Abstract: An indoor unit of an air conditioner includes an indoor heat exchanger, a body, a centrifugal fan, and a shutter. A plurality of discharge passages for discharging air that has passed through the indoor heat exchanger is formed in the body. The centrifugal fan generates a flow of air that passes through the indoor heat exchanger and is blown out of the discharge passages. The shutter is provided to at least one discharge passage of the plurality of discharge passages. The shutter is kept in a closed state by the pressure of the air flow.

Abstract: Disclosed is an automatic ice maker which surely removes ice cubes from an ice-making unit and improves an ice-making efficiency. When the automatic ice maker starts a deicing operation, a hot gas is supplied to an evaporator and deicing water is supplied to the ice-making unit from a deicing water sprinkler to turn the frozen state at the frozen surfaces between the ice-making unit and ice cubes to a liquefaction state. When the deicing operation makes some progression and a temperature detecting unit detects that the temperature of the evaporator has reached a set temperature, a circulation pump is driven after elapse of the first set temperature to supply ice-making water to the ice-making unit from an ice-making sprinkler, promoting further separation of the ice cubes.

Abstract: An auger type ice-making machine of the present invention comprises an ice-making cylinder which accommodates an auger rotatably in the interior thereof, an ice compression head which supports the upper end portion of the auger rotatably, and which is disposed in the upper portion of the ice-making cylinder, and a cast-in heater which is attached to the outer peripheral surface of an accommodating portion for the ice compression head of the ice-making cylinder. According to the present invention, the use of a cast-in heater enables heat to be reliably transmitted to the ice compression head, whereby the compressed ice can be melted and ice can be discharged smoothly.

Abstract: Three solid round bars are prepared as auger members, respectively as a main body member, an upper shaft member, and a lower shaft member. End surfaces of the members are coaxially joined together by friction welding. Turning machining is then performed by using a lathe, forming a helical blade, a spline, and the like. In addition, burnishing is performed on a corner portion that includes an outer circumferential edge of a joining surface where friction welding is performed, and another corner portion that includes an outer circumferential edge of another joining surface where friction welding is performed. The burnishing is performed by pressing a roller, which is freely rotatable about a roller support shaft center of a Superoll, toward the corner portions of the rotating auger. Roller burnishing may also be performed two times on the same location, with a predetermined time interval therebetween.

Abstract: A bypass passage is provided between a discharge pipe and a suction pipe of a compressor being a component of an auger type refrigeration circuit, for allowing a hot gas on the high-pressure side of the circuit to recirculate back to the low-pressure side. An electromagnetic valve is disposed on the bypass passage, and an ammeter is provided to a geared motor that drives an auger, which detects an overcurrent value indicative of an overload acting on the geared motor. In response to detection of an overcurrent value by the ammeter, the electromagnetic valve operates to allow a hot gas on the high-pressure side to be supplied to the low-pressure side through the bypass passage.

Abstract: An ice transporting assembly transports ice and includes a sleeve and a tapered auger. The sleeve defines a frusto-conically shaped channel with an inlet having an inlet diameter and an outlet having an outlet diameter less than the inlet diameter. The tapered auger is mounted for rotation within the sleeve and is sized and adapted for positional agreement with the frusto-conically shaped channel. Ice at the inlet is transported through the frusto-conically shaped channel and out of the outlet by rotating the tapered auger about a rotational axis. Another embodiment of the ice transporting assembly includes a reducing sleeve having an upstream conduit section with an upstream conduit diameter, a downstream conduit section with a downstream conduit diameter less than the upstream conduit diameter and a tapered conduit interposing the upstream conduit section and the downstream conduit section. The tapered conduit defines a tapered channel that receives the tapered auger in positional agreement.

Abstract: A method of preparing a heat exchanger provides a first surface(s) for contacting a first fluid and a second surface(s) for contacting a second fluid in order to exchange heat between the first and second fluids. At least one of the first and second surfaces has been exposed to shot from a shot blast machine in order to create pits and bumps in that surface. The pits and bumps create a more efficient heat transfer between the fluids.
