Abstract

DC60 (24/02/41) Automatic Ice Maker for Refrigerator There will be a portion of the ice tray that were placed in a low temperature atmosphere for repeated ice making cycles. including for receiving water that was supplied and kept there to freeze the water. separate the ice from that section The water tank was installed by detachable so that it was positioned above the ice tray and which had a water outlet built into the bottom of the section. and the water supply valve where The water outlet is normally kept in a closed state. Tank detector for detecting the installed water tank. valve control device which has a rod that can be moved vertically and curled solenoid electromagnet wire which when stimulated with energy will raise the level of the stem to Keep the water supply valve open. The valve control device controls the opening time of the water supply valve so that the amount of water flowing from the water tank outlet is controlled via For supplying water for piloting water that flows from the water outlet of the water tank. into the input tray ice and controller It is the control range of the solenoid solenoid of the device. control the valve operation to make the solenoid solenoid energized Normal excitation is for a pre-set period of time and so is the solenoid. The solenoid is energized for a shorter time than the preset time when it is present. Initial water supply to the ice tray which occurs after detecting the setting of the water tank Automatic ice maker for refrigerator There will be an ice tray that is placed in a low temperature atmosphere for repeated ice making cycles. including for receiving the water supplied and storing it for freeze water. The ice is separated from that section and it is re-supplyed with water. The water tank, which is removable, is positioned above the ice tray. and which has a water outlet built into the lower part of that section. and a water supply valve, which normally maintains the outlet in a closed state, a tank detector for detecting a water tank in which the valve actuator is set. which has a vertically sliding rod and a solenoid solenoid. which when stimulated with energy will raise the lever of the water supply valve to open. The valve actuator controls the opening time of the water supply valve. So that the amount of water flowing from the water tank outlet is controlled, the way for the pilot water to flow from the water tank outlet. into the ice tray and controls. It is the solenoid solenoid control range of the valve control device to make the solenoid solenoid is supplied with normal excitation energy for a preset period of time and to the solenoid solenoid The activation energy is provided for a time shorter than the preset time when initial water is supplied to the ice tray. which occurs after detecting the setting of the water tank

Claims (6)

1.Automatic ice maker for refrigerator Containing Ice tray The water tank is detachable so it is positioned over the ice tray. And which has an outlet created in the lower part of that section And the water supply valve Which normally maintains the outlet in the closed state Valve actuation devices including vertically sliding stem and solenoid coil Which, when energized, the lever is raised so that the water supply valve is opened. The valve actuation device controls the opening time of the supply valve so that the amount of water coming out of the water tank outlet is controlled and the way for supplying water. That guides the water flowing out from the water outlet of the water tank. Into the ice tray It is characterized by the fact that the solenoid coil is energized normally for a predetermined time period. It was energized for a shorter, predetermined time when the water was initially supplied to the ice tray. Which occurs after detecting the setting of the water tank 2. Automatic ice machine According to claim 1, where the initial water supply will be performed. After the water tank was emptied and later filled with water. 3.Automatic ice machine According to claim 1 or 2, where the valve actuators, including the pusher, are worn in the cylindrical pilot mechanism. In order to be shifted vertically When stimulating energy is given And cut off the power of the solenoid solenoid Which is for this reason will move the shaft vertically And the cylindrical pilot and the push-in machine have the inner edge of the curved top end and the outer edge of the curved bottom end respectively. 4.Automatic ice machine According to claim 3, where the cylindrical pilot and the pusher are surface treated to reduce sliding resistance. 5.Automatic ice machine According to claim 3 or 4, in which the water supply channel has a bottom formed with a through hole at one Which the rod will pass through and the control device The action of the valve is placed under the passage for the water supply. And includes a second through hole holster that was made Through the top wall Of that part so that the stalks go By penetrating that part And the annular overhang was built on the upper face of the upper wall to surround the second through hole. The compacted part is worn in the first through hole and the sealing plate is worn with the annular protrusion to compress the compact. 6.Automatic ice machine According to claim 5, the casing of the valve control device There is an inlet that is built into the inner face of the upper wall of that section to align with the annular overhang.
