Description

Modular type water purifier

The present invention relates to a modular water purifier, and more particularly, to a modular water purifier in which the functions of water purifier, cold water, and hot water are modularized so that the module can be conveniently installed and used when necessary.

In general, a water purifier is a device for supplying water after removing impurities by filtering water supplied from a water source by physical and chemical methods.

These water purifiers may be classified into natural filtration, direct filtration, ion exchange resin, distillation, reverse osmosis, and the like according to the principle or method of water purification.

In addition, according to the shape of the water purifier, the purified water passing through the filter is stored in the water storage tank and then heated or cooled to drain water, and the purified water purified by passing through the filter without the storage tank is heated or cooled to discharge water. There is a direct water purifier.

Since the direct water purifier does not store a relatively large amount of purified water compared to the storage type water purifier, it is possible to reduce the weight and size, and there are advantages in that the stored water is less likely to be contaminated.

In addition, it is possible to reduce power consumption for storing a large amount of cold water or hot water by maintaining the required temperature.

However, conventionally, a water purifier equipped with only the minimum water purifying function as a low-cost model, a water purifier equipped with only a water purifying function and a cold water function as a mid-priced model, or a water purifier equipped with both water purification, cold water and hot water functions as a high-priced model, respectively. Since it is manufactured and marketed, for example, when a user of a water purifier with only a water purifying function wants to drink cold or hot water, it is inconvenient to receive purified water and cool or heat it separately to drink it as cold or hot water. there was ham

Accordingly, when a separate function such as cold or hot water is desired, the corresponding function cannot be added to the existing water purifier, and thus a new water purifier having the corresponding function must be purchased.
