[Invention and Technical Field]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice making machine. [Prior Art] Thin ice is widely used in the industry when transporting catches to consumers. The crushed ice is a common technique of crushed ice. However, the existing shortcomings are: the food industry, especially the marine food industry temple ’uses ice crushers to refrigerate and freshen the ice catcher, and it is only one of the following technologies:

As it is known > Yongquan-type thin crushed ice and Yongban separators are "containers ..." broken: giant liquid separators are used to separate evapotranspiration and tritium. It flows to the compressor. In addition, the It is known that there is no liquid inner wall and an outer wall to form a pressure vessel. 7 ^ Each element, the inner wall and the outer wall are made of ultra-thick metal: a pressure-resistant container (large-volume cylinder) and thick The demand for metal is < far greater than the high pressure of the refrigerant at normal temperature (when the compressor is not running, $ is used = working temperature of minus 25 degrees Celsius, it will make the thickness not% and almost

And shrinkage (thermal expansion and cold shrinkage) so that the container changed drastically. The rabbits expanded and resisted pressure and had to be made of metal. ‘Yes] = wall The conduction effect is greatly reduced. It is considered to be used to make 1 'thickness, so it must be selected from materials with good thermal conductivity, such as aluminum or copper. However, the material of = f, and its strength is not enough to withstand the high pressure mentioned above. The materials such as Min are too soft, and carbon steel is generally used.

Page 5 422569 Description of the invention (2) Superseded. However, the problem that carbon steel is easy to rust will affect the environment and rust will not be used for a long time. Rusty materials to replace carbon steel, such as stainless steel, which has poorer conductivity than carbon steel, and greatly reduces the use of steel for conventional technologies. The pressure vessel has a more serious problem due to the poor freezing effect. In order to avoid rusting of carbon steel, it is well known that the inner surface of Yongquan-type thin ice crusher ice machine is coated with a thin layer of chromium. However, due to the cost and waste of the production equipment, the force of crushing ice is required to impact the frozen surface, and it will fall off and cannot be stored for a long time. The frozen watch is exposed, and the carbon steel will still rust. If the conventional technology is used to make seawater non-steel material as the inner cylinder wall of the evapotranspiration machine, the stainless steel material can completely resist rust. Compressors with such effects, to compensate for the above-mentioned because of good stainless steel, but also because of this, the production has been increased so that when the liquid level is not in the proper agent leakage due to poor control, the liquid level is not in the proper known Yongquan style Evapotranspiration occasionally returns to v-pressure issues. The liquid hammer effect, in the conventional technology, is so powerful as to be one. However, it needs long-lasting durability for freezing, and it is more durable and can resist the thermal effect of stainless steel. If the degree of rust is greater, it will make the front ice crusher and the carbon steel on the surface, which only increases the equipment.制 间。 System room. What's more, when a thin layer of chrome is plated, which causes the carbon steel inside to become thin crushed ice, the equipment uses' because only the southern grade is used, the freezing caused by strong steel must be used. The effect is not as good as 0 when the horizontal plane, or because of the cold; at the east horizontal plane, 'some oil will shrink the machine, so it also causes some thin inner walls with expansion guides in and out of the bottom.

Page 6 200422569 Description of the invention (3) The thin ice crushing ice maker uses hydraulic pressure to ensure that when the system is operated again, the system will turn off the lights. However, the :: time duration: yes = loose machine. Causes the machine to stop abruptly and cannot be noticed. = The residual cold repellent will occur due to gravity. 'Yes = 2 Suddenly stop the machine' and then immediately resume operation with the cold repellent. Above this temperature, the expansion of the shore return capacity II: b will cause the refrigerant to return to the compressor 'and immediately cause serious damage to the valve. m | xe The centrifugal force experienced by the frozen mixture in the coil of the extended-oriented evapotranspiration will cause the frozen mixture to contact the inner wall of the coil more frequently 4 to the outer wall of the expanded coil 3, such rotation will cause very little heat exchange. And the surface of the inner wall of the cylinder (the frozen surface that forms the ice) is also less evaporated, so the productivity is reduced, and the efficiency of ice formation is not good. ^ As the above problems already exist in the conventional expansion-oriented thin crushed ice maker ', it cannot perform satisfactorily, especially the problem of sudden shutdown and immediate restart, and the inefficiency, inability to operate for a long time, It meets environmental sanitation and the cost is not low. The present invention therefore attempts to remove or reduce the aforementioned disadvantages, and some solutions are summarized as follows: The present invention is characterized by an extended guidance system for the input of refrigerant at the bottom (the evapotranspiration can be achieved in the coil of an evapotranspiration system, such as a semi-spring spring evapotranspiration system. Effect) And the gas in the top outlet is completely evaporated. Therefore, there is no problem of the liquid hammer effect to damage the valve and the piston. This type of machine can overcome the problems caused by sudden shutdown.

Page 7 200422569 V. Description of the Invention (4). ^ Invention can use stainless steel cylinders as cold; east surface 夂 A, the prior art has some choices to meet the freezing effect. And can be strange, such as preventing the aforementioned conventional problems, such as rust, poor environmental sanitation, and high costs. In fact, the stainless steel Jifuxia steel is poor, but the square channel ϋ 固定 fixed to the expansion guide coil can overcome the problem of poor heat conduction. The buffer board is auxiliary training and moves toward the square channel to achieve more evapotranspiration effects. . ^ The buffer plate according to the technical features of the present invention is used in the predetermined component of the directional evapotranspiration coil, and during the process of evapotranspiration of the inner cylinder 11 of the refrigerant, it is guided to the inside of the evapotransmitter = heat recovery. In the reflux freezing of the inner wall of the evapotranspiration machine 14, the surface cold beam efficiency is promoted to achieve the purpose of making ice. Changing the direction of the liquid flow also helps to promote the evapotranspiration bubbles of the refrigerant formed on the inner wall of the evapotranspiration machine, which improves the heat exchange efficiency and speeds up the evapotranspiration. In the machine of the present invention, it is also possible to use a thin layer of chromium plating on the surface instead of using (such as the extended guided ice crusher in the conventional way) 7 ^ surface fixed a plurality of buffer plates to improve the efficiency of cold. The present invention is not a principle of a pressure vessel in a prior art machine, so the thinner carbon steel of the inner cylinder wall of the present invention replaces the conventional Yongquan type thin ice crushing ice maker to resist thick walls. The thin wall of the present invention has better heat exchange rate, such as 2 better evapotranspiration and ice-making effects. In addition, the volume is smaller and lighter, and the V cost of ice making equipment is saved. The aforementioned solution of the present invention can reduce the huge volume and equipment cost, and at the same time, it is more hygienic and has a longer equipment life. Good at the same time to help such a change in carbon steel in this table can be provided under pressure to provide quality and savings and improve 200422569 V.

In order to further improve the cooling efficiency, the refrigerant is extended to guide the evapotranspiration coil through the square channel. It is provided with a plurality of buffer plates 53 inside. The buffer plate is used to guide the direction of the water flow of the refrigerant to the inner wall of the extended guide coil. . The inner wall of the evapotranspiration coil 3 is also the inner wall of the cylinder. This inner wall also serves as a freezing surface to make thin crushed ice. The advantages and spirit of the present invention can be further understood by the following drawings of the invention. [Embodiment] Please refer to FIG. 1 and FIG. 2, which are only seen from the side of the thin ice crusher according to the first embodiment of the present invention and the top cross section. In a word, the thin ice crushing ice maker includes a cylindrical evapotranspiration machine i, a water distribution device 2, and an extended long ice crushing device 4. The cylindrical evapotranspiration machine 1 has an internal cylinder 丨 丨 and a cylinder 12, the two cylinders are concentric, and a circular inner wall 14 is formed therebetween. The cymbal wall is used as:状 为 冰 制 室 15。 As the ice making chamber 15. Furthermore, we will use = after the fan machine 1 ′, and use some conventional heat-insulating materials 16 to separate the t :: ° = thane). In accordance with the conventional thin ice crusher ice maker, the thin ice crusher of the present invention has an evapotranspiration machine 1, and is equipped with a 20042004569. V. Description of the invention (7) Several evapotranspiration coils 3 fixed to the extension guide The buffer plate in the square channel, and the evapotranspiration coil 3 is concentrically installed in the condensation chamber 3. In the top section of the ice-making chamber 15, a water flow distribution device 2 is installed here.泫 The water flow distribution device 2 includes a main shaft 2 1, a circular water tray 2 2, and a plurality of tubes 2 3 of a uniform and uniform angle scoop. The water flow is frozen and guided uniformly, and the refrigerant in the inner cover 14 and the outer cover sheet of the evapotranspiration machine 1 rises, while the continuous flow flows downward. This achieves better heat exchange, resulting in better freezing results. The extended long ice crushing device 4 includes a rotating shaft 41 installed in the center of the ice making chamber 15 of the evapotranspiration machine 1, a holding arm 42, and an ice cutter 43 made of hard stainless steel.

Fig. 2 shows a plurality of buffer plates in a square channel of the extended evapotranspiration coil. There is an obvious defect in the thin ice crushing ice machine of the conventional technology, that is, the cooling effect provided by the scatter machine is poor. The evapotranspiration machine in the previous case technology includes an inner cylinder and an outer cylinder to form a jujube chamber, an insertion device and a guide outlet, which are used to introduce and export refrigerant, so that The shape of the huge spring-spring evapotranspiration chamber can be used to resist the situation that the refrigerant evapotranspiration effect is poor due to heat exchange. Furthermore, due to centrifugal force, the refrigerant will also have more contact opportunities with the outer wall of the extended evapotranspiration than the inner wall, and the cooling effect is also poor.

Page 11 200422569 V. Description of the invention (8) " "-^-In the present invention, an extension-oriented best embodiment is presented. In order to improve the evapotranspiration flow in the present invention, the evapotranspiration machine 6 is provided with an expansion coil 3, an insertion device 51 at the bottom, and an outlet 5 2 at the top π of the ice making chamber. The extended evapotranspiration coil 5 is connected to the cylindrical evapotranspiration machine 1 and arranged concentrically, and forms a square channel. To further improve the cooling effect ', a plurality of buffer plates 53 are provided in the extension coil 3. The plurality of punch plates 53 are equally spaced and distributed on the center element, and are arranged obliquely at a predetermined angle to direct the liquid flow of the refrigerant to the inner wall 6 4 of the refrigerating surface evapotranspiration machine 6. In the present invention, in theory, the extended evapotranspiration coil 'having a square cross section is easier to provide the buffer plate. The inner cylindrical wall 3 and the buffer plate 5 3 are made of stainless steel to resist rust, to maintain environmental hygiene and to make the equipment durable. Referring back to FIGS. 1 and 2, the refrigerant enters from the bottom through the insertion device 51 and flows upward to the guide outlet 52 at the top. When the refrigerant flows upward 'and is guided to the inner wall 14 of the evapotranspiration machine 1 by the buffer plate 5 3. This will bring two effects. First, the evapotranspiration effect of an expansion-oriented half-spring is completed. In addition, it also has a better heat exchange effect and simpler operation. And through the control of the temperature adjustment expansion valve, the completely evaporated refrigerant leaves the outlet 5 2 from the top, so as to eliminate the liquid hammer effect caused by the sudden stop of the machine, which will cause damage to the valve and piston of the compressor. Possibly. Second, when the refrigerant is directed to Yongbi 64, better contact and evapotranspiration are completed at this time, and it has a better cooling effect, that is, more ice 7 can be made. If the refrigerant is replaced in a top-down manner,
