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 technique

Negative ions, also known as "active oxygen" or "air vitamins", are as indispensable to human health as sunlight and air. Scientific research shows that the content of negative ions in the air is an important factor in determining the quality of air. The proper amount of negative ions in the air can not only effectively remove dust, sterilize and purify the air, but also activate oxygen molecules in the air to form. Oxygen carrying negative ions have great benefits for the human body's respiratory system and metabolism.

With the improvement of people's quality of life requirements, negative ion generators (such as the negative ion air purification device for air conditioners disclosed in the patent application file of the publication No. CN201037674Y) have gradually entered people's lives. The negative ion generator mainly includes a high voltage power source, a negative ion emitting end and a negative ion guiding end. Negative ion generator negative ion emission has a positive correlation with voltage, that is, the higher the voltage, the stronger the ionizing end of the negative ion emitting end. In order to increase the speed at which the negative ion generator emits negative ions, it is usually necessary to increase the voltage of the high voltage power supply terminal. However, when the voltage of the high voltage power supply is high, a strong corona discharge phenomenon is easily generated between the negative ion emitting end and the negative ion guiding end, that is, we The so-called "firing" phenomenon observed by the naked eye.

detailed description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles 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 drawn in a proportional relationship, the proportional relationship is not constant, and those skilled in the art can adjust them according to needs to adapt to specific applications, and the adjusted technology. The solution will still fall within the scope of protection of the present invention.

It should be noted that in the description of the present invention, the terms "installation", "connected", and "connected" are to be understood broadly, and may be fixed or detachable, for example, unless otherwise explicitly defined and defined. Connected, or integrally connected; can be mechanical or electrical; can be directly connected, or indirectly connected through an intermediate medium, can be the internal communication of the two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood on a case-by-case basis.

As shown in FIGS. 1 and 2, the air conditioner of the present invention mainly includes a body 1 and a negative ion generating device 2. The air outlet 11 is disposed on the body 1. The negative ion generating device 2 mainly includes a high voltage power source 21, a negative ion emitting end 22, and a negative ion leading end 23. The negative ion emitting end 22 and the negative ion guiding end 23 are electrically connected to the high voltage power source 21, respectively. The negative ion emitting end 22 and the negative ion guiding end 23 are respectively disposed at both sides of the air outlet 11.

As shown in FIG. 2, in a preferred embodiment of the present invention, a high voltage power source 21 is disposed in the body 1, and a high voltage power source 21 can be disposed at any position within the body 1, so that the air conditioner 1 is assembled. In a good state, the high-voltage power source 21 can be hidden, so that the air conditioner as a whole looks more beautiful. Alternatively, a person skilled in the art can also set the high voltage power source 21 on the surface or the outside of the body 1 as needed. The fixed high-voltage power source 21 is connected to the negative ion emitting end 22 and the negative ion guiding end 23 through the wire harness, respectively.

Further, although not shown in the drawings, the high voltage power source 21 of the present invention is also electrically connected to a direct current power source or an alternating current power source (e.g., household alternating current). The high-voltage power supply 21 can process the input DC or AC power through the EMI (electromagnetic interference) processing circuit and the lightning protection circuit, and then raise the low voltage to AC high voltage through a pulse oscillation circuit, an overvoltage limiting current, a high voltage and low voltage isolation line, and then pass The special grade electronic material is rectified and filtered to obtain a pure DC negative high voltage. Further, the high voltage power source 21 supplies the DC negative high voltage to the negative ion emitting end 22 through the wire harness. In a preferred embodiment of the present invention, the high voltage power source 21 shares a power source (e.g., household alternating current) with the air conditioner.

As shown in FIG. 1, the negative ion generating device 2 has a plurality of negative ion emitting ends 22, and all of the negative ion emitting ends 22 are arranged in a line at equal intervals on the lower side of the air outlet 11 in FIG. 1 for all negative ions. The negative ions emitted from the emitting end 22 can be evenly distributed throughout the air outlet 11, so that the airflow blown by the air outlet 11 can carry negative ions. Or a person skilled in the art can also provide a plurality of negative ion emitting ends 22 to the lower side of the air outlet 11 in a manner that is not equally spaced and spaced apart from each other as needed, for example, a group of two negative ion emitting ends 22 adjacent to each other. Each set is equally spaced to the lower side of the air outlet 11.

Specifically, the negative ion emitting end 22 can obtain a DC negative high voltage when communicating with the output end of the high voltage power source 21, and a high voltage electric field is generated between the negative ion emitting end 22 and the negative ion guiding end 23 due to a DC negative high voltage, and the negative ion emitting end 22 is discharged at a high speed. A large number of electrons (e-). Since electrons cannot exist in the air for a long time (the electron lifetime is only ns), electrons are trapped by oxygen molecules (O ₂ ) in the air to generate negative oxygen ions. When the wind is blown out from the air outlet 11, the negative oxygen ions can be quickly dispersed to the entire room to improve the indoor air quality, thereby improving the user experience.

With continued reference to Fig. 1, corresponding to the positions of the plurality of negative ion emitting ends 22, the negative ion guiding ends 23 are arranged in a line at equal intervals on the upper side of the air outlet 11 in Fig. 1 so that the negative ion guiding end 23 can be guided. All of the negative ions emitted by the negative ion emitting end 22 are more evenly distributed throughout the air outlet 11.

It should be noted that the negative ion guiding end 23 can attract electrons emitted from the negative ion emitting end 22 or negative oxygen ions in the air to form a "loop" between the high voltage power source 21, the negative ion emitting end 22 and the negative ion guiding end 23, and the negative ions are formed. Continuous output. Since the electrons emitted by the negative ion emitting end 22 cannot all be received by the negative ion guiding end 23, the "loop" 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 pointed needle structure, such as a steel sharp needle and a tungsten sharp needle; and the negative ion guiding end 23 has a blunt needle structure, such as just A blunt needle, and each blunt needle structure corresponds to a pointed needle structure. In addition, those skilled in the art can also set the negative ion emitting end 22 and the negative ion guiding end 23 to other forms of structure, as needed, such as setting the negative ion emitting end 22 as a carbon brush, and setting the negative ion guiding end 23 to Electrode sheet or conductive rubber.

It will be understood by those skilled in the art that since the distance between the upper and lower sides of the air outlet 11 in FIG. 1 is large, compared with the distance between the negative ion emitting end and the negative ion guiding end in the prior art, the present invention There is a large distance between the negative ion emitting end 22 and the negative ion guiding end 23. Therefore, when the high voltage power source 21 outputs the same voltage value, the electric field intensity between the negative ion emitting end 22 and the negative ion guiding end 23 of the present invention is small. Therefore, the negative ion generating device 2 of the present invention can effectively avoid the occurrence of "ignition" phenomenon while ensuring that the amount of negative ion emission is not affected. In addition, those skilled in the art can appropriately adjust the positions of the negative ion emitting end 22 and the negative ion guiding end 23 on the air outlet 11 according to actual needs, thereby increasing or decreasing the distance between the negative ion emitting end 22 and the negative ion guiding end 23. . Alternatively, the negative ion emitting end 22 and the negative ion guiding end 23 are displaced in position such that the negative ion emitting end 22 is located on the upper side of the air outlet 11, and the negative ion guiding end 23 is located on the lower side of the air outlet 11. Alternatively, the negative ion emitting end 22 and the negative ion guiding end 23 are respectively disposed on the left and right sides of the air outlet 11.

Further, since the electric field intensity between the negative ion emitting end 22 and the negative ion guiding end 23 of the present invention is small when the high voltage power source 21 outputs the same voltage value as compared with the prior art, those skilled in the art can appropriately The output voltage of the high voltage power source 21 is increased to increase the negative ion emission amount of the negative ion generating device 2.

Further, in a preferred embodiment of the present invention, the negative ion emitting end 22 and the negative ion guiding end 23 completely cover the upper and lower sides of the air outlet 11, respectively, so that the negative ions emitted from the negative ion emitting end 22 act at the negative ion guiding end 23. Next, a negative ion "waterfall" is formed at the air outlet 11, and the negative ion "waterfall" completely fills the air outlet 11, so that when the wind is blown out from the air outlet 11, it can carry negative ions (negative oxygen ions), improve indoor air quality, and improve The user experience.

Heretofore, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the drawings, but it is obvious to those skilled in the art that the scope of the present invention is obviously not limited to the specific embodiments. Those skilled in the art can make equivalent changes or substitutions to the related technical features without departing from the principles of the present invention, and the technical solutions after the modifications or replacements fall within the scope of the present invention.
