[0002]

2. Description of the Related Art In recent years, an increasing number of households use clothes dryers to dry clothes, but when hot air is applied to clothes in the clothes dryer, ingredients such as chemicals are mistakenly added to clothes. If there is adherence, it may cause ignition and burn clothes dryer. Therefore, it is common to cover the drying chamber with an iron plate as much as possible and to avoid putting chemicals and other substances attached to the product instruction manual.

[0003]

In such a conventional clothes dryer, the confirmation of combustion is delayed, and the weight is large because it is covered with an iron plate, which makes it inconvenient to carry at home and unsuitable for practical use. However, there are problems that sufficient fire prevention measures have not been taken, such as it is often difficult for people who use clothes dryers to determine whether chemicals that are easily ignited are attached.

The present invention solves the above-mentioned problems, and by stopping the power supply to the equipment in accordance with the temperature condition in the drying chamber, even if a combustion condition should occur, it is possible to minimize the spread of burning to the room. The first purpose is to stop.

A second object is to enable a user to detect the combustion early even if it should burn.

In order to achieve the first object of the present invention, a hot air driving means for applying hot air to clothes to be dried in a drying chamber and a temperature detection for detecting the temperature in the drying chamber. Means, control means for controlling the operation of the hot air drive means by the output of the temperature detection means, abnormality detection means for outputting an output when the temperature detected by the temperature detection means exceeds a predetermined temperature, and the dryer main body Power supply control means for stopping the power supply of, and a remote fire extinguishing means for remotely controlling the automatic fire extinguisher provided in the room where the dryer main body is installed, the control means, the output by the abnormality detection means The first problem solving means is to operate the power supply control means to stop the power supply to the dryer main body and automatically operate the remote fire extinguishing means.

In order to achieve the second object, in addition to the first problem solving means, an abnormal state informing means for informing that an abnormal state is present is provided, and the control means outputs the output of the abnormality detecting means. The second problem solving means is that the abnormal state informing means is operated according to the above.

[0008]

According to the first means for solving the above problems, the present invention provides:
When the clothes to be dried are burned, the power supply to the clothes dryer is stopped, the fire can be extinguished early, and the burning of the clothes can be stopped to a minimum.

Further, by the second means for solving the problem, even if a combustion state should occur, the user can detect that fact at an early stage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

As shown in the figure, a rotary drum (dryer) 1
Is a rotatably arranged inside a housing (not shown), and clothes to be dried (not shown) are provided inside the rotating drum 1.
Is supplied, is rotationally driven by the motor 3 driven by the motor drive means 2, and hot air is sent by the hot air drive means 4. A plurality of convex baffles (not shown) are arranged inside the rotating drum 1. When the rotating drum 1 rotates, the clothes to be dried are caught by the baffle and lifted to the upper part, and after reaching almost the apex, By dropping to the bottom, hot air is evenly applied to the clothes to be dried. The temperature sensor (temperature detecting means) 5 is arranged near the hot air outlet of the rotary drum 1 so that the temperature of the moist hot air after the hot air has passed through the clothes to be dried can be detected. The output of the temperature sensor 5 is input to the control means 6 to control the operations of the motor 3 and the hot air drive means 4 to perform predetermined drying control. The abnormality detecting means 7 outputs an output to the control means 6 when the temperature detected by the temperature sensor 5 exceeds a predetermined temperature. The power supply control means 8 operates by the output of the control means 6, and the motor 3
The power supply to the hot air drive means 4 is stopped. The remote fire extinguishing means 9 remotely controls the automatic fire extinguisher 10 installed in the room where the dryer main body is installed. The abnormal condition notification means 11 is for notifying that the abnormal condition is present. The control means 6 operates the power supply control means 8 by the output of the abnormality detection means 7, stops the power supply of the motor 3 and the hot air drive means 4, automatically operates the remote fire extinguishing means 9, and operates the automatic fire extinguishing apparatus 10. At the same time, the abnormal state notification means 11 is operated.

To explain the operation of the above structure, first, the clothes to be dried containing water are stirred and heated in the rotating drum 1, so that the water contained in the clothes to be dried is vaporized and removed from the rotating drum 1. Is discharged. As for the surface temperature of the clothes to be dried, as shown in Fig. 2 (a), there are many low temperature parts. During drying, most of the hot air energy is lost to the evaporation of water from the clothes to be dried, so that the surface temperature of the clothes to be dried cannot rise rapidly and the steady state continues for a while. When the drying progresses and the steady state ends, the proportion occupied by the high temperature part gradually increases, but from this point the surface temperature of the clothes to be dried tends to rise rapidly, and it is easy to cause ignition of chemicals attached to the clothes. Become. FIG. 3 shows the temperature characteristics inside the rotary drum 1 by the temperature sensor 5 when normal clothes are dried with the rated capacity of the dryer. As the drying of the clothes to be dried progresses, the temperature inside the rotary drum 1 increases. You can see that it rises in stages. Further, when the amount of clothes to be dried is small or the clothes have been dried to some extent from the beginning, the temperature easily rises rapidly as shown by the characteristic a in FIG. 4, so that the clothes are less likely to be damaged by heat. As described above, when the temperature exceeds the predetermined temperature B, the supply of hot air is weakened for a predetermined time or changed to cold air so that the temperature in the rotary drum 1 is controlled not to rise more than necessary, and during that period, the material to be dried is dried. Although the clothes are dried, when the chemicals or the like attached to the clothes to be dried ignite, as shown in the characteristic b of FIG. 4, even after the hot air is stopped when the temperature exceeds the predetermined temperature B, The temperature does not drop and continues to rise. Therefore, when the predetermined temperature C is reached, the abnormality detection means 7 outputs an output, the control means 6 simultaneously stops the stirring operation of the rotary drum 1 by the hot air drive means 4 and the motor 3, and the progress of the burning of the ignited clothes. Prevent rapid progress. At this time, the control means 6 can automatically operate the remote fire extinguishing means 9 and operate the automatic fire extinguishing apparatus 10 to carry out the fire extinguishing activity earlier. Further, by operating the abnormal condition notification means 11 to perform the abnormal notification, it is possible to notify the occurrence of a fire at an early stage.
