Abstract: Provided is a through-type water tank for an ice maker, including: a body; a water tank, a basket, an evaporator, and a refrigeration system arranged within the body, where a slide rail is arranged within the body, the water tank is mounted on the slide rail and is slidable outward from the front side of the body; a communication pipe and a liner are arranged at a rear side of the water tank, wherein the water tank is in fluid communication with the liner via the communication pipe; a piston is disposed at a connection between the water tank and the communication pipe, where the piston expands when the water tank is pulled outward, and when the water tank is pushed inward, the communication pipe is inserted into the piston, compressing the piston and establishing fluid communication with the water tank.

Abstract: An evaporator structure, an ice maker, and a method for heat exchange are provided. The evaporator structure includes: a freezing valve, configured to independently control a refrigerant flow rate of a refrigerant in each of at least two capillary tubes; the at least two capillary tubes, disposed between the freezing value and an evaporator, and configured to transmit the refrigerant into the evaporator; and the evaporator, configured to vaporize the refrigerant for heat exchange.

Abstract: The present invention provides a stable fat-soluble active ingredient composition, microcapsule and process for preparation and use thereof. The fat-soluble active ingredient composition comprises tocopherol, vitamin C palmitate and a fat-soluble active ingredient; wherein the weight ratio of tocopherol to vitamin C palmitate is 2-8:1, the weight ratio of a combination of tocopherol with vitamin C palmitate to the fat-soluble active ingredient is 7-13:100. The present invention obtains a novel antioxidant composition without hidden dangers for improving the stability of the fat-soluble active ingredient by screening a combination of antioxidants and adjusting their proportion and dose.
