Description

Description: TECHNICAL FIELD The present invention relates to a clothes dryer for drying clothes and the like.

2. Description of the Related Art As shown in FIGS. 4 and 3, a conventional clothes dryer for inserting and removing clothes from an upper surface portion includes an upper frame 42 above an outer frame 41. As shown in FIG.
When the lid 43 that covers the clothes insertion / removal opening provided in the upper frame 42 is opened, the opening provided in the cylindrical body of the rotating drum 44 is covered, and the opening / closing can be freely opened and closed along the cylindrical body. The drum cover 45 which can be moved is located, and a drum cover position detecting device is provided so that the operation does not proceed unless the drum cover 45 is completely closed. This drum lid position detecting device includes a magnet 46 fixed to the drum lid 45 and a proximity switch 47 provided at a non-rotating portion position close to the rotation locus of the magnet 46. When the drum lid 45 is closed, the drum lid 45 is closed. The cover plate 48 that compresses the lid spring 48 that urges the magnet in the opening direction and shields the magnetic force covers the magnet 46 of the drum cover 45.

Then, the drum cover 45 is attached with a stopper (for example, 3 in FIG.
When it is not closed by 0), the drum lid 45 is slightly pushed open by the lid spring 48, the magnet 46 is exposed from the shielding plate 49, and the proximity switch 47 is operated. It is configured to recognize that there is a fault, stop the operation, and report an abnormality. Therefore, without the lid spring 48, it was not possible to detect that the user had forgotten to put the stopper, and there was a risk that the cover would be rotated as it was.

Problem to be Solved by the Invention The present invention solves the above-mentioned problems, and in a clothes dryer of a type in which clothes are inserted and removed from an upper surface portion, a drum cover that covers an input port of a rotating drum is securely fixed by a stopper. It is an object of the present invention to provide a clothes dryer capable of detecting that it is locked with a simple configuration.

Means for Solving the Problems In order to solve the above problems, the clothes dryer of the present invention comprises:
The drum lid is disposed on the outer frame front side from the vertical direction where the center of gravity of the drum lid passes through the center of the rotating drum, and when the stopper is opened, the drum lid moves in the direction in which the charging port is opened by the weight of the drum lid. The position of the drum lid is configured to move, the magnet is provided on the drum lid, and the proximity switch is provided at the non-rotating portion closest to the magnet of the drum lid when the drum lid is closed, and the proximity switch does not operate Sometimes
The operation is stopped and an abnormality is notified.

Operation With this configuration, when the drum cover is closed, the weight of the drum cover applies a force to the drum cover movable along the cylindrical body of the rotary drum to rotate the drum cover with respect to the rotation center of the drum. If the user forgets to use the stopper, the drum lid naturally moves in the direction that opens the drum slot, so the magnet provided on the drum lid moves away from the proximity switch provided at the non-rotating part position, making it easy to use the magnet. , And the fact that the drum lid is open can be detected.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional front view of a clothes dryer according to an embodiment of the present invention, and FIG. 2 is a partial sectional side view of the clothes dryer. 1 and 2, reference numeral 1 denotes an outer frame, 2 denotes an upper frame attached to the outer frame 1, 3 denotes an openable / closable lid provided on the upper surface of the upper frame 2, and 4 denotes a rotation inside the outer frame 1. It is a cylindrical rotating drum that is freely supported. The rotary drum 4 has a charging port for inserting and removing clothes in its cylindrical body, a drum cover 5 that can be opened and closed at the charging port, and a cylindrical support cylinder 6 on one end surface side of the rotary drum 4. Is rotatably supported by a front support plate 7 fixed to the outer frame 1 via a bearing member 8, and is fixed to a casing 10 via a bearing 9 fixed to the center of the other end surface of the rotary drum 4. The shaft 11 is rotatably supported. Numeral 12 denotes a heat exchange type blower arranged in the casing 10, which blows each of the drying air a and the cooling air b by the partitioning portion 13 of the casing 10, and exchanges heat between the two airs. An intake port 14 is provided in a casing 10 around the shaft 11 facing the rotating drum 4. On the other hand, a heater cover 16 in which a heater 15 is provided is fixed to the front support plate 7, and an inflow port 17 is provided at a position of the front support plate 7 facing the heater 15. An outlet 18 for drying air a is provided on the end surface of the rotating drum 4 to which the bearing 9 is fixed,
A filter cover 20 that covers the outlet 18 and holds a filter 19 having a mesh part for collecting lint is detachably provided. The casing 10 is fixed to a casing support plate 21 fixed to the outer frame 1. A motor 23 is fixed to a connecting plate 22 fixed to the front support plate 7 and the casing support plate 21, and a pulley 24 for driving a drum and a pulley 25 for driving a fan are provided on the motor 23. 4 and pulley of heat exchange type blower 12
A drum belt 27 and a fan belt 28 are stretched between the rotating drum 4 and the heat exchange type blower 12. The drum cover 5 is fitted and supported in guide grooves 29a and 29b provided along the cylindrical body at the input port of the rotary drum 4, and moves freely along the cylindrical body. As shown in FIG. 3, the drum lid 5 is locked by a stopper 30 so as to close the insertion port 31. Therefore, when the drum cover 5 is opened, the stopper 30 is opened and the guide grooves 29a, 29b are opened.
When the drum cover 5 is moved along, the charging port 31 is opened.

The drum cover 5 is arranged such that the center of gravity of the drum cover 5 is located on the front side of the outer frame 1 from the vertical direction passing through the center of the rotating drum 4. Works downward due to its own weight,
The drum opening 31 is automatically opened by the weight of the drum cover 5 due to its movement along the cylindrical body, being restricted by the guide grooves 29a and 29b. On the other hand, a magnet 32 is fixed to the drum lid 5, and a proximity switch 33 is provided at the position of the non-rotating portion closest to the drum lid 5 when the drum lid 5 is closed by the stopper 30. Therefore, when the drum cover 5 is closed, the proximity switch 33 is in the operating state. Conversely, when the stopper 30 is removed and the drum cover 5 is opened, the drum cover 5 is completely opened. Therefore, the range of the magnetic force of the magnet 32 provided on the drum cover 5 causes the proximity switch 33 to operate. You will immediately move out of range. When the non-operation of the proximity switch 33 is determined by the drum lid position detecting device, the operation is stopped and the abnormality is notified.

Effect of the Invention As described above, according to the present invention, the drum lid is automatically moved by simply removing the stopper, and the input port of the rotating drum is opened, so that the opening and closing of the lid during the work of inserting and removing clothes is performed. The operation becomes simple, and the usability can be greatly improved even in a conventional clothes dryer in which clothes are inserted and removed from the upper surface. Also, when not locked by the stopper,
The drum lid is completely opened by its own weight, and there is no slight difference in position between whether the drum lid is closed or open as in the conventional case, so a simple lid that does not require a conventional lid spring With this configuration, it is possible to prevent forgetting to close the drum lid, and the effect is great.
