摘要： An icemaker having a means for bypassing a head pressure control valve thereof depending upon the ambient air temperature surrounding a remotely located condenser of the icemaker. The method and apparatus involve a first bypass conduit which is coupled to an outlet of the condenser upstream of the head pressure control valve and a first bypass valve disposed in the first bypass conduit. A second bypass conduit is in communication with an inlet of the condenser and also with the head pressure control valve. A second bypass valve is disposed in the second bypass conduit. A thermostat controls each of the bypass valves such that the first bypass valve is closed and the second bypass valve opened when the sensed ambient air temperature around the condenser is below a predetermined temperature, to thereby permit normal operation of the head pressure control valve. When the ambient air temperature is at or above the predetermined temperature, the first bypass valve is opened and the second bypass valve is closed, which causes condensed refrigerant to bypass the head pressure control valve completely. The above-described arrangement permits a high set point of the head pressure control to build more heat in a compressor during the freeze cycle of the icemaker when the condenser is experiencing low ambient air temperature conditions, and further allows the head pressure control valve to be bypassed entirely when the ambient air conditions are relatively high during the freeze cycle, and the head pressure control valve is therefore not needed.

摘要： An icemaker incorporating a hot gas bypass system for introducing a supplemental quantity of refrigerant from a condenser into a compressor of the icemaker during a harvest cycle. The system includes a harvest bypass valve disposed in a bypass conduit coupled between an input port of the compressor and the inlet of a remotely disposed condenser. The harvest bypass valve is opened by a system controller of the icemaker during a harvest cycle which allows refrigerant in the condenser to migrate back into the input port of the compressor during the harvest cycle. In this manner, it can be insured that a sufficient quantity of refrigerant is available to carry out the harvest cycle. The adding of a supplemental quantity of refrigerant is further accomplished through a single valve and does not add appreciably to the overall cost or complexity of the icemaker.

摘要： Ice making machine that uses PETD harvest technology, evaporators, ice molds and cooling system. One evaporator makes thin layers of ice that are laminated to form a larger ice piece. Other evaporators include an ice forming surface on a material that has good thermal conductivity for forming ice in a freeze mode and good electrical conductivity to serve as a resistive heater during a harvest mode. One evaporator has a plate and an array of freezing sites that extend above a surface thereof. Another evaporator has a plate that is divided into strips of good and poor thermal conductivity by. Another evaporator has a refrigerant tube that is sandwiched between a pair of corrugated sheets that have ice forming surfaces. Another evaporator has a waffle style pan that is constructed of a dielectric layer sandwiched between a pair of copper layers. Another evaporator forms an ice slab on an inclined flat surface, which after harvest is diced into cubes with a wire grid. A cooling system uses an evaporator to provide a cooling air to an ice mold to form ice and uses PETD energy to harvest the ice and defrost the evaporator.

摘要： A fault restart routine for an icemaker having a microprocessor-based system controller. The fault restart routine provides at least a limited number of attempts at automatically restarting the icemaker after a shutdown has occurred because of a detected fault condition. If the fault condition is not a water inlet fault, the routine waits a first predetermined period of time before attempting to restart the icemaker. If the fault is detected as being a water inlet fault, then the system controller waits for a second predetermined time period before restarting the icemaker. If after restarting the icemaker, the icemaker completes one complete cycle of operation (i.e., a complete FREEZE cycle and a complete HARVEST cycle), then the fault restart routine is exited and a previously generated fault code is cleared. If the icemaker does not full one complete cycle of operation within a predetermined number of restart tries, then the system controller generates a fault signal to the LED display and no further attempts at restarting the icemaker are made. The method alleviates the need for an operator or attendant to manually attempt to restart the icemaker in the event a fault condition occurs, which fault condition may only be temporary and/or due to environmental conditions such as power surges or brown-outs, and which does not require operator intervention. The method further protects the icemaker by automatically shutting down the icemaker if after the predetermined number of restart tries the fault condition is still present.
摘要翻译： 具有基于微处理器的系统控制器的制冰机的故障重启程序。 由于检测到的故障状况，故障重启程序至少提供了在关闭发生后自动重新启动制冰机的尝试次数。 如果故障条件不是进水口故障，则程序在尝试重新启动制冰机之前等待第一预定时间段。 如果检测到故障是进水故障，则系统控制器在重新启动制冰机之前等待第二预定时间段。 如果在重新启动制冰机后，制冰机完成一个完整的操作周期（即完全冻结循环和完整的HARVEST循环），则退出故障重启程序，并清除先前生成的故障代码。 如果制冰机在预定次数的重新启动尝试中没有完成一个完整的循环，则系统控制器向LED显示器产生故障信号，并且不再进行重新启动制冰机的尝试。 该方法减轻了操作员或服务员在发生故障情况的情况下手动尝试重新启动制冰机的需要，该故障状况可能仅仅是临时的和/或由于诸如电源浪涌或掉电的环境条件而导致的，以及哪个 不需要操作员干预。 如果在预定次数的重启尝试故障状态仍然存在之后，该方法还通过自动关闭制冰机来保护制冰机。

摘要： A refrigerator door hinge including a bracket connected to and extending forwardly from the face of the cabinet on the side to which the door opens. The bracket includes an upper horizontal plate supporting the door, and a lower horizontal plate with a threaded aperture which captures a threaded post of a foot. The bottom of the foot has a pad and during installation, the foot is rotated to lower the foot until the pad contacts the floor thereby providing adjustable height hinge support directly to the floor.
