonable load.

In addition, the upper end of the ice compression passage of the pressing head, which is subjected to the maximum load when being pushed out from the pressing head, is made into a parallel surface section, and the parallel surface section is heated intensively, which further promotes the above effect and prevents ice from clogging. It is possible to reliably prevent the deterioration of ice quality due to Furthermore, the reliability of each component is significantly increased, and at the same time, damage to the ice making mechanism can be extremely effectively prevented, thereby greatly improving the reliability of the auger ice maker.
