Description

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

There are known air conditioning devices with conditioning systems and air outlet systems. Such air conditioning devices are used in particular for hotel rooms, wherein the exhaust air is usually sucked off again via the adjacent wet cells. The disadvantage of many known air conditioning devices is the high noise level of the technical equipment and the inevitable due to the volume flow and Ausblasortes drafts, which often trigger comfort complaints at the guests. Other known air conditioning devices that avoid drafts are thermally inert and respond slowly to load fluctuations or individual change requests.

From US 3 928 876 A a bed is known having a horizontal part extending below a person lying on the bed and being circulated upwards to the person through the air, the bed also having a structure at the end thereof protrudes upward beyond the horizontal part and from its elevated part air in a substantially horizontal direction towards the person, preferably by an adjustable lamellar arrangement, is discharged.

From DE 86 00 553 U1 a padded bed is known, which is provided at the top and bottom part with a standard cheek. At the stand cheek bores are available to which a bed box can be mounted with it arranged Lattenrostrahmen and rotating sheets at different heights.

It is therefore an object of the present invention to eliminate the above-mentioned disadvantages of known air-conditioning devices. The noise should be reduced to a minimum, with a maximum sound pressure level of 20dB (A) in the room. Drafts of any kind should be avoided for the hotel guest, and the hygienic conditions for the guest should be improved. At the same time, the installation should be very easy.

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 in the hotel room on the necessary and thus existing bed box. The supply air is alternately heated or cooled via lateral outlet openings in the side walls of the bed box, according to the room loads, and thus introduced into the room draft-free, or injected via an integrated switching mechanism directly over the mattress of the bed. With side walls of the bed box are not only the longitudinal walls of the bed box, but also the walls at the foot and / or head to understand. The advantage of the air supply over the bed is mainly in the uniformity of the air flow, so that with low drafts and low noise high air intake is possible.

The air supply into the room through the mattress through the room air conditioning the possibility of heating or cooling of the mattress. In addition, the mattress can be dried so as to reduce or eliminate mite formation. If the supply air is provided with a disinfectant, even the formation of bacteria in the mattress can be eliminated, so that the room conditions are even suitable for high-grade allergic persons.

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 1 source air ducts or side channels 6 are provided with lateral Quellauslässen or lateral outlet openings 5 , through which supply air draft-free in the room can be introduced (source air mode ) on the side walls 3 of the bed box. It is advantageous to use special outlets, which have a low pulse.

In addition, a mattress air chamber 10 is provided with further upper outlet openings 8 below the mattress 2 and the slatted frame 9 , so that the supply air can be injected directly over the mattress 2 of the bed (mattress air operation). By special edge strips or Anpressprofile 17 and the arrangement of the individual nozzles in a chamber plate ensures that no air loss can take place on the lateral edges of the mattress. The mattress air chamber 10 is replaced by a chamber plate with adjustable individual nozzles or distribution rails for separation from the side air flow. As will be described in more detail later, via an integrated switching unit 16, the supply air can either be blown only laterally out of the bed box 1 or only via the mattress 2 or both at the same time.

The functions "room flow source air operation", "mattress flow cooling or heat operation", "drying operation mattress" and "disinfection operation mattress" are preferably provided.

In the source air mode, the supply air is blown out via the lateral outlet openings 5 . Due to the large lateral surface of the bed box 1 with a relatively high number of outlet openings 5 , a very uniform space flow is achieved. In addition, low noise is achieved by a low ejection speed with the fastest possible heating or cooling of the room.

When Matatzendurchströmung the cooled or heated air is blown over the mattress 2 . This can be pleasant for the guest to cool the bed in the summer during the sleep times or to heat something in the winter. There is also the possibility of preheating or pre-cooling of the bed for the highest comfort demands.

The source air operation and the mattress flow can also take place simultaneously. This causes turbulence and low-emission supply of cooled or slightly heated air to the person on the bed. Pollutant absorption 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, which is even suitable for allergy sufferers, is achieved.

In the drying operation for the mattress 2 is also a mattress flow. In this case, the air can be treated or flow parameters are used to dry the mattress after the sleep time, preferably in the absence of the guest. The risk of an accumulation of mites in the bed is reduced, which is a significant problem in hotels.

In the disinfection mode for the mattress is also a mattress flow. In this case, the air may be provided with a disinfectant to disinfect the mattress 2 after the sleep time, preferably in the absence of the guest. As a result, the formation of bacteria in the mattress 2 and other hygienic requirements is taken into account. Of course you can the disinfection operation can also be carried out simultaneously with the drying operation. For the disinfection operation, a disinfection device can be accommodated in the bed box, which offers the operating personnel the option of making the mattress 2 of the respective bed as free of germs as possible or of obtaining it.

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 over a total of three outer sides of the bed box below the bed box recess.

The introduction of air into a distribution chamber 14 takes place 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. With connecting parts, a displacement of the beds can be realized by a certain amount. The distribution chamber 14 is connected to the side of the bed box 1 via a side channel supply port 7 with the side channels and a mattress chamber supply port 11 to the mattress air chamber 10 .

Switching in the distribution box via one or more preferably together acting slide valves 15 for all connections. The various possibilities of introducing the supply air into the room can take place alternately. Thus, via an integrated switching unit 16, the supply air either only laterally blown out of the bed box 1 or only on the mattress or both at the same time. Accordingly, it is also possible to switch between the states "room flow source air operation", "mattress flow cooling / heat operation", "disinfection operation mattress" and "drying operation mattress". The control of the switching unit can be done automatically or individually at the request of the guest to increase sleep comfort. The automatic control can be done via a detection system which detects whether a guest is present in the hotel room (presence switch) or not (absence switch). Such a detection system, which may be located in the area of the door, may register, for example, whether the guest enters the room or leaves the room. But it is also possible that the switch is made via the hotel reception.

The supply of the individual guest room is usually done with treated primary air, which meets the air conditioning requirements, via a conventional central system. An air handling unit may be connected via a port to a home-centralized conditioned air supply system.

It is possible to deliver the air supply system or bed outlet system prefabricated. The system according to the invention is therefore particularly suitable for renovation purposes.
