That is, the water purifier 200 having the reservoir 200 of the inlet 12 of the water tank 10 and the storage container 300 are combined.

An inlet of the upper reservoir 200 of the water purifier unit 1 is provided with a filtration filter 201 for primary filtering the iron or other contaminants of the injected water.

In addition, a water filtration filter 301 for secondary filtration is installed outside the bottom surface of the water storage tank 200 for purifying the coarse water through the filtration filter 201.

At the inlet of the storage container 300 where the outlet of the reservoir 200 is located, a first mineral raw material 302 is installed in parallel with the filter function so that the water of the reservoir 200 gradually moves to the storage container 300. The bottom surface thereof is provided with a second mineral generating filter 303 for continuously replenishing minerals with purified water.

At this time, the first mineral generating filter 302 and the second mineral generating filter 303 are filled with coral sand with bacteriostatic function while containing high quality minerals.

Also, as shown in FIG. 2B, the bottled water bottle 400 storing the bottled water may be seated at the upper inlet 12 of the water tank 1.

A pulse width modulator 105 for controlling the control unit, a thermal protection control output unit 107 for generating a predetermined output signal for protecting the cooling member 30 from heat; The output voltage of the output rectifier 103 is interrupted by the signal output from the thermal protection control output unit 107 to generate an output signal for controlling the temperature of the cooling water, accelerating the adjustment time, and controlling the driving of the exhaust fan 60. It is characterized by consisting of a portion (106).

The water tank 10 is a container body for storing water. An inlet 12 is opened at an upper portion thereof, and a valve 11 is installed at one side of the bottom surface to control the supply of water.

At this time, the water to be used is, for example, when the water purifier unit 1 is installed in the upper portion of the water tank 10 as shown in the installation state of FIG. 2, the water purified by the water purifier unit 1 After entering the inlet 12 of the water tank 10 through the outlet (2) to be soaked, it is to be cooled to a predetermined temperature using the thermoelectric element to be ingested.

And, in the case of FIG. 2, the water purified through the water purifier or various beverages including the purchased bottled water is contained in the water tank 10, and the upper part is covered with the cover 22 to cool the water and then ingested. The state of the unit chiller is shown.

The casing 20 is a casing for enclosing the exterior of the water tank 10, the cooling member 30, and various apparatuses including the thermoelectric element 40, etc., and the exterior is beautifully decorated and painted. It is molded from ABS resin with good heat resistance, impact resistance and stiffness, or synthetic resin material with similar properties.

In this case, since the filtration filter 201 and the water purification filter 301 for primary filtration are installed at the injection port of the upper reservoir 200 as shown in FIG. 2, the water transferred through the tubular body is filtered by the filters 201 and 301. Eliminate impurities that are harmful to the human body.

In addition, the water is transferred to the storage vessel 300 having a predetermined size through the outlet of the upper reservoir 200 by its own weight, wherein the inlet of the storage vessel 300 serves as a filter. Since the first mineral generating medium 302 is provided in parallel, the water in the reservoir 200 gradually receives the rich mineral while passing through the first mineral generating medium 302.

Water transferred to such a storage container 300 is a greater amount through the second mineral generating media 303 installed on the bottom thereof, that is, a large amount of mineral is deposited on the bottom of the storage container 300] Since the mineral is supplemented, the user can consume high quality mineral water, that is, weakly alkaline water.

And, between the water tank and the case 20 is filled with a heat insulating member 21 for heat insulation to maintain the cold temperature.

The cooling member 30 is a metal member that is located inside the water tank 10 to take heat away from the thermoelectric element 40, and ice is formed around the cooling member 30 to form an ice maker. This ice rod cools water filled around it by cooling below freezing point.

At this time, by the control means 100 to be described later so as not to freeze all the parts of the water tank 10 by continuously freezing around the cooling member 30 to obtain the cooling member 30 to maintain only a low temperature state with water suitable for drinking The control means 100 is controlled.

The cooling member 30 is molded so as to have a hollow cross section as a means for increasing the surface area of the harmless metal component, especially made of aluminum, which is free of corrosion and is not concerned with corrosion.

As shown in the drawing, the cooling member 30 is fixed to the bottom surface of the water tank 10 by screwing the holder 31 supporting the cooling member 30 with the nut 32.

The thermoelectric element 40 -Thermo Electeic Module- takes heat from one side and heat from the other side when driving current to flow to a device having a conductive material bonded using a Peltier Effect. The structure and principle of operation of the thermoelectric element 40 are as already known.

Therefore, the cooling member 30 is positioned at the position where heat is to be taken to cool the water contained in the water tank 10 at a low temperature, and the heat sink 50 is installed at the position where the heat is moved.

An electrical insulator is installed between the cooling member 30 and the heat sink 50 installed at both sides of the thermoelectric element 40 to prevent a short circuit or an electrical hazard. It is good to select and install the one with excellent heat conduction.

The heat sink 50 releases the moved heat to the atmosphere, and the temperature sensor 51 may be installed at one side.

The temperature sensor 51 detects the temperature of the heat sink 50 and controls the operating state of the thermoelectric element 40. The heat generating temperature of the heat sink 50 and the cooling temperature of the cooling member 30 are proportional to each other. Therefore, it is good to install the 'on' and 'off' switch 71 and the 'strong' and 'weak' switch 72 so as to sense the heating temperature so as to cut off the power so that the user can select a desired capability state. .

In addition, it is preferable to install an exhaust fan 60 on the bottom of the heat sink 50 in order to forcibly expel heat generated quickly and to the outside.

At this time, a plurality of discharge holes 23 are drilled on the bottom surface of the case 20.

In addition, the inside of the water tank 10 is installed to cover the ceramic cover 14 with holes 15 at a distance from the cooling member 30 as a means for preventing the discharge of cold air to the outside. It is preferable at the point of view.

On the other hand, the operation of the control means 100 shown in FIG. 3 is as follows.

First, the input rectifier 101 rectifies a commercial voltage having a frequency of 50-60 Hz to a pulse current through a full-wave rectifier composed of diodes, and then filters a ripple voltage through a capacitor to apply a stable DC voltage to each part.

In this way, when the DC voltage rectified through the input rectifying unit 101 is applied to the field effect transistor in the high frequency inverter 102, the field effect transistor performs on / off operation at a high speed, and thus the primary of the transformer connected to the drain thereof. A high voltage pulse of about 130 KHz is applied to the coil to induce a voltage of a predetermined frequency on the secondary side of the transformer.

The pulse voltage of a predetermined frequency output from the high frequency inverter 102 is rectified and smoothed to a constant voltage through the output rectifier 103 and applied to the control circuit unit 104 and the output signal generator 106 as a stable voltage.

When the predetermined voltage is output from the output rectifier 103, the comparator in the control circuit section 104 compares the output voltage with a predetermined reference voltage and feeds the resultant back to the input of the optical coupler, thereby providing the optical coupler. Is driven to apply a predetermined output signal to the error amplifier of the pulse width modulator 105.

Therefore, in the pulse width modulator 105, the output signal of the error amplifier which amplifies the output signal of the control circuit unit 104 and the oscillation signal in itself are copied, and the frequency and pulse width of the output pulse are determined by the signal.

That is, when a pulse signal having a predetermined frequency and a pulse width is output from the pulse width modulator 105, the field effect transistor in the high frequency inverter 102 is turned on / off by this signal, so that AC voltage is induced.

On the other hand, in the output signal generator 106 receiving the output voltage of the output rectifier 103, the output voltage of the output rectifier 103 is controlled by the output signal of the thermal protection control output unit 107 to adjust the temperature of the coolant. And controlling the driving of the exhaust fan 60 according to the acceleration of the adjustment time.

In this case, since the output signal generator 106 includes a temperature sensor 51 installed in the heat sink 50, the driving of the exhaust fan 60 may be controlled by the detection amount of the temperature sensor 51.

That is, the field effect transistor is driven because a 'high' signal is generated when the temperature of the heat sink 50 exceeds the proper temperature by comparing the output voltage of the temperature sensor 51 with a predetermined reference voltage through a predetermined comparator. Since the output voltage of the output rectifier 103 is applied to the exhaust fan 60, the exhaust fan is driven to lower the temperature of the heat sink 50 again.

In addition, the heat protection control output unit 107 is the temperature of the heat sink 50 and the power supply unit located on the back of the cooling member 30 in order to increase the cooling rate (ie, time) of the cooling water is the temperature The rotation speed of the exhaust fan 60 may be controlled by detecting the sensor 51 and controlling the transistors of the output signal generator 106.

In other words, since the rotation speed of the exhaust fan 60 is controlled by receiving the predetermined signal output from the thermal protection control output unit 107 from the output signal generator 106, the cooling member by the forced blowing of the exhaust pins. When the temperature of the cooling device 30 is lowered or the temperature of the cooling member 30 is low due to the low ambient temperature, the driving of the exhaust fins may be blocked to prevent unnecessary power loss in advance.

The above-mentioned configuration is not necessarily limited to this, the liquid drink water other than water can be used for any purpose that can be ingested immediately cool by cooling anything.

The present invention as described above, First, there is no noise at all in the room so that you can take a cool drink in a comfortable indoor environment.

Second, since it is light and easy to move, it can be widely used by installing in a desired place such as a general home or a restaurant.

Third, the price is low and the electricity consumption is extremely low, thereby reducing the economic burden.

Fourth, it is a very useful design that can be directly connected to the water filtered by the water purifier, or to be filled in the water tank of any kind, such as bottled water and tap water, and then cooled to cool.
