2. Title of invention: Ion generator that reduces ozone generation

Prior Document 2 describes an ion generating device that increases the amount of ion generated while reducing the amount of ozone generated. In particular, a heating unit for increasing the temperature of the ion generating unit by heating the ion generating unit so as to reduce the amount of ozone emitted simultaneously with the ions emitted from the ion generating unit is disclosed.

At this time, in Prior Document 2, only a schematic description of the heating unit is present, and a specific shape thereof is not described. In particular, there is a problem in that it is impossible to simply install the heating unit in the ion generating unit generating ions when a high voltage is applied.

In addition, the ion generating unit of Prior Document 2 corresponds to a fiber discharge unit formed of a plurality of carbon fibers. Since the discharge portion formed of fibers has a relatively large cross-sectional area, there is a problem that the amount of ozone is increased.

That is, the prior document 2 describes a device that is not feasible or extremely difficult to implement, and has a problem that the effect of reducing ozone is unclear.

In order to solve this problem, an object of the present embodiment is to propose an ion generating device and a control method thereof provided in various shapes to reduce the amount of ozone generated.

Another object of the present invention is to provide an ion generating device including a discharge module including a discharge module having a sharp tip portion having a relatively small cross-sectional area and a control method thereof.

In addition, it is an object of the present invention to provide an ion generating device and a control method thereof that are effectively driven by controlling heating and application of a high voltage to a discharge needle according to a dust concentration and a discharge needle temperature.

An ion generating apparatus and a control method thereof according to the idea of the present invention provide a shape and a control method for reducing the amount of ozone generated when ions are generated.

First, looking at the shape of the ion generating device,

The ion generating device includes at least one charging module. The charging module has a circular cross-sectional area and an extended discharge needle to generate ions, and to reduce the ozone generation amount of the discharge needle. A heater coupled to the discharge needle to increase the temperature of the discharge needle is included.

At this time, the discharge needle is provided in a needle shape. That is, the discharge needle is divided into a front end portion extending such that the diameter of the circular cross-sectional area is linearly changed, and a rear end portion having the same diameter of the circular cross-sectional area extending from the front end portion.

And, the heater is coupled to cover the outside of the rear end. The heater may be provided in the discharge needle in various shapes.

In addition, an inner cover or an outer cover for insulation and insulation may be further provided.

On the other hand, looking at the control method of the ion generating device,

In the control method of the ion generating device, when the dust concentration in the air is measured, and when the measured dust concentration exceeds a predetermined first concentration (A), the temperature of the discharge needle is increased at the rear end of the discharge needle. The combined heater is turned on.

And, when the measured dust concentration exceeds the second concentration (B, B>A) corresponding to a value greater than the first concentration (A), the discharge needle is supplied with ions so that ions are generated at the front end of the discharge needle. The step of turning on the high voltage application unit for applying the high voltage is included.

According to the proposed embodiment, as the discharge needle is heated to a predetermined temperature by a heater, it is possible to reduce the amount of ozone generated when ions are generated.

In addition, as the amount of ozone corresponding to a substance that adversely affects the human body is reduced, there is an advantage in that user convenience and reliability can be secured. In addition, there is an advantage in that the space limitation in which the ion generating device is installed disappears.

In addition, there is an advantage in that the amount of ozone generated can be more effectively reduced by the shape of the discharge needle in which ions are generated at the end of the front end portion having a smaller cross-sectional area.

In addition, as the heater is coupled to the rear end extending from the front end, there is an advantage that it can be installed so as not to interfere with the generation of ions. In addition, there is an advantage that insulation and heat dissipation can be achieved by additionally installing an inner cover and an outer cover.

In addition, when the discharge needle does not correspond to a predetermined temperature value at which the amount of ozone generated is reduced, there is an advantage in that the generation of ozone can be prevented by controlling to not apply a high voltage.

In addition, there is an advantage in that the heater is controlled to heat the discharge needle to a predetermined temperature by controlling the heater before reaching a predetermined dust concentration value to which a high voltage is applied, so that ions can be immediately generated if necessary.

1 is a view showing an air conditioner equipped with an ion generating device according to an embodiment of the present invention, and FIG. 2 is a view showing 2-2' of FIG. 1.

1 and 2, the air conditioner 10 according to the idea of the present invention has a case 11 forming an exterior and is coupled to the front of the case 11, and the air conditioner 10 It includes a front panel 12 forming the front exterior.

In the case of a separate air conditioner, the case 11 may be an indoor unit case disposed indoors, and in the case of an integrated air conditioner, the case 11 may be a case of the air conditioner itself. And, in a broad sense, the front panel 12 can be understood as a component of the case 11.

The case 11 includes a suction port 20 through which indoor air is introduced and a discharge port 30 through which air introduced through the suction port 20 is discharged into the indoor space.

The suction port 20 is formed by opening at least a portion of the upper portion of the case 11. In addition, the suction port 20 may be provided with a suction grill 22 for preventing the inflow of foreign matter.

The discharge port 30 may be formed by opening at least a portion of the lower portion of the case 11. In addition, a discharge grill (not shown) may be provided in the discharge port 30.

At one side of the discharge port 30, a discharge vane 32 is installed to be movably provided to open or close the discharge port 30. When the discharge vane 32 is opened, air conditioned in the case 11 may be discharged into the indoor space. For example, the discharge vane 32 may open the discharge port 30 by rotating the lower portion of the discharge vane 32 upward.

In addition, the air conditioner 10 includes a blower fan 60 and a heat exchanger 40 installed inside the case 11.

The heat exchanger 40 is installed to exchange heat with the air sucked through the inlet 20. In addition, the heat exchanger 40 includes a refrigerant tube through which a refrigerant flows and a heat exchange fin coupled with the refrigerant tube to increase a heat exchange area. The heat exchanger 40 is disposed to surround the suction side of the blowing fan 60. For example, the heat exchanger 40 may include a plurality of bent heat exchange units.

The blowing fan 60 includes a cross-flow fan for discharging air sucked in the circumferential direction in the circumferential direction. The blowing fan 60 includes a fan body 61 as a fixing member and a plurality of blades 65 fixed to one side of the fan body 61 and spaced apart in a circumferential direction. The plurality of blades 65 have a shape arranged along the circumferential direction.

Further, the air conditioner 10 is provided with flow path guides 51 and 52 disposed near the outer circumferential surface of the blowing fan 60 to guide the flow of air. The flow path guides 51 and 52 extend along the longitudinal direction of the blower fan 60 and include a rear guide 51 and a stabilizer 52.

The rear guide 51 extends from the rear side of the case 11 to the suction side of the blowing fan 60. This rear guide 51 allows intake air to be smoothly guided toward the blowing fan 60 when the blowing fan 60 is rotated. In addition, the rear guide 51 may prevent the air flowing by the blowing fan 60 from being separated from the blowing fan 60.

The stabilizer 52 is disposed on the discharge side of the blowing fan 60. The stabilizer 52 is installed to be spaced apart from the outer circumferential surface of the blowing fan 60 to prevent the air discharged from the blowing fan 60 from flowing backward to the heat exchanger 40.

In addition, the air conditioner 10 includes a drain portion 53 disposed below the heat exchanger 40. In the drain part 53, condensed water generated during a heat exchange process between air and refrigerant may be stored.

In addition, the air conditioner 10 may include an electric precipitator 70 for collecting dust particles in the air. The electrostatic precipitator 70 may be installed adjacent to the suction port 20 to remove dust particles from sucked air.

The electric dust collecting device 70 includes an ion generating device 100 for generating ions into the air and a dust collecting filter 80 for collecting dust particles charged through the ions generated by the ion generating device 100. . The shape of the electric precipitator shown in FIG. 2 is illustrative and is not limited thereto.

The ion generating device 100 may be disposed in front of the dust collecting filter 80 in a flow direction of air. Referring to FIG. 2, the ion generating device 100 is disposed closer to the suction port 20 than the dust collecting filter 80. Accordingly, dust particles in the air charged by being combined with the ions generated in the ion generating device 100 may be collected by the dust collecting filter 80.

In other words, the ion generating device 100 according to the idea of the present invention may be installed in the air conditioner 10. However, this is exemplary, and the ion generating device 100 may be installed in various products. In addition, the ion generating device 100 may be installed independently to generate ions into the air.

3 is a schematic diagram of an ion generating device according to an embodiment of the present invention. For convenience of explanation, FIG. 3 shows an ion generator and a dust collector together.

As shown in Fig. 3, the ion generating device 100 includes a plurality of charging modules 110. The charging module 110 may be understood as a configuration of an ion generating device that generates ions into the air. The plurality of charging modules 110 may be disposed to be spaced apart from each other to generate ions in one direction.

The dust collecting device 80 includes a plurality of dust collecting plates 82 in which charged dust particles are collected. In addition, the plurality of charging plates 82 are arranged to be spaced apart from each other in correspondence with the plurality of charging modules 110. In particular, the charging module 110 may be disposed between a pair of dust collecting plates 82 disposed adjacent to each other. That is, the charging module 110 and the dust collecting plate 82 may be sequentially disposed.

In particular, the charging module 110 and the dust collecting plate 82 may be installed vertically spaced apart from the flow direction of air. The dust collecting plate 82 may be formed of a conductive plastic. Accordingly, the degree of freedom of the shape may be high and workability may be good.

In addition, the ion generating device 100 includes a charging installation unit 120 in which the plurality of charging modules 110 are installed. The charging installation unit 120 may be understood as a configuration connecting a plurality of charging modules 110 that are disposed to be spaced apart from each other. Accordingly, the charging installation unit 120 may be provided in the shape of a rod extending in the direction in which the charging module 110 is disposed.

In addition, the charging installation unit 120 corresponds to a configuration that is connected to the control unit 130 and the high voltage application unit 140 to be described later. For example, a high voltage may be applied to each of the plurality of charging modules 110 through the charging installation unit 120. Meanwhile, the dust collecting plate 82 may be connected to a ground electrode to collect charged dust particles.

In the above, a case in which a plurality of charging modules 110 are provided has been described, but the ion generating device 100 may include one charging module. That is, the ion generating device 100 includes at least one charging module 110. Hereinafter, one charging module 110 will be described in detail.

4 is a view showing a charging module of the ion generating device according to an embodiment of the present invention.

As shown in FIG. 4, the charging module 110 includes a discharging needle 112 for generating ions at an end. The distal end of the discharge needle 112 may be sharply provided to form a single point. Accordingly, in FIG. 2, each charging module 110 is shown in the shape of a dot.

The discharge needle 112 as a whole has a needle shape, has a circular cross-sectional area and is provided in an extended shape. In this case, the discharge needle 112 may be divided into a front end portion 1120 forming a pointed end and a rear end portion 1122 extending from the front end portion 1120.

In detail, the front end portion 1120 is a portion extending so that the diameter is linearly decreased, and the rear end portion 1122 has the same diameter and may be understood as an extended portion. Accordingly, as shown in FIG. 4, the outside of the front end 1120 is formed to be inclined, and the outside of the rear end 1122 is formed in a straight line.

At this time, the diameter of the rear end 1122 is referred to as the main body diameter T1. In addition, the end of the front end portion 1120 is referred to as an end diameter (T2, T2<T1). That is, the front end 1120 has one end provided with the main body diameter T1, and the other end provided with the distal diameter T2. In addition, the front end portion 1120 is linearly changed in cross-sectional area from the main body diameter T1 to the end diameter T2.

The end of the front end 1120 may be macroscopically understood as a point as described above. However, in reality, the end of the front end 1120 corresponds to a circular cross section having a predetermined diameter. The main body diameter T1 may be provided at least 100 times larger than the distal diameter T2. For example, the distal diameter T2 may be provided with 3 μm, and the body diameter T1 may be provided with 300 μm.

At this time, when ions are generated in the discharge needle 112, ozone may be generated together. The ozone is a substance that adversely affects the human body and it is necessary to minimize the amount of it generated. As the diameter of the portion where ions are generated, that is, the terminal diameter T2 is smaller, the amount of ozone generated may decrease.

The needle shape of the discharge needle according to the idea of the present invention has a smaller diameter than the discharge fibers composed of a bundle of carbon fibers (carbon fib2r). Sleeping, the thickness of one fiber of the discharge fiber corresponds to an average of about 10 μm. On the other hand, the terminal diameter T2 is provided with about 3 μm, so that the ozone generation amount can be effectively reduced.

In addition, the extended length of the rear end 1122 is referred to as a rear end length L1, and the extended length of the front end 1120 is referred to as a front end length L2. That is, the discharge needle 112 extends to a length L1 + L2 that is the sum of the rear end length L1 and the front end length L2. In addition, the rear end length L2 is a length in which the diameter is equally extended, and the front end length L2 corresponds to an extended length such that the diameter is changed.

The rear end length L1 may be the same as the front end length L2 (L1=L2), or may be longer than the front end length L2 (L1>L2). At this time, the rear end length L1 and the front end length L2 are provided larger than the main body diameter T1 (L1, L2> T1).

In addition, the ion generating device 100 according to the idea of the present invention includes a heater 150 for heating the discharge needle 112. The heater 150 may be coupled to the discharge needle 112 to increase the temperature of the discharge needle 112. When the temperature of the discharge needle 112 increases, the amount of ozone generated decreases. That is, the heater 150 is provided to reduce the amount of ozone generated by the discharge needle 112.

The heater 150 may be disposed to surround the rear end 1122. As shown in FIG. 4, the heater 150 may be provided in a cylindrical shape coupled to cover the outside of the rear end 1122. In particular, the heater 150 may be provided in a cylindrical shape extending to the heater length L3.

In this case, the heater length L3 may be equal to the rear length L1 (L1=L3), or may be longer than the rear length L1 (L3>L1). When the heater length L3 and the rear end length L1 are the same, the heater 150 is coupled to completely cover the outside of the rear end 1122. That is, the heater 150 is coupled to the rear end 1122 so as not to protrude from the rear end 1122 to one side.

Hereinafter, operation of the heater 150 and control of the ion generating device 100 will be described in detail.

5 is a view showing a control configuration of the ion generating device according to an embodiment of the present invention.

As shown in FIG. 5, the ion generating apparatus 100 according to the idea of the present invention includes a control unit 130. The controller 130 may control each component by signals input from the power supply unit 160 and the sensing units 170 and 180.

In this case, the control unit 130 may correspond to a control unit of a product in which the ion generating device 100 is installed. For example, the control unit 130 may correspond to a control unit of the air conditioner 10 in which the ion generating device 100 is installed. In this case, only the configuration related to the ion generating device 100 is illustrated in FIG. 5, but the controller 130 may control the ion generating device 100 together with the configuration of the air conditioner 10.

In particular, the power supply unit 160 may correspond to a configuration in which ON/OFF of the air conditioner 10 is input. Also, a heating or cooling mode, a set temperature, and an air volume may be input. For example, when strong wind is input through the power supply unit 160, the control unit 130 may rotate the blowing fan 60 at high speed.

In this case, the ion generating device 100 may be turned ON/OFF together with ON/OFF of the air conditioner 10. In addition, the power supply unit 160 may be provided with a configuration that turns on/off the ion generating device 100 separately from the air conditioner 10. For example, an air cleaning mode or an electric dust collection mode may be input through the power supply 160 to turn on the ion generating device 100.

Various types of sensors may be provided in the sensing units 170 and 180. For example, the sensing unit may be provided with a dust sensor 170 that measures the concentration of dust in the air. For example, the dust sensor 170 may be installed in the suction grill 22 of the air conditioner 10 to measure the concentration of dust in the air flowing into the air conditioner 10. At this time, the value measured by the dust sensor 170 is referred to as the dust concentration (X).

In addition, the sensing unit includes a temperature sensor 180 that measures the temperature of the discharge needle 112. In particular, the temperature sensor 180 may be installed at the rear end 1122 coupled to the heater 150. At this time, the temperature value measured by the temperature sensor 180 is referred to as the discharge needle temperature (T).

The control unit 160 may turn on/off the heater 150 and the high voltage application unit 140. In particular, the control unit 160 may turn on/off the heater 150 and the high voltage applying unit 140 according to the dust concentration X and the discharge needle temperature T measured by the sensing unit. Hereinafter, this will be described in detail.

6 is a view showing a control condition of the ion generating device according to an embodiment of the present invention.

As shown in FIG. 6, the heater 150 and the high voltage applying unit 140 are ON/OFF controlled according to the measured dust concentration X and the discharge needle temperature T. For convenience of description, in FIG. 6, ON/OFF control of the heater 150 is described as heater ON and heater OFF, and ON/OFF control of the high voltage application unit 140 is illustrated as high voltage ON and high voltage OFF.

At this time, the dust concentration (X) and the discharge needle temperature (T) may be divided into a plurality of sections according to the measured values. The section according to the dust concentration (X) is described horizontally, and the section according to the discharge needle temperature (T) is described vertically.

The dust concentration X may be divided into a first concentration A and a second concentration B stored in advance. The first concentration (A) and the second concentration (B) correspond to random values separated to measure the degree of pollution in the air. In this case, the second concentration (B) corresponds to a value greater than the first concentration (A) (B>A).

Specifically, 1) when the dust concentration (X) is less than or equal to the first concentration (A), 2) when the dust concentration (X) exceeds the first concentration (A) and is less than or equal to the second concentration (B) And 3) when the dust concentration (X) exceeds the second concentration (B).

In this case, the second concentration B corresponds to a value when there are relatively many dust particles in the air. Specifically, when the dust concentration in the air reaches the second concentration (B), it corresponds to a case where the removal of dust particles is required. Accordingly, when the dust concentration X exceeds the second concentration B, the high voltage applying unit 140 may be turned on.

Meanwhile, the first concentration A corresponds to a value when there are relatively few dust particles in the air. Specifically, when the dust concentration in the air reaches the first concentration (A), it corresponds to a case where the removal of dust particles is not yet necessary. However, when it is determined that there is a certain degree of dust concentration in the air, a preheating step to be described later may be performed.

The discharge needle temperature T may be divided into a first temperature T1 and a second temperature T2 stored in advance. The first temperature T1 and the second temperature T2 correspond to arbitrary values. In this case, the second temperature T2 corresponds to a value greater than the first temperature T1 (T2>T1).

Specifically, 1) when the discharge needle temperature (T) is less than the first temperature (T1), 2) the discharge needle temperature (T) exceeds the first temperature (T1) and the second temperature (T2) It is classified into the following cases and 3) the case where the discharge needle temperature T exceeds the second temperature T2.

In this case, the first temperature T1 corresponds to a temperature at which the amount of ozone generated in the discharge needle 112 is reduced. Specifically, when the discharge needle 112 reaches a certain temperature or higher, the amount of ozone generated during discharge is rapidly reduced. The first temperature T1 may be set to a specific value at which the amount of ozone is reduced according to experiments and designs.

Accordingly, when the discharge needle temperature T is less than or equal to the first temperature T1, the high voltage applying unit 140 is maintained in an OFF state. That is, only when it is determined that the amount of ozone generated by the discharge needle 112 is small, the discharge needle 112 is controlled to generate ions.

Meanwhile, the second temperature T2 may be understood as a temperature value for safety. When the temperature of the discharge needle 112 is too high, safety problems such as insulation breakdown may occur. In addition, this is because a problem may occur in a product in which the ion generating device 100 is installed.

In summary, when the dust concentration X is less than or equal to the first concentration A, the heater 150 and the high voltage applying unit 140 are both OFF-controlled. It can be understood that when the dust concentration X is less than or equal to the first concentration A, the ion generating device 100 is turned off.

And, when the dust concentration (X) exceeds the first concentration (A), the heater 150 is turned on. At this time, the high voltage applying unit 140 is controlled to be OFF. However, when the discharge needle temperature T exceeds the second temperature T2, the heater 150 is also turned off.

In addition, when the dust concentration (X) exceeds the second concentration (B), the high voltage applying unit 140 is turned ON. At this time, the heater 150 is maintained in the ON state as long as the discharge needle temperature T does not exceed the second temperature T2. However, when the discharge needle temperature T is less than or equal to the first temperature T1, the high voltage application unit 140 is not turned on.

That is, the first concentration A may be understood as a value at which the heater 150 is turned ON. In addition, the second concentration B may be understood as a value at which the high voltage application unit 140 is turned ON. However, when the second temperature T2 is exceeded, the heater 150 is turned off, and when the first temperature T1 is not reached, the high voltage applying unit 140 is not turned on.

Such control conditions are exemplary, and the ion generating device may be controlled in various forms. In particular, the ion generating device may be controlled in conjunction with an installed product.

The ion generating apparatus according to the spirit of the present invention may include various types of charging modules. Hereinafter, each embodiment will be described, and the same reference numerals are used for the same configuration, and all descriptions thereof are cited. In addition, configurations modified according to the embodiment are identified by denoting a, b, c, and d in reference numerals.

As shown in FIG. 7, the charging module 110a according to the first embodiment includes a discharge needle 112a and a heater 150a. The discharge needle 112a is divided into a front end portion 1120a and a rear end portion 1122a, and the shape of the discharge needle 112a is referred to as described above and a description thereof is omitted.

The heater 150a is disposed so as to cover at least a portion of the rear end 1122a and surround the outside of the rear end 1122a. In this case, when the heater 150a and the rear end 1122a directly contact each other, electricity may be conducted. That is, a high voltage applied to the discharge needle 112a may be transmitted to the heater 150a.

To prevent this, the charging module 110a includes an inner cover 1130 disposed between the discharge needle 112a and the heater 150a. The inner cover 1130 is disposed to surround the outside of the rear end 1122a. In addition, the heater 150a is disposed to surround the outside of the inner cover 1130.

Accordingly, the rear end 1122a, the inner cover 1130, and the heater 150a may be sequentially disposed as shown in FIG. 7B. In other words, the inner cover 1130 is coupled to cover at least a portion of the rear end 1122a, and the heater 150a is coupled to cover at least a portion of the inner cover 1130.

The inner cover 1130 and the heater 150a may be provided in a cylindrical shape extending to a predetermined length. In addition, the inner cover 1130 may be provided in the form of a tape that is bonded to and bonded to the outside of the rear end 1122a.

In addition, an outer cover 1150 to be described later may be further provided on the charging module 110a.
