Abstract

PURPOSE: A device for mixing cold and warm water for a washing machine is provided to improve productivity, to save costs and to avoid the decrease of consumer's preference on a product. CONSTITUTION: Cold and warm water flows in through a cold/warm water passage of a joining port(4) and mixes with warm water of a proper temperature in a joining passage. The mixed cold and warm water is supplied to a washing machine through a mixed water feed pipe(6). The washing machine requires only each one water feed valve and a mixed water feed pipe(6) to receive the warm and cold water simultaneously. Thereby, the processes of producing and assembling and the number of components are minimized. Additionally, the waste of fuel is avoided by shutting-off a warm water feed source and opening only a cold water feed source in summer.

Description

Cold and hot water mixing device for washing machine {DEVICE FOR MIXING COLD AND HOT WATER IN WASHING WACHINE}

The present invention enables the supply of cold and hot water mixing equipment for washing machines, and more specifically, cold and hot water supplied for washing into a washing tank by a single water supply hose, thereby minimizing manufacturing labor and required parts, and It is for convenience.

In a general washing machine, washing is performed by mixing cold water or cold and hot water according to the type of laundry, the degree of contamination or the user's needs. Accordingly, a cold and hot water valve is installed at the rear of the main body of the washing machine. It is well known that a cold and hot water hose is connected between a water supply valve and a cold and hot water source.

By the way, the problem in the conventional washing machine, first, each of the cold and hot water supply valves for introducing cold and hot water to the back of the washing machine main body should be installed, so as to increase the number of manufacturing and assembly labor as well as the required parts productivity This is caused by lowering costs and rising costs.

In addition, since cold and hot water hoses are separately supplied to consumers, it is very difficult to store and install them, which hinders consumer's preference for products, and it is pointed out that the cost increase factor is increased because two water hoses must be supplied.

The present invention has the object to provide a cold, hot mixed water supply device for a washing machine that can actively solve the above problems, the present invention cold, hot mixed water supply device for achieving the above object effectively, cold, hot water supply Cold and hot water introduction pipes each introducing cold and hot water from a water source, a mixing water supply pipe for mixing cold and hot water introduced from the cold and hot water introduction pipes, and a mixed water supply pipe for supplying mixed water discharged from the water supply port to the washing machine. It consists of.

Hereinafter, a preferred structural example of the present invention will be described in detail by the accompanying drawings in which the left side is set to cold water and the right side to hot water.

1 is an exploded view of the present invention, the hot and cold hop water supply device (S), having cold and hot water supply (1a, 1b) connected to the connection (2a, 2b) to introduce cold, hot water, Water inlet pipe (3a, 3b), and the inlet portion (41a, 41b) is connected to the cold, hot water inlet pipe (3a, 3b) is formed is a water inlet (4) for mixing the introduced cold and hot water, and It is composed of a mixed water supply pipe 6 for supplying the mixed water discharged to the washing machine shaft having a fastening portion 5 connected to the lower portion of the water inlet (4).

The cold and hot water introduction pipe (3a, 3b) is a flexible material is formed in a suitable length, preferably 30 to 50cm in length in consideration of the gap between the cold and hot water source (1a, 1b), on the top The provided connector (2a, 2b) is composed of a fixed body 21 is fastened and fixed to the cold and hot water supply (1a, 1b), respectively, and a connecting body 22 detachably entered into the bottom of the fixed body 21 The lower end of the connecting body 22 is formed with a downward protrusion of the connecting portion 23 into which the cold and hot water introduction pipes 3a and 3b are press-fitted.

The water inlet 4, which is press-connected at the lower end of the cold and hot water introduction pipes 3a and 3b, the upper end of which is press-fitted to the connection part 23, has the cold and hot water passages 42a and the inside of the press-ining parts 41a and 41b. The cold and hot water introduced through the 42b) is mixed and discharged from the confluence passage 43, and the screw portion 44 is formed on the lower outer surface of the confluence port 4 so that the fastening screw portion of the fastener 5 is retracted. 51) is fastened.

The fastener 5 is formed so that the friction portion 52 is formed on the outer surface to be assembled and disassembled by the grip force without a separate tool, the inside of the packing (7) is inserted to prevent the leakage of mixed water do.

In addition, the lower part of the fastener 5 is provided to prevent the fastening pipe body 53 that can be freely rotated, and the lower part of the fastening pipe body 53, the tightening portion that the upper end of the mixing water supply pipe 6 is press-fitted 54 is further provided.

In the figure, reference numeral 24 denotes a hook for preventing separation.

Figure 2 shows the connection use state of the present invention cold, hot water mixing equipment (5), the user first, the cold, hot water supply pipes (2a, 2b) of the upper end of the cold, hot water introduction pipe (3a, 3b), respectively The fastening is fixed to the circle (1a, 1b), in this case, only the fixing body 21 is fixed to the cold and hot water supply (1a, 1b), if necessary, separate the connecting body 22 from the fixing body 21 By doing so, the cold and hot water introduction pipes 3a and 3b can be separated.

In addition, the user is connected to the washing machine (not shown) provided in the lower end of the mixing water supply pipe 6, when the fastener 5 of the upper end of the mixing water supply pipe 6 is separated from the water inlet 4 The assembly is completed by inserting the packing 7 inside the fastener 5 and fastening the fastening screw part 51 to the screw part 44 of the water inlet 4.

At this time, the cold, hot water supply source (1a, 1b) should be switched to the open state, when operating the washing machine not shown in this state, the water supply valve is opened to wash water from the cold, hot water supply (1a, 1b) Will be supplied.

The cold and hot water supplied through the cold and hot water introduction pipes 3a and 3b are respectively introduced through the cold and hot water passages 42a and 42b of the water inlet 4 to the hot water at an appropriate temperature in the water passage 43. After mixing, it is supplied to the washing machine through the mixing water supply pipe (6).

Therefore, the washing machine requires only one water supply valve and the compatible water supply pipe 6 for simultaneously supplying cold and hot water, thereby minimizing manufacturing and assembly labor and required parts.

On the other hand, the user can prevent the waste of the fuel by closing the hot water supply source 12 in the summer and open the cold water supply source 16 to proceed with the laundry, in the winter, cold, hot water supply (1a, 1b) ) By simultaneously opening the washing by hot water to maximize the washing efficiency.

In addition, when the cold and hot mixed water supply device 5 is kept, its volume is minimized, so it can be stored and stored in a narrow space, and when the mixed water supply pipe 6 is separated in a connected state, it can also be temporarily used as a mixed water supply faucet. have.

For example, when separating the mixing water supply pipe 6 and connecting the shower has the advantage that it can be used for other purposes, such as can be used to control the cold, hot water.

According to the present invention cold and hot mixed water supply device as described above, the configuration and required parts of the washing machine and the water supply device is simple and minimized, it is possible to actively implement a significant improvement in the workability and productivity and cost reduction, convenience of use By improving the user's product preferences, the failure rate is minimized by the simplified configuration, so that the user's product reliability can be improved.
