Embodiment
Fig. 1 shows the structure of the air-conditioning bed 100 according to the present invention. As shown in Figure 1, air-conditioning bed 100 comprises the bedstead 1 extended in the horizontal direction. Mattress 30 is placed and is supported on horizontal bedstead 1. Mattress 30 is associated with the first air-conditioning system, so that by the region of transfer of air above mattress 30 through regulating, thus above mattress 30, define conditioned area 9. In other words, mattress 30 is formed so-called " air-conditioning bed mattress ". In a preferred embodiment, mattress 30 forms the conditioned area 9 of a base closed together with covering the blanket 5 of the sleep person's health slept on bed 100.
In most of the cases, the head of sleep person can not be covered by blanket 5. As a result, the cool or warm air in conditioned area 9 can not be transported to the region near sleep person's head. For this reason, the head panel 20 of the end being arranged on bedstead 1 is also comprised according to the air-conditioning bed 100 of the present invention. Head panel 20 is associated with the 2nd air-conditioning system, so that transmitting warm or cool air according to specific season to the space near sleep person's head. Therefore, the head panel 20 of bed 100 together with mattress 30 for sleep person provides a cosy region. Preferably, the first and second air-conditioning systems provide the temperature of air of institute and amount to be decided by the healthy state of expectation thermal comfort index (PMV) and sleep person.
According to an embodiment, the first air-conditioning system being associated with mattress 30 and the 2nd air-conditioning system being associated with head panel 20 include electrothermal module 40, to provide heating or refrigerating function. Electrothermal module 40 by for those of skill in the art known, produce cool or warm air as the thermoelectric effect of temperature contrast and the direct conversion of voltage. It is omitted here its principle and structure for simplicity's sake. It should be appreciated that the first and second air-conditioning systems also can comprise other forms of air-conditioning unit.
Fig. 2 and Fig. 3 each displays side-view and the frontview of electrothermal module 40. As shown, electrothermal module 40 comprises the thermounit 41 with two sidepieces, the blower fan 42 being connected with thermounit 41 and control unit (not shown). When applying specific voltage to thermounit 41, owing to thermoelectric effect produces temperature contrast between two sidepieces. Heat/cool flow of air that blower fan 42 produces near two sidepieces for blowing, to be delivered to the region near sleep person by specific airflow as required.
In one embodiment, the electric power comprising thermounit 41, power supply and pilot circuit of the first air-conditioning system and mechanical part are arranged in mattress 30. Showing this structure in FIG, it contributes to the space occupied by minimumization, and contributes to as bed provides good mobility.
However, it should be noted that these electric power and mechanical part keep running and vibrations in operation, therefore can produce sizable for noise completely uncomfortable sleep person. Therefore, in a useful embodiment, the electric power of the first air-conditioning system and mechanical part are arranged in the wall close with bed, or are placed on the floor below bed. In other words, electric power is placed in the way of directly not contacting with mattress 30 with mechanical part, so that ensureing quiet environment at night. It should be appreciated that the electric power of the 2nd air-conditioning system and mechanical part also can be placed similarly.
Returning to Fig. 1, according to an embodiment, mattress 30 comprises mattress body 2 and mattress surface layer 3. Mattress surface layer 3 has perforation to allow air to flow into and to flow out conditioned area 9. Air passageways 60 is provided, so that making electrothermal module 40 communicate with the hole in mattress surface layer 3 in mattress body 2. In an embodiment, air passageways 60 is the form of flexible tubing. Preferably, the hole in mattress surface layer 3 has valve, and it can close closed pore as required and optionally.
In a preferred embodiment, between mattress body 2 and mattress surface layer 3, it is provided with gas cloud 22. Gas cloud 22 can be used as the intermediate storage station between air passageways 60 and mattress surface layer 3, to store cool air or warm air in there, and can make being evenly distributed of flow of air simultaneously. When being provided with gas cloud 22, it is possible to reduce the quantity of air passageways, so that simplifying the structure of mattress 30 and reducing productive expense. Gas cloud 22 also can in response to external pressure so that when sleep person lies on mattress, automatic ground-to-air gas-bearing formation 22 is exerted pressure by its weight, thus is released from mattress 30 by cool/warm air, and the arrival conditioned area, hole 9 in mattress surface layer 3.
Generally, in summer, fresh room air is inhaled in electrothermal module 40 and lowers the temperature. This air absorbs the heat from sleep person's health in conditioned area 9 and is discharged in surrounding environment after heating. When sleep person is stamped blanket, warm air is not easy to overflow through blanket. In addition, when, even during midsummer, the window in room is opened, room air is relatively high, and such as, time more than 30 DEG C, electrothermal module 40 needs repeatability cooling room air to required temperature, and this can cause very big energy expenditure.
Therefore, in the present invention, air passageways 60 is further divided into two groups, i.e. air-supply passage and return air channel. Meanwhile, the hole in mattress surface layer 3 is also divided into two groups, and one group is connected with air-supply passage and another group is connected with return air channel. Such as, in summer, by air-supply passage, the first group hole of the cool air from electrothermal module 40 in mattress surface layer 3 is assigned in conditioned area 9. In addition, by return air channel, the two group hole of the air with higher temperature from conditioned area 9 in mattress surface layer 3 is extracted out, then return electrothermal module 40.
According to the present invention, the return air from conditioned area 9 is cooled slightly again, is such as cooled several degrees Celsius, is then again sent in conditioned area 9. When room temperature is higher than return air temperature, the cooling again of return air contributes to minimum power consumption. On the other hand, when return air temperature is approximately equal with room temperature, the 2nd air-conditioning system of head panel 20 is run in the pattern providing 100% fresh room air, that is, room air is reduced to the temperature of required such as 26 DEG C all the time. Therefore, obtaining a cosy region around sleep person, energy expenditure remains low simultaneously. In the case, it is not necessary that cool the return air from conditioned area 9.
According to the present invention, two control units are adopted to control the operation of air-conditioning bed 100. 2nd control unit is used for head panel 20, and adjustable is blown the contact velocity of sleep person's head and temperature, and the instruction that this adjustment is preferably inputted by interactive interface based on user carries out. In an embodiment, accurately control air velocity so that being remained between 0.1m/s to 0.2m/s by the contact velocity of air to head.
First control unit is used for mattress 30. It is according to the temperature of the requirement of user adjustment conditioned area 9 with from the air-supply flow rate of mattress 30. First control unit can comprise the infrared sensor 70 of the temperature for detecting conditioned area 9 being arranged in mattress surface layer 3. In an embodiment, in summer and winter, the temperature of conditioned area 9 is remained on around 26 DEG C, simultaneously wind pushing temperature is arranged on 24 DEG C in summer and is arranged on 28 DEG C in winter. Air-supply speed through hole is arranged on 20l/s.
By the flow of air of 20l/s air-supply speed and be the temperature head of 2 DEG C between air-supply and return air, it is possible to dissipating the heat of 50W if estimating sleep person, so needing at least 60 flexible air passagewayss for single bed, every root has the diameter of 3cm. Certainly, can free adjustment air passageways quantity and arrange to meet the different needs. In addition, with the use of the valve optionally closing closed pore, the air distribution from mattress surface layer 3 can be adjusted further.
Fig. 4 shows the change of the temperature the whole length of one's sleep (from point at 11 in evening to morning 7) conditioned area 9. As can be seen from Figure, sleep start and at the end of, the temperature in conditioned area 9 is lower, but higher in the time-division at midnight. Responsively, at whole night, the temperature of air-supply and flow velocity should not be constant. In other words, between sleep period, it is preferable to temperature and air velocity have change, this realizes by the first and second control units. It should be noted that this curve should be adjusted individually, to mate mutually from the health of different sleep person, age and sex etc.
The temperature of traditional air conditioner device controls mainly based on the thermostatted of machine inside. In most of the cases, bed all can not very be abutted against and is bordering on air-conditioning and places. As a result, air-conditioning plant is difficult to and almost can not predict and even control the air themperature near sleep person, particularly when sleep person is stamped blanket. With the use of the air-conditioning bed according to the present invention, it is possible to accurately measure and control the air themperature of sleep person's health and head.
It is obvious to a person skilled in the art that, can carry out in the system of the present invention improving or changing and do not deviate the spirit or scope of the present invention. The invention is intended to cover all improvement being in right and change and their equivalents.
