Abstract

The air conditioner has a heat sources and an air pressurisation source which can be controlled quickly to allow a small air space to be brought to a desired temperature rapidly. In Fig 1 warm air from a blower c, d, exits via a nozzle a, which may be positioned for example at the foot of a bed, the air entering between the mattress and the cover. In another embodiment the warm air may enter at the foot of a bag which envelopes a seated person. <IMAGE>

Description

CONFINED ENVIRONMENT AIR CONDITIONER This invention relates to a Confined Environment Air Conditioner.

The heating of beds by various means has been a normal practice for hundreds of years.

Methods ranging from wenches, warming pans, hot stones, hot water bottles, and latterly, electric blankets have been employed.

With the advent of central heating our general environment has become more comfortable but many people prefer not to use bedroom radiators, while enjoying the entry into a warm bed.

The present invention provides a prompt flow of controlled temperature air to the envelope formed by the lower mattress and the duvet above.

Warm air pressure will cause the duvet to rise slightly and allow the air to spread over the mattress surface and expel through natural outlets at the bed head, thereby raising the temperature of the bed over most of its area.

Set out below is an example with reference to the accompanying drawing in which: Figure 1 - shows two views of the Air Conditioner.

Figure 2 - shows a view of the Air Conditioner in its permanent position attached to the bed.

Figure 3 - shows a view of the Air Conditioner adapted for chair-bound elderly people using a special envelope.

Figure 4 - shows a view of a hand-held controller for people of sick or feeble disposition.

Figure - shows a view of standard control console.

Referring to the drawing - Fig. 1 The Air Conditioner comprises: (a) Nozzle (b) Upper outer sleeve (c) Lower inner sleeve containing heating elements (d) Motor mounting within floor standing base complete with air intake and filter unit Fig. 2 - shows the Air Conditioner with the upper outer sleeve (b) adjusted to correct height.

Note that the nozzle (a) sits snuggly just at the upper edge of the top mattress.

The shape of the nozzle is such to allow the duvet to be supported away from the mattress in order for air flow to be maintained.

By switching the unit on using the portable control console to select the required temperature and air flow rate, (Fig.5), air is drawn in through the intake and filter unit. Once air flow has been established then the heat sources is allowed to operate and the air flow temperature is increased to its designed level.

Fig. 3 - shows an adaptation of above for use with chair envelope where an elderly person can rapidly and cheaply enjoy the available warmth.

Fig. 4 - shows a hand-held safety controller for use with above.

Claims

1. A Confined Environment Air Conditioner comprises a bed mounted controlled pressure and temperature air-flow unit with air from sources passing over heat source, into space over mattress.

2. A Confined Environment Air Conditioner as in Claim 1 wherein upper nozzle sleeve can be moved up or down to suit bed height.

3. A Confined Environment Air Conditioner as in Claim 1 or Claim 2 wherein lower sleeve is secured to the bed and allows upper sleeve to fit inside or outside its dimensions.

4. A Confined Environment Air Conditioner as in Claim 1 or Claim 2 or Claim 3 wherein a locking screw or screws can be fitted to lower or upper sleeve to secure height or nozzle.
