For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Next, reference is made to Figures 1 - 11 Describe an air conditioner indoor unit 100 according to an embodiment of the present invention, where the air conditioner indoor unit 100 can cool / heat the indoor environment.

[0038] As Figures 1 - 11As shown, the air conditioner indoor unit 100 according to an embodiment of the present invention includes: a housing 1, a chassis 2, and a positive and negative ion generator 3. An air outlet is provided on the housing 1. The chassis 2 is disposed on the housing 1. The chassis 2 includes an air duct member 20, and an air duct space communicating with the air outlet is provided in the air duct member 20. The positive and negative ion generator 3 includes a generator body 30 and at least one group of probe sets 31. Each group of probe sets 31 includes a positive ion probe 310 and a negative ion probe 311. The positive ion probe 310 and the negative ion probe 311 are respectively connected to the generator body 30 through probe connection lines. The positive ion probe 310 and the negative ion probe 311 are respectively disposed on the inner wall of the air duct space. The generator body 30 is disposed on the chassis 2 and is located outside the air duct member 20.

[0039] Specifically, the air conditioner indoor unit 100 further includes components such as a wind wheel. The wind wheel is rotatably disposed in the air duct space. An air inlet is provided on the housing 1. When the wind wheel rotates, air enters the air duct space from the air inlet, and the air duct space guides the air after heat exchange to the air outlet.

[0040] The air conditioner indoor unit 100 may further include an electric control device. The generator body 30 may be connected to the electric control device to control its working state by the electric control device. The positive ion probe 310 and the negative ion probe 311 are disposed in the air duct space. Specifically, through holes 201 are provided on the inner wall of the air duct space. The positive ion probe 310 and the negative ion probe 311 are respectively inserted into the through holes 201 so that the probe ends of the positive ion probe 310 and the negative ion probe 311 are located in the air duct space. The probe connection lines are electrically connected to the parts of the positive ion probe 310 and the negative ion probe 311 located outside the air duct space, thereby facilitating the laying of the probe connection lines on the outer surface of the air duct member 20.

[0041] When the positive and negative ion generator 3 works, the positive electrode and the negative electrode of the generator body 30 discharge at high voltage through the positive ion probe 310 and the negative ion probe 311 to ionize water molecules in the air, generating a large number of positive and negative ion groups, and releasing the positive and negative ions into the air through the air outlet. The positive and negative ions in the air undergo a chemical reaction to produce active substances, surround and completely decompose microorganisms such as bacteria, molds, and fungi in the air, achieving the effect of sterilization, and the sterilization efficiency can be as high as more than 90%. At the same time, the generated strongly oxidizing substances oxidize and decompose the odor substances in the air, playing a role in removing odors, especially during use, no secondary pollution is generated.

[0042] It should be noted that the positive ion probe 310 and the negative ion probe 311 can be disposed at any position on the inner wall of the air duct member 20, for example, disposed at the upper part of the air duct space (as Figure 2 shown), at the position near the air outlet end of the side wall of the air duct space (as Figure 3 shown), at the position near the air inlet end of the side wall of the air duct space (as Figure 4as shown), the bottom wall of the air duct space (such as Figure 5 shown). It can be understood that when there are multiple probe groups 31, the multiple probe groups 31 can be arranged on the same side wall or different side walls of the air duct member 20, which can be limited according to the actual use situation. Preferably, the probe group 31 is arranged in the middle of the air duct space, so that the positive and negative ions can be effectively released into the air by using the air flow blown out from the air duct space.

[0043] In some related art, some air conditioner indoor units also use positive and negative ion generators to sterilize the air. However, the entire structure of the positive and negative ion generators is arranged inside the air duct member, which not only makes installation inconvenient and the wiring complex, but also easily affects the air output of the air conditioner indoor unit and reduces the refrigeration / heating effect of the air conditioner indoor unit.

[0044] For the air conditioner indoor unit 100 according to the embodiment of the present invention, by setting the positive and negative ion generator 3, the positive ion probe 310 and the negative ion probe 311 are used to discharge at high voltage to ionize the water molecules in the air, generating a large number of positive and negative ion groups, and the positive and negative ions are released into the air through the air outlet. The positive and negative ions in the air undergo a chemical reaction to generate active substances, which surround and completely decompose microorganisms such as bacteria, molds and fungi in the air, realizing the sterilization effect. At the same time, the generated strong oxidizing substances oxidize and decompose the odor substances in the air, playing a role in removing odors and not generating secondary pollution. At the same time, by arranging the generator body 30 on the chassis 2 and outside the air duct member 20, it not only does not affect the air output of the air duct space, but also facilitates the wiring of the probe connection wires, facilitates the installation of the positive and negative ion generator 3, and improves the installation efficiency.

[0045] The inventor has found through a large number of experiments that the distance between the positive ion probe 310 and the negative ion probe 311 in each probe group 31 will affect the sterilization effect of the positive and negative ion generator 3. When the distance is too close, the sterilization effect is not ideal. Through a large number of experimental studies, the inventor surprisingly finds that when the distance between the positive ion probe 310 and the negative ion probe 311 in each probe group 31 is not less than 15 mm, the sterilization efficiency can reach more than 90%, ensuring that the positive and negative ion generator 3 exerts its optimal sterilization effect. Specifically, the value range of the distance between the positive ion probe 310 and the negative ion probe 311 in each probe group 31 is 15 mm - 30 mm. Preferably, the value range of the distance between the positive ion probe 310 and the negative ion probe 311 in each probe group 31 is 18 mm - 20 mm.

[0046] In some embodiments of the present invention, such as Figures 2 - 5As shown, the chassis 2 further includes a wire routing portion 21 provided on at least one side of the air duct member 20. A wire routing space 211 is defined within the wire routing portion 21, and the generator body 30 is provided on the wire routing portion 21. It should be noted that the air conditioner indoor unit 100 and the air conditioner outdoor unit are connected by an internal and external connection wire. The internal and external connection wire connected to the air conditioner indoor unit 100 extends out of the air conditioner indoor unit 100 through the wire routing space 211 and is then connected to the air conditioner outdoor unit. Thus, by providing the generator body 30 on the wire routing portion 21 and utilizing the space beside the air duct member 20 to install the generator body 30, the space utilization rate of the chassis 2 is improved.

[0047] Further, as Figure 6 and Figure 7 shown, the wire routing portion 21 includes a first portion 212 and a second portion 213. The first end of the first portion 212 is connected to the air duct member 20, and the second portion 213 is connected to the second end of the first portion 212. An included angle is formed between the first portion 212 and the second portion 213. For example, as Figure 6 and Figure 7 shown, the first portion 212 and the second portion 213 are perpendicularly arranged. The second portion 213 is provided on other parts of the chassis 2. The generator body 30 is provided on the first portion 212 and / or the second portion 213, so that the structure of the wire routing portion 21 is simple. Optionally, the first portion 212 can be snap-fitted with the air duct member 20, and the second portion 213 can be snap-fitted with other parts of the chassis 2, thus facilitating the assembly of the wire routing portion 21. Of course, it can be understood that the wire routing portion 21 can also be integrally formed with the remaining part of the chassis 2. In a specific example of the present invention, the side wall of the second portion 213 can be formed into a rat-proof structure to protect the internal and external connection wires.

[0048] As Figure 6 and Figure 7 shown, in some embodiments of the present invention, the chassis 2 is provided with a support protrusion 22 and a screw post 23, and the generator body 30 is provided with a screw hole 301. The generator body 30 is placed on the support protrusion 22, and the screw passes through the screw hole 301 and is fixed in the screw post 23. Thus, the support protrusion 22 can support the generator body 30, preventing the generator body 30 from being in a suspended state when it is fixed to the chassis 2 by screws, and further protecting the generator body 30. In some specific examples of the present invention, as Figure 7 shown, the support protrusion 22 is formed into a hollow ring structure, thus saving materials and reducing costs. As Figure 7 shown, optionally, both the screw post 23 and the support protrusion 22 are provided on the first portion 212, so that the generator body 30 is closer to the air duct space, reducing the length of the probe connection wire.

[0049] As Figures 9 - 11As shown, in some embodiments of the present invention, each probe group 31 includes a fixed bracket 312, the fixed bracket 312 is installed on the chassis 2, and the positive ion probe 310 and the negative ion probe 311 of each probe group 31 are provided on the fixed bracket 312. Thus, by providing the fixed bracket 312, the positive ion probe 310 and the negative ion probe 311 are first installed on the fixed bracket 312, and then the fixed bracket 312 is assembled to the air duct member 20, which can facilitate the installation of the probe group 31 and can facilitate setting the distance between the positive ion probe 310 and the negative ion probe 311 of each probe group 31. Further, two insertion holes 3120 are provided on the fixed bracket 312, and the positive ion probe 310 and the negative ion probe 311 respectively extend into the corresponding insertion holes 3120. This facilitates the installation of the positive ion probe 310 and the negative ion probe 311. Of course, it can be understood that the positive ion probe 310 and the negative ion probe 311 can also be installed in other ways, such as by gluing or the like.

[0050] As Figure 2 shown, in some embodiments of the present invention, an assembly groove 202 is provided on the chassis 2, the fixed bracket 312 is an elastic deformation member, the fixed bracket 312 is extruded to be assembled into the assembly groove 202, and the fixed bracket 312 and the assembly groove 202 are in interference fit. That is to say, when installing the fixed bracket 312, the fixed bracket 312 is first extruded to make the fixed bracket 312 deformed so as to facilitate the assembly of the fixed bracket 312 into the assembly groove 202, and then the fixed bracket 312 is released, and the fixed bracket 312 resumes its shape so that an interference fit can be achieved between the fixed bracket 312 and the assembly groove 202, thereby making the assembly method between the fixed bracket 312 and the chassis 2 simple and reliable.

[0051] As Figures 9 - 11 shown, the fixed bracket 312 includes a first plate body 3121 and a second plate body 3122 connected to each other, there is an included angle between the first plate body 3121 and the second plate body 3122, and the insertion hole 3120 is provided on the first plate body 3121, which facilitates the elastic deformation of the fixed bracket 312. Further, a support rib 3123 is provided on the second plate body 3122, and the support rib 3123 supports in the assembly groove 202. Thus, by using the contact between the support rib 3123 and the inner surface of the assembly groove 202, the contact area between the fixed bracket 312 and the assembly groove 202 can be reduced, and it can be avoided that the fixed bracket 312 and the assembly groove 202 cannot be assembled due to interference problems caused by the processing errors of the fixed bracket 312 or the assembly groove 202, ensuring the installation reliability of the fixed bracket 312.

[0052] As Figure 8As shown, in some embodiments of the present invention, a wire groove is provided on the chassis 2, and the probe connecting wire is arranged in the wire groove. Thus, by providing the wire groove, it is convenient to lay the probe connecting wire and avoid interference between the probe connecting wire and other components. In some specific embodiments of the present invention, such as Figure 5 and Figure 8 shown, a plurality of spaced wire clamping buckles 24 are provided on the chassis 2, and a wire groove is defined between the wire clamping buckles 24 and the chassis 2. Thus, the formation method of the wire groove is simple and reliable. Of course, it can be understood that a groove can also be provided on the chassis 2 along the laying path to define the wire groove.

[0053] In some specific examples of the present invention, such as Figure 8 shown, a part of the chassis 2 is separated from the rest and bent to define the wire clamping buckle 24, so that the processing method of the wire clamping buckle 24 is simple. Of course, it can be understood that the wire clamping buckle 24 can also be formed by other methods, such as snap-fitting a separately formed wire clamping buckle 24 on the chassis 2.

[0054] In some embodiments of the present invention, a filter screen is provided at the air inlet to achieve a filtering effect, and the air conditioner indoor unit 100 further includes a negative ion sterilization device provided at the air inlet and / or the air outlet to sterilize the air.

[0055] In some embodiments of the present invention, the air conditioner indoor unit 100 further has a high-temperature sterilization function. When the high-temperature sterilization function is turned on, the temperature of the indoor heat exchanger provided in the casing 1 and / or a separately provided heating element can be used for sterilization.

[0056] In some embodiments of the invention, such as Figure 1 shown, the air conditioner indoor unit 100 further includes a first air deflector 4. The first air deflector 4 is rotatably arranged on the air duct member 20 and extends along the length direction of the air duct member 20. Thus, by providing the first air deflector 4, the air outlet direction of the air outlet can be changed, and the use comfort of the air conditioner indoor unit 100 can be improved. Further, a plurality of first micropores 40 are provided on the first air deflector 4. Thus, when the first air deflector 4 closes the air outlet end of the air duct space or the first air deflector 4 rotates to form an angle with the air outlet direction of the air outlet end of the air duct space, air can be blown out from the plurality of first micropores 40, and the plurality of first micropores 40 can disperse the air, so that a draft-free effect can be achieved and the use comfort can be improved.

[0057] Specifically, the air conditioner indoor unit 100 further includes a first driver for driving the first air deflector 4 to rotate, and the first driver and the generator body 30 can be arranged at the same end of the air outlet.

[0058] Such as Figure 1As shown, according to some embodiments of the present invention, the air conditioner indoor unit 100 further includes a second air deflector 5. The second air deflector 5 is rotatably provided on the housing 1 and extends along the length direction of the air outlet. Thus, the air outlet direction of the air outlet can be changed, improving the use comfort of the air conditioner indoor unit 100. Specifically, the air conditioner indoor unit 100 further includes a second driver for driving the second air deflector 5 to rotate. The second driver and the generator body 30 can be provided at the same end of the air outlet.

[0059] Furthermore, a plurality of second micro-holes are provided on the second air deflector 5. Thus, by providing a plurality of second micro-holes, when the second air deflector 5 closes the air outlet or the second air deflector 5 rotates to form an angle with the air outlet direction of the air outlet, air can be blown out from the plurality of second micro-holes. The plurality of second micro-holes can disperse the air, thereby achieving a draft-free effect and improving the use comfort.
