Abstract

PURPOSE:To provide a clothe drier which feeds a finishing agent through simple constitution and reduces a cost and eliminates a fear of a trouble occurring by providing a support body which has an engaging part engaged with a part to be engaged through energization of an energizing member and supports a finishing agent containing body in a mounting recessed part. CONSTITUTION:A porous substance 39 is formed of a sintered metal, and is disposed in a drying chamber in a manner to be supported to a mounting recessed part 37 in a state to impregnate the porous substance with a liquid finishing agent, e.g. a perfume. A support body 42 provided at a cylindrical side with a line 43 of protrusion in the shape of a hook engaged with a protrusion 38 has the porous substance 39 supported in a mounting recessed part 37. When the starting of a drying motion is indicated by a key board, a microcomputer performs energization to a motor 26 and a heater 17 to start execution of a drying process. A motor 26 rotates a double fan 24 to generate air, which is heated by a heater 17 to produce hot air. The hot air is fed in a drum 10 to dry clothes. During a drying process, the porous substance 39 is also heated by means of hot air, a perfume with which the porous substance 39 is impregnated is leached to a surface. The perfume is vaporized to fill a drying chamber therewith, and is adhered to clothes to provide an excellent smell. This constitution provides a low cost clothe drier which eliminates a fear of a trouble occurring.

In FIGS. 2 to 5, (37) is a cylindrical mounting recess formed in the mounting base (35), (37) is a protrusion as an engaged part formed on the inner surface of the mounting recess, (39) is a porous body as a finished solid body. The mounting recess (37) has a cylindrical shape and is arranged coaxially with the rotation axis of the drum (10), that is, located at the center of the door (5). The porous body (39) is specifically made of sintered metal and can be impregnated with a liquid finishing agent such as perfume, and is supported in the mounting recess (37) as described later in a state impregnated with the finishing agent. and placed in a drying room. (40) is a biasing plate as a biasing member biased in the opening direction of the mounting recess (37) by a spring (old), and (42) is a protrusion (38) as described below.
A support body having a piece-shaped protruding strip (43) on a cylindrical side surface as an engaging part that engages with a porous body (3).

The outer diameter of the biasing plate (40) is approximately equal to the inner diameter of the mounting recess (37), and an inclined surface (40a) is formed on the back side thereof, and a protrusion is provided at the peripheral edge position corresponding to the protrusion (38). (38
) is formed with a slightly smaller notch (40b).

When assembling, first place the spring (41) in the mounting recess (37), and adjust the position of the notch (40b) to the protrusion (3).
Push in the biasing plate (4o) according to the position of 8). At this time, the protrusion (38) is guided by the inclined surface (40a), and the biasing plate (40) itself also bends, so that the biasing plate (4o)
fits into the mounting recess (37) and is prevented from being removed by the protrusion (38) (see FIG. 3(b)).

Then, the porous body (39) impregnated with a finishing agent is fitted inside the support (42), and the indicator (4) of the support (42) is fitted.
2a) on the "remove" side indicator (35a) of the mounting base (35)

) (see Figure 4), push it in against the urging force of Figure 3 (
b) Rotate counterclockwise approximately 60 degrees inside the spring (4).
The protrusion (38) and the protrusion (43) engage with each other due to the biasing force of 1), the support body (42) is attached to the mounting base (35), and the porous body (39) is supported (the fifth (see figure).

FIG. 6 shows a circuit block diagram, and (44) is a microcomputer that controls the motor (26) and heater (17) by referring to the information from the thermistors (32, 33, and 34); (45) is a keyboard for inputting information into the microcomputer.

When the keyboard (45) instructs the start of the drying operation, the microcomputer (44) starts the motor (
26), the heater (17) is energized and the drying process is started. The motor (26) rotates the double-sided fan (24) to generate air, which is heated by the heater (17) to become warm air, which is supplied into the drum (1o) to dry the clothes. The wind that removes moisture from clothing is a hot air outlet (12)
The air is discharged from the air and reaches the double-sided fan (24) again. The double-sided fan (24) exchanges heat with the cooling air sucked in from the cold air inlet (3o) and condenses the moisture taken from the clothes into water droplets. These water droplets are blown around by the rotation of the double-sided fan (24), pass through the circulation pipe (19), and enter the drain hole (1).
8) is discharged from the machine.

During this drying process, the porous body (39) is also heated by the hot air, and as a result, the fragrance impregnated in the porous body (39) leaches onto its surface. The leached fragrance evaporates, fills the drying chamber through the slit (42b) formed in the support (42), and adheres to the clothes, giving them a pleasant fragrance.

Since this embodiment is of a dehumidifying type, the drying air is circulated inside the machine without being discharged to the outside, so it is particularly effective. If you want to change the amount of fragrance that adheres to your clothes,
For example, an adjusting member (not shown) made of a shape memory alloy is provided on the slit (42b), and the slit (42b) is adjusted depending on the temperature.
What you need to do is change the opening area.

The microcombinator (44) is a thermistor (32)
The drying process is executed while performing an operation to determine the end of drying T based on the information from (33). The operation for determining the end of drying is described in detail in Japanese Patent Publications No. 6]-26397, Japanese Patent Application Laid-open No. 163400/1982, and so will not be described here. When drying is completed, the microcomputer (44) stops energizing the motor (26) and heater (17).

As described above, according to the present invention, it is possible to arrange the finishing table body in the drying chamber with a simple configuration, and it is possible to supply the finishing agent to the clothes. Moreover, it is inexpensive and there is no risk of failure.

Further, in the present invention, the protrusion (38) which is the engaged part and the convex ff1 (43) which is the engaging part are arranged so that the support body (42) rotates in the same direction as the rotation direction of the drum (10). When the clothes are being dried, they are connected to each other in the drum (
Even if it collides with the support (42) due to the rotation of the support (42), a force is likely to be applied in the direction in which the protrusion (38) and the protrusion (43) engage with each other, causing the support (42) and the porous body ( 39) will not fall off undesirably.

In this embodiment, the mounting recess (37) is provided on the inner surface of the door (5), but it may also be provided on the surface of the filter device (31), which is another non-rotating surface inside the drying chamber. However, if the porous body (39) is attached to the door (5) as in this embodiment, it is easy to remove the porous body (39), and operations such as replenishing the finishing agent can be performed easily and conveniently.

Further, in this embodiment, the porous body (39) is impregnated with a liquid finishing agent, but instead of the porous body (39), for example, a member configured by consolidating the finishing agent in a solid form is used. may also be used as a finishing object. Alternatively, the width of the slits (4, 2b) may be made large, the porous body (39) is impregnated with an antistatic agent, and the clothing is directly attached to the porous body (39) by rotation of the drum (10) during the drying process.
), the antistatic agent leached onto the surface of the porous body (39) may be attached to the clothing.

(G) Effects of the Invention According to the present invention, the finishing table can be disposed in the drying chamber with a simple configuration, and finishing agent can be supplied to the clothes. Since the configuration is simple, it is inexpensive and there is no risk of failure.

Further, according to the second configuration of the present invention, the engaged portion and the engaging portion are configured to engage with each other when the support rotates in the same direction as the rotational direction of the drum. The body or porous body will not fall undesirably.
