Description
Technical Field
The invention belongs to the field of household appliances, and particularly provides an air conditioner and a negative ion generating device thereof.
Background
Negative ions, also known as "active oxygen" or "air vitamins", are a substance essential to the health of human beings, like sunlight and air. Scientific research shows that the content of negative ions in the air is an important factor for determining the quality of the air, and the air contains a proper amount of negative ions, so that the air can efficiently remove dust, sterilize and purify the air, and can activate oxygen molecules in the air to form oxygen-carrying negative ions, thereby being beneficial to the respiratory system and metabolism of a human body.
With the increasing demand for quality of life, negative ion generators (such as the negative ion air cleaning device for air conditioners disclosed in patent application publication No. CN 201037674Y) have gradually come into the lives of people. The negative ion generator mainly comprises a high-voltage power supply, a negative ion emitting end and a negative ion guiding end. The negative ion emission quantity of the negative ion generator has positive correlation with the voltage, namely the higher the voltage is, the stronger the air ionization capacity of the negative ion emission end is. In order to increase the speed of emitting negative ions by the negative ion generator, it is usually necessary to increase the voltage of the high voltage power supply terminal, but when the voltage of the high voltage power supply is high, a strong corona discharge phenomenon, i.e., a so-called "sparking" phenomenon observed by the naked eyes, is easily generated between the negative ion emitting terminal and the negative ion leading terminal.
Accordingly, there is a need in the art for a new ionizer to solve the above-mentioned problems.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the components in the drawings are illustrated in a certain proportional relationship, the proportional relationship is not constant, and those skilled in the art can make modifications as required to adapt to specific applications, and the modified embodiments will still fall within the scope of the present invention.
It should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1 and 2, the air conditioner of the present invention mainly includes a main body 1 and a negative ion generating device 2. Wherein, the machine body 1 is provided with an air outlet 11. The negative ion generating device 2 mainly includes: a high voltage power supply 21, an anion emission terminal 22 and an anion leading terminal 23. The negative ion emitting terminal 22 and the negative ion leading terminal 23 are electrically connected to the high voltage power supply 21, respectively. The negative ion emitting end 22 and the negative ion leading end 23 are respectively arranged at two sides of the air outlet 11.
As shown in fig. 2, in the preferred embodiment of the present invention, the high voltage power supply 21 is disposed in the main body 1, and the high voltage power supply 21 may be disposed at any position in the main body 1, so that the air conditioner 1 can hide the high voltage power supply 21 in an assembled state, and the air conditioner looks more beautiful as a whole. Or the high voltage power supply 21 may be disposed on the surface or outside of the body 1 as needed by those skilled in the art. The fixed high-voltage power supply 21 is connected to the negative ion emitting terminal 22 and the negative ion leading terminal 23, respectively, via a wire harness.
Further, although not shown in the drawings, the high voltage power supply 21 of the present invention is also electrically connected to a direct current power supply or an alternating current power supply (e.g., a household alternating current power supply). The high voltage power supply 21 can process the input direct current or alternating current through an EMI (electromagnetic interference) processing circuit and a lightning stroke protection circuit, then raise the low voltage to alternating current high voltage through a pulse oscillation circuit, an overvoltage current limiting circuit, a high-low voltage isolation circuit and the like, and then obtain pure direct current negative high voltage through rectification and filtration of special grade electronic materials. And the high voltage power supply 21 delivers the dc negative high voltage to the negative ion emitting terminal 22 through the wire harness. In a preferred embodiment of the present invention, the high voltage power supply 21 and the air conditioner share a power source (e.g., household ac power).
As shown in fig. 1, the negative ion generating device 2 has a plurality of negative ion emitting ends 22, and all the negative ion emitting ends 22 are arranged in line and at equal intervals at the lower side of the air outlet 11 in fig. 1, so that the negative ions emitted from all the negative ion emitting ends 22 can be uniformly distributed at the whole air outlet 11, and the air flow blown out from the air outlet 11 can carry the negative ions. Or, as required, the person skilled in the art may also arrange a plurality of negative ion emitting ends 22 to the lower side of the air outlet 11 at unequal intervals, for example, two negative ion emitting ends 22 adjacent to each other as a group, each group being arranged to the lower side of the air outlet 11 at equal intervals.
In particular, the amount of the solvent to be used,when the negative ion emitting end 22 is connected with the output end of the high voltage power supply 21, a direct current negative high voltage can be obtained, a high voltage electric field is generated between the negative ion emitting end 22 and the negative ion leading end 23 due to the direct current negative high voltage, and a large amount of electrons (e-) are emitted from the negative ion emitting end 22 at a high speed. Since electrons cannot exist in the air for a long time (the existing electrons have the lifetime of only ns grade), the electrons are absorbed by oxygen molecules (O) in the air2) And trapping to generate negative oxygen ions. When being blown out from the air outlet 11, the wind can carry negative oxygen ions to rapidly drift to the whole room, so that the indoor air quality is improved, and the use experience of a user is improved.
With continued reference to fig. 1, the negative ion leading ends 23 are arranged in line at equal intervals on the upper side of the air outlet 11 in fig. 1 corresponding to the positions of the plurality of negative ion emitting ends 22, so that the negative ion leading ends 23 can guide all the negative ions emitted from the negative ion emitting ends 22 to be more uniformly distributed at the whole air outlet 11.
It should be noted that the negative ion leading end 23 can attract electrons emitted from the negative ion emitting end 22 or negative oxygen ions in the air, so that a "loop" is formed among the high voltage power supply 21, the negative ion emitting end 22 and the negative ion leading end 23, and the negative ions are continuously output. Since the electrons emitted from the negative ion emitting terminal 22 cannot be all received by the negative ion leading terminal 23, the "circuit" is not a physical circuit in a strict sense.
In a preferred embodiment of the present invention, the negative ion emitting end 22 has a sharp needle structure, such as a steel sharp needle and a tungsten sharp needle; the negative ion leading end 23 has blunt needle structures, such as blunt needles, corresponding to the negative ion emitting end 22, and each of the blunt needle structures corresponds to a sharp needle structure. Besides, those skilled in the art can also set the negative ion emitting end 22 and the negative ion leading end 23 to be in other forms of structures, such as setting the negative ion emitting end 22 to be a carbon brush, setting the negative ion leading end 23 to be an electrode thin plate or conductive rubber, etc., as required.
As will be understood by those skilled in the art, since the distance between the upper and lower sides of the air outlet 11 is large in fig. 1, the negative ion emitting terminal 22 and the negative ion leading terminal 23 of the present invention have a large distance therebetween, compared to the distance between the negative ion emitting terminal and the negative ion leading terminal of the prior art. Therefore, when the high voltage power supply 21 outputs the same voltage value, the electric field strength between the negative ion emitting terminal 22 and the negative ion leading terminal 23 of the present invention is small. Therefore, the anion generating device 2 can effectively avoid the phenomenon of 'striking sparks' on the premise of ensuring that the emission quantity of anions is not influenced. In addition, the position of the negative ion emitting end 22 and the negative ion guiding end 23 on the air outlet 11 can be properly adjusted by those skilled in the art according to actual needs, so as to increase or decrease the distance between the negative ion emitting end 22 and the negative ion guiding end 23. Or the negative ion emitting end 22 and the negative ion guiding end 23 are replaced in position, so that the negative ion emitting end 22 is located at the upper side of the air outlet 11, and the negative ion guiding end 23 is located at the lower side of the air outlet 11. Or the negative ion emitting end 22 and the negative ion leading end 23 are respectively arranged at the left and right sides of the air outlet 11.
Further, since the electric field intensity between the negative ion emitting terminal 22 and the negative ion leading terminal 23 of the present invention is small when the high voltage power supply 21 outputs the same voltage value as compared with the prior art, a person skilled in the art can increase the negative ion emitting amount of the negative ion generating device 2 by appropriately increasing the output voltage of the high voltage power supply 21.
Furthermore, in a preferred technical solution of the present invention, the negative ion emitting end 22 and the negative ion leading end 23 respectively and completely cover the upper and lower sides of the air outlet 11, so that the negative ions emitted by the negative ion emitting end 22 form a negative ion "waterfall" at the air outlet 11 under the action of the negative ion leading end 23, and the negative ion "waterfall" completely fills the air outlet 11, so that when wind blows out from the air outlet 11, the wind can carry the negative ions (negative oxygen ions), thereby improving the indoor air quality and improving the user experience.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
