Specific embodiment
Described in this specification " on ", D score direction with the upper and lower in accompanying drawing 1 to corresponding.Arrow in accompanying drawing 1
Point to identical with water (flow) direction.
Referring to shown in accompanying drawing 1, the ice machine in the present embodiment includes:Refrigeration system, the refrigeration system includes compressor, steams
Hair device 1, condenser, expansion valve, wherein, evaporator 1 is connected with refrigerant pipe 5, and the lower surface of evaporator 1 is provided with multiple downward
The ice mould 2 of extension, ice mould 2 is made up of the good metal material of heat conduction(Usually copper, stainless steel, aluminium etc.);
Water box 4, for holding water purification, positioned at the underface of evaporator 1, to make ice mould 2 easily immerse in water purification, described water box
4 is in the trapezoidal shape of oral area narrow base wide, and when ice making works, the major part of ice mould 2 is immersed in below the water surface, after finishing ice-making,
Water box 4 are rotated, and water and ice are poured out;
Water circulation mechanism, for the water for circulating is provided in water box 4, water circulation mechanism to be included to the described water filling of water box 4
Water injection pipe 61, water pump 6 and described water box 4 inner space water pump oral siphon 62, the water filling port of water injection pipe 61 is located at water
The inclined-plane top of the halfpace of box 4.Described water pump 6 is located at the side of water box 4, and described evaporator 1 is located at just going up for water box 4
Side.
The cross section of described ice mould 2 is circle, rectangle, trapezoidal or parallelogram, and the shape according to ice mould can be made
Obtain the ice cube of respective shapes.Be obtain with specific pattern ice cube, in the present embodiment, be provided with the bottom face of ice mould 2 to
The drafting department of outer lug, correspondingly ice mould surface be not provided with the part of pattern and be referred to as non-drafting department, the table of drafting department protrusion ice mould 2
The height in face about 1.5~4mm, obtained ice cube center is correspondingly formed a pattern for depression, and the pattern can be word or flower
Line or figure etc., in other embodiments of the invention, the drafting department can also be opened on the periphery of ice mould, be can also be
It is formed in the depression on ice mould periphery.
Be rationally control water box in space, manufacture ice cube as much as possible, it is to avoid adhesion between ice cube, multiple described in
Ice mould 2 is staggered in the lower surface of described evaporator 1.The thermal conductivity of ice mould 2 is good, can select solid metallic materials system
Into, it is also possible to be to improve refrigerating efficiency as the present embodiment, ice mould 2 be designed to hollow structure, and the inner chamber of ice mould 2 with
Evaporator 1 is connected, and the inner chamber for enabling the refrigerant to enter into ice mould 2 is circulated, and improves cooling velocity, when accelerating ice making
Between.
When refrigeration system is freezed, water forms ice cube on ice mould 2, and when refrigeration system is reversely heated, ice cube departs from ice mould
2.In general the drafting department and non-drafting department on the ice mould 2 are deiced simultaneously, and it is complicated to some patterns, require definition it is high,
The relatively thin ice cube of patterned layer, in order to obtain definition high, the complete ice cube of pattern in detail and edge, can be by designing ice mould 2
Thickness and drafting department area coverage deice order to change, and non-drafting department is first deiced, and are deiced after drafting department, on ice mould 2 everywhere
Wall thickness be slightly different, the wall thickness of drafting department is slightly larger than the wall thickness without area of the pattern, and the outer surface of described ice mould 2 is described
Drafting department overlay area area less than non-drafting department overlay area area, this causes that the water of non-drafting department first freezes, figure
Frozen after the water in case portion, when refrigeration system is reversely heated, non-drafting department is first deiced, and drafting department is deiced again, will not be led when deicing
Pattern partial melting is caused to obscure.Because ice cube is little in itself, the time order and function difference that drafting department and non-drafting department are deiced when deicing
It is small, do not interfere with the time of deicing.
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 no longer connects with evaporator, and each ice mould 2 is detachably connected to institute
On the lower surface of the evaporator 1 stated, so when user needs conversion ice cube pattern, can be by changing with different pattern
Ice mould 2 is realized.Specifically, multiple projections are wholely set on the lower surface of evaporator 1, ice mould 2 is set in by interference fit
Projection outside, or ice mould 2 is threadedly coupled with projection, realizes fast quick-detach;Another way is to set described multiple ice moulds 2
Put on an installing plate, then by the installing plate integral installation on an evaporator, and ensure that installing plate is led with the good of evaporator
Heat.
Ice machine operation principle is:Refrigerant enters in evaporator 1 through refrigerant pipe 5, makes patterned on evaporator 1
Ice mould 2 is cooled down, and the bottom of ice mould 2 is immersed in below the water surface, and water is frozen into ice cube 3 on ice mould 2, and the water in water box 4 is in system
Constantly twitched by water pump 6 during ice, the water in water box 4 is ceaselessly flowed, therefore the transparent bubble-free of obtained ice cube 3, ice
Pattern contour on block 3 is clear.After the completion of ice making, reversely heated by refrigeration system, make ice cube depart from ice mould, now water box to
Lower rotation, drops out ice cube, after water and ice separation, by ice cube feeding ice bank.
