External water tank and ice maker

Abstract

The invention discloses an external water tank and an ice maker. The external water tank is of an inverted cone structure. The ice maker comprises an ice maker body and the external water tank arranged outside the ice maker body. The external water tank communicates with an internal water tank located in the ice maker body. A flow controller is arranged in a communicating channel between the external water tank and the internal water tank. The external water tank is used for supplement so that the size of the internal water tank can be designed to be smaller; on the one hand, the external water tank can supply water into the internal water tank continuously according to requirements, and thus the defect of frequently adding water into the internal water tank can be overcome; and on the other hand, the volume of the internal water tank is reduced, the amount of water contained in the internal water tank is reduced accordingly, the amount of water, needing to be pre-cooled before ice making, in the internal water tank is reduced, the pre-cooling time is shortened, and thus the effect of improving the ice making efficiency can be achieved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to ice cube manufacturing equipment. Background technique [0002] The working principle of the ice machine is: the chilled water in the water storage tank is continuously circulated through the plate or compartment evaporator (wherein, before freezing, the water in the water storage tank is circulated through the evaporator for cooling, when the water is It will slowly freeze on the surface of the evaporator when it is cooled to 0°C); after the compressor is running, it will be sucked—compressed—exhausted—condensed (liquefied)—throttling—and then in the evaporator with - The low-temperature evaporation from 10°C to -18°C absorbs heat and vaporizes, and the frozen water continuously condenses into an ice layer on the surface of the lower-temperature evaporator at a water temperature of 0°C. When the ice layer condenses to a certain thickness, after the evaporation temperature...

AI Technical Summary

Problems solved by technology

[0005] First: Since the water storage tank is placed inside the ice machine, due to the influence of the size of the ice machine itself, the capacity of the water tank should not be too large. In the process of ice making, with the increase of ice output, the required The water also increases, which requires frequent addition of water during the ice making process

[0006] Second: Because the water needs to be pre-cooled before cooling, pre-cooling is also to pre-cool the water in the water tank. There is a separate water tank in the machine. If the amount of ice cubes to be made is not very large, the whole box of water needs to be pre-cooled when pre-cooling , too much water is stored, but only part of the water is used in the end, and the unused water is pre-cooled in vain, which leads to long cooling time and low efficiency

[0007] Third: It is inconvenient to add water, you need to use an additional container to hold water and pour it into the water storage tank

[0008] Fourth: not easy to clean
