Description

DETAILED DESCRIPTION OF THE INVENTION In the present invention, a horizontal drum is rotatably provided in the machine frame, and the outside air sucked through the outside air intake 1 provided in the machine frame is sent to a heating device and heated, and then heated. Regarding clothes dryers that dry clothes by supplying heated air with Even when the diameter of the drum is increased by reducing the diameter of the drum, excellent drying efficiency can be obtained.

In recent years, clothes dryers are often used in combination with washing machines and placed above the washing machine, or placed along indoor walls, etc. From the point of view of harmonization, it has become desirable to reduce the depth and make the drum thinner.This inevitably means that the drum must also be made thinner.

However, in conventional dryers of this type, the flow of heated air within the drum generally flows in the front-rear direction of the drum, that is, in the direction of the rotational axis. In this way, if the depth (length in the front-rear direction) of the drum is reduced to make it thinner, the diameter of the drum, that is, the length of the top and bottom, must be increased accordingly in order not to reduce the internal volume of the drum. However, the heated air is exhausted outside the drum before it is sufficiently filled from the top to the bottom of the drum, and the heat is not used effectively, resulting in poor drying efficiency. It has been considered that a number of holes are provided in the drum's peripheral wall to allow heated air to flow vertically inside the drum. This tends to block the heated air, making it impossible for the heated air to flow smoothly, resulting in longer drying times and poor drying efficiency.

The present invention has been made in view of the above points, and the positions of the intake hole that takes heated air into the drum and the exhaust hole that exhausts heated air from the drum are devised, and the intake hole is provided at the upper part of the opening in the end face of the drum. By providing the exhaust hole at a position 18o0 symmetrical with respect to the center of the drum of the intake hole and at a position shifted in the direction of rotation of the citrus, excellent drying efficiency can be obtained even when the drum is made thin. be.

The present invention will be explained below based on the drawings. Ill is a machine frame whose rear opening is covered with a back plate (2), and a horizontal drum (3) for storing clothes to be dried is rotatably provided inside the machine frame m. The drum (3) has a peripheral wall (4) and a rear wall (5) integrally molded from a synthetic resin such as polypropylene, and a front plate (6) is fixed to the front end of the peripheral wall (4). A plurality of baffles (7) are provided inwardly on the peripheral wall (4).
) are bulged out in one piece. The baffle (7) is a drum (
3) is sloped so that the height gradually increases from the front to the rear. The front plate (6) is fixed to the front end of the baffle (7) with screws (8).

The edge flange (11) of the front plate (6), which forms the front opening (9) of the drum (3), is connected to the outer peripheral 7 langes (1) and felt of the drum support plate 021 that partitions the inside and outside of the drum (3). 14). The drum support plate (1) has an annular shape with an opening in the center, and the center edge (151) is screwed to the peripheral edge of the clothes slot (17) provided on the front side of the machine frame (1). (101 is fixed with a stopper. The clothes input port 0η is covered with an elastic synthetic resin security cover (+81) and is opened and closed by the door (10).

The front surface of the door (19) is a transparent body ('aij). 1) has a protective cover θ~, a gasket to prevent air leakage between the door (1), a handle of the door (119),
(231 is the opening/closing shaft of the door.

A rotary shaft (26) is protruded from the center of the drum rear wall (5), and a cylinder (28) formed on the support plate (2'71)
This rotating shaft is inserted into the cylinder and is supported by two groups.

Before inserting the rotating shaft (2G) into the tube (28),
Several thrust washers (29) are inserted into the tube (6), and after inserting it into the cylinder (2), insert another thrust washer (24) and attach the washer (30) to the tip of the thrust washer (24).
Apply and tap the screw! 31) is screwed into the rotating shaft (26) and is prevented from coming out, and its movement in the thrust direction is restricted by the thrust washers (29) and (24). Both ends of the support plate (27) are fixed to the rear ends of both sides of the machine frame m. Note that the tapping screw (31) is threaded in the opposite direction to the rotational direction of the drum so that it does not loosen even when the drum (3) rotates. The drum (3) is connected to the rotating shaft (2) at the rear in this way.
6) is inserted into the barrel, and the opening edge (11) of the front plate (6) supports the drum support plate (11).
By fitting into the outer peripheral flange (13) of J, it is supported and rotatable.

The upper part of the drum support plate (12) has a large number of intake holes (32
1 is drilled, and a heater mounting plate (34) is attached to the position facing the drum support plate (national intake hole +321), and several honeycomb-shaped positive characteristic semiconductor heaters (a ) is attached.On the other hand, the drum support plate (1
2) A large number of exhaust holes (331) are bored at 180 degrees symmetrical to the intake hole +321 with respect to the center of the drum, that is, at positions 90 degrees apart from the bottom of the drum support plate in the direction of rotation of the drum. 4) In the figure, the rotation of the drum (3) is clockwise as shown by the arrow.A discharge port (■) is provided at a position facing the exhaust hole (33) on the front side of the machine frame (16), and the exhaust hole ( 33) is connected to this discharge port (36) by the exhaust duct (Ura).
). On the discharge port side, there is a filter (
38) is covered with a removable exhaust grill field.

There is an outside air intake (40
) is opened, and this outside air intake is connected to the rear filter +
It is closed by a removable intake grill (421) having a removable intake grill (41).A centrifugal fan (49) serving as a blower is disposed within the machine frame [11] facing the outside air intake port 140+.

This fan (4□□□ is a drive motor installed on the top of the machine frame (fixed to one end of the bamboo rotating shaft (45). On the back of the fan (43) is a cooling fan for the motor t44) + 4G) is formed. A small pulley (471) is fixed to the other end of the motor shaft (45).
A bell (481) is wound around the outer peripheral wall of the drum (3) and transmits the rotation of the motor (44) to the drum (3) via a small boob IJ- (4η) and a belt.

In such a configuration, when the motor (44) is driven, the drum (3) rotates and the centrifugal fan (43I) is driven.
The rotation of this fan (431) sucks outside air into the machine frame tll from the outside air intake port (40), making the pressure inside the machine frame a positive pressure higher than the outside pressure. The outside air is sent to the heater (to) as shown by the arrow in Figure (2),
There, it is heated and becomes hot air, which enters into the drum (3) through the intake hole (3), is exhausted to the outside of the drum through the exhaust hole (to), passes through the exhaust duct (ura), and exits the drum (30) through the discharge port (30). This excess culm removes moisture from the clothes and dries them.

By the way, the clothes (C)Vi in the drum (3) are swept up by the baffle (7) due to the rotation of the drum and fall. An air flow occurs in the rotational direction of the drum (3) (in the direction of arrow (A) in FIG. 8).

Therefore, the heated air that entered from the intake hole +32 is
8) As shown by the arrow in the figure, the air moves inside the drum along with the rotating air flow inside the drum. Here, in the drum, there are fewer clothes in the upper part than in the lower part, and since the drum support plate (the above-mentioned intake hole T32 at the top of I21) is provided in the upper part where there is less clothing, this intake hole (3 forces) If the air is blocked by the drum support plate (12J), a large amount of heated air will be drawn into the drum by the rotating air flow inside the drum and fan the clothes. 90 degrees in the rotational direction from the hole 1321 (1-80 symmetrical position with respect to the center of the drum)
Because they are located at different positions, the hot air entering the return hole (3) has a longer distance to exit from the exhaust hole. Therefore, the drying can be carried out more efficiently.In particular, as the drum becomes thinner, the outer contours of the inner parts of the drum are collectively shown.

In the above embodiment, an intake hole (32) and an exhaust hole (331) were provided on the drum support plate θ within the space between the front surfaces of the drum. An intake hole and an exhaust hole may be provided on the drum support plate in the rear opening, or an intake hole may be provided on the front (rear) drum support plate, and an exhaust hole may be provided on the rear (front) drum support plate. If the intake hole +321 and the exhaust hole (to) are provided on the front side of the drum as in the example, the outside air intake hole +40 provided on the machine frame
) and the outlet (to) are arranged on the front of the machine frame, which makes it easier to clean the intake grill (421 and exhaust grill Gg) provided at the outside air intake and the outlet.

In addition, in the case where a positive characteristic semiconductor heater (35) is used as a heater, the amount of heat generated increases as the amount of air passing through the heater increases. By taking in a large amount of heated air, the amount of air passing through the heater can be increased, and the heat generation array can be increased.

As described above, according to the present invention, the intake hole for introducing heated air into the drum is provided in the upper part of the end opening of the drum that is not easily blocked by clothing, and the intake hole is located 180 degrees from the center of the drum within the end opening of the drum. Since the exhaust hole is located at a position offset from the symmetrical position in the rotational direction of the drum, a large amount of heated air can be taken into the drum by utilizing the rotating air flow generated within the drum, and the distance from the exhaust hole to exit can be shortened. Make it longer,
During this time, the heated air that has entered the drum can sufficiently contribute to drying, and especially when the drum is made thinner by reducing its depth and increasing its diameter instead, the effect of the rotating air flow of the drum becomes remarkable, and even if the size is made thinner, sufficiently excellent drying efficiency can be obtained.

If, as in this example, outside air is sucked in through the outside air intake to increase the pressure inside the machine frame and supply heated air to the drum, an air intake duct is required from the outside air intake to the intake hole of the drum. This makes it possible to promote the thinning of the stop frame without having to do so.
