Water supply device for automatic ice maker

Abstract

A water supplying device for automatic ice making machine is provided with a feed water tank 14, a feed water pump 16, a motor 20 and a feed water route 18 guided to the outside of the tank out of the feed water pump while the feed water pump 16 is attached to the lower surface of a lid 24 so as to abut against an inside wall surface of the feed water tank 14 and the motor 20 is arranged in a motor receiving section 39 at rear side of the feed water tank 14 to pump up water in the feed water tank by transmitting the rotation of the same to the feed water pump 16 through a magnetic force. In such a water supplying device, a recess 60 and a projection 62, which are fitted with each other, are provided at the abutting part of the feed water pump 16 and the feed water tank 14 while another recess 64 and another projection 66, which are fitted with each other, are provided at the abutting part of a motor receiving section 39 and the feed water tank 14 while these are fitted to align the central axis of the feed water pump 16 with that of the motor 20.The device provided by this invention prevents the generation of abnormal sound by improving the positional accuracy of a feed water pump in a tank and a motor out of the tank.

Description

technical field [0001] The invention relates to a water supply device for an automatic ice maker of a refrigerator. Background technique [0002] The automatic ice maker of the refrigerator supplies a certain amount of water to the ice-making tray placed in the freezer (ice-making room), makes ice in the ice-making tray, and reverses the ice-making tray after the ice-making is completed, so that the ice in it The ice is automatically made by falling into the ice storage container provided below, and this automatic ice maker is provided with a water supply device for supplying water to the ice making tray. [0003] Such water supply equipment as Figure 6 As shown, there is a detachable water tank 14, a magnetically coupled water pump 16 and a motor 20 arranged on the water tank loading portion 12 in the refrigerating room 6, and a water supply path 18 connected to the water pump 16 and drawn out to the outside of the water tank 14. The water in the water tank 14 is sucked o...

Problems solved by technology

[0005] However, when the water pump 16 is installed on the detachable water tank cover 24 in this way, a positional deviation sometimes occurs between the water pump 16 and the water tank wall surface.

Especially when adopting the detachable structure of water pump 16, pipeline 14 and cover 24 for the convenience of cleaning, because of the water tank body 22 and the water tank cover 24, the water tank cover 24 and the pipeline 40, the pipeline 40 and the water tank 16, there are relatively Multiple connection parts, so it is easy to reduce the positional accuracy between the water pump 16 and the water tank wall

[0006] Once a positional deviation occurs between the water pump 16 and the water tank wall, even if the water tank 14 is correctly positioned on the water tank mounting part 12, a positional deviation will occur between the water pump 16 and the motor 20, and abnormal noise will occur due to misalignment.
