Description

[Detailed description of the invention] This invention relates to a wastewater treatment structure for an ice maker, and in particular, the overflow water from the water tank installed in the casing of the ice maker is drained from the drain port along with the drain water that collects on the bottom of the lower water storage tank. Regarding what you choose to do.

Conventionally, as shown in FIG. 5, the wastewater treatment structure of such an ice maker has been provided with a water collection port C that communicates with the drain port B on the inner bottom surface of the water storage chamber a, and with the bottom surface facing the water collection port C. The upper end of the hose d, which is tilted downward and has a notch d□ at the lower end, is connected to the drain port f of the overflow pipe g of the water tank e arranged in the upper part of the water storage tank a, and the lower end is connected to the water collection port. By inserting it into the hose C, drain water generated by melting of ice in the water storage tank a is drained into the notch d□ of the hose d.
It is known that the overflow water from the water tank e is led through the water tank e to the water collection port C through the overflow pipe g and the hose d, and is drained together with the drain water from the drain port b. .

However, in the conventional ice maker, the drain port b is provided on the back side of the lower part of the casing in order to facilitate piping connection with the drain passage outside the ice maker, and accordingly, the drain port b and the water collection port C are connected to each other. In order to shorten the length of the connecting pipe, the water collection port C is also provided at the bottom of the ice storage a.

In addition, the overflow drain f of the water tank e is also provided oppositely above the water collection port C so as not to prevent ice from falling into the water storage tank a and to minimize the length of the hose d. It is being

Therefore, when removing the water tank C to the outside of the storage for cleaning, etc., the hose d is located at the back of the water storage storage a, so there is a drawback that the workability of attaching and removing the hose d is poor.

Therefore, in order to improve the workability of attaching and detaching the hose during cleaning, etc., conventionally, the overflow drain of the water tank was provided on the front side of the water storage tank, and a hose receptacle exclusively for overflow water was placed opposite to the bottom of the overflow drain. It has been proposed that a port is provided separately from the water collection port and connected with a hose, and the hose port and the drain port are connected via piping to drain overflow water, but the structure is complicated and In addition to increasing costs, if the hose connection to the hose socket is not complete, overflow water may flow down the bottom of the reservoir to the water collection port and melt the ice in the reservoir.

The present invention has been made in view of these points, and is a drain that collects drain water accumulated at the bottom of the water storage tank and overflow water from the water tank using a heat insulating material placed under the bottom of the water storage storage. In addition, by providing a drain port in the drain pan, a simple structure that utilizes existing insulation material can be used to minimize the hose length and eliminate the need for piping connections. The position can be set to the front side of the water storage regardless of the position of the drain port, making it easier to attach and detach the hose when cleaning the water tank, and ensuring that drain water and overflow water can be drained reliably. The purpose is to

In order to achieve this objective, the structure of the present invention is such that the overflow water from the water tank installed at the bottom of the casing is drained from the drain port along with the drain water that collects at the bottom of the water storage tank at the bottom. In the treatment structure, an opening is provided in the center of the water storage, and a drain groove located corresponding to the opening and a drain port communicating with the drain groove are provided in the heat insulating material disposed below the water storage. On the other hand, a hose socket is provided on the bottom of the water storage container opposite to the overflow drain port of the ice tank, and the overflow drain port and the hose socket are connected with a hose, and the hose of the heat insulating material is also provided. By providing a drainage groove that communicates with the drain port in the area corresponding to the socket, drain water can flow from the opening on the bottom of the reservoir through the drain groove of the drain pan to the drain port, and overflow water can flow from the overflow of the water tank. The overflow drain port and its socket can be positioned on the front side of the water storage tank while shortening the length of the hose by passing water from the drain port through the hose, passing through the drain groove of the drain pan, and then to the drain port.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 to 4 show a waste water treatment structure of an ice maker according to the present invention, in which 1 is a resin bottle with an open front that forms an ice storage in a casing, and the pin 1 is located at the center of the bottom surface. is provided with an opening 2, and the bottom surface is formed to be inclined downward toward the opening 2. On the other hand, at the back of the bottom surface, on the left side, there is a purl-shaped hose receptacle with a peripheral edge hanging downward. A port 3 is provided, into which the other end of a hose 4 is inserted, one end of which is connected to an overflow drain port (not shown) of a water tank disposed at the top inside the bottle 1. .

Reference numeral 5 denotes a drain pan made of a heat insulating material disposed below the bottom of the bottle 1, and the pin 1 opening 2 on the top of the drain pan 5
A drain groove 6 having a U-shaped cross section is provided at a portion corresponding to the drain groove 6, and a column portion surrounded by the drain groove 6 is coated with resin and slopes downward toward the drain groove 6. 7 is formed.

As shown in FIG. 3, the bottom wall of the drain groove 6 is formed to be inclined toward a merging portion 8 provided on the left side of the front portion of the drain pan 5, and as shown in FIG. A drain port 10 of a drain pipe 9 penetrating toward the back is opened in the back wall.

Further, above the left wall of the confluence section 7 of the drain pan 5, there is provided a drainage groove 11 with a U-shaped cross section that descends stepwise from a portion corresponding to the hose socket 3 of the bin 1 to the confluence section 8. and communicates with the drain port 10.

Next, the operation of the above embodiment will be explained.

Drain water generated by melting of the ice stored in the bottle 1 is guided to the drain groove 6 by the slope of the bottom surface of the bottle 1 and the slope of the pillar part 7 surrounded by the drain groove 6.
The water is drained from the drain port 10 to the outside of the casing via the confluence section 8.

On the other hand, overflow water from the overflow drain port (not shown) of the ice tank disposed at the upper part of the bin 1 flows down inside the hose 4 and flows into the drain groove 11 of the drain pan 5 from the hose socket 3. The drain water flows down from the drain groove 11 to the confluence part 8 and is reliably drained to the outside of the casing from the drain port 10 together with the drain water.

Here, the hose socket 3 is provided to correspond to the drain groove 11, and the hose socket 3 is provided with respect to the drain pan 5.
can be freely changed in the front-back direction, so it is possible to position the overflow drain port of the water tank and the hose socket 3 on the front side of the water storage regardless of the position of the drain port 10.

Therefore, the hose 4 can be easily attached and detached when cleaning the water tank.

In addition, the drain pan 5 is configured using existing heat insulating material, and the structure is simple because the conventional connection piping between the water collection port and the drain port and the connection piping between the hose socket and the drain port are not required. Become something.

Furthermore, since the length of the hose between the overflow drain port and the hose socket 3 is short, there is no obstruction to ice falling into the water storage.

In the above embodiment, the lower end of the hose 4 is directly connected to the drainage groove 1.
1, but a part of the hose 4 contacts the upper end of the wall at the upstream end of the drainage groove 11. Therefore, even if a hose 4 whose lower end is cut horizontally is used, the lower end will not contact the drainage groove 11 over the entire circumference. Never get blocked.

As explained above, according to the present invention, an opening for drainage of drain water and a hose socket for draining overflow water are separately provided on the bottom of the water storage, and a heat insulating material is provided on the lower side of the bottom of the water storage. By configuring a drain pan that has a drain groove located corresponding to the opening, a drain groove located corresponding to the hose socket, and a drain port communicating with both grooves, a simple structure can be achieved by using existing insulation materials. As a result, while ensuring reliable drainage treatment of drain water and overflow water, the overflow drain port and hose socket of the water tank can be set on the front side of the water storage regardless of the drain port, making it possible to improve the drainage treatment structure. This has the effect of simplifying the process and improving the ease of attaching and detaching the hose when cleaning the water tank.
