Abstract

PURPOSE:To offer a comfortable electric bedclothes which can be used to dry any kind of bed quilt uniformly without such a laborious work that an air blow mat is laid when a conventional bedclothes dryer is used, and a clogging problem. CONSTITUTION:A warm-air unit 7 with a built-in heater and fan communicates with an air blow bag 9 having a number of air outlets 17 on the surface via a duct 8 and a warm-air inlet 15 which are mounted at the middle of the side face. An air blow bag attaching cover 11 which is sewed in a box-like shape so as to envelop a bed mattress 11 is attached on the bottom face of the air blow bag 9 to unite them into a piece. In addition, the air blow bag 9 is made from a woven fabric which contains cotton fiber at least 30% and undergoes a filling-up process.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to bedding for beds and the like, and relates to an electric bedding for drying bedding such as comforters on beds.

[0002]

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

That is, the user himself sandwiches the cloth-made blower mat 3 between the mattress 1 and the comforter 2, and connects the blower hole 4 and the ventilation passage 5 provided at the end of the blower mat 3 with each other, and further, the electric heater. The warm air generating device 6 having the air passage 5 communicates with the blower mat 3 to send the warm air to the blower mat 3, and the warm air is blown into the bed through the cloth to dry the mattress 1 and the comforter 2. I am supposed to do it.

[0004]

However, in such a conventional structure, the blower mat 3 is inserted into the center of the bedding and wrinkles are extended, and the ventilation passage 5 and the warm air generator 6 are set. It was necessary to carry out a complicated operation.

In addition, when the bed is used, there is a problem that warm air does not reach the end of the blower mat 3 by making the bed.

Further, since the blower mat 3 has a structure in which air is blown by utilizing the air permeability of the cloth, clogging occurs due to dust in the air and the blower mat 3 must be washed fairly frequently. There was also the problem of not becoming.

Therefore, according to the present invention, it is not necessary to lay the air-blowing mat one by one when using the air-blowing mat, the air-blowing bag can be attached to the bedding such as a bed mattress, and the entire bedding can be dried uniformly without causing clogging. Can be made

It is an object of the present invention to appropriately dissipate moisture from a sleeping person due to sweating or evaporation to realize a comfortable in-bed environment.

[0009]

To achieve the above object, the present invention comprises a warm air unit having a blower and a heater, and a large number of ventilation holes provided on the surface for receiving the wind from the warm air unit. A blower bag for blowing out warm air is provided, and the blower bag is made of a cloth obtained by crushing a woven fabric containing at least 30% of cotton fibers.

[0010]

With the above structure, the electric bedding of the present invention easily bulges due to the internal pressure of the blower bag as the warm air flows into the blower bag communicating with the warm air unit, and the warm air is uniformly blown through the ventilation holes on the surface. Since it is blown out to the upper surface, it is possible to dry the bedding such as a comforter hanging on the bed in a used state. In addition, since the blower bag is made of a cloth obtained by crushing a woven fabric containing at least 30% of cotton fibers, it is possible to sufficiently dissipate water from the human body.

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

In FIG. 2, reference numeral 7 denotes a warm air unit having a heater and a blower built therein, which is constructed so that the blower bag 9 and the warm air communicate with each other through a duct 8. A bed mattress 10 is wrapped around the lower surface of the blower bag 9 to blow the blower bag 9
The blower bag attachment cover 11 for firmly attaching the to the bed mattress 10 is sewn and integrally formed.

FIG. 1 is a sectional view of the embodiment. In the blower bag 9, an upper cloth 12 and a lower cloth 13 are sewn on the outer peripheral portion thereof with a hem cloth 14, and a warm air inlet 15 and the duct 8 are joined to communicate with the warm air unit 7. .. Further, the blower bag mounting cover 11 is sewn and integrally joined to the lower fabric 13 from the outer peripheral portion thereof, and the blower bag mounting cover 11 is sewn in a box shape so as to wrap the bed mattress 10. A rubber band 16 is sewn on the lower end of the entire circumference. With this structure, the bed mattress 10 can be firmly attached. Further, the upper fabric 12 is provided with a large number of ventilation holes 17 having a diameter of 3 mm, and has a structure in which warm air from the warm air inlet 15 is blown to the upper surface.
In addition, 18 is a bed main body and 19 is a headboard.

The upper fabric 12 and the lower fabric 13 are high-density cotton fabrics that are crushed by a calendar, and subjected to a down proofing process which is generally used for the side of a down duvet. As a result of the experiments so far, when the air permeability is not less than 1.0 cm ² / cm ² / sec as measured by the JIS L 1096 Frazier type method, the amount of air leaking from the fabric increases and the blower bag 9 does not fully expand. It was found that uniform air flow was not possible. Furthermore, JI
Approximately 50 in moisture permeability measurement by SL 1099 A-1 method
It was also found that when the moisture permeability of 00 g / m ² · 24H or more is not present, the ventilation bag 9 is constructed so that the moisture dissipation becomes extremely bad and the comfort in the bed is affected. When 30% or more of cotton fiber is contained, due to its natural moisture absorption and release,
The above-mentioned moisture permeability is secured.

With this structure, the warm air discharged from the warm air unit 7 passes through the duct 8 and is blown into the blower bag 9. As the pressure inside the bag increases, the blower bag 9 swells and a warm air passage can be secured up to both ends of the foot and chest, and the warm air is blown out uniformly from the ventilation hole 17. The static operating pressure when a standard bed pad, sheets and comforter were hung was about 15 mmAq, and uniform comforter drying could be achieved with a thin compact type fan that can be attached to the side surface of the bed mattress 10. Further, unlike the conventional method utilizing the air permeability of the cloth, the vent hole 17 having a diameter of 3 mm is provided, so that clogging does not occur.

[0016]

The present invention is provided with a warm air unit having a blower and a heater built therein, and a blower bag which receives warm air from the warm air unit and blows warm air through a plurality of ventilation holes provided on the surface. The bag has the following effects when it is made of a cloth obtained by crushing a woven fabric containing at least 30% of cotton fibers. (1) Since the ventilation bag is provided with ventilation holes, the ventilation bag does not become clogged and there is no need to wash the ventilation bag, so it is convenient and can be continuously used while installed. (2) The inner pressure of the blower bag can be increased to smoothly blow off and dry, and at the same time, the moisture of perspiration and vaporization from the human body can be sufficiently dissipated to provide comfortable bedding. (3) By applying the blinding process, even if the ventilation hole is provided, that portion is not easily frayed, and the ventilation performance is stable.
