[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0042] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0043] The air conditioner 1000 of this utility model is described below with reference to the accompanying drawings.

[0044] According to an embodiment of the present utility model, the air conditioner 1000, such as Figure 1 and Figure 2 As shown, the air conditioner 1000 includes: an air duct component 10 and a purification component 20. The air duct component 10 defines a purification air duct 11. The purification component 20 includes a charge grid assembly 3 and an electrostatic dust collection assembly 4 disposed within the purification air duct 11. The charge grid assembly 3 is disposed upstream of the electrostatic dust collection assembly 4 along the airflow direction of the purification air duct 11. Figure 3 As shown, the charged grid assembly 3 includes a plurality of charged units 31 arranged sequentially along the airflow direction W. Each charged unit 31 includes a first electrode 311 and a second electrode 312. The side of the first electrode 311 facing the second electrode 312 has a discharge tip 3111.

[0045] Airflow flows along the purification duct 11. The purification component 20, installed within the purification duct 11, purifies the airflow, improving the cleanliness of the air outlet of the air conditioner 1000 and thus enhancing indoor air quality. The purification component 20 includes a charged grid assembly 3 and an electrostatic dust collection assembly 4. When the charged unit 31 of the charged grid assembly 3 is energized, the discharge tip 3111 formed on the first electrode 311 releases negative ions. When airborne particles pass through, they are adsorbed by the negative ions and thus acquire a negative charge.

[0046] The electrostatic dust collection component 4 is located upstream of the charged grid component 3. Charged particles will be adsorbed onto the electrostatic dust collection component 4 as they pass through it. The electrostatic dust collection component 4 filters and purifies the airflow, thereby reducing dust particles in the airflow within the purification duct 11 and improving the air quality of the air conditioner 1000.

[0047] The electrostatic precipitator assembly 3 includes multiple charged units 31 arranged sequentially along the airflow direction W. By setting multiple charged units 31, the concentration of negative ions in the assembly is increased. Furthermore, since the airflow passing through the assembly passes through multiple charged units 31 sequentially, even if particles in the airflow avoid the adsorption of negative ions at the upstream charged unit 31, they will be adsorbed by negative ions at the downstream charged unit 31. This increases the probability of particles in the airflow being adsorbed and carrying negative ions, improving the situation where negative ions are not adsorbed due to excessive airflow velocity. This enhances the purification effect of the electrostatic precipitator assembly 4 on the flowing airflow and improves the purification effect of the purification component 20. It also allows particles to adsorb more negative ions per unit time; the adsorption efficiency is even higher when charged particles pass through the electrostatic precipitator assembly 4, thereby improving the purification and dust removal effect.

[0048] It is worth noting that the voltage of multiple charged units 31 can be set individually. The voltage of the discharge tip 3111 of the first electrode 311 of different charged units 31 can be different. Of course, the voltage of the discharge tip 3111 of the first electrode 311 of different charged units 31 can also be the same. Gnu can flexibly control the voltage according to actual needs, thereby meeting diverse requirements.

[0049] According to the embodiment of the present invention, the air conditioner 1000, by arranging a plurality of charged units 31 in sequence along the airflow direction W, can not only increase the concentration of negative ions in the charged components, but also increase the probability that particulate matter in the airflow will be adsorbed by negative ions and carry negative ions as the airflow passes through the plurality of charged units 31 in sequence, and can also enable particulate matter to adsorb more negative ions per unit time, thereby improving the purification effect of the purification component 20.

[0050] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, at least one charged unit 31 is a first charged unit 31a. The first electrode 311 and the second electrode 312 in the first charged unit 31a are arranged in the first direction X1, which is perpendicular to the airflow direction W. In short, the first electrode 311 and the second electrode 312 in the first charged unit 31a are arranged sequentially along the direction perpendicular to the airflow direction W.

[0051] The charged component includes multiple charged units 31 arranged along the airflow direction W, wherein at least one charged unit 31 is a first charged unit 31a. The first electrode 311 and the second electrode 312 in the first charged unit 31a are arranged perpendicular to the airflow direction W. In the direction perpendicular to the airflow direction W, the negative ions released by the discharge tip 3111 of the first electrode 311 have a larger coverage area, and the negative ions are more likely to adsorb the particulate matter in the airflow, which can improve the purification effect of the purification component 20.

[0052] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the first charging unit 31a includes a plurality of sub-units a spaced apart along the first direction X1. Each sub-unit a includes a first electrode 311 and a second electrode 312. The second electrode 312 extends along the second direction X2. The first electrode 311 includes a plurality of discharge tips 3111 spaced apart along the second direction X2. The second direction X2 is perpendicular to the first direction X1 and the airflow direction W, respectively. This can increase the concentration of negative ions in the charging component and increase the probability that particulate matter in the airflow is adsorbed by negative ions and carries negative ions, thereby improving the purification effect of the purification component 20.

[0053] In some embodiments of the present invention, Figure 4 As shown, the first charge unit 31a includes multiple sub-units a, each sub-unit a including a first electrode 311 and a second electrode 312. The multiple sub-units a are arranged in a gap array, which can improve the regularity of the arrangement, reduce the assembly difficulty, and improve the assembly efficiency.

[0054] The arrangement direction of the first electrode 311 and the second electrode 312 in subunit a can be selected according to actual needs.

[0055] In one embodiment of this utility model, such as Figure 4 As shown, multiple sub-units a are evenly spaced in the first direction X. The number of sub-units a is even. The discharge tips 3111 of half of the sub-units a on the left side of the central plane in the first direction X face to the right, and the discharge tips 3111 of half of the sub-units a on the right side of the central plane face to the left. This ensures that the ventilation area is adequately covered with negative ions, thereby improving the purification effect of the charged grid component 3.

[0056] In some embodiments of the present invention, Figure 5 As shown, in the first direction X, multiple sub-units a are evenly spaced. The number of sub-units a is even. Two adjacent sub-units a are grouped together and arranged back to back. This is so that the discharge tip 3111 of the left sub-unit a in the group faces to the left and the discharge tip 3111 of the right sub-unit a faces to the right. This ensures that negative ions are distributed sufficiently in the area through which the airflow passes, thereby improving the purification effect of the charged grid component 3.

[0057] In some embodiments of the present invention, Figure 3 and Figure 6As shown, at least one charging unit 31 is a longitudinally arranged charging unit 31d; wherein, at least one longitudinally arranged charging unit 31d is a second charging unit 31b, and the first electrode 311 in the second charging unit 31b is located downstream of the second electrode 312, so that the discharge tip 3111 of the first electrode 311 of the second charging unit 31b extends toward the inlet side 3m of the charging grid assembly.

[0058] The charged assembly includes multiple charged units 31 arranged along the airflow direction W, wherein at least one charged unit 31 is a longitudinally arranged charged unit 31d. The first electrode 311 and the second electrode 312 in the longitudinally arranged charged unit 31d are located upstream and downstream of the purification air duct 11, respectively. It can be understood that the first electrode 311 and the second electrode 312 can be arranged sequentially along the airflow direction W, or they can be arranged in a direction with an offset angle from the airflow direction W.

[0059] The second charging unit 31b is a longitudinally arranged charging unit 31d. The first electrode 311 in the second charging unit 31b is located downstream, and the second electrode 312 is located upstream. The discharge tip 3111 of the first electrode 311 extends toward the inlet side 3m of the charging grid assembly, and the airflow flows through the second electrode 312 and the first electrode 311 in sequence.

[0060] In some embodiments of this utility model, such as Figure 3 and Figure 6 As shown, at least one charging unit 31 is a vertically arranged charging unit 31d; wherein, at least one vertically arranged charging unit 31d is a third charging unit 31c, and the first electrode 311 in the third charging unit 31c is located upstream of the second electrode 312, so that the discharge tip 3111 of the first electrode 311 of the third charging unit 31c extends toward the outlet side 3n of the charging grid assembly.

[0061] The charged grid assembly 3 includes multiple charged units 31 arranged along the airflow direction W, wherein at least one charged unit 31 is a longitudinally arranged charged unit 31d. The first electrode 311 and the second electrode 312 in the longitudinally arranged charged unit 31d are located upstream and downstream of the purification air duct 11, respectively. It can be understood that the first electrode 311 and the second electrode 312 can be arranged sequentially along the airflow direction W, or they can be arranged in a direction with an offset angle from the airflow direction W.

[0062] The third charging unit 31c is a vertically arranged charging unit 31d. The first electrode 311 in the third charging unit 31c is located upstream, and the second electrode 312 is located downstream. The discharge tip 3111 of the first electrode 311 extends toward the outlet side 3n of the charging grid assembly, and the airflow flows through the first electrode 311 and the second electrode 312 in sequence.

[0063] In some embodiments of this utility model, such as Figure 3 and Figure 6 As shown, the charged grid assembly 3 includes a second charged unit 31b and a third charged unit 31c, with the second charged unit 31b located upstream of the third charged unit 31c.

[0064] The charged grid assembly 3 includes multiple charged units 31 arranged along the airflow direction W. Among the multiple charged units 31, there is at least one second charged unit 31b and one third charged unit 31c. The second charged unit 31b is located near the inlet side 3m of the charged grid assembly, and the third charged unit 31c is located near the outlet side 3n of the charged grid assembly. The airflow first passes through the second charged unit 31b and then through the third charged unit 31c.

[0065] In some embodiments of the present invention, Figure 3 As shown, the distance B between the first electrode 311 in the second charging unit 31b and the first electrode 311 in the third charging unit 31c is greater than or equal to 5 mm.

[0066] The second charge unit is located upstream of the third charge unit 31c. The first electrode 311 in the second charge unit 31b is close to the inlet side 3m of the charge grid assembly, and the first electrode 311 in the third charge unit 31c is close to the outlet side 3n of the charge grid assembly. The first electrode 311 in the second charge unit 31b and the first electrode 311 in the third charge unit 31c are adjacent. Therefore, limiting the distance B between the first electrode 311 in the second charge unit 31b and the first electrode 311 in the third charge unit 31c to greater than or equal to 5mm can reduce the probability of short circuit and improve the working reliability of the charge grid assembly 3.

[0067] In some embodiments of the present invention, Figure 6 As shown, the charged grid assembly 3 includes a plurality of longitudinally arranged charged units 31d; wherein, the discharge tips 3111 of the first electrodes 311 of at least two adjacent longitudinally arranged charged units 31d are aligned.

[0068] The charged assembly includes multiple charged units 31 arranged along the airflow direction W, and multiple vertically arranged charged units 31d. The discharge tips 3111 of the first electrodes of at least two adjacent vertically arranged charged units 31d are aligned, which can improve the regularity of the arrangement, reduce the assembly difficulty, and improve the assembly efficiency.

[0069] In some embodiments of the present invention, Figure 7 As shown, the charge grid assembly 3 includes a plurality of longitudinally arranged charge units 31d; wherein, the discharge tips 3111 of the first electrodes 311 of at least two adjacent longitudinally arranged charge units 31d are staggered.

[0070] The charged assembly includes multiple charged units 31 arranged along the airflow direction W, and includes multiple vertically arranged charged units 31d. The airflow passes through the multiple vertically arranged charged units 31d sequentially. The discharge tips 3111 of the first electrodes 311 of two adjacent vertically arranged charged units 31d are staggered. In the airflow direction, the gap of the upstream first electrode 311 is opposite to the discharge tip 3111 of the downstream first electrode 311, and similarly, the gap of the downstream first electrode 311 is opposite to the discharge tip 3111 of the upstream first electrode 311.

[0071] Even if particulate matter in the airflow avoids the adsorption of negative ions at the upstream longitudinally charged unit 31d, it will be adsorbed by negative ions at the downstream longitudinally charged unit 31d. This increases the probability that particulate matter in the airflow will be adsorbed by negative ions and carry negative ions. It can improve the situation where negative ions are not adsorbed by particulate matter due to excessive airflow velocity, thereby improving the purification effect of electrostatic dust collection component 4 on the airflow and improving the purification effect of purification component 20.

[0072] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the load grid assembly 3 includes a frame 32 and a support unit 33. The frame 32 defines a frame opening 321 that extends through the airflow direction W. The support unit 33 includes a plurality of support bars 331 that extend along the third direction Y and are spaced apart along the fourth direction Z. The third direction Y is perpendicular to the fourth direction Z and is also perpendicular to the airflow direction W.

[0073] like Figure 8 and Figure 9 As shown, a single longitudinal charging unit 31d is provided corresponding to a single support unit 33, and a single longitudinal charging unit 31d includes a plurality of first electrodes 311 provided in a one-to-one correspondence with a plurality of support bars 331. Each first electrode 311 includes a plurality of discharge tips 3111 provided at intervals along the length direction of the support bar 331.

[0074] The frame 32 and the support unit 33 provide support. The frame 32 defines a frame opening 321 located on the outer periphery of the charged unit 31. The support unit 33 is installed inside the frame 32 and is used to support the installation of the charged unit 31. The support unit 33 includes multiple support bars 331, which are installed inside the frame 32. The support bars 331 are arranged perpendicular to the opening direction of the frame opening 321, and extend along the third direction Y and are spaced apart along the fourth direction Z.

[0075] Each vertically arranged charged unit 31d is correspondingly arranged with a single support unit 33. The support unit 33 includes multiple support bars 331 spaced apart along the fourth direction Z. The vertically arranged charged unit 31d includes multiple first electrodes 311 spaced apart along the fourth direction Z. The first electrodes 311 are correspondingly arranged on the support bars 331, which can improve the regularity of the arrangement.

[0076] Each first electrode 311 includes multiple discharge tips 3111 spaced apart along the third direction Y. By setting multiple discharge tips 3111, the concentration of negative ions in the charged component can be increased, enabling particles to adsorb more negative ions per unit time. When charged particles pass through the electrostatic dust collection component 4, the adsorption efficiency is higher, thereby improving the purification and dust removal effect.

[0077] In some embodiments of this utility model, such as Figure 8 As shown, a first electrode 311 includes a plurality of discharge needles spaced apart along a third direction Y, the discharge needles forming discharge tips 3111, and the plurality of discharge needles in a first electrode 311 are connected to a wire.

[0078] In other embodiments of this utility model, such as Figure 9 As shown, a first electrode 311 includes a discharge steel plate extending in the third direction Y, and a discharge tip 3111 protruding toward the second electrode 312 is formed on the discharge steel plate.

[0079] In some embodiments of this utility model, such as Figure 10 As shown, a single longitudinally arranged charged unit 31d includes a second electrode 312. The second electrode 312 is in the form of a perforated plate with multiple perforations 3121 and is arranged perpendicular to the airflow direction W. A discharge tip 3111 is respectively arranged at the center of each perforation 3121.

[0080] By setting the second electrode 312 in the form of an orifice plate, one second electrode 312 can correspond to multiple first electrodes 311 spaced apart along the fourth direction Z, which can reduce the assembly difficulty. In addition, the orifice plate form can also reduce the air resistance in the purification air duct 11 and improve the airflow.

[0081] In some embodiments of this utility model, such as Figure 11 and Figure 12 As shown, the air conditioner 1000 includes a fresh air module 100 and a heat exchange module 200. The fresh air module 100 includes a fresh air fan 50, an air duct component 10, and a purification component 20. The fresh air fan 50 is located below the air duct component 10 and supplies air to the purification air duct 11. The purification component 20 is removably mounted on the air duct component 10. The air duct component 10 includes power supply contacts that are electrically connected to the purification component 20. The heat exchange module 200 is located above the fresh air module 100 and includes a heat exchanger 201 and a fan 202.

[0082] The fresh air module 100 includes a fresh air fan 50, an air duct component 10, and a purification component 20. Airflow flows along the purification air duct 11. The purification component 20 is installed in the purification air duct 11 and can purify the airflow. The fresh air fan 50 generates airflow and is located below the air duct component 10 and supplies air to the purification air duct 11.

[0083] The air duct component 10 includes a power supply contact that is electrically connected to the purification component 20. When excessive dust accumulates on the purification component 20, it can be removed from the air duct component 10, separating it from the power supply contact. The purification component 20 is then de-energized, allowing for cleaning to remove dust. After cleaning, the purification component 20 can be reinstalled into the air duct component 10, reconnecting to the power supply contact and enabling normal operation. The power supply contact design enhances safety during use.

[0084] The air conditioner 1000 also includes a heat exchange module 200, which can exchange heat with the airflow passing through it, thereby regulating the indoor temperature. The heat exchange module 200 is located above the fresh air module 100. The airflow purified by the fresh air module 100 then flows through the heat exchange module 200, thereby delivering clean fresh air at a suitable temperature to the room, regulating the indoor temperature and the indoor air quality.

[0085] Hereinafter, a fresh air module 100 according to a specific embodiment of the present application will be described with reference to the accompanying drawings.

[0086] The electrostatic dust collection component 4 and the grid charging component 3 share a high-voltage transformer for power supply. The grid charging component 3 has elastic conductive sheets, with a microswitch positioned between two of these sheets. The electrostatic dust collection component 4 has conductive contacts at corresponding positions on the elastic conductive sheets. After the electrostatic dust collection component 4 is installed into the air duct component 10, its lower support and conductive contacts simultaneously contact the elastic conductive sheets and microswitch on the grid charging component 3. At this time, the high-voltage transformer supplies power to both the electrostatic dust collection component 4 and the grid charging component 3. When the electrostatic dust collection component 4 is removed for cleaning, the microswitch automatically resets and opens, the high-voltage transformer stops operating, and power is cut off to both the grid charging component 3 and the electrostatic dust collection component 4, preventing electric shock accidents if the user touches the fresh air module 100.

[0087] During normal operation, the charged grid component 3 releases negative ions through the discharge tip 3111. When airborne particles pass by, they are adsorbed by the negative ions and become negatively charged. Then, when the charged particles pass by the electrostatic dust collection component 4, they are adsorbed onto the positive electrode of the electrostatic dust collection component 4. After working for a period of time, the electrostatic dust collection component 4 can be extracted and washed with water for reuse.

[0088] The charged grid assembly 3 includes a second charged unit 31b and a third charged unit 31c. The second charged unit 31b is located upstream of the third charged unit 31c. In the following text, "up" and "down" refer to the upstream and downstream directions of the airflow.

[0089] The first electrode 311 is constructed as a unidirectional stainless steel needle, and the second electrode 312 is constructed as a stainless steel electrode plate. The stainless steel electrode plates are respectively installed on both sides of the opening direction of the frame 321 of the frame 32. The two stainless steel electrode plates can be designed in a four-square grid, six-square grid, nine-square grid, etc. The second electrode 312 has a hollow design in the middle.

[0090] The frame 32 is provided with two support units 33 spaced apart along the airflow direction W. Each support unit 33 includes three support bars 331 extending along the third direction Y. The support bars 331 are provided with glue-filling grooves. The glue-filling grooves on the two support units 33 are designed back to back. The unidirectional stainless steel needle is installed in the mounting hole of the glue-filling groove. After installation, the unidirectional stainless steel needle is located in the center of the stainless steel electrode sheet (a unidirectional stainless steel needle is provided in the center of each hollowed-out stainless steel electrode sheet). After installation, the unidirectional stainless steel needle is fixedly installed on the support bar by glue filling.

[0091] The unidirectional stainless steel needle is installed in the center of the hollowed-out stainless steel electrode sheet. The vertical distance between the unidirectional stainless steel needle and the stainless steel electrode sheet should be controlled within 3-8mm (and the needle tip should be lower than the stainless steel electrode sheet). In order to extend the time that the particles pass through the load grid assembly 3, the distance between the upper and lower glue tanks should be controlled at more than 5mm.

[0092] The lower stainless steel electrode plate and the downward-facing unidirectional stainless steel needle form a discharge module. When energized, the discharge tip 3111 releases negative ions. The upper stainless steel electrode plate and the upward-facing stainless steel needle form a discharge module. When energized, the discharge tip 3111 releases negative ions. Therefore, when particulate matter in the air passes through the charged grid component 3, it can adsorb the negative ions released by this module twice, thereby allowing the particulate matter to adsorb more negative ions per unit time. Consequently, when charged particulate matter passes through the electrostatic dust collection component 4, the adsorption efficiency is higher, thus improving the purification and dust removal effect.

[0093] The load grid assembly 3 also includes an upper protective mesh cover 34 and a lower protective mesh cover 34. The upper protective mesh cover 34, the upper stainless steel electrode plate and the frame 32 are fixedly connected by a series of three screws. The lower protective mesh cover 34, the lower stainless steel electrode plate and the frame 32 are fixedly connected by a series of three screws.

[0094] The following describes a comparison of experimental data on the negative ion concentration of the charged grid component in Example 1 and the charged grid component in Comparative Example 1.

[0095] The charge grid assembly 3 of Embodiment 1 is characterized as follows: the charge grid assembly 3 includes a second charge unit 31b and a third charge unit 31c. The second charge unit 31b is located upstream of the third charge unit 31c. The first electrode 311 is constructed as a unidirectional stainless steel needle, and the second electrode 312 is constructed as a stainless steel electrode plate. The second electrode 312 has a nine-square grid design with nine hollow holes. The first electrode 311 consists of nine unidirectional stainless steel needles, and the centers of the nine unidirectional stainless steel needles and the nine hollow holes are arranged in a one-to-one correspondence.

[0096] The characteristics of the charge grid component in Comparative Example 1 are as follows: the charge grid component includes only one charge unit, the first electrode is constructed as a unidirectional stainless steel needle, the second electrode is constructed as a stainless steel electrode plate, the stainless steel electrode plate is designed in a nine-square grid with nine hollow holes, there are nine unidirectional stainless steel needles, and the centers of the nine unidirectional stainless steel needles are set one-to-one with the centers of the nine hollow holes.

[0097] All other experimental parameters of the charged grid module 3 in Example 1 and the charged grid module in Comparative Example 1 are the same. The negative ion concentration in the charged grid module 3 of Example 1 is 10 million, while the negative ion concentration in the charged grid module of Comparative Example 1 is only 6.5 million. The CADR value of the charged grid module 3 of Example 1 is 500, where CADR is the Clean Air Delivery Rate, while the CADR value of the charged grid module of Comparative Example 1 is 400. The CADR value of the charged grid module 3 of Example 1 is increased by (500-400) / 400 = 25%. It can be clearly seen that by setting multiple charged units 31, the purification effect of the charged grid module 3 can be improved.
