Description

[Detailed description of the invention] This invention relates to a buried water ice making machine that produces buried water by freezing ice making water supplied to an ice making tank. The purpose is to prevent resonance of the ice removal tool due to machine vibration.

Conventionally, in this type of ice maker, a spiral ice removal device is fixed to a support plate installed in the upper opening of the ice making tank, or an ice removal device made of a wire bent into a U-shape is arranged inside the ice making tank. was.

However, although there is no problem with the former ice removal tool when taking out the ice immediately after ice making is completed, when taking out the ice after 1 to 2 days, for example, it is difficult to remove the ice if the ice near the ice removal tool has melted. The latter type of ice removal tool naturally has a width smaller than the inner diameter of the ice making tank, so it may resonate with components that generate vibrations such as a hermetic electric compressor, or cause damage to the inner surface of the ice making tank during resonance. It has the disadvantage that it makes noise when they come into contact.

This project not only lifts the ice from the bottom so that it can be taken out at any time regardless of its melting state, but also includes an ice removal tool that prevents noise caused by resonance with vibration-generating components. The company provides a buried water ice making machine.

An embodiment of the present invention shown in the drawings will be described below.

Reference numeral 1 denotes a main body of a block ice maker, and the main body has an ice making tank 3 with an open top opened and closed by a door body 2 at the top, and a machine room 4 at the bottom.

The ice making tank 3 includes an outer box 5 and a metal such as stainless steel or aluminum which is arranged at a distance from the outer box and has a refrigerant evaporation tube 6 and a dehydration heater 7 attached to the outer surface to form a freezing wall surface. An inner box 8, a synthetic resin mouth-shaped frame body 9 connecting the upper opening edges of the outer box 5 and the inner box 8, and both boxes 5, 8.
It is composed of a heat insulating material 10 filled with foam in between.

Also, inside the machine room 4 is a hermetic electric compressor 11 that constitutes a refrigeration cycle together with the refrigerant evaporation pipe 6 attached to the inner box 8.
．． A condenser 12 and an electric blower 13 for cooling the condenser are arranged and housed.

Reference numeral 14 denotes a support plate detachably installed on the annular stepped portion 15 of the mouth-shaped frame body 9, and an air blowing pipe 16 is fixed at the center of the support plate.

The door body 2 is filled with a heat insulating material 17 and an air pump 1
8 and a pressure switch 19, and the suction port 2 of the pump.
0 and a discharge pipe 21 are provided on the inner side, and a rubber gasket 22 is attached to the discharge pipe 21 so as to connect it airtightly with the air blow-off pipe 16 when the door body 2 is closed.

23 is an abbreviation U which is removably installed in the ice cream tank 13.
It is a letter-shaped ice removal tool, and the ice removal tool is made by bending a stainless steel wire rod or plate material having spring properties and has a handle portion 24 at the upper end.
Opposing sides 25, 25 and base 26t forming 24
26.

The ice removal tool 23 has a width A of the base 26.26 slightly smaller than a bottom dimension B of the inner box 8, and a width A of the upper side 25, 25, that is, a width A of the upper part of the inner box. The ice making tank 3 has a membrane deformed as shown by the two-dot chain line in Figure 3, and is inserted into the inner surface of the inner box 8 in a pressed manner. It is to be installed.

Further, the handle portion 24.24 formed at the upper end is formed so as to be located slightly toward the center so that it can be easily inserted when lifting.

Next, the ice making operation and dewatering operation in the above configuration will be explained.

First, ice making water is supplied into the ice making tank 3 up to the water level line 27.

This ice-making water is cooled by the refrigerant evaporation pipe 8 by operation of the refrigeration cycle, and air is blown from above through the air blow-off pipe 21 into the ice-making water by the operation of the air pump 18, and this air circulates while stirring the ice-making water. .

Due to the falling, transparent ice begins to form around the inside of the ice making tank 3 and grows until the air blowing pipe 21 is blocked and the pressure switch 19 is turned off.

When the ice-making operation is completed, the operation of the refrigeration cycle is stopped by the ice-making and dehydrating thermostat, and the dehydrating heater 7 is energized to melt the outer surface of the ice.

Next, after removing the support plate 14, when the handle portions 24, 24 of the ice removal device 23 are lifted up with both hands, the transparent buried water is removed from the ice making tank 3.

After moving this buried water to a suitable ice storage place, the ice removal tool 23
This is to remove the .

As described above, the buried water ice maker according to the present invention has an ice making tank that freezes supplied ice making water, and has handles formed at both ends of the upper part by bending a member having spring properties such as stainless steel. Since it is equipped with a letter-shaped ice removal device, it is possible to lift the buried water from the bottom, making it possible to remove the buried water reliably and easily. Moreover, by making the width of the upper part larger than the width of the upper part of the ice making tank, the upper part of the ice removal tool is placed in a pressed state against the inner surface of the inner box of the ice making tank. movement due to vibration,
Resonance and noise generated by contact with the inner box at the time of resonance can be prevented.

Further, when removing the ice removal tool from the water, it can be easily removed by expanding the upper part of the ice removal tool from side to side, and since the ice removal tool has spring properties, it returns to its current shape after being expanded.
