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.

Automatic ice maker and its operating method

A beer pouring faucet provided in front of the server main body extends from the faucet main body and includes the operating lever which functions to change pouring of beer or the head by tilting the lever back and forth. The drive apparatus which is capable of automatic operation of the operating lever comprises a housing provided movably vertically with respect to the server main body a horizontally movable slider in forward and backward directions housed in the housing and a drive mechanism which moves the slider forward and backward, The drive apparatus is positioned at an operating position where the operating lever is inserted into the engagement hole of the slider or at a non-operating position where the operating lever is separated from the engagement hole by moving the housing vertically.

Beverage dispenser

A dishwashing machine the washing tub of which is opened at the top and is provided at its bottom portion with lower nozzle arms 51, 52. An upper opening of the washing tub is closed or opened by a door 20 which is provided with a top plate 21 of semi-circular cross-section and rotatable in its semi-circular direction along a pair of side walls of the washing tub. An upper nozzle arm is provided inside of the top plate at the central portion thereof. A water supply passage is provided along an internal surface of the door to supply a portion of hot wash water or rinse water supplied to the lower nozzle arms to the upper nozzle arm. When the upper opening of the washing tub is opened, the door and upper nozzle arm are housed in a rear portion of said washing tub.

Dishwashing machine

A dishwashing machine having a washing chamber, a wash tank provided at a bottom of the washing chamber to store an amount of hot wash water therein, a wash pump mounted to a bottom portion of the tank to pump up the wash water therefrom, a pair of wash arms supplied with the wash water by the wash pump, a rinse pump arranged to pump up fresh hot water supplied thereto from a source of hot water, and a pair of rinse arms supplied with the fresh hot water by the rinse pump, a drain box arranged within an upper portion of the tank and associated with a side wall of the tank to form an opening in communication with the bottom portion of the tank, a drain pipe connected to a bottom wall of the drain box and being extended outwardly through the bottom wall of the tank to drain the wash water received by the drain box, an overflow pipe secured to the bottom wall of the drain box to permit the upward flow of wash water from the bottom of the tank, and a tiltable plate arranged above the drain box to introduce the wash water flowing down from the washing chamber into the drain box when placed in a first position in prewashing operation and to introduce the wash water or fresh hot water into the bottom portion of the tank when placed in a second position in washing and rinsing operation.

In a dishwashing machine having a washing chamber, an electrically operated wash pump for pumping out wash water from a wash tank in the washing chamber, an electrically operated rinse pump for pumping out heated water from a gas booster heater, and wash and rinse arms arranged within the washing chamber to be supplied with the wash and heated water from the wash and rinse pumps for directing jet streams of the wash and heated water to tableware racked in the washing chamber respectively, an electric control apparatus is arranged to mix cold water from a source of cold water into the heated water to form mixing water and to control the rinse pump such that the rinse arm directs jet stream of the mixing water to the racked tableware. The electric control apparatus is further arranged to control the wash pump in response to finish in control of the rinse pump such that the wash arm directs jet stream of the wash water to the racked tableware and to again control the rinse pump in response to finish in control of the wash pump such that the rinse arm directs jet stream of the heated water to the racked tableware.
