Description

INDUSTRIAL APPLICABILITY According to the present invention, water can be obtained from air in the atmosphere as a raw material, and in particular, a water production device or the like that can be easily installed in a home or the like and can stably obtain water suitable for drinking water or the like. Regarding.

Water is essential for the survival of living organisms, but the areas where a stable supply of water (especially water suitable for drinking water) is possible are limited. There are many places where it is difficult to obtain water suitable for drinking, not only in dry areas such as deserts, but also in areas and countries where water is abundant at first glance. For example, areas where sanitary environment is poor or rivers are polluted, remote islands where water supply is not fully equipped, etc.

Measures to obtain water suitable for drinking water in such a place include regeneration of sewage and desalination of seawater. However, such processing requires large-scale equipment and the like, and is not easy to introduce. In addition, since water (liquid) as a raw material is required in the first place, the area where it can be introduced is limited.

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

Special Publication No. 62-21566 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 obtained moist air is cooled to produce water. Patent Document 1 proposes a water-making device in which a flow path of air introduced into an adsorbent and a cooling flow path of moist air derived from the adsorbent are separated. Patent Document 2 proposes a water production device that can be operated without power supply by heating the air to be introduced into the adsorbent adsorbed with water vapor and supplying the air in each flow path by solar heat. ..

The water production device as in Patent Document 1 is large and difficult to spread to general households and the like. Further, a water production device as in Patent Document 2 is not preferable because the amount of water produced, which is 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 water production device or the like that can achieve both compactification and stabilization of water production amount and can be easily introduced into a home or the like. ..

As a result of diligent research to solve this problem, the present inventor has made it compact by moving the adsorbent, supplying air and heating with electric power, and devising a cooling structure for the moist air flowing out of the adsorbent. We have newly developed a water production device that can stabilize the amount of water production. By developing this result, the present invention described below was completed.

《Water production equipment》
(1) The water-producing device of the present invention accommodates a detachable filter that allows air to pass through while adsorbing or desorbing water vapor, and the detachable filter is accommodated and air is guided to the detachable filter to adsorb water vapor to the detachable filter. A filter case having a first compartment to be attached and a second compartment to desorb water vapor from the detachable filter, and an electric motor for continuously or intermittently moving the detachable filter between the first compartment and the second compartment. A first flow path that connects an intake port that is open to the atmosphere to an exhaust port that is open to the atmosphere through the first section, a first electric fan that flows air in the first flow path, and the like. A second flow path that returns from the downstream side to the upstream side of the second section, a second electric fan that flows the working air in the second flow path, and an electric heater that heats the working air that flows into the second section. A capacitor for obtaining condensed water by cooling the working air flowing out of the second section with the air passing through the first flow path, and a water storage tank for storing the condensed water are provided.

(2) According to the water making apparatus of the present invention, first, the attachment / detachment filter is driven, the air as a raw material is taken in and exhausted, and the working air is heated and flowed by using electric power. Therefore, as long as electric power can be supplied from a commercial power source, a storage battery, or the like, the water-producing device of the present invention continues to operate, and a stable water-producing amount can be secured.

Next, in the water-making device of the present invention, the removable filter is used to obtain condensed water by cooling the air (referred to as "moist air") obtained by permeating the heated working air through the removable filter that has adsorbed water vapor. The air taken in to adsorb water vapor (referred to as "raw material air") is used. As a result, the device as a whole can be made compact, and since an electric fan dedicated to the capacitor is not required, the device can be simplified and power consumption can be suppressed.

That is, the present invention includes a water source and a water injection device that injects water from the water source, and the water source may be a water server including the above-mentioned water production device.

It is preferable that the water server of the present invention is provided with a water temperature regulator that cools and / or heats the water conveyance supplied from the water production device (its water storage tank). Cooling can be performed by using, for example, heat absorption (heat transfer) by an electronic cooler (for example, a Pelche element). Heating can be performed by using, for example, electric heating, heat dissipation (heat transfer) by a Pelche element, or the like. In this way, the condensed water obtained by the water-making device can be supplied as cold water and / or hot water while making the entire device compact. The water temperature regulator may be provided with at least one of such a heater (heater) and a cooler (cooler), but the thermal efficiency of the water temperature regulator can also be increased by utilizing the heat transfer between the two.

One or more components arbitrarily selected from the present specification may be added to the above-mentioned components of the present invention. Even a methodical component can be a component related to the water production apparatus of the present invention under certain conditions. Which embodiment is the best depends on the required performance, application, and the like.

(1) Heat exchanger The water making apparatus of the present invention is arranged between the second compartment of the filter case and the condenser, and the working air flowing out of the condenser due to the working air (high temperature moist air) flowing out of the second compartment. It is preferable to provide a heat exchanger that heats (low temperature dry air).

The working air (moist air) that has flowed out of the second compartment is in a high temperature state because it is heated air that has passed through the removable filter. This moist air is pre-cooled by the working air (referred to as "dry air") flowing out of the low-temperature condenser in the heat exchanger, and then guided to the condenser. Therefore, as a result of the moist air being sufficiently cooled to the dew point by the condenser, sufficient condensed water can be stably generated.

On the contrary, the low-temperature dry air is heated by the high-temperature moist air and then guided to the electric heater. Therefore, it is possible to obtain moist air having a large amount of water vapor by allowing higher temperature heated air to flow into the detachable filter in the second compartment while suppressing the power consumption by the electric heater.

(2) Power supply In the water-making device of the present invention, the attachment / detachment filter is moved, the raw material air and the working air flow, and the working air is heated by 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 by an electric power company. Further, it is preferable to provide a solar power generation and / or a storage battery as a power source so that the water production apparatus of the present invention can be used in various areas 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 a solar power generation and / or a storage battery can be used as a backup power source, because the range in which the water-producing device can be used is expanded.

(3) Cock and filter Condensed water generated by the water-making device of the present invention is stored in a water storage tank. When the amount of water stored in the water storage tank exceeds a certain level, the water storage tank is preferably removable 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. Further, if the water storage of the water storage tank is appropriately provided with a cock capable of taking or stopping water, the user can conveniently use the water production device of the present invention as it is as a water source or the like.

The condensed water obtained by the water-making apparatus of the present invention is purified water obtained from steam, and is therefore basically clean. As long as the environment of the atmosphere in which the water production device is placed (also referred to as "atmosphere" in the present specification) 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 water production apparatus 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 drinking in various places and environments.

The water purification filter may be a commercially available general-purpose filter or a dedicated filter for removing specific bacteria or impurities. Further, the water purification filter may be arranged on the downstream side where condensed water is generated, and may be, for example, in a water storage tank, or on the upstream side or the downstream side of the cock.

(4) Air Purifying Filter The air purifying filter purifies the air by removing dust, dust, particles, bacteria, viruses, etc. from the surrounding air in which the water making device is arranged. The air purifying filter is arranged, for example, inside the water making apparatus, on the wall surface of the housing, or the like. A fan dedicated to the air may be taken into the air purifying filter, but if the first electric fan and the second electric fan according to the present invention are also used, the water production device can be simplified and made compact. It is preferable to plan.

The air purifying filter is preferably disposed on the upstream side of the removable filter. As a result, the raw material air taken into the water making equipment is purified, and in addition to purifying the air in the outside world, it is possible to purify the condensed water and take measures against pollution of the water making equipment.

As the air purifying filter, one or more types are selected according to the collected material. For example, a coarse filter (pre-filter) that removes relatively large dust, dust, pollen, etc., a fine filter that removes fine particles such as PM2.5, and a fine filter that removes bacteria, viruses, etc. (sterilization, sterilization, etc.) Filters and the like may be used in combination as appropriate. By using a multi-layer filter for the air purification filter, it is possible to efficiently purify the air while suppressing the 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 a filter is also specified in JIS (Z8122), for example, and includes a HEPA filter (High Efficiency Particulate Air Filter), a ULPA filter (Ultra Low Penetration Air Filter), and the like. In addition, in order to enhance the effect of sterilization and sterilization, an ozone generator may be further provided on the downstream side of the air cleaning filter or the like.

[Water making equipment]
The water production apparatus 1 which is an embodiment (first embodiment) of the present invention is shown in FIGS. 1 to 5. FIG. 1 is a circuit configuration diagram of the water production device 1, FIG. 2 is an exploded perspective view of the water production device 1 as viewed from the front, and FIG. 3 is an exploded perspective view of the main body 30 built in the water production device 1. FIG. 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 addition, in FIGS. 3 and 4, for convenience of explanation, a member inside is shown by breaking a part of the material portion on the outside.

"Overview"
(1) Configuration As can be seen from FIG. 1, the water making apparatus 1 has a raw material flow path X (first flow path), which is a flow path of raw material air that is a supply source of water vapor adsorbed on the removable filter 2, and a removable filter 2. It is provided with a generation flow path Y (second flow path) that desorbs (releases) water vapor from the water vapor to generate condensed water.

The detachable filter 2 is composed of a disk-shaped rotor, and is rotatably housed in the filter case 31. The raw material air in the raw material flow path X is taken in from the atmosphere by the electric intake / exhaust fan 3 (first electric fan), and after passing through the removable filter 2 in the suction opening 38 (first section) of the filter case 31. , Exhausted to the atmosphere. The working air of the generation flow path Y is returned from the downstream side to the upstream side of the detachable filter 2 in the desorption opening 39 (second section) of the filter case 31 by the electric circulation fan 4 (second electric fan) and closed. It is circulating.

In the generation flow path Y, an electric heater 5 for heating the working air (dry air) on the upstream side of the detachable opening 39 (before passing through the detachable filter 2) and the downstream side of the detachable opening 39 (passing through the detachable filter 2). A condenser 6 for cooling and condensing the working air (moist air) of the latter) is arranged. Further, in the generation flow path Y, a heat exchanger 7 for heat recovery is arranged between the detachable opening 39 and the capacitor 6.

In the heat exchanger 7, the high temperature portion 9 of the generation flow path Y through which the high temperature working air (moist air) that has passed through the removable filter 2 flows, and the low temperature working air (dry air) that has not passed through the removable filter 2 flow. Heat exchange is performed with the low temperature portion 8 of the generation flow path Y. As a result, the working air (dry air) flowing into the detachable opening 39 is preheated (heated) before being introduced into the electric heater 5. As a result, it is possible to efficiently raise the temperature of the working air passing through the detachable filter 2 of the detachable opening 39 while suppressing the power consumption of the electric heater 5, and it is possible to achieve both energy saving and improvement of water production performance.

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

The detachable filter 2 that has adsorbed water vapor enters the detachable 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 circulating in the generated 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 (dissipate or release) water vapor from the desorption filter 2. The detachable filter 2 from which the water vapor is desorbed (regenerated) re-enters the adsorption opening 38 and adsorbs the water vapor in the raw material air as described above.

The working air (moist air) containing water vapor desorbed from the desorption 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. This condensed water is dropped onto the drain pan 34 (see FIGS. 2 and 3) and stored in the water storage tank 26. By opening and closing the cock 27, it is possible to take in or stop the stored water. The working air that has passed through the condenser 6 is preheated by the heat exchanger 7, heated by the electric heater 5, and introduced into the detachable opening 39 again.

"detail"
The specific structure of the water making apparatus 1 will be described in more detail below. In addition, the same reference numerals are given to the members or structures similar to those described above, including other embodiments (modification examples) described later, and detailed description thereof will be omitted. Further, in FIGS. 2 to 5, the flow path of the raw material air (raw material flow path X) is indicated by a thick arrow, and the flow path of the working air (generation flow path Y) is indicated by a solid thick arrow.

Incidentally, the flow directions 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. The heat exchange efficiency can be improved by setting the flow direction to the countercurrent, and the compact size can be achieved by using the parallel flow or the direct current. In FIG. 1, for convenience of explanation, the case where those flow directions are countercurrent is shown, but the actual flow direction is parallel flow or direct current. This is because the amount of air leakage in the vicinity of the detachable filter 2 can be reduced by using parallel flow rather than countercurrent flow.

(1) Structure As shown in FIG. 2, the main body 30 of the water making apparatus 1 is housed in a vertically long and horizontally wide housing 23 including a front cover 231, a case 232, and a top cover 233. On the upper side of the front cover 231 is provided with an operation panel 21 having a power switch of the water making apparatus 1 and an indicator indicating the operating state thereof. On one side surface (left side surface in FIG. 2) of the case 232, an intake port 24 for sucking raw material air from the atmosphere into the inside is formed. An exhaust port 25 for discharging raw material air after adsorbing water vapor is formed on the upper surface of the top cover 233. The exhaust port 25 communicates with the exhaust port 51 of the intake / exhaust fan accommodating chamber 49, which will be described later, by a duct 22 provided above the inside of the case 232. A water storage tank 26 that can be pulled forward and removed is housed in the lower part 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 housed in a filter case 31, an intake / exhaust fan 3 and a circulation fan 4 housed in a fan casing 32, a capacitor 6, a heat exchanger 7, and a drain pan. Has 34.

The detachable filter 2 is a disk-shaped substrate (honeycomb, filter paper, non-woven 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.) supported on the surface or inside thereof. ) And a ring-shaped frame for accommodating the substrate. The rotation axis of the frame of the detachable filter 2 is pivotally supported by the filter case 31, and is driven by a motor 37 via a deceleration mechanism (not shown). The detachable filter 2 rotates counterclockwise when viewed from the front, for example, at a gentle speed of about one rotation in about 3 minutes (see FIG. 5).

The filter case 31 has a flat plate portion 35 arranged to face the side surface (intake port 24 side) of the case 232, and a filter accommodating portion 36 rotatably accommodating the detachable filter 2 on the rear surface side of the flat plate portion 35. Further, the filter case 31 has a suction opening 38 through which the raw material air passes and a desorption opening 39 through which the working air passes. The suction opening 38 and the detachable opening 39 are fan-shaped openings that penetrate the filter case 31 in the front-rear direction (rotational axis direction of the detachable filter 2), and are arranged adjacent to each other with respect to the rotational direction of the detachable filter 2. There is. A predetermined range of the front surface 2a and the rear surface 2b of the detachable filter 2 is exposed corresponding to those opening regions. Specifically, the suction opening 38 is open over a range of about 2/3 of the detachable filter 2 (about 240 ° at the central angle), and the detachable opening 39 is the remaining portion of the detachable filter 2. It is open over a range of 1/3 (about 120 ° at the central angle).

The heat exchanger 7 has a low temperature section 8 and a high temperature section 9, and is housed in the heat exchanger storage chamber 40 at the upper part of the filter case 31. The low temperature portion 8 and the high temperature portion 9 are composed of a plurality of juxtaposed pipes 42 (partition wall portions) that penetrate between the facing support walls 41 and are held laterally (substantially horizontal direction) at predetermined intervals. ing. Specifically, the low temperature portion 8 (inside the pipe 42) through which the working air flowing into the desorption opening 39 by the pipe 42 passes, and the high temperature portion 9 (the pipe 42) through which the working air flowing out from the desorption opening 39 passes. The outside) and are formed. The heat exchanger accommodating chamber 40 forms a part of the communication passage from the high temperature portion 9 to the capacitor 6 by closing the upper portion thereof with the lid 43.

The electric heater 5 receives power and generates heat, and heats the working air flowing into the detachable opening 39. The electric heater 5 is arranged on the front side of the filter case 31 and is housed in the upstream cover member 44. The upstream cover member 44 partitions between the suction opening 38 and the detachable opening 39 on the front side of the filter case 31, and is between the low temperature portion 8 of the heat exchanger accommodating chamber 40 and the upstream side of the detachable opening 39. Is communicating.

The condenser 6 is arranged in front of the suction opening 38, and a plurality of juxtaposed pipes that penetrate between the facing support walls 45 and are held in the vertical direction (vertically diagonal direction) at predetermined intervals. It consists of 46. The upper part of the condenser 6 communicates with the high temperature portion 9 of the heat exchanger accommodating chamber 40, and the working air (moist air) that has passed through the detachable filter 2 of the detachable opening 39 and passed through the heat exchanger 7 is inside the pipe 46. Inflow to. On the other hand, the raw material air sucked from the atmosphere (the raw material air before the inflow of the adsorption opening 38) passes through the outside of the pipe 46.

In this way, the working air (moist air) is cooled by the low-temperature raw material air as it passes 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 slightly inclined with respect to the vertical direction (for example, an inclination angle of about 15 °). Therefore, 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 in 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) that has flowed 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 allowing the working air to pass therethrough.

A downstream cover member 50 and a fan casing 32 are arranged on the rear side of the filter case 31. The downstream cover member 50 partitions between the suction opening 38 and the detachable opening 39, and communicates the downstream side of the detachable opening 39 with the high temperature portion 9 of the heat exchanger accommodating chamber 40. The fan casing 32 cooperates with the filter case 31 to form an intake / exhaust fan accommodating chamber 49 for accommodating the intake / exhaust fan 3. The intake / exhaust fan accommodating chamber 49 has an exhaust port 51 at the upper part for discharging the raw material air that has passed through the removable filter 2, and the exhaust 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 accommodating chamber 52 for accommodating the circulation fan 4. The upper part of the circulation fan accommodating chamber 52 communicates with the heat exchanger accommodating chamber 40. The lower portion 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 arranged on the front side and the rear side of the fan casing 32, respectively, and both are coaxially connected and rotationally driven by one electric motor (not shown).

(2) Airflow First, by operating the intake / exhaust fan 3, the raw material air is sucked into the housing 23 from the intake port 24. The raw material air passes through the gap of the pipe 46 of the condenser 6 and flows into the detachable filter 2 in the suction opening 38 (first section). The raw material air that has passed through the removable filter 2 flows into the intake / exhaust fan accommodating chamber 49, and is exhausted into the atmosphere from the exhaust port 51 at the upper part of the intake / exhaust fan accommodating chamber 49 through the exhaust port 25. By such a path of raw material air, a raw material flow path X (see FIG. 1) indicated by a thick arrow is formed in each figure.

Next, by the operation of the circulation fan 4, the working air in the circulation fan accommodating chamber 52 is sent out from the upper part of the circulation fan accommodating chamber 52 and passes through the low temperature portion 8 (inside the pipe 42) of the heat exchanger accommodating chamber 40. Then, it moves from the rear surface side to the front surface side of the filter case 31 and flows into the upstream cover member 44. After being heated by the electric heater 5, the working air in the upstream cover member 44 flows from the front surface 2a side to the rear surface 2b side of the attachment / detachment filter 2 in the attachment / detachment 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 of the pipe 42) of the heat exchanger 7. Pass through. After that, 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 material 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. By such a path of the working air, a generation flow path Y (see FIG. 1) indicated by a solid thick arrow in each figure is formed.

(3) Heat exchange In the case of the water making apparatus 1, as shown in FIG. 5, the working air that has passed through the detachable filter 2 in the detachable opening 39 is sent from the side surface portion 7A of the heat exchanger 7 along the detachable filter 2. It flows into the high temperature portion 9, flows through the gap between the pipes 42 on the outer peripheral side of the detachable filter 2, and then flows out from the downstream end face portion 7B in the longitudinal direction of the heat exchanger 7.

By the way, the detachable filter 2 rotates in a direction opposite to the flow direction of the working air flowing in the high temperature portion 9 (counterclockwise shown in FIG. 5). Therefore, 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 attachment / detachment filter 2 in the rotational direction 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 leading region H has a longer staying time in the desorption opening 39 than the trailing region C, the amount of evaporation is small, and the heat of vaporization is less likely to be taken away. Therefore, the leading region H has a higher temperature than the trailing region C, and the working air passing through the leading region H has a higher temperature than the working air passing through the trailing region C.

Therefore, in the water making apparatus 1 of the present embodiment, the high temperature working air has a long passage time of the heat exchanger 7, and the low temperature working air has a short passage time of the heat exchanger 7. Efficiency has been improved. As a result, the working air before passing through the electric heater 5 is efficiently heated by the heat exchanger 7, and the sufficiently high temperature working air is attached to and detached from the detachable opening 39 while suppressing the power consumption of the electric heater 5. Guided to filter 2. Therefore, the water production device 1 exhibits high water production performance while suppressing power consumption.

<< Modification example >>
(1) As shown in FIG. 6, the water making apparatus 1 may be provided with a straightening vane 53 in the downstream cover member 50 on the downstream side of the detachable opening 39. The straightening vane 53 is a partition curved in a bow 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 via the outer peripheral side. The inside of the downstream cover member 50 is partitioned by the straightening vane 53 into the leading region H side and the trailing 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 trailing region C before reaching the high-temperature portion 9 of the heat exchanger 7, and the temperature may drop. Be 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 surely flows into the upstream portion 9a.

(2) As described above, the detachable filter 2 may be arranged in the vertical direction or in the horizontal direction. Further, the capacitor 6 or the heat exchanger 7 is not limited to the DC type, and may be a countercurrent type or a parallel flow type.

(3) After turning off the power switch (water production mode), the water production device 1 preferably continues to operate in a drying mode in which the inside is dried in order to prevent the generation of mold and the like. The drying mode can be performed, for example, by turning off the electric heater 5 and operating the intake / exhaust fan 3, the circulation fan 4, and the motor 37 for a predetermined time. When the operation is stopped, the humidity in the generation flow path Y (second flow path) is higher than that in the raw material flow path X (first flow path), but by operating in the above-mentioned drying mode, the generation flow path Y The water vapor in the (second flow path) is absorbed by the detachable filter 2 and then discharged from the raw material flow path X (first flow path).

In addition, as a drying mode, an on-off valve may be provided in the drain hole 47, and the valve may be fully opened during drying. At this time, simply by operating the intake / exhaust fan 3 and the circulation fan 4, the air outside the water making device 1 is sucked into the generation flow path Y (second flow path) from the drain hole 47 and is around the attachment / detachment filter 2. It is discharged from the raw material flow path X (first flow path) through the gap. In this way, 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 into the device from the outside of the device during water production. Therefore, it is preferable to adjust the opening degree of the drain hole 47 by the on-off valve.
