Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bedding dryer capable of drying bedding such as comforters.

[0002]

2. Description of the Related Art Conventionally, as a drying device of this type, FIG.
And had a structure as shown in FIG.

That is, the user himself sandwiches the cloth-made air-blowing mat 3 between the box sheets 1 and the comforter 2 covered by the bed mattress, and the air-blowing holes 4 and the ventilation paths 5 provided at the end of the air-blowing mat 3 are provided. And the hot air generator 6 having an electric heater are communicated with each other through the air passage 5, so that the hot air is sent to the blower mat 3 and the hot air is blown through the cloth into the bed sheets. 1 and the bed pad or bed mattress thereunder, or the comforter 2 is dried.

[0004]

However, in the conventional structure as described above, the blower mat 3 is inserted into the center of the bedding by a person and the wrinkles are extended for each use, and the ventilation passage 5 and the warm air generator 6 are set. It was troublesome to do and was inconvenient to use.

In addition, if a sleeping person keeps sleeping with this dryer set and hot air is generated, the blowing mat 3 forming a bag-shaped container has a wide warm air passage, and the warm air is blown from the whole cloth. Since it blows out, warm air hits the human body, and there is a risk of dehydration, low-temperature burns, etc. Even if a means for detecting an abnormal temperature rise is provided, the warm air will circulate through the wide hot air passage, resulting in responsiveness. There was a problem that it could not be said to be a good detection means.

In order to solve the above-mentioned problems, an air passage that is closed by a human body load is provided inside the air blowing mat to prevent the diffusion of warm air when the human body sleeps and improve the safety. As a result, the air passage is closed and a very high internal pressure is applied. This and the flexure of the mattress due to the load on the human body act in the same way, and the ventilation passage is easily disengaged from the ventilation hole of the ventilation mat, which causes a problem that a rework is required every time the vehicle is operated.

Further, since the air passage is provided inside the air blowing mat and the air blowing mat is permanently installed, the air blowing mat and the air passage are rubbed against each other due to the load when the human body is sleeping, and especially the sewn portion and the attachment sewing portion of the air passage are worn. There was also a problem that hot air leaked due to high internal pressure when the air passage was blocked.

Therefore, the present invention saves the trouble of attaching and detaching each time of use, and there is no fear of dehydration or low temperature burn even if a dry operation is performed while one person is sleeping. It is an object of the present invention to provide a high-quality futon dryer and a highly reliable fixed-type futon dryer capable of performing stable blast drying with good durability.

[0009]

In order to achieve the above object, a futon dryer of the present invention detects a blower bag, an attachment means for attaching the blower bag to bedding, a blower, a heater, and a warm air temperature. A warm air unit having a built-in temperature detecting means, a blower opening provided on the outer peripheral portion of the blower bag so as to communicate with the blowout opening of the warm air unit, and the blower opening across the longitudinal direction of the blower bag. An air passage provided inside the blower bag, the blower opening and the air passageway are sewn into a tubular shape, and then the upper material of the blower bag in a state in which the blower opening is folded toward the wind passage side. Sew all around the folded part together with the peripheral part of the lower fabric,
Then, pull out the blow-out port to the outside to
It is configured to be formed of a tubular fabric of a book.

[0010]

According to the present invention, with the above structure, the warm air flows into the blower bag attached to the bedding through the air passage, the hot air diffuses through the cloth, and the entire bedding is uniformly dried in the used state. In addition, the air passage is blocked by the load of the human body during sleep, and the human body is not adversely affected by the warm air. Further, the safety mechanism has good durability and stable blast drying.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a futon dryer of the present invention will be described below with reference to the drawings. In FIG. 2, reference numeral 7 denotes a thin warm air unit having a blower, a heater, and a detection means for detecting an abnormal temperature rise, which is attached to the bed 8 substantially at the center of the side and sewn in a box shape so as to wrap the mattress 10. The warm air is communicated with the blower sheets 11 and the duct 9.

At the center of the long side of the upper surface of the blower sheet 11, there is a blowing port 12 protruding from the sheet, and the tip of the L-shaped duct 9 is inserted into the blowing port 12.
It is designed to be fastened with a velcro tape 13 at the end. In addition, a blower bag 14 is provided on the bed surface of the blower sheet 11.
A tubular air passage 15 is provided in the interior thereof so as to communicate with the blow-in port 12 and cross the bed surface.

FIG. 1 and FIG. 3 are a partially cutaway sectional view from the foot, a partially sectional perspective view of a suction port and a partially cutaway side sectional view in the same embodiment. Blower sheets 11
Is the bottom cloth 1 from the back to the bed surface of the upper cloth 17 sewn in a box shape so as to wrap around the mattress 10 and the bed pad 16.
The blower bag 14 is configured by sewing 8 around the outer periphery, and the blower bag 14 has a cylindrical shape that penetrates the cutout portion at the center of the long side of the blower bag 14 and crosses the bed surface inside the blower bag 14. An air passage 15 is provided. The air passage 15 is 30 all around
It has a tubular shape of cm and a length of about 85 cm with respect to a bed width of 1 m, and only its tip is sewn to the lower fabric 18 so as to have a sufficient expansion margin.

The warm air unit 7 is attached to the bedside by the load of the mattress or the like by inserting the flat plate portion of the L-shaped metal fitting 19 fixed to the back surface between the mattress 10 and the bed floor plate 20. Has been. In addition, the arrow in FIG. 2 is an inflow line of warm air.

FIG. 4 is a partial cross-sectional perspective view of the blowing port 12. The blow-out port 12 and the air passage 15 are first sewn into a tubular shape, and then the cut-out portion of the upper cloth 17 and the lower cloth 18 are folded in the air passage 15 side.
At the same time, the folded-back portion is sewn all around, and is then drawn out to the outside. As a result, the blow-in port 12 and the air passage 15 are made of one tubular material.

The upper cloth 17 and the lower cloth 18 are high-density plain weaves made of 100% cotton for both the warp and weft, and both warp and weft are made of cotton count # 40 and have a warp density of 125 / inch and a weft density of 11
It is finished with 5 pieces / inch. In addition, in order to control the air permeability of the fabric in the finishing process, resin processing and crushing with a high-pressure calender are performed, and the air permeability of the fabric is set to 2.0 cc / cm ² · sec (measured by JIS L 1096 flange type method) or less. is doing. This fabric air permeability does not change much in general household washing due to resin processing and shrinkage of cotton fibers.

Further, the cloth forming the air passage 15 and the blowing port 12 is made of 100% nylon 7
It is a high-density plain woven fabric using 0 denier filament yarn, and is nylon taffeta whose air permeability is set to 0.3 cc / cm ² · sec or less by resin processing and heat setting with a calendar. This also has little change in air permeability in general home laundry,
Excellent in tensile strength, tear strength and wear strength.

Next, the operation of the structure of this embodiment will be described. First, the user operates the switch of the hot air unit 7 to start the energization of the fan and the heater therein, and the hot air is sent to the duct 9. When the operation is performed normally, warm air is sent into the air passage 15, the air passage 15 expands as the pressure increases, and the warm air reaches the inside of the blower bag 14 and eventually the dough increases as the internal pressure increases. Warm air diffuses into the bed through the eyes. Accordingly, not only the bed pad 16 and the mattress 10 but also the comforter on the blower sheet 11 can be uniformly dried.

In this operating state, the shape of the air passage 15 is cylindrical, and the cross-sectional area of the open end of the air passage is the blowing port 12
The blower bag 1 having the same size as the
The air blowing load on No. 4 does not increase much compared to when there is no air passage, and smooth air blowing can be performed as before. Further, in the conventional configuration including only the air blower bag, when the heavy comforter is placed, the futon does not rise at the blow-in port and hot air may not flow into the air blower bag. However, the air passage 15 of the present invention is provided. Due to the high internal pressure in the air passage, it is easy to obtain an air passage for pushing up the futon, and it is easy to obtain a trigger for warm air inflow. This is more effective as the air permeability of the fabric forming the air passage 15 is smaller.

When the futon drying performance was examined, when a warm air of about 60 ° C. was blown at an internal pressure of 10 mmAq and an air volume of 0.5 m ³ / min, a standard damp futon (100% cotton, 5 kg, 300 g) was softened in about 2 hours. I knew I could do it.

Next, the operation at the time of abnormal operation when a person is sleeping in the bed will be described. As in normal operation, warm air is blown into the air passage 15, but since the air passage 15 crosses the center of the bed surface, it is almost 100 for an adult.
% A human body load is applied on the air passage, and the air passage 15 is cut off and closed midway. At this time, since the volume of the air passage from the closed portion to the warm air unit 7 is small, the air passage 1
5 Inside air pressure rapidly increases and the air volume decreases extremely. As a result, the temperature of the blown hot air rises rapidly,
A temperature detecting means provided inside the warm air unit 7 detects an abnormal temperature.

Due to the air passage blockage due to the human body load, warm air does not flow to the leeward side of the air passage 15 and the blower bag 1
No warm air is released to the inside of 4, and the warm air does not hit the human body. The hot air blocking performance and the temperature rise response performance in the hot air unit 7 are higher as the air permeability of the cloth forming the air passage 15 is smaller.

As a result, it is possible to save the troublesome and frequent setting for each use, and to avoid the dehydration symptom and the low temperature burn even if the person goes to bed during operation, and to ensure the safety. it can.

Even if a person sleeps or sits on the bed and the thickness of the mattress expands or contracts, the blow-out port 12 is projected and is fastened to the duct 9 at its tip. It does not come off easily, and even if it is permanently installed on the mattress, stable air blowing is possible.

Further, since the tip end of the air passage 15 is sewn to the lower cloth 18, the sewn portion will not be scraped off by abrasion due to turning over, and the blower bag 14 will not be inflated.

Further, the air inlet 1 is connected to the air passage 1
The sewing process is simple and simple because it is made of a single tubular material over the entire length of the air passage 15 from the tip of the blow-in port 12 by folding it to the 5 side and sewing the folded portion around the entire circumference. At the same time, the number of sewn areas is reduced and durability performance is significantly improved.

With this structure, the sewn portion with the upper cloth 17 and the lower cloth 18 of the blow-in port 12 and the air passage 15 is two.
Since it becomes heavy, the durability of the sewing area is improved and hot air does not leak. As a result, even if a high internal pressure is repeatedly applied when the human body is occluded, the obstruction responsiveness does not decrease.
