The present invention relates to an ecological sleep bedding with ecology consciousness.
In a conventional technology, when a bed is warmed, a warm air is blown into a warm air path between a bedding top cover and a sleeping pad, so that an inside environment is adjusted to a comfortable sleeping condition. After the warm air passes through the warm air path, the warm air is discharged to outside. A heater is provided for warming an external air to a specific temperature. Accordingly, in the conventional technology, energy loss tends to be large, and a large amount of carbon dioxide gas is generated and emitted.
Further, in the conventional technology, it is difficult to use an existing bedding top cover and sleeping pad, and it is necessary to purchase a special top cover and sleeping pad provided with the warm air path. In the conventional technology, a temperature and humidity sensor may be installed in the bedding top cover or the sleeping pad. In this case, when an ailing person or an elderly person who has a difficulty to control an inside temperature even through a remote controller, or a room temperature suddenly drops due to a severe cold wind, it is possible to automatically adjust the inside temperature. However, in an actual case, such a sensor tends to malfunction frequently, thereby making it difficult to maintain the device (refer to Patent References No. 1 to No. 6).

In view of the problems of the conventional technology described above, a first object of the present invention is to provide an ecological sleep bedding capable of using continuously for eight hours for a normal person and twenty four hours for an ailing person. In the first aspect of the present invention, it is possible to reduce carbon dioxide, which is a worldwide common issue of mankind.
Further, a second object of the present invention is to provide an ecological sleep bedding capable of retrofitting to an existing bedding top cover and sleeping pad.
Further, a third object of the present invention is to provide an ecological sleep bedding capable of preventing odd smell and in-house infection due to discharge of urine smell or disease-causing germs together with a warm air into a room when a user uses the ecological sleep bedding at home, or in a hospital or nursery home.
Further, a fourth object of the present invention is to provide an ecological sleep bedding capable of preventing the issues such as difficult maintenance or malfunction of the sensor installed in the bedding top cover or the sleeping pad for automatically adjusting the inside temperature when an ailing person or an elderly person uses the ecological sleep bedding.
Lastly, a fifth object of the present invention is to provide an ecological sleep bedding with ecology consciousness capable of operating with small power consumption, thereby reducing carbon dioxide gas emission.
In order to attain the objects described above, according to the present invention, an ecological sleep bedding includes a fan for circulating a bed inside air between a bedding top cover and a sleeping pad. More specifically, a stereoscopic air passing net is provided for sucking the bed inside air between the bedding top cover and the sleeping pad, and the bed inside air is sucked in an air warming circulator device for circulation through an intake tube and an intake inlet of the air warming circulator device.
In the present invention, a bedding top cover air circulating net is attached to the bedding top cover, and a sleeping pad air circulating net is attached to the sleeping pad. A sleeping pad air circulating cloth covers the sleeping pad air circulating net. Further, the stereoscopic air passing net is disposed between the bedding top cover and the sleeping pad, and is placed on the sleeping pad. The stereoscopic air passing net is connected to the air warming circulator device, so that it is possible to retrofit the ecological sleep bedding to an existing bedding top cover and an existing sleeping pad.
In an embodiment of the present invention, as shown in
An air flow of the air warming circulator device 1 will be explained next with reference to
In the next step, after the air passes through a return path 18, a sterilization lamp 17 shown in
At this moment, a computer controls an adjustment heater 13 and a motor 8 according to the signal from the return sensor 12, so that the temperature and the humidity of the air are adjusted at a specific level, for example, the temperature of 28° C. to 34° C. and the humidity of 30% to 50%. After the temperature and the humidity of the air are adjusted, the air passes through a sleeping pad air outtake outlet 4 and a sleeping pad air outtake tube 24, so that the air returns to be the bed inside air 35 from a sleeping pad air blow cloth 34 through a sleeping pad air passing net 31.
In the embodiment, an intake temperature humidity sensor 43 has a function similar to that of the return sensor 12. Further, after the air flows into a bedding top cover air outtake outlet 6 through the warm air path 14, the air passes through a bedding top cover air outtake tube 23, so that the air returns to be the bed inside air 35 through a bedding top cover air outtake cloth 34 through a bedding top cover air passing net 31. Accordingly, the air is combined with the air flowing from the sleeping pad, thereby creating the comfortable environment.
It is noted that heat of the warm air at the temperature of 32° C. is dissipated from the bedding top cover and the sleeping pad. A human body having a body temperature of 32° C. becomes a heating body, so that the air having a temperature of around 31° C. returns to the intake tube 28 of the air warming circulator device 1 through the stereoscopic air passing net 22. Accordingly, the warm air circulates through the path described above, thereby preserving energy and reducing carbon dioxide emission.
As shown in
In the embodiment, as shown in
In the embodiment, a bedding top cover air blow net 32 or a bedding top cover air outlet attaching cloth 29 shown in
In the embodiment, the bed inside air 35 is circulated as shown in
In the embodiment, as shown in
Further, when the return sensor 12 detects the humidity of the bed inside air 35 higher than 40% by 3% to 5% due to perspiration, the rotation of the motor of 10 w is increased to increase an amount of the air, so that the humidity is maintained at 40%. In the opposite case, the rotation of the motor of 10 w is decreased to decrease an amount of the air, so that the humidity is increased through perspiration.
Further, the intake temperature humidity sensor 43 is disposed in the stereoscopic air passing net 22, and the return sensor 12 is disposed in the return path of the air warming circulator device 1. Accordingly, it is possible to accurately measure and control the temperature of the bed inside air 35, thereby making it possible to solve the problems without malfunction.
As an effect of the first object, as shown in
Further, as shown in
As an effect of the second object, it is possible to retrofit the set of the air warming circulator device 1, the sleeping pad 31, the stereoscopic air passing net 22, and the bedding top cover air outlet attaching cloth 29 shown in
As an effect of the third object, as shown in
As an effect of the fourth object, in the conventional device, a temperature sensor extends from a heater to inside between a top cover and a sleeping pad, so that the heater is controlled through a signal of the temperature sensor. Accordingly, the temperature sensor measures only a temperature or humidity of an air blown from the heater, and it is difficult to measure a temperature of an air inside a bed. On the other hand, in the present invention, the temperature of the bed inside air 35 is measured at the intake inlet 3, so that it is possible to control the temperature of the bed inside air 35 inside the bed.
In the embodiment, the intake temperature humidity sensor 43 may be disposed in the stereoscopic air passing net 22, so that it is possible to quickly detect the temperature and the humidity of the bed inside air 35. Further, it is possible to install the intake temperature humidity sensor 43 at the position at a factory, thereby making it possible to easily install while reducing probability of malfunction.
It is noted that when a person stays at a hotel, the person tends to turn on the air conditioner upon entering a room, and keep the air conditioner on until check-out. When the air warming circulator device 1 is used to maintain the temperature inside the bed, even if the air conditioner is turned off during sleep, a room temperature is maintained 26° C.±3° C. due to the good temperature retention performance. Instead of maintaining the room temperature with the air conditioner of 2.2 kw, it is possible to maintain the comfortable environment inside the bed with the air warming circulator device 1, thereby providing good night sleep, energy conservation, carbon dioxide reduction, and benefit to hotels. Especially, the present invention is beneficial for people in transportation industry, which tends to have short sleep time. Further, if people associated with medical and responsible for a patent life for 24 hours do not sleep well, a serious error may occur. The present invention should be good fit to such people. Further, the present invention can be effectively applied to a patient with bedsores.
