Detailed Description

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. 3 to 9, 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. 5. The air deflector 33 may open or close the air outlet 32.

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 air channel in the 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. 3 to 9, the sterilization device 2 is disposed in the housing 3 and located at the gap 35. As shown in fig. 1 and 2, the sterilization device 2 includes a discharge assembly. The discharge assembly includes an emitter 21, a plurality of receiver poles 22, and a plurality of insulators 23. The emitter 21 includes a conductive body 211 and two discharge portions 212. The conductive body 211 has a plate-like structure. The receiving pole 22 may also have 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. The receiving electrodes 22 are disposed on both sides of the conductive body 211 in the width direction. The two receiving poles 22 (i.e. the receiving poles 22 on both sides) are respectively arranged at intervals opposite to the two discharging parts 212 of the emitter 21, and an insulating member 23 is arranged between the discharging parts 212 and the receiving poles 22 which are arranged at intervals opposite to each other, so that dielectric barrier discharge can be generated by the two discharging parts 212 of the emitter 21 to generate sterilizing substances.

Wherein the sterilization device 2 mainly plays a role in sterilization. The sterilization device 2 can generate dielectric barrier discharge under the action of a high-voltage power supply with voltage variation such as a pulse power supply, an alternating current power supply and the like, ionize air through a strong electric field to generate sterilization substances, and the sterilization substances can comprise strong oxidizing substances which can oxidize and decompose bacteria in the air, so that the sterilization effect is achieved. And, the sterilization device 2 comprises an emitter 21, at least two receiving poles 22 and at least two insulators 23. 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. 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 with a receiving electrode 22 opposite thereto, and an insulating member 23 being provided between each discharge portion 212 and the receiving electrode 22. Thus, one emitter 21 can correspond to two 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 purifying and 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 the receiving electrodes 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.

As shown in fig. 5, the sterilizing device 2 is disposed in the casing 3 and located at a gap 35 between the heat exchanger 4 and the wind wheel 5, and in a state that the air outlet 32 of the air conditioner is closed, sterilizing substances (such as strong oxidizing substances) generated by the sterilizing device 2 can be diffused into each corner of the inner cavity of the air conditioner in the casing 3, so as to realize sterilization in the cavity. 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.

Through tests, when the air conditioner provided by the embodiment of the utility model is used for sterilizing the inner cavity of the air conditioner, the sterilizing device 2 adopts 8KV voltage and works for 0.5h, and the surface sterilizing rate of the inner cavity of the air conditioner can reach 99.9%; when the indoor space is sterilized, 7KV voltage is adopted by the sterilizing device 2, the operation is carried out for 1 hour, and the sterilizing rate can reach 98.2%.

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 split air conditioner can be a wall-mounted air conditioner or a floor-mounted air conditioner, can only comprise an air conditioner indoor unit of the split air conditioner, and can also be a complete split air conditioner.

In some exemplary embodiments, as shown in fig. 1 and 2, the sterilization device 2 may further include a mounting frame 1, and the mounting frame 1 may be a frame structure, such as a substantially rectangular parallelepiped shape. The mounting frame 1 is provided with an air flow channel 13, and the air flow channel 13 is communicated with the inner space of the shell 3. 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 bracket 1 provides a mounting carrier for the emitter electrode 21, the receiver electrode 22 and the insulator 23, ensuring its stability and reliability. 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 sterilization device 2 may not include the mounting frame 1, and for example, the emitter 21, the receiver 22 and the insulator 23 may be directly mounted on a corresponding structure (such as the casing 3) of the air conditioner.

In some exemplary embodiments, the receiving pole 22 is also a plate-like structure, and the width direction of the conductive body 211 is perpendicular to the thickness direction of the receiving pole 22, as shown in fig. 1 and 2.

In other words, the emitter 21 and the receiver 22 are plate-shaped structures and are perpendicular to each other. 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, the receiver 22 and the insulator 23 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, the receiver 22, and the insulator 23 may be fixedly coupled to the mounting cap 12 by means of a snap fit, a fastener (e.g., a screw), or the like. The insulator 23 may also be integrally formed with the mounting cap 12. The mounting base 11 and the mounting cover 12 may both be frame structures including hollowed-out portions so as to form the air flow channel 13 in the mounting frame 1.

In one embodiment, as shown in fig. 2, the mounting base 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 base 11. During assembly, the mounting cover 12 is directly covered on the mounting seat 11, and the mounting cover 12 is pressed, so that the buckle can be clamped on the clamping boss, and the assembly mode is simple and quick. 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. The insulator 23 is integrally formed with the mounting cover 12.

Of course, the structural form of the mount 1 is not limited to this, and the mounting positions and fixing modes of the emitter electrode 21, the receiver electrode 22, and the insulator 23 are not limited to this, as long as the emitter electrode 21 and the receiver electrode 22 can be fixed. For example, the insulator 23 may be integrally formed with the receiver 22 and fixed to the receiver 22 as an insulating layer.

In some exemplary embodiments, the insulator 23 has a plate-like structure and is located between the emitter electrode 21 and the receiver electrode 22, as shown in fig. 1 and 2.

As shown in fig. 2, in the width direction of the conductive body 211, a distance d1 between the insulating member 23 and the adjacent receiving pole 22 is in the range of 0mm to 20mm, such as 0mm (i.e., the insulating member 23 is directly attached to the surface of the receiving pole 22), 1mm, 3mm, 5mm, 10mm, 15mm, 20mm, and the like. The distance d2 between the insulating member 23 and the adjacent discharge portion 212 is greater than 0mm and less than or equal to 20mm, such as 1mm, 3mm, 5mm, 10mm, 15mm, 20mm, etc., in the width direction of the conductive body 211.

In this way, the sterilization effect of the sterilization device 2 can be considered, the discharge tip 2121 and the adjacent insulation piece 23 can be prevented from being broken down easily due to too close distance, a sufficient space for air flow to pass through can be ensured between the discharge tip 2121 and the adjacent insulation piece 23, and the volume size of the sterilization device 2 is considered.

Of course, the distance d1 between the insulator 23 and the adjacent receiving electrode 22 and the distance d2 between the insulator 23 and the adjacent discharging portion 212 in the width direction of the conductive body 211 are not limited to the above-described ranges, and may be adjusted as needed.

In other embodiments, the insulator 23 may also be in a cylindrical configuration, enveloping the receiver 22.

In some exemplary embodiments, the discharge assembly includes a plurality of emitters 21, such as two, three, or even more emitters 21, spaced apart in the thickness direction of the conductive body 211 and positioned between two insulators 23. 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.

In some exemplary embodiments, the discharge assembly includes a plurality of emitters 21 spaced apart along the width direction of the conductive body 211, and a receiving electrode 22 is disposed between any adjacent two of the emitters 21 in the width direction of the conductive body 211, and an insulating member 23 is disposed between any adjacent receiving electrode 22 and the emitter 21. The width direction of the conductive body 211 may be identical to the width direction of the sterilization device. Thus, this solution corresponds to the effect that the discharge assembly of the sterilization apparatus 2 achieves array arrangement in the width direction of the sterilization apparatus 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.

In some exemplary embodiments, the heat exchanger 4 includes a plurality of interconnected sub-heat exchangers 41, as shown in FIG. 5, with the plurality of sub-heat exchangers 41 circumscribing a semi-enclosed structure. The wind wheel part is positioned in the semi-surrounding structure, and the sterilizing device is positioned in the semi-surrounding structure.

Such as: as shown in fig. 5, the heat exchanger 4 includes four interconnected sub-heat exchangers 41, and the opening of the semi-enclosed structure surrounded by the four sub-heat exchangers 41 faces the wind wheel and the air outlet. A portion of the rotor is located within the semi-enclosed structure. The gap between the wind wheel and the heat exchanger 4 is also located in the semi-enclosing structure, so that the sterilizing device is also located in the semi-enclosing 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 be identical to the axial direction of the wind wheel.

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.

In some exemplary embodiments, the length of the gap 35 coincides with the length of the heat exchanger 4. In other words, the cross section of the gap 35 extends along the length direction of the heat exchanger 4, and the length direction of the gap 35 also coincides with the axial direction of the wind wheel 5. The sterilizing device 2 is provided in the edge region in the longitudinal direction of the gap 35, as shown in fig. 4, 7 and 8.

The air conditioner is beneficial to reducing the arrangement of the sterilizing device 2, causing wind resistance to the air duct and improving the air outlet efficiency of the air conditioner.

In some exemplary embodiments, as shown in fig. 4 and 7, in the length direction of the heat exchanger 4, a distance k1 between an end of the heat exchanger 4 in the length direction near the sterilizing apparatus 2 and the sterilizing apparatus 2 satisfies: k1 is more than or equal to 0mm and less than or equal to 200mm, such as 0mm, 20mm, 40mm, 50mm, 80mm, 100mm, 120mm, 150mm, 180mm, 200mm and the like.

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. The distance k1 between the end of the heat exchanger 4, which is adjacent to the sterilization device 2 in the longitudinal direction, and the sterilization device 2 may be a distance between the end of the heat exchanger 4, which is adjacent to the emitter 21 in the longitudinal direction, and the emitter 21.

Of course, the distance k1 between the end of the heat exchanger 4 adjacent to the sterilizing device 2 in the longitudinal direction and the sterilizing device 2 is not limited to the above range, and may be adjusted as needed.

In some exemplary embodiments, the number of sterilization devices 2 is one, as shown in fig. 4 and 7.

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. 8.

In other words, the sterilizing device 2 is provided in the edge regions where both ends of the gap 35 in the longitudinal direction are located. The scheme can increase the generation amount of sterilizing substances, is beneficial to uniform sterilization of the inner cavity of the air conditioner, is beneficial to shortening the sterilization time and improves the sterilization efficiency.
