Ice making machine

Abstract

The invention discloses an ice making machine. The ice making machine comprises an accommodating tank for accommodating water, and a cold air refrigerating module for providing cold to the accommodating tank for changing the water to ice, and also comprises an air guide cover arranged at the periphery of the accommodating tank; a heat exchange air duct for enabling cold air to pass through is sandwiched between the air guide cover and the outer wall of the accommodating tank; and when the ice making machine makes the ice, the cold air passing through the heat exchange air duct transfers the cold from the outer wall of the accommodating tank into the accommodating tank for cooling the water. The accommodating tank directly exchanges heat with the cold air in the heat exchange air duct through the outer wall, so that the heat exchange area between the water in the accommodating tank and the cold air can be effectively increased, and the ice making efficiency is improved; and as the cold air does not make direct contact with liquid-state water or solid-state ice in the accommodating tank, the made ice has no peculiar smell, and is clean and sanitary.

Description

technical field [0001] The invention relates to the refrigeration field of refrigerators, in particular to an ice maker used in refrigerators. Background technique [0002] Refrigerators have become one of the routine home appliances in daily life. In addition to fresh-keeping and freezing functions, using refrigerators to make ice is also an application that is becoming more and more popular. The ice-making process of existing air-cooled refrigerators is mainly through cold wind blowing into the The inside of the storage tank directly exchanges heat with water to realize ice making. The cold air used is the circulating air of the entire refrigeration system. However, the above method of ice making has the following problems: After multiple cycles of the cold air through the system, it is easy to carry food odors , and even carry a certain amount of bacteria, so that the ice cubes produced in this way have peculiar smell, which will affect the taste and even be unsafe to eat...

[0002] Refrigerators have become one of the routine home appliances in daily life. In addition to fresh-keeping and freezing functions, using refrigerators to make ice is also an application that is becoming more and more popular. The ice-making process of existing air-cooled refrigerators is mainly through cold wind blowing into the The inside of the storage tank directly exchanges heat with water to realize ice making. The cold air used is the circulating air of the entire refrigeration system. However, the above method of ice making has the following problems: After multiple cycles of the cold air through the system, it is easy to carry food odors , and even carry a certain amount of bacteria, so that the ice cubes produced in this way have peculiar smell, which will affect the taste and even be unsafe to eat; even if the filter is used in the cold air duct, the above situation cannot be completely avoided; in addition, because the cold air can only touch the storage tank On the upper surface of the internal water, the heat exchange area between cold wind and water is limited, which affects the ice making efficiency
