The present invention relates to a dryer such as a garment for drying a dry item by accommodating the dry matter in a rotating drum, and supplying and exhausting heated air into the rotating drum.

Some dryers, such as clothes, are used to blow hot air into a rotating drum and dry the dried object by the hot air. This type of rotating drum has a rotating drum (shown in FIGS. 1 and 2). 10) is disposed so as to rotate freely, and the rotating drum 10 is supported by a rear wall of the casing 1 or an attachment plate formed on the casing 1 so as to be freely rotated and at the same time the front of the rotating drum 10. The periphery of the opening is supported by a support ring (3) fitted here to support both front and rear ends of the rotating drum (10) freely for rotation. In addition, an intake fan F is provided at the center of rotation of the rear wall, and a hot air supply port 30 is formed in the support ring 3 to exhaust the exhaust gas from the intake fan F. And the center opening part of the said support ring 3 is closed by the opening-closing cover 13 supported by the casing 1. In the dryer of this type, the rotary drum 10 is driven by the motor 15 and the heated air from the heating device 31 provided upstream of the hot air supply port 30 is rotated. It is configured to be supplied to the inside, the opening and closing the cover 13, the object to be dried (M) such as clothing, and the heating device (31) and the motor (15) in the state of closing the opening and closing cover (13) When the driving state is set, the dry object M in the rotating drum 10 is rotated and dried by the heating air.

Moreover, this conventional thing is provided with the electrode sensor S2, and this electrode sensor S2 is made to detect the drying degree of clothing. In such a conventional dryer, since the detection accuracy of the drying degree is insufficient, it is conceivable to install the clothes temperature sensor S1 separately to increase the detection accuracy of the drying degree and to plan the improvement of safety.

As described above, as shown in FIG. 2, the clothing temperature sensor S1 and the electrode sensor S2 are exposed to the inner surface of the support ring 3 as the rotating drum 10 as shown in FIG. In addition to being attached to the portion, in the rotational direction of the rotating drum 10, the hot air supply port 30 is formed in parallel, so that the object to be dried M is provided with the hot air supply port 30. Immediately after passing, the detection accuracy can be increased, and the drying operation can be accurately executed because the drying operation is controlled by the detection outputs of the clothes temperature sensor S1 and the electrode sensor S2.

However, even in such an improved dryer, the detection accuracy of the clothing temperature sensor S1 and the electrode sensor S2 is insufficient. This is because the detection accuracy of the clothing temperature sensor S1 and the electrode sensor S2 is affected by the contact area between the detection unit of the sensor and the moving object M. In other words, the larger the contact area, the higher the detection accuracy, and the smaller the contact area, the lower the detection accuracy. By the way, in the above-mentioned dryer, since the detection part protrudes from the attachment surface, and the clothing temperature sensor S1 and the electrode sensor S2 are formed in parallel, the contact with the to-be-dried object M to which these sensors move is mutually. Will interfere. Therefore, since the sensing object of each sensor and the to-be-moved object M which move are not reliably contacted in all the area | regions, the contact area with the to-be-damaged object M of the sensor part of a sensor becomes inadequate, the detection precision falls, and it malfunctions. As a result, heating may be insufficient or overheating.

The present invention has been made in view of the above-mentioned, "The heated air is supplied into the rotating drum 10 to heat and dry the dry matter (M) accommodated therein, and to discharge the wet air in the rotating drum 10 to the outside A dryer of the type, comprising: a clothes dryer (S1) and an electrode sensor (S2) for drying control attached to the fixed wall facing the inside of the rotating drum (10) in a protruding state. And the detection accuracy of electrode sensor S2 are made into the subject.

[Invention of claim 1]

The technical means of the present invention for solving the above problems is "arrangement of the clothing temperature sensor S1 and the electrode sensor S2 deviating from each other in the radial direction of the rotating drum 10". The technical means of the present invention act as follows.

When the dry object M is accommodated in the rotating drum 10 and put into an operating state, heated air is supplied, and the dry air M is heated and dried by the heating air, and the wet air in the rotating drum 10. Is discharged to the outside.

At this time, the clothing temperature sensor (S1) and the electrode sensor (S2) for the drying control in the rotating drum 10 is installed in the radial direction of the rotating drum 10, so that the sensor to move the building It does not disturb contact with (M). Therefore, since each said sensor and the to-be-dried object M which move are reliably and in substantially the whole area | region, it is possible to ensure sufficient contact surface WJR between these sensors and the to-be-made object M. FIG.

According to the above configuration of the present invention has the following unique effects.

Since the to-be-dried object M which moves with respect to each of the clothing temperature sensor S1 and the electrode sensor S2 is separately and reliably contacted with each other, the contact area between these sensors and the to-be-made object M can be sufficiently secured. As a result, detection accuracy can be improved to prevent heating shortage or overheating.

[Invention of Claims 2 and 3]

These inventions are limited to the arrangement of the clothing temperature sensor S1 and the electrode sensor S2 and the configuration of the detection unit according to claim 1 of the claims, and the "clothing temperature sensor S1 and the electrode sensor S2. In the invention in which each of the sensors is separated from each other in the radial direction and the rotational direction of the rotary drum 10, the detection accuracy of these sensors is prevented because the sensors do not further interfere with the moving object M. In the invention, the detection unit of each sensor is inclined such that the detection unit of the clothing temperature sensor S1 and the electrode sensor S2 is inclined so that the protrusion height becomes high along the moving direction of the object M.
