Abstract

PURPOSE:To make the titled apparatus simple and inexpensive while facilitating the maintenance thereof, by condensing steam in air by a freezing apparatus, and filtering and sterilizing condensed water. CONSTITUTION:Air A is heat exchanged with a cooling medium in a water collecting unit 2 to condense steam in air and condensed water is stored in a water storage tank 11 from a dew receiving tray 10. The cooling medium is recirculated through a compressor 3, a condenser 4 and an evaporator 6. Condensed water is passed through a mineral substance adding device 16, a filter 18 and a sterilization apparatus 20 by a pump 13 and introduced into a tank 28 and cooled. When the filter 18 is clogged, a circuit shown by a broken line part is formed in a three-way valve 52 and the pump 13 is driven while water in the water storage tank is passed through bypass piping 35 and the filter 18 is backwashed to remove the clogging by activated carbon 19.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a drinking water production device that produces drinking water by completely condensing water vapor in the air using a refrigeration device.

[Commercial technology]

Conventionally, the method of collecting water vapor in the air to obtain water is to use a hygroscopic agent such as synthetic zeolite, which adsorbs the moisture in the living air, then heats up and releases the moisture.
The method used was to cool it and condense the water. Although this method allows water to be supplied even when the relative humidity is very low, it has the disadvantage that the process is complicated and the cost of the equipment is high. In addition, te+Ji water is supplied to areas to be flooded through an off-shore filter system, but as it is used for a long time, the water becomes clogged and the filtration capacity decreases, resulting in earlier replacement of the water filter system. .

[Summary of the invention]

This invention was made in view of the above-mentioned circumstances, and it is possible to simply clean the filtration device using a refrigeration device, by borrowing an inexpensive drinking water production device and using the condensed water obtained from the refrigeration device. This is how it was done.

Next, the entire operation will be explained. Initially, the water collection unit tel is 1
It can be rotated. The refrigerant discharged from the compressor (3) is sent to the condenser (
In step 4), it exchanges heat with air B and liquefies it.

Air B is heated and becomes air O, which is sucked into the blower (8) and blown out of the unit. The liquefied refrigerant is depressurized by the expansion device (5), becomes a low-temperature gas-liquid mixture tC, and flows into the evaporator (6), where it converts heat with air A and vaporizes. On the other hand, air A is cooled. and becomes air B as described in B11. The vaporized refrigerant is sucked into the compressed charcoal t31 V, and the above-mentioned cycle is carried out.

In this refrigeration cycle, the storage device (5) is adjusted so that the evaporation temperature is further 10 to 15°C lower than the dew point temperature of 52A. Therefore, a portion of the air A that has entered the evaporator (6) is cooled to below the dew point temperature. Due to O, the water vapor in the air A condenses on the surface of the four generators 16). The condensed water drips onto the tray (10) installed below the evaporation drip (6), and then into the tray #t121.
Inside? The water flows down and is stored in the water storage tank (11). When the pump is operated in the water storage state, the water in the water tank (11) is sucked through the suction pipe (14), and passes through the discharge pipe (16) to the mineral additive (1f9). During the time it enters and passes through this stage, trace amounts of minerals such as tetrium and calcium are added by frozen water stone +17).

It passes through the pipe (to) the filter Qal [the water that enters is filtered with activated carbon (
19), it is filtrated and deodorized.

The water from the filter (1 ladle goes through the pipe ■ to the sterilizer I2

9) and enter I2 in the evening. Inside the tank (c), water is cooled by the action of a refrigeration system consisting of a compressor, a radiator (24), a capillary tube (to), and an evaporator, and is cooled down to 8 to 12 degrees Celsius, which makes it delicious for drinking.
cold water. Therefore, when the cock valve clη is opened, the faucet (
g) Colder water will flow out, so if you collect it with a tap, you can use it for drinking.

By the way, if you use it regularly, the filter α barrel will wear out, the passage resistance will increase, and the water from the faucet (3o) will become difficult to suck. This is caused by clogging of the activated carbon (19) near the water inlet (18-1). Therefore, if this condition occurs, the push button switch (sl f

iIIIll, and the second contact (61-8) is closed. Therefore, a self-holding circuit for relay 1611 is formed, and at the same time, the motor (62-1), coil (G3), and coil β-turn lamp are energized, and at the same time, the coil is turned on. In addition, one streetcar is connected to the motor (6η).As a result, the three-way valve (5) forms the circuit shown by the broken line in the diagram, and the three-way valve (7) is the same as the three-way valve (7), and the three-way valve +
511 is opened, and the pump is driven.

In this case, the water sucked from the water storage tank (11) passes through the mineral cap III vessel θ passage to the three-way valve (6-way bypass pipe). Since the three-way valve (61) is open, the water in the bypass power distribution) flows backward through the filter θ barrel according to the piping diagram, and is discharged from the branch pipe (2). The zero portion of the activated carbon 1191 is washed by this water flowing back. Then, the lamp lights up, fully indicating that cleaning is in progress. When this backflow cleaning is carried out for 8 minutes, the time limit contact (62-2) opens and the cleaning ends automatically. That is, when the time limit contact (62-23 opens),
The coil (61-2) is demagnetized, and both the 1/2 contact (61-2) and the 2nd contact (61-81) return to the illustrated state, and the entire circuit returns to its original state.

[Other examples]

In the above explanation, the cleaning f was started by operating the push button (61), but instead of the push button (6 [I), the slow switch (not shown) k 11
In addition to adding a timer C (not shown) for accumulating the contact closing time of the slow switch C, the timer may be used to automatically turn the cleaning purple.

[9e Ming effect] The effects of this invention are listed below.

(1) As with eaves, the process of absorbing all the water vapor in the air (adsorbing all the water vapor in the air with a moisture absorbent, then heating it up and releasing it, and then cooling the air to condense all the water vapor) is done. Since the nitrogen gas is cooled and the water vapor is completely condensed immediately, the device can be manufactured at a lower cost than the vehicle in front of the vehicle.

(2) Since the entire p-filter can be backwashed using water in the tank, maintenance is easy and the life of the filter can be extended.
