Abstract

(57) [Abstract] [Purpose] It is an object of the present invention to provide a futon dryer that safely controls the temperature of hot air blown out. [Constitution] P facing the blower outlet of the futon dryer
A TC heater is provided, and a damper for adjusting the ventilation surface is provided on the front surface of the PTC heater. During normal futon drying, the damper is lowered to narrow the ventilation surface to reduce the power consumption of the PTC heater, thereby keeping the warm air temperature constant. It is characterized in that the temperature is kept low, the damper is raised in the case of elimination of ticks, the ventilation surface of the PTC heater is expanded, the power consumption is increased by increasing the ventilation surface, and the warm air temperature is raised.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a futon dryer, and more particularly to a futon dryer having a function of blowing warm air for combating mites.

[0002]

[Prior Art]

 In conventional futon dryers, the temperature of the warm air warmed by the heater is made almost constant, and the time to blow air is set by a timer depending on the size of the futon to be dried. In the case of extermination, a method of increasing the temperature of hot air to be blown out by increasing the number of heaters for energizing a plurality of heaters provided at the blower outlet with a changeover switch or the like is adopted. In this case, if there is an obstacle on the connection hose side or the suction side of the blower, the air volume of the blower will decrease, the heater will overheat and the surrounding temperature will rise, causing damage to the equipment or melting of the built-in temperature fuse. Is occurring.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned conventional problems, and it is possible to send hot hot air for combating mites, and obstacles are placed on the blowing side or the suction side to block ventilation. In this case, it is an object of the present invention to provide a futon dryer that prevents accidents such as damage to the equipment due to overheating of the heater and melting of the built-in temperature fuse.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the temperature of the hot air is changed by adjusting the ventilation surface of the PTC heater with a damper.

[0005]

[Action]

 According to the above configuration, the ventilation surface of the PTC heater is changed by the damper provided on the front surface of the PTC heater, and the warm air temperature is adjusted from the power consumption of the PTC heater according to the ventilation surface. In addition, when an obstacle is placed on the blower side or suction side of the blower and ventilation is obstructed, the PTC heater reduces overflow by reducing the amount of ventilation, thus preventing overheating, damage to the equipment, and built-in equipment. It is designed to prevent accidents such as melting of the thermal fuse.

【Example】

 Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a plan view showing the details of the present invention, and FIG. 2 is a side sectional view of the same part seen from the side of the blower 1. At the blower outlet of the blower 1, there are a plurality of stacks facing the blower outlet. The PTC heater 2 is provided, and hot air is blown out between the PTC heaters 2. A damper 3 is provided on the front surface of the PTC heater 2. By operating a spring 4 provided on the damper 3 and a slide mechanism 5 provided on the upper surface of the device, the damper 3 slides on the inclined surface at the upper end of the damper to move the damper 3 in the vertical direction. The temperature of the PTC heater 2 is adjusted by covering the front surface of the PTC heater 2 and changing the ventilation surface.

When performing normal futon drying, as shown in FIG. 3, the damper 3 is lowered to cover about 1/4 of the upper portion of the PTC heater 2 to reduce the heat generation amount and keep the warm air temperature at a constant low level. I have to. In this state, if an obstacle is placed on the suction side or blowout side of the blower 1, the ventilation amount of the blower 1 will decrease, and the heat generation amount of the PTC heater 2 will decrease due to the reduction of the ventilation amount, and the temperature inside the equipment will overheat. It is possible to prevent damage to the equipment and blowout of the thermal fuse. When mites are eliminated, the damper 3 is raised and air is blown from the blower 1 over the entire surface of the PTC heater 2 to increase power consumption and heat generation, thereby increasing the warm air temperature and shortening mites elimination. Can be done in time.

[0008]

[Effect of the device]

 As described above, in the present invention, the damper is provided in front of the PTC heater provided at the blower outlet of the blower, the ventilation surface of the PTC heater is adjusted by the damper, and the hot air temperature of the futon dryer is controlled. It is possible to eliminate mites safely and in a short time without causing accidents such as damage to the fuse and melting of the thermal fuse.
