Abstract: PURPOSE:To shorten the sales time by preventing an ice from scattering while temporarily receiving a cake of ice and integrally putting them in a cup. CONSTITUTION:An ice 12 is temporarily stored in a bucket 1 so as to finish the transmission of the ice 12 from an ice maker 2 in advance until a cup 10 reaches the prescribed position of feeding ice. When a cup 10 with beverage is set to an ice feeding state. The controller turns on a solenoid 5 and pulls in a plunger 5a. Accordingly, the bucket 1 rotates around a shaft 4 by a link mechanism 7. The bucket 1 stops when the plunger 4a of the solenoid 4 is housed, and the ice 12 held in the bucket 1 is thrown in the cup 10. In the bucket 1, the center of gravity G in the ice feeding position is set to the lower side of the bucket 1 than the lines drawn horizontally and vertically from a shaft 4. When the solenoid 5 is turned off again, it returns to the waiting state by weight.

Abstract: PURPOSE:To prevent a reduction in heating capability caused by an excessive increasing of discharging temperature or a reduction in suction pressure even under an excessive operating state by a method wherein a controlling interval of a controller for an outdoor electric expansion valve is longer than a controlling interval of an inverter controller. CONSTITUTION:During a heating operation, a condensing pressure is detected. When the condensing pressure is higher than a predetermined pressure, a variable capability compressor 2 is instructed from the inverter controller 13 so as to instruct it to decrease an operating frequency and if the pressure is lower, it is instructed to increase. This control is repeated for every one minute. A piping temperature between the indoor device 7 and an outdoor electric expansion valve 5 is detected. If it is higher than a predetermined temperature, an instruction to close by a predetermined degree of opening in respect to the expansion valve 5 from an outdoor electric expansion valve control device 15' and if it is lower, it is instructed to open. This control is repeated for every two minutes. That is, a condensing pressure with a fast responding speed is approached to a set value with a short interval and at the same time a slow responding sub-cooled degree is approached gradually to a set value at a long interval, resulting in that it is possible to prevent over-increasing of discharging temperature under an excessive operation state or a reduction in suction pressure.

Abstract: PURPOSE:To equalize cooling/heating rising performance and cooling/heating capacity of each of a plurality of room units arranged on different floors by providing a refrigerant circulation volume adjusting means between an outdoor side expansion valve and a room side expansion valve of the plurality of room units. CONSTITUTION:Two room units 7a and 14 are connected to an outdoor unit 1, the room unit 7a arranged on an upper floor and the room unit 14 on a lower floor, and a refrigerant circulation volume adjusting means 15 of the room unit 14 is placed between a room side expansion valve 8b and an outdoor side expansion valve 5 and consists of a capillary tube 16 and a check valve 17. During cooling operation, in the room unit 14 on the lower floor, as refrigerant is made to flow by the refrigerant circulation volume adjusting means 15 through the capillary tube 16 having a resistance equal to a pressure dropdown of a height difference of 10m, the volumes of the refrigerant flowing into the room units 7a and 14, though positioned at different height, are the same. During heating operation, as the refrigerant is protected by the refrigerant circulation volume adjusting means 15 from being decreased in the pressure, and therefore no pressure loss occurs. Accordingly, the cooling/heating rising performance and cooling/heating capacity of the room units 7a and 14 can be maintained equally.

Abstract: PURPOSE:To obviate the electric connection between a door main body and a box body which supports the door main body by a method wherein left and right latch displacement limiting means, provided on the box body, are controlled so that a pin at the side of the supporting shaft of the door main body can not be released from the groove of the box body. CONSTITUTION:A box body 3 is provided with a latch displacement limiting means 10, limiting the displacement of a latch 9 and preventing a pin 2 from being released from a groove 8, while the latch displacement control means 10 is controlled based on the detecting result of left and right door main body opening and closing operation detecting means 11. When the left side surface of the door main body 1 is gripped and pulled, for example, the latch 9 is pivoted about a rod 15 in accordance with the movement of the left side pin 2, the lever of the left side latch displacement detecting switch 21 is abutted against the crest of the cam unit 17 of the latch 9 and the switch 21 is thrown. When a left side solenoid 28 is conducted thereafter, a left side lock plate 23 is pivoted about another rod 24 and the stopper surface 25 of the lock plate 23 comes to a position not precluding the advancing passage of the lock pin 18 of the left side latch 9. When the door main body is opened further, the retension of the left side pin 2, which is effected by the latch 9, is released and the door main body may be opened from the left side thereof about a right side pin 2.

Abstract: PURPOSE:To shorten a drink blending time by preparing a nozzle aperture area varying means and connecting an ice feeding line to a nozzle. CONSTITUTION:When a powder material is injected into a cup 8c by a vending command and the cup 8c is set up on the lower part of the nozzle 8, hot water pressured through a pressured hot water feeding line 9c is injected from the nozzle 8 into the cup 8c. At that time, a needle valve 11 is set up on a position where a gap between the outer face of the valve 11 and the inner face of an aperture part 8a is reduced by a driving means 13, the projection shape of injection is like an approximate ring and the injection water is radially discharged. Since a large injection area can be obtained, the efficiency of stirring is improved. Since dilution water and ice can be simultaneously injected from the same nozzle 8 in the case of producing a cold drink, a tasty cold drink reducing a temperature difference between the upper and lower parts of a cup can be obtained.
