Abstract: In an ice making plate where a plurality of ice making regions are formed in the vertical direction, a projecting portion having a lateral width B smaller than a lateral width A of the ice making regions is formed between adjacent ice making regions. At least one non-projecting portion or area is defined at least one side of the projecting portion and located between adjacent ice making regions. Most of the ice growth is restricted by an upper surface portion and a lower surface portion of the projecting portion, and the ice is thereby partially prevented from connecting to the ice formed in the adjacent ice making region. However, a part of the ice grows in the at least one non-projecting portion or area, and partially connected ice is formed by the connection of the ice formed in the non-projecting portion or area to the ice grown in the adjacent ice making region. The partially connected ice is dropped as an integrated whole from the ice making plate.

Abstract: A cooling unit wherein devices are divided so as to be installed in each of an outdoor unit and indoor unit, for downsizing the indoor unit and reducing its pipe-line cost. The cooling unit disposes a compressor, a condenser and a liquid receiver R in the outdoor unit, and disposes an expansion means and an evaporator in the indoor unit. The outdoor unit comprises a first bypass pipe closed by a first bypass valve so as to open/close freely. The indoor unit comprises a second bypass pipe, which is closed by a second bypass valve so as to open/close freely. The units are connected by a liquid pipe used as a supply line for refrigerant or hot gas by selecting a refrigerant supply line among the bypass valves and the open/close valves, and by a gas pipe communicating the evaporator to the compressor.

Abstract: Multiple ice making is determined according to a time needed for an ice making step or a change in time in which a refrigerant temperature drops. An ice making machine alternately repeats an ice making step of cooling ice making plates 10 and 10 where an evaporation pipe 14 connected to a refrigeration system 12 by circulatively supplying a refrigerant to the evaporation pipe 14, and producing lumps of ice M by circulatively supplying ice making water in an ice-making-water tank 22, and a deicing step of separating the lumps of ice M produced at the ice making plates 10 and 10. When the ice making step at which the time needed from the start of the ice making step to the end thereof becomes shorter than a normal ice making time is consecutively detected by a predetermined number of times, it is decided that multiple ice making has occurred and the ice making machine is stopped.

Abstract: An electrolytic ion-water production apparatus in which purified water without residual chlorine is electrolyzed to produce alkaline-ion water without any chloride smell of lime in use of the apparatus, and in which a mixture of purified water treated by a water purifier and tap water containing residual chlorine is electrolyzed to produce alkaline-ion water containing sodium hypochlorous acid (NaOCl) of low concentration and to retain the produced alkaline-ion water in an introduction passage for reliably preventing propagation of microbes.

Abstract: In external unit 19, three-way valve 25 provided downstream of CPR 23 enables a switching connection between CPR 23 and branch line 21A of first bypass line 21 with respect to liquid line 18 A. In internal unit 20, second bypass line 27 connects inlet side of receiver 13 and inlet side of evaporator 16, and open/close valve 28 is provided along second bypass line 27. At de-icing, three-way valve 25 switches to first bypass line 21 side and open/close valve 28 opens. There upon, hot gas from compressor 11 circulates from first bypass line 21 to liquid line 18A to enter evaporator 16 through second bypass line 27 while squeezing out liquid refrigerant. Evaporator 16 is heated by manifest heat of introduced hot gas, and when the internal pressure of vaporator 16 rises to a condensation temperature over 0° C., de-icing is performed efficiently by manifest heat plus latent heat.

Abstract: When refrigerant shortage has occurred, a failsafe operation, for example, for stopping an ice-making operation is carried out to thereby suppress wasteful electric power consumption and prevent an ice-making section and a compressor from being damaged. An ice-making machine alternately and repeatedly carries out the ice-making operation for producing ice blocks (M) by cooling an ice-making section (10) on which is disposed an evaporator (14) connected to a refrigeration system (12), by supplying refrigerant to the evaporator (14) for circulation, and deicing the operation for causing the ice blocks (M) produced on the ice-making section (10) to be released therefrom.
