Referring to FIGS. 1 and 2, a control method of an embodiment of the present invention is used to control the air conditioner 10. The air conditioner 10 includes an ionizer 17. Control methods include:

Step S10: acquiring actual air quality in the room; and

Step S20: The operating voltage of the ion generator 17 is controlled according to the difference between the actual air quality and the set air quality.

Referring to FIG. 2, the controller 30 of the embodiment of the present invention is used to control the air conditioner 10. The air conditioner 10 includes an ionizer 17. The controller 30 includes an acquisition device 32 and a control device 34. The control method of the embodiment of the present invention can be implemented by the controller 30 of the embodiment of the present invention. For example, step S10 can be implemented by acquisition device 32, which can be implemented by control device 34.

That is, the acquisition device 32 can be used to capture the actual air mass in the room. Control device 34 can be used to control the operating voltage of ion generator 17 based on the difference between the actual air mass and the set air mass.

The controller 30 of the embodiment of the present invention can be applied to the air conditioner 10 of the embodiment of the present invention. That is, the air conditioner 10 of the embodiment of the present invention includes the controller 30 of the embodiment of the present invention. The air conditioner 10 of the embodiment of the present invention further includes an ionizer 17.

Referring to FIG. 3, an air conditioner 10 of an embodiment of the present invention includes an ionizer 17, one or more processors 40, a memory 50, and one or more programs. One or more of the programs are stored in memory 50 and are configured to be executed by one or more processors 40. The program includes instructions for performing the following steps:

Step S10: acquiring actual air quality in the room; and

The control method, the controller 30, and the air conditioner 10 according to the embodiment of the present invention control the operating voltage of the ionizer 17 based on the difference between the actual air mass and the set air mass, thereby being capable of adjusting the cleanliness of the indoor air.

Specifically, an air quality sensor can be installed indoors. Air quality sensors are used to detect air quality in the room in real time. One way is that the air quality sensor is arranged independently of the air conditioner 10, and the acquisition device 32 can communicate with the air quality sensor to obtain the actual air quality detected by the air quality sensor. Alternatively, the acquisition device 32 is an air quality sensor, at which time the air quality sensor is part of the air conditioner 10.

The air quality can be set to the air quality set by the user (for example, the air quality that the user inputs through the input interface) or the standard value of the healthy air quality defined by the relevant organization. Air quality can be assessed by the value of the API. Generally, the air pollution index ranges from 0 to 500. When the value of the air pollution index is larger, the air quality is worse. In one example, the air mass is set to 80 and the actual air mass acquired by the acquisition device 32 is 100. The control unit 34 controls the operating voltage of the ionizer 17 based on the difference between the actual air mass and the set air mass (i.e., 20).

The ionizer 17 is used to generate positive ions and/or negative ions to purify the air. The ion generator 17 may be a negative ion generator 17, or a positive ion generator 17, or a positive and negative ion generator 17. It will be appreciated that negative ion generator 17 is used to generate negative ions, positive ion generator 17 is used to generate positive ions, and positive and negative ion generators 17 are used to generate positive and negative ions. The type of ion generator 17 can be selected according to actual conditions. When the operating voltage of the ionizer 17 is increased, the ion generator 17 will generate more positive ions and/or negative ions per unit time, thereby enhancing the air purification effect.

When the actual air mass is greater than the set air mass, the control device 34 boosts the operating voltage of the ionizer 17 based on the difference between the actual air mass and the set air mass. For example, when the actual air mass is 100 and the air mass is set to 80, the operation of the ionizer 17 When the voltage is V1, the control unit 34 controls the voltage of the ionizer 17 to be raised from V1 to V2. When the difference between the actual air mass and the set air mass is larger, the control device 34 increases the magnitude of the operating voltage of the ionizer 17 to a greater extent. Within a certain range, the operating voltage of the ionizer 17 is positively correlated with the difference between the actual air mass and the set air mass. It can be understood that the operating voltage of the ionizer 17 should be less than or equal to the limit voltage of the ionizer 17. The limit voltage of the ion generator 17 is the highest voltage value at which the ionizer 17 can operate normally. In some embodiments, the limit voltage of the ionizer 17 can be determined based on the material, structure, process, etc. of the ionizer 17, and the ionizer 17 can be calculated to obtain a limit voltage based on a large number of experiments or related formulas before leaving the factory. When the control device 34 has increased the operating voltage of the ionizer 17 to the limit voltage based on the difference between the actual air mass and the set air mass, the operating voltage of the ionizer 17 will no longer increase.

When the actual air mass is less than the set air mass, the control device 34 lowers the operating voltage of the ionizer 17 based on the absolute value of the difference between the actual air mass and the set air mass. For example, when the actual air mass is 60, the set air mass is 80, and the operating voltage of the ionizer 17 is V1, the control device 34 controls the voltage of the ionizer 17 to be lowered from V1 to V3. Thus, an increase in ozone in the indoor air due to the generation of a large amount of ions by the ion generator 17 can be reduced. When the absolute value of the difference between the actual air mass and the set air mass is larger, the control device 34 lowers the magnitude of the operating voltage of the ion generator 17. Within a certain range, the operating voltage of the ionizer 17 is inversely related to the absolute value of the difference between the actual air mass and the set air mass.

Referring to Figures 4 and 5, in certain embodiments, the air conditioner 10 further includes a fan 14. Control methods also include:

Step S30: Control the rotation speed of the fan 14 according to the difference between the actual air quality and the set air quality.

Referring to FIG. 5, in some embodiments, the air conditioner 10 further includes a fan 14. Step S30 can be implemented by control device 34.

That is to say, the control device 34 can also be used to control the rotational speed of the blower 14 based on the difference between the actual air mass and the set air mass.

In certain embodiments, the air conditioner 10 also includes a blower 14. The program also includes instructions for performing the following steps:

Specifically, as the rotational speed of the fan 14 is larger, the rate of air circulation is faster, so that the speed of air purification can be accelerated, so that the actual air quality approaches the set air quality as quickly as possible.

When the actual air mass is greater than the set air mass, the control device 34 increases the speed of the fan 14 based on the difference between the actual air mass and the set air mass. For example, when the actual air mass is 100, the set air mass is 80, and the speed of the fan 14 is R1, the control device 34 controls the speed of the fan 14 to be raised from R1 to R2. When the difference between the actual air mass and the set air mass is larger, the amplitude of the rotational speed of the fan 14 by the control device 34 is increased. Within a certain range, the rotational speed of the fan 14 is positively correlated with the difference between the actual air mass and the set air mass. It can be understood that the rotational speed of the fan 14 should be less than or equal to the limit rotational speed of the fan 14. The limit rotation speed of the fan 14 is the maximum rotation speed at which the fan 14 can work normally. In some embodiments, the limit speed of the fan 14 can be determined based on the material, structure, process, etc. of the fan 14, and the fan 14 can be calculated to obtain the limit speed based on a large number of experiments or related formulas before leaving the factory. When the control device 34 has increased the rotational speed of the blower 14 to the limit rotational speed based on the difference between the actual air mass and the set air mass, the rotational speed of the blower 14 will no longer increase.

When the actual air mass is less than the set air quality, the control device 34 is based on the difference between the actual air quality and the set air quality. The value reduces the rotational speed of the fan 14. For example, when the actual air mass is 60, the set air mass is 80, and the speed of the fan 14 is R1, the control unit 34 controls the speed of the fan 14 to be lowered from R1 to R3. In this way, noise during operation of the air conditioner 10 due to a large rotation speed of the fan 14 can be reduced. When the absolute value of the difference between the actual air mass and the set air mass is larger, the control device 34 reduces the magnitude of the rotational speed of the fan 14 to a greater extent. Within a certain range, the rotational speed of the fan 14 is inversely related to the absolute value of the difference between the actual air mass and the set air mass.

In some embodiments, step S20 and step S30 are performed simultaneously, that is, the controller 30 controls the operating voltage of the ionizer 17 and controls the rotational speed of the fan 14 according to the difference between the actual air mass and the set air mass. .

In this way, the air purification rate and air purification effect are further accelerated.

Referring to FIGS. 6 and 7 , in some embodiments, the air conditioner 10 further includes a compressor 19 . Control methods also include:

Step S40: acquiring an actual air temperature in the room; and

Step S50: Control the power of the compressor 19 according to the difference between the actual air temperature and the set air temperature.

Referring to FIG. 7, in some embodiments, the air conditioner 10 further includes a compressor 19. Step S40 can be implemented by acquisition device 32, which can be implemented by control device 34.

That is to say, the acquisition device 32 can also be used to acquire the actual air temperature in the room. Control device 34 can also be used to control the power of compressor 19 based on the difference between the actual air temperature and the set air temperature.

In certain embodiments, the air conditioner 10 also includes a compressor 19. The program also includes instructions for performing the following steps:

Step S40: acquiring an actual air temperature in the room; and

Specifically, an air temperature sensor can be installed indoors. The air temperature sensor is used to detect the air temperature in the room in real time. One way is that the air temperature sensor is provided independently of the air conditioner 10, and the acquisition device 32 can communicate with the air quality sensor to obtain the actual air temperature detected by the air temperature sensor. Alternatively, the acquisition device 32 is an air temperature sensor, at which time the air quality sensor is part of the air conditioner 10.

Set the air temperature to the air temperature set by the user (for example, the air temperature that the user inputs through the remote control). In one example, the set air temperature is 22 ° C and the actual air temperature obtained by the acquisition device 32 is 24 °C. Control device 34 controls the power of compressor 19 based on the difference between the actual air temperature and the set air temperature (i.e., 2 °C).

Controlling the power of the compressor 19 can be accomplished by controlling the power of the motor of the compressor 19. It can be understood that the greater the power of the compressor 19, the better the cooling or heating effect of the air conditioner 10. The power of the commissioning compressor 19 is useful to speed up the increase or decrease the actual air temperature so that the actual air temperature tends to set the air temperature as quickly as possible.

When the actual air temperature is greater or less than the set air temperature, the control device 34 boosts the power of the compressor 19 based on the absolute value of the difference between the actual air temperature and the set air temperature. For example, when the actual air temperature is 24 ° C or 20 ° C, the set air temperature is 22 ° C, and the power of the compressor 19 is P1, the control device 34 controls the power of the compressor 19 to be raised from P1 to P2. The greater the magnitude of the power of the control device 34 to lift the compressor 19 as the absolute value of the difference between the actual air temperature and the set air temperature is greater. Within a certain range, the compressor The power of 19 is positively correlated with the absolute value of the difference between the actual air temperature and the set air temperature. It will be appreciated that the power of the compressor 19 should be less than or equal to the ultimate power of the compressor 19. Among them, the ultimate power of the compressor 19 is the highest power at which the compressor 19 can operate normally. In some embodiments, the ultimate power of the compressor 19 can be determined based on the material, structure, process, etc. of the compressor 19, and the compressor 19 can be calculated to obtain the ultimate power based on a large number of experiments or related formulas prior to shipment. When the control device 34 has increased the power of the compressor 19 to the limit power based on the absolute value of the difference between the actual air temperature and the set air temperature, the power of the compressor 19 will no longer increase.

It can be understood that the control device 34 can control the power reduction of the compressor 19 when the difference between the actual air temperature and the set air temperature is small (e.g., approaching zero) after the power of the compressor 19 is adjusted by the control device 34. The power to the compressor 19 during normal operation to save energy loss.

The controller 30 of the embodiment of the present invention controls the operating voltage of the ion generator 17 according to the difference between the actual air quality and the set air quality, and controls the power of the compressor 19 according to the difference between the actual air temperature and the set air temperature, so that the air conditioner The device 10 can simultaneously adjust the temperature and cleanliness of the room.

Referring to Figures 8 and 9, in some embodiments, the air conditioner 10 further includes a fan 14. Control methods also include:

Step S60: controlling the rotation speed of the fan 14 according to the difference between the actual air temperature and the set air temperature, and the difference between the actual air quality and the set air quality.

Referring to FIG. 9 , in some embodiments, the air conditioner 10 further includes a fan 14 . Step S60 can be implemented by control device 34.

That is to say, the control device 34 can also be used to control the rotational speed of the fan 14 based on the difference between the actual air temperature and the set air temperature, and the difference between the actual air mass and the set air mass.

Specifically, as the rotational speed of the blower 14 is larger, the rate of air circulation is faster, so that the air purification rate and the temperature adjustment speed can be accelerated.

When the actual air temperature is greater than or less than the set air temperature, the control device 34 increases the rotational speed of the fan 14 based on the absolute value of the difference between the actual air temperature and the set air temperature. For example, when the actual air temperature is 24 ° C or 20 ° C, the set air temperature is 22 ° C, and the rotational speed of the fan 14 is R1, the control device 34 controls the speed of the fan 14 to be raised from R1 to R2. When the absolute value of the difference between the actual air temperature and the set air temperature is larger, the amplitude of the rotational speed of the fan 14 by the control device 34 is increased. Within a certain range, the rotational speed of the fan 14 is positively correlated with the absolute value of the difference between the actual air temperature and the set air temperature. It can be understood that the rotational speed of the fan 14 should be less than the limit rotational speed of the fan 14. When the control device 34 has increased the rotational speed of the blower 14 to the limit rotational speed based on the absolute value of the difference between the actual air temperature and the set air temperature, the rotational speed of the blower 14 will no longer increase.

It can be understood that when the difference between the actual air temperature and the set air temperature is small (such as approaching 0) after the speed of the fan 14 is adjusted by the control device 34, the control device 34 can control the speed of the fan 14 to be reduced to the fan. 14 The speed of normal operation to reduce noise.

The control device 34 controls the rotation speed of the fan 14 according to the difference between the actual air quality and the set air quality, and the implementation of step S30 The manner is the same or similar, and the description will not be repeated here.

When the rotation speed of the fan 14 is controlled according to the difference between the actual air temperature and the set air temperature, and the control command for controlling the rotation speed of the fan 14 according to the difference between the actual air quality and the set air quality is inconsistent (for example, according to the actual air temperature and Setting the difference of the air temperature needs to increase the rotation speed of the fan 14, and according to the difference between the actual air quality and the set air quality, it is required to reduce the rotation speed of the fan 14, and the controller 30 can preferentially set the air temperature according to the actual air temperature. The difference controls the rotational speed of the fan 14, thus ensuring that the user feels a comfortable air temperature when using the air conditioner 10. In addition, the controller 30 can adjust the cleanliness of the indoor air by raising the voltage of the ionizer 17 at this time.

Referring to FIG. 10, a computer readable storage medium 60 of an embodiment of the present invention includes a computer program for use with the air conditioner 10. The computer program can be executed by processor 40 to perform the control method of any of the above embodiments.

For example, a computer program can be executed by processor 40 to complete the control method of the following steps:

Step S10: acquiring actual air quality in the room; and

Referring to Figures 11-13, the control method and controller 30 of the embodiment of the present invention can be applied to an air conditioner 10 having the following structure. The air conditioner 10 is formed with an air inlet port 11. The air conditioner 10 further includes a purification screen 12 for purifying air disposed near the air inlet 11. The purification screen 12 includes an electrostatic electret filter 122 or an active electrostatic precipitator screen 124. The air temperature sensor and the air quality sensor may be disposed at a place where indoor air circulates, or may be disposed inside the air conditioner 10.

It should be noted that when the purification filter 12 includes the electrostatic electret filter 122 or the active electrostatic waste filter 124, the electrostatic electret filter 122 and the active electrostatic waste filter 124 can be removed for cleaning or replacement.

Referring to Figure 12, in some embodiments, the electrostatic electret filter 122 utilizes an electrostatic electret material.

Specifically, the electrostatic electret material has high bulk resistance and surface resistance, high dielectric breakdown strength, low hygroscopicity, etc., and can store space charge or dipole charge for a long period of time without external power input, thereby utilizing charge static Electricity captures dust particles in the air.

In one example, the electrostatic electret filter 122 includes a strip of static electret material. The electrostatic electret filter 122 collects dust by a nonwoven fabric in which strip-shaped electrostatic electret materials are intermittently laid. The electrostatic electret filter 122 formed by the electrostatic electret material has the advantages of low wind resistance, high filtration efficiency, high dust holding capacity, antibacterial, etc., and can effectively filter particulate pollutants such as dust, dander, pollen, bacteria and the like in the air.

The electrostatic electret material in the embodiment of the present invention is mainly composed of high polymer, including polypropylene, polytetrafluoroethylene, hexafluoroethylene/polytetrafluoroethylene copolymer, polytrifluoroethylene, polypropylene (blend) and Polyester, etc.

Referring to Figure 13, in some embodiments, the active electrostatic precipitator screen 124 includes a vacuum electrode.

Specifically, the dust suction electrode captures dust particles in the air by Coulomb force.

In one example, the vacuum electrode includes a positive electrode and a negative electrode connected to a power source. The positive electrode and the negative electrode are alternately arranged to form a plurality of electric field regions. Under the action of an electric field, air molecules are ionized into positive ions and electrons. The dust particles are negatively charged in combination with electrons and are attracted to the positive electrode to be trapped.

In some embodiments, the air conditioner 10 is formed with a duct 13 located downstream of the air inlet 11. The air conditioner 10 also includes a duct disposed on the air duct Fan 14 and heat exchanger 15 in 13. The fan 14 is used to establish a gas flow, and the heat exchanger 15 is used to exchange heat with the gas stream. The air duct 13 is formed with an air outlet 16 located downstream.

Referring to FIG. 11 and FIG. 14, in the process of adjusting the temperature of the air conditioner 10, the indoor air enters the indoor unit 10a of the air conditioner 10 from the air inlet 11, passes through the heat exchanger 15, and the aluminum foil and the copper tube of the heat exchanger 15 Heat exchange occurs to achieve temperature rise or temperature drop, and the effect of adjusting the indoor temperature is exerted. After passing through the heat exchanger 15, the air passes through the fan 14 in the air duct 13, which is used to drive the airflow through the heat exchanger 15, thereby performing heat exchange to regulate the temperature. When the airflow flows through the fan 14, it is discharged from the air outlet 16, completing the temperature regulation cycle.

In one embodiment, the purification screen 12 is disposed at the air inlet 11 (as shown in Figure 11). More specifically, the purification screen 12 is disposed in front of the air inlet port 11 (determined in the direction of the air flow, and the position where the air current passes first is the front).

When the air conditioner 10 is in operation, the air is driven by the blower 14 to pass through the purification filter 12 before entering the indoor unit 10a of the air conditioner 10, thus realizing the air purifying function.

In another embodiment, the purification screen 12 is disposed between the air inlet 11 and the heat exchanger 15 (as shown in Figures 15 and 16).

When the air conditioner 10 is in operation, the air is driven by the blower 14 to pass through the purification filter 12 before flowing through the heat exchanger 15, thus realizing the air purification function.

Of course, in other embodiments, the purification filter 12 may also be partially disposed at the air inlet 11 and partially disposed between the air inlet 11 and the heat exchanger 15 (as shown in FIG. 17), which is not limited herein.

In some embodiments, the ratio of the orthographic projection of the purification screen 12 at the air inlet 11 to the area of the air inlet 11 is greater than 30%.

It can be understood that when the area of the orthographic projection of the purification screen 12 at the air inlet 11 is larger, the greater the resistance that the air receives when entering the air passage 13, the greater the attenuation of the air volume of the air conditioner 10. In the air conditioner 10 according to the embodiment of the present invention, the ratio of the area between the orthographic projection of the purification screen 12 at the air inlet 11 and the air inlet 11 is only required to be more than 30%, so that the air purification function can be preferably achieved. The wind filter of the purification filter 12 is small, does not cause a large air volume attenuation of the air conditioner 10, and can avoid the influence on the basic performance of the air-conditioning device 10 for cooling and heating.

In some embodiments, the purification screen 12 is in the form of a flat or curved surface.

For example, the purification filter 12 of the air conditioner 10 shown in Fig. 11 has a flat shape, and the purification filter 12 of the air conditioner 10 shown in Fig. 15-17 has a curved shape. It can be understood that when the purifying screen 12 is curved, the ratio of the area of the orthographic projection of the purifying screen 12 at the air inlet 11 to the air inlet 11 should be more than 30%, instead of the actual flat area of the purifying screen 12. The ratio to the area of the air inlet 11 is greater than 30% to calculate.

In one embodiment, the purification screen 12 is parallel to the air inlet 11 when the purification screen 12 is in the form of a flat plate. That is, the surface of the purification screen 12 opposite to the air inlet 11 is parallel to the surface of the air inlet 11 opposite to the purification screen 12. Thus, the air inlet and the exhausting effect are uniform throughout the air inlet 11, and the purification screen 12 is also easy to install. The distance between the purification filter 12 and the air inlet 11 can be determined according to actual conditions to achieve an optimum air purification effect and to minimize the air volume reduction of the air conditioner 10.

Referring to Figures 18-25, in some embodiments, the air inlet 11 is rectangular. The purification screen 12 includes at least one strip-shaped sub-screen that extends straight or obliquely across the air inlet 11 along the length or width of the air inlet 11.

It is to be noted that FIGS. 18-25 are top views of the purification screen 12, that is, an orthographic view of the purification screen 12 at the air inlet 11. At this base The purifying filter 12 may be in the form of a flat plate or a curved surface, and is not limited herein.

It can be understood that the ribbon filter screen is in the form of a belt.

Specifically, FIGS. 18-21 are four embodiments in which the belt-shaped sub-filter extends straight through the air inlet 11 along the length of the air inlet 11. At least one of A1-A3 is a ribbon filter, at least one of A4-A5 is a ribbon filter, at least one of A6-A9 is a ribbon filter, and at least A10-A14 One is a ribbon filter. The distribution position and number of each strip filter are not limited. For example, A2, A5, A6, A8, A11, and A13 may be strip-shaped sub-filters, and A1, A3, A4, A7, A9, A10, A12, and A14 are blank areas.

22-24 show three embodiments in which the belt-shaped sub-filter extends straight across the air inlet 11 in the width direction of the air inlet 11. At least one of B1-B5 is a ribbon filter, at least one of B6-B7 is a ribbon filter, and at least one of B8-B14 is a ribbon filter. The distribution position and number of each strip filter are not limited. For example, B1, B3, B5, B7, B9, B11, and B13 may be strip-shaped sub-filters, and B2, B4, B6, B8, B10, B12, and B14 may be blank areas.

Fig. 25 shows an embodiment in which the belt-shaped sub-filter extends obliquely across the air inlet 11 in the width direction of the air inlet 11. Among them, at least one of C1-C9 is a ribbon-shaped sub-filter. The distribution position and number of the ribbon filter are not limited. For example, C2, C4, C6, and C8 may be strip-shaped sub-filters, and C1, C3, C5, C7, and C9 are blank areas.

For the same reason, the strip filter can extend obliquely across the air inlet 11 along the length of the air inlet 11, which will not be exemplified herein.

In certain embodiments, the ribbon sub-screen comprises a plurality of and spaced apart settings.

For example, in Figure 20-22, A6 and A8 are strip-shaped sub-filters, A6 and A8 are spaced apart; A11 and A13 are strip-shaped sub-filters, A11 and A13 are spaced apart; B1, B3 and B5 are strips. Filter, B1, B3, B5 are set at intervals. The width of the plurality of ribbon sub-filters may be equal or unequal. The distances of the plurality of ribbon sub-screens may be equal or unequal. That is to say, the widths of A6-A14 and B1-B5 may be equal or unequal to each other.

In one embodiment, the plurality of ribbon sub-screens are of equal width. The distance between the plurality of ribbon sub-screens is equal.

In this way, the purification filter 12 is easy to manufacture, the air purification effect is uniform, and the air inlet region is evenly distributed in the air inlet port 11. After the air enters the air channel 13, the heat exchange efficiency with the heat exchanger 15 is high, and there is no heat exchanger 15 The phenomenon of excessive working on the side is advantageous for extending the service life of the air conditioner 10.

It can be understood that even if a plurality of strip-shaped sub-filters are arranged at intervals, a part of the area of the air inlet 11 is not covered by the purifying filter 12, but the position, the area and the number of the air inlets 11 are covered by the reasonable adjustment of the sub-filters, The air purification effect of the air conditioner 10 as a whole can still be achieved. Specifically, the position, the area, the number, and the like of the different strip-shaped sub-filters can be appropriately arranged (for example, each sub-filter is disposed on the wind speed at which the optimal filtering effect can be exerted, while considering the air conditioner 10 The air volume is reduced as small as possible. Thus, the optimal air purification effect is achieved with a minimum area of the purification filter 12, the air volume of the air conditioner 10 is reduced as small as possible, and the cooling and heating performance of the air conditioner 10 is substantially unchanged. .

Referring to FIG. 26, in some embodiments, the ratio of the area between the orthographic projection of the purification screen 12 at the air inlet 11 and the air inlet 11 is 100%.

That is to say, the orthographic projection of the purification screen 12 at the air inlet 11 completely covers the air inlet 11.

It is to be noted that FIG. 26 is a plan view of the purification screen 12, that is, an orthographic view of the purification screen 12 at the air inlet 11. On this basis The purification filter 12 may be in the form of a flat plate or a curved surface, which is not limited herein.

Since the purification filter 12 is used in a large area of the air inlet 11, the air generally needs to pass through the purification filter 12 before entering the heat exchanger 15. The air conditioner 10 has an obvious air purification effect, and can achieve a high CADR (clean air delivery). Rate, clean air amount) value.

Referring to Figures 27-29, in some embodiments, the purification screen 12 is a unitary structure formed with slits. The outer contour of the purification filter 12 cooperates with the air inlet 11.

Thus, the purification filter 12 has an integral structure and is easy to install.

It is to be noted that FIGS. 27-29 are top views of the purification screen 12, that is, an orthographic view of the purification screen 12 at the air inlet 11. On this basis, the purification filter 12 may be in the form of a flat plate or a curved surface, which is not limited herein.

Specifically, the purification filter 12 has an irregular shape as a whole, and the purification filter 12 may be formed with a slit at the edge (D1 in FIG. 27 and D3 in FIG. 29), or a slit is formed in the middle of the purification filter 12 (as shown in the figure). D2) in 28, etc., the shape of the slit may be a triangle, a rectangle, a parallelogram, a circle or an irregular shape. The cooperation of the outer contour of the purification filter 12 with the air inlet 11 may mean that the size and bending curvature of the purification screen 12 cooperate with the structure of the air inlet 11 for installation.

In one embodiment, the plurality of slits are evenly distributed (as shown in Figure 29).

It should be noted that the method for arranging the purification screens 12 of the above embodiments of the present invention may be combined with each other. For example, the purification filter screen 12 may include a plurality of sub-filter screens, some of the sub-filter screens are strip-shaped, and some sub-filter screens are strips. The structure with slits may even have an irregular shape or an arbitrary shape; each sub-screen may be arranged along the length direction of the air inlet 11, or may be arranged along the width direction of the air inlet 11; the purification screen 12 may completely cover the air inlet 11 It is also possible to partially cover the air inlet 11 so as to satisfy the ratio of the area between the orthographic projection of the purification screen 12 at the air inlet 11 and the air inlet 11 of more than 30%.

Referring again to FIG. 11, in some embodiments, the air conditioner 10 further includes an ionizer 17 disposed within the air duct 13. The ionizer 17 is used to generate positive ions and/or negative ions.

Specifically, the ionizer 17 uses a high voltage transformer to boost the power frequency voltage to a desired voltage to generate ions and release the ions into the surrounding environment to purify the air.

The ionizer 17 can be a negative ion generator, or a positive ion generator, or a positive and negative ion generator. It can be understood that a negative ion generator is used to generate negative ions, a positive ion generator is used to generate positive ions, and a positive and negative ion generator is used to generate positive ions and negative ions. The type of ion generator 17 can be selected according to actual conditions.

The ion generator 17 generates positive ions and/or negative ions, which on the one hand can kill bacteria in the air, and on the other hand can charge dust or particles in the air, thereby being more easily adsorbed on the purification screen 12. In addition, after the dust or particles in the air are charged, even through the purification filter 12 whose filter aperture is much larger than its own size (especially through the oppositely charged purification filter 12), it is adsorbed with very high efficiency. Thus, the filter pore size of the purification filter 12 can be much larger than the diameter of the dust or particles, thereby substantially lowering the passage of the purification filter 12. The wind resistance is ensured that the cooling and heating performance and the air volume of the air conditioner 10 itself are substantially unaffected.

When the actual air mass is greater than the set air quality and the operating voltage of the ionizer 17 is raised, the ion generator 17 will generate more positive ions and/or negative ions per unit time, and on the one hand, can accelerate the killing of bacteria in the air. On the other hand, more dust or particles in the air are charged and are more easily adsorbed on the purification screen 12. When the wind speed of the fan 14 is raised, on the one hand, the charged dust or particles can be accelerated to the purification filter 12; on the other hand, the rate at which the air passes through the purification filter 12 can be increased, so that more air is consumed per unit time. The purification filter 12 is cleaned to speed up the air purification rate.

When the actual air mass is less than the set air quality and the operating voltage of the ionizer 17 is lowered, on the one hand, the increase of ozone in the indoor air due to the generation of a large amount of ions by the ion generator 17 can be reduced; on the other hand, the air can be avoided. The presence of a large amount of ions causes the non-contaminating particles to be charged, thereby adsorbing onto the purification filter 12, affecting the service life of the purification filter 12.

In one embodiment, the ionizer 17 can be used with the purification screen 12. For example, when the ionizer 17 is a negative ion generator, the purification screen 12 can be a positively charged purification screen 12. Thus, the ionizer 17 generates negative ions, so that dust or particles in the air are negatively charged, thereby being more easily adsorbed on the positively charged purification filter 12, thereby increasing the CADR value.

In some embodiments, the ionizer 17 is disposed at the air outlet 16.

As such, the ionizer 17 kills germs in the air and purifies the air by generating positive ions and/or negative ions.

Of course, in other embodiments, the ionizer 17 may be disposed at other locations of the indoor unit 10a of the air conditioner 10 to achieve the effects of killing germs and purifying the air.

In one embodiment, electrostatic electret filter 122 or active electrostatic precipitator screen 124 can be used in conjunction with ionizer 17.

It can be understood that when the ion generator 17 is disposed in the air duct 13, the ion generator 17 diverges positive ions and/or negative ions into the air, so that the dust or particles are charged, and the charged dust or particles will be more easily adsorbed in the electrostatic electret filter. On the net 122 or the active electrostatic dust filter 124, the air purifying function of the purifying filter 12 is further improved, and at the same time, the use intensity of the electrostatic electret material and the dust collecting electrode is reduced, thereby reducing the wind resistance of the purifying filter 12. .
