Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

[0052] The air conditioner 1000 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0053] According to the air conditioner 1000 of the present utility model, Figure 1and Figure 2 As shown, the air conditioner 1000 comprises: an air duct component 100 and a purification component 200. The air duct component 100 defines an air duct 101 and has a disassembly opening 102. The purification component 200 comprises an electrostatic dust collecting assembly 20, which is detachably mounted on the air duct 101 through the disassembly opening 102.

[0054] The airflow flows along the air duct 101. The purification component 200 is disposed in the air duct 101 to purify the airflow in the air duct 101, thereby improving the cleanliness of the air outlet of the air conditioner 1000 and improving the indoor air quality. The air duct component 100 has a disassembly port 102, and the electrostatic dust collection component 20 is detachably installed in the air duct 101 through the disassembly port 102. The electrostatic dust collection component 20 can be disassembled, cleaned, and reused repeatedly, thereby reducing the use cost of the air conditioner 1000.

[0055] like Figure 3 and Figure 4 As shown, the electrostatic dust collection assembly 20 includes a mounting frame 1, an electrostatic net 2 and a conductive contact piece 3. The electrostatic net 2 is installed on the mounting frame 1, and the mounting frame 1 is pulled together with the air duct component 100. The conductive contact piece 3 is installed on the mounting frame 1 and connected to the lead-out line 21 of the electrostatic net 2.

[0056] The electrostatic net 2 is the main functional part of the electrostatic dust collecting component 20. The electrostatic net 2 can purify the air flowing through it. The electrostatic net 2 is installed on the mounting frame 1. The mounting frame 1 is the outer contour part of the electrostatic dust collecting component 20. The mounting frame 1 and the air duct 101 component are pulled together, and the conductive contact piece 3 and the lead-out wire 21 are connected to connect the electrostatic net 2 to the power supply to supply power to the electrostatic net 2.

[0057] Optionally, the electrostatic net 2 can be powered to generate a high-voltage electric field, which kills germs and captures dust to purify the airflow in the air duct 101. Alternatively, the electrostatic dust collection component 20 and the charging network cooperate with each other to purify the air, and the charging network can form a high-voltage electrostatic field, which is used to ionize the airflow flowing through the charging network to generate ions and electrons, either of which is attached to the dust particles in the airflow to charge the dust particles. The charged dust particles are easily attached to the electrostatic net 2, and the electrostatic dust collection component 20 filters and purifies the airflow, thereby reducing the dust particles in the airflow in the air duct 101 and improving the air quality of the air conditioner 1000.

[0058] like Figure 2 As shown, the purification component 200 further includes a power supply contact piece 4 which is disposed in the air duct 101 and is detachably electrically connected to the conductive contact piece 3 .

[0059] Among them, "detachable electrical contact connection" means that the electrostatic dust collecting component 20 and the power supply contact piece 4 are electrically connected through contact, and the electrostatic dust collecting component 20 and the power supply contact piece 4 can be disconnected by separation, and the contact and disconnection can be repeated many times without damaging the structure or causing adverse effects. As a result, the electrostatic dust collecting component 20 can be disassembled and assembled many times, reducing the wear and damage of the electrostatic dust collecting component 20 due to multiple disassembly and assembly, and extending the service life of the electrostatic dust collecting component 20.

[0060] When there is too much dust attached to the electrostatic net 2, the electrostatic dust collecting assembly 20 can be disassembled from the disassembly port 102, and the conductive contact piece 3 of the electrostatic dust collecting assembly 20 is separated from the power supply contact piece 4. The electrostatic dust collecting assembly 20 is not charged, and the electrostatic net 2 can be cleaned, such as by cleaning with a cleaning liquid, to remove the dust on the electrostatic net 2. After the electrostatic net 2 is cleaned, the electrostatic dust collecting assembly 20 can be reinstalled into the air duct 101 from the disassembly port 102, so that the conductive contact piece 3 of the electrostatic dust collecting assembly 20 is electrically connected to the power supply contact piece 4, so that the electrostatic dust collecting assembly 20 can work normally. As a result, the electrostatic dust collecting assembly 20 can be reused repeatedly. Compared with the use of HEPA net for filtering, the HEPA net needs to be replaced for filtering. The air conditioner 1000 of the embodiment of the utility model has a lower cost of use, and the electrostatic dust collecting assembly 20 can maintain the filtering effect at a better level by cleaning, which can improve the air supply quality of the air conditioner 1000.

[0061] According to the air conditioner 1000 of the embodiment of the utility model, the electrostatic dust collecting component 20 is detachably mounted on the air duct component 100 through the disassembly port 102, so that the electrostatic dust collecting component 20 can be dismantled and cleaned for repeated use, which is beneficial to reducing the use cost of the air conditioner 1000. In addition, the electrostatic dust collecting component 20 can be cleaned to maintain the filtering effect at a better level, which can improve the air supply quality of the air conditioner 1000.

[0062] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the mounting frame 1 includes a first frame 11 , and there are two conductive contact sheets 3 , both of which are arranged on the first frame 11 . The first frame 11 is provided with a water barrier rib 111 protruding between the two conductive contact sheets 3 .

[0063] The water-blocking rib 111 is arranged between the two conductive contacts 3, and the water-blocking rib 111 can prevent a water film from forming between the two conductive contacts 3. By arranging the water-blocking rib 111, when the user immediately installs the electrostatic dust collecting assembly 20 into the air duct 101 from the disassembly opening 102 after cleaning the electrostatic dust collecting assembly 20 without waiting for the water to dry, the water-blocking rib 111 can effectively prevent the water film between the two conductive contacts 3 from being connected, prevent the formation of a loop between the power supply contact 4, the conductive contact 3 and the water film to cause a short circuit, prevent the power supply contact 4 or the conductive contact 3 from being short-circuited and burned, and improve the working safety of the purification component 200.

[0064] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the first frame 11 is provided with not only water-blocking ribs 111 but also overflow openings 112 . The first frame 11 is provided with overflow openings 112 between each conductive contact sheet 3 and the water-blocking ribs 111 .

[0065] By setting the overflow port 112, the water between the two conductive contacts 3 can flow out from the overflow port 112, further preventing the formation of a water film between the two conductive contacts 3. When the user immediately installs the electrostatic dust collecting assembly 20 into the air duct 101 from the disassembly port 102 without waiting for the water to dry after cleaning the electrostatic dust collecting assembly 20, it can effectively prevent the water film between the two conductive contacts 3 from being connected, prevent the formation of a loop between the power supply contact 4, the conductive contact 3 and the water film to cause a short circuit, prevent the power supply contact 4 or the conductive contact 3 from being short-circuited and burned, and improve the working safety of the purification component 200.

[0066] In other embodiments of the present invention, Figure 5 and Figure 6 As shown, the mounting frame 1 includes a first frame 11 , and there are two conductive contact sheets 3 , both of which are arranged on the first frame 11 . The first frame 11 is provided with an overflow port 112 between the two conductive contact sheets 3 .

[0067] By setting the overflow port 112, the water between the two conductive contacts 3 can be discharged from the overflow port 112, preventing the water stored in the first frame 11 from being difficult to dry, and preventing the formation of a water film between the two conductive contacts 3. When the user immediately installs the electrostatic dust collecting assembly 20 from the disassembly port 102 into the air duct 101 without waiting for the water to dry after cleaning the electrostatic dust collecting assembly 20, the water flowing out of the overflow port 112 can effectively prevent the water film between the two conductive contacts 3 from being connected, prevent the formation of a loop between the power supply contact 4, the conductive contact 3 and the water film to cause a short circuit, prevent the power supply contact 4 or the conductive contact 3 from being short-circuited and burned, and improve the working safety of the purification component 200.

[0068] In some embodiments of the present invention, Figure 7As shown, the mounting frame 1 includes two second frames 12 disposed on both sides of the first frame 11 and arranged in parallel, and a third frame 13 connecting the two second frames 12 and arranged opposite to the first frame 11, each second frame 12 has a guide structure 121 that is pulled together with the air duct component 100, and at least one second frame 12 has a locking buckle 122 that is locked in position with the air duct component 100, as shown in FIG. Figure 8 As shown, a handle structure 131 is provided on the third frame 13 .

[0069] The conductive contact sheet 3 is installed on the first frame 11 of the mounting frame 1, and the two second frames 12 are respectively connected to the two ends of the first frame 11, and the second frames 12 and the air duct component 100 can be slidably matched. A guide structure 121 is provided on both second frames 12, and the movement stability of the mounting frame 1 relative to the air duct component 100 can be improved by providing the guide structure 121, which is conducive to the pulling, disassembly and installation of the mounting frame 1, and can improve the disassembly and assembly efficiency of the electrostatic dust collection assembly 20.

[0070] In addition, a locking buckle 122 is provided on one of the second frames 12, or a locking buckle 122 is provided on both second frames 12. After the electrostatic dust collecting component 20 is installed in the air duct component 100, the electrostatic dust collecting component 20 and the air duct component 100 are connected through the locking buckle 122, thereby improving the connection stability between the electrostatic dust collecting component 20 and the air conditioner 1000, reducing the shaking of the electrostatic dust collecting component 20 in the air duct component 100, and improving the working reliability of the electrostatic dust collecting component 20.

[0071] The conductive contact sheet 3 is installed on the first frame 11, and the first frame 11 is located further inside the air duct 101. The conductive contact sheet 3 is set away from the disassembly opening 102, which reduces the probability of accidental touch by the user and improves the safety of use. The third frame 13 is opposite to the first frame 11. The third frame 13 is farthest from the air duct 101 compared with the first frame 11 and the second frame 12. By setting a handle structure 131 on the third frame 13, it is convenient for the user to apply force to pull the electrostatic dust collection component 20 relative to the air duct component 100, which can improve the disassembly and assembly efficiency of the electrostatic dust collection component 20.

[0072] In some embodiments of the present invention, Figure 5 As shown, the electrostatic dust collecting assembly 20 is a rectangular member, the mounting frame 1 is the outer contour member of the electrostatic dust collecting assembly 20, the first frame 11 and the third frame 13 are arranged in parallel, and the two second frames 12 are connected between the first frame 11 and the third frame 13 and are arranged in parallel.

[0073] In some embodiments of the present invention, Figure 7As shown, the outer side of the second frame 12 has upper and lower protrusions protruding outward to form a slide groove in the middle. A slider is formed inside the air duct component 100, and the slider and the slide groove slide together to guide the electrostatic dust collection component 20 and improve the movement stability of the mounting frame 1 relative to the air duct component 100.

[0074] In some embodiments of the present invention, Figure 7 As shown, the locking buckle 122 on the second frame 12 and the air duct component 100 are engaged with each other to lock the electrostatic dust collecting component 20 relative to the air duct component 100. The locking buckle 122 can produce elastic deformation. When the electrostatic dust collecting component 20 is pushed into the air duct component 100 and installed in place, the locking buckle 122 can automatically deform to lock the mounting frame 1; when the electrostatic dust collecting component 20 is pulled out of the air duct component 100, the user applies force to deform the locking buckle 122 to release the lock on the mounting frame 1, and then the electrostatic dust collecting component 20 can be disassembled. By setting the locking buckle 122 and the air duct component 100 to engage with each other, the locking buckle 122 automatically deforms, which is convenient for users to use and can improve the efficiency of disassembly and assembly of the electrostatic dust collecting component 20.

[0075] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the mounting frame 1 includes a frame 1a and a frame cover 1b. A receiving cavity 14 is formed in the frame 1a. The electrostatic net 2 is received in the receiving cavity 14. The frame cover 1b is disposed on one side in the thickness direction of the electrostatic net 2 and cooperates with the frame 1a to limit the electrostatic net 2 from escaping from the receiving cavity 14. The conductive contact piece 3 is installed on the frame 1a.

[0076] During the installation process, the conductive contact piece 3 and the frame 1a are first installed, and then the electrostatic net 2 is placed in the accommodating cavity 14. Finally, the frame cover 1b is placed on the electrostatic net 2 and the frame 1a. The frame 1a and the frame cover 1b jointly restrict the electrostatic net 2.

[0077] It is worth noting that if Figure 3 As shown, both the frame 1a and the frame cover 1b are provided with openings for airflow to pass through, and the mounting frame 1 has little obstruction to the airflow, and the airflow can flow along the air duct 101 after passing through the frame 1a, the electrostatic net 2 and the frame cover 1b, and the electrostatic net 2 can purify the airflow.

[0078] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the electrostatic dust collecting assembly 20 is pulled together with the air duct component 100 in the horizontal direction. When the electrostatic dust collecting assembly 20 is in normal working state, the frame cover 1b is located above the frame 1a, and the frame cover 1b restricts the electrostatic net 2 within the frame 1a from top to bottom.

[0079] In some embodiments of the present invention, Figure 7As shown, the frame 1a includes a frame 1a1 and a bottom frame 1a2, the frame 1a1 is arranged around the bottom frame 1a2 to form a receiving cavity 14 between the frame 1a1 and the bottom frame 1a2, and the bottom frame 1a2 and the frame cover 1b are respectively arranged on both sides of the thickness direction of the electrostatic net 2. The frame 1a1 is provided with a slot 113 that is recessed from the frame cover 1b to the bottom frame 1a2, and the conductive contact 3 is plugged into the slot 113.

[0080] The conductive contact piece 3 is installed in the direction from the frame cover 1b to the bottom frame 1a2 and inserted into the slot 113 to install the conductive contact piece 3 on the frame 1a. The plug-in installation method of the conductive contact piece 3 is simple to operate and can improve the assembly efficiency of the electrostatic dust collection assembly 20.

[0081] In some embodiments of the present invention, Fig. 9 As shown, the slot 113 includes two sub-slots 1131 spaced apart along the length direction of the frame 1a1, and a first buckle 114 located between the two sub-slots 1131 is protruded on the outer wall of the frame 1a1. The first buckle 114 is arranged at one end of the frame 1a1 close to the frame cover 1b, as shown in FIG. Figure 6 As shown, the first buckle 114 stops the conductive contact sheet 3 from being separated from the slot 113 along the direction from the bottom frame 1a2 to the frame cover 1b.

[0082] like Fig.10 As shown, the conductive contact piece 3 has a connection portion 33 that is inserted into the sub-slot 1131, and the connection portion 33 is matched with the sub-slot 1131 in a one-to-one manner. The conductive contact piece 3 has two connection portions 33, and the connection portions 33 are arranged at intervals along the length direction of the frame 1a1. The conductive contact piece 3 is inserted into the slot 113 through the connection portion 33, that is, it is restricted from moving along the length direction of the frame 1a1, thereby improving the installation stability of the conductive contact piece 3. In addition, by providing two connection portions 33 and two sub-slots 1131 that are matched in a one-to-one manner, the installation stability of the conductive contact piece 3 can be further improved.

[0083] The slot 113 is recessed from the frame cover 1b toward the bottom frame 1a2, and the conductive contact 3 is inserted into the slot 113. The slot 113 can also limit the conductive contact 3 from moving toward the bottom frame 1a2. By providing the first buckle 114, the first buckle 114 stops at one end of the conductive contact 3 close to the frame cover 1b, and the first buckle 114 can limit the conductive contact 3 from moving toward the frame cover 1b. The movement of the conductive contact 3 along the thickness direction of the electrostatic net 2 is limited, and the installation stability of the conductive contact 3 is strong.

[0084] like Fig. 9As shown, by arranging the first buckle 114 between the two sub-grooves 1131, the first buckle 114 can be elastically deformed in a direction perpendicular to the length direction of the frame 1a1, and when the conductive contact piece 3 is inserted into the slot 113 from the frame cover 1b to the bottom frame 1a2, the first buckle 114 can be driven to produce elastic deformation to avoid the movement of the conductive contact piece 3. After the conductive contact piece 3 is installed in place, the first buckle 114 is restored to its original position, and the first buckle 114 is stopped at one end of the conductive contact piece 3 close to the frame cover 1b, so as to limit the conductive contact piece 3 from being separated from the slot 113 in the direction from the bottom frame 1a2 to the frame cover 1b.

[0085] In some embodiments of the present invention, Fig. 9 As shown, a reinforcing rib 115 is protruded from the outer wall of the frame 1a1 and is located between the two sub-grooves 1131. The reinforcing rib 115 extends from the first buckle 114 to the bottom frame 1a2. Figure 6 As shown, the conductive contact piece 3 includes an electric contact portion 31 located outside the frame 1 a 1 and between two sub-grooves 1131 , and the reinforcing rib 115 supports the electric contact portion 31 .

[0086] Since two sub-grooves 1131 are adjacently arranged on the frame 1a1, the structural stability of the portion sandwiched between the two sub-grooves 1131 is reduced. Therefore, a reinforcing rib 115 is arranged between the two sub-grooves 1131 to improve the structural stability, reduce shaking, and improve the installation stability of the conductive contact piece 3.

[0087] The reinforcing rib 115 extends from the first buckle 114 to the bottom frame 1a2, and the reinforcing rib 115 abuts against the outer portion of the conductive contact piece 3 located on the frame 1a1. The electrical contact portion 31 of the conductive contact piece 3 abuts against the reinforcing rib 115, which can limit the conductive contact piece 3 from moving toward the inside of the accommodating cavity 14 along the thickness direction of the frame 1a1, further limiting the position of the conductive contact piece 3.

[0088] In some embodiments of the present invention, Fig.10 As shown, the conductive contact piece 3 also includes a stop portion 32. Along the length direction of the frame 1a1, both sides of the electrical contact portion 31 are connected with the stop portion 32. The stop portion 32 stops at the inner side of the frame 1a1 and is connected to the lead wire 21 of the electrostatic network 2.

[0089] The abutting portion 32 abuts against the inner side of the frame 1a1, which can limit the conductive contact 3 from moving toward the outside of the accommodating cavity 14 along the thickness direction of the frame 1a1, further limiting the position of the conductive contact 3. By designing the shape of the conductive contact 3 and cooperating with the slot 113 and the first buckle 114, the six degrees of freedom of the conductive contact 3 are restricted after being installed in the frame 1a1, and the installation stability of the conductive contact 3 is strong, the shaking is reduced, and the working reliability of the conductive contact 3 is improved.

[0090] like Fig.10As shown, the middle part of the conductive contact piece 3 is an electric contact part 31 located outside the frame 1a1, and the electric contact part 31 extends along the length direction of the frame 1a1. The two sides of the electric contact part 31 are respectively provided with stop parts 32 located inside the frame 1a1. The electric contact part 31 and the stop part 32 are arranged in parallel, and a connecting part 33 is connected between the electric contact part 31 and the stop part 32. The connecting part 33 is arranged perpendicular to the electric contact part 31 and the stop part 32. Among them, the electric contact part 31 and the power supply contact piece 4 are detachably connected in electric contact, the stop part 32 is connected to the lead-out line 21 of the electrostatic network 2, and the connecting part 33 is connected between the electric contact part 31 and the stop part 32, so that the conductive contact piece 3 conducts electricity to the electrostatic network 2.

[0091] In some embodiments of the present invention, the conductive contact piece 3 is an integrally formed part.

[0092] In some embodiments of the present invention, Figure 7 As shown, the frame 1a1 includes two second frames 12 arranged in parallel and opposite to each other, and a first frame 11 and a third frame 13 connecting the two second frames 12 and arranged opposite to each other, the conductive contact piece 3 is installed on the first frame 11, and each second frame 12 is snap-fitted with the frame cover 1b. The snap-fitting of the frame cover 1b and the second frame 12 of the frame 1a facilitates assembly and improves the assembly efficiency of the electrostatic dust collection assembly 20.

[0093] like Fig.11 As shown, the frame cover 1b is provided with a latching protrusion 15 extending toward the frame 1a, and a latching groove 151 is provided on the latching protrusion 15. Figure 7 As shown, a second buckle 123 is provided on the second frame 12. Fig.14 As shown, when the frame cover 1b is placed on the electrostatic net 2, the latch 15 extends between the electrostatic net 2 and the second frame 12, and the second buckle 123 and the latch groove 151 on the second frame 12 are engaged with each other, thereby connecting the frame 1a and the frame cover 1b, and thus confining the electrostatic net 2 in the accommodating cavity 14.

[0094] like Fig.11 As shown, the frame cover 1b is provided with a latching protrusion 15 corresponding to the two second side frames 12, and two latching protrusions 15 are provided corresponding to each second side frame 12. The frame cover 1b and the frame 1a are snap-fitted through four second clips 123 and slots 151, and the four second clips 123 and slots 151 are arranged at intervals in the length and width directions of the electrostatic dust collection assembly 20, and the force is evenly applied, which can improve the connection stability of the frame cover 1b and the frame 1a.

[0095] In some embodiments of the present invention, Fig.11 As shown, the frame cover 1b is provided with an escape groove 16 for escaping the first buckle 114 at a position corresponding to the first frame 1a, thereby improving the installation stability of the frame cover 1b and the frame 1a.

[0096] In some embodiments of the present invention, Figure 11-Figure 14 As shown, the frame 1a and the frame cover 1b are snap-connected, and the entire circumference of the frame cover 1b is bonded to the frame 1a by means of colloid.

[0097] The frame cover 1b and the frame 1a are snap-fitted together to facilitate assembly and improve the assembly efficiency of the electrostatic dust collection assembly 20; after the frame 1a and the frame cover 1b are snap-fitted, they are then bonded to the frame 1a through the entire circumferential edge, which can improve the connection stability between the frame cover 1b and the frame 1a and reliably limit the electrostatic net 2 in the accommodating cavity 14.

[0098] It is worth noting that after the frame cover 1b, the electrostatic net 2, the frame 1a and the conductive contact sheet 3 are assembled and formed into an integrated piece by gluing the frame cover 1b and the frame 1a, when the user removes the electrostatic dust collecting assembly 20 for cleaning, the electrostatic dust collecting assembly 20 can be cleaned directly as a whole without having to disassemble the frame cover 1b and the frame 1a to take out the electrostatic net 2 from the accommodating cavity 14, which reduces the difficulty of operation and facilitates the user to clean the electrostatic dust collecting assembly 20. Therefore, the gluing of the frame cover 1b and the frame 1a can also prevent the user from disassembling the frame cover 1b and the frame 1a by mistake, which plays a fool-proof role.

[0099] In some embodiments of the present invention, the entire circumferential edge of the frame cover 1b is bonded to the frame 1a by hot melt adhesive, which can prevent the frame cover 1b from warping and improve the structural stability of the electrostatic dust collection assembly 20.

[0100] In some embodiments of the present invention, Fig.10 As shown, an electrostatic resistor 22 is connected in series to the lead wire 21 .

[0101] By connecting the electrostatic resistor 22 in series with the lead-out wire 21, after the conductive contact piece 3 and the power supply contact piece 4 are powered off, the electrostatic resistor 22 can quickly consume the charge in the electrostatic dust collecting assembly 20. This prevents the user from being electrocuted by the charge by touching the conductive contact piece 3 on the frame 1a immediately after the electrostatic dust collecting assembly 20 is pulled out, and can effectively prevent the user from feeling an electric shock when touching the conductive contact piece 3.

[0102] In some embodiments of the present invention, the lead wire 21 and the conductive contact piece 3 are connected by welding, and the welding position between the lead wire 21 and the conductive contact piece 3 is covered by an insulating member.

[0103] After the conductive contact piece 3 is installed on the frame 1a, the lead wire 21 and the conductive contact piece 3 are welded and connected to improve the connection stability. The welding position of the lead wire 21 and the conductive contact piece 3 is covered with an insulating member to prevent the liquid from contacting the electrical connection point when cleaning the electrostatic dust collection component 20 and causing a short circuit, thereby improving the safety of use.

[0104] By outsourcing the welding positions of the lead wires 21 and the conductive contacts 3 with insulating parts, the electrostatic dust collecting assembly 20 can be directly cleaned as a whole without worrying about damaging the internal electrical components. It is also not necessary to detach the frame cover 1b and the frame 1a and remove the electrostatic net 2 from the accommodating cavity 14 for separate cleaning, which reduces the difficulty of operation and facilitates the user to clean the electrostatic dust collecting assembly 20.

[0105] In some embodiments of the utility model, the steps of installing the conductive contact piece 3 are as follows: first, the conductive contact piece 3 is installed on the frame 1a of the electrostatic dust collecting net assembly, and the first buckle 114 limits the conductive contact piece 3; then the electrostatic net 2 is installed in the accommodating cavity 14 of the frame 1a; then the lead wire 21 on the electrostatic net 2 is welded to the conductive contact piece 3; finally, the position where the lead wire 21 is welded to the conductive contact piece 3 is tightly sealed by hot melt adhesive to prevent the two electrodes from short-circuiting during water washing.

[0106] In some embodiments of the present invention, Figure 2 , Fig.15 and Fig.16 As shown, the purification component 200 further includes a charging network component 40 , which is disposed in the air duct 101 , and the electrostatic dust collection component 20 is located downstream of the charging network component 40 along the air flow direction of the air duct 101 .

[0107] The charging grid assembly 40 can form a high-voltage electrostatic field, which is used to ionize the airflow passing through the charging grid assembly 40 to generate ions and electrons, either of which is attached to dust particles in the airflow to charge the dust particles.

[0108] Charged dust particles are easily attached to the electrostatic net 2. Optionally, the electrostatic dust collection component 20 can be provided with a positive electrode and a negative electrode. The electrons can make the dust particles encountered on the way negatively charged in the process of rushing to the positive electrode, and the negatively charged dust particles are adsorbed onto the positive electrode for collection. The ions can make the dust particles encountered on the way positively charged in the process of rushing to the negative electrode, and the positively charged dust particles can be adsorbed onto the negative electrode for collection, thereby eliminating the dust particles in the air and improving the air quality of the air conditioner 1000.

[0109] Alternatively, the electrostatic dust collecting assembly 20 may be provided with a positive electrode sheet, and the electrons may negatively charge the dust particles encountered on the way when rushing to the positive electrode sheet, and the negatively charged dust particles are adsorbed on the positive electrode sheet to be collected. Thus, the air quality of the air conditioner 1000 is improved.

[0110] like Fig.17As shown, the charging network component 40 includes a high-voltage package, a charging network, a micro switch 5 and a power supply contact 4. The high-voltage package is electrically connected to the charging network and the power supply contact 4 respectively. The high-voltage package supplies power to the electrostatic dust collecting component 20 through the power supply contact 4. The micro switch 5 is connected in series on the connection path between the high-voltage package and the power supply contact 4. The micro switch 5 is suitable for being triggered by the electrostatic dust collecting component 20 assembled with the air duct component 100 and switched to a closed state. There are two power supply contacts 4, and the micro switch 5 is located between the two power supply contacts 4.

[0111] The high-voltage package integrates components such as battery cells and PCB boards. The high-voltage package has a power supply function and is used to supply power to the charging network component 40 and the electrostatic dust collection component 20. The charging network component 40 and the electrostatic dust collection component 20 share a high-voltage package for power supply, which can reduce the number of high-voltage packages, simplify the structural complexity, and facilitate the arrangement of the purification component 200.

[0112] The high-voltage package is connected to the power supply contact piece 4, and the power supply contact piece 4 is electrically connected to the conductive contact piece 3 to supply power to the electrostatic dust collection component 20. When the electrostatic dust collection component 20 is assembled in place in the air duct component 100, the micro switch 5 is in a closed state, and the high-voltage package is electrically connected to the power supply contact piece 4, so that the electrostatic dust collection component 20 can be electrically connected to the high-voltage package through the conductive contact piece 3. When the electrostatic dust collection component 20 is removed from the air duct component 100, the micro switch 5 automatically resets and pops open, and the micro switch 5 switches to the disconnected state, thereby separating the high-voltage package and the power supply contact piece 4, and the high-voltage package stops working, and the high-voltage package stops supplying power to the charging grid and the electrostatic dust collection component 20.

[0113] Through the above arrangement, the power supply contact piece 4 and the charging network can be de-energized after the electrostatic dust collecting assembly 20 is disassembled, so as to avoid electric shock caused by accidental touch by users (especially children), which is beneficial to improving safety.

[0114] Specifically, the micro switch 5 is located between the two power supply contacts 4. When the electrostatic dust collection component 20 is assembled in place in the air duct component 100, the conductive contact 3 contacts the power supply contact 4, and the electrostatic dust collection component 20 also contacts the micro switch 5 to trigger the micro switch 5 to switch to a closed device, and the high-voltage package can supply power to the electrostatic dust collection component 20. When the electrostatic dust collection component 20 is separated from the power supply contact 4, the electrostatic dust collection component 20 is also separated from the micro switch 5, and the micro switch 5 automatically resets and switches to the disconnected state, preventing the user from touching the charging network component 40 or the electrostatic dust collection component 20 at this time and causing an electric shock accident, thereby improving the safety of the user disassembling and assembling the electrostatic dust collection component 20.

[0115] In some embodiments of the present invention, the electrostatic dust collecting component 20 is arranged above the charging network component 40, the airflow direction in the air duct 101 flows from bottom to top, and the electrostatic dust collecting component 20 and the charging network component 40 are arranged at intervals to improve the movement smoothness of the electrostatic dust collecting component 20 and reduce the pulling and wear of the electrostatic dust collecting component 20.

[0116] A boss is provided above the charging network component 40, and a power supply contact 4 and a micro switch 5 are provided on the side of the boss facing the disassembly port 102. When the electrostatic dust collecting component 20 is installed from the disassembly port 102 to the air duct 101 component, the conductive contact 3 on the first frame 1a of the electrostatic dust collecting component 20 contacts the power supply contact 4 for conduction, and the first frame 1a of the electrostatic dust collecting component 20 contacts the micro switch 5 and switches to a closed state.

[0117] In some embodiments of the present invention, Fig.18 and Fig.19 As shown, the air conditioner 1000 further includes a rear box component 300 and a panel component 400 , wherein the panel component 400 is located at the front side of the air conditioner 1000 , the rear box component 300 is located at the rear side of the air conditioner 1000 , and the duct component 100 and the purification component 200 are arranged between the panel component 400 and the rear box component 300 .

[0118] In some embodiments of the present invention, the duct component 100 and the purification component 200 are arranged at the lower part of the air conditioner 1000, and the panel component 400 includes an upper panel 401 located above and a lower panel 402 located below, and the duct component 100 and the purification component 200 are arranged opposite to the lower panel 402.

[0119] In some embodiments of the utility model, the air inlet of the duct component 100 is connected to the outdoor side, and the air outlet of the duct component 100 is connected to the indoor side. The duct component 100 can deliver fresh air into the room, and the purification component 200 absorbs dust particles in the fresh air flow. Therefore, the fresh air quality of the air conditioner 1000 can be improved, and the practicality of the air conditioner 1000 is improved.
