Description of the invention (The present invention relates to an automatic ice maker, in particular to the structure of the drainage part of water overflowing from the ice-making water tank and water generated due to condensation. (Please read the precautions on the back before (Fill in this page) As such an automatic ice maker, for example, there is a closed-form ice making unit shown in Shikaihei 2_38〇63. On the lower side of an ice making chamber having an ice making compartment having a plurality of lower openings, it is possible to The components consisting of a water pan, a water tank, and a circulation pump are tilted back and forth to support the water pan close to the ice making compartment in the ice-making operation state, and the ice-making water in the water tank is sampled from a spray hole provided in the water pan with a circulation pump. Spray inside the ice making tray to let it freeze. After the icing is over, let the water tray leave the ice making tray and tilt it. After heating the ice making tray, let the formed ice cubes fall off, slide onto the water tray and drop into the ice storage. In this prior art, there is a problem that, because the outer shell of the water tank and the circulation pump is made of metal, especially in the water tank during ice-making operation, ice-cooled water cooled to close to 0 ° c is stored in the water tank. , Ice storage The water becomes water droplets, which dew on the surface of the water tank. After the water droplets increase and fall, the ice cubes stored in the ice storage tank are melted, or the ice cubes are stuck after re-freezing. In addition, when the water level is too high, When it is high, the excess ice-making water is directly discharged to the external overflow pipe. As a method to solve this problem, there is a technology shown in JP 9-210521. This is in an automatic ice maker with a closed-form ice making section. Under the water tank and the circulation pump, a drainage tank with a size that only the front end of the water tank projects is set up. The water droplets and water droplets falling from the water tank and the circulation pump casing after dew condensation and ice-making water overflowing from the water tank are collected from the water tank. The drainage port formed in the drainage bin is discharged to the outside. In addition, the two prior arts of the above-mentioned closed-form ice-making section 'are required to support a component composed of a water pan, a water tank, and a circulation pump capable of reciprocating tilting movement, Therefore, there are complicated structures, and the paper size is applicable to the Chinese national standard (〇 (S) A4 specification (21〇 < 297 mm) 4 »7348 A7 '' '------- B7 V. Description of the invention ( 2 ) '" The problem is prone to failure. As an automatic ice maker that solves the problems in the two prior arts mentioned above, the type of clothing ice ^ is structured as follows, and an opening ^ = is formed on the lower side of the front wall. The ice-making water phase of the ice #set body can be inserted from the horizontal direction in the horizontal direction. The ice-making water in the ice-making water tank is sucked in the circulating pump and transported to the water spray nozzle. The ice-making compartment of the ice-making department housing P-received ice-making chamber accepts the ice-making water to make ice, and after the ice is made, the ice cubes falling from the ice-making grate fall into the ice-making department casing. The ice slide in the middle of the body slides down and slides down to open the partition of the ice-making unit on the front side of the body due to its own weight and hanging down, and sends the ice out of the ice-making casing. This form of The ice-making section has a simple structure because the movable part only has a light partition that hangs naturally, so it is not easy to cause failure. In addition, the ice-making water tank is made of synthetic resin. Compared with metal products, the surface of the ice-making water tank has less dew condensation. There is no overflow hole like the second prior art. The overflow pipe connected to this discharges the excess ice-making water directly to the outside. In addition, such an automatic ice maker includes, for example, a run-down ice making unit shown in Japanese Patent Application Laid-Open No. 7-318207. This is to cool the ice-making board of the ice-making section, and use a circulating pump to supply the ice-making water in the ice-making water tank made of synthetic resin to the ice-making section and flow into the ice-making surface of the ice-making board to produce a plate-like shape. Ice, the part of the ice-making water flowing down that has not been frozen is returned to the ice-making water tank and supplied to the ice-making section again through the circulating pump. In the above 3rd and 4th prior art, although the ice-making water tank is made of synthetic grease, compared with metal products, the water in the ice storage on the surface and the paper size of the paper are applicable to the Chinese National Standard (CNS) Α4 specification (210X297 mm) (Please read the precautions on the back before filling in this page) Order |, Λ. 557348 A7 ^^ ~ E__ 5. Description of the invention (3) "-There is less dew, but the casing of the circulating pump It is made of metal with dew condensation on its surface, and it may drop after being enlarged. In this way, there are problems such as soiling the lower machine room and adversely affecting the machines inside it, and there is also the problem of melting the ice cubes or plates stored in the ice storage after falling into the ice storage, or The problem of ice sticking to ice cubes or plates. In addition, there are also problems that when the oil leaked from the circulation pump causes the oil in the lower part of the machine to become dirty, which may adversely affect the equipment inside it, there is also a problem that it falls into the ice storage and is stored in it. The problem of internal ice or plate pollution. Furthermore, an overflow pipe is connected to the ice-making water tank. When the ice-making water tank is removed and installed for cleaning, the overflow pipe needs to be removed, which is also a very troublesome problem. An object of the present invention is to solve such various problems. The drainage structure of the automatic ice maker according to the present invention includes the ice making unit, the ice making unit, and the ice making water supplied to the ice making unit. The water tank, the circulation pump that supplies the ice-making water in the ice-making water tank to the ice-making section, the communication member that connects the circulation pump to the ice-making water tank, and the drainage structure of the automatic ice maker have some features.

Description of the invention (10) (Please read the precautions on the back before filling in this page) 24 short ice cubes 52. Each ice-making tray 52 and the ice-making board 5 are made of copper or aluminum with good thermal conductivity. The cooling pipe 53 is bent and fixed on the upper side of the ice-making board 51 and passes through the center of each ice-making tray 52. The cooling pipe 53 is circulated and supplied. The refrigerant from the refrigerator in the machine room 71 cools the ice making tray 52. As shown in FIGS. 1 and 2, the ice skateboard 60 has a plurality of elongated slide members 61 arranged side by side in the longitudinal direction. The front and rear ends and the middle portion are connected by connecting portions 62a, 62b, and 62c. A pair of supporting leg pieces 63 in the horizontal direction are connected in a reed shape, and the whole is integrally formed of synthetic resin. The ice skateboard 60 is elastically connected to the outer peripheral surfaces of the two skateboard support cylinders 24 by a pair of supporting leg pieces 63, and is arranged in the ice-making part casing B downward from the upper side adjacent to the water spray nozzle 40. The ejection outlets 43 of the water spray nozzles 40 are arranged in a gap between the channel members 61, and the ice-making water ejected from each ejection outlet 43 is not disturbed by the ice slide 60. During the ice-making operation, the refrigerator is operated to cool each ice-making bin 52, and the ice-making water in the ice-making water tank 30 filled in advance to the overflow hole 34 is sucked in by the circulation pump 45 and supplied to the water spray nozzle through the water supply pipe 47 40. It ejects upward from each ejection port 43 toward each ice making tray 52. The sprayed ice-making water is sprayed into the cooled ice-making compartments 52 between the slide members 61 of the ice slide 60, and a part of the ice-making compartment is frozen inside, and the rest is returned to the ice-making water tank 30 by gravity. The water spray nozzle 40 is supplied again by the circulation pump 45. Since the water is repeatedly sprayed on the inner surface of the ice making tray 52, as time passes, the icing in each ice making tray 52 increases, and the ice making water in the ice making water tank 30 is also increased. It then decreases. When the ice making compartment 52 is substantially filled with ice, stop the ice making operation. If hot air is passed into the cooling pipe 53, the paper size applies the Chinese National Standard (CNS) A4 (210X297 mm) 13 557348 A7 B7 V. Description of the invention (η) The ice-making chamber 50 is matured, and the boundary between each ice-making compartment 52 and the ice made inside it starts to melt. The ice in each ice-making compartment 52 becomes a short cylindrical ice cube C and falls into Go to the ice skate 60 and slide down under the killer of the partition 25. The partition plate 25 which is naturally closed and closed due to gravity is automatically pressed and opened, and falls into the ice storage 72 from the case B of the ice making section. Then, a specified amount of ice-making water is supplied into the ice-making water tank 30 through a water supply pipe (not shown in the daytime), the refrigerator is started again, the ice-making chamber 50 is cooled, and the ice-making operation is repeated. In this embodiment, it suffices that the drainage bin has a size that can cover the circulation pump and the overflow hole 34 from the lower side, and if the ice-making water supplied to the ice-making water tank 30 is excessive, the excess ice-making water is located in the passage 37a. The straight overflow port 34 falls into the drain bin 37 through the passage 37a, and is discharged to the outside through the discharge port 72a at the bottom of the ice storage 72 through the discharge port and the drain pipe 39, so there is no need to connect the overflow pipe to the overflow hole 34. Therefore, the drainage structure of the automatic ice maker is compact and simplified. When the ice-making water tank 30 is removed for cleaning, the suction pipe 46 connected to the water supply port 33 through the easy-to-remove pipe joint 46a can be removed. It is only necessary to attach and detach from the water tank support groove 11 from below, which can reduce the trouble of assembling and disassembling. Furthermore, in the above embodiment, the drainage chamber 37 is formed with a passage 37a extending vertically through the partition wall 37b, and at the same time, the bottom of the drainage chamber 37 positioned directly downward is inclined downward toward the drainage pipe 39, and is connected to the bottom surface. A notch hole 37c is formed at the lower end of the partition wall 37b, so that the overflow hole 34 of the ice-making water tank 30 is opened directly above the passage 37a, and the drainage falling from the overflow hole 34 does not deviate sideways and pass through the passage 3 7 a It falls into the bottom surface of the drainage bin 37 and flows directly to the drainage pipe 39, and it does not jump out from the bottom surface of the drainage bin 37 and scatter. Therefore, set 14 (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 557348 V. Description of the invention (12) Electrical installed in the drainage compartment 37 The component's circulating pump shirt is not exposed to water, which reduces failures. In addition, in the 34 types of automatic ice makers, when the ice cubes in the ice storage 72 exceed a specified height, they are detected by the height detection switch, and the ice making P stops operating. If the south detection switch fails, , The circulation system is 4 $, but it will block with the rising ice cube. However, according to the above-mentioned embodiment, even if the Nandu detection switch fails, the lower side of the circulation pump 45 is protected by the drain bin 37 and will not be blocked by ice cubes, which can prevent a failure due to this reason. The above-mentioned only solution applies the present invention to an automatic ice maker having an open-form ice making section, but the present invention is not limited to this, as long as the ice-making water in the ice-making water tank is sucked in by a circulation pump The automatic ice maker provided to the ice-making section and returning the ice-making water not used in the ice-making section to the inside of the ice-making water may also be various types of automatic ice-making machines including the fourth prior art and the like. According to the present invention, since the lower side of the circulation pump is covered by a drainage bin made of synthetic resin with a drainage pipe connected to the bottom surface, water droplets that fall after dew condensation on the circulation pump casing or the leakage of the circulation pump are received by the drainage bin and removed from The drain pipe is discharged and will not fall into the lower machinery room or ice storage. Moreover, the water droplets formed by the moisture condensation on the drainage bin will not fall into the lower machinery room or ice storage. Therefore, such water droplets and oil leakage will not stain the lower machinery room, or adversely affect the machines inside it, nor will it cause the ice cubes in the ice store to melt, or the ice cubes will stick due to re-freezing. In some cases, the oil spill will not pollute the ice cubes in the ice storage. In addition, the drainage bin only needs to be 557348 A7 B7 V. Description of the invention (13) It is enough to cover the circulation pump and the overflow hole from the lower side, and the excess ice-making water overflowing from the overflow hole of the ice-making water tank 30 falls into It enters into the drainage bin and is discharged from the drainage pipe. There is no need to connect the overflow pipe to the ice-making water tank. Therefore, the drainage structure of the automatic ice maker can be compact and simplified. In addition, if the part of the bottom surface of the drainage tank that is directly below the overflow hole is sloping downward toward the drainage pipe, and the drainage falling into the drainage tank from the overflow hole flows directly to the drainage pipe, the situation of jumping out and scattering from the bottom surface of the drainage tank can be reduced, so , It can reduce the situation that the circulating pump of the electrical components is exposed to water. Further, if a part of the drainage tank is formed with a vertically extending passage through the partition wall, and at the same time, the overflow hole is opened directly above the passage part, a gap is formed in the lower end of the partition wall connected to the bottom of the drainage tank, and it falls into the overflow port. The drainage into the drainage tank will not deviate to the side, but the direction of falling into the bottom of the drainage tank and flowing into the drainage pipe through the passage can further reduce the situation that the circulating pump of the electrical components is exposed to water. 16 (Please read the precautions on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 (210X297 mm)
