Definitions

  • the present invention relates to the field of an evaporative air cooler. More particularly, present invention relates to the control systems of various functions of evaporative air coolers.
  • An evaporative cooler (also swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water.
  • the temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than refrigeration.
  • evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants.
  • coolers are used for residential installation or for industrial installation.
  • the principles of evaporative air-cooling have been exploited for several decades by people of many countries to obtain relief from uncomfortably warm environments. Air coolers are more effective in dry, hot tropical locations.
  • Present day air coolers typically comprise of a body, a water tank, fibre pads (of different possible materials), air moving device (axial or centrifugal or cross flow fans) and water circulation system.
  • a motorized air moving device mounted within the body of the air cooler - with fibre pads on at least one of the sides of the air cooler - blows the cool air from the air outlet (usually at front or top of the air cooler).
  • the loosely woven fibres of the fibre pads are made of hay or cellulose. In case when fibre pads are made of hay, hay wool is filled in the cotton net of the fibre pad l and in the case when fibre pads are made of cellulose, the fibre pad consist of paper and special adhesive with multiple layer of corrugated paper arranged in honeycomb manner. The fibres of the pads are kept wetted using a water distribution system.
  • Cooling of air using evaporative air coolers is controlled in various ways through various functions installed in said coolers.
  • Normal controlling functions include air speed control (high, medium, low etc), air delivery mode (for example natural, normal, sleep etc), off or on timer, cooling, left/ right swing etc.
  • evaporative coolers with ionizer All these different functions are controlled by electro-mechanical switches or by electronic control panel and remote control. In all such cases, a user has to touch and operate the switches or buttons. However, this leads to mechanical wear and tear, noise and also hygiene issues.
  • the embodiment of the present invention provides a gesture control system for an evaporative air cooler, mainly comprising:
  • said evaporative cooler components are the components of existing evaporative coolers for which present controlling system has been developed.
  • Said components mainly include Mains Supply, Power supply or power board, main motor, pump and swing motor. These components mainly are controlled through present gesture control system for an evaporative air coolers.
  • Said Controller 1 is provided for processing the gesture input while recognising and processing the input so as to impart the gesture's impact in controlling the cooler functions via Recognised gesture output means.
  • Said controller 1 further comprises of:
  • Emitting means which tram its infrared light. There are 2 emitting means that emits IR light one after another. Once IR light is obstructed by any object the strength of the reflected light signal increase one after another, the means reflect more lights to proximity sensor.
  • ⁇ Sensing Chip which is a proximity sensor, which senses the movement of object and compare the light object coming from two different emitters. This data is then multiplexed and then sent for processing through data processing means.
  • Data Processing means wherein the data received from sensing chip is acquired in separate data streams as one per emitter. Said multiplexed data is processed to obtain the measurements of signals that are in turn obtained from reflected IR that occur slightly one after another.
  • Data Buffer means The data processed from said data processing means is received here and is buffered to maintain the strength of its signals obtained to deliver the exact output signal strength for segmentation process.
  • Segmentation means which selects an adequate threshold level for gesture done using an object.
  • Said analysed signals are then compared with the pre-set gestures stored in the memory means. Based on which, the present system analysis what kind of gesture is made and to control what.
  • Gesture recognition means is provided for recognition of processed gesture to be further sent to the controller 2 for further processing.
  • Said Controller 2 is provided for receiving and processing the recognised gesture to impart the gesture's impact in controlling the cooler functions by further sending signals to the power board in the cooler for controlling various functions of the cooler via Recognised gesture output means.
  • Power board is the power supply unit is the piece of hardware that's used to converts mains Alternate current to low-voltage regulated Direct Current power for the internal components of PCB.
  • WORKING OF THE INVENTION Referring to fig. 1 to 5 illustrates the working of present system for controlling various functions of the cooler. Said processes of controlling involves following steps:
  • the work flow of the system starts with Gesture input.
  • the light from two emitters get reflected to the proximity sensor.
  • the sensor provides distance measurement using reflected IR light.
  • Received data is further sent for Data processing and segmentation process for analysis and detection of the kind of Gesture made.
  • After recognition of the signal it sends the commands to the controller 2 to process and provide electrical signals to the power board to perform the task as conveyed through the gesture input.
  • Swing Function Swing ON Swing OFF.
  • Timer Function Timer ON Hold For 4 seconds 2 for 1, 2,..upto 7 Hours and Hour timer activated OFF and so on up to 7 hours and then OFF
  • the system is less corrosion sensitive mainly due to the use of capacitive sensing buttons.
