Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier with a cooling function, and more particularly to a domestic water purifier that filters tap water in each household.

2. Description of the Related Art Hereinafter, an example of a conventional water purifier with a cooling function will be described with reference to the drawings. In FIG. 2, reference numeral 11 denotes a cooling water storage tank;
Is a main body case that houses a filtration cartridge 16 for filtering water, 13 is a heat insulating material covering the outer periphery of the cooling water storage tank 11, and 14 is a thermometer in which a heat absorbing portion is disposed in close contact with the upper side surface of the cooling water storage tank 11. Module, 15 is thermo module
14 radiator plate, 17 is connected to the upper part of the cooling water storage tank, a water supply pipe for supplying water from the water source 17 to the cooling water storage tank 11,
Reference numeral 18 denotes a joint connecting the cooling water storage tank 11 and the cartridge 16, and reference numeral 19 denotes a discharge pipe connected to the upper portion of the cartridge 16 and supplying cooled purified water to the outside. Cooling water storage tank 11
The water inside is cooled to a certain temperature by the thermo module 14. The heat radiating plate 15 is attached for heat radiation of the thermo module 14. The thermo module 14 is a kind of heat pump that serves to transfer heat from a cooling surface to a heat radiating surface by electric power supplied by a Peltier effect of a semiconductor. This cooling method is called thermoelectric cooling or electronic cooling. Water that has entered through the water supply pipe 17 is cooled by the cooling water storage tank 11. here,
It is best to cool the water by the amount of water flow, but the heat absorption thermo module that can cool the water flow is very expensive and cannot be used for general purposes. In addition, a method using a compressor as a cooling method results in a large outer shape, which is also not preferable for general use. Therefore, in order to perform cooling using a low-cost (low heat absorption) thermo module, a tank for storing the cooled water is provided, and the water inside the tank is cooled when not in use. When used, water can be supplied from the lower side of the tank. Cooled water passes through fitting 18 and cartridge 16
to go into. The water filtered by the cartridge 16 is supplied from the discharge pipe 19 for drinking.

Problems to be Solved by the Invention Meanwhile, with the above-described configuration, it is not possible to supply cold water until the water in the cartridge 16 and the joint 18 where no cooling device is provided flows out. In addition, the cold water remaining in the cartridge 16 and the joint 18 is heated by external heat and becomes ineffective if time elapses until the next use. For this reason, in order not to hinder the use of cold water, it is necessary to increase the capacity of the tank and increase the heat absorption of the thermo module. In addition, since the surface area of the tank is thereby increased, it is necessary to increase the thickness of the heat insulating material for keeping cold, which increases the cost, increases the outer shape, and has a problem that cold water does not immediately come out. The present invention solves such a problem, and an object of the present invention is to provide a low-cost water purifier with a cooling function that can use cold water immediately.

Means for Solving the Problems In order to solve the above-mentioned problems, the water purifier with a cooling function of the present invention, the main body case covers the outer periphery with a heat insulating material, the bottom has a concave shape having an inclined surface, and the water supply pipe. A cooling cartridge provided with a water supply port and a discharge pipe inside the main body case so that the water supply port is located in a concave portion at the bottom of the main body case. The water stored inside the main body case is configured to be cooled.

Operation With the configuration described above, the water purifier with the cooling function of the present invention can supply cold water immediately because the water in the cartridge is cooled in advance.

Embodiment Hereinafter, a water purifier with a cooling function according to an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, 2 is a main body case for accommodating a cartridge 6 for filtering water, 3 is a heat insulating material covering the outer periphery of the main body case 2, and 4 is a heat absorbing surface for the main body case 2.
A thermo module, which is disposed in close contact with the upper side surface of the module, 5 is a heat sink of the thermo module 4, 7 is connected to the upper part of the main body case 2, and a water supply pipe for supplying water from the water source into the main body case 2, 9 is connected to the upper part of the cartridge 6. Cartridge 6
This is a discharge pipe that supplies cold water from outside. Water entering the upper part of the main body case 2 from the water supply pipe 7 is stored around the cartridge 6 in the main body case 2, enters the cartridge 6 from a water supply port 6 a at the lower part of the cartridge 6, is filtered by the cartridge 6, and is filtered by the cartridge 6. Supplied by The cooling at this time is performed by attaching the heat absorbing portion of the thermo module 4 to the upper side surface of the main body case 2. Further, the entire body case 2 is covered with a heat insulating material 3 to prevent the temperature of water inside the body case 2 from rising due to external heat. In use, the cooled water inside the main body case 2 is pushed by the water supplied to the upper part of the main body case 2, enters the cartridge 6 from the water supply port 6 a at the lower part of the cartridge 6, is filtered, and is supplied from the discharge pipe 9. . With such a structure, the entire inside of the main body case 2 is cooled, so that the water inside the cartridge 6 is also cooled. For this reason, the amount of uncooled water that appears at the beginning of use is only the amount of water inside the discharge pipe, and 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 2 can be reduced,
The overall shape can be reduced, and a small thermo module can be used, and the cost can be reduced. Further, since water is supplied to the case 2 of the present invention from the upper portion of the main body case 2, the water inside the main body case 2 does not convect, and all the cooled water inside the main body case 2 can be used at a time. Thus, by adopting the structure of the present embodiment, it is possible to obtain a water purifier with a cooling function that can supply cold water immediately and that is compact and inexpensive, and that can supply a sufficient amount of cold water. it can.

Effect of the Invention As is clear from the above description of the embodiment, according to the water purifier with the cooling function of the present invention, by providing the cooling means in the main body case, it is possible to supply cold water immediately and it is compact and inexpensive. Moreover, a water purifier with a cooling function capable of supplying a sufficient amount of cold water can be obtained.
