Abstract

PURPOSE:To evenly raise the temperature of a bedquilt by providing a cord-like heater around the entire circumference of the outer circumferential part of a drying bag so as to quickly raise the temperature to such a degree that ticks can be extirpated, so that ticks on the entire surface of the bedquilt surface cloth being in contact with the drying bag can be securely extirpated, and also the shape of the outer circumferential part can be maintained in such a condition that the bedquilt surface cloth is brought into contact with the drying bag. CONSTITUTION:First, a drying bag 7 is inserted between a coverlet 11 and a mattress 12, and the connecting part is connected to the warm-air blowing part 6 of a body 1, then the body 1 is electrically connected with a cord-like heater 9. Next, the body 1 is operated to supply warm air into the drying bag 7 through a warm-air producing device 5 so as to swell out the drying bag, so that warm air comes out from the entire surface thereof to gradually increase the temperature of the bedquilt, thus moisture can be removed to complete drying. In this case, the cord-like heater 9 is simultaneously electrified so as to be heated, and the bedquilt surface cloth being in contact with the circumferential part of the drying bag 7 is heated to a temperature higher than 50 deg.C in a short time, so that ticks cannot get away to a lower temperature place and are extirpated. Further, even if the drying bag 7 is swelled, the outer circumferential shape thereof is not changed, and the temperature of the bedquilt surface cloth can be almost evenly raised.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a futon dryer for drying futons using warm air.

Conventional Technology In recent years, futon dryers have been used to easily dry futons indoors due to inclement weather or when there is no place or time to dry the futons. Friend, as housing structures have become more airtight in recent years, there has been an increase in mold growth and the breeding of dust mites, and the breeding rate of dust mites on futons has also been on the rise. At the same time, it is expected that mites can be killed at high temperatures.

Conventionally, this type of futon dryer has had a configuration as shown in FIG. That is, a dry tR103 made of nylon fiber etc. is placed between the comforter 101 and the mattress 1o2.
is inserted. The dryer main body 104 has a hot air generating device including a fan motor, a heater, etc. inside the dryer main body 104, and this hot air generating device communicates with a hot air outlet 105 provided outside the dryer main body 104. A cylindrical bellows-type connection hose 106 is connected to the hot air outlet 105, and one end of the connection hose 106 is connected to the drying bag 1o3, so that the drying bag 103 is swollen by the hot air supply, thereby improving breathability. Warm air is blown out from the entire surface of the drying bag 103. This was intended to pass through the inside of the comforter 101 and mattress 102 and heat and dry them, as well as to kill the mites living on the comforter.

Problems to be Solved by the Invention In such a conventional configuration, warm air blown from the drying bag 103 gradually increases the temperature of the comforter 101 and the mattress 102 to dry the comforter. The mites living on the futon on the side that is in contact with the bag 103 will be deprived of the moisture in its body and die if the temperature rises rapidly.
When the temperature rises gradually, the mites become more active and wander around the surface of the futon in an attempt to escape to a place with a lower temperature. At this time, the outer fabric 1 adjacent to the center of the drying bag 103
The mites on o1& will die without being able to escape, but the drying bag 10
Dust mites on the outer fabric 101a located toward the edge of the dryer bag 1
I moved to a lower temperature area away from 03,
This method had the problem of not being able to completely exterminate mites.

Further, when the drying bag 103 expands, the shape of the outer peripheral part 103a of the drying bag 103 changes, causing unevenness and causing the futon 102
Since the futon 102 does not come into close contact with the outer fabric 101a of the futon 102, the temperature of the futon 102 does not rise sufficiently.

The present invention solves these problems, and at the same time as the futon drying, it reliably kills the mites that are parasitic on the outer fabric of the futon on the side that contacts the drying bag, and also allows the futon drying without deforming the outer periphery of the drying bag. The purpose is to provide a machine.

Means for Solving the Problems In order to solve this problem, the present invention provides a hot air outlet that communicates with a hot air generator built into the main body, and connects a drying bag that can fully ventilate to this hot air outlet. , the drying bag has a cord-shaped heater disposed on its outer periphery, and the cord-shaped heater can generate heat simultaneously with the operation of the hot air generator, and has the following configuration.

Function: With this configuration, hot air is evenly supplied from the hot air generator to the futon through the drying bag, and at the same time, the cord-shaped heater installed on the outer periphery of the drying bag generates heat to reach the temperature that kills mites. When the temperature is rapidly raised to over °C, the cord-shaped heater reinforces the outer periphery of the drying bag.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. As shown in the figure, the main body 1 includes a fan motor 2 for blowing air.
The hot air generating device 6 includes a heater 3, a casing 4, and the like, and is provided outside the main body 1 and communicates with an air outlet 6. A drying bag 7 made of nylon fiber or the like that can provide a predetermined amount of ventilation has a cord-shaped heater 9 sewn into the entire outer circumference 8, and a connection port 1 provided at the end of the drying bag 7.
When the cord heater 9 is connected to the hot air outlet 6 in communication with the warm air outlet 6, the cord heater 9 is also electrically connected to the hot air generator 5 of the main body 1, and is energized and generates heat at the same time as the main body 1 is operated.

In the above configuration, the following 1. To explain the operation, first,
Insert the drying bag 7 between the comforter 11 and the mattress 12, and connect the connection port 10 of the drying bag 7 to the hot air outlet 6 of the main body 1.
When the cord-shaped heater 9 and the main body 1 are connected to each other, the cord-shaped heater 9 and the main body 1 are electrically connected. Next, when the main body 1 is operated to supply warm air to the drying bag 7 from the hot air generator 5, the drying bag 7 expands due to the pressure of the hot air, and hot air comes out from its entire surface. , the inside of the futon is ventilated to gradually raise the warm air inside the futon, removing moisture and drying the futon. At this time, the cord-shaped heater 9
is simultaneously energized and generates heat, raising the temperature of the futon outer cloth in contact with the periphery of the drying bag 7 to over so'c in a short time. According to the actual measurement example shown in Fig. 4, at a room temperature of 20''C, it takes about 16 minutes from the start of operation for the surface temperature of point A of the futon outer fabric in contact with the center of the drying bag 7 to reach 60°C or higher. Compared to this, the surface temperature of the futon outer fabric at point B, which is in contact with the cord-shaped heater 9 of the drying bag 7, reaches 50°C or more within 6 minutes from the start of operation. Dust mites on the cloth are blocked by the heat of the cord-shaped heater 9 and cannot escape to a lower temperature area, so that they can be killed.

Furthermore, since the cord heater 9 surrounds the outer periphery of the drying bag 7, even if hot air is supplied to the drying bag 7 and it expands, the outer periphery shape of the drying bag 7 does not change, and the futon outer fabric is almost uniformly distributed. The temperature can be raised to .

Effects of the Invention As described above, according to the present invention, a cord-shaped heater is provided all around the outer periphery of the drying bag to quickly raise the temperature at which the outer periphery of the drying bag can kill mites. It is possible to reliably kill dust mites living on the entire surface of the futon fabric that comes in contact with them without letting them escape, and by installing a cord-shaped heater on the outer periphery, drying is possible without changing the shape of the outer periphery of the drying bag into an uneven shape. To realize an excellent futon dryer that can inflate a bag, maintain a state of contact with the futon outer fabric, and uniformly raise the temperature of the futon outer fabric.
