Description

BACKGROUND OF THE INVENTION The present invention relates to a lockable and air-conditioned air-conditioning bed, in particular a resting, thermo-medical berth surrounded on all sides by enclosing elements, a reclining bed as a lower limiting member, , connecting elements and ducts connecting the air conditioning unit to the bed compartment, air handling, adjusting and actuating means.

The structure described in the preamble is known from Hungarian Patent Application No. 206,609. The experience gained during the manufacture or use of this structure shows that the description of the present invention did not fully take into account the aspects of modern large-scale production technology and the interest of the user in the price of the bed structure. The feature of the bed type described below is that the air-conditioning unit can be assembled according to the particular climate, so we use the term "air-bed" to distinguish it from Hungarian Patent No. 206,609.

The purpose of the climate bed is to ensure a peaceful, deep and regenerative rest of the human being in all geographical areas with extreme climates. In cold climates, as well as in the humid tropics or in hot climates in the south. However, it has become clear that in different geographically different areas, it is economical to operate differently designed climatic beds. In the southern states, the emphasis is on cooling the air. In the harsh Arctic climate, especially heating is required. It is common in cold climates that the temperature of the air does not exceed 25 ° C in summer, so there is no need to install a cooling unit, which is otherwise included in the climate bed. Therefore, in cold climates, it is advisable to create a so-called "northern type" air-conditioning bed, whereby a fan can be used to replace the air in the bed space in case of overheating or to reduce enriched humidity. This saves the cost of a refrigerator, reducing the cost of producing an air conditioner, but also improving the efficiency of cooling by changing the air in the bed. On the other hand, in hot and humid environments, a refrigerator-built air conditioner is needed to provide a comfortable bed climate, as the "southern" air conditioner needs to perform both cooling and air drying. In view of the above, it is expedient to construct the air conditioning unit of the air bed so that the cooling block of the southern type bed can be replaced by a fan unit of the same external size, so that it can be easily changed to the northern type. Thus, a basic unit comprising a heating block that can be used for two different climates can be made, which can be supplied with a refrigerator or ventilator adapter as required by the user.

Above the air bed mattress, a semi-cylindrical shell vault, known as a bed cover, encloses the bed space. In order to maintain the temperature of the covered bed space, the bed cover should be made of layers of good heat insulation material. Considering the aspects of large-scale production technology, it is expedient to make the bedspread with a limited number of production tools or materials. This is accomplished by wrapping the polyester-terry web as a heat-insulating material between two layers of impregnated fabric, and attaching the resulting sheathing sheet to circular aluminum rod supports, which are bent to conform to the curvature of the semi-cylindrical bedspread. The tent-like tensioning bed cover aluminum rod support members are sewn onto strands of tape about 3 cm wide to support the weight of the bed cover. The above-described bedspread can be made with much less labor than the invention of the above-mentioned Hungarian Patent Application 206609, since only manufacturing and sewing operations can be accomplished and the material utilization is better than that of the accordion-like blanket, which makes it cheaper.

It is preferable to build the air conditioning unit cooling unit from Peltier elements instead of the conventional circulating liquid, environmentally friendly refrigerator. (The phenomenon known as Peltier Effect in physics utilizes the cold formed by the direct current applied at two soldering points of metal to the refrigerator.) The advantage of the electronic cooling mode over the absorption refrigerator is that it has a small, long life without environmentally polluting refrigerant. Another advantage of using the Peltier-type refrigerator is that it is not position-dependent, so it can be used not only in a vertical position, so it can be mounted under the bottom of the air-bed, even in a lying position.

Built with an air conditioning unit under the bed base, the recirculated air passes through the ducts to the bed space above the mattress.

The electric air handling units of the air conditioner can be operated partly by controls or partly by manual switching. The AHUs are equipped with a heating, cooling thermostat and hygrostat in the circuit of the air handling units. These controls are used to set the desired values for the basic temperature and humidity of the bed. During practical use, it may also be necessary to create a non-standard air condition in the bed, which can be achieved by manual control. For this purpose, a control panel is arranged along the headline line, on which circuit switches of the heating, cooling, air-drying units of the headrest and the temperature display are mounted.

Therefore, it is an object of the present invention to overcome the drawbacks of the above known solution

- for cold climates, adapted to the climate, it is possible to replace the refrigerator with a cheaper ventilation unit,

- the cost of manufacture is minimized by the rational choice of bedding material and the simple construction of the bedding material,

- by installing a Peltier refrigerator, the air conditioner can be mounted under the bottom of the air bed, thereby restoring the bed to the character of the furniture,

- the use of a control panel makes it possible to manually regulate the bedside air condition according to the actual need.

1-4. Fig. 4A shows a bed with an air conditioner integrated in a cabinet-shaped endrest at the foot end of the bed. 1, the bunk bed 3,4 on the bottom 2 of the bed frame 1 and the head section 5 is constructed from the rear support 6 (Figure 2) and the bed cover 7 (Figure 3) so that the elements listed form a closed bed the person lying on the bed. The bed frame 1 is of a similar shape to a standard bed and is made of wood or metal of closed gauge with a frame 9 with a cornice 9 about 12 cm wide above the four legs 8 with two 5 to 5 cm thick polyurethane beds 4 on the bottom. Figure 1). The edges of the lower mattress 3 extend into the coffees formed by the bed sides 8 and the ledges 9, filling them. The upper mattress 4 is placed on the lower mattress 3 and positioned between the two-sided ledges 9 to form the lower boundary plate of the bed C (Fig. 3).

The head 5 of the bed frame 1 is a columnar, textile-covered polyurethane foam having a switch panel 10 at its end. On the footboard 11 of the bed frame 1, two square block recesses 12 are provided for receiving the retaining pins 13 of the end support 6 (Fig. 2). The end support 6 is connected to the electrical network by means of the wire 14, which is connected to the switch panel 10 by the electric wire. The double ledge 9 (Fig. 3) of the bed frame 1 carries the bed cover 7, guided by the protrusion of the mattress 4 from the ledge 9. The bed cover 7 can be connected to the end support 6 by means of a strap (Fig. 2). The fastening strap 16 is a strap made of imitation leather with a flap 17 at the two edges for the fastening straps 18. When mounted, the fastening belt 16 is placed on the outer rim 19 of the end support 6 and is fastened to the outer face 19 of the end support 6 along with the two anchor pins 13. The detachable half zipper 20 sewn onto the fastening belt 16 can be attached to the other zipper half 21 sewn to the edge of the bed cover 7 (Fig. 3).

An enlarged view of the bed cover 7 is shown in Fig. 3, the shell 26 of which is made of a polyester-woven fabric stitched between two layers of impregnated textile material. The bed cover 7 is provided with circular webs of textile anchoring tracks 22 in the arrangement shown in FIG. In the passages formed by anchoring tracks 22 sewn along its edges, 12 mm diameter aluminum rod frame members 23 are bent according to the barrel arch of the bed cover3.

HU 215 678 Β is pushed in. The layered material of the bed cover 7 has an indentation of two articles 24 shown in Figure 3. By sewing the edges of the cuts, the spherical article surface 46 shown in Figure 6 is needed to seal the headboard end of the bed cover 7. The stiffening of the spherical surface 46 as shown in Figure 6 is also solved by the frame members 23 which are inserted into the retaining tracks 22 and are bent in accordance with the arch. The bedspread thus made can be folded along the longitudinal axis of the bed to form transverse accordion ridges,

The body of the inner ribbed heat-shrinkable plastic wall housing of the end support 6 (Fig. 2) has a symmetrically formed rectangular cross-sectional passageway 27 for the cooling block 28 or alternatively a venting block 29 for use therewith. The cover of the cooling block 28 or the ventilation block 29 may be made of thermosetting plastic. Block-like heaters 30 are incorporated in the two half-boxes of the end support 6 (Fig. 2). The electric heaters 30 of the rear support 6 are connected to the fans 31 by air passages 32 inside the box. With the two heating units 30, the desired temperature in the bed space can be controlled by the thermostats 33. By placing the cooling block 28 in the cavity 27 of the headrest 6, a southern air conditioner is provided. Operation of the cooling block 28 is possible in either of the two flow paths, via the cooling thermostat 34 and the hygrostat circuit 35, respectively, depending on whether the bed space needs to be cooled or dried, and the appropriate controller closes the circuit.

In such a structural arrangement, the headrest 6 automatically solves the heating, cooling and air drying task in the confined bed space. The conditioner built into the end support 6 can be changed to a northern type by placing the vent block 29 in its cavity 27. A radial fan 43 is integrated in the vent block 29, which opens the vent damper towards the open space, creating an overpressure in the duct. Occasionally enriched humidity in the bed area is detected by the hygrostat 46 and, when the air humidity rises above a set value, for example 75%, turns on the ventilation fan 43, when the exhaust air exhausted from the bed space is replaced by the sides 9 and 7 ). Assuming that the northern type of air-conditioning bed is used in a room with a temperature below 25 ° C, the bed space is also ventilated. The cooling of the bed space is required when it is overheated, which can be done on the control panel 10 by the pressure switch 55 operating the ventilation fan 43 (Fig. 4).

The ventilation equipment built into the rear end 6 is automatically operated as long as the desired bed base temperature is approx. 32 ° C, humidity approx. Set to 75% on regulators 33, 34, 35, 46. It is expedient to make the heating units 30 of the rear support 6 in two stages, since different performance requirements arise during use. For example, the heating unit 30 may have a power rating of 400-500 W, the second power level should be chosen twice, in this case 800-1000 W. The control panel 10 is shown in Fig. 4, which includes the heating, cooling, or ventilation 49 and the time switches 51. The flush switches 49 are the 1st and 2nd degree switches of the heating units 30 of the end support 6.

The timer 51 operates the heater for 1 to 5 minutes, the timer of which can be set by the rotary lever 52, repeated as desired until the desired bed temperature is reached. The main switch 50 on the switch panel 10 can be used to commission the end support 6. The pressure switch 53 can be used to illuminate a bulb 48 mounted on the bedside wall of the end support 6. The sensor 25 of the temperature display 54 of the control panel 10 is located on the wall of the end support 6.

The air conditioner is powered by 220 V, 50 Hz mains. A commercially available Peltier battery can be operated at a voltage of 6 or 12 volts, so in the cooling block 28 (FIG. 2), a 220/12 V voltage-reducing power supply 47 is connected to the Peltier cooling unit 36 in front of the Peltier cooling unit 36. The use of the Peltier refrigerator 36 allows for the construction of an air conditioner with an air conditioner located below the bottom 2 of the air bed. In this embodiment, the air handling unit 58 is integrated into a box below the bed base 2 (Fig. 6) and operates or uses the same embodiment as the rear seat 6 (Fig. 2). The difference results from the design of the bed due to the placement of the AHU 58 (Fig. 6) below the bottom 2.

At the rear end 6 of the under-bed air-conditioned berth, the air conditioning unit 58 is connected to the bed space C by an air duct 32 having a supply port 40 extending into the bed space. In this embodiment, the bed cover 7 is secured by a flange 60 which can be inserted into the coffee 59 of the end support 6 (Fig. 6). The position of the air-conditioning bed before use is shown in Figure 7. Here, while sitting on the bed, the bed cover 7 is pulled toward you to occupy the position C in the bed space shown in Figure 8.

Some of the advantages of the bed structure of the present invention over the prior art can be summarized as follows:

- provide the optimum air condition for resting, regardless of climatic conditions,

- the bed unit can be set up according to the place of use, adapted to cold, tropical or hot climates,

- can be used as a lying room in a dwelling, for therapeutic purposes, for the production of sterile bed air or for detoxification of the human body.
