Description

Technical Field

[0001] The utility model relates to the technical field of negative ion purification, in particular to a negative ion generating device and an air conditioner with the negative ion generating device. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for indoor air, and need a fresher indoor air environment. Negative ions, which are highly active and have a long natural diffusion distance, combine with positively charged particles such as bacteria, dust, and smoke in the air, and condense into balls and fall to the ground, thereby playing a role in sterilization and eliminating the odor produced by harmful gases. In air containing high concentrations of negative ions, dust, bacteria, viruses, etc. with a diameter of less than 1 micron are almost zero.

[0003] In addition, negative ions can react with toxic gases in the air, turning them into non-toxic or low-toxic substances. For example, when formaldehyde meets negative ions, it can decompose into carbon dioxide and water.

[0004] Although negative ions have sterilization and disinfection functions, they will produce a certain amount of ozone and have a dust collection effect, so the higher the concentration is not necessarily better. However, the concentration of negative ion modules produced by manufacturers is relatively fixed and users cannot adjust it. Therefore, in a small space, when the negative ion module is working, some people feel a peculiar smell or dust is easily generated around the home appliances where the negative ion module is installed. Or in a larger space, reliable sterilization and disinfection cannot be achieved due to the relatively low concentration of negative ions.

[0005] In addition, most existing negative ion modules provide a transmitter head wrapped in a plastic shell, which requires the user to design a separate installation structure during installation, which is inconvenient for users.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0075] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0076] The present application relates to a negative ion generating device, which can generate negative ions. The negative ions are mixed with air and can purify the air (for example, sterilize and disinfect). Therefore, the negative ion generating device can also be installed in the indoor unit of the air conditioner.

[0077] When a negative ion generating device is configured in the indoor unit, the negative ion generating device emits negative ions, and the negative ions can pass through the air outlet 310 (see Fig.11 ) into the indoor air.

[0078] The basic working principle of the air conditioner is introduced below.

[0079] See also Figure 1 , the air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, condenser, expansion valve and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0080] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0081] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0082] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0083] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0084] See also Figure 2 , which shows the refrigerant flow direction when the air conditioner is in cooling operation.

[0085] The compressor compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure state, which enters the outdoor heat exchanger. After heat exchange in the outdoor heat exchanger, it condenses and releases heat to become liquid refrigerant. The refrigerant then passes through the throttling element and enters the indoor side.

[0086] The refrigerant entering the indoor heat exchanger on the indoor side evaporates and absorbs heat, turning into gas. The refrigerant coming out of the indoor heat exchanger is finally sucked into the compressor for compression, completing the refrigeration cycle.

[0087] See also Figure 3 , which shows the refrigerant flow direction when the air conditioner is in heating operation.

[0088] The compressor compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure state and enters the indoor heat exchanger.

[0089] After heat exchange inside the indoor heat exchanger, it condenses and releases heat to become liquid refrigerant. The refrigerant is then throttled to a low-temperature and low-pressure gas-liquid state through a throttling element. The two-phase refrigerant enters the outdoor heat exchanger, evaporates, absorbs heat, and becomes gaseous.

[0090] The refrigerant coming out of the outdoor heat exchanger is finally sucked into the compressor for compression, completing the heating cycle.

[0091] As follows, the structure of the negative ion generating device will be introduced.

[0092] In some embodiments of the present application, the negative ion generating device includes a power supply module 100 .

[0093] The power supply module 100 provides negative high voltage to the ion emitting needle 250 in the negative ion generating device, thereby generating negative ions at the tip of the ion emitting needle 250 .

[0094] In some embodiments of the present application, see Figure 4 The power supply module 100 includes a power control module 110 , a boost module 120 and a rectifier module 130 .

[0095] The power control module 110 can adjust the voltage of the AC power input to the boost module 120 . The boost module 120 boosts the input voltage to the required high voltage signal, which is rectified to a negative voltage by the rectifier module 130 to supply the ion emission needle 250 .

[0096] In some embodiments of the present application, the power control module 110 has a built-in sliding rheostat RT, which is user-adjustable. By adjusting the resistance of the sliding rheostat RT, the voltage input to the boost module 120 can be adjusted, so that the voltage input to the boost module 120 varies within a certain range.

[0097] In some embodiments of the present application, the power control module 110 controls and adjusts the output voltage of the emission end of the ion emission needle 250 to vary between -1 KV and -5 KV.

[0098] The AC power L line is connected to the boost module 120 through a first current limiting resistor R1 and a sliding rheostat RT connected in series, and the AC power N line is connected to the ground of the boost module 120 through a second current limiting resistor R2.

[0099] The output end of the boost module 120 is connected to the ion emission needle 250 through the rectifier module 130 , and the ground end of the boost module 120 is connected to the ground end through the first safety isolation resistor R3 and the second safety isolation resistor R4 connected in series.

[0100] The grounding terminal may be a ground wire or a grounding sheet metal of a device using the negative ion generating device.

[0101] The first safety isolation resistor R3 and the second safety isolation resistor R4 ensure that the ground wire at the rear end remains electrically connected to the entire circuit at the front end while ensuring its safety performance. Even if the ground wire of the device using the negative ion generating device itself is not reliably connected, it can ensure that the machine casing and other parts of the device will not cause safety hazards due to the negative ion charge.

[0102] By adjusting the resistance of the sliding rheostat RT, the voltage input to the boost module 120 can be changed, thereby changing the negative high voltage supplied to the ion emitting needle 250 , and further adjusting the concentration of negative ions emitted by the ion emitting needle 250 .

[0103] In some embodiments of the present application, the resistance adjustment of the sliding resistor RT can be operated by the user, so that the user can flexibly adjust the negative ion concentration according to different needs or different scenarios.

[0104] In order to facilitate the installation of the ion emitting needle 250, in some embodiments of the present application, the installation structure of the ion emitting needle 250 is designed to achieve convenient installation while avoiding safety hazards caused by high voltage.

[0106] The negative ion generator 200 is powered by the negative high voltage output by the power supply module 100 , and can emit negative ions at the emission end of the ion emission needle 250 of the negative ion generator 200 .

[0107] In some embodiments of the present application, the negative ion generator 200 includes a housing 230 , an isolation portion 220 , a mounting portion 210 and an ion emission needle 250 .

[0110] In some embodiments of the present application, the housing 230 and the mounting portion 210 are placed in a straight line on both sides of the isolation portion 220 to reduce the installation space of the negative ion generator 200 .

[0111] The high voltage-resistant wire 240 electrically connects the negative high voltage and the power supply end of the ion emission needle 250 .

[0112] The power supply end and the emission end of the ion emission needle 250 are respectively located at two opposite ends of the ion emission needle 250 .

[0113] Correspondingly, see Figure 5 In order to emit the negative ions generated by the emission end of the ion emission needle 250 , a release port 232 corresponding to the emission end is opened in the shell 230 , and the negative ions emitted by the ion emission needle 250 are released through the release port 232 .

[0114] The mounting portion 210 is used to mount the negative ion generator 200 on a device or a fixed platform.

[0115] In some embodiments of the present application, a high-voltage resistant wire 240 is provided in the mounting portion 210, and an ion emitting needle 250 is provided in the shell 230.

[0116] In some embodiments of the present application, in order to fix the high voltage wire 240 and the ion emission needle 250 and prevent the wire from shaking and bending frequently, resulting in an unreliable electrical connection position with the ion emission needle 250, see Figure 6 and Figure 7 The isolation portion 220 is provided with a first through portion 221 , a second through portion 222 and a third through portion 223 which penetrate each other.

[0120] Afterwards, glue is poured into the installation portion 210 to achieve the purpose of fixing the high-voltage-resistant wire 240 .

[0121] In some embodiments of the present application, the high-voltage-resistant wire 240 and the ion emitting needle 250 may also be fixed in the mounting portion 210 , so that a larger space may be reserved in the shell 230 to facilitate the ion emitting needle 250 to emit negative ions.

[0122] See also Figure 6 and Fig. 9 The mounting portion 210 is provided with a first mounting through portion 211 and a second mounting through portion 212 which are T-shaped and penetrate through.

[0123] The cross-sectional area of ​​the first installation through-portion 211 is greater than that of the second installation through-portion 212 , wherein the cross-sectional area of ​​the second installation through-portion 212 is substantially equal to the cross-sectional area of ​​the ion emitting needle 250 , thereby preventing the ion emitting needle 250 from shaking when in the second installation through-portion 212 .

[0124] See also Figure 5 The high voltage resistant wire 240 is arranged in the first installation through-portion 211 .

[0125] After the power supply end of the ion emitting needle 250 passes through the shell 230 and the second through-hole 222 of the isolation part 220 and the second installation through-hole 212 of the installation part 210, it extends into the first installation through-hole 211 and is connected to the high-voltage wire 240, that is, the connection position between the high-voltage wire 240 and the power supply end is located in the first installation through-hole 211.

[0126] The cross-sectional area of ​​the second through portion 222 is also substantially equal to the cross-sectional area of ​​the ion emitting needle 250 .

[0127] Afterwards, glue is poured into the first installation through-hole 211 to fix the high-voltage-resistant wire 240 and the ion emitting needle 250 .

[0128] In some embodiments of the present application, the power supply ends of the high voltage resistant wire 240 and the ion emission needle 250 are electrically connected by welding.
