Definitions

  • the present invention relates to furniture with a natural air purifier where the filtration is done by plants and where thanks to a control unit an air flow is forced in the roots of the plant.
  • the air purifier includes sensors so that helps not only the performance but provides important data regarding the pollutants and conditions of the environment.
  • Furniture comprises bi- or three-dimensional mobile or fixed or built-in furniture, like tables, chairs, beds, desks, dressers, wardrobes or cupboards of different kinds. These objects are usually kept in a house or other building to make it suitable or comfortable for living or working in. There is a need to have a healthy atmosphere in living and working spaces, thus the market developed various types of air purifying devices to render the air clean and free of toxic substances.
  • air purifiers are devices that filter air contaminants, toxic agents, materials, dust, VOCs (volatile organic compounds) through various filters in order to provide clean air.
  • a natural air purifier powered by plants is, among other air purifiers, a device that uses the roots of the plants as filters.
  • Object of the invention is to propose an improved natural air purifier for purifying air in indoor spaces which is able to purify air in an optimized manner, in particular with an optimized air flow to the roots and through the matrix in which the roots are enrooted taking into consideration environmental conditions and which resolves the above mentioned space problems.
  • an air purifier comprising:
  • the second flower pot is provided with one or more holes; and (a2) the first flower pot is provided with an opening;
  • control unit housed in said opening and comprising:
  • (b5) a microcontroller suitable to receive data from the sensors and to send signals to the fan;
  • the ventilation element may, for example, be situated in a wall of the furniture or of its recess, if present.
  • the ventilation element can be, for example, a perforated wall, a grid, a fan or similar.
  • Air quality sensors may be selected among a CO sensor, a C0 2 sensor, a VOC (volatile organic compounds) sensor, a NO x sensor, an SO x sensor, a particulate matter (PM) sensor for different particle sizes, for example PM 2.5 (particulate matter with a diameter lower than 2.5 ⁇ ), a pollen sensor, etc.
  • the insertion of the perforated second flower pot in the first flower pot creates a space between the walls of the pots and permits a defined air flow in between which is channeled through the holes in the second flower pot and through the control unit with the fan.
  • a very functional air chamber is formed internally which permits the air to circulate very well inside, to pass more times in the soil and thus to purify even more; what would not have been possible if the internal pot was flush with the external one, there would be only one passage, here on the other hand the passages are multiple and there is an extended flow all around.
  • the particular combination of sensors permits to control parameters which are important for the air quality, the user of the air purifier gets important data which can be corrected/influenced by the system as will be explained in the following.
  • the built-in air purifier housed in a furniture provides a furniture which not only renders rooms comfortable for living or working in providing storing, sitting, eating or working elements but at the same time gives the furniture a functionality to purify the indoor air quality without occupying additional space to the space already occupied by the furniture.
  • the opening or recess in shape and dimension corresponds to the second flower pot of the air purifier such that the second flower pots fits into the opening or recess permitting air flow out of the furniture.
  • the furniture if it is a closed furniture, may contain holes and/or a grid for the air passage.
  • fixing means to fix the air purifier inside the opening or recess.
  • Such fixing means can comprise screws and relative holes in the air purifier as well as in the furniture.
  • the external flower pot could, to be suspended in the opening, have an upper edge wider than the dimensions of the opening.
  • the expert simply individuates other fixing means with his general knowledge.
  • a preferred shape for the recess and the external flower pot is a cuboid, like a cube.
  • the control unit further comprises a Wi-Fi module.
  • a Wi-Fi module permits a remote control and monitoring of the system and a communication with external devices, like thermostats of heating units, an air-conditioning unit, air humidifiers, other filters etc. to react on ambient parameters on the bases of the data collected by the sensors. Data handling and storage from a smartphone, a tablet or a PC is easily possible. On the contrary, a Bluetooth connection, for example, would only permit direct connections.
  • the air purifier further contains a self- watering unit.
  • a self-watering unit helps to increase the humidity level in the matrix where the roots are engrained and avoids that the plant dies because of water shortage.
  • Experimental results show that an elevated humidity, in particular when the matrix is soil, results in an increased air passage and in an increased absorption of toxic substances and thus an increased air purification.
  • the self-watering unit comprises
  • valve system activatable by the microcontroller, which closes or opens the water flow from the tank to the flower pot.
  • the water flow from the tank to the second flower pot advantageously takes place by capillary action, thus the soil or matrix sucks water only in case of necessity, but in another embodiment, the suction of water can be sustained by a pump.
  • the microcontroller preferably contains an algorithm which in case of low air quality signals from the air quality sensor controls the self- watering unit of the air purifier such that the humidity in the soil present in the second flower pot is raised.
  • Another possibility to improve the air quality is to increase the air flow through roots and matrix/soil. Exploiting this effect, in case of low air quality signals received from the air quality sensor, the microcontroller, in a preferred embodiment, switches on the fan or raises the fan velocity. On the contrary, to save energy and to preserve the fan, in case of good air quality signals received from the air quality sensor, the microcontroller preferably reduces the fan velocity.
  • the microcontroller contains algorithms which calculate from the data collected by the sensors the necessary measures to improve air quality, in particular calculate the temperature, humidity or fan velocity which contribute to improve air quality, and in that the microcontroller pilots, preferably via a Wi-Fi module, at least one of the following elements: a heating unit of the living/working space, an air-conditioning unit of the living/working space, a humidifier unit of the living/working space, a self-watering unit of the air purifier if present and/or the fan velocity of the fan such that the desired temperature, humidity, fan velocity and/or air quality are obtained.
  • the microcontroller contains algorithms which permit the mapping of the collected data in function of time and place.
  • the air purifier provides environmental and soil data and permits the correction of them acting on external devices, like an air-conditioning unit, or internal devices, like the self-watering unit or the fan.
  • Temperature, humidity and fan velocity are factors which are correlated among each other that are influenced the one by the other.
  • the collected data preferably, are saved on dedicated servers and can be processed to create a map of the internal spaces based on the air quality and to calculate the different levels of air quality in different zones of the space and to interpolate the data to further improve the air quality.
  • This mapping can be of a more global type and cover the development over time and the local development of the air quality where the furniture with air purifier according to the invention is used.
  • the microcontroller indicates, in case of humidity values received from the humidity sensor which drop below a certain threshold value, water shortage in the water tank.
  • the user is notified of water shortage and can fill the tank with water.
  • the humidity sensor to obtain this information avoids an additional water level indicator which obviously can be another option for the air purifier according to the invention.
  • the air purifier further contains a first gasket which hermetically closes the space between the upper edges of the two flower pots and optionally a second gasket interposed between the opening in the first flowerpot and the control unit inserted therein, thus realizing a closed space to enforce the air flow only in the desired spaces and directions avoiding losses of air flow.
  • the air purifier further comprises a tube which extends from the water tank to the outside of said air purifier for adding water to the water tank and optionally a lid to close said tube. This avoids the extraction of the inner flower pot to fill the tank.
  • the tank can, advantageously, be created by a dividing plate positioned at a certain height inside the second flower pot.
  • This plate can contain the feeding tube and/or holes to let pass the tubes or strings to suck water.
  • Another embodiment of the invention provides an air purifier that further comprises a Reed contact and a magnet for switching on and off one or more of the components listed under points (b), and from (bl) to (b5) of claim 1 and/or a Wi-Fi module if present.
  • a Reed contact is a simple device to act on single parts of the system and to handle them independently one from the other. For comfort reasons, the Reed contact is, for example, situated in that lid.
  • said Reed contact is suitable to selectively activate single components of the control unit by pressing a switch being part of the Reed system for different durations of time.
  • the components may be those listed under (bl) to (b5) of claim 1, a Wi-Fi module, a pomp for the water tank, a valve of a self-watering unit, if present and similar. The user is enabled to manually control the system.
  • the Reed contact advantageously, activates the system or switches it off; it can let it work with or without Wi-Fi and can give visual information, for example regarding the air amount processed or in case of degraded air quality.
  • the visual information can, for example, be a blinking of the Reed system.
  • control unit of the air purifier is detachable from the first flower pot. This can be realized by attaching the control unit, for example, by screws to the first flower pot or by realizing threads on the control unit and on the opening and to screw the control unit with the opening. Another alternative may be, for example, a snap fit closure.
  • fan and sensors are incorporated in the control unit in a single block permitting to extract all together to substitute or repair comfortably single elements, like the sensors or the fan motor. This avoids, in case of damage or defect, to substitute the whole air purifier.
  • the fan is preferably a motorized fan.
  • soil is particularly preferred as it has better results in absorbing toxic compounds, especially compared to hydroponic culture.
  • the material for the flower pot preferably is ceramic, stone, metal or similar and not synthetic or plastic materials. Particularly preferred is a flower pot made of metal sheet. Synthetic or plastic materials are known to release toxic agents like plasticizers or other additives.
  • the second flower pot contains soil and at least one plant.
  • Plants which are particularly suitable to attract toxic substances and particulate matter are mosses of the Racomitrium type.
  • the air purifier flowerpot includes, a design shape flowerpot with a circular hole on its front and a inner flowerpot with holes that has to be inserted into the main flower pot.
  • the control unit has several sensors that detect the air quality and it is covered by metallic grid; this unit has to be inserted in the circular hole of the flowerpot.
  • the control unit may include: a fan, microcontroller, a Wi-Fi module, an indoor quality sensor, temperature and humidity sensors, carbon monoxide and carbon dioxide sensors and a PM 2.5 sensor.
  • the fan In operation, the fan aspires the air from the outside making it go through the roots of the plant and throwing it out of the control unit.
  • the aspired air from the top side of the flower pot goes through the roots and it is processed by the microorganisms that live and get generated in the roots of the plant.
  • This filtered air then passes through the holes of the inner flowerpot and exits the system by the control unit.
  • the fan may also aspire air from the control unit, make it go through the roots of the plant and release the air from the top side of the system.
  • the aspired air from the control unit passes through the holes of the inner flower pot and gets into the roots of the plant where it is processed by the microorganisms that live and are generated in the roots of the plant. This filtered air then exits from the top of the plant.
  • the filtration is also operated by the soil itself.
  • the systems In operation, once the control unit is connected to electricity, the systems starts working and preferably all the sensors are activated. In operation, as the sensors are activated, the system recognizes three main values: indoor air quality, temperature and humidity.
  • the system advantageously, is aware of how much air has gone through the system and has to be processed by the plant. This is fundamental to give the right levels of pollutants that the plant and the whole system have the ability to process.
  • control unit connects, for example, to a normal smartphone via Wi-Fi. Thanks to a smartphone it is possible to manage all the functionalities of the system.
  • the proprietary mobile software application (mobile app), in which all the values of the system are displayed. These values may include: indoor air quality, humidity and temperature. Moreover, the switching on and off of the fan can be managed.
  • the method may also include further sensors to determine pollution levels, plant diagnostics that will help in the determination of the levels of air that have to go through the system and that enhance the purifying properties of the plants.
  • Embodiments of the present invention not only use the natural properties of the plants and the soil to filter toxic agents from the air, but with the control unit and its sensors, the system can actively understand the pollution and humidity/temperature levels in order to calibrate precisely the amount of air and pollutants that have to be processed by the plant and the system.
  • Another aspect of the invention concerns the fact, that the air purifier can be independent from a furniture, thus can be a device that is not integrated into a furniture but intended as a an autonomous air purifier.
