DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a clothes dryer.

(B) Conventional technology As a conventional example, while rotating a horizontal shaft type drum supported in a frame, hot air is introduced into the drum to dry clothes in the drum and to inner wall of the drum. In addition, a clothes dryer provided with a storage portion for storing a mesh bag containing a cloth treatment agent such as an antistatic agent is disclosed in Japanese Patent Publication No. 51-1.
It is disclosed in Japanese Patent Publication No. 9515 (D06M13 / 34).

That is, the cloth treating agent released from the bag adheres to the clothes as the drum rotates, and the cloth treating agent is applied to the clothes.

(C) Problems to be Solved by the Invention In the conventional example, when the temperature inside the drum becomes high, the degree of divergence of the cloth treatment agent becomes high, and when the capacity of the drum is small, the clothes and the bag come into contact with each other. It will be easier.

In such a state, a large amount of the cloth treating agent may adhere to the clothes at one time, which causes stains on the clothes.

The present invention relates to improvement of a clothes dryer, and solves such a problem.

(D) Means for solving the problem While rotating the horizontal shaft type drum supported in the frame,
By introducing hot air into the drum, the clothes in the drum are dried, and the inner wall of the drum is
An accommodating section for accommodating a mesh bag containing a cloth treating agent such as an antistatic agent is attached, and a mesh window is provided in the accommodating section so that the cloth treating agent discharged from the bag does not come into direct contact with clothing. The net-like window is provided and the net-like window is made of resin.

(E) Action Even if a large amount of cloth treatment agent is released from the bag,
Since the curtain of the cloth treating agent is not formed and is adhered to the clothes by the amount of adhering to the net forming the mesh, a large amount of cloth treating agent is not adhered at one time.

Furthermore, since the surface of the net is resin-processed, the amount of cloth treatment agent impregnated by the net itself decreases, so even if the temperature inside the drum rises due to drying, the cloth treatment agent will not adhere too much to the clothes. There is no.

(F) Example 1 is a machine frame of the clothes dryer 2, 3 is a clothes inlet provided in the center of the front surface of the machine frame 1, and 4 is a rear plate fixed to the rear surface of the machine frame 1. , An external air introducing hole 5 is provided in the center, and an outlet 6 is provided in the lower portion. 7 is a door that opens and closes the input port 3, 8 is an annular sheet-metal drum support plate mounted so as to surround the input port 4 in the machine frame 1, 9 is a rear portion of the machine frame 1, and the rear A support plate laterally installed so as to be spaced apart from the face plate 5, 10 is a fan casing fixed to the support plate 9, whereby the inside of the machine frame 1 is divided into a drying chamber 11 and a fan chamber 12. Has been done. Reference numeral 13 denotes a horizontal shaft type drum disposed in the drying chamber 12, which is supported by the drum supporting plate 8 with a felt or the like with a front opening facing the input port 4 and a rear surface. The side is rotatably supported by a shaft 14. 15 ...
Is a dry air outlet provided at the center of the rear surface of the drum 13,
Is a lint filter that covers the outlet 15, 17 is a dry air inlet provided in the lower portion of the drum support plate 8, 18 is provided in the support plate 9, and connects the drying chamber 11 and the fan chamber 12 to each other. The ports and 19 are seal members for reliably sending the air from the dry air outlets 15 to the communication port 18.

Reference numeral 20 denotes a disk-shaped double-sided synthetic resin fan fixed to the shaft 14 in the fan chamber 12, and includes a circulating fan 21 located on the drying chamber 11 side and a cooling located on the rear plate 4 side. The fans 22 ... Are radially formed integrally with the front and back, and a pulley 23 is provided in the central portion on the cooling fan side. Reference numeral 24 denotes a synthetic resin partition plate provided in the fan casing 10 so as to surround the double-sided fan 20, and the double-sided fan is provided in a circular opening in the center of the partition plate 24.
By accommodating 20, the partition plate 24 and the double-sided fan 20 cooperate to partition the inside of the fan chamber 10 into a drying air passage 25 and a cooling air passage 26.

By the way, a concentric group of rotating grooves 27 opening toward the dry air duct 25 is integrally formed on the peripheral edge of the double-sided fan 20, while the cooling air duct 26 is formed on the inner peripheral edge of the partition plate 24. A concentric fixed groove group 28 that opens toward is integrally formed,
The rotary groove group 27 is loosely fitted in the fixed groove group 28 in a non-contact state with each other. That is, the rotary groove group 27 and the fixed groove group 28 form a labyrinth connection.

Reference numeral 29 denotes a drying duct that connects the lower portion of the drying air passage 25 and the drying air inlet 17 ..., In which a heater 30 for heating is arranged. 31 is provided at the bottom of the duct 30, an outlet for discharging the dehumidified water condensed in the duct to the outside of the machine, 32 is a drive motor, and the pulley 23 has a small pulley 3
3, and is connected via a belt 34, and is also connected to the drum 13 via a pulley 35 and a belt 36.

Thus, during drying, the driving force of the drive motor 32 causes the drum 13 to rotate at a low speed and the double-sided fan 20 to rotate at a high speed in one direction, and at the same time, the heater 30 is energized to heat the dry air. It

Thus, the wind generated by the rotation of the circulation fans 21 circulates through the drying air passage 25, the drying duct 29, and the drum 13 to exchange heat with the material to be dried in the drum 13. Also,
By the rotation of the cooling fans 22, external air is introduced into the cooling air passage 26 from the introduction holes 5 and is led out from the outlet 6, and the double-sided fan 20 is cooled at this time. Then, after the heat exchange, the dry air is cooled by contacting the double-sided fan 20, the moisture in the dry air is condensed, flows down in the dry air passage 25, and is discharged from the discharge port 31. During this time, the dry air passage 25 and the cooling air passage 26 are sealed by the labyrinth connection.

Next, the characteristic part of the present invention will be described.

2 to 4, reference numeral 37 denotes a bag body having an antistatic agent 38 filled therein, which is made of cotton or polyester.
Reference numeral 39 is a box-shaped resin case that serves as a storage portion for storing the bag body 37, and a net-shaped window 40 formed of a net 40a is integrally formed at the center of one end face and flanges 41 and 42 are stretched on both side edges. Has been done.

The net 40a is made of nylon and has a resin layer 40b formed on its surface. Specifically, a mixture of urea and formalin is impregnated or Teflon coating is applied to reduce the impregnation of the antistatic agent 38 into the net 40a.

On the other hand, inside the drum 13, on the inner peripheral wall 13a, the flange 4
A first engaging portion 43 for slidingly engaging the first and the second 42 is integrally formed. And the rear surface 13b in the drum 13
Also, a second engaging portion 44 similar to the first engaging portion 43 is formed.

Thus, when the case 39 is attached to the first fastening portion 43 or the second fastening portion, the antistatic agent 38 is released from the bag body 37 during the drying, and the antistatic agent 38 is discharged through the reticulated window 40. It adheres to clothing and gives an antistatic effect to clothing.

At this time, if the mesh diameter 40 of the mesh window 40 is small,
As shown in the figure, since the antistatic agent 38 covers the mesh window 40, a large amount of the antistatic agent 38 at one time may adhere to the clothes and may be partially stained.

Therefore, in this embodiment, the mesh diameter of the reticulated window 40 is set large, specifically 0.4 mm or more, so that the preventive agent 38 does not cover the window net as shown in FIG. 40a, gradually adhering to clothes.

Moreover, in the present invention, since the surface of the net 40a constituting the reticulated window 40 is resin-processed, impregnation of the net 40a with the inhibitor is suppressed as much as possible. No, it does not cause stains on clothing.

(G) Effect of the Invention Since the surface of the net is processed with a resin, impregnation with a cloth treating agent such as an antistatic agent is impaired, so that the chemical agent does not adhere too much to the clothes and cause stains.

By processing the surface of the net with resin, the net itself becomes elastic, making insert molding easier.

By processing the net surface with resin, small irregularities are created on the surface. This prevents the cloth treatment agent from oozing out little by little and adhering to one place of the clothes, so that no stain occurs.
