Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer for drying clothes and the like.

[0002]

2. Description of the Related Art The structure and operation of a conventional example will be described with reference to FIG.

In FIG. 7, 1 is a drying cabinet for drying clothes, 2 is a circulation wind tunnel A provided with an outlet 2a for supplying dry air to the lower part of the drying cabinet 1, and 3 is a blower fan 4 for drying air. A blowing means 5 for circulating and blowing the air is a dehumidifying means composed of a heat exchanger 6 composed of pipes and fins and a cooling fan 7 for air-cooling the heat exchanger 6, and 8 is a cooling air for the heat exchanger 6. A cooling wind tunnel is introduced, 9 is a drain hole for discharging water condensed by the dehumidifying means 5, 10 is a circulating wind tunnel B, and 11 is an air heating means for heating dry air. As described above, the circulation path for supplying the dry air to the drying chamber 1 includes the blower means 3,
It is composed of the dehumidifying means 5 and the circulation wind tunnel 2, and the dry air flows as shown by the arrow а. Reference numeral 12 is an intake port for cooling air provided in the clothes dryer main body 13, and 14 is an exhaust port, and the cooling path flows as indicated by a broken line arrow b. 15 is a drainage tank, 16
Is a hanger pipe for hanging clothes, and 17 is a door sealed by the main body 13 and the packing 18.

Next, the operation will be described. First, clothes (not shown) are hung on a hanger and suspended on the hanger pipe 16. Then, when the air blowing means 3 and the heating means 11 are operated, the dry air flows through the circulation path as indicated by the arrow а, is heated, and is sent into the drying chamber 1 through the outlet 2a. On the other hand, since the cooling fan 7 is also operated at the same time, the cooling air flows through the cooling path as indicated by the broken line arrow b. The dry air hits the clothes and evaporates moisture from the clothes and carries them away. Then, the moist dry air is dehumidified by the dehumidifying means 5 in the circulation path, heated again by the heating means 11 and sent to the drying cabinet 1.
This is repeated and the clothes dry. The water dehumidified by the dehumidifying means 5 is discharged from the drain hole 9 and the drain tank 1
Collect in 5.

[0005]

However, in the above-mentioned conventional structure, the contact between the clothes suspended on the hanger and the dry air in an almost stationary state is not efficient.
The reason is that the dry air that has flowed into the drying chamber 1 flows through a place where the resistance of the hanging clothes is small, and thus it is difficult to contact the place where the clothes overlap. Further, since the dry air flows in from the lower side of the drying chamber 1 through the outlet 2a and rises, the clothes near the outlet 2a are more likely to be dried than the portion located above, and uneven drying occurs. Since the dry air used for drying passes only through such an easy passage, it flows into the dehumidifying means 5 as air in a state in which it can still sufficiently retain the moisture from the clothes even at the stage of flowing out from the drying cabinet 1. To do. Even if the dry air is cooled by the dehumidifying means 5, a part of the amount of heat radiation is spent to bring the temperature close to the temperature at which dew condensation occurs as water, so that the dehumidifying efficiency cannot be effectively reduced. The above-mentioned state is further increased as the clothes dry. As a result, the drying time was longer than necessary.

Further, in this type of dryer, the circulation path for supplying the dry air is constituted by a blowing means having a blowing fan, a dehumidifying means consisting of a heat exchanger, and a plurality of circulating wind tunnels. Further, since the cooling path for blowing the cooling air to the dehumidifying means is composed of the blowing means having the blowing fan, the dehumidifying means including the heat exchanger, and the plurality of cooling wind tunnels, the structure is complicated and the number of parts is large and expensive. It was something.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an inexpensive clothes dryer which enhances the dehumidification efficiency of dry air and shortens the drying time.

[0008]

In order to achieve this object, the first means of the present invention is that one of the dry air flowing out from the blowing means provided in the circulation path of the dry air is bypassed to the dryer. The path and the other constitute a circulation path having a branch flow path with the dehumidifying means.

The second means is such that the outlet of the bypass flow path to the drying cabinet is above the drying cabinet, and the outlet to the drying cabinet via the dehumidifying means is below the drying cabinet. is there.

The third means is that the dehumidifying means provided in the circulation path of the dry air divides the passage constituted by the front plate and the wall surface forming the drying chamber by the corrugated plate, and the circulation passage and the cooling passage. Of the flow path.

A fourth means is that the outer peripheral portion of the corrugated plate is integrally formed of a metal plate or a resin plate having a flat surface portion.

A fifth means is such that the blower means for the circulation path and the cooling path uses one motor as a drive source, the circulation fan is provided in the circulation path, and the motor and the cooling fan are provided downstream of the dehumidifying means in the cooling path. It is a thing.

Finally, the sixth means is that the dehumidifying means provided in the circulation path is an extruded hollow body having an opening at the upper and lower ends and having a plurality of partition walls, and the partition walls are circulated through the circulation path.
The cooling paths are alternately configured.

[0014]

According to the first means, the dry air flowing into the drying chamber is blown out again to the drying chamber after coming into contact with the clothes and before a part of the drying air flows into the dehumidifying unit. The remainder flows into the dehumidifying means, so that the dry air, which can still sufficiently contain water, comes into contact with the clothes again and is effectively used for drying, so that the humidity of the dry air becomes high. Therefore, a part of the dry air having high humidity flows into the dehumidifying means, and when the dehumidifying means cools the circulating air, it is efficiently condensed as water to improve the dehumidifying efficiency. The dry air with reduced water content is heated by the heating means and contacts the clothes in the drying chamber again, so that the drying is accelerated and the drying time is shortened.

According to the second means, since the outlet of the bypass passage for the dry air is provided above the drying cabinet, the clothes positioned above and the dry air are brought into contact with each other again. Due to the reuse of the dry air and the diffusion effect, there is no unevenness in drying and the drying time becomes faster.

According to the third means, the dehumidifying means divides the passage formed by the front plate and the wall surface of the drying chamber by one corrugated plate to form a circulation path for dry air and a cooling path for cooling air. Therefore, the configuration is simple and inexpensive.

According to the fourth means, since the outer peripheral portion of the corrugated plate constitutes a flat surface portion and the flat surface portion and the wall surface forming the drying chamber are attached to each other on a flat surface, the sealing performance is improved. The amount of dehumidification can be increased without leakage of dry air flowing through the dehumidification means.

According to the fifth means, the blowing means for the dry air and the cooling air is driven by one motor, and the motor is provided on the lee side of the dehumidifying means. Therefore, the cooling air sucked from the outside of the dryer main body is used. Is not increased by the heat of the motor. Therefore, since the dry air is efficiently cooled by the dehumidifying means, the dehumidifying efficiency is high.

According to the sixth means, it is a dehumidifying means which is an extrusion-molded hollow body having an opening at both upper and lower ends and having a plurality of partition chambers, and a circulation path and a cooling path are alternately constituted, which is very constitutional. Is simple and cheap.

And an air guide plate configured to communicate with the circulation path 26 of the dehumidifying means 23. Reference numeral 33 is a cooling wind tunnel, and 34 is a motor as a drive source of the blowing means 22 including a cooling fan 35 and a circulation fan. The cooling wind tunnel 33 is configured to communicate with the cooling path 27 of the dehumidifying means 23, and the motor 34 is provided leeward of the dehumidifying means 23. 36 is a cooling wind tunnel provided below the drying chamber 19, 37 is an inlet for cooling air,
Reference numeral 38 is an outlet for cooling air, and 39 is an inlet for dry air provided on the top surface of the drying chamber 19. Drying room 1 as above
The circulation path for supplying the dry air to 9 is composed of an air blower 22, a circulation wind tunnel 21, a dehumidifier 23, a heater cover 29, and a heater 30. It flows to the warehouse 19. On the other hand, the cooling path is composed of the cooling wind tunnel 36, the dehumidifying means 23, the cooling wind tunnel 33, and the cooling fan 35, and flows as indicated by the broken line arrow b. Reference numeral 40 is a drain hole for discharging water condensed by the dehumidifying means 23, 41 is a drainage tank, 42 is a hanger pipe for hanging clothes, and 43 is a door sealed by the main body 20 and a packing 44.

Next, the operation will be described. First, clothes (not shown) are hung on a hanger and suspended on the hanger pipe 42. Then, when the motor 34 and the heating means 30 are energized, the drying air is heated and sent to the circulation path and the inside of the drying cabinet 1 as indicated by arrow а. On the other hand, the cooling air flows through the cooling path as indicated by the broken line arrow b. The dry air hits the clothes and evaporates moisture from the clothes and carries them away. Then, a part of the dry air flowing out of the circulation wind tunnel 21 through the intake port 39 is partially dehumidified by the dehumidifying means 2.
3. The rest flows from above the drying cabinet 19 through the outlet 32a which is a bypass flow path. The dry air flowing into the circulation path 26 of the dehumidifying means 23 is cooled and condensed by the cooling air flowing into the cooling path 27 via the corrugated plate 24. The dry air with reduced water content is heated by the heating means 30 and is sent again from below the drying cabinet 19 through the outlet 31. The water dehumidified by the dehumidifying means 23 is discharged from the drain hole 40 and stored in the drainage tank 41.

According to this structure, firstly, after the dry air flowing into the drying chamber 19 comes into contact with the clothes, a part of the dry air is dehumidifying means 23.
Before it flows into the drying chamber 19 again from the outlet 32a of the bypass passage. The rest flows into the dehumidifying means 23. The humidity of the dry air increases because the dry air, which may still contain sufficient moisture, comes into contact with the clothes again and is effectively used for drying. Therefore, a part of the dry air having considerably higher humidity than in the conventional example flows into the dehumidifying means 23, and when the dry air is cooled by the dehumidifying means 23, it is efficiently condensed as moisture, so that the dehumidifying efficiency becomes high. Further, the dry air with reduced water content is heated by the heating means 30 and is again dried in the drying chamber 19.
Since it comes into contact with the clothes inside, the drying is accelerated and the drying time is shortened.

Second, since the blowout port 32a of the bypass passage for the dry air is provided above the drying cabinet 19, the clothes positioned above and the dry air are brought into contact with each other again.
At the same time, the dry air that has flown in through the air outlet 31 provided below the drying chamber 19 is diffused by the dry air from the air outlet 32a. Therefore, the clothes suspended by the reuse of the dry air and the diffusion effect have no drying unevenness, and the drying time is quick.

Third, the dehumidifying means 23 includes the front plate 25 and the main body 2.
Since 0 and 0 form a dry air circulation path 26 and a cooling air cooling path 27 with a single corrugated plate 24, the conventional example of dry air is replaced with a circulating wind tunnel A2 for guiding the dry air to the lower side of the drying chamber for dehumidification. Since the means 23 is configured, the structure is simple, the number of parts is reduced, and the cost is low.

Fourthly, since the dehumidifying means 23 is a portion where the circulating air and the cooling air come into contact with each other, a sealed structure between both the air is required. In the present embodiment, the corrugated plate 24 has the flat surface portion 24a on the outer peripheral portion thereof, and the flat surface portion 24a has a flat surface attachment structure with the wall surface of the box forming the drying chamber 19, so that the sealing performance is high. As a result, the amount of dehumidification is increased without the leakage of dry air flowing through the circulation path.

Fifth, the blowing means for the dry air and the cooling air is driven by one motor 34, and the motor is the dehumidifying means 2.
It is installed in the lee of 3. Since the cooling air is taken in through the intake port 37, directly passes through the cooling wind tunnel 36, and flows into the cooling path 27 of the dehumidifying means 23, it is not increased by heat generation of the motor. Therefore, the dehumidifying means 23 can efficiently cool the dry air, so that the dehumidifying efficiency is high.

Next, a second embodiment will be described with reference to FIGS. 19 to 22, 29 to 4 in FIG.
No. 4 is the same as that of the first embodiment shown in FIG. Reference numeral 45 denotes a dehumidifying means which is a hollow body which is open at both upper and lower ends and which is integrally extruded from metal or resin having a plurality of partition chambers, and which has circulation paths 45a and cooling paths 45b alternately arranged. Reference numeral 46 is a circulation path 45 of the dehumidifying means 45.
a dry air intake port provided in a, 47 is a cooling path 45
b is an exhaust port provided in b, 48 is an exhaust port for dry air provided in the circulation route 45a, and 49 is an intake port for cooling air provided in the cooling route 45b. The upper opening of the dehumidifying means 45 is closed by an upper lid 50, and the lower opening is closed by a lower lid 51. The intake port 46 communicates with the circulation wind tunnel A21, and the exhaust port 48 communicates with the heater cover 29. The exhaust port 47 communicates with the cooling wind tunnel 33, and the intake port 49 communicates with the cooling wind tunnel 36. As described above, the circulation path for supplying the dry air to the drying chamber 19 is composed of the air blowing means 22, the circulation wind tunnel 21, the circulation path 45a of the dehumidifying means 45, the heater cover 29, and the heating means 30, and is dried as indicated by an arrow а. Air outlets 31 and 3

3 and the cooling fan 35, and flows as indicated by the broken line arrow b.

Next, the operation will be described. The process of drying the clothes is basically the same as that of the first embodiment, and thus detailed description thereof will be omitted. The high-humidity dry air flowing through the circulation path 45a of the dehumidifying means 45 is cooled by the cooling air flowing through the adjacent cooling path 45b to cause dew condensation, and is discharged as water from the drain hole 40 and stored in the drainage tank 41. The dehumidifying means 45 does not require a special dehumidifying means 5 because it constitutes the dehumidifying means 23 in place of the circulating wind tunnel A2 that guides the dry air to the lower side of the drying chamber in the conventional example, so that the structure is simple. In addition, a metal or resin material extruded hollow body having a plurality of partition chambers is cut into a desired length, and the intake port 4
It is completed by processing 6, 49 and the exhaust ports 47, 48. That is, since it is a dehumidifying means in which a circulation path and a cooling path are alternately constituted by one part, the structure is very simple, the number of parts can be reduced, and the cost is low.

[0029]

Further, a part of the dry air having high humidity flows into the dehumidifying means, and the dehumidifying means can efficiently condense it as water, so that the dehumidifying efficiency is high and the drying time is short.

According to the second means, the outlet of the bypass flow path to the drying cabinet is constructed above the drying cabinet, and the outlet to the drying cabinet via the dehumidifying means is constructed below the drying cabinet. The clothes positioned above are dried again. At the same time, due to the diffusion effect, there is no unevenness in drying and the drying time is quick.

According to the third means, the dehumidifying means provided in the circulation path of the dry air divides the passage constituted by the front plate and the wall surface forming the drying chamber by the corrugated plate, and the circulation passage and the cooling passage.
