Abstract: A small steam generator uses a cylindrical steam generation vessel having a steam generation portion formed to store an amount of water for generating steam and a steam passage portion formed on the upper end of the steam generation portion for spouting steam generated in the steam generation portion. A heater element is disposed within the steam generation vessel, and an induction heating coil is wound around the periphery of the steam generation vessel for energizing the heater element. The heater element is energized by supply of electric power to the heating coil so that steam generated by boiling of the water in the steam generation portion spouts upward from the steam passage.

Abstract: The subject of the present invention is to provide a steam generator constructed small in size. A steam generator 20 of the present invention is composed of a cylindrical steam generation vessel 30 having a steam generation portion 31 formed to store an amount of water for generating steam and a steam passage 32 formed on the upper end of the steam generation portion for spouting steam generated in the steam generation portion, a heater element 40 disposed within the steam generation vessel 30, and an induction heating coil wound around the periphery of the steam generation vessel 30 for energizing the heater element. The heater element 40 is energized by supply of electric power to the heating coil so that steam generated by boiling of the water in the steam generation portion spouts upward from the steam passage.

Abstract: An ice making section of a stream down type ice making machine for enabling easy cleaning between a pair of ice making plates and for enabling individual replacement of every component, thereby reducing the cost of replacement. A plurality of mounting members 16 are provided on an evaporation pipe 14 in parallel being separated at a predetermined interval in the extending direction of a linear part 14. Each of parts to be engaged 16b, 16b is formed at an open end of each mounting member 16. At an open end of each ice making member 18 formed into generally U-shaped by bending, each engagement part 22d which is engageable with and disengageable from the part to be engaged 16b is formed. By assembling the ice making member 18 between the mounting members 16, 16 adjacent to each other so as to engage each engagement part 22d with the corresponding part to be engaged 16b, a first ice making section is configured so that the pair of ice making plates are oppositely arranged across the evaporation pipe 14.

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: There are disclosed an automatic ice maker and its operating method. A pair of ice making chambers are longitudinally arranged to face each other across a cooling tube. A plurality of ice making compartments are defined in each ice making chamber. On the open side of the ice making chamber, water trays for opening/closing the ice making chamber are arranged in parallel to be laterally moved. The water tray is moved between an ice making position for closing the ice making chamber and an open position for opening the ice making chamber by an opening/closing device. When a deicing operation is carried out, the water tray is laterally moved to the open position while ice cubes are frozen thereto to remove the ice cubes from the ice making compartments, and the cubes are deiced from the water tray in this open position.
