Embodiment Construction
[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0025] The invention discloses a method for improving the refrigeration efficiency of a water dispenser: drinking water enters the cold tank 1 to be refrigerated; ) of the drinking water to be refrigerated continues to flow, and the flow velocity is higher than the minimum flow velocity that can freeze the drinking water to be refrigerated, so as to avoid freezing near the heat exchanger 2.
[0026] In the process of cooling water, the water in the cold tank 1 is forced to flow, which solves the problem of easy freezing in the cold tank 1 close to the heat exchanger 2; cold water at a lower temperature can be produced without worrying about freezing; The refrigeration efficiency of the entire refrigeration system of the water dispenser ensures sufficient cold water.
[0027] Wherein, the flow direc...

The invention discloses a method for improving refrigerating efficiency of a water dispenser and the water dispenser, and belongs to the technical field of a water dispenser and a control method thereof. The method for improving the refrigerating efficiency of the water dispenser and the water dispenser are designed to solve the problem that the effect of freezing suppression of an existing cold tank is poor. According to the method for improving the refrigerating efficiency of the water dispenser, drinking water enters the cold tank to be refrigerated; the to-be-refrigerated drinking water inthe cold tank continuously flows at least within the set time before reaching the water outlet temperature, and the flowing speed is higher than the lowest water flow speed capable of freezing the to-be-refrigerated drinking water. By means of the method for improving the refrigerating efficiency of the water dispenser and the water dispenser, the problem that the periphery of a heat exchanger isfrozen is solved, the periphery of the inner wall of the cold tank continuously keeps the high degree of supercooling, and the heat exchange efficiency of the heat exchanger and water is further improved.
Description
technical field [0001] The present invention relates to the technical field of water dispensers and control methods thereof, in particular to a method for improving refrigeration efficiency of a water dispenser and a water dispenser for realizing the method for increasing refrigeration efficiency of a water dispenser. Background technique [0002] Water dispensers usually have the functions of heating hot water and cooling water, wherein cooling water is performed by a heat exchanger (evaporator). Specifically, the drinking water is heat-exchanged with the heat exchanger in the cold tank to produce cold water. The temperature of the cold water produced is usually between 6°C and 10°C. When the temperature of the cold water produced is lower, it is easy to freeze at the position close to the heat exchanger, reducing the cooling efficiency. [0003] In order to solve this problem, there is a return pipe installed on the outlet pipe of a water dispenser, and part of the outlet...
