  Conventionally, as this kind of air circulation type bedclothes, there is one described in Patent Document 1. The air circulation type bedding shown in Patent Document 1 wraps a core material with a fabric having a relatively small air permeability and a high heat insulating property, and a blower for supplying air is attached to an air passage formed by the core material. Have a good bed pad.

Japanese Patent Laid-Open No. 11-266968

  However, the air circulation type bedding shown in Patent Document 1 is configured to supply the air in the bedroom as it is to the inside of the bed pad, and the sleeping person and the inside of the bed pad are separated by a highly heat insulating fabric. Therefore, there is a problem that the dehumidifying effect is not sufficient.

  Therefore, in view of the above-described problems, an object of the present invention is to provide an air circulation type bedclothing that can obtain a sufficient dehumidifying effect.

  The means taken to solve the above problems are a bed pad that is placed on the upper surface in the vertical direction of the mattress placed on the bed and sleeps and has an air flow passage inside, and inhales air in the bedroom. The dehumidifying fan unit for adjusting the predetermined humidity and allowing air of a predetermined humidity to flow into the bed pad, and connecting the dehumidifying fan unit and the bed pad to connect the dehumidifying fan unit to the bed pad with a predetermined humidity. In the air circulation type bedclothing provided with a duct for allowing air to flow in and a control device for controlling the operation of the dehumidifying blower unit, the dehumidifying blower unit is configured to receive the inflow air by a dehumidifier having a base material coated with a moisture adsorbent. Is dehumidified to a predetermined humidity, and air of a predetermined humidity is discharged toward a sleeping person from a plurality of air discharge ports formed in the bed pad, and the bed pad is discharged. There when not being used for sleeping, the dehumidifier is heated to evaporate the adsorbed water, air-flow insole bedding to restore the dehumidification capacity of the dehumidifier.

  In this case, when the predetermined time (1 to 2 hours) has elapsed from the start of going to bed, the control device is preferably controlled so that the dehumidifying blower unit is deactivated.

  The “vertical direction” means a direction “perpendicular” to the horizontal plane on which the bed is installed. The same applies hereinafter.

  According to the present invention, the air flowing into the bed pad is adjusted to a predetermined humidity before inflow, and the air adjusted to the predetermined humidity is provided from a plurality of air discharge ports provided on the upper surface in the vertical direction of the bed pad. Since it is released to the outside and the air directly touches the sleeping person, a sufficient dehumidifying effect is obtained.

  In this case, if the dehumidification is limited to a predetermined time (1 to 2 hours) from the start of bedtime where the sweating amount is the largest, the operation cost can be reduced as compared with the continuous dehumidification.

It is a top view which shows that a sleeping person is lying on the air circulation type bedclothing concerning the present invention. It is A view side view in FIG. It is the top view which showed the detail of the air circulation type bedding which concerns on this invention. It is AA sectional drawing in FIG. It is a perspective view which shows a dehumidifier. It is a graph which shows the operation pattern of the air circulation type bedclothing concerning the present invention.

  Hereinafter, an air circulation type bedding 4 according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the mattress 3 is placed on the frame 2 a of the bed 2, and the bed pad 11 is placed on the upper surface (vertical upper surface) 3 a of the mattress 3. The bed pad 11 is placed so that its four sides overlap with the four sides of the upper surface 3 a of the mattress 3. Therefore, the area of the bed pad 11 is substantially the same as the area of the upper surface 3 a of the mattress 3.

  FIGS. 1 and 2 show a sleeper lying on his / her back in the longitudinal direction of the bed pad 11. In this state, at least one of the sleeping person's back, waist, and buttocks overlaps the plurality of air discharge ports 11 b formed on the upper surface 11 a of the bed pad 11.

  As shown in FIGS. 1 and 2, the bed pad 11 has a flat rectangular parallelepiped shape, and an air inlet 11d for introducing air of a predetermined humidity into the bed pad 11 is provided on the side surface 11c. Yes. The air inlet 11 d is connected to the dehumidifying blower unit 13 by a duct 12. In the present embodiment, the air inlet 11d is provided on the side surface 11c, but it may be provided on the bed pad 11 on the bedside 11e on the foot side 11e.

As shown in FIG. 3, in the dehumidifying blower unit 13, the blower fan 14 sucks air from the air inlet 13 a through the filter 15, and a moisture adsorbent such as sodium polyacrylate is applied to the air as a base material. The dehumidifier 16 is brought into contact with the dehumidified air to obtain a predetermined humidity of air. The humidity of the dehumidified air is desirably 50 to 55% when the blowing rate is 15 m ³ . Thereafter, air is introduced into the air inlet 11d from the air outlet 13b through the duct 12, and the air is sent into the bed pad 11 from the air inlet 11d. When the bed pad 11 is not used for sleeping, the heater 17 in close contact with the housing 16a of the dehumidifier 16 heats the dehumidifier 16 to evaporate the adsorbed water, thereby recovering the dehumidifying ability of the dehumidifier 16. Let The operation pattern for restoring the dehumidifying ability is referred to as “regeneration mode”.

  As shown in FIG. 5, the base material 16b of the dehumidifier 16 is formed by laminating plate members having a triangular wave cross section made of an aluminum alloy or the like, and a triangular columnar cavity serves as an air passage 16c. As described above, the dehumidifier 16 is configured by applying the moisture adsorbent 16d such as sodium polyacrylate to the equipment 16b. In addition, the cross-sectional shape of the laminated plate material may be a honeycomb shape or a rectangular shape.

  Since the temperature rises when the moisture adsorbent 16d adsorbs moisture, a cooling device 18 is provided in the dehumidifier 16 as shown in FIG.

  As shown in FIG. 4, the bed pad 11 is composed of an upper cover fabric 11f, a lower cover fabric 11g, and a cover side fabric 11h, and the inside is hollow. The cavity is filled with a solid mesh (air flow passage) 11i. The cover lower fabric 11g and the cover side fabric 11h are made of polyurethane, polyester, or the like. The cover upper fabric 11f is a three-dimensional mesh that is finer than the three-dimensional mesh filled inside. Air of a predetermined humidity flowing in from the air inlet 11d circulates through the gap between the three-dimensional mesh 11i inside. However, as shown in FIG. 3, in the bed pad 11 of this embodiment, only the central portion 11j in the longitudinal direction of the bed pad 11 becomes a cavity and is filled with the solid mesh 11i, and the cavity is formed on the head side 11k and the foot side 11m. Rather, these parts are normal padding.

  As shown in FIG. 3, the cover upper fabric 11 f of the bed pad 11 is provided with a plurality of air discharge ports 11 b for discharging air of a predetermined humidity flowing into the bed pad 11 to the outside of the bed pad 11. ing.

  When the sleeping person lies in the longitudinal direction of the bed pad 11, the plurality of air discharge ports 11 b are arranged such that at least one of the back, waist, and buttocks of the bed person overlaps the plurality of air discharge ports 11 b of the bed pad 11. Is formed. Moreover, the air discharge port 11b is formed such that the opening diameter thereof becomes larger as it is closer to the central axis in the longitudinal direction of the bed pad 11, and discharges a larger amount of air to the trunk of the sleeping person.

  A known pressure sensor, biological sensor, weight sensor, switch, or the like can be used to detect whether or not the sleeping person is lying on the bed pad 11. Whether sleep is started while the sleeping person is in a supine state is determined by using sleep start detection means (biological sensor, switch, etc.) that detects a signal (eg, brain wave, pulse, etc.) emitted from the human body. It is possible and detailed description is omitted here.

  Here, the operation pattern of the air circulation type bed 4 will be described.

  As shown in FIG. 6, the control device 7 controls the dehumidifying air blowing unit 13 to operate for a predetermined time (for example, but not limited to 1 to 2 hours) from the start of going to bed with the most sweating amount. . The air blower 14 is controlled by the control device 7 so that the amount of blown air is the largest during dehumidification, and the blown amount is automatically reduced stepwise when the dehumidification is completed. An operation pattern in which the blast volume after dehumidification automatically decreases stepwise is referred to as a “dehumidification / blast mode”. The dehumidifying / air blowing mode is automatically set to the dehumidifying / air blowing mode when the sleeping person gets on the bed pad 11 and starts sleeping, and automatically ends after a predetermined time set by the timer.

As shown in FIG. 6, the time of the dehumidifying / air blowing mode varies depending on the air flow rate, and the air flow rate is large (approximately 15 m ^{3 to} 25 m ³ , preferably 20 m ³ ), medium (approximately 10 m ^{3 to} 20 m ³ , preferably, 15 m ^3), a small (approximately ^{5m 3 ~15m} 3, preferably ^{10 m} 3), the minimum (approximately ^{1 m} 3 through 10m ^3, preferably divided into four to correspond to 5 m ^3). For example, when the air flow rate is large, the dehumidifying air blowing unit 13 operates in a predetermined time T1 (AB in FIG. 6) time dehumidification mode, and then the air flow rate is reduced during the air flow rate to T2 (CD in FIG. 6). ) Operates in time blowing mode. When the amount of air is being blown, the dehumidifying blower unit 13 operates in a predetermined dehumidification mode for T3 (EF in FIG. 6), and thereafter the amount of blown air is reduced to a small amount of air to be T4 (GH in FIG. 6) time. Operates in blow mode. When the air flow rate is small, the dehumidifying air blowing unit 13 operates in a predetermined dehumidifying mode for T5 (IJ in FIG. 6), and then the air flow rate is reduced to the minimum air flow rate for T6 (KL in FIG. 6) time. Operates in blow mode. The minimum air flow corresponds to the above-described regeneration mode. In the present embodiment, when shifting from the dehumidifying mode to the air blowing mode, the air blowing amount is decreased by one step, for example, from large to medium. However, the present invention is not limited to this. For example, it may be decreased by two steps or three steps).

  When a sleeping person wakes up and the air-flowing bedding 4 is not in use, the above-described device is automatically used to detect the load on the bed pad or biological information using a switch or the like by a detecting means such as a sensor. In the regeneration mode, the heater 17 that is in close contact with the housing 16a of the dehumidifier 16 heats the dehumidifier 16 to evaporate the adsorbed water, thereby efficiently recovering the dehumidifying capacity of the dehumidifier 16 even with one dehumidifying blower unit 13. Let When a preset time has elapsed, the playback mode is automatically terminated.

  According to the present embodiment, the air flowing into the bed pad 11 is adjusted to a predetermined humidity before flowing in, and the air is adjusted to the predetermined humidity from the plurality of air discharge ports 11b provided on the upper surface of the bed pad 11. Is released to the outside and the dehumidified air at a predetermined temperature directly touches the sleeping person, so that a sufficient dehumidifying effect is obtained. In this case, it is preferable that the air released toward the sleeping person has an air temperature at which the sleeping person does not catch a cold.

  In addition, since dehumidification is limited to a predetermined time (1 to 2 hours) from the start of going to bed with the highest amount of sweating, the operation cost can be reduced compared to continuous dehumidification.
