Pipe Connecting Cap for Ice Making Water Purifier

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe connecting cap, and more particularly, to a pipe connecting cap for an ice making water purifier capable of easily connecting a refrigerant pipe and a hot gas pipe to a main pipe of an evaporator.

A general cold / hot water purifier is a device that purifies raw water such as tap water to supply to a user, or supplies cold water and hot water to a user by cooling or heating purified water.

In recent years, ice-making water purifiers have been sold which have an ice-making function capable of generating ice in a cold / warm water purifier.

1, an immersion pipe 42 protruding from a main pipe 41 of an evaporator 40 is immersed in ice water to freeze water to form ice. The refrigerant pipe P1 is connected to the main pipe 41 of the evaporator 40 and the low temperature refrigerant flows to the immersion pipe 42 through the refrigerant pipe P1 to freeze the water.

After the ice is generated, the refrigerant (hot gas, hot gas) of high temperature and high pressure generated in the compressor 10 is guided to the immersion pipe 42 for easy separation of the ice and the immersion pipe 42 The hot gas pipe P 2 is connected to the main pipe 41 of the evaporator 40.

The refrigerant pipe P1 and the hot gas pipe P2 must be connected to the main pipe 41 of the evaporator 40. As shown in FIG. 2, conventionally, the inside of the main pipe 41 of the evaporator 40 The refrigerant pipe P1 and the hot gas pipe P2 were inserted into the pipe and welded with a welding rod to fix the three pipes (the main pipe, the refrigerant pipe, and the hot gas pipe). In order to prevent leakage of refrigerant or hot gas, a space between the pipes was filled with a welding rod.

However, since this method is difficult to obtain, it is difficult to obtain high quality welding quality, and a large amount of welding electrodes are used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a pipe connection cap for an ice maker according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a perspective view showing a pipe connecting cap for an ice maker according to the present invention, and FIGS. 4a and 4b are views showing a pipe connecting cap for an ice maker according to the present invention connected to a main pipe of an evaporator.

The pipe connecting cap for ice making water purifier according to the present invention is used for connecting the refrigerant pipe P1 and the hot gas pipe P2 of the ice making water purifier to the main pipe 41 of the evaporator 40. [

Prior to description of the present invention having such an application, the construction of the ice-making purifier will be briefly described first with reference to Fig.

The ice-making water purifier circulates the refrigerant sequentially through the compressor 10, the condenser 20, the capillary tube 30, and the evaporator 40 to cool or warm water or make ice.

The evaporator 40 can be divided into a main pipe 41 and an immersion pipe 42. The main pipe 41 is connected to a refrigerant pipe P1 through which refrigerant flows, (P2) are connected.

The immersion pipe (42) is immersed in water stored in the water receiving member (50) to transfer cold air of cold refrigerant, thereby generating ice by deicing the water.

On the other hand, when the immersion pipe 42 is immersed in water to make the surrounding water ice, the outer surface of the immersion pipe 42 and the ice are firmly attached to each other. The immersion pipe 42 in this state is easily separated There is a need for a separate means.

As a means for separating the immersion pipe 42 from the ice, a hot gas pipe P2 through which a refrigerant (hot gas) compressed at a high temperature and a high pressure flows in the compressor 10 flows into the main pipe 41 so that the hot gas can provide heat to the immersion pipe 42. When the heat of the hot gas is transferred to the immersion pipe 42, the attachment surface of the ice adhering to the immersion pipe 42 is finely melted and the immersion pipe 42 is easily separated from the ice.

The refrigerant pipe P1 is connected to the main pipe 41 of the evaporator 40 and the hot gas pipe P2 is provided for easy separation of the ice and the immersion pipe 42 from the evaporator 40, ) To the main pipe (41) of the evaporator (40).

That is, two pipes (a refrigerant pipe and a hot gas pipe) are connected to one main pipe 41. The connection cap 100 according to the present invention is used to facilitate such connection operation.

The connection cap 100 according to the present invention is formed in a cylindrical shape whose overall shape is the same as or substantially the same as the inner diameter of the main pipe 41 of the evaporator 40.

The connection cap 100 is formed with a first insertion hole 100a and a second insertion hole 100b.

The first insertion hole 100a is where the refrigerant pipe P1 through which the refrigerant is guided is inserted and welded.

The second insertion hole 100b has a relatively larger diameter than the first insertion hole 100a and a hot gas pipe P2 through which the refrigerant compressed at a high temperature and a high pressure by the compressor 10 is guided Is inserted and welded.

Thus, the refrigerant pipe P1 and the hot gas pipe P2 are firmly fixed to the connection cap 100. The main pipe 41 of the evaporator 40 and the refrigerant pipe P1 and the hot gas pipe P2 are connected to each other by inserting the connection cap 100 in this state into the inlet of the main pipe 41 of the evaporator 40, Respectively. At this time, when the connection cap 100 is inserted into the main pipe 41 of the evaporator 40, the connection cap 100 is tightly and tightly inserted into the main pipe 41.

That is, the connection cap 100 is inserted into the inlet of the main pipe 41 of the evaporator 40 while the refrigerant pipe P1 and the hot gas pipe P2 are connected to each other. At this time, And is in close contact with the inner peripheral surface of the main pipe 41. Therefore, no refrigerant or hot gas flows between the connection cap 100 and the main pipe P1.

Meanwhile, the connection cap 100 may be fixed by welding to the inlet of the main pipe 41, or may be forcedly press-fitted into the inlet of the main pipe 41.

The diameter of the main pipe 41 of the evaporator 40 is not equal to the entire length of the evaporator 40, and the diameter of the main pipe 41 is reduced from a certain distance from the inlet. When the diameter becomes smaller, a step 41a is formed at the point. The step 41a serves as a stopper for preventing the connection cap 100 from coming in.

That is, since the diameter of the main pipe 41 of the evaporator 40 to which the connecting cap 100 according to the present invention is applied is reduced from a certain distance from the inlet, the step 41a, which serves as a stopper, The connection cap 100 is prevented from entering the main pipe 41 any longer.
