Abstract

PURPOSE:To achieve a quiet cooling with a compact cooler by sending a cooling water to be discharged from a heat exchanger to a water flow stirrer provided at a lower part of a tank to turn a rotary blade of the water flow stirrer. CONSTITUTION:A water flow stirrer 14 is made up of a rotary blade 14 and a magnet 16. The magnet 16 disposed on the top surface of the rotary blade 15 turns with the rotation of the rotary blade 15. A magnet 13 for agitation interlocks the magnet 16 of the rotary blade 15 to make a stirrer rotating within a tank 10. At a cooling water tank 10, a temperature of a drink water is detected with a temperature sensor 17 and when the water temperature rises, a Peltier element 12 is energized and controlled so that water passes through a heat exchanger 11 for cooling and the water flow stirrer 14. When the cooling water tank 10 is cooled by a cold heat of the Peltier element 12, a cooling water is supplied from below the heat exchanger 11 for cooling and after a heat exchange to cool the Peltier element 12, the water is discharged from the top of the heat exchanger 11 for cooling. Then, it is sent to the water flow stirrer 14 and drained at a drain port afterward.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drinking water cooler. [Prior Art] Conventionally, heat pumps have been mainly used for cooling water coolers, and Peltier None of them used elements.

Water coolers that use heat pumps have problems in that they are large and the pumps are noisy.

Therefore, as a method that can reduce the size of the device, and has the possibility of quietly cooling the device, there is a method that uses an electronic cooling element that applies the Peltier effect, a so-called Peltier element. However, this method has the disadvantage that it cannot process a large amount of heat due to poor cooling efficiency.

[Problem to be solved by the invention]

The present invention was proposed to solve the above-mentioned drawbacks, and aims to improve cooling efficiency and process a large amount of heat in order to provide a compact and quiet water cooler. do.

[Means to solve the problem]

The gist of the present invention is to arrange a Peltier element between a tank and a heat exchanger, and to send cooling water discharged from the heat exchanger to a water stirrer provided at the bottom of the tank.
By rotating the rotary blades of the water stirrer,
The water cooler is characterized in that an agitator inside the tank is configured to rotate in conjunction with the rotary blade.

[For production]

With the above configuration, the present invention can improve cooling efficiency by cooling the Peltier element and stirring the tank at the same time, making the cooler compact and allowing quiet cooling. can.

〔Example〕

Next, examples of the present invention will be described. It should be noted that the embodiments are merely illustrative, and it goes without saying that various changes and improvements can be made without departing from the spirit of the present invention.

1 and 2 show one embodiment of the cooler of the present invention.

In the figure, 1 is a base, 2 is a body, 3 is a rear cover, 4 is a switch, 5 is a power cord, 6 is an inlet, 7 is an outlet, and 8 is an outlet.

Inside the body 2, a replaceable purification cartridge 9, a cold water tank 10, and a control section 18 are housed.

A cooling heat exchanger 11 is installed on the side wall of the cold water tank 10.
A Peltier element 12 is disposed between a cold water tank 10 and a cooling heat exchanger 11, with the Peltier element 12 being sandwiched between the cold water tank 10 and a cooling heat exchanger 11.

Inside the cold water tank 10, there is a stirring magnet 13 at the bottom.
A water stream star 14 is installed at the bottom of the cold water tank 10, which has a temperature sensor 17 installed at the top.

The water stream star 14 is composed of a rotary blade 15 and a magnet 16. The magnet 16 arranged on the upper surface of the rotor blade 15 rotates as the rotor blade 15 rotates.

The stirring magnet 13 serves as a stirrer that rotates within the tank 10 in conjunction with the magnet 16 of the rotary blade 15.

Next, the operation will be explained.

Drinking water is taken into the water cooler from the inlet 6, and is first sent from the lower inlet to a water purification cartridge 9 filled with activated carbon or the like, where it is purified.

Thereafter, the purified drinking water is sent from the upper outlet of the water purification cartridge 9 to the upper inlet of the cold water tank 10.

Drinking water is cooled and stored in the cold water tank 10 by the cold heat of the Peltier element 12.

When drinking, cold water is supplied from the outlet 8 by pressing the switch 4.

In the cold water tank 10, the temperature of the drinking water is detected by a temperature sensor 17, and when the water temperature becomes high, the Peltier element 12 is energized so that the water is passed through the cooling heat exchanger 11 and water stirrer 14. It is controlled by H.

When cooling the cold water tank 10 with the cold heat of the Peltier element 12, the cooling water is supplied from below the cooling heat exchanger 11,
After being heat exchanged to cool the Peltier element 12, it is discharged from above the cooling heat exchanger 11, then sent to the water stirrer 14, and then drained from the discharge lower.

At this time, the stirring magnet 13 rotates as the rotary blade 15 inside the water stirrer 14 rotates, so the drinking water in the cold water tank 10 is stirred uniformly and efficiently.
It is cooled by the Peltier element 12.

〔Effect of the invention〕

As described above, the present invention provides a water cooler having a structure in which a Peltier element is sandwiched between a tank and a heat exchanger, in which cooling water discharged from the heat exchanger is sent to a water stirrer provided at the bottom of the tank. By rotating the rotary blades of the water stirrer, the agitator inside the tank, which is linked to the rotary blades, rotates and stirs the water, thereby cooling the Peltier element and stirring the tank at the same time. Since the cooling efficiency can be increased by cooling the water cooler, the water cooler can be made compact and has the effect of being able to perform cooling quietly.
