Description
Technical Field

Background
The household air purifier mainly comprises a motor, a wind wheel, an air inlet, an air outlet, a filter screen, a control circuit and the like, and is used for removing suspended particles in the air, sterilizing, decomposing harmful volatile chemical substances VOC and the like, purifying indoor air or filtering allergic substances such as pollen and the like, and the household air purifier needs to be manually operated when being used, and is provided with a power supply, a function setting function, a gear adjusting function and the like. In recent years, some products use remote controllers, and remote control operations are performed in a short distance indoors. The purifier body is provided with a remote control signal receiver and a corresponding control circuit, so that the wireless infrared remote control mode with most of remote control functions common to household appliances is realized, namely, the remote control is operated to send out infrared signals, and the receiver recognizes, decodes and drives corresponding elements to execute required electric actions through a control chip and software according to signal instructions.
In view of cost reduction, volume reduction and the like, common remote controllers in the market mostly use infrared luminotrons with the wavelength of about 940nm, the working frequency is 38kHz, and the used components such as chips are civilian product grades with general technical performance. Because the remote control distance is not too high, the emission power of the remote control emitter is smaller, the common dry battery or button battery is used for supplying power, and the remote control receiving device is often integrated with other keys, indicator lights and the like which are manually operated on the same operation panel, and is arranged on the vertical elevation of the air outlet direction of the air purifier, namely the direction facing to the user, for the convenience of operation and observation, and the height is approximately level with the hand lifting operation position under the sitting posture of an adult.
For convenience in use, the household air purifier often needs to be provided with a plurality of light-emitting elements on the PCB board, and the light-emitting elements are used for displaying corresponding working states and data marks through the operation panel, and the colors of the light-emitting elements are red, green, yellow, blue, white and the like.
Because the emission power of the common remote controller is smaller, when the installation position of the infrared remote control signal receiver is closer to the light emitting element, the phenomena of mutual interference, diffraction, interference of the light scattering of the light emitting element and the infrared signal of the remote controller often occur, so that the receiver receives difficultly or the received signal is distorted, the remote control operation distance is greatly shortened, or the remote controller is malfunctioned or the machine generates misoperation, a great deal of inconvenience is brought to a user, and the air purifier equipment is damaged even by potential safety hazards, poor electrical contact and the like when the air purifier is seriously brought.
In order to reduce the influence of the interference, some devices install the receiver at a position far away from the PCB of the air purifier, although the interference degree can be slightly reduced, as the main electric appliance circuits of the whole machine are relatively concentrated near the operation panel, the remote control receiver can make the circuit connection of the control and execution circuit more complicated after being far away, the operation is inconvenient, the potential safety hazard is increased, and the display state of the purifier is difficult to directly observe in use; the remote controller has the advantages of improving the anti-interference capability by increasing the transmitting power of the remote controller on one side or adopting more complex advanced coding and decoding technology, increasing the cost, affecting the health by increasing electromagnetic radiation, shortening the service life of a battery and the like.

As one of the preferable modes of the invention, the inner wall of the reflecting shade 8 is coated with a reflecting layer, and the reflecting layer is made of metal or other materials with better reflecting performance.
The invention also discloses an anti-interference method of the anti-interference infrared remote control air purifier, which is characterized by comprising the following steps:
(1) The signal sources interfering with each other are arranged on different planes;
(2) The luminous components and the remote controller receiver are arranged on different planes, and can be applied to other electrical equipment, such as air conditioners, set top boxes and the like, so as to solve the problem of interference of infrared remote control signals;
(3) Further, a reflecting cover can be arranged on the outer side of the luminous element;
(4) The anti-interference condition can be further solved at the source by coating the infrared absorption reflecting layer on the inner side of the reflecting shade.
The working principle of the invention is as follows: the air purifier is powered on, and the corresponding button on the operation panel is pressed to start the air purifying component to work, and various functions can be realized, such as running the purifying function in different gears, working in an automatic mode, starting other functions at the same time, and the like.
When the remote control function is used, a battery is firstly arranged in a remote controller; traditionally, the user is faced with the air outlet of the air cleaner, i.e. facing the installation location of the remote control receiver. After the corresponding operation key on the key panel of the remote controller is pressed within the working distance range of the remote controller, the remote controller chip encodes an operation signal, loads the operation signal onto the infrared electromagnetic wave emitted by the emission tube and emits the operation signal to the space in front in the form of radio waves, after the receiving end of the remote controller receives the infrared signal with the operation instruction information, the receiving end of the remote controller decodes the infrared signal through the receiving chip to obtain the specific content of the operation instruction information, the operation information content is transmitted to the processing chip in the PCB, the chip further outputs the operation instruction to the execution circuit in the PCB, and the actual effect is the same as that of the key operation on the operation panel, and the air purification assembly operates according to the content of the remote control instruction.
The reflecting lampshade on the position of the luminous element on the PCB is a black plastic hemispherical shell, the luminous point of the luminous element is positioned at the focus of the reflecting lampshade, when the luminous element is lightened to emit light waves, the reflecting lampshade focuses scattered light waves to a smaller range and irradiates the inclined upper part of the air purifier, at the moment, the scattering amount of the light waves to the periphery is greatly reduced, and meanwhile, the reflecting lampshade absorbs and isolates most of visible light from infrared rays emitted by the luminous element, so that the scattering amount of the light waves to the front end of the air purifier is further reduced.
Because the reflection lampshade reduces the scattering and infrared radiation of the indicator lamp to minimum values, the interference electromagnetic wave density of the infrared electromagnetic wave emitted by the remote controller on the path of reaching the remote control receiver and in the peripheral range of the remote control receiver is greatly reduced. Namely: electromagnetic waves which are possibly interfered and are sent by various luminous elements on the PCB are mostly isolated outside the space range between the transmitting end of the remote controller and the remote control receiver, when a remote control signal reaches the receiver, signal parameters such as strength, fidelity and the like of the remote control signal are maintained and are not interfered and distorted by scattered light of the indicator lamp, so that the remote control operation of the whole machine is more sensitive and reliable, and the operation distance is also ensured.
The interference degree between the electromagnetic waves mainly depends on the approaching degree of the wavelengths of the two electromagnetic waves, and the technical scheme of the invention mainly aims to isolate and reduce the infrared rays scattered by the light source on the PCB and the electromagnetic waves which are closer to the wave band, such as near infrared rays, far infrared rays and the like, and does not need special treatment on the electromagnetic waves which have larger difference between other wavelengths and remote control signals and have smaller influence, so that the reflecting lampshade can be made of low-cost black plastics only, has a simple structure and low cost, and has better absorption and isolation effects on the infrared rays.
In practical application, the anti-interference performance can be effectively improved by only adopting the remote control receiver and the operation panel to be positioned on two different mounting surfaces, and the problem of remote control signal interference can be thoroughly solved by adding the reflective lampshade. The related technical scheme can be applied to other electric equipment to solve the problem of infrared remote control signal interference.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
