Description

Fresh water generator and water server

The present invention can obtain water using air in the atmosphere as a raw material, and in particular, a fresh water generator that can be easily installed in homes and can stably obtain water suitable for drinking water, etc. About.

Water is indispensable for living organisms, but there are limited areas where stable supply of water (especially suitable for drinking water) is possible. There are many places where it is difficult to obtain water suitable for drinking water, even in dry regions such as deserts, even in regions and countries where water is abundant at first glance. For example, there are areas where the sanitary environment is bad or rivers are polluted, remote islands where water supply is not complete.

Measures for obtaining water suitable for drinking water in such places include regeneration of sewage and the like, and desalination of seawater. However, such treatment requires large equipment and is not easy to introduce. In addition, since water (liquid) as a raw material is necessary in the first place, the area where introduction is possible is limited.

Therefore, it has been proposed to obtain water (liquid) from water vapor present in the atmosphere. For example, there is a description related to the following patent document.

Japanese Patent Publication No.62-21666 Japanese Patent No. 4271705

In both Patent Document 1 and Patent Document 2, heated air is passed through an adsorbent that has adsorbed water vapor in the air, and the resulting wet air is cooled to produce water. Patent Document 1 proposes a fresh water generator in which a flow path of air introduced into an adsorbent and a cooling flow path of wet air derived from the adsorbent are separated. Patent Document 2 proposes a fresh water generator that can operate without power supply by heating air to be introduced into an adsorbent that has adsorbed water vapor or supplying air in each flow path by solar heat. .

The fresh water generator as in Patent Document 1 is large and difficult to spread to ordinary households. In addition, a fresh water generator like Patent Document 2 is not preferable because the amount of water indispensable for daily life is easily affected by climate change.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a fresh water generator and the like that can be made compact and stable in the amount of fresh water and can be easily introduced into the home. .

As a result of diligent research to solve this problem, the present inventor moved the adsorbent, supplied air, and heated with electric power, and devised a cooling structure for the humid air that flowed out of the adsorbent, thereby reducing the size. And newly developed a fresh water generator that can stabilize the amount of fresh water. By developing this result, the present invention described below has been completed.

<Fresh water generator>
(1) The fresh water generating apparatus of the present invention adsorbs water vapor to the removable filter by accommodating the removable filter that allows air to pass through while adsorbing or desorbing water vapor, and housing the removable filter and guiding air to the removable filter. A filter case having a first section to be made and a second section for desorbing water vapor from the detachable filter, and an electric motor for moving the detachable filter continuously or intermittently between the first section and the second section A first flow path that continues from the air intake opening that opens to the atmosphere to the exhaust opening that opens to the atmosphere through the first section; a first electric fan that causes the air in the first flow path to flow; A second flow path returning from the downstream side to the upstream side of the second section, a second electric fan for flowing the working air in the second flow path, and an electric heater for heating the working air flowing into the second section And the second ward Comprising a capacitor to obtain a condensed water is cooled by air passing through the said flow channel a working air flowing out, a water storage tank for water storage the condensed water, from.

(2) According to the fresh water generator of the present invention, first, driving of the detachable filter, intake / exhaust of air as a raw material, and heating and flow of working air are performed using electric power. For this reason, as long as electric power can be supplied from a commercial power source, a storage battery, or the like, the fresh water generator of the present invention continues to operate, and a stable amount of fresh water can be secured.

Next, in the fresh water generator of the present invention, when the condensed air is obtained by cooling the air (referred to as “humid air”) obtained by allowing the heated working air to pass through the removable filter that has adsorbed water vapor, the removable filter is used. Air that is taken in to adsorb water vapor (referred to as “raw air”) is used. As a result, the overall apparatus can be made compact, and an electric fan dedicated to the capacitor is not required, so that the apparatus can be simplified and power consumption can be reduced.

《Water server》
The present invention can be grasped as a water server using the above-described fresh water generator. That is, the present invention may be provided with a water source and a water injector for pouring water from the water source, and the water source may be a water server including the above-described water generator.

It is preferable that the water server of the present invention includes a water temperature regulator that cools and / or heats the water supplied from the fresh water generator (the water storage tank). The cooling can be performed using, for example, heat absorption (heat transfer) by an electronic cooler (for example, a Peltier element). Heating can be performed using, for example, electric heat or heat radiation (heat transfer) by a Peltier element. In this way, the condensed water obtained by the fresh water generator can be supplied as cold water and / or hot water while reducing the overall size of the device. The water temperature regulator may be provided with at least one of such a heater (heater) and a cooler (cooler), but the heat efficiency of the water temperature regulator can also be increased by utilizing heat transfer between the two. The water injector is, for example, a water injection cock (lever, dial) used when pouring hot water and / or cold water into a cup or the like.

It is a circuit block diagram of the fresh water generator which is one Example of this invention. It is the disassembled perspective view which looked at the fresh water generator from the front. It is a disassembled perspective view of the main body built in the fresh water generator. It is the disassembled perspective view which looked at the main body from back. It is a front view of the filter case built in the main body. It is a front view of the filter case which shows the modification which provided the baffle plate. It is AA sectional drawing which shows the modification provided with the air purifying filter. It is a circuit block diagram of a water server.

One or two or more components arbitrarily selected from the present specification can be added to the above-described components of the present invention. Even if it is a method component, it can become a component regarding the fresh water generator of this invention under fixed requirements. Which embodiment is the best depends on the required performance, application, and the like.

(1) Heat exchanger The fresh water generator of the present invention is disposed between the second compartment of the filter case and the condenser, and the working air that has flowed out of the condenser by the working air (hot humid air) that has flowed out of the second compartment. It is preferable to provide a heat exchanger for heating (low temperature dry air).

The working air (humid air) flowing out from the second section is in a high temperature state because it is heated air that has passed through the removable filter. The moist air is introduced into the condenser after being cooled in advance by working air (referred to as “dry air”) flowing out of the low-temperature condenser in the heat exchanger. For this reason, the humid air is sufficiently cooled to the dew point by the condenser, so that sufficient condensed water can be stably generated.

Conversely, the low temperature dry air is heated by the high temperature wet air and then guided to the electric heater. For this reason, it becomes possible to obtain hot air with a large amount of water vapor by flowing higher temperature heated air into the detachable filter in the second section while suppressing power consumption by the electric heater.

(2) Power supply The fresh water generator of the present invention performs movement of the removable filter, flow of raw material air and working air, and heating of working air with electric power. As this power source, a power source that can be easily procured at home or the like is sufficient. The power source may be a commercial power source supplied from an electric power company. Moreover, it is preferable to provide solar power generation and / or a storage battery as a power source because the fresh water generator of the present invention can be used in various regions and places and under various conditions. In particular, it is preferable that a commercial power source can be used as a main power source, and solar power generation and / or a storage battery can be used as a backup power source, because the range in which the fresh water generator can be used is expanded.

(3) Cock and filter The condensed water produced by the fresh water generator of the present invention is stored in a water storage tank. It is preferable that the water storage tank is detachable so that the water storage tank can be replaced or the water stored in the water storage tank can be moved to another container or the like when the amount of water stored in the water storage tank reaches a certain level or more. In addition, it is convenient that the user can use the fresh water generator of the present invention as it is as a water source or the like if a cock that can take or stop the water storage of the water storage tank as appropriate is provided.

Since the condensed water obtained by the fresh water generator of the present invention is purified water obtained from water vapor, it is basically clean. As long as the environment of the atmosphere (also referred to as “atmosphere” in this specification) in which the fresh water generator is placed is not contaminated, the water stored in the water storage tank can be used as it is as drinking water. However, it is more preferable that the fresh water generator of the present invention includes a water purification filter that removes bacteria or impurities contained in the water stored in the water storage tank. As a result, the water stored in the water storage tank can be used more safely for beverages in various places and environments.

The water purification filter may be a commercially available general-purpose filter or a dedicated filter that removes specific bacteria or impurities. Moreover, the water purification filter should just be arrange | positioned in the downstream from which condensed water produces | generates, for example, the inside of a water storage tank may be sufficient, and the upstream or downstream side of a cock may be sufficient.

(4) Air purifying filter The air purifying filter removes dust, dust, particles, bacteria, viruses, etc. from the surrounding air where the fresh water generator is installed, and cleans the air. The air purifying filter is disposed, for example, inside the fresh water generator or on the wall surface of the housing. The intake of air into the air purification filter may use a dedicated fan. However, if the first electric fan or the second electric fan according to the present invention is also used, the fresh water generator can be simplified and made compact. Desirable.

It is preferable that the air purifying filter is disposed upstream of the detachable filter. As a result, the raw material air taken into the fresh water generator is purified, and in addition to the air purification of the outside world, it is possible to purify the condensed water and take measures against contamination of the fresh water generator.

¡One or more air purifying filters are selected according to the collected matter. For example, a coarse filter (prefilter) that removes relatively large dust, dust, pollen, etc., a fine filter that removes particulates such as PM2.5, and a fine filter that removes bacteria, viruses, etc. You may use it combining a filter etc. suitably. By using a multilayer filter as the air cleaning filter, it is possible to efficiently purify air while suppressing pressure loss of the air flow. As the multilayer filter, a plurality of individual filters may be stacked, or a filter previously formed into a multilayer structure may be used.

Such filters are also defined in, for example, JIS (Z8122) and include HEPA filters (High Efficiency Particulate Air Filters), ULPA filters (Ultra Low Low Penetration Air Filters), and the like. In addition, in order to improve the effect of sterilization and sterilization, an ozone generator may be further provided on the downstream side of the air purification filter.

[Fresh water generator]
A fresh water producing apparatus 1 according to one embodiment (first embodiment) of the present invention is shown in FIGS. FIG. 1 is a circuit configuration diagram of the fresh water generator 1, FIG. 2 is an exploded perspective view of the fresh water generator 1 as viewed from the front, and FIG. 3 is an exploded perspective view of a main body 30 built in the fresh water generator 1. 4 is an exploded perspective view of the main body 30 as viewed from the rear, and FIG. 5 is a schematic view of the filter case 31 built in the main body 30 as viewed from the front. In FIGS. 3 and 4, for convenience of explanation, a part of the material part on the outside is broken and a member on the inside is shown.

"Overview"
(1) Configuration As shown in FIG. 1, the fresh water generator 1 includes a raw material flow path X (first flow path) that is a flow path of raw material air serving as a supply source of water vapor that is adsorbed to the removable filter 2, and the removable filter 2. And a generation flow path Y (second flow path) that generates condensed water by desorbing (releasing) water vapor.

The detachable filter 2 is composed of a disk-shaped rotor and is rotatably accommodated in the filter case 31. After the raw material air in the raw material flow path X is sucked from the atmosphere by the electric intake / exhaust fan 3 (first electric fan) and passes through the removable filter 2 in the suction opening 38 (first section) of the filter case 31. Exhaust into the atmosphere. The working air in the generation flow path Y is closed by returning from the downstream side to the upstream side of the removable filter 2 in the attachment / detachment opening 39 (second section) of the filter case 31 by the electric circulation fan 4 (second electric fan). It is circulating.

The generation flow path Y includes an electric heater 5 for heating the working air (dry air) upstream of the desorption opening 39 (before passing through the removable filter 2), and a downstream side of the desorption opening 39 (passing through the removable filter 2). A condenser 6 that cools and condenses the latter working air (humid air) is disposed. Further, a heat exchanger 7 for heat recovery is disposed in the generation flow path Y between the desorption opening 39 and the condenser 6.

In the heat exchanger 7, the high-temperature portion 9 of the generation flow path Y through which the high-temperature working air (humid air) that has passed through the detachable filter 2 flows, and the low-temperature working air (dry air) before passing through the detachable filter 2 flows. Heat exchange is performed with the low temperature portion 8 of the generation flow path Y. Thus, the working air (dry air) flowing into the desorption opening 39 is preheated (warmed) before being introduced into the electric heater 5. As a result, while suppressing the power consumption of the electric heater 5, it is possible to efficiently raise the temperature of the working air that passes through the attachment / detachment filter 2 of the attachment / detachment opening 39, and thus it is possible to achieve both energy saving and improvement of fresh water generation performance.

(2) Operation The detachable filter 2 is driven by an electric motor (including a speed reducer) at a gradual speed of, for example, about 1 rotation within 3 minutes in the filter case 31, and continuously rotates. The raw material air sucked into the raw material flow path X of the fresh water generator 1 by the intake / exhaust fan 3 is introduced into a fan-shaped adsorption opening 38 that opens over a predetermined rotation region of the detachable filter 2. As a result, water vapor in the raw material air is adsorbed by the removable filter 2 rotating in the opening region, and the raw material air that has passed through the removable filter 2 is exhausted to the atmosphere.

The removable filter 2 that has adsorbed water vapor enters a desorption opening 39 formed adjacent to the adsorption opening 38. The detachable opening 39 also has a fan shape that opens over a predetermined rotation region of the detachable filter 2. The working air circulated through the production flow path Y by the circulation fan 4 is heated by the heat exchanger 7 and the electric heater 5 and introduced into the desorption opening 39 to desorb (spread or release) water vapor from the removable filter 2. The removable filter 2 from which the water vapor has been desorbed (regenerated) enters the adsorption opening 38 again, and adsorbs the water vapor in the raw material air as described above.

The working air (moisture air) containing water vapor desorbed from the removable filter 2 in the desorption opening 39 is primarily cooled by the heat exchanger 7 and then further cooled by the condenser 6 to generate condensed water. The condensed water is dropped on the drain pan 34 (see FIGS. 2 and 3) and stored in the water storage tank 26. By opening and closing the cock 27, the water can be taken in or stopped. The working air that has passed through the condenser 6 is preheated by the heat exchanger 7, then heated by the electric heater 5, and again introduced into the desorption opening 39.

<Details>
Below, the specific structure of the fresh water generator 1 is demonstrated in detail. In addition, the same code | symbol is attached | subjected to the thing similar to the member or structure mentioned above also including the other Example (modification) mentioned later, and the detailed description is abbreviate | omitted. In FIGS. 2 to 5, the flow path of the raw material air (raw material flow path X) is indicated by a thick hollow arrow, and the flow path of the working air (generation flow path Y) is indicated by a solid thick arrow.

Incidentally, the flow direction of the raw material air and the working air in the condenser 6 and the heat exchanger 7 may be countercurrent, parallel flow or direct current. Heat exchange efficiency can be improved by making the flow direction countercurrent, and compactness can be achieved by making it parallel or direct current. For convenience of explanation, FIG. 1 shows a case where the flow direction is countercurrent, but the actual flow direction is cocurrent or direct current. This is because the amount of air leakage in the vicinity of the detachable filter 2 can be reduced by using a parallel flow rather than a counter flow.

(1) Structure As shown in FIG. 2, the fresh water generator 1 is configured such that a main body 30 is accommodated in a vertically long and wide casing 23 including a front cover 231, a case 232, and a top cover 233. On the upper side of the front cover 231, there is provided an operation panel 21 having a power switch of the fresh water generator 1 and an indicator showing its operating state. On one side surface (left side surface in FIG. 2) of the case 232, an air inlet 24 is formed for sucking raw material air from the atmosphere into the inside. On the top surface of the top cover 233, an exhaust port 25 for discharging the raw air after adsorbing water vapor is formed. The exhaust port 25 communicates with an exhaust port 51 of an intake / exhaust fan housing chamber 49 described later by a duct 22 provided in the upper part of the case 232. A water storage tank 26 that can be pulled out and removed is housed in the lower portion of the housing 23. The water storage tank 26 is provided with a water purification filter 28 and a cock 27. The condensed water in the water storage tank 26 is supplied through the cock 27 as clean drinking water that has passed through the water purification filter 28.

As shown in FIGS. 2 to 5, the main body 30 includes a removable filter 2 accommodated in a filter case 31, an intake / exhaust fan 3 and a circulation fan 4 accommodated in a fan casing 32, a condenser 6, a heat exchanger 7 and a drain pan. 34.

The removable filter 2 includes a disk-shaped substrate (honeycomb, filter paper, nonwoven fabric, etc.) through which air can be inserted in the direction of the rotation axis, and an adsorbent (zeolite, silica gel, lithium chloride, calcium chloride, etc.) carried on the surface or inside thereof. And a ring-shaped frame that accommodates the base body. The detachable filter 2 has a frame whose rotation axis is pivotally supported by the filter case 31 and is driven to rotate by a motor 37 via a speed reduction mechanism (not shown). The detachable filter 2 rotates counterclockwise when viewed from the front at a moderate speed of about one rotation in about 3 minutes, for example (see FIG. 5).

The filter case 31 includes a flat plate portion 35 disposed opposite to a side surface (the intake port 24 side) of the case 232, and a filter storage portion 36 that rotatably stores the detachable filter 2 on the rear surface side of the flat plate portion 35. The filter case 31 has an adsorption opening 38 through which the raw air passes and a desorption opening 39 through which the working air passes. The suction opening 38 and the attachment / detachment opening 39 are fan-shaped openings that pass through the filter case 31 in the front-rear direction (rotational axis direction of the removable filter 2), and are disposed adjacent to each other in the rotational direction of the removable filter 2. Yes. Corresponding to these opening regions, predetermined ranges of the front surface 2a and the rear surface 2b of the removable filter 2 are exposed. Specifically, the adsorption opening 38 opens over a range of about 2/3 of the detachable filter 2 (about 240 ° in the central angle), and the detachable opening 39 is about the remaining about the remaining of the detachable filter 2. The opening is made over a range of 1/3 (about 120 ° in the central angle).

The heat exchanger 7 has a low temperature part 8 and a high temperature part 9 and is accommodated in a heat exchanger accommodating chamber 40 at the top of the filter case 31. The low temperature part 8 and the high temperature part 9 are configured by a plurality of juxtaposed pipes 42 (partition wall parts) that penetrate between the opposing support walls 41 and are held in a lateral direction (substantially horizontal direction) at a predetermined interval. ing. Specifically, the pipe 42 causes the low temperature portion 8 (inside the pipe 42) through which the working air flowing into the desorption opening 39 passes, and the high temperature portion 9 (pipe 42) through which the working air flowing out from the desorption opening 39 passes. Outside). The heat exchanger accommodating chamber 40 is partly connected to the condenser 6 from the high temperature portion 9 by closing the upper portion of the heat exchanger accommodating chamber 40 with a lid body 43.

The electric heater 5 generates heat when supplied with power and heats the working air flowing into the attachment / detachment opening 39. The electric heater 5 is disposed on the front side of the filter case 31 and is accommodated in the upstream cover member 44. The upstream cover member 44 divides between the suction opening 38 and the desorption opening 39 on the front side of the filter case 31 and between the low temperature portion 8 of the heat exchanger housing chamber 40 and the upstream side of the desorption opening 39. Is in communication.

The capacitor 6 is disposed in front of the suction opening 38 and penetrates between the support walls 45 facing each other, and is arranged in parallel with a plurality of pipes that are held in a vertical direction (vertical oblique direction) at a predetermined interval. 46. The upper part of the condenser 6 communicates with the high temperature part 9 of the heat exchanger accommodating chamber 40, and the working air (wet air) passing through the attachment / detachment filter 2 of the attachment / detachment opening 39 and passing through the heat exchanger 7 is inside the pipe 46. Flow into. On the other hand, the raw material air sucked from the atmosphere (the raw material air before flowing into the adsorption opening 38) passes through the outside of the pipe 46.

Thus, the working air (humid air) is cooled by the low-temperature raw material air when passing through the pipe 46, and the water vapor contained therein becomes condensed water in the pipe 46. Here, the pipe 46 of the capacitor 6 is attached to the filter case 31 in a posture state slightly inclined with respect to the vertical direction (for example, an inclination angle of about 15 °). For this reason, the condensed water in the pipe 46 flows down without staying in the pipe 46.

The condensed water flowing down in the pipe 46 is received by the drain pan 34 provided at the lower part of the condenser 6. The drain pan 34 has a drain hole 47 that guides the accumulated condensed water to the water storage tank 26, and a duct 48 that guides the working air (dry air) flowing into the drain pan 34 to the pipe 42 side of the heat exchanger 7. . The drain hole 47 is provided with a mechanism for collecting only condensed water in the water storage tank 26 without passing the working air.

A downstream cover member 50 and a fan casing 32 are disposed on the rear side of the filter case 31. The downstream cover member 50 partitions the adsorption opening 38 and the desorption opening 39 from each other, and communicates the downstream side of the desorption opening 39 and the high temperature portion 9 of the heat exchanger housing chamber 40. The fan casing 32 forms an intake / exhaust fan accommodating chamber 49 for accommodating the intake / exhaust fan 3 in cooperation with the filter case 31. The intake / exhaust fan housing chamber 49 has a discharge port 51 for discharging the raw air that has passed through the detachable filter 2 in the upper portion, and the discharge port 51 communicates with the exhaust port 25 of the housing 23.

The rear surface of the fan casing 32 and the fan cover 33 form a circulation fan housing chamber 52 that houses the circulation fan 4. The upper part of the circulation fan housing chamber 52 communicates with the heat exchanger housing chamber 40. The lower part of the circulation fan accommodating chamber 52 communicates with the duct 48 of the drain pan 34 (see FIG. 4). The intake / exhaust fan 3 and the circulation fan 4 are disposed on the front side and the rear side of the fan casing 32, respectively, and both are connected coaxially and driven to rotate by a single electric motor (not shown).

(2) Airflow First, raw air is sucked into the housing 23 from the air inlet 24 by the operation of the intake / exhaust fan 3. The raw material air passes through the gap between the pipes 46 of the condenser 6 and flows into the detachable filter 2 in the adsorption opening 38 (first section). The raw material air that has passed through the detachable filter 2 flows into the intake / exhaust fan housing chamber 49, and is exhausted from the exhaust port 51 at the top thereof to the air through the exhaust port 25. By such a path of the raw material air, a raw material flow path X (see FIG. 1) indicated by a hollow arrow in each figure is formed.

Next, due to the operation of the circulation fan 4, the working air in the circulation fan accommodation chamber 52 is sent out from the upper part of the circulation fan accommodation chamber 52 and passes through the low temperature part 8 (inside the pipe 42) of the heat exchanger accommodation chamber 40. Then, the filter case 31 moves from the rear surface side to the front surface side and flows into the upstream cover member 44. The working air in the upstream cover member 44 is heated by the electric heater 5, and then flows from the front surface 2a side to the rear surface 2b side of the detachable filter 2 in the desorption opening 39 (second section). The working air that has passed through the detachable filter 2 rises in the downstream cover member 50, flows into the heat exchanger accommodating chamber 40 from below, and extends in the longitudinal direction of the high temperature portion 9 (outside the pipe 42) of the heat exchanger 7. Pass through. Thereafter, the working air flows out from the downstream portion 9b of the high temperature portion 9, flows into the pipe 46 of the condenser 6, and is cooled by the raw air passing through the gap of the pipe 46 from the front side to the rear side. The cooled working air (dry air) returns to the circulation fan accommodating chamber 52 through the duct 48 again. A generation flow path Y (see FIG. 1) indicated by a solid thick arrow in each figure is formed by such a working air path.

(3) Heat Exchange In the case of the fresh water generator 1, as shown in FIG. 5, the working air that has passed through the attachment / detachment filter 2 in the attachment / detachment opening 39 passes along the attachment / detachment filter 2 from the side surface portion 7 </ b> A of the heat exchanger 7. After flowing into the high temperature part 9 and flowing through the gap between the pipes 42 on the outer peripheral side of the detachable filter 2, it flows out from the downstream end face part 7 </ b> B in the longitudinal direction of the heat exchanger 7.

By the way, the detachable filter 2 is rotating in the direction opposite to the flow direction of the working air flowing in the high temperature part 9 (counterclockwise shown in FIG. 5). For this reason, in the attachment / detachment opening 39, the working air that has passed through the preceding region H located in front of the attachment / detachment filter 2 in the rotation direction flows into the upstream portion 9a side of the side surface portion 7A. On the other hand, the working air that has passed through the trailing region C located behind the rotational direction of the detachable filter 2 flows into the downstream portion 9b side of the side surface portion 7A and passes through the heat exchanger 7 in a short time.

Here, the preceding region H is longer in the desorption opening 39 than the trailing region C, has a small amount of evaporation, and is less likely to lose heat of vaporization. Therefore, the preceding area H is hotter than the following area C, and the working air passing through the preceding area H is higher in temperature than the working air passing through the following area C.

Therefore, in the fresh water generator 1 of the present embodiment, the high-temperature working air has a long passage time through the heat exchanger 7, and the low-temperature working air has a short passage time through the heat exchanger 7. Efficiency is improved. As a result, the working air before passing through the electric heater 5 is efficiently heated by the heat exchanger 7, while the power consumption of the electric heater 5 is suppressed, and a sufficiently high temperature working air is attached to and detached from the attachment / detachment opening 39. Guided to filter 2. For this reason, the fresh water generator 1 exhibits high fresh water generation performance while suppressing power consumption.

<Modification>
(1) As shown in FIG. 6, the fresh water generator 1 may be provided with a rectifying plate 53 in the downstream cover member 50 on the downstream side of the attachment / detachment opening 39. The rectifying plate 53 is a partition curved in an arc shape from the vicinity of the center of the detachable filter 2 to the vicinity of the upstream portion 9a of the high temperature portion 9 through the outer peripheral side. The downstream cover member 50 is partitioned by the current plate 53 into a preceding region H side and a following region C side. As a result, the high temperature working air that has passed through the preceding region H may be mixed with the low temperature working air that has passed through the following region C before the temperature reaches the high temperature portion 9 of the heat exchanger 7 and the temperature may be lowered. Is prevented. That is, only the high temperature working air that has passed through the preceding region H is positively guided to the upstream portion 9a of the high temperature portion 9 and reliably flows into the upstream portion 9a.

(2) As described above, the removable filter 2 may be arranged in the horizontal direction in addition to being arranged in the vertical direction. Further, the condenser 6 or the heat exchanger 7 is not limited to the direct current type, and may be a countercurrent type or a parallel flow type.

(3) It is preferable that the fresh water generator 1 is continuously operated in a dry mode in which the inside is dried in order to prevent generation of mold and the like after turning off the power switch (fresh water mode). The drying mode can be performed, for example, by operating the intake / exhaust fan 3, the circulation fan 4, and the motor 37 for a predetermined time with the electric heater 5 turned off. When the operation is stopped, the generation flow path Y (second flow path) is higher in humidity than the raw material flow path X (first flow path), but by operating in the above-described drying mode, the generation flow path Y The water vapor in the (second flow path) is absorbed by the removable filter 2 and then released from the raw material flow path X (first flow path).

In addition, as a drying mode, an open / close valve may be provided in the drain hole 47, and the valve may be fully opened during drying. At this time, just by operating the intake / exhaust fan 3 and the circulation fan 4, the air outside the fresh water generator 1 is sucked into the generation flow path Y (second flow path) from the drain hole 47 and is around the removable filter 2. It discharges | emits from the raw material flow path X (1st flow path) through a clearance gap. Thus, the inside of the generation flow path Y is dried by the air sucked from the outside. In this case, the larger the drain hole 47, the faster the drying mode can be performed. However, if the drain hole 47 becomes excessive, air tends to flow from the outside of the apparatus into the apparatus during fresh water generation. Therefore, it is preferable to adjust the degree of opening of the drain hole 47 by an on-off valve. For example, it is preferable that the opening of the drain hole 47 is narrowed to the extent that a water film can be formed during fresh water formation and the entire opening of the drain hole 47 can be opened during the drying mode.

(4) As shown in FIG. 7, the fresh water generator 1 may be provided with an air purifying filter F inside the air inlet 24 on the side surface of the case 232. The air purification filter F is a fine first particle filter f1 that collects dust, pollen, etc. from the air around the fresh water generator 1, and fine particles such as PM2.5 from the air that has passed through the first gas filter f1. Is a multi-layer filter in which a fine second cleaning filter f2 that collects water is laminated. The first cleaning filter f1 is, for example, a prefilter or a deodorizing filter, and the second cleaning filter f2 is, for example, a medium performance filter, a HEPA filter, or the like.

The air purifying filter F is accommodated in a window frame 241 provided inside the case 232. The air purifying filter F may be removable from the front cover 231 side, or may be removable from the outside of the case 232 as shown in FIG. In any case, it is preferable that the cartridge is replaceable because maintenance is easy.

By providing such an air purification filter F in the fresh water generator 1, clean air is supplied to the raw material flow path X, and purified air is discharged from the exhaust port 25 to the outside of the fresh water generator 1. The As a result, it is possible to purify the air in the space where the fresh water generator 1 is installed, as well as to prevent the generated condensed water and contamination in the fresh water generator 1.
