Referring to FIGS. 1 , 2 and 6 , the air conditioner 10 according to the embodiment of the present invention is formed with an air inlet 11 . The air conditioner 10 also includes a purification screen 12 for purifying air. The purification screen 12 includes a plurality of screen areas 121 of at least two different thicknesses for filtering out at least two different contaminants.

The air conditioner 10 of the embodiment of the present invention is provided with a purifying screen 12 for purifying air, and the purifying screen 12 includes a plurality of screen areas 121 of at least two different thicknesses for filtering out at least two different contaminants, In this way, the air conditioner 10 can not only adjust the indoor temperature, but also effectively filter out various pollutants in the air, and ensure that the cooling and heating performance is substantially unchanged.

It can be understood that various pollutants such as solid pollutants and gaseous pollutants exist in the air. Solid contaminants include PM2.5, PM10, pollen, bacteria, dander and the like. Gaseous pollutants include formaldehyde, benzene, odor, and the like. In this way, part of the filter area 121 may adopt a filter type or an electrostatic type filter to filter out solid contaminants; some of the filter area 121 may adopt an adsorption type or a catalytic type filter to filter out gaseous pollutants. It can be understood that the parameters such as the shape, wind resistance and filtration characteristics of the filter for filtering out solid pollutants and filtering out gaseous pollutants are different. The purification filter screen 12 of the embodiment of the present invention includes at least two filter screen regions 121 of different thicknesses for filtering out at least two different pollutants to simultaneously filter out at least two kinds of pollutions of solid pollutants and gaseous pollutants. The air purifying effect of the air conditioner 10 can be enhanced.

Of course, the types of contaminants used by the screen area 121 for filtering are not limited to solid contaminants and gaseous contaminants. Part of the screen area 121 can also be configured to filter out other types of contaminants in the air.

In some embodiments, the air conditioner 10 is formed with a duct 13 located downstream of the air inlet 11. The air conditioner 10 further includes a fan 14 and a heat exchanger 15 disposed in the air duct 13. The fan 14 is used to establish a gas flow, and the heat exchanger 15 is used to achieve heat exchange of the gas flow for temperature regulation purposes. The air duct 13 is formed with an air outlet 16 located downstream.

During the temperature adjustment of the air conditioner 10, the indoor air enters the indoor unit 10a of the air conditioner 10 through the air inlet 11, passes through the heat exchanger 15, exchanges heat with the aluminum foil and the copper tube of the heat exchanger 15, thereby achieving temperature rise or Cool down and play the role of regulating the indoor temperature. After passing through the heat exchanger 15, the air passes through the fan 14 in the air duct 13, and the fan 14 is used to drive The moving gas flows through the heat exchanger 15 to cause heat exchange. When the airflow flows through the fan 14, it is discharged from the air outlet 16, completing a temperature adjustment cycle. During this cycle, the temperature of the airflow is detected by the temperature sensing probe 18 disposed in the air duct 13 before the heat exchanger 15, and the current temperature of the air conditioner 10 determines whether the current air temperature reaches the set temperature, and calculates the current airflow. The difference between the temperature and the set temperature. The single-chip microcomputer of the air conditioner 10 sends a corresponding driving signal to drive the compressor and the fan 14 according to the difference, so that the actual temperature in the room is constantly approaching the indoor ideal temperature set by the user (ie, the set temperature).

In some embodiments, the purification screen 12 is disposed adjacent to the air inlet 11.

In one embodiment, the purification screen 12 is disposed at the air inlet 11 (as shown in Figure 1). 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 3 and 4). 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 , partially disposed between the air inlet 11 and the heat exchanger 15 (as shown in FIG. 5 ), and the purification filter 12 may also be disposed. Any position where the air flows in the indoor unit 10a 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. Thus, the wind resistance is reduced, and the air volume attenuation of the air conditioner 10 due to the purification filter 12 is reduced, thereby avoiding the influence on the basic performance of the cooling and heating of the air conditioner 10.

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. 1 has a flat shape, and the purification filter 12 of the air conditioner 10 shown in Figs. 3-5 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. Purification filter 12 and air intake The distance between the ports 11 can be determined according to actual conditions to achieve an optimum air purification effect and to reduce the air volume of the air conditioner 10 as small as possible.

In certain embodiments, the purification screen 12 includes a plurality of sub-screens correspondingly disposed in the plurality of screen areas 121.

It can be understood that the plurality of filter areas 121 are at least two filter areas 121. For example, in FIG. 6, the number of filter areas 123 may be three, and the corresponding sub-filters are A1, A2, and A3. Wherein, A1, A2, and A3 include at least two different thicknesses, and the thickness relationship may be A1=A2≠A3, or A1≠A2≠A3, or A1≠A2=A3, or A2≠A1=A3, which is not limited herein. A1, A2, and A3 are used to filter out at least two kinds of contaminants, that is, A1, A2, and A3 include at least two different kinds of filters, which may be the same type of A1 and A2, but different from A3; or A1 and A3 are of the same type, but different from A2; or A2 and A3 are the same, but different from A2; or A1, A2, and A3 are different, and are not limited herein.

Referring to Figures 6-13, in some embodiments, the air inlet 11 is rectangular. Multiple sub-filters are strip-shaped. The plurality of sub-filters extend straight or obliquely across the air inlet 11 along the length or width direction of the air inlet 11.

It should be noted that FIGS. 6-13 are top views of the purification screen 12, ie, an orthographic view of the purification screen 12. 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, FIGS. 6-9 are four embodiments in which a plurality of sub-filters extend straight across the air inlet 11 along the length of the air inlet 11. Among them, there are at least two sub-filters of different thickness in A1-A3, A4-A5 are two sub-filters of different thickness, and at least two sub-filters of different thickness in A6-A9, at least in A10-A14 There are two sub-screens of different thicknesses. There are at least two different kinds of sub-filters in A1-A3, A4-A5 are two different kinds of sub-filters, at least two different kinds of sub-filters in A6-A9, and at least two of A10-A14 Different kinds of sub-filters. The distribution position, the specific number, the specific thickness and the specific type of each sub-filter are not limited. For example, A1, A3, A4, A5, A6, A8, A11, A13, and A14 may be sub-filters, and A2, A7, A9, A10, and A12 are blank areas. The thickness relationship may be A1≠A3, A4≠A5, A6≠A8, A11≠A13=A14. The type relationship may be different for A1 and A3, A4 and A5 are different, A6 and A8 are different, and A11, A13, and A14 are different.

10-12 show three embodiments in which a plurality of sub-filters extend straight across the air inlet 11 in the width direction of the air inlet 11. Among them, B1-B5 has at least two sub-filters of different thicknesses, B6-B7 are two sub-filters of different thickness, and B8-B14 has at least two sub-screens of different thickness. There are at least two different kinds of sub-filters in B1-B5, B6-B7 are two different kinds of sub-filters, and at least two different kinds of sub-filters in B8-B14. The distribution position, the specific number, the specific thickness and the specific type of each sub-filter are not limited. For example, B1, B3, B5, B6, B7, B9, B11, and B13 may be sub-filters, and B2, B4, B8, B10, B12, and B14 may be blank areas. The thickness relationship may be B1 ≠ B3 ≠ B5, B6 ≠ B7, B9 ≠ B11 = B13. The type relationship may be the same for B1 and B3, and different from B5; B6 and B7 are different, B11 and B13 are the same, and B9 is different.

Fig. 13 shows an embodiment in which a plurality of sub-filters extend obliquely across the air inlet 11 in the width direction of the air inlet 11. Among them, C1-C9 There are at least two sub-filters of different thicknesses. There are at least two different kinds of sub-filters in C1-C9. The distribution position, the specific number, the specific thickness and the specific type of each sub-filter are not limited. For example, C2, C4, C6, and C8 may be sub-filters, and C1, C3, C5, and C7 may be blank areas. The thickness relationship may be C2 ≠ C4 = C6 ≠ C8. The type relationship may be the same for C4 and C6, but different from C2 and C8.

Similarly, a plurality of sub-filters may extend across the air inlet 11 along the length of the air inlet 11, which will not be exemplified herein.

In some embodiments, a plurality of sub-screens are spaced apart.

It can be understood that when the air inlet 11 is rectangular or not rectangular, and the sub-filter is in the form of a strip or a strip, the plurality of sub-filters can be spaced apart.

For example, in FIG. 8-10, when the orthographic projection of the purification filter 12 is rectangular, the air inlet 11 has a rectangular shape, the sub-filter has a strip shape, A6 and A8 are sub-filters, and A6 and A8 are spaced apart; A13 is a sub-filter, A11 and A13 are spaced apart; B1, B3, and B5 are sub-filters, and B1, B3, and B5 are spaced apart. The widths of the plurality of sub-filters may be equal or unequal. The distances of the plurality of sub-screens may be equal or unequal.

For example, in FIGS. 14-15, when the orthographic projection of the purification filter 12 is elliptical, D1, D2, and D3 are sub-filters, and D1, D2, and D3 are spaced apart; and D4, D5, and D6 are sub-filters. D4, D5, D6 interval settings. The widths of the plurality of sub-filters may be equal or unequal. The distances of the plurality of sub-screens may be equal or unequal.

For example, in FIG. 16-18, when the orthographic projection of the purification filter 12 is of any shape, E1, E2, and E3 are sub-filters, and E1, E2, and E3 are spaced apart; and E4, E5, and E6 are sub-filters. E4, E5, and E6 are set at intervals; E7, E8, and E9 are sub-filters, and E7, E8, and E9 are set at intervals. The shapes of the plurality of sub-filters may be the same or different. The shape of the plurality of sub-filters may be a triangle, a square, a parallelogram, a circle, a polygon, or an arbitrary shape.

Of course, in other embodiments, multiple sub-filters may also be disposed at incomplete intervals. For example, in FIG. 19, when the orthographic projection of the purification screen 12 is elliptical, F1, F2, and F3 are sub-filters, and F1 and F2 are spaced apart, and F2 and F3 are connected together.

In one embodiment, when a plurality of sub-screens are spaced apart, the plurality of sub-screens have the same width. Multiple sub-filters are equally spaced apart.

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 sub-screens are arranged at intervals, a part of the area of the air inlet 11 is not covered by the purification filter 12, but the position, area and the number of blocks of the air inlet 11 are covered by appropriately setting different thicknesses and different kinds of sub-filters. The air purification effect of the air conditioner 10 as a whole can still be better. Specifically, different types of sub-filters have different parameters such as air flow rate and filter thickness for optimal filtration. When the filter is set, for example, different types and thicknesses of sub-filters can be set according to the characteristics of different types of sub-filters, depending on the air flow rate at the position of the sub-filter. The filter screen can also adjust the area and the number of different types of sub-filters according to the actual situation of air pollutants at the installation position of the air conditioner 10, so as to achieve an optimal air purification effect and air volume to the air conditioner 10. The reduction is as small as possible and the cooling and heating performance of the air conditioner 10 is substantially unchanged.

Referring to Figures 20-22, in some embodiments, the outer contours of the plurality of sub-screens cooperate with the air inlets 11.

As such, the purification filter 12 is easy to install.

It should be noted that FIGS. 20-22 are top views of the purification screen 12, ie, an orthographic view of the purification screen 12. 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, each sub-filter may have a regular or irregular shape. For example, the shape of the sub-filter may be a triangle, a square, a parallelogram, a circle or a polygon, or the like. 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. There may be gaps or slits between the individual filter screens, or the individual filter screens may be partially or completely spliced together.

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 100%.

That is to say, the orthographic projection of the purification screen 12 at the air inlet 11 completely covers the air inlet 11. For example, in Fig. 9, when the orthographic projection of the purification screen 12 is a rectangle, A10-A14 are all sub-screens, and there is no blank area. For example, in Fig. 23, when the orthographic projection of the purification screen 12 is elliptical, all of G1-G3 are sub-filters, and there is no blank area. For example, in Fig. 24, when the orthographic projection of the purification screen 12 is of an arbitrary shape, all of H1-H4 are sub-filters, and there is no blank area.

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 Figure 25, in some embodiments, the purification screen 12 comprises multiple layers. The multi-layer purification filter 12 is spaced apart.

Specifically, in one example, the purification screen 12 includes a first layer of purification screen 12a and a second layer of purification screen 12b. The first purification filter screen 12a is disposed in front of the air inlet port 11, and the second layer purification filter screen 12b is disposed between the air inlet port 11 and the heat exchanger 15. Of course, the first purification filter 12a and the second purification filter 12b may also be disposed between the air inlet 11 and the heat exchanger 15, or may be disposed at any position where the air flows in the indoor unit 10a.

It should be noted that the method for arranging the purification filter 12 of the above embodiments of the present invention may be combined with each other. For example, the purification filter 12 may include a plurality of sub-filters, and the plurality of sub-filters may be combined with different thicknesses and different types; The partial sub-filter may be in the form of a strip, and the partial sub-screen may be a structure with a slit, or may be an irregular shape or an arbitrary shape; each sub-filter may be arranged along the length of the air inlet 11 or along the air inlet. 11 is arranged in the width direction; each sub-filter can be arranged at intervals; the purifying filter 12 can cover the air inlet 11 or partially cover the air inlet 11; the purifying filter 12 can also be a multi-layer combination to strengthen the air conditioner 10. The air purification effect effectively filters out various pollutants in the air.

Referring again to FIG. 1, in some embodiments, the air conditioner 10 further includes ion generation disposed in the air duct 13. 17. 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 them 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 aperture of the purification filter 12 can be much larger than the diameter of the dust or particles, thereby substantially lowering the passage wind resistance of the purification filter 12, ensuring that the refrigeration and heating performance and the air volume of the air conditioner 10 itself are substantially unaffected.

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.
