The present invention relates to a raw material water supply structure of a drum ice maker with easy management and improved hygiene.

The ice making drum is rotated while the ice making drum supplied with the refrigerant through the cooling cycle A is immersed in the ice making plate to freeze ice on the surface of the ice making drum, and the ice produced on the surface of the ice making drum is ground with a blade. Prepare ice.

Conventionally known drum ice makers are known, such as Patent No. 10-1384482, the contents are provided with a supply pipe is installed in the raw material water supply fan, the fixing body for the solenoid valve operation is installed integrally on the supply pipe, An ice making drum is installed on the lower space, and the ice making drum is disposed in a state of being partially immersed in an ice making object such as an aqueous solution such as an aqueous solution such as water, milk or coffee solution. The lower end of the supply pipe is connected to the upper part of the ice making pan to supply the object to be iced on the supply fan to the ice making pan, and the ice making pan detects an appropriate level through a water level sensor, and based on the fixed body By controlling the opening and closing of the associated solenoid valve, the fluid to be iced is adjusted to maintain a constant level on the ice making fan at all times. In addition, an ultraviolet sterilization lamp is installed on the inner wall surface of the main body case to prevent germs propagating in the space between the ice making drum and the ice making pan, and the ultraviolet sterilizing lamp emits a germicidal line of 185 nm, and various pathogens including Escherichia coli and It is a known lamp having a function of sterilizing bacteria.

In particular, a funnel catchment guide is provided to collect and discharge the wash water used by the washing unit, and the funnel catchment guide is configured to be pulled forward after the cover is opened, and the funnel catchment guide is drawn out. You can also clean the inside with a small shower or air jet like a handgun.

A washing unit is provided to improve hygiene in hygiene, and the washing unit includes a washing water distribution pipe forming a circular or rectangular shape at a lower position of the supply pan, that is, an upper side of the ice making drum, and the washing water distribution pipe faces the ice making drum. A plurality of washing water spray nozzles for spraying washing water are installed. The washing water supply pipe is connected to the washing water supply pipe for supplying the washing water, the washing water opening and closing valve is installed in a part of the pipe of the washing water supply pipe, the end of the washing water supply pipe is connected to the washing water supply pump is a problem of contamination due to raw water Add a cleaning structure to have a complex structure to solve.

In addition to these ice makers, a common problem in general ice makers is that, as also shown in the above patent, a raw water supply pipe for supplying raw water to an ice making plate in which a drum is immersed in a pan (raw water tank) for supplying raw water. Connected. Such a water supply pipe is conventionally coupled to a supply pan (raw material tank) by a screw fitting structure, so that there is a risk of contamination due to contaminants caught in the spiral grooves, and leakage occurs between the spiral grooves of the screw fitting portions. Since the packing must be inserted at the outside before and after the groove, the packing was frequently lost during the process of separating and assembling the opening / closing valve.

In particular, when the raw material tank and the shut-off valve is conventionally combined, there is a management problem in that the washing of the tank and the opening / closing means are possible only by disassembling one by one. Furthermore, it is impossible to store the remaining raw water in the tank and store it in the refrigerator. It was. In addition, the management of each drum ice maker installation operation was cumbersome due to the disassembly, and there was also a cumbersome hygienic problem of cleaning the valve as well as the internal cleaning of the tank.

On the other hand, if the ice making state of the ice making drum surface is evenly iced to a certain thickness can obtain a good snow ice. Since the ice plate immersion state of the ice making drum to obtain such excellent snow ice determines the surface immersion of the ice making drum, the water supply structure of the raw water supplied to the ice making plate cannot be ignored. Conventionally, it was only a hose, without considering the length of the water supply pipe to the ice making plate, the structure of the water supply pipe, and the like. This is because an ice making control with an ice making drum must be made to stop or supply water by pressing a portion of the hose as a solenoid valve.

In addition, the raw water for ice making of the drum-type ice maker should be supplied in an amount that is consumed in the ice making drum so that the problem of residues caused by the residual water does not occur. In other words, in order to supply the raw water according to the amount of raw material consumed in the ice making drum, a method of automatically adjusting the amount of raw water for ice making according to the change of the level of the ice making plate is applied. In order to do this, it is necessary to control the water level detection device and the raw material water supply device, and thus, the space required for the water level detection in the ice making plate is required.

In addition, the water level can not be used hygienically due to the generation of residual water after the use of raw water for ice making filled in the ice tray, and the water stays for a certain period of time as the static state of the ice making drum. The raw material water causes an unsanitary and fatal problem of deterioration.

The present invention is advantageous in compacting the size of the casing by eliminating (reducing) the space required for water level detection in the ice making plate, improving the problem of deterioration of the raw water according to the residual water remaining in the ice making plate, and the water level of the ice making plate. The aim is to provide a simpler feedwater supply structure with improved sensing.

The present invention is to prevent the contamination of the spiral groove by screwing the raw water tank and the drain pipe for the conventional raw material water supply (improving the screw coupling structure), and the packing for preventing leakage through the spiral groove of the screw fitting portion The purpose is to improve the assembly.

In the present invention, when the raw material water tank and the on-off valve (drainage pipe) are combined, it is necessary to disassemble the on-off valve one by one to improve the management problem that the washing of the raw water tank as well as the opening / closing means is possible. The purpose is to make it very simple to separate the drain pipe from the raw water tank.

An object of the present invention is to provide a raw material tank which can be stored in a refrigerator or the like while remaining in the raw material tank without discarding the remaining raw water (particularly, fruit raw water).

It is an object of the present invention to provide a raw material water draining means of a drum ice maker in which a fixed amount of water is discharged by manual operation rather than an automatic control method in which the drainage of raw water is in close contact with the hose.

Ultimately, the present invention is troublesome for the administrator of the drum ice machine installation and operation, and furthermore, the raw water supply of the drum ice machine with improved management and hygienicity is improved by improving the cumbersome hygienic problem of washing the valve as well as the internal cleaning of the tank.

7A is a perspective view of a state in which raw water is being supplied in a storage tank of a raw water supply structure of a drum ice maker that is easy to manage and improve hygiene of the present invention, and FIG. 7B is a drum of which the present invention can be easily managed and improved in hygienicity. Fig. 8A is a perspective view showing a state in which an on-off valve is folded to store the remaining raw water of the storage tank of the raw water supply structure of the ice maker, and Fig. 8A shows the raw water supply structure of the drum ice machine, which is easy to manage and improved hygiene of the present invention. 8B is a front schematic view of a state in which raw water is being supplied in a storage tank, and FIG. 8B is folded to close and close a valve to store and use the remaining raw water of a storage tank of a raw water supply structure of a drum ice machine that is easy to manage and improve hygiene of the present invention.

9A and 9B are schematic explanatory diagrams for explaining a raw water supply state in a storage tank of a raw water supply structure of a drum ice machine with which the present invention can be easily managed and improved hygiene. Since the immersion state (depth depth) of the ice making drum may affect the amount of drainage, it is preferable that the shape of the ice making dish is set to the length of the drain pipe portion to the bottom of the dish as shown in this drawing. The length of the drain pipe portion of the ice making plate is preferably set to the height of the water surface forming a semi-circular curved surface, not the bottom of the dish. In addition, when the length of the drain pipe portion 30 is short, the flow rate change may be more severe. When the flow rate change is large, a change in the water level of the ice making plate 11 occurs, and a change in the depth of deposition (immersion) of the ice making drum 12 is generated by this water level change, thereby contacting the raw water for ice making. A change in surface condensation (de-icing) of the ice-making drum 12 is generated, and then a change in the freezing load is generated, and the temperature of the raw water for ice-making which is formed on the ice-making drum 11 is changed by this freezing load. This will result in the most severe ice quality change in the drum ice maker, thus losing the purpose of the drum ice maker as a simple and simple ice maker. The flow rate is defined as the product of the flow rate through the nozzle to the cross sectional area of the nozzle being passed through.

That is, as known, Q = A (nozzle cross section) x V (flow rate)

The velocity V in the gravitational pull-off equation can be calculated using the Bernoulli equation,

Bernoulli's equation is: H + P / γ + (V × V) / (2 × g) = 0

Where H; Free fall height, P: fluid pressure in the pipeline, γ: specific gravity of the fluid,

       V is the velocity of the fluid and g is the acceleration of gravity.

What we are trying to find is V, the velocity of the fluid, and the specific gravity γ of the fluid and the fluid pressure P (constant, excluded)

 Since V = √ (2 × g × H), the flow rate Q is

 Q = A × √ (2 × g × H),

Where the flow rate Q is changed by √H (since A, 2, and g are constant constants).

Now, when comparing the above described with reference to Figure 8a, 8b and Figure 1a,

In the case of Fig. 8a, 8b, when the ice-making raw material in the ice-making raw material tank is compared with the ice-making raw material flow in the case of full water level and low water level,

 Full water level Q = A × √ (2 × g × c), c = a + b

Low Water Flow Q '= A × √ (2 × g × c') c '= a' + b

If a = 20 and b = 20 a '= 1, the ratio of flow rate Q and Q' is

Q / Q '= (√c) / (√c') = (√40) / (√21) = 6.324 / 4.582 = 1.38 = 138%

In the case of Figure 1a, when the ice-making raw material in the ice-making raw material tank compared the ice-making raw material flow in the case of full water level and low water level,

Full water level Q = A × √ (2 × g × d), d = a + b '

Low Water Flow Q '= A × √ (2 × g × d') d '= a' + b '

If a = 20, b '= 1, a' = 1, the ratio of the flow rate Q and Q 'is

Q / Q '= (√d) / (√d') = (√21) / (√2 ') = 4.582 / 1,414 = 3.169 = 317%

Becomes

Therefore, in the raw water storage tank, the flow rate change ratio Q / Q 'is larger under the condition of the same water level change (Δa = a-a') than in FIGS. 8A and 8B. Can be. Therefore, the length of the drain pipe portion 30 of the raw water supply structure of the drum ice maker, which is easy to manage and improved hygiene of the present invention, is advantageously long, as shown in FIGS. 8A and 8B (the storage amount inside the drain pipe portion is minimal). Subject to acting only as a pathway). That is, the drain pipe part 30 may form a space 303 of predetermined lower narrow light whose diameter becomes narrower as the upper and lower ends thereof move downward, as shown in FIG. 6A, and the upper and lower opening diameters of FIG. The same cylinder can be achieved. The drain pipe portion 30 of the present invention is preferably formed with a maximum length (a) between the ice tray in the second slip insertion portion 23 of the on-off valve (20).
