Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric bedding which can dry bedding such as a comforter.

[0002]

2. Description of the Related Art Conventionally, a drying device of this type has a structure as shown in FIGS.

That is, the user himself sandwiches the air-blowing mat 3 of the bag-shaped container between the mattress 1 and the comforter 2, and connects the air-blowing hole 4 and the air-passage 5 provided at the end of the air-blowing mat 3 with each other, and further the electricity is supplied. The warm air generating device 6 having a heater is communicated through the air passage 5 to send the warm air to the blower mat 3, and the warm air is blown into the bed through the grain of the bag-shaped container of the blower mat 3 to lay the futon. Both the 1 and the betting set 2 are 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. Because 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 circulates due to the wide hot air passage, which causes responsiveness. There was a problem that it could not be said to be a good detection means.

Further, since the blower mat 3 has a structure for blowing air by utilizing the air permeability of the cloth, the cloth may be clogged due to dust in the atmosphere and the cloth must be frequently washed. Therefore, many ventilation holes having a diameter of about 3 mm were provided in the blower mat 3, and attempts were made to prevent the clogging, but the productivity was poor and a problem was encountered in putting it into practical use.

[0007] Therefore, the present invention provides an electric bedding with a drying function, which can save the trouble of attaching and detaching each use and can evenly dry the whole bedding without causing clogging and having a high safety. Has an aim.

[0008]

In order to achieve the above object, the electric bedding of the present invention includes a blower, a heater, and a detection means for detecting the temperature of the hot air, and a warm air unit attached at substantially the center. The blower mat includes a blower mat having an annular air passage that blows warm air from a ventilation hole provided on a surface of the warm air unit, and a duct that connects the blower mat and the warm air unit to each other. Forms an annular air passage that communicates with the duct, provides the ventilation hole in the inner peripheral portion of the annular air passage, provides a cross air passage that communicates with the duct and crosses the blower mat, and The configuration is such that the end portion communicates with the annular air passage.

[0009]

According to the present invention, with the above-described structure, the warm air flows into the blower mat, and the warm air blown out from the ventilation holes on the surface is collected inside the annular air passage so that the bedclothes can be dried uniformly in the used state. At the same time, it is possible to prevent a decrease in performance due to clogging, and to block the warm air passage while sleeping by the cross air passage, there is no adverse effect of warm air on the human body, and an abnormal rise in warm air temperature can be detected with good response.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the electric bedding according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 7 denotes a 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 at substantially the center of its side surface and fixed on a bed mattress 10 via a duct 9. The blower mat 11 is configured to communicate with warm air.

2 and 3 are a partially cutaway sectional view from the foot and a side sectional view of the partially cutaway in the embodiment. The blower mat 11 has an upper cloth 12 and a lower cloth 13 sewn on the outer periphery thereof with a hem cloth 14, and the upper cloth so that a transverse air passage 15 having a width of 200 mm is formed at the center of the long side of the blower mat 11. 12 and the lower cloth 13 are sewn, and the cross air passage 1
A duct 9 that guides the warm air of the warm air unit 7 is connected to the end of 5, and the other end is sewn with an upper cloth 12 and a lower cloth 13 with a certain distance from the outer circumference of the blower mat 11. It is communicated with the inner peripheral portion of the annular air passage 16. Further, the bed mattress 10 and the wrapping cloth 17 serving as a fixing means are provided at the upper and lower edges of the lower cloth 13. Reference numeral 18 is a hook for attaching the warm air unit 7 to the bed 8.

FIG. 4 is a top view, in which an annular air passage 16 is provided symmetrically with respect to the transverse air passage 15 in the vertical direction.
A plurality of vent holes 19 of 50 mm × 10 mm square are provided from the inside of the surface on the upper surface side of 6. The alternate long and short dash line in the figure is the hot air inflow line.

Next, the operation of the structure of this embodiment will be described. The warm air from the warm air unit 7 attached to the side surface of the bed 8 passes through the duct 9 and is guided to the blower mat 11 fixed on the bed mattress 10 with the cloth 17 and blown out to the cross wind passage 15 and the cross wind passage 15 thereof. As the pressure increases through the annular air passage 16 at the end of the, the cross air passage 15 and the annular air passage 16 swell and hot air is blown out from the ventilation holes 19, and the bed pad, the sheets, and the comforter are hung, and as shown in FIG. As described above, a space a in which warm air is collected is formed, and uniform futon (bedding) can be dried from the feet to the chest. Standard bed pad,
Required static pressure when using sheets and comforters is about 8 mmA
q, the air volume is about 0.4 m ³ / min, and in the small and thin warm air unit 7 that can be attached to the side surface of the bed 8, this can be achieved when the distance from the cross air passage 15 of the blower mat 11 is large. This is because the pressure loss is short and the pressure loss can be reduced. Further, unlike the conventional method utilizing the air permeability of the cloth, the air holes 19 of 50 mm × 10 mm are provided, so that clogging does not occur.

From a safety point of view, if a person sleeps in a driving state, he or she will block 100% of the cross air passage 15 located at the center and stop warm air in this cross air passage 15. The warm air is not emitted from the ventilation hole 19 of the annular air passage 16 downstream of the cross air passage 15, and therefore the human body is not hit by the warm air, and the abnormal temperature rise is well responded by the detection means of the warm air unit 7. Can be detected.

As a result, the blower mat 11 is not clogged and it is not necessary to wash it. In addition, there is no inconvenience of drying the futon while performing complicated and frequent setting every use.

Further, by forming the space a in which the warm air is collected by the annular air passage 16, the warm air is agitated in this space a, and uniform futon (bedding) drying can be achieved from the feet to the chest.

Further, by providing the cross air passage 15 at the center of the long side portion of the air blowing mat 11, even if the user sleeps during operation, the air passage for warm air is blocked and the warm air is not released. Safety can be secured without adversely affecting the human body.

[0018]

As described above, according to the electric bedding of the present invention, the blower mat is composed of the transverse air passage and the annular air passage, and the air passage is provided on the surface of the annular air passage to provide the warm air unit and the air blower mat. By fixing each to each, you can save the trouble of attaching and removing each use, and you can evenly dry the entire bedding without causing clogging, and in the case of going to bed during an emergency Is a safe and easy-to-use product that does not adversely affect the human body.
