The invention has the advantages that the present invention can produce it is in the same size, internal with figuratum ice cube, due to making ice
Cheng Caiyong flowing water circulating cooling, manufactured ice cube are transparent, the clear patterns on ice cube, can be by decorative pattern, text, figure etc.
It is formed on ice cube, obtains the ice cube of special visual effect.
Specific embodiment
"upper" described in this specification, "lower" direction are corresponding with the upper and lower direction in attached drawing 1.Arrow in attached drawing 1
It is directed toward identical as water (flow) direction.
Referring to figure 1, the ice machine in the present embodiment includes: refrigeration system, which includes compressor, steams
Send out device 1, condenser, expansion valve, wherein evaporator 1 is connected with refrigerant pipe 5, and the lower surface of evaporator 1 is equipped with multiple downward
(usually copper, stainless steel, aluminium etc.) is made by thermally conductive good metal material in the ice mould 2 of extension, ice mould 2;
Water box 4, it is described to make ice mould 2 be easy to immerse in water purification positioned at the underface of evaporator 1 for holding water purification
Water box 4 are in the trapezoidal shape of the wide narrow base of oral area, and when making ice work, the major part of ice mould 2 is immersed in the water surface hereinafter, finishing ice-making
Afterwards, water box 4 rotate, and water and ice are poured out;
Water circulation mechanism, for providing the water circulated into water box 4, water circulation mechanism includes to the water box 4
The water injection pipe 61 of water filling, water pump 6, the water pump water inlet pipe 62 being connected to the inner cavity of the water box 4, the water filling port position of water injection pipe 61
Above the inclined-plane of the halfpace of water box 4.The water pump 6 is located at the side of water box 4, and the evaporator 1 is being located at water box 4 just
Top.
The cross section of the ice mould 2 is circle, rectangle, trapezoidal or parallelogram, can be made according to the shape of ice mould
Obtain the ice cube of respective shapes.To obtain the ice cube for having specific pattern, in the present embodiment, be equipped on the bottom face of ice mould 2 to
The drafting department of outer lug, correspondingly the part of the not set pattern of ice mould surface is referred to as non-drafting department, which protrudes 2 table of ice mould
The height in face about 1.5~4mm, ice cube center obtained are correspondingly formed the pattern of a recess, which can be text or flower
Line or figure etc., in other embodiments of the invention, the drafting department can also be provided on the periphery of ice mould, can also be
The recess being formed on ice mould periphery.
Rationally to control the space in water box, manufacture ice cube as much as possible avoids adhesion between ice cube, multiple described
Ice mould 2 is staggered in the lower surface of the evaporator 1.The thermal conductivity of ice mould 2 is good, and solid metallic materials system can be selected
At, ice mould 2 can also be designed to hollow structure as the present embodiment, to improve refrigerating efficiency, and the inner cavity of ice mould 2 with
Evaporator 1 is connected, and the inner cavity for enabling the refrigerant to enter ice mould 2 is recycled, and improves cooling velocity, when accelerating ice making
Between.
When refrigeration system refrigeration, water forms ice cube on ice mould 2, and when refrigeration system reversely heats, ice cube is detached from ice mould
2.In general drafting department and non-drafting department on the ice mould 2 deice simultaneously, and it is complicated to some patterns, require clarity it is high,
The relatively thin ice cube of pattern layer can pass through design ice mould 2 to obtain clarity height, the complete ice cube of pattern in detail and edge
Thickness and drafting department area coverage deice sequentially to change, and deice non-drafting department first, deice after drafting department, on ice mould 2 everywhere
Wall thickness be slightly different, slightly larger than the wall thickness of not area of the pattern, the outer surface of the ice mould 2 is described for the wall thickness of drafting department
Drafting department overlay area area be less than non-drafting department overlay area area, this makes the water of non-drafting department first freeze, figure
It freezes after the water in case portion, when refrigeration system reversely heats, non-drafting department is first deiced, and drafting department deices again, will not be led when deicing
Cause pattern partial melting fuzzy.Since ice cube itself is little, the time order and function that drafting department and non-drafting department deice when deicing is differed
It is small, it will not influence and deice the time.
In the present embodiment, ice mould 2 is fixedly connected on evaporator 1 by welding method, non-exchange.Of the invention
In preferred embodiment, ice mould 2 is solid construction, and inside is no longer connected to evaporator, and each ice mould 2 is detachably connected to institute
It, can be by replacing with different pattern in this way when user needs to convert ice cube pattern on the lower surface for the evaporator 1 stated
Ice mould 2 is realized.Specifically, multiple pillars are wholely set on the lower surface of evaporator 1, ice mould 2 is set in by interference fit
On the outside of pillar or ice mould 2 is threadedly coupled with pillar, realizes fast quick-detach;Another way is to set multiple ice moulds 2
It sets on a mounting plate, then on an evaporator by the mounting plate integral installation, and guarantees that mounting plate and the good of evaporator are led
Heat.
Ice machine working principle is: refrigerant enters in evaporator 1 through refrigerant pipe 5, makes patterned on evaporator 1
Ice mould 2 is cooling, and the lower part of ice mould 2 is immersed in the water surface hereinafter, water is frozen into ice cube 3 on ice mould 2, and the water in water box 4 is being made
It is constantly twitched by water pump 6 during ice, flows the water in water box 4 ceaselessly, therefore the transparent bubble-free of ice cube obtained 3, ice
Pattern contour on block 3 is clear.After the completion of ice making, reversely heated by refrigeration system, make ice cube be detached from ice mould, at this time water box to
Lower rotation, drops out ice cube, and after water and ice separation, ice cube is sent into ice bank.
