Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry ventilating device for making a room a dry atmosphere while ventilating.

[0002]

2. Description of the Related Art As a device of this kind described above, for example, a dry ventilation device is known which makes a bathroom a dry atmosphere and can be used as a drying room for clothes and the like. A general dry ventilator has a configuration as disclosed in JP-A-4-240495. That is, it is constituted by a blower that circulates indoor air while being heated by the heating means, and a blower that intermittently discharges humid air inside the room to the outside.

This type requires a blower for circulation and a blower for exhaust, and since the amount of heat loss due to ventilation is large, the heating means also has a large capacity, and the overall size is large and the energy efficiency is also high. It's not very good. Therefore, Japanese Utility Model Laid-Open No. 6-10782 and Japanese Patent Laid-Open No. 7-180
As shown in Japanese Patent Publication No. 956, a device using a dehumidifying rotor capable of reversibly absorbing and releasing moisture has been developed.

[0004] The dehumidifying rotor itself used in this type of apparatus has been conventionally used for a plastic pellet drying apparatus and the like, and is formed by winding a corrugated material or a honeycomb material to which a hygroscopic agent such as silica gel is adhered. It has a cylindrical shape. As shown in FIG. 18, the dry ventilation device of the above publication includes a circulation air passage 102 for circulating the air in the room by a blower 101, and an exhaust air passage 103 opening to the outside.
The passage of the dehumidifying rotor 104 rotating at a low speed is the circulation air passage 10
2 and the exhaust air passage 103 are continuously passed.

A heating means 105 for dehumidifying the dehumidifying rotor 104 to regenerate its dehumidifying ability is provided at an inlet portion of the exhaust air passage 103 to the passage of the dehumidifying rotor 104, and a circulation air passage 102 is provided near the outlet thereof. A heating means 106 for heating is incorporated. In the illustrated device, a damper 107 that can switch the air passages between the blower outlet side of the blower 101 and the outdoor opening side of the exhaust air passage 103 or hold the damper 107 at a neutral position is provided on the blower side of the blower 101. The ventilation function, the drying function, or the heating function can be selectively performed by switching.

[0006]

The above-described conventional drying / ventilating apparatus using the dehumidifying rotor 104 has an air flow on the circulation air passage 102 side and an air flow on the exhaust side in the passage of the dehumidifier 104 during the drying operation. Since the air flows in parallel with each other, it is necessary to quickly raise the temperature of the air flow to be made to flow into the exhaust side by the heating means 105, and inevitably a large heating input is necessary.

Further, it is difficult to obtain a sufficient amount of air blown out from the circulation air passage 102 during the drying operation because it passes through the dehumidifying rotor 104, and the moisture stripping action from the surface of the object to be dried is weakened, and drying tends to occur. There is also a problem that it takes time. Furthermore, the dehumidifying rotor 10 can be operated even if only the ventilation function is used.
Since it is exhausted through the No. 4, the dehumidification rotor 104
Due to the large pressure loss, it was difficult to ventilate a large amount of air.

The present invention has been made in order to solve the above-mentioned conventional problems, and an object thereof is to obtain a drying ventilator having good energy efficiency for drying and shortening the drying time. , To obtain a dry ventilation device that can perform ventilation with a large air volume, to obtain a dry ventilation device that requires less heating input, and to obtain a dry ventilation device that can also perform a heating function with a simple configuration. , To obtain a dry ventilation device that is easy to install and has good applicability.

Embodiments of the present invention will now be described with reference to the drawings. First Embodiment of the Invention The dry ventilation device of the first embodiment shown in FIGS. 1 to 6 uses a dehumidifying rotor 1 having a reversible moisture absorption / desorption function. As shown in FIG. 3, the dehumidifying rotor 1 applied to this device is formed by winding a corrugated structure material 2 in which a hygroscopic agent such as silica gel is bonded to an inorganic fiber such as ceramics by using a polymerization reaction to form a columnar shape.
This is a configuration in which the multilayer passages 3 are concentrically formed. A rotation shaft of a motor 4 is attached to the center of the dehumidifying rotor 1, and the passages 3 are arranged in parallel with the rotation shaft. Each of the passages 3 is linear, and the open ends of the passages 3 face the dehumidifying rotor 1.

The dehumidifying rotor 1 having the above structure is rotatably mounted on a mounting base plate 6 provided in a main body casing 5, and is rotated at a low speed in a fixed direction by a motor 4 (from 0.5 rpm).
About 1 rpm). In the main body casing 5, a part of the path is constituted by a passage 3 of a specific area 7 of the dehumidifying rotor 1 (hereinafter referred to as dehumidifying area), and both ends serve as a suction port 8 and a blowout port 9, respectively. A circulation air passage 10 is formed which opens to the. A filter 11 is attached to the suction port 8 of the circulation air passage 10, and a blower 12 that forms an air flow toward the dehumidifying rotor 1 is attached to the back of the suction port 8 with the suction side facing the suction port 8. Circulation air passage 10 is suction port 8
Is formed as a series of passages from the blower 12 through the passage 3 in the dehumidifying area 7 of the dehumidifying rotor 1 to the air outlet 9 formed at the outlet end through the passage 3 formed in the mounting base plate 6. The air in the room circulates. In the dry ventilation device of the first embodiment, as shown in FIG. 5, the space is provided above the ceiling so that the suction port 8 and the air outlet 9 of the circulation air passage 10 are both separated from the lower surface of the main casing 5. Is provided.

The main casing 5 has an inlet opening to the circulation air duct 10 through a passage 3 in a specific region 13 (hereinafter referred to as a purge region) at a preceding stage in the rotation direction of the passage 3 of the dehumidification region 7 in the dehumidification rotor 1. A passage of another specific region 16 (hereinafter referred to as a regeneration region) of the preceding stage in the rotation direction of the purge region 13 of the dehumidifying rotor 1 via a heating path 15 having an end and provided with a heater 14 as a heating means. An exhaust air passage 17 having an outlet end that is open to the outside of the room is formed via the line 3. That is, as shown in FIG. 4, the end surface of the passage 3 of the dehumidifying rotor 1 facing the open end has a dehumidifying area 7 and a purging area 1.
3 and a reproduction area 16 are divided into three areas. The dehumidifying area 7 occupies the widest angle of about 230 degrees of the entire end face, the purging area 13 has an angle of about 50 degrees, and the regeneration area 16 has an angle of about 80 degrees.

The heating passage 15 of the exhaust air passage 17 is constituted by a heating box 18 mounted on the mounting base plate 6 on which one end surface of the dehumidifying rotor 1 slides in an airtight state. The heating box 18 has a purge region 13 on one end surface side of the dehumidifying rotor 1 through an opening formed in the mounting base plate 6.
The end of the passage 3 is connected to the end of the passage 3 of the reproduction area 16. A heater 14 for heating an air flow passing through the heating box 18 is incorporated in the heating box 18 together with a radiation prevention plate 19. The radiation prevention plate 19 is provided on the dehumidifying rotor 1 side of the heater 14 and shields the radiant heat of the dehumidifying rotor 1 especially to the purge region 13.

Dehumidifying rotor 1 facing the heating box 18
An exhaust box 20 forming a part of the exhaust air passage 17 is attached to the regeneration region 16 on the other end surface side so that the dehumidifying rotor 1 is sandwiched with the attachment base plate 6. The end surface side of the dehumidifying rotor 1 of the exhaust box 20 is open, and the end surface of the dehumidifying rotor 1 can slide in an airtight state. The exhaust box 20 is connected to one end of an exhaust duct 21 having one end opened to the outside of the room. On the mounting base plate 6 with which one end surface of the dehumidifying rotor 1 is in sliding contact, the circulation air passage 10 of the portion constituted by the passage 3 of the dehumidifying area 7 of the dehumidifying rotor 1
A bypass 22 is formed that bypasses the air blower 12 and causes a part of the air flow from the blower 12 to flow into the air outlet 9 of the circulation air passage 10. The bypass 22 is provided with an opening / closing plate 23 so that it can be opened and closed by an operation from the inside of the room.

As shown in FIG. 5, the above-mentioned dry ventilation device is installed using the space above the ceiling so that the suction port 8 and the air outlet 9 face the ceiling surface of the room such as the bathroom 24. To be The exhaust duct 21 is arranged so that one end thereof is exposed to the outside and opens. When making the installed room a dry atmosphere, the blower 12, the dehumidifying rotor 1, and the heater 14 are all operated. The air in the room is sucked into the circulation air passage 10 by the operation of the blower 12. Most of the sucked air is rotated by a blower 12 in the dehumidifying region 7 of the dehumidifying rotor 1.
The air is again blown out into the room from the air outlet 9 through the passage 3. A part of the sucked air is sent to the heating box 18 through the passage 3 of the purge area 13 of the dehumidifying rotor 1 rotated by the blower 12, and the heater 14 in the heating box 18 is supplied.
The passage 3 of the regeneration region 16 of the dehumidifying rotor 1 that is heated by
To the outside through the exhaust box 20 and to the outside through the exhaust duct 21. When the bypass 22 is opened by the opening / closing plate 23, a part of the sucked air passes through the bypass 22 of the mounting base plate 6 and is blown out from the outlet 9 without passing through the passage 3 of the dehumidifying rotor 1. .

The dehumidifying rotor 1 is rotating at a low speed, and the passages 3 in the dehumidifying area 7 sequentially move to the regeneration area 16, and the passages 3 in the regenerating area 16 are sequentially purged in the purging area 13.
And the passage 3 in the purge area 13 moves to the dehumidifying area 7 for continuous operation. The high-temperature exhaust gas flow heated by the heater 14 flows into the passage 3 of the regeneration region 16 which constitutes a part of the exhaust air passage 17, thereby continuously dehumidifying the dehumidification rotor 1 of the part. The passage 3 of the dehumidifying rotor 1 that has been dehumidified by passing through the regeneration region 16 and has been given the dehumidifying ability is heated to a high temperature by the heat of the heater 14, but in the next purging region 13, the blower 1
The air stream from 2 is blown in and cooled. The passage 3 of the dehumidifying rotor 1 that has passed through the purging region 13 and has been cooled is sequentially transferred to the dehumidifying region 7 and continuously absorbs moisture from the air flow passing through the passage 3. The air flow that has been absorbed and has become a dry atmosphere is mixed with the air flow from the bypass 22 and blown out into the room through the air outlet 9 to make the room a dry atmosphere. The moisture of the dehumidifying rotor 1 that has absorbed moisture in the dehumidifying region 7 is again dehumidified and regenerated in the regenerating region 16 to have the dehumidifying ability.

The moisture absorption capacity of the dehumidification rotor 1 in the dehumidification region 7 is affected by temperature, and the lower the temperature, the higher the moisture absorption capacity. In the dry ventilator of the first embodiment, the dehumidifying rotor 1 heated in the regeneration region 16 and having the surface temperature increased, is
Since the air is cooled by the passage of the air flow at room temperature in 3 to reach the dehumidifying area 7, the dehumidifying ability in the dehumidifying area 7 is maintained high. At the same time, the radiant heat from the heater 14 to the purge area 13 is shielded by the radiation prevention plate 19, so that the temperature of the dehumidifying area 7 is kept low and the moisture absorbing ability of the dehumidifying rotor 1 can be efficiently drawn out.

The radiation prevention plate 19 also prevents the surface temperature of the regeneration area 16 of the dehumidifying rotor 1 from rising excessively. If the surface temperature of the dehumidifying rotor 1 in the regeneration region 16 rises too much due to radiant heat, the dehumidifying rotor 1 will have uneven temperature, which will shorten the life of the dehumidifying rotor 1 and increase the amount of exhaust heat, resulting in poor efficiency. Therefore, such inconvenience can be eliminated. In order to release the moisture from the dehumidifying rotor 1 in the regeneration area 16, it is necessary to heat the exhaust gas flow by the heater 14, but the passage 3 in the purge area 13 is heated in the previous regeneration area 16,
Since the exhaust flow that has passed through the passage 3 in the purge region 13 is preheated by receiving heat, the heating input by the heater 14 can be reduced accordingly and the energy efficiency is improved. By efficiently using the dehumidifying rotor 1 in this way, the amount of circulating air and the amount of exhaust air that form a dry atmosphere can be reduced. Therefore, the total air volume is small, and the blower 12 can be downsized.

When the articles to be dried 25 such as clothes are hung in the bathroom 24 to dry them, the drying time becomes shorter when the air in a dry atmosphere having a higher degree of drying is brought into contact with the articles to be dried 25. However, it is also an important factor to shorten the drying time to quickly remove the moisture taken from the material to be dried 25 by separating it from the material to be dried 25. In this drying ventilation device, the moisture stripped off is continuously discharged to the outdoors by a small amount of exhaust air during the drying operation, and moreover,
By opening the bypass 22, the amount of air blown into the room from the outlet 9 can be increased by the air flow flowing through the bypass 22, so that the flow velocity of the air flow flowing on the surface of the material to be dried 25 is increased. Therefore, the water is quickly separated from the material to be dried 25, and the drying time is shortened as shown in FIG.

By stopping the dehumidifying rotor 1 and the heater 14 and operating only the blower 12, a part of the room can be ventilated while circulating the air. That is, the exhaust air passage 17
After that, a small amount of air is ventilated with an appropriate amount of air, and at the same time, the air in the room can be circulated by the circulation air passage 10 and the bypass 22. In the bathroom 24 and the like after taking a bath, the ventilation operation can dry the wall surface, floor, and the like, and it is possible to suppress the generation of mold and the like. If the amount of ventilation air is insufficient in the ventilation by the exhaust air passage 17 that is originally set to be small, the blower 12 may be configured to have a variable speed and the rotation speed of the blower 12 may be increased. However, since ventilation is performed through the passage 3 of the dehumidifying rotor 1, there is a pressure loss due to the dehumidifying rotor 1 and the air volume is reduced accordingly, so that it cannot be said that the ventilation is efficient.

Embodiment 2 of the Invention In the dry ventilation device of the first embodiment described above, the ventilation is a small amount of ventilation,
Since the diameter of the exhaust duct 21 that is opened to the outside may be small, the workability of the exhaust duct 21 is good, but as mentioned above, it is not necessarily suitable for ventilation of a large air volume. In the second embodiment, the dry ventilation device shown in the first embodiment is devised so as to easily carry out ventilation with a large air volume, and the configuration other than this is shown in the first embodiment. It is the same as the one. Therefore, Embodiment 1
The same reference numerals are used for the same parts as those of the dry ventilator and the description thereof is omitted.

The dry ventilation device of the second embodiment is shown in FIG.
As shown in FIG. 8, the exhaust box 20 is provided with an exhaust bypass 26 that communicates with the circulation air passage 10 on the upstream side of the dehumidification rotor 1. The exhaust bypass 26 is a path relating to exhaust that bypasses a portion of the exhaust air passage 17 formed by the passage 3 of the dehumidifying rotor 1 and a portion formed by the heating box 18. The exhaust bypass 26 is provided with an opening / closing damper 27 for opening / closing the exhaust bypass 26. The exhaust duct 21 connected to the exhaust box 20 has a larger diameter than that of the first embodiment so as to correspond to the processing air volume. The rest of the configuration is the same as that of the first embodiment, and therefore its explanation is omitted.

In this drying ventilation device, the exhaust bypass 2
In the state where 6 is closed by the opening / closing damper 27,
Performs exactly the same function as the dry ventilation device shown in. In case of need of ventilation operation with large air volume, bypass 22
Is closed, the operation of the dehumidifying rotor 1 and the heater 14 is stopped, the exhaust bypass 26 is opened by the opening / closing damper 27, and the blower 12 is operated. That is, although a part of the air flow blown from the blower 12 passes through the passage 3 of the dehumidifying rotor 1 having a large pressure loss and goes to the air outlet 9, most of the air flow flows to the exhaust bypass 26 having a small pressure loss and remains as it is from the exhaust box 20. It will be discharged to the outside through the exhaust duct 21. Therefore, quick ventilation with a large air volume can be realized with a simple configuration without employing a complicated configuration such as increasing the rotation speed of the blower 12. The other functions and advantages are the same as those of the first embodiment, and the description thereof will be omitted.

Third Embodiment of the Invention The dry ventilation device of the third embodiment is obtained by adding a heating function to the dry ventilation device shown in the first and second embodiments.
The first and second embodiments are basically the same except for the configuration related to the heating function.
Is the same as Therefore, the same parts as those of the dry ventilation device of the first and second embodiments are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIGS. 9 and 10, this third embodiment
The dry ventilation device is provided with a heater 28 for heating, which heats the air flow flowing through the part in the vicinity of the outlet 9 of the circulation air passage 10. The exhaust box 20 is provided with the exhaust bypass 26 as shown in the second embodiment. However,
The open / close damper 27 for opening / closing the exhaust bypass 26 is different from that of the second embodiment in that the exhaust path in the exhaust box 20 can be fully closed at the neutral position A. The rest of the configuration is the same as that of the second embodiment, and therefore its explanation is omitted.

The dry ventilation device of the third embodiment can perform the drying operation and the ventilation operation as in the first and second embodiments, and can also perform the heating operation. During the heating operation, the bypass 22 is opened, the dehumidifying rotor 1 and the heater 14 are stopped, and the blower 12 and the heating heater 28 are operated. The opening / closing damper 27 for the exhaust bypass 26 is set to the neutral position A and the exhaust air passage 17 is closed. That is, all the air in the room sucked by the blower 12 passes through the circulation air passage 10 and the bypass 22 and is blown out from the outlet 9.
Is blown into the room again. The airflow blown out from the air outlet 9 is heated by the heater 28 for heating to become warm air, which creates a heating atmosphere in the room. Since the exhaust air passage 17 is fully closed by the opening / closing damper 27, heat from the heater 28 for heating is prevented from being released to the outside through the exhaust air passage 17. The heater 28 for heating may be composed of an infrared heater, but even in this case, it is necessary to blow air by the blower 12 in order to prevent overheating of the infrared heater portion. In addition, although the drawing shows the heating heater 28 applied to the second embodiment, it can be applied to the one shown in the first embodiment in exactly the same manner. Of course, the heating heater 28 is stopped during the dry operation or the ventilation operation. The other functions and advantages are the same as those of the first and second embodiments, and therefore their explanations are omitted.

Fourth Embodiment of the Invention The dry ventilation device of the fourth embodiment is the same as the dry ventilation device shown in the above-described first and second embodiments with a heating function, and is basically the same as the dry ventilation device except for the configuration related to the heating function. It is the same as that of the forms 1 and 2. Therefore, the first and second embodiments
The same reference numerals are used for the same parts as those of the dry ventilator and the description thereof is omitted.

In the third embodiment, the heating function is performed by the heating heater 28 dedicated to heating, but in the fourth embodiment, the heater 14 provided in the heating box 18 is used.
Is configured to perform the heating function. That is, FIG.
As shown in FIGS. 1 and 12, the heating box 18 has a circulation air passage 1
A communication path 29 communicating with the outlet 9 is provided on the downstream side of the dehumidification rotor 1 of 0. The connecting passage 29 is provided with an opening / closing damper 30 that opens and closes the connecting portion on the side of the circulating air passage 10 and closes and opens the exhaust air passage 17 through the passage 3 of the dehumidifying rotor 1. The rest of the configuration is the same as that of the first and second embodiments, and the description thereof will be omitted.

In the drying / ventilating device of the fourth embodiment, the opening / closing damper 30 closes the connecting passage 29 of the heating box 18 and the passage 3 of the dehumidifying rotor 1 is opened to dry the same as in the first and second embodiments. Can perform operation and ventilation operation. During the heating operation, the bypass 22 is closed, the communication path 29 of the heating box 18 is opened by the opening / closing damper 30, and the path 3 of the dehumidifying rotor 1 is closed. At this time, the dehumidifying rotor 1 is stopped and the heater 14 and the blower 12 are operated. The air flow blown from the blower 12 is the dehumidification rotor 1
Through the passage 3 to the circulation air passage 10 and is blown out from the air outlet 9 into the room, but a part of the air flows into the heating box 18 through the passage 3 that constitutes the exhaust air passage 17 of the dehumidifying rotor 1 and is heated by the heater 14. The temperature is raised and flows into the circulation air passage 10 from the communication passage 29, is mixed with the air flow of the circulation air passage 10 and warms the air blown out from the air outlet 9. This makes it possible to create a heating atmosphere in the room without providing the dedicated heating heater 28.

In the above-described structure, the air involved in heating flows into the heating box 18 through the passage 3 in the purge area 13 of the dehumidifying rotor 1 and is not so large in quantity. In order to increase the amount of air involved in heating, the configuration of the exhaust box 20 described in the third embodiment may be adopted, and the opening / closing damper 30 of the heating box 18 may be configured to have only the opening / closing function of the communication path 29. . When the open / close damper 27 of the exhaust box 20 is set to the neutral position A and the exhaust air passage 17 is closed and the communication path 29 of the heating box 18 is opened, the heating box 18 is opened from both the purge area 13 and the regeneration area 16.
The air can be made to flow in, and the heating function will be improved. Other functions and advantages are the same as those in the first and second embodiments.
Since they are the same as those described above, their explanations are omitted.

Fifth Embodiment of the Invention The dry ventilator of this fifth embodiment has the input adjustment function of the heater 14 added to the dry ventilators shown in the first and second embodiments to improve energy efficiency. The configuration is basically the same as that of the first and second embodiments, except for the configuration related to the input adjustment function of the heater 14. Therefore, the same parts as those of the dry ventilation device of the first and second embodiments are designated by the same reference numerals, and the description thereof will be omitted.

The drying and ventilating apparatus according to the fifth embodiment is shown in FIG.
As shown in FIG. 3, the regeneration area 1 in the exhaust box 20
A humidity sensor 31 is provided near the exit of the passage 3 of 6, and the detection output of the humidity sensor 31 is input to the controller 32, and the input to the heater 14 is adjusted by the controller 32. The controller 32 narrows the input to the heater 14 when the detection output of the humidity sensor 31 becomes a predetermined value or less. That is, the amount of water absorbed by the dehumidifying rotor 1 gradually decreases as the dry state progresses in the drying operation. Therefore, the amount of moisture released in the regeneration area 16 also gradually decreases. By detecting the amount of moisture released by the humidity sensor 31, the dry state can be determined. When the dry state has progressed to a predetermined state, the energy efficiency can be improved by narrowing the input of the heater 14.

The humidity sensor 31 described above is replaced by a temperature sensor 33.
The same function can be achieved by changing to. That is, as the dry state progresses, the amount of moisture released in the regeneration area 16 decreases,
The temperature of the exhaust flow leaving the passage 3 in the regeneration zone 16 rises.
By detecting the temperature of this exhaust flow with the temperature sensor 33, the dry state can be determined. When the dry state progresses to a predetermined state and the detection output of the temperature sensor 33 becomes a predetermined value or more, the energy efficiency can be improved by reducing the input of the heater 14 by the controller 32.

Sixth Embodiment of the Invention The dry ventilator of this sixth embodiment is configured to be attached to the indoor side wall surface of the chamber to which the dry ventilator described in the first to fifth embodiments is applied, and other configurations are the same as those described above. It is the same as that shown in the embodiment. Therefore, the same parts as those of the dry ventilation device of each embodiment are designated by the same reference numerals, and the description thereof will be omitted.
