Bed with air duct unit for air conditioning of rooms

The present invention relates to air conditioning devices for rooms, in particular for hotel rooms or hospital rooms.

Air conditioning systems with air conditioning systems and air outlet systems are well known. Such air conditioning systems are used in particular for hotel rooms, with the exhaust air usually being extracted again via the adjacent wet rooms. The disadvantage of many known air conditioning systems is the high level of noise generated by the technical systems and the unavoidable draughts caused by the volume flow and the location of the blow-out, which often trigger complaints about comfort from guests. Other known air conditioning systems that prevent draughts are thermally sluggish and react slowly to load fluctuations or individual requests for changes.

It is therefore an object of the present invention to eliminate the above-mentioned disadvantages of known air conditioning devices. The noise development should be reduced to a minimum, with a maximum sound pressure level of 2OdB(A) being achieved in the room. Draughts of any kind should be avoided for the hotel guest and the hygienic conditions for the guest should be improved. At the same time, installation should be very simple.

This object is achieved by a bed according to claim 1. The dependent claims relate to advantageous embodiments of the invention.

A central element of the invention is the introduction of air into the hotel room via the necessary and therefore existing bed box. The supply air is alternately heated or cooled via side outlet openings in the side walls of the bed box, depending on the room load, and thus introduced into the room without drafts, or blown directly over the mattress of the bed via an integrated switching mechanism. The side walls of the bed box are not only the long walls of the bed box, but also the walls at the foot end and/or the head end. The advantage of supplying air via the bed lies primarily in the uniformity of the air flow, so that a high air supply is possible with minimal drafts and low noise.

The supply of air into the room through the mattress opens up the possibility of heating or cooling the mattress via room air conditioning. The mattress can also be dried in this way in order to reduce or eliminate the formation of mites. If the supply air is provided with a disinfectant, the formation of bacteria in the mattress can even be eliminated, so that the room conditions are suitable even for people with severe allergies.

The present invention is explained in more detail below using preferred embodiments with reference to the accompanying drawings.

Fig. 2 shows a longitudinal section through a bed with air guide unit according to the present invention.

Fig. 1 shows a cross section through a bed with bed box 1 and air guide unit 4 according to the present invention. In the bed box 1, on the side walls 3 of the bed box 1, source air ducts or side ducts 6 are provided with lateral source outlets or lateral outlet openings 5 through which fresh air can be introduced into the room without drafts (source air operation). It is advantageous to use special outlets that have a low impulse.

In addition, a mattress air chamber 10 with additional upper outlet openings 8 is provided below the mattress 2 and the slatted frame 9, so that the supply air can be blown in directly over the mattress 2 of the bed (mattress air operation). Special edge strips or pressure profiles 17 and the arrangement of the individual nozzles in a chamber plate ensure that no air can be lost over the side edges of the mattress. The mattress air chamber 10 is provided with a chamber plate with adjustable individual nozzles or distribution rails to separate it from the side air flow. As will be described in more detail later, the supply air can be blown out either only from the side of the bed box 1 or only over the mattress 2 or both at the same time via an integrated switching unit 16.

Preferably, the functions "room flow - source air mode", "mattress flow - cooling or heating mode", "mattress drying mode" and "mattress disinfection mode" are provided.

In the source air mode, the supply air is blown out through the side outlet openings 5. The large side surface of the bed box 1 with a relatively high number of outlet openings 5 results in a very even room flow. In addition, a low blow-out speed ensures a low

Noise level is reached when the room is heated or cooled as quickly as possible.

When the mattress is blown through, the cooled or heated air is blown out over mattress 2. This can be pleasant for the guest, as it allows the bed to be cooled in summer or heated a little in winter while they are sleeping. There is also the option of pre-heating or pre-cooling the bed for the highest level of comfort.

The source air operation and the mattress flow can also take place at the same time. This creates turbulence for the person lying on the bed and a supply of cooled or slightly warmed air with low pollutants. The absorption of pollutants via air turbulence is thus minimized. The result is very good air quality in the lying area. In conjunction with the mattress flow, the highest air quality is achieved, which is even suitable for allergy sufferers.

During the drying operation for mattress 2, the mattress is also air-flown. The air can be treated or air-flow parameters can be used to dry the mattress after sleeping, preferably in the absence of the guest. This reduces the risk of mites accumulating in the bed, which is a significant problem in hotels.

During the disinfection process for the mattress, the mattress is also air-flowed. The air can be provided with a disinfectant in order to disinfect the mattress 2 after sleeping, preferably in the absence of the guest. This takes into account the formation of bacteria in the mattress 2 and other hygienic requirements. Of course, the disinfection process can also be carried out at the same time as the drying process.

For disinfection purposes, a disinfection device can be installed in the bed box, which offers the operating personnel the possibility of making or keeping the mattress 2 of the respective bed as germ-free as possible.

As can be seen in Fig. 2, lateral outlet openings 5 can also be provided at the foot end of the bed, so that heated or cooled supply air can be introduced into the room via a total of three outer sides of the bed box below the bed box recess.

The air is introduced into a distribution chamber 14 either from the headboard of the bed via a distribution channel installed in the furniture or in the partition wall or via special air outlet boxes integrated in the floor structure. The beds can also be moved by a certain amount using connecting parts. The distribution chamber 14 is connected to the side channels at the head end of the bed box 1 via a side channel feed connection 7 and to the mattress air chamber 10 via a mattress chamber feed connection 11.

The switchover in the distribution box is carried out via one or more slide valves 15 for all connections, preferably working together. The various options for introducing the supply air into the room can be used alternately. For example, an integrated switchover unit 16 can be used to blow the supply air either from the side of the bed box 1 or only over the mattress, or both at the same time. Accordingly, it is also possible to switch between the states "room flow source air mode", "mattress flow cooling / heating mode", "mattress disinfection mode" and "mattress drying mode". The switchover unit can be controlled automatically or individually at the guest's request to increase the sleeping comfort.

comfort. The automatic control can be carried out via a detection system that recognizes whether a guest is present in the hotel room (presence switch) or not (absence switch). Such a detection system, which can be installed near the door, can, for example, register whether the guest enters or leaves the room. However, it is also possible for the switch to be made via the hotel reception.
