[Detailed description of the invention]

(a) 1ψ Industrial field of application The present invention relates to an ice maker, and the present invention relates to an ice making machine. (b) This relates to a water spout cleaning method for a 11v ice maker.
PRIOR ART In general, in this type of ice making machine, when ice is formed in the ice making compartment, the water tray tilts to open the ice making compartment, and the ice removed from the ice making compartment during the dehydration operation slides on the surface of the slanted paddy field 1. It is configured to fall into the ice storage room. Therefore, at the end of ice making, the lower surface of the ice that has frozen in the ice making chamber is in close contact with the surface of the water tray, and even after the water tray has moved fj1, a thin layer of ice adheres to the water fill 1M surface and blocks the water fountain hole. ',,jj points were there. Therefore, it was safe to spray water on the surface of the water tray to wash away the thin layer of ice that had settled on the surface of the water tray before starting the next ice making process. The conventional water surface cleaning method has been a simple method of sprinkling water (iW 71j: constant j, 1-if, regardless of 71j) on the surface of the water pan for 1 time. j
If j is low and the watering f)rA degree is low, the watering time is insufficient and the thin ice layer cannot be completely washed away.On the other hand, if the surrounding ttJA degree is high and the watering iM moon is still low, it is relatively quick. Against the thin ice layer γ) 1r. There was a surplus of 11 days left over for watering, and the watering during that time was completely wasted. (c) Object of the Invention The present invention provides a method for washing a water dish, which performs appropriate water sprinkling depending on the level of the water sprinkling temperature in order to reliably wash away the thin ice layer adhering to the water dish and prevent unnecessary water sprinkling. 2) Structure of the Invention The present invention is a so-called inverted cell type ice maker, in which the water supply valve is opened regardless of the temperature of the water supply for at least a first predetermined period from the end of ice production to the start of the next ice production. water to the water tray, and during a second predetermined period that is continuous before or after the first predetermined period, when the water sprinkling temperature is higher than the predetermined temperature, the water supply valve is closed to stop the water sprinkling to the water tray.
