Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier that filters tap water in each household to remove color and odor.

2. Description of the Related Art Recently, household water purifiers have been developed to remove the smell of tap water and drink delicious water.

 Hereinafter, a conventional water purifier with a cooling function will be described.

FIG. 2 is a schematic configuration diagram of a conventional water purifier. 1 is a main body case of a filter, 2 is a heat insulating material, 3 is a thermo module which is a kind of a cooler for cooling tap water to a predetermined temperature, 4 is a radiating plate attached for heat radiation of the thermo module, 5 is A filtration cartridge, 6 is a water supply pipe, and 7 is a discharge pipe. Here, the thermo module is a kind of heat pump that plays a role of transferring heat from a cooling surface to a heat radiating surface by supplied power by a Peltier effect of a semiconductor.

The operation of the conventional water purifier with a cooling function configured as described above will be described below. The filtered water is stored in the body case 1, and when the water is not passed through the water purifier, the water inside the body case 1 is cooled by a thermo module,
When water is passed through the water purifier, cooling water is supplied from the lower part of the main body case 1 through the discharge pipe 7.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, since the water filtered by the cartridge 5 is cooled, there is a problem that bacteria enter the water storage tank from the discharge pipe 7 and propagate therein. Was.

Means for Solving the Problems The present invention uses a water purifier incorporating a cooling means in a main body case, a storage tank for storing raw water, a water supply pipe communicated with an upper part of the storage tank, and an outside of the storage tank. A cooling unit having a heat sink therein and a cooling surface therein, a filter cartridge having a water supply port provided below and a discharge port provided above in the storage tank, and a discharge port of the filter cartridge. With the configuration having a discharge pipe which is provided, water before filtration is cooled.

Operation With the above configuration, cold water can be supplied immediately,
It is possible to obtain a water purifier having a cooling function with low cost and low generation of bacteria.

Embodiment FIG. 1 is a schematic configuration diagram of a water purifier with a cooling function in one embodiment of the present invention. 1 is a main body case, 2 is a heat insulating material,
Reference numeral 3 denotes a thermo module, 4 denotes a heat radiating plate, and 5 denotes a filtration cartridge. These are the same as those in the conventional example. Reference numeral 51 denotes a holding portion that supports the cartridge 5, 61 denotes a water supply pipe opened at the top of the main body case 1, and 71 denotes a discharge pipe fixed to the outflow side of the cartridge 5.

Regarding the water purifier of the present embodiment configured as described above,
The operation will be described below. Water that has entered the upper part of the main body case 1 from the water supply pipe 61 is stored around the filtration cartridge 5, enters the cartridge 5 from a water supply port below the filtration cartridge 5, is filtered by the cartridge 5, and is filtered by the cartridge 5. Supplied by The cooling at this time is performed by the thermo module 3 attached to a predetermined portion of the main body case 1.
And the whole body case 1 is made of heat insulating material 2
This prevents the temperature of the cooled water from rising due to external heat. During the passage of water, the cooled water inside the main body case 1 is pushed by the water supplied to the upper part of the main body case 1, enters the cartridge 5 from a water supply port at the lower part of the filtration cartridge 5, is filtered, and is supplied from the discharge pipe 71. . With such a configuration, the water before being filtered is cooled and stored, so that propagation of bacteria can be prevented. Further, since the entire inside of the main body case 1 is cooled, the water inside the cartridge 5 is also cooled. Therefore, the amount of uncooled water discharged from the discharge pipe 71 at the beginning of use is only the amount of water inside the discharge pipe. The amount of water that becomes ineffective after use is also small. As a result, the amount of water stored in the main body case 1 can be reduced, so that the entire outer shape can be reduced, and the thermo module 3 having a small heat absorption can be used, and the energy consumption can be reduced. The thermo module 3 is the main body case 1
The part that is always in contact with the water passed through the surrounding wall,
Preferably, it is located on the bottom side. Further, since the water supply to the main body case 1 is performed from the upper part of the main body case 1, the water inside the main body case 1 does not convect, so that substantially all of the cooled water inside the main body case 1 can be supplied at a time. .

Advantageous Effects of the Invention The present invention cools raw water before filtration, so that it is possible to supply cold water immediately after passing the water with less generation of bacteria, and to supply a compact and sufficient amount of cold water. You can do it.
