Background technology
Air processor is a kind of novel household electrical equipment, and it has functions such as automatic detection smog, elimination dust, elimination peculiar smell and pernicious gas, sterilization, humidification, dehumidifying.With the air purifier is example, and air purifier is made up of systems such as circuit for producing high voltage, anion generator, ventilation blower (gentle breeze fan), air cleaners usually.By the ventilation blower in the air purifier room air is circulated, the air that pollutes is removed all contaminations or absorption after filtering by the air cleaner in the machine, process is contained in the anion generator (circuit for producing high voltage during work in the anion generator produces negative direct current high voltage) of air outlet then, with the continuous ionization of air, produce a large amount of anions, sent by ventilation blower (gentle breeze fan), form the anion air-flow, the purpose that reach cleaning, purifies air.Wherein, filter, anion generator, ventilation blower that is used to carry out air cleaning etc. is referred to as clean unit.
The purification style of air purifier mainly contains following type: the one, filter absorbent-type, promptly adopt physics formula purification style, utilize the porous filter material, as nonwoven, filter paper, fiber, active carbon, foam etc. (the strongest filter material of adsorption capacity is a HEPA high-density air filter material at present), suspended particulate in the absorbed air, pernicious gas, thus purify air; The 2nd, the electrostatic precipitation type, promptly electrostatic purification style makes in the air pollutant charged by corona discharge, uses dust collect plant to collect charged particle, reaches the purpose that purifies air; The 3rd, the chemical formula purification style, as: photocatalytic method or formaldehyde scavenger or medicament etc., it is exactly compound having again: utilize above-mentioned filtration, static and/or chemical cleaning method mode simultaneously, purify air.In principle, several modes that purify air all have certain detergent power to room air more than.
Progress along with science and technology, air purifier is as a kind of intelligent artifact, also experienced the different stages, phase I: the air processor that fixing, clean unit can not lift, this air purifier is by physics formula purification style (as: active carbon or HEPA screen pack), electrostatic purification style (as: anion) or chemical formula purification style (as: photocatalytic method or formaldehyde scavenger or medicament etc.), in the fixed position, level altitude purifies air.
Second stage: air purifier is fixing, the liftable air purifier of clean unit.This air purifier is installed in the fixed position, but the air cleaning member in the clarifier can move up and down according to circumstances at differing heights, thereby reaches the effect of a certain regional air of effective circulation.It is ZL03106666.6 that the concrete technical scheme of relevant this air processor is asked for an interview the patent No., and name is called the patent documentation of " air processor ".In this patent documentation, disclosed following content: clarifier is provided with lifting unit, this unit comprises the tooth bar that longitudinally is arranged on the casing inner surface, thereby vertically forms on the outer surface of housing so that hold the guide groove that tooth bar leads to the elevating movement of housing; With tooth bar engagement and the pinion that supports rotationally by housing; And be arranged on the housing place and make pinion clockwise or the motor that is rotated counterclockwise.During the motor rotation, make air cleaning member pass through tooth bar and move in vertical direction.
In addition, also has a kind of air purifier that moves certainly in the prior art.The driver part of this air purifier by being provided with is implemented in around the presumptive area and purifies air when mobile.It is ZL200410043117.4 that concrete technical scheme is asked for an interview the patent No., and name is called the patent documentation of " air purifying robot and system thereof "; ZL200510051309.4, name is called the patent documentation of " air processor and control method thereof ".This robot can realize moving up and down but its air cleaning member can't be implemented in differing heights from moving.
In above various air purifiers, the clean-up effect of the air purifier that fixing, clean unit can not lift is far from clean unit can lifting or the good purification of air purifier movably.But, each defectiveness of the air purifier of second stage, as first kind, owing to can not move, can only carry out air cleaning in the space with regard to differing heights in the original place, and, owing to do not detect the sensor of elevating mechanism relevant height position, when elevating mechanism carries out lifting, when the child touches the cavity that is equipped with elevating mechanism in the casing with hand, and there is potential human injury's danger.And second kind, though can move, can only carry out air cleaning in a height level's space in different places.

Fig. 1 is the structure chart of the air processor in the embodiment of the invention one, and Fig. 2 is the structure chart of air processor when lifting unit rises in embodiment illustrated in fig. 1.As shown in Figure 1 and Figure 2, described air processor comprises air processor 1 and mobile device 2, this air processor 1 is as the funtion part of air processor, be used to purify air or the humidification/dehumidifying of air, described mobile device 2 comprises housing 21, driving wheel 22 and driver part etc., realizes air processor moving certainly on ground by described mobile unit 2.In the housing 21 of mobile device 2, also be provided with control module (figure does not show), be connected with lifting unit 3 between described air processor 1 and the mobile device 2, on described mobile device, be provided with the accommodation space 23 that sets to the concave, be used to accommodate described air processor 1 and lifting unit 3.Described lifting unit 3 is controlled by control module and carries out free lifting, thereby changes the height that is connected air processor with it.Described air processor also comprises the detecting unit of being located on air processor and the mobile device, be used to detect the barrier that the zone between described air processor and mobile device may occur when lifting unit rises, in case detected barrier, detected obstacle signal is sent to described control module, can control mobile unit by control module and in time change the direction of advancing, in order to avoid produce disadvantageous consequence with the barrier collision.
As shown in Figure 3, Figure 4, structure chart for the air processor in the embodiment of the invention two, described air processor comprises two parts up and down, and top is divided into main body and is positioned at the air processor 1 ' of main body, and last main body plays the effect of supporting and holding various parts.The bottom is divided into mobile device 2 ', and it comprises housing 21 ', driving wheel 22 ' and driver part etc.And, in housing 21 ', also be provided with control module and power supply, as rechargeable battery etc., described going up between main body and the mobile device 2 ' connected by lifting unit 3 '.In addition, air processor also comprises the detecting unit of being located on air processor 1 ' and the mobile device 2 ', is used for detecting the barrier that the zone between the described air processor 1 ' and mobile device 2 ' may occur when lifting unit 3 '.
In the above embodiments of the present invention, described detecting unit can adopt multiple structure and principle, shown in Fig. 2,4, detecting unit is for being located at described mobile device 2,2 ' upper surface and described air processor 1, the sensing element 4 of 1 ' lower surface (not shown), each group sensing element 4 forms a signalling channel.Better, sensing element 4 can as wireless electron signal transmission element, infrared ray transmission/receiving element, light transmission/receiving element or Laser emission/receiving element, can certainly be above-mentioned combination arbitrarily for multiple.For the zone that makes detection wider, and information is more accurate, be provided with a plurality of sensing elements 4 in the corresponding position of mobile device and air processor, in addition, the alignment placement of paired sensing element 4 is the equal angles setting, better, certain angle that each radiated element involves, as 20 °, for making surveyed area is continuous, can adopt optical element that the signal that each radiated element sends is dispersed processing, so that the zone that signal covered that every group of two groups of transmitting element adjacent one another are send continuously.In like manner, before receiving element, also increase optical element,, like this,,, just can be detected, the situation of omission can not occur as long as there is barrier to enter this surveyed area just make surveyed area continuous to enlarge the zone of receiving element received signal.Described continuous detection zone is around a week or part around the described lifting unit.
Because when air processor is the lifting unit rise, Yi Bian handle air, as purifying or humidification, move on one side, in moving process, if barrier is arranged, normally the front end of air processor touches barrier earlier, therefore, can make the front end that surveyed area only is located at air processor, for example, as shown in Figure 2, paired sensing element 4 is that symmetry axis is symmetrically distributed with the diameter in the preceding semi-circumference of direction of advance, can detect the barrier that may run into to greatest extent with this when advancing.
In the air processor traveling process, when if signal receiving element receives the signal that the signal radiated element launched, signal receiving element is given control module with the signal feedback of induction, after control module is received signal, clear between air processor and the mobile device is described, it is constant that air processor will be kept former direct of travel, moves on; If a certain position of air processor in traveling process, a certain signal receiving element does not receive the signal that the signal radiated element is launched, the air processor control module interposition that can judge air processor and mobile device is equipped with barrier thus, the mode of dodging of the former direct of travels of change such as the mobile unit of air processor is taked to retreat under the driving of control module, turning moves, and receives the signal that the signal radiated element is launched once more until signal receiving element.Specifically, if the described signal receiving element that is in air processor front end left side does not detect the signal that corresponding signal radiated element is launched, then can judgement in the signal area of air processor left end, barrier be arranged, described control module control described mobile device turn right to; If the described signal receiving element that is in air processor front end right side does not detect the signal that corresponding signal radiated element is launched, then can judge in the signal area on air processor front end right side has barrier, described control module control described mobile device turn left to; If the described signal receiving element that is in the air processor front end does not detect the signal that corresponding signal radiated element is launched, then control module is judged has barrier in the signal area of air processor front end, described control module is controlled described mobile device and drawn back.Here, the angle that turns to of the described mobile device of aforementioned control can preestablish or be set at random by described control module.
