【発明の詳細な説明】
この発明は家庭用電気冷蔵庫の冷凍室に於て透
明の氷を作る場合に空気吹込みパイプを使用し、
その周囲にニクロム線などの熱線を設け低電圧の
電流を流しパイプの周囲の凍結を防ぎ透明の氷を
作る事を目的としたものである。[Detailed Description of the Invention] This invention uses an air blowing pipe when making transparent ice in the freezer compartment of a household electric refrigerator.
The purpose is to create transparent ice by installing a hot wire such as a nichrome wire around the pipe and passing a low-voltage current to prevent the area around the pipe from freezing.
家庭用電気冷蔵庫の普及で冷凍室内で作る氷は
白く雲つた氷しか出来なかつた。何故透明の氷が
出来ないのか要望は強かつたが、現在考案されて
いる物は電気モーターを使用し給水容器を回転或
は反復運動の方法など構造が複雑で製造費が高価
額のためか一般に普及しなかつた。 With the spread of household electric refrigerators, the only ice made in the freezer was white cloudy ice. There has been a strong demand as to why transparent ice cannot be produced, but the products currently being devised use an electric motor to rotate or repeatedly move the water container, and are complex in structure and expensive to manufacture. It did not become popular to the general public.
この発明は家庭用電気冷蔵庫の冷凍室内で作る
事の出来る大きな亦構造も比較的簡単、それに低
価額で製造出来る。 This invention has a relatively simple structure and can be manufactured at low cost, even in a large refrigerator that can be manufactured in the freezing chamber of a household electric refrigerator.

残り氷上面の盛り上りは最大となり製氷された氷
は白く雲り不透明となる美観がおこなわれる。 Conventionally, when making ice in the freezer compartment of a household electric refrigerator, water is supplied to an ice tray and the water is placed inside the freezer compartment to make ice.In this case, when ice is being made, freezing starts from all directions, including the sides, bottom, and top of the ice tray. At the initial stage, the frozen parts on the lower side and upper surface are transparent. However, expansion, a natural phenomenon that occurs when water turns into ice, begins when the temperature at the center of the water falls below 4 degrees Celsius, where water has the highest specific gravity. When expansion begins, the expansion force is very strong and acts from the center in all directions. At this time, since the side and bottom surfaces are the strong containers of the ice cube tray, the expansion force acts only in the upward direction, and until expansion begins, the transparent ice on the top surface is pushed up from the bottom to the top, creating bubbles. In addition, water usually contains some gaseous impurities such as air, and when the water is frozen to the center, the air and other gases contained in the water are separated from the ice, giving the gas buoyancy. Even if the upper part is frozen, it will not be possible to release it to the outside, and this action will be repeated until the center is completely frozen, remaining as bubbles, and the bulge on the top of the ice will reach its maximum, and the ice that is made will become a white cloud. Aesthetics that is opaque is performed.

給水した水の中心部深くまで空気を吹込むため銅

ながら製氷している。 This phenomenon occurs because the water in the ice tray remains stationary during ice making. Therefore, in order to prevent the opaque phenomenon, ice making factories, etc. insert copper pipes to blow air deep into the center of the water supplied to the ice making can, and blow compressed air into the ice making can while stirring the water while making ice.

透明の製氷は不可能となる。 In this invention, water is supplied to a slightly deep container 1 in the freezing chamber of a household electric refrigerator, and an electromagnetic pump attached to the inner part of the lid 4 and an air blowing pipe provided in the center are used to supply water to the container 1. This method blows air (cold air) at a temperature of -15°C to -20°C inside the freezing chamber, but this method does not allow air to flow inside or outside the air outlet of the pipe inserted into the center of the water in the early stages of freezing. Regardless of whether the inner diameter of the pipe is large or small, ice builds up and it becomes impossible to blow air into the pipe, making it impossible to make transparent ice.
前述の実施例で結氷附着を防止する方法として

製氷を可能にしたのがこの方法である。 In the above-mentioned example, as a method of preventing ice formation, the air (cold air) outlet was used to generate a small amount of heat using a heating element, thereby preventing the air outlet from freezing and making it possible to make transparent ice until the freezing was completed. It is.

された水の中に吹込む。 Now, to explain the embodiment in detail with reference to FIGS. 1 to 5, water is supplied to the ice making container 1 shown in FIG. 1 up to the line 2, and the plate 3 shown in FIG. Place lid 4 on top of 1 and make ice.
A double pipe 5 is attached and fixed to the horizontal center of the plate 3 shown in FIG. 2, and the lowermost part is inserted into the water from the line of the water 2 supplied. In the drawing of one side of the plate 3 in Figure 1, an electromagnetic pump and a double micro switch 10 are installed on the left side, and in the drawing, a transformer (primary 100 volts AC secondary 10 volts AC) is installed on the right side.
Electromagnetic pumps have the same structure as aquarium pumps used for tropical fishing and other purposes, and utilize the vibrations of permanent magnets using electromagnets. 8000 pieces of coated copper wire with an ultra-fine diameter of 0.1 mm is attached to the iron core 6 in Figure 2.
By applying 100 volts of AC household electricity to the wound coil 7, magnetic force is generated at both poles of the iron core 6, and the permanent magnet 8 approaching the both poles of the iron core 6
vibrates in the direction of both poles. The pump operates due to the vibration of the permanent magnet 8, but the pump is operated by the cylinder 9 in Figure 2.
The cylinder 9 has an intake valve and an exhaust valve built into it.
A circular rubber 11 is placed over the cylinder 9, and the cylinder 9 and the circular rubber 11 are in close contact with each other. A rubber plate 14 is attached to the fulcrum 13 of the permanent magnet 8, and an L-shaped arm 15 shown in FIG. The L type 15
The center 16 of the circular rubber 11 is fixed with a screw to the middle of the arm. By energizing the coil 7 wound around the iron core 6, magnetism is generated at both poles of the iron core, and since the electricity is alternating current, the permanent magnet 8 vibrates, causing the circular rubber 11 fixed to the arm of the L-shape 15 to vibrate. Air pressure is generated in the cylinder 9, and the air pressure is passed through the vinyl pipe 14 from the exhaust port 12, and then through the air intake port 17 at the top of the inner pipe 16 of the double metal pipe in FIG. 5, and the air at the bottom of the pipe 16. It is blown into the water supplied from the spout 18.

する事が出来る。 However, if air is simply blown into the water supplied by the air pressure of the electromagnetic pump, the air blown from the air outlet 18 of the double pipe 5 at the initial stage of ice making will reach a temperature of -15°C to -20°C in the freezing room. Due to the cold air, the area around the spout 18 was covered with ice as indicated by the dotted line 19 in Fig. 5, and as a result of several examples, the only pipe inserted into the water surface 2 was initially the pipe 16, but the inner diameter of the pipe 16 Regardless of whether it is large or small, ice builds up and makes it completely impossible to blow in air, making it impossible to make transparent ice. Therefore, the part where the heating element is installed to prevent ice formation at the air outlet 18 will be explained in detail with reference to FIG. Manufactured using methods such as gluing or welding to prevent infiltration. A heating element 21 is installed all the way to the bottom in a small space between the pipes 5 and 16, and the heating element 21 is made of a hot wire such as nichrome wire covered with an insulating material such as bisque or asbestos, and in this embodiment, it is a commonly available commercially available material. I am using a 30 watt heater on my soldering iron. Circuit wires 22 and 23 from the nichrome wire of the heating element 21 are brought out above the stopper 24. The upper part of the pipe 5 is attached to the plate 3 with a stopper 24.
The top of the inner pipe 16 is fitted with a plug 24 to prevent air from escaping upward from the air intake inlet 17.
Closely adhere to. Circuit wires 22, 23 from heating element 21
In the example, if a low voltage of 10 volts is applied to make ice, a small amount of heat will be generated from the heating element 21 even if cold air of -15°C to -20°C is blown into the freezer compartment, resulting in the dotted line 1 in Figure 5.
The temperature of the part 9 can be maintained at 0°C to 2°C to prevent freezing and adhesion.

1図の点線25のように水面2の線より盛り上り

の心配が全くない。 By blowing air into the water during ice making, the air forms bubbles on the water surface from the spout 18 at the bottom of the pipe 16, and while stirring the water itself, impurities such as gases contained in the water are released to the upper part. This action works until the freezing is completed, and when the freezing is completed, the surroundings of the double pipe 5 are frozen and transparent ice can be made. In addition, the expanding portion of the ice rises above the water surface 2 as indicated by the dotted line 25 in FIG. 1, and the expansion force does not act on the sides, so there is no fear of damage to the ice making container.

ている。 The next step is to take out the ice cubes from the ice making container 1. Since ice is frozen around the double pipe 5, it is difficult to remove the lid 4. Therefore, 100 volts of electricity is applied to the circuit wires 22 and 23 of the heating element 21 using a changeover switch of a dual micro switch.
generates high heat, and the frozen parts around and below the double pipe 5 melt, making it easy to remove the lid 4, and when the melted ice is taken out from the ice making container 1, transparent ice is formed.

It is warmed by the heat of

Even if the water becomes frozen and starts freezing from both sides and the bottom, the temperature of the unfrozen part remains +2
kept at ℃. The effect of preventing the water from freezing occurred.

ている。 As freezing progresses from both sides and the bottom,
Even if the water in the unfrozen part gradually decreases and the cold air discharge area to the water surface gradually decreases, the amount of cold air passing through the pipe 5 in which the heating element 21 is installed is The smaller the remaining amount of water, the more efficiently it can be heated, and the effect is that the temperature of the remaining water is kept at +2°C until the ice making is completed.

た。 During ice making, the cold air blown into the unfrozen portion of the water kept at +2℃ is released to the water surface, so impurities contained in the water such as gas are released to the top, and this action continues until the freezing is complete. It is now possible to make ice cubes.

い。 In addition, when water turns into ice, the expanding part is released onto the water surface by blowing cold air, so the expansion force does not work on the side and bottom parts, and as shown by the dotted line 25 in Figure 1, the expanding part is released onto the water surface. It rises above the line and has a strong expansion force, so there is no need to worry about deformation or damage to the ice making container.
