To this end, an embodiment of the present utility model provides an air conditioner, including: the shell is provided with an air duct; the heat exchanger and the wind wheel are arranged in the air duct, and a gap is arranged between the heat exchanger and the wind wheel; the sterilizing device is arranged in the gap and comprises a discharging assembly, the discharging assembly comprises an emitter and a plurality of groups of receiving poles, the emitter comprises a conductive body and two discharging parts, the conductive body is of a plate-shaped structure, the two discharging parts are oppositely arranged at two ends of the conductive body in the width direction, and the discharging parts comprise a plurality of discharging tips arranged along the length direction of the conductive body; each group of receiving poles comprises two rod-shaped receiving poles, and the receiving poles extend along the length direction of the conductive body; a group of receiving poles are arranged on two sides of the width direction of the conductive body, and two receiving poles of each group are respectively arranged on two sides of the thickness direction of the conductive body; the two groups of receiving poles are arranged at intervals opposite to the two discharging parts of the emitter, so that the two discharging parts of the emitter can discharge ionized air to generate sterilizing substances.

Wherein, sterilizing equipment mainly plays the bactericidal effect. The sterilizing device can generate discharge (can be in the discharge forms of, but not limited to, streamer discharge, corona discharge, tip discharge, dielectric barrier discharge and the like) under the action of a high-voltage power supply, and ionizes air through a strong electric field to generate sterilizing substances, wherein the sterilizing substances can comprise strong oxidizing substances, and the strong oxidizing substances can oxidize and decompose bacteria in the air, so that the sterilizing effect is achieved. And, the discharge assembly includes an emitter electrode and at least two sets of receiver electrodes. The emitter may be a high voltage pole connected to the high voltage end of the high voltage power supply. The receiving electrode can be a low-voltage electrode or a grounding electrode, and is connected with a low-voltage end or a grounding end of the high-voltage power supply. Alternatively, the connection modes of the emitter and the receiving electrode and the high-voltage power supply can be exchanged, and the emitter can be a grounding electrode or a low-voltage electrode, and the receiving electrode can be a high-voltage electrode.

The emitter comprises a conductive body and two discharge parts which are respectively arranged at two ends of the conductive body in the width direction, a group of receiving poles are arranged opposite to each discharge part, and the two receiving poles of each group are respectively arranged at two sides of the conductive body in the thickness direction. Therefore, one emitter can correspond to two groups of receiving poles, so that two strong electric fields are formed, more sterilizing substances can be generated, one emitter is omitted, the structure of the purifying and sterilizing device is simplified, and the production cost is reduced. Each discharge part comprises a plurality of discharge tips, and the discharge tips can strengthen the discharge intensity, so that the ionization degree of the air is strengthened, and more sterilizing substances are generated.

Therefore, the discharge tip of the discharge portion is also tapered in the width direction of the conductive body. Therefore, one conducting strip can be directly machined and molded to obtain the integrally molded emitter, and compared with the scheme that the needle-shaped structure is inserted or welded on the plate surface of the plate-shaped structure to form the discharge tip, the machining difficulty of the scheme is low, and the machining and molding are convenient. The width of the conductive body may be greater than the protruding length of the discharge tip (i.e., the dimension of the discharge tip in the width direction of the conductive body). Therefore, a certain distance is reserved between the two discharging parts of one emitter, and the emitter breakdown damage caused by the mutual influence is not easy to occur during discharging, so that the use reliability of the emitter is guaranteed.

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

The embodiment of the utility model provides an air conditioner, which comprises: a housing 3 and a sterilizing device 2.

Specifically, as shown in fig. 4 to 10, the casing 3 is provided with an air duct having an air outlet 32 and an air inlet 31. The air outlet 32 may be provided with an air guiding vane 34 and an air guiding plate 33, as shown in fig. 6 and 7. The air deflector 33 may open or close the air outlet 32. A primary filter screen may be disposed at the air inlet 31.

The air duct is internally provided with a heat exchanger 4 and a wind wheel 5. A gap 35 is provided between the heat exchanger 4 and the wind wheel 5. When the air conditioner works, the wind wheel 5 rotates, air enters the machine shell 3 from the air inlet 31, exchanges heat with the heat exchanger 4, and is discharged from the air outlet 32. The wind wheel 5 may be, but is not limited to, a cross flow wind wheel.

As shown in fig. 4 to 10, the sterilizing device 2 is disposed in the housing 3 and in the gap 35 between the heat exchanger 4 and the wind wheel 5, as shown in fig. 6 and 7. The sterilization device 2 comprises a discharge assembly. As shown in fig. 1 to 3, the discharge assembly includes an emitter electrode 21 and a plurality of sets of receiving electrodes 22. The emitter 21 includes a conductive body 211 and two discharge portions 212. The conductive body 211 has a plate-like structure. The two discharging parts 212 are disposed opposite to each other at both ends of the conductive body 211 in the width direction, and the discharging part 212 includes a plurality of discharging tips 2121 disposed along the length direction of the conductive body 211. Each set of the receiving poles 22 includes two bar-shaped receiving poles 22, and the receiving poles 22 extend along the length direction of the conductive body 211. The rod-shaped receiving electrode 22 may be a solid rod or a hollow rod.

A set of receiving poles 22 is disposed on both sides of the width direction of the conductive body 211, and two receiving poles 22 of each set are disposed on both sides of the thickness direction of the conductive body 211, as shown in fig. 2 and 3. The two sets of receiving poles 22 (i.e., the two sets of receiving poles 22 on both sides) are disposed at intervals respectively opposite to the two discharge portions 212 of the emitter 21, so that the two discharge portions 212 of the emitter 21 can discharge ionized air to generate sterilizing substances.

Wherein the sterilization device 2 mainly plays a role in sterilization. The sterilization device 2 may generate electric discharge (may be, but not limited to, a discharge form such as streamer discharge, corona discharge, tip discharge, dielectric barrier discharge, etc.) under the action of a high-voltage power supply, ionize air by a strong electric field to generate a sterilization substance, and the sterilization substance may include a strong oxidizing substance, and the strong oxidizing substance may oxidize and decompose bacteria in the air, thereby playing a role in sterilization. And, the discharge assembly includes an emitter electrode 21 and at least two sets of receiving poles 22. The emitter 21 may be a high voltage pole connected to the high voltage terminal of a high voltage power supply. The receiving pole 22 may be a low voltage pole or a ground pole, and is connected to a low voltage terminal or a ground terminal of a high voltage power supply. Alternatively, the connection modes of the emitter 21 and the receiving electrode 22 with the high-voltage power supply may be exchanged, and the emitter 21 may be a ground electrode or a low-voltage electrode, and the receiving electrode 22 may be a high-voltage electrode.

The emitter 21 includes a conductive body 211 and two discharge portions 212 provided at both ends of the conductive body 211 in the width direction, each discharge portion 212 being provided opposite to a group of receiving poles 22, and two receiving poles 22 of each group being separated at both sides of the conductive body 211 in the thickness direction, as shown in fig. 2 and 3. Thus, one emitter 21 can correspond to two groups of receiving poles 22, so that two strong electric fields are formed, more sterilizing substances are generated, one emitter 21 is omitted, the structure of the sterilizing device 2 is simplified, and the production cost is reduced.

Each of the discharge parts 212 includes a plurality of discharge tips 2121, and the discharge tips 2121 may strengthen the intensity of the discharge, thereby strengthening the degree of ionization of air, which is advantageous for generating more sterilizing substances. The shape of the discharge tip 2121 may be, but is not limited to: triangle, trapezoid, saw tooth, etc. The plurality of discharge tips 2121 of each discharge portion 212 may be disposed at intervals (e.g., equally spaced), or may be close together without intervals. The two discharge portions 212 may be symmetrically disposed at both ends of the conductive body 211, or may be suitably staggered in the longitudinal direction of the conductive body 211.

The conductive body 211 has a plate-like structure (or a sheet-like structure), and may have a long strip shape (e.g., a rectangular shape), and two discharge portions 212 are disposed opposite to each other at two ends of the conductive body 211 in the width direction and face two sets of receiving poles 22 disposed at two sides of the conductive body 211 in the width direction. Accordingly, the discharge tip 2121 of the discharge portion 212 is also tapered in the width direction of the conductive body 211. Thus, a conductive sheet can be directly processed and molded to obtain the integrally molded emitter 21, and compared with the scheme that the needle-shaped structure is inserted or welded on the plate surface of the plate-shaped structure to form the discharge tip 2121, the scheme has lower processing difficulty and is convenient for processing and molding. The width of the conductive body 211 may be greater than the protruding length of the discharge tip 2121 (i.e., the dimension of the discharge tip 2121 in the width direction of the conductive body 211). In this way, a certain distance is provided between the two discharging portions 212 of one emitter 21, so that the emitter 21 is not easily broken down and damaged due to mutual influence during discharging, thereby being beneficial to ensuring the use reliability of the emitter 21.

The sterilizing device 2 is arranged in the casing 3 and is positioned at a gap 35 between the heat exchanger 4 and the wind wheel 5, and sterilizing substances (such as strong oxidizing substances) generated by the sterilizing device 2 can be diffused to each corner of the inner cavity of the air conditioner in the casing 3 under the state that the air outlet 32 of the air conditioner is closed, so that the sterilization in the cavity is realized. In the state that the air conditioner opens the air outlet 32, the sterilizing material generated by the sterilizing device 2 can also diffuse into the indoor space along with the air outlet of the air conditioner, so as to perform a sterilizing function on the indoor space.

Therefore, the air conditioner provided by the embodiment of the utility model not only can realize the sterilization of space bacteria, but also can sterilize bacteria attached to the inner cavity (such as the structures of the wind wheel 5, the heat exchanger 4 and the like) of the air conditioner, and has the advantages of simple structure and high reliability.

And, compare in setting up the air intake 31 department or air outlet 32 departments with sterilizing equipment 2 at the air conditioner, this scheme sets up sterilizing equipment 2 in the clearance 35 department between heat exchanger 4 and wind wheel 5, when sterilizing the air conditioner inner chamber, sterilizing material that sterilizing equipment 2 discharge produced can diffuse to heat exchanger 4 and wind wheel 5 of its both sides fast to can play the high-efficient bactericidal effect to heat exchanger 4 and wind wheel 5, be favorable to improving intracavity sterilization efficiency, shorten the duration of intracavity sterilization.

The discharge assembly is arranged on the mounting frame 1 and is located in the air flow channel 13. The mounting frame 1 mainly plays a mounting role. On the one hand, the mounting frame 1 provides mounting carriers for the emitter electrode 21 and the receiver electrode 22, and ensures the stability and reliability of the mounting carriers. The mounting frame 1 can be provided with a corresponding structure to be connected with a corresponding structure of an air conditioner so as to ensure the stability and reliability of the sterilizing device 2 mounted on the air conditioner. The connection structure may include a mechanical connection structure, such as may be achieved by, but not limited to: the mechanical connection is carried out in a screw connection mode, a buckle connection mode and the like; the connection structure may also include an electrical connection structure, for example, a connection terminal may be disposed to electrically connect with a power supply of the air conditioner.

Of course, the sterilizing device 2 may not include the mounting frame 1, and for example, the emitter 21 and the receiver 22 may be directly mounted on a corresponding structure (such as the casing 3) of the air conditioner.

In some exemplary embodiments, the width direction of the conductive body 211 is perpendicular to the arrangement direction of the two receiving poles 22 of each group, as shown in fig. 2.

In other words, the two receiving poles 22 of each group are arranged side by side in the thickness direction of the conductive body 211. The two sets of receiving poles 22 are juxtaposed in the width direction of the conductive body 211. The two receiving poles 22 of each group may be symmetrically disposed at both sides of the emitter 21 in the thickness direction. The two sets of receiving poles 22 may be symmetrically disposed at both sides of the emitter 21 in the width direction. In this way, the arrangement of the emitter electrode 21 and the receiver electrode 22 is relatively regular, and the emitter electrode and the receiver electrode are convenient to assemble and fix on the mounting frame 1.

In some exemplary embodiments, as shown in fig. 2, the mounting bracket 1 includes a mounting seat 11 and a mounting cover 12, and the mounting seat 11 is in cover connection with the mounting cover 12. The emitter 21 and the receiver 22 are fixed to the mounting cover 12. The mounting seat 11 and the mounting cover 12 can be fixedly connected by means of a buckle, a fastener (such as a screw) and the like. The emitter 21 and the receiver 22 may be fixedly connected to the mounting cover 12 by means of a buckle, a fastener (e.g., a screw), or the like.

In one embodiment, the mounting seat 11 is provided with a clamping protrusion, and the mounting cover 12 is correspondingly provided with a clamping buckle, and the clamping buckle is clamped on the clamping protrusion, so that the mounting cover 12 is connected with the mounting seat 11.

The mounting cover 12 may be provided with a slot, and the grounding electrode and the emitter 21 may be inserted into the slot at the end.

Of course, the structural form of the mount 1 is not limited thereto, and the mounting positions and fixing modes of the emitter electrode 21 and the receiver electrode 22 are not limited thereto, as long as the emitter electrode 21 and the receiver electrode 22 can be fixed.

In some exemplary embodiments, the airflow channel 13 is provided with a plurality of vents 131, as shown in fig. 2, the plurality of vents 131 being disposed along the circumference of the mounting bracket 1.

Thus, the sterilizing device can release sterilizing substances outwards through the plurality of ventilation openings 131, which is favorable for better diffusion of the sterilizing substances in the inner cavity of the air conditioner, thereby playing a better sterilizing effect on the inner cavity of the air conditioner. In addition, the air flow direction of the air flow channel 13 can be freely changed according to the change of the ambient air pressure, and each ventilation opening 131 can be used as an air inlet or an air outlet under different conditions, so that the installation difficulty of the sterilizing device is reduced, the sterilizing device is convenient to install on an air conditioner (or other air treatment equipment), and the application range of the sterilizing device is enlarged.

In one embodiment, the mounting frame 1 is substantially rectangular parallelepiped, and the length direction of the receiving electrode 22 coincides with the length direction of the mounting frame 1. The mounting frame 1 is provided with four ventilation openings 131, and the four ventilation openings 131 are arranged along the circumferential direction of the mounting frame 1, as shown in fig. 2.

In some exemplary embodiments, the discharge assembly includes a plurality of emitters 21, such as two, three, or even more emitters 21, disposed at intervals along the thickness direction of the conductive body 211, and each emitter 21 is disposed at an opposite interval from two sets of receiving poles 22. The thickness direction of the conductive body 211 may be identical to the thickness direction of the sterilization device 2. Thus, this solution is equivalent to the effect that the discharge assembly of the sterilization apparatus 2 realizes array arrangement in the thickness direction of the sterilization apparatus 2, and does not increase the volume of the sterilization apparatus 2.

In some exemplary embodiments, the discharge assembly includes a plurality of emitters 21 spaced apart in a width direction of the conductive body 211, and at least one set of receiving poles 22 is provided between any adjacent two of the emitters 21 in the width direction of the conductive body 211. The width direction of the conductive body 211 may be identical to the width direction of the sterilization device 2. Thus, this solution corresponds to the effect that the discharge assembly of the sterilizing device 2 achieves an array arrangement in the width direction of the sterilizing device 2.

In some exemplary embodiments, a plurality of discharge assemblies may be disposed side by side in the length direction of the sterilization apparatus 2, so as to achieve an array arrangement effect in the length direction.

A portion of the rotor is located within the semi-enclosed structure. The gap between the wind wheel 5 and the heat exchanger 4 is also located in the semi-enclosed structure, so that the sterilization device 2 is also located in the semi-enclosed structure.

The heat exchanger 4 is arranged into a plurality of mutually connected sub heat exchangers 41, which is beneficial to increasing the heat exchange area of the heat exchanger 4 and further beneficial to improving the heat exchange efficiency of the air conditioner. Part of the wind wheel is positioned in the semi-surrounding structure, which is beneficial to increasing the wind passing area of the heat exchanger 4 and further improving the heat exchange efficiency of the air conditioner.

The plurality of sub heat exchangers 41 may be connected to each other in the circumferential direction of the wind wheel to form a semi-enclosed structure. Each sub heat exchanger 41 may extend in the axial direction of the wind wheel, and the length direction of the heat exchanger 4 may coincide with the axial direction of the wind wheel 5.

The longitudinal direction of the gap 35 and the longitudinal direction of the heat exchanger 4 may coincide with the longitudinal direction of the casing 3.

Alternatively, the cross section of the gap 35 extends along the length of the heat exchanger 4, and the length of the gap 35 is also aligned with the axial direction of the rotor 5. The sterilizing device 2 is provided in the edge region in the longitudinal direction of the gap 35, as shown in fig. 5, 8 and 9.

This is advantageous in reducing the wind resistance caused to the gap 35 by the existence of the sterilization apparatus 2, and in improving the air outlet efficiency of the air conditioner.

In some embodiments, 50 mm.ltoreq.k1.ltoreq.120 mm.

Thus, sterilizing substances generated by the sterilizing device 2 during the sterilization in the cavity can diffuse to two sides along the length direction of the heat exchanger 4, which is beneficial to improving the sterilization efficiency in the cavity and shortening the time required by the sterilization in the cavity. In addition, it is ensured that the sterilizing device 2 can pass through the air at both sides of the gap 35 in the length direction, so that the sterilizing material generated by the sterilizing device 2 can be fully contacted with the air in the state that the air outlet 32 of the air conditioner is opened, and the space sterilizing efficiency is improved.

When the sterilization apparatus 2 includes the mounting frame 1, the distance k1 between the end of the heat exchanger 4 adjacent to the sterilization apparatus 2 in the length direction and the sterilization apparatus 2 may be a distance between the end of the heat exchanger 4 adjacent to the mounting frame 1 in the length direction and the mounting frame 1.

In some exemplary embodiments, the number of sterilization devices 2 is one, as shown in fig. 5 and 8.

In other words, the sterilizing devices 2 are provided only in the edge area where one end of the gap 35 in the longitudinal direction is located, which can reduce the number of sterilizing devices 2, which is advantageous in saving cost.

In some exemplary embodiments, the number of sterilization devices 2 is two, and two sterilization devices 2 are disposed in the edge area where both ends of the length direction of the gap 35 are located, as shown in fig. 9.
