Description

Water supply apparatus for drum type ice machine with Easy Maintenance and Improved Sanitanity

The present invention relates to a raw material water supply structure of a drum ice machine, in particular, to secure space by removing the water level detecting means in the ice making dish, and structure to combine the raw material water tank (hereinafter referred to as a storage tank) and a drain pipe by screwing. Improves the prevention of spiral groove contamination, and it is easy to separate the opening and closing valves as well as the drain pipe of the opening / closing valve from the storage tank, and keep it in a refrigerator or the like in the storage tank without leaving raw water (especially fruit raw water). This relates to a structure for supplying raw water to a drum ice maker with easy management and improved hygiene.

The ice making drum rotates the ice making drum supplied with refrigerant through the cooling cycle (A) while immersed in an ice tray to freeze ice on the surface of the ice making drum, and grinds the ice generated on the surface of the ice making drum with a blade. Make ice.

The conventionally known drum ice machine is known as Patent No. 10-1384482, the contents of which are provided with a supply pipe to a raw material water supply fan, and a fixed body for a solenoid valve operation is integrally installed on the supply pipe. An ice-making drum is installed on the lower space, and the ice-making drum is disposed on the ice-making pan in a state of being partially immersed in an ice-making fluid in the form of an aqueous solution such as water, milk, or an aqueous coffee solution. The lower end of the supply pipe is connected to the upper portion of the ice-making fan to supply the de-icing fluid accommodated on the supply fan to the ice-making fan. The ice-making fan detects an appropriate water level through a water level sensor and based on this, the fixed body and By controlling the opening and closing of the associated solenoid valve, the fluid to be iced is adjusted to always maintain a constant water level on the ice making fan. In addition, a UV sterilization lamp is installed in place on the inner wall surface of the main body case to prevent germs from propagating in the space between the ice-making drum and the ice-making fan, and the UV sterilization lamp is a lamp that radiates a sterilization wire of 185 nm, and various pathogens including E. coli and It is a known lamp that has a function of sterilizing bacteria.

In particular, a funnel-type water collecting guide is provided to collect and discharge the washing water used by the washing unit, and the funnel-type water collecting guide is configured to be able to be pulled forward after the cover is opened, and the funnel-type water collecting guide is withdrawn. You can also clean the inside using a small shower, such as a handgun, or an air jet.

In order to improve hygiene and cleanliness, a washing unit is provided, and the washing unit includes a washing water distribution pipe forming a substantially circular or square shape on the lower side of the supply fan, that is, an upper side of the ice making drum, and the washing water distribution pipe toward the ice making drum. A number of washing water spray nozzles for spraying washing water are installed. A washing water supply pipe capable of supplying washing water is connected to the washing water distribution pipe, a washing water opening / closing valve is installed in a part of the pipe of the washing water supply pipe, and a washing water supply pump is connected to the end of the washing water supply pipe, such as contamination problems caused by raw water. It has a complicated structure to be solved by adding a cleaning structure.

In addition to these ice makers, a common problem with common ice makers is that, as shown in the above patent, a raw material water supply pipe for supplying raw material water to an ice-making dish in which a drum is immersed in a fan (raw material tank) for supplying raw material water is provided. Connected. Since these water supply pipes are conventionally combined with a screw fitting structure to a supply fan (raw water tank), there is a risk of contamination due to contaminants trapped in the spiral grooves, and leakage occurs between the spiral grooves of the screw fittings. Since the packing must be inserted on the outside before and after the groove, the packing was frequently lost in the process of separating and assembling the on / off valve when washing the raw material tank.

Particularly, when the conventional raw water tank and the opening / closing valve were combined, there was a management problem that the cleaning of the water tank and the opening / closing means had to be disassembled one by one. Moreover, it was impossible to store the remaining raw water in the water tank in a refrigerator or the like. Did. In addition, the manager of each drum ice machine installation and operation was cumbersome due to disassembly, and there was also a cumbersome hygienic problem of cleaning the inner and outer valves of the water tank.

On the other hand, if the ice-making state on the surface of the ice-making drum is uniformly iced, good ice-making can be obtained. Since the immersion state of the ice tray to obtain such excellent snow ice determines the surface immersion of the ice tray, the water supply structure of the raw material water supplied to the ice tray cannot be ignored. Conventionally, the length of the water supply pipe to the ice-making dish, the structure of the water supply pipe, and the like are not considered, and are merely hoses. This is because, as a solenoid valve, de-icing control with the de-icing drum must be made to stop or supply water by pressurizing part of the hose.

In addition, the raw material for ice-making in the drum type ice maker should be supplied in an amount consumed by the ice-making drum, so that there is no problem of debris generation due to residual water. That is, in general, in order to supply raw water according to the amount of raw materials consumed in the ice-making drum, a method of automatically adjusting the amount of raw water for ice-making is applied according to a change in the level of the ice-making dish. In order to do this, it is necessary to control the water level detecting device and the raw material water supply device, and thus, a space required for detecting the water level in the ice-making dish is required.

Also, due to the detection of the water level, after the use of the raw material water for ice-making, which is filled in the ice-making dish, the raw water becomes unusable for hygiene and the raw material water remains in the stationary state of the ice-making drum for a certain period of time. The raw material water causes deteriorating unsanitary and fatal problems.

In the present invention, it is advantageous to compact the size of the casing by reducing the space required for detecting the water level in the ice-making dish, improve the problem of deterioration of raw water according to the residual amount after use in the ice-making dish, and improve the water level sensing method of the ice-making dish Another aim is to provide a simpler water supply structure.

The present invention prevents contamination of the spiral grooves by screwing the raw material water tank and the drain pipe for supplying raw material water by screw fitting (improvement of the screw fitting coupling structure), and packing to prevent leakage through the spiral grooves of the screw fitting part. The aim is also to improve assembly.

In the present invention, when the conventional raw water tank and the opening / closing valve (drain pipe) are combined, the opening / closing valve must be disassembled individually to improve the management problem that the raw material tank can be cleaned as well as the opening / closing means. The purpose is to make it very simple to separate the drain pipe from the raw water tank.

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

An object of the present invention is to provide a raw material water draining means of a drum ice machine in which a constant amount of water is drained by a manual operation rather than an automatic control method in which the drainage of the raw material water is electrically closed and opened.

The formation of the flanges 221 and 231 in the opening / closing valve 20, the flange 105 of the storage tank 10 and the flanges 305 of the drain pipe part 30 twist the opening / closing valve 20 when separating or assembling. This is because, when slipping and separating and slipping and inserting into the outlet 106 or the inserting portion 301 at the same time, the correct degree of insertion is quickly determined. In particular, the sealing member of the drum ice maker with easy management of the present invention and improved hygiene can be implemented as shown in FIG. 10. The sealing member is composed of a ring-shaped sealing body (223) (233), a sliding blade (223a) (233a), and a groove portion (223b) (233b). The grooves 223b and 233b are leaking fluids in which the sealing bodies 223 and 233 contact the sliding blades 223a and 233a, and have adhesiveness, and the grooves 223a, due to the elasticity of the elastic member 28 ( In 233a), it is possible to maintain a close contact state in the sealing grooves 222 and 232 with an expansion force.

Meanwhile, an injection path 211 is formed inside the first slip-insertion portion 22 of the valve body 21, an exhaust path 212 is formed inside the second slip-insertion portion 23, and an injection path 211 is provided. And the discharge path 212 form a valve stem 272 in the operation path 213 where the valve body 21 meets at a right angle inside the valve body 21, so that the valve body 27 is rotatably positioned. The lower end opens and closes the through hole 214 to open and close the supply of raw water so that the locking end 273 is formed so as to be caught by the locking jaw 215 of the valve body 21, and the valve body 27 is a valve stem 272 ) Is formed to extend upward and pull, and the upper part of the valve stem 272 forms a stem head 271, and the end thereof may be rotatably supported by an axial pin 253 on the head 252, which will be described later. So that a through hole (sign omitted) can be formed. An elastic member 26 may be attached to the operation furnace 213 to elastically suppress the lifting operation of the valve stem 272.

In addition, a flange 105 corresponding to the flange 221 of the first slip-insertion portion 22 of the valve body 21 is formed in the outlet 106 of the storage tank 10, and the drain pipe portion 30 A flange 305 corresponding to the flange 231 of the second slip insertion portion 23 of the valve body 21 may be formed at the upper end. The formation of the flanges 105, 221, 231, and 305 facilitates management of the present invention and improves hygiene and improves the opening / closing valve 20 of the drum ice machine to the storage tank 10, and the opening / closing valve 20 When inserting and assembling the drain pipe portion 30 to the second slip-insertion portion 23, it can be properly inserted and fixed by twisting and sliding until it quickly contacts the flanges.

The upper side of the valve body 21 is sealed as a cover 24, and the coupling structure can be screwed to a predetermined position of the valve body 21 and a spiral formed therein. The cover 24 forms a central hole (not shown) in the middle, so that the upper stem head 271 of the valve stem 272 can be supported by the head 252 of the handle 25.

The handle 25 is composed of a gripping portion 251 and a head 252, and the head 252 uses the stem head 271 of the valve body 27 on the top surface of the cover 24 and the shaft pin 253 in the head 252. ), It can be moved up and down by the up and down operation of the handle (25).

Meanwhile, the first and second sealing members 223 and 233 are means for preventing leakage and slipping at the same time. In particular, it is possible to implement a sealing member as shown in Figure 10 to perform the leak prevention function.

That is, in the present invention, the sealing grooves 222 and 232 may be embodied in a semi-circular cross section, and the first and second sealing members 223 and 233 inserted therein may also be circular cross-sections, but illustrated in FIG. 10. It can also be carried out in the cross-sectional shape of the sealing member. That is, the ring-shaped first and second sealing members 223, which form a slip contact surface on which one side slips without leaking into the outlet portion 106 of the storage tank 10 and the insertion portion 301 of the drain pipe portion 30 (( 233) can be inserted into the slip grooves 222 and 232, one side of the sealing member 223 and 233 forms grooves 223b and 233b, and the grooves 223b and 233b Inside, the flexible contact wings 223a and 233a are formed to close the leakage fluid through the outlet 106, and the elastic members 28 can be respectively inserted into the grooves 223b and 233b. Therefore, the inner walls of the grooves 223b and 233b can be brought into close contact with the elastic force of the elastic member 28, and the grooves 223b and 233b are respectively brought into close contact with the sealing grooves 222 and 232, thereby sealing the raw grooves 222 ) 232 can prevent leakage.

The drain pipe part 30 has a structure extending downward in a cylindrical shape of the on / off valve 20 as shown in FIGS. 6A and 6B, and the upper end forms an opened second slip inserting part 23, and this second slip inserting part 23 ) To form the insertion portion 301 so as to slide, form a flange 305, the lower end forms a shape blocked by the bottom 302, forms a space 303 between the upper and lower ends, and the bottom 302 ) A nozzle hole 304 may be formed at the center to discharge a certain amount of raw water.

A flange 105 corresponding to the first slip inserting portion 22 of the body 21 is formed at the outlet 106 of the storage tank 10, and the body 21 is disposed at an upper end of the drain pipe portion 30. It is preferable to form a flange 305 corresponding to the second slip insertion portion (23).

7A is a perspective view of a state in which raw material water is being supplied in a storage tank of a raw material water supply structure of a drum ice maker with easy management and improved hygiene of the present invention, and FIG. 7B is a drum with easy management of the present invention and improved hygiene. It is a perspective view showing a state in which the on-off valve is folded to store the remaining raw water of the storage tank of the raw material water supply structure of the ice maker after use, and FIG. 8A is a view of the raw material water supply structure of the drum ice maker with easy management and improved hygiene. It is a front schematic view of the state of supply of raw water in the storage tank, and FIG. 8B is a folding valve that opens and closes the valve to store the remaining raw water of the storage tank of the raw material water supply structure of the drum ice machine with easy management and improved hygiene. It is a front schematic view showing the state.

As shown in the drawings, the opening / closing valve 20 may be rotated at a right angle from the outlet 106 integrally with the drain pipe part 30, and a storage tank ( By simply slip-inserting in 10), it is possible to provide a raw material water supply structure of a drum ice maker that can be quickly assembled and has easy-to-manage and improved hygiene.

Meanwhile, FIGS. 9A and 9B are schematic explanatory diagrams for explaining the state of supply of raw water in the storage tank of the raw material water supply structure of the drum ice maker with easy management and improved hygiene. As in accordance with this figure, the immersion state (depth of deposition) of the ice making drum may affect the amount of drainage, so it is preferable to set the shape of the ice tray to the length of the drain pipe to the bottom of the dish. It will be desirable that the length of the drain pipe portion of the ice-making dish is set to the height of the water surface forming the 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 severe. When the flow rate change is large, the water level change of the ice-making dish 11 occurs, and the change in the depth of immersion (immersion) of the ice-making drum 12 is caused by the water level change, thereby contacting the raw material water for ice-making. A change in surface condensation (de-icing) of the de-icing drum 12 occurs, followed by a change in the freezing load, and the temperature of the raw material water for ice-making implanted in the de-icing drum 11 is changed by the freezing load. This may lead to the most serious change in ice quality in the drum ice machine (snow machine), which may lose the purpose of the drum ice machine as an excellent and simple simple ice machine. The flow rate is determined by the product of the cross-sectional area of the nozzle passing through and the flow rate through the nozzle.

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

In the gravitational equation by the drop, the flow velocity V can be calculated by the Bernoulli equation,

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

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

       V: fluid velocity, g: gravity acceleration.

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

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

 Q = A × √ (2 × g × H),

Here, the flow rate Q is changed by √H (because A, 2, and g values are constant).

Now, comparing the above Figures 8a, 8b and Figure 1a,

8A, 8B, when comparing the ice-making raw material flow rate when the ice-making raw material is in the high water level and the low water level in the ice-making raw material tank,

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

Low water flow Q '= A × √ (2 × g × c') c '= a' + b

If a = 20, 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, if the ice-making raw material in the ice-making raw material tank is compared to the case of the full water level and the case of the low water level, the ice-making raw material flow rate is compared,

Full water flow 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 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 large in the condition of the same water level change (Δa = a-a') in FIG. 1A than in FIGS. 8A and 8B, thereby increasing the ice formation temperature and ice difference in the ice making drum. Can be. Therefore, it is advantageous that the length of the drain pipe portion 30 of the raw material water supply structure of the drum ice maker with easy management of the present invention and improved hygiene is as long as shown in FIGS. 8A and 8B (the amount of storage in the drain pipe portion is minimal. It must be, provided that it serves only as an aisle). That is, the drain pipe portion 30 can form a space 303 for a predetermined narrow-negotiating light whose diameter becomes narrower as the upper and lower ends go downward as shown in FIG. 6A, and the upper and lower opening diameters as shown in FIG. 6B. The same cylindrical shape can be achieved. Drain pipe portion 30 of the present invention is preferably formed to the maximum length between the ice tray in the second slip insertion portion 23 of the on-off valve (20).
