Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a dehumidifying dryer capable of efficiently recovering water evaporated from a material to be dried as drain water and using it without an exhaust duct structure.

[0002]

2. Description of the Related Art Air whose temperature has been increased by a heating source and whose relative humidity has been reduced is sprayed on laundry to be dried to remove moisture from the object to be dried, and the treated air having increased humidity is exhausted. 2. Description of the Related Art Dryers that discharge air to outside of a room through a duct are known.
In many homes, such an exhaust duct leading to the outside of the room is not provided in most cases, and some dryers directly discharge humid air into the room.

[0003] As described above, if the air after the treatment after removing moisture from the material to be dried is released indoors, the environment becomes extremely bad.
There is a dryer that is provided with a heat exchanger for high-humidity high-temperature air and exchanges heat between low-temperature indoor air and high-humidity high-temperature air. In this dryer, the air after the treatment, which has become high in humidity, is cooled by a heat exchanger to partially liquefy water, and a part of water vapor in air released indoors is removed as drain water.

[0004]

In a conventional dryer, an electric heater or a gas combustor is used as a heating source for producing air at a high temperature. There is a slight anxiety. In addition, high-temperature and high-humidity treated air is discharged outside using an exhaust duct.However, in many homes there is no wall hole for installing an exhaust duct that connects to the outside of the room. And the construction of a new hole in the wall is required, so that the most preferable method of discharging to the outside of the room has not been widely used.

[0005] When high-temperature and high-humidity air cannot be discharged outside the room, the air is discharged directly into the room. However, high-humidity air having a high temperature and a relative humidity of nearly 100% is discharged into the room. As a result, the indoor environment is deteriorated, so that the use of such indoor-installed dryers is restricted, and laundry is often dried on a veranda or the like.

[0006] Further, the place where the dryer is installed is indoors, such as near a bathroom or a washroom. However, such a place is generally narrow and there is a problem of deterioration of the indoor environment. Further, in such a place, there is no place for easily installing the exhaust duct, and the installation of the exhaust duct requires a large-scale remodeling work, which requires a large expense. Furthermore, in these places, since water is used, it tends to be always in a humid state, the environment is not always good, and the room is always a place that needs to be dried.

In order to avoid such a problem, there is a dryer for exchanging heat between low-temperature indoor air and high-temperature treated air having an increased humidity. However, the dryer can be liquefied by heat exchange with indoor air. The amount of water vapor is negligible, and the humidity does not drop sufficiently even after dehumidification by the heat exchanger, and although a part of the water vapor is removed, the air in a high-humidity state where the temperature is still high and the relative humidity is close to 100% is released indoors. As a result, there is no doubt that the indoor environment is deteriorated, and a solution has been desired.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and comprises a compressor 1 for pressurizing a gaseous refrigerant, and a first compressor 1 for cooling and liquefying a compressed high-temperature and high-pressure refrigerant.
A heat exchanger 2 and a second heat exchanger 3 for vaporizing a liquefied refrigerant sent through a capillary are provided. The refrigerant vaporized by the second heat exchanger 3 is sent to the compressor 1, and a refrigeration circuit is formed by the circulating refrigerant. A blower fan 4 for forming an airflow passing through the first heat exchanger 2 and the second heat exchanger 3
A drain pan 5 disposed below the second heat exchanger 3 for collecting liquefied water; and a drying drum 6 communicating with the second heat exchanger 3. The fan 4 for blowing air blows the second heat from the drum 6 for drying. An air flow is formed that circulates again through the exchanger 3 and the first heat exchanger 2 to the drying drum 6, and the moisture of the material to be dried vaporized by the drying drum 6 is liquefied by the second heat exchanger 3 and collected in the drain pan 5. Since the air flow circulating through the drying drum 6 is a closed system, the drying can be performed very efficiently.

Further, the drying drum 6, the second heat exchanger 3, and the first heat exchanger 2 are arranged in series, and the electric motor 7 for driving the drying drum 6 returns from the first heat exchanger 2 to the drying drum 6. An air guide duct 8 for circulating air flow is provided, and an electric motor 7 and a compressor 1 are arranged in the air guide duct 8, and the air dehumidified by the second heat exchanger 3 is introduced into the first heat exchanger 2 by the air guide. Heated by the compressor 1 and the electric motor 7 in the duct 8, the temperature is further raised and returned to the drying drum 6, so that the object to be dried is dried quickly.

A drying drum 6, a second heat exchanger 3, and a first heat exchanger 2 are arranged in series, and a wind guide duct 8 for circulating air flow returning from the first heat exchanger 2 to the drying drum 6. The air duct 9 is provided with an air inlet 9 and an air outlet 10 so that room air can be taken into the drying drum 6. The dryer takes in surrounding air. Since the air after dehumidification is discharged, even if the dryer is installed in a small room such as a bathroom or a washroom, the environment does not become a high-temperature and high-humidity environment.

Further, the drying drum 6 from the first heat exchanger 2
Air duct 9 for a circulating air flow returning to the air duct, an air inlet 9 and an air outlet 10 opened at the portion of the air duct 8,
A rotation stopping means 11 for arbitrarily switching the rotation / stop of the drying drum 6, the rotation stopping means 11 opening the air suction port 9 and the air discharging port 10 when the rotation of the drying drum 6 is stopped; Is stopped and only the dehumidifying function is operated, so that the operation as a dehumidifier can be performed without putting the material to be dried in the drying drum 6.

Further, a drain water outlet 5a of the drain pan 5 is provided.
The drain tank 12 or the drain hose 13 can be selectively installed in the tank, so the drain tank 12 is used when the amount of dehumidification is small or when moving, and the drain hose 13 is attached when the stationary dehumidifier is installed, so that a large amount of material to be dried is provided. It became possible to correspond to.

[0013]

The humidified air passing through the drying drum 6 containing the material to be dried enters the second heat exchanger 3, and the second heat exchanger 3 is cooled by the refrigerant. It is liquefied to drain water and collected in the drain pan 5. The air from which the moisture has been removed enters the first heat exchanger 2 and cools and liquefies the high-pressure refrigerant in the compressor 1, and the circulating air rises in temperature due to latent heat of condensation. The dehumidified and high-temperature air is returned to the drying drum 6 by the action of the blower fan 4, and thus the drying drum 6 passes through the second heat exchanger 3 and the first heat exchanger 2 again. A path circulating to 6 is created.

The air humidified by drying the material to be dried on the drying drum 6 is dehumidified by the adjacent second heat exchanger 3 to become dry air. Therefore, if the air is returned to the drying drum 6, the material to be dried can be efficiently dried. For this reason, the air used for drying can be operated in a closed system with almost no leakage to the outside.

A first heat exchanger 2 for cooling and liquefying the refrigerant, a second heat exchanger 3 for evaporating the liquefied refrigerant sent through the capillary, and a first heat exchanger 2 A refrigeration circuit is constituted by the compressor 1 fed to the second heat exchanger 3 in which the refrigerant evaporates.
Is cooled down, the moisture in the circulating air humidified by the drying drum 6 is efficiently dehumidified, and the circulating air is cooled down on the surface of the second heat exchanger 3.

Since the cooled air is sent to the first heat exchanger 2, the first heat exchanger 2 to which the pressurized high-temperature refrigerant is sent is efficiently cooled by the cooled air. As a result, a high-temperature and high-pressure gaseous refrigerant is liquefied, and a system having a very high efficiency of a refrigeration circuit using the refrigerant can be assembled.

[0017]

The first heat exchanger 2 functions as a condenser, and the second heat exchanger 3 functions as an evaporator. Then, the refrigerant vaporized in the second heat exchanger 3 is returned to the compressor 1 and is pressurized again.

As described above, the refrigerant circulates through the compressor 1, the first heat exchanger 2, and the second heat exchanger 3 to form a refrigeration circuit. The first heat exchanger 2 is pressurized by the compressor 1 and has a high temperature. The high-temperature refrigerant has a high temperature due to heat radiation of the high-temperature heat, while the second heat exchanger 3 is cooled by the heat absorbed when the refrigerant liquefied in the first heat exchanger 2 evaporates and has a low temperature. .

Reference numeral 14 denotes a cabinet body of the dehumidifying dryer, and 1
4a is a rear cabinet composed of side, back and top panels of the cabinet 14, 14b is a front panel which constitutes a front panel of the cabinet 14, and 14c is a cabinet 14
Is a partition plate for dividing the inside of the rear cabinet 14a into an upper chamber and a lower chamber. The cabinet 14 forms a substantially box body, and the compressor 1 is a cabinet 1
4 is attached to the base 14c of the first heat exchanger 2
And the third heat exchanger 3 are disposed in an upper chamber partitioned by a partition plate 14d.

Reference numeral 6 denotes a cylindrical drying drum connected to the second heat exchanger 3 and disposed in an upper chamber above the partition plate 14d of the cabinet 14. Reference numeral 6a denotes an opening / closing lid provided on an open front surface of the drying drum 6. Reference numeral 15 denotes a shaft serving as a rotation center of the drying drum 6. By opening an opening / closing lid 6a of the drying drum 6 provided on the front panel 14b, an object to be dried can be inserted into the inside of the drying drum 6. . A bearing portion is formed at the center of the rear surface of the drying drum 6 and is supported by the shaft 15. The drying drum 6 is rotatably mounted on the shaft 15.

4 is a blower fan for creating an air flow passing through the drying drum 6, the second heat exchanger 3, and the first heat exchanger 2.
Reference numeral 7 denotes an electric motor for simultaneously driving the blower fan 4 and the drying drum 6. The blower fan 4 is disposed at the back of the first heat exchanger 2, and the shaft 15 supports the blower fan 4 and the drying drum 6. ing. Reference numeral 4a denotes a fan pulley attached to the rotating shaft of the electric motor 7, and the blower fan 4 is driven by a fan pulley 4a via a belt to blow air necessary for heat exchange.

Reference numeral 6b denotes a drum fixing plate for supporting a part of the front side of the drying drum 6 which is open. Reference numeral 4b denotes a drum pulley attached to a rotating shaft of an electric motor 7. The other end is supported by a drum fixing plate 6b, and is driven via a belt by a drum pulley 4b rotated by an electric motor 7.

Reference numeral 5 denotes a drain pan disposed below the second heat exchanger 3; 8 denotes a wind guide duct for returning an air flow from the first heat exchanger 2 to the front side of the drying drum 6; The air that has passed through the drying drum 6 and dried the material to be dried and became humid first is sent to the second heat exchanger 3 to be dehumidified, and the liquefied water accumulates in the drain pan 5 below the second heat exchanger 3.

The air from which moisture has been removed by dehumidification in the second heat exchanger 3 enters the first heat exchanger 2, where it becomes high pressure in the compressor 1 to cool and liquefy the refrigerant. As a result, the air becomes hot due to the latent heat of condensation of the refrigerant. This air is sent again to the drying drum 6 via the air duct 8 to form a circulating air flow. At this time, when the electric motor 7 is driven, the drying drum 6 is rotated, and the object to be dried in the drying drum 6 is rotated and agitated, so that the whole is uniformly and efficiently dried.

That is, the air flow generated by the blower fan 4 driven by the electric motor 7 removes moisture from the material to be dried in the rotating drying drum 6 and becomes a humidified air flow. It flows to the second heat exchanger 3. Then, in the cooled second heat exchanger 3, the moisture contained in the air flow is drained on the fin surface and becomes low temperature in a state where the absolute humidity is reduced, and the low temperature air is cooled to the next heated first heat exchanger 3. 2, heat exchange in the direction of heating the low-temperature air dehumidified by the second heat exchanger 3 is performed. Further, the first heat exchanger 2
The temperature of the air flow that has risen and the relative humidity is very low passes through the air guide duct 8 by the blower fan 4 and returns to the first drying drum 6.

At this time, the gaseous refrigerant which has become high temperature and high pressure in the compressor 1 is heating the first heat exchanger 2, and the high temperature first heat exchanger 2 is cooled by the second heat exchanger 3. The humidified, low-temperature air flow effectively acts, and the refrigerant in the first heat exchanger 2 is efficiently removed of heat and liquefied. In the second heat exchanger 3 to which the refrigerant is sent via the capillary, the liquefied refrigerant is vaporized and cools the second heat exchanger 3 more strongly.

As described above, since the present invention has created a circulation system for the drying air, it is not necessary to discharge the dried air to the outside during the drying, and the dryer is provided. It no longer pollutes the surrounding environment. In addition, there is no need for a duct work for discharging the high-temperature and high-humidity air to the outside of the room, which has conventionally been required for installing this type of dryer, and the dryer can be easily attached and used. Furthermore, a favorable environment can be maintained even if the dryer is installed indoors without using an exhaust duct as in the related art.

This system constitutes a closed system which returns from the first heat exchanger 2 to the drying drum 6 via the fan 4 for blowing air, and can realize a system which is more effective than ever as a dryer. The embodiment shown in the figure is a system in which this air flow is partially changed, and the cabinet 1
The drying drum 6, the second heat exchanger 3, the first heat exchanger 2, and the blower fan 4 are arranged in series above the partition 14d of the cabinet 4 and compressed in the lower chamber below the partition 14d of the cabinet 14. The motor 1 for driving the air blower 4 and the fan 1 is arranged.

A flow path from the first heat exchanger 2 to the lower chamber via the blower fan 4 is formed, and a flow path from the front of the lower chamber to the inside of the cylindrical drying drum 6 is formed. Thereby, the lower chamber can function as the air guide duct 8.

Since the electric motor 7 for driving the blower fan 4 and the compressor 1 are arranged in the air guide duct 8 according to the embodiment of the present invention, the air sent from the blower fan 4 is compressed by the compressor 1 and the compressor 1. A closed system that returns to the drying drum 6 via the electric motor 7 can be configured. The drying drum 6, the second heat exchanger 3, the first heat exchanger 2, the blower fan 4, the compressor 1, the electric motor 7, and the drying drum 6 It is a system to return to. For this reason, the amount of heat generated by the compressor 1 and the electric motor 7 serves to increase the temperature of the drying air, and the drying drum 6 can more efficiently dehumidify the material to be dried.

As described above, the air flow is dehumidified by the second heat exchanger 3 and is heated by the kinetic energy of the refrigerant from the gas to the liquid in the first heat exchanger 2, so that the air flow having a very low relative humidity is obtained. At the same time, due to the effect of heat generated from the electric motor 7 and the compressor 1 in the air guide duct 8, a very effective dry state can be created by maintaining a higher temperature than room air.

As described above, the dryer using the closed system has excellent characteristics that do not make the environment outside the equipment humid environment, but the internal temperature rise can be avoided by the energy consumed in the cabinet 14. It is not possible to avoid a rise in the temperature of the circulating air in a closed system during long-time continuous operation. In particular, when the heat generated from the compressor 1 and the electric motor 7 is large, the object to be dried can be efficiently dried. However, when the operation time is slightly increased, the heat of the compressor 1 and the electric motor 7 becomes larger than the dehumidifying calories, and the circulated air is reduced. It gradually becomes hot,
If the heat radiation cannot keep up, it is conceivable that the object to be dried and the interior equipment will be adversely affected.

Another embodiment provides a system which takes this point into consideration. Reference numeral 9 denotes an air suction port provided to face the suction portion of the drying drum 6 of the air guide duct 8, and reference numeral 10 denotes a wind guide duct 8. An air outlet 16 is provided so as to communicate with the first heat exchanger 2, and a damper 16 opens and closes the air inlet 9 and the air outlet 10. The damper 16 in the embodiment is an air inlet 9 and an air outlet 10. In the raised position, the opening of the damper 16 is closed by the air intake port 9.
The opening of the damper 16 is open when the damper 16 is in the lowered position because the opening of the damper 16 matches the air inlet 9 and the air outlet 10.

The normal operation of the dryer is started at the air inlet 9.
The air outlet 10 is used in a closed state by the damper 16, and when the temperature of the circulating air flow rises, the damper 16 is used as an open circuit and the air inlet 9 and the air outlet 10 are opened. Even with an air circulation system closed by this structure, take in the air in the room where the dryer is placed so that the temperature of the air flow does not increase,
By discharging part of the dehumidified high-temperature air coming out of the first heat exchanger 2 into the room, the user could arbitrarily adjust the temperature of the circulating air flow.

When the dryer is operated by opening the damper 16 from the beginning, it is possible to dehumidify the air in the room where the dryer is placed while drying the object to be dried. Could have double drying function.
If the degree of opening of the air inlet 9 and the air outlet 10 can be adjusted by the damper 16, a part of the air flow can be used as the circulating air flow, and the indoor dehumidifying function can be performed while leaving the drying function. It is also possible to have.

The function of the dryer has been described above. The air inlet 9 and the air outlet 1 are provided on the front panel 14b.
When 0 is arranged, it is possible not only to dehumidify the room in which the washing machine is placed, but also to function as a dryer as an ordinary indoor dehumidifier.

Numeral 11 denotes rotation control means formed by a clutch mechanism attached to the rotating shaft of the electric motor 7. The electric motor 7 for driving the blowing fan 4 and the drying drum 6 together operates the rotation control means 11. The rotation of the drying drum 6 can be stopped. When the blower fan 4 and the drying drum 6 are driven by different electric motors 5, a mechanism for stopping only the electric motor 5 of the drying drum 6 serves as the rotation control means 11.

Accordingly, the air inlet 9 and the air outlet 10 provided on the front panel 14b of the cabinet 14
When the rotation of the drying drum 6 is stopped by operating the rotation control means 11 and the rotation of the drying drum 6, the room air passes through the second heat exchanger 3 and the first heat exchanger 2 and is guided by the blower fan 4. The air is discharged into the room through an air discharge port 10 provided in the front panel 14b through the wind duct 8.

Further, the room air moistened with moisture is sucked in from the air inlet 9 provided in the front panel 14b, passes through the drying duct 6, and is dehumidified by the second heat exchanger 3, so that it is efficient. The room air was released in the dehumidified state, and the dryer could be used as a powerful dehumidifier even in ordinary rooms.

As described above, in the present invention, the space in which the washing machine is placed can be dehumidified and dried, and it can be moved to another place in the house to be used as a powerful dehumidifier. It also has a great effect of preventing damage to the house and the growth of mold and bacteria due to the high humidity, and has a completely different effect from conventional dryers.

On the other hand, regarding the treatment of drain water condensed in the second heat exchanger 3 during operation of the dehumidifying dryer and collected in the drain pan 5, reference numeral 5a denotes a drain water outlet provided in the drain pan 5, and 12 denotes a drain water outlet. A drain tank located below 5a, 12a is a full detector of the drain tank 12, and the drain water collected in the drain pan 5 by operating the dehumidifying dryer is collected in the drain tank 12 from the drain water discharge port 5a. The fullness detector 12a detects that the drain tank 12 is full and stops the operation of the dehumidifying dryer.

The filled drain tank 12 can be easily removed from the cabinet 14, and the drain water collected in the drain tank 12 can be discarded. By using the drain tank 12 in this manner, a dehumidifying dryer can be easily installed and used even in a place where drainage is difficult.

13 is a drain water outlet 5a of the drain pan 5
When the dehumidifier / dryer is mainly used as a dryer in a washing machine storage area, the drainage water collected in the drain pan 5 is used because the washing machine storage area can easily treat the drain water. It is sufficient that the dehumidifier drier is drained directly by the drain hose 13 for treatment. The drain water cannot be drained properly and the dehumidifier drier does not stop in a short time. Now available.

[0044]

As described above, according to the present invention, since the material to be dried stored in the drying drum 6 is dried, the water is liquefied by the second heat exchanger 3 from the air stream containing a large amount of water. Since the water is collected in the drain pan 5 as drain water, the water contained in the object to be dried can be easily treated. As a result, it could be prevented from being scattered in the room where the dryer was placed.

The air flowing from the second heat exchanger 3 to the first heat exchanger 2 has a low temperature, and since the moisture in the air has been removed, the absolute humidity has been reduced. (1) As the air for cooling the heat exchanger 2 is better than the normal indoor air, the cooling capacity is excellent, and the refrigeration circuit can work efficiently.

Further, since the water contained in the air stream is liquefied in the second heat exchanger 3 and collected in the drain pan 5,
By creating a circulation system in which the air having a reduced relative humidity after passing through the first heat exchanger 2 is directly returned to the drying drum 6 by the blower fan 4, the airflow does not leak into the room where the dryer is placed. Therefore, a humid air flow was released into the room, which is the biggest problem with conventional dryers, to create a bad environment, and indoor pollution due to odor contained in the dry air could be completely eliminated.

Further, conventionally, in order to prevent deterioration of the indoor environment due to the air dried from the material to be dried, the humid air is heat-exchanged with the low-temperature indoor air to partially liquefy and collect the water, or to exhaust the air. Although it is specified that the air is released outside using a duct, heat exchange with indoor air alone is not enough to prevent deterioration of the indoor environment, and it is proper to guide exhaust air to the outside. Although the construction of the exhaust duct was also necessary, there was no place to install the exhaust duct or the place where it could be released outside the room.However, according to the present invention, there is no need to install a heat exchanger with the indoor air or the exhaust duct, and this problem is easily solved. The point could be solved.

If only the Joule heat of the electric heater is used as in a conventional dryer, the available heat cannot perform more than 100% of the input. However, when utilizing the cooling and heating of heat by the refrigerant as in the present invention, the only external input to the system is the electric energy used for the electric motor and the compressor, and many inputs are required for the movement of the refrigerant. It is very easy to extract more than twice the input as the system efficiency of the energy to be used, and the cooling, dehumidification and heating of the air flow by the refrigerant should be taken as a drying system. As a result, the efficiency was dramatically improved.

According to the present invention, a wind guide duct 8 for circulating air from the first heat exchanger 2 to the drying drum 6 is provided.
Since the electric motor 7 for driving the blower fan 4 and the compressor 1 constituting the refrigeration circuit are arranged in the air guide duct 8, the first
Release of heat energy of the refrigerant in the heat exchanger 2,
By radiating heat from the electric motor 7 and the compressor 1, the circulating air flow is heated to create a high-temperature air flow at a very favorable low humidity with respect to the object to be dried, thereby efficiently drying the object. It was possible to remove water from the object, and to obtain a better air flow than the conventional air flow only by heating indoor air.

Further, the first heat exchanger 2 to the drying drum 6
The drying drum 6
An air outlet 9 for venting the air flow from the first heat exchanger 2 into the room and an air discharge port 10 for taking in some of the circulating air from outside the room or discharging some of the circulating air into the room As a result, the temperature of the circulating air flow did not become unnecessarily high, and deterioration of the parts to be dried and the material to be dried in the drying drum 8 due to heat could be prevented.

At this time, since the air discharged into the room from the air discharge port 10 is dehumidified dry air, the environment in the room where the dryer is placed does not deteriorate.

In the above structure, when the motor 7 and the compressor 1 are installed in the air duct 8 in particular, there is an advantage that the object to be dried can be dried quickly. However, when the temperature is too high, both the motor 7 and the compressor 1 have a high temperature. In some cases, the temperature rise of the circulating air flow may occur in a short time such that a trouble in operating the safety device occurs. In the present invention, a large amount of heat radiation from the motor 7 and the compressor 1 is transferred to the air inlet 9 and the air outlet 1.
With the function of 0, the indoor air can be directly taken into the circulating airflow, so that the trouble of temperature rise can be avoided.

An air inlet 9 for taking in room air is provided.
And an air discharge port 10 for discharging the circulating air, and a rotation stopping means 11 for stopping the rotation of the drying drum 8 are provided. Therefore, the air suction port 9 and the air discharge port 10 are opened, and the rotation stopping means 11 is operated. In this state, the indoor air can be returned to the room through the air inlet 9, the second heat exchanger 3, the first heat exchanger 2, the blower fan 4, and the air outlet 10 in a state where the air is dried. In addition, it could be used effectively as a dehumidifier for indoor air, and could be used for a wide range of applications.

Further, a drain water outlet 5a of the drain pan 5
By using the drain tank 12 and the drain hose 13 selectively, the drain tank can be used in a place where there is no drainage equipment. Therefore, the dehumidifier / dryer can be moved to an arbitrary place to be dehumidified and used immediately. It is a thing.
