Last four in the above form is the upper and lower bound that air leaves the speed and the difference in air temperature on fibre surface, and they have provided the scope that can produce those numerical value of just right clean air embracing layer with the system of Figure 11-13 and 18-20.When the speed of leaving the fibre surface at air is lower than 30 feet per minute clocks (9.14 meters/minute), the size of clean air embracing layer is reduced from the extraneous air stream of for example HVAC of family (heating, ventilation and cooling) system.The upper limit of air velocity scope is based on such air stream, is exactly that its intensity should not make the people in sleep feel under the weather.Since the degree of feeling under the weather be vary with each individual and be the viewpoint that depends on everyone, the upper limit of air velocity can change.But research shows: the air velocity that is no more than 60 feet per minute clocks (18.28 meters/minute) is actually imperceptible, for most of people, can not cause uncomfortable sensation.
Also have, the induction system 10 that is used for the bedroom environment should be designed to is quiet as far as possible.A way of the noise of reduction system 10 is that appropriate design pipeline 16 reduces noise.This representation of concept is in Fig. 3, and wherein conduit 30a comprises a noise reduction section 31, and it is made of the sound-absorbing material parcel permeable fibre of sound.Fibre can be nylon or the polythene material that for example wire drawing is twisted flax fibers and woven.Sound-absorbing material can be for example felt, wool or foamed material.Also can be with other fibre and sound-absorbing material.
The position of represented noise reduction section 31 only is exemplary.Also can be placed on other position to noise reduction section 31, comprise being placed in conduit 30b and/or the 30c.And, a more than noise reduction section can be set.
Also have, can further reduce noise with low noise blowing plant 12.
In addition, even the inventor has been found that the temperature difference of the air that is transferred is very little, also can make the profile of clean air of the head that is spread in the people and shoulder or the size and the shape of embracing layer that very big difference is arranged.The thermograde that nature is all arranged in each room almost, the local temperature near the floor is low more.In many rooms, the temperature difference of 1 to 4 (0.56 to 2.24 ℃) is arranged down with bed on the bed.
Have been found that: when the temperature of the air that is transferred was no more than 2 °F (1.12 ℃) and is no more than 1 °F (0.56 ℃) than environment temperature height than environment temperature is low, the embracing layer of clean air can keep can be by size that is subjected to and shape.If the temperature of the air that is transferred is lower than this scope, it is too low that the height of clean air embracing layer can become.And if the temperature of the air that is transferred is higher than this scope, then the clean air embracing layer can raise and along continuous straight runs skims over the user.
Figure 24 has described a curve map, and it expresses all temps state with the system of Figure 11-13 and 18-20.This figure is the side view of system with respect to bed, and transverse arm is positioned at bed surface top about 17 inches (0.432 meters) and locates.Those curve tables are shown in clean air embracing layer under the specific temperature difference and border without the surrounding air that purifies.The upper and lower border of the embracing layer that forms when the temperature difference of air that is transferred and surrounding air is+1 (+0.56 ℃) is represented with the dotted line of arrow indication.The coboundary of the embracing layer that forms when being respectively-1 (0.56 ℃) and-2 (1.12 ℃) in temperature difference is also represented with the line of arrow indication.For the temperature difference of 0 (0 ℃) ,-1 (0.56 ℃) and-2 (1.12 ℃), the lower boundary of each embracing layer is the surface of mattress and pillow.This figure shows: when the temperature difference that increases thereby make air that transverse arm blows out and surrounding air in the temperature of the air that comes out from transverse arm also increases, and the height reduction of clean air embracing layer.
In this system, because the compression of blowing plant, the temperature of the air that is transferred may raise 1 °F, and if the motor of blowing plant is to be in the air stream, temperature may raise 2 to 4 (1.12 ℃ to 2.24 ℃).According to used induction system, the rising of temperature has be beneficial to or be harmful to the clean air embracing layer that forms around people's head and shoulder, therefore needs to consider the rising of temperature.So, must consider that the configuration of used air conveying system can influence air themperature, in the hope of reaching best performance.
For the such induction system that hardens and be integrated with Bed cushion of the induction system shown in the image pattern 2 24, can believe that the temperature of the air that is transferred should be as far as possible near the environment temperature at induction system place, temperature difference should be within ± 2 °F (± 1.12 ℃).So the motor of blowing plant can be selected and be designed to be able to the air that is drawn into from the floor is added heat a bit, for example make 1 ° to 2 ° degree of its temperature rising.Temperature by the air that keeps being transferred can make the best that is shaped as of clean air embracing layer near ambient air temperature.
Blow to the induction system of people's head downwards for the top of the head that is designed to be installed in the people and the air that is transferred, system 74 for example shown in Figure 8, blowing plant and motor should be designed to the air that is drawn into from the floor almost or not heating.As a result, the colder air on the floor will be transported to the top and the downward head movement to the people of people's head, because the air colder than ambient air can be to sinking.Colder air helps to produce desirable clean air embracing layer to the motion of people's head, and can reduce the power consumption of motor.
Above explanation, example and data are given design of the present invention, manufacturing and should be used as a complete description.Owing to can also make many embodiment within the spirit and scope of the present invention, so scope of the present invention is decided by the appended claim in back.
