Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor unit of an air conditioner. Background Technology

[0002] The ion wind mode of existing air conditioners generally involves opening the air deflector to blow out the ions generated by the ion generator inside the air outlet. This results in the ions being blown out in a concentrated manner rather than being dispersed. Furthermore, since the ion wind mode needs to be kept on for a long time, the air deflector needs to be kept open, which not only makes the air conditioner less aesthetically pleasing when it is working, but also causes discomfort to the user due to the air deflector being open for a long time. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of the present invention is to provide an indoor unit for an air conditioner that not only allows the emitted ions to be more dispersed, but also avoids the unnecessary continuous opening of the air guide vane.

[0004] To achieve the above objectives, an indoor unit of an air conditioner is provided according to an embodiment of the present invention, comprising: a casing, wherein an air inlet and an air outlet are provided on the casing; an indoor heat exchanger disposed within the casing; and an indoor fan, wherein an air duct component is disposed within the casing, the indoor fan being disposed at the air inlet end of the air duct component, and the air outlet end of the air duct component being connected to the air outlet. The indoor fan is used to introduce airflow from outside the casing into the casing through the air inlet, and after heat exchange by the indoor heat exchanger, the airflow exits from the casing. The air outlet outputs air outwards; characterized in that it further includes: an air guide plate, wherein the air outlet is at least partially located on the lower side of the housing, the air guide plate is rotatably disposed on the lower side of the housing and selectively opens and closes the air outlet on the lower side of the housing; wherein it further includes: an ion emitter, wherein the ion emitter is disposed within the air duct and adjacent to the air outlet end of the air duct, and an ion air hole is formed on the lower side of the housing in the portion corresponding to the ion emitter and the air guide plate, the ion air hole being connected to the interior of the air duct.

[0005] According to the embodiment of the present invention, the indoor unit of the air conditioner, by setting the ion emitter inside the air duct and adjacent to the air outlet of the air duct, can ensure that the ions emitted by the ion emitter are fully mixed with the air in the air duct before flowing to the outside, and the ions will be more dispersed. In addition, since the ion air hole is set on the lower side of the casing and located between the ion emitter and the air guide plate, after the indoor fan is working, the ions can be blown out with the air in the air duct, without the need to open the air guide plate before the ions can be released, making the structure simpler.

[0006] According to some embodiments of this utility model, in the air outlet direction, the cross-sectional area of ​​the ion air hole first gradually decreases and then gradually increases.

[0007] The above technical solution has the following advantages or beneficial effects: the ion air hole has a certain length in the air outlet direction, and the cross-sectional area of ​​the air inlet end of the ion air hole is set to be large, so that more ion-containing air enters the ion air hole per unit time. In the air outlet direction, the cross-sectional area of ​​the ion air hole gradually decreases, which can increase the flow velocity of the ion-containing air in the ion air hole, thereby improving the air outlet efficiency. Furthermore, after the cross-sectional area of ​​the ion air hole gradually decreases, the cross-sectional area of ​​the ion air hole gradually increases again, which can increase the final air outlet range of the ion air hole, thereby improving the uniformity of the distribution of ion-containing air.

[0008] According to some embodiments of this utility model, the ion air holes are arranged to extend in the left-right direction of the housing.

[0009] The above technical solution has the following advantages or beneficial effects: The casing extends horizontally along its length, and the ion air vents are also extended horizontally along the casing. This not only maximizes the area of ​​the ion air vents, thereby improving the airflow efficiency containing ions, but also allows for a larger airflow range, further enhancing the uniformity of ion-containing airflow distribution. According to some embodiments of the present invention, at least one partition plate spaced apart in the front-to-back direction is provided inside the ion air hole to divide the ion air hole into multiple sub-ion air holes.

[0010] The above technical solution has the following advantages or beneficial effects: by setting at least one baffle that is spaced apart from each other in the front and back directions inside the ion air hole, the ion air hole is divided into multiple sub-ion air holes, which can further increase the flow velocity of the ion-containing air in the ion air hole. According to some embodiments of this utility model, each of the sub-ion air holes is provided with multiple reinforcing ribs spaced apart in the left and right directions.

[0011] The above technical solution has the following advantages or beneficial effects: by setting multiple reinforcing ribs spaced apart in the left and right directions in each ion outlet, not only can the structural strength of the partition be improved, thereby improving the air outlet stability of the ion outlet, but also a smaller air outlet containing ions can be defined between two adjacent reinforcing ribs, which can further improve the air outlet efficiency of the ion-containing air.

[0012] According to some embodiments of this utility model, the reinforcing ribs in two adjacent sub-ion air holes are arranged in an alternating manner.

[0013] The above technical solution has the following advantages or beneficial effects: by staggering the reinforcing ribs in adjacent ion air holes, not only can the structural strength of multiple partitions be further improved, but the overall airflow from the ion air holes can also be made more uniform. According to some embodiments of the present invention, the air inlet side of the ion air hole is flush with the air duct inside the air duct component.

[0014] The above technical solution has the following advantages or beneficial effects: by aligning the air inlet side of the ion air hole with the air duct inside the air duct component, the opening of the ion air hole can be made to conform to the airflow direction inside the air duct component. This not only prevents the opening of the ion air hole from changing the airflow direction inside the air duct component and reducing the air outlet efficiency, but also reduces the noise of air flowing into the ion air hole.

[0015] According to some embodiments of this utility model, the air outlet side of the ion air hole is flush with the lower side of the housing.

[0016] The above technical solution has the following advantages or beneficial effects: by aligning the air outlet side of the ion air hole with the lower side of the casing, it can not only prevent the air outlet side of the ion air hole from being recessed inward relative to the lower side of the casing, thus preventing the airflow containing ions from being obstructed by the lower side of the casing after the air flows out of the ion air hole, but also prevent the air outlet side of the ion air hole from bulging outward relative to the lower side of the casing, thus affecting the arrangement of the indoor unit of the air conditioner.

[0017] According to some embodiments of this utility model, the ion emitter corresponds to the middle part of the ion wind hole in the left-right direction.

[0018] The above technical solution has the following advantages or beneficial effects: it can prevent uneven distribution of ions in the air duct component, improve the uniformity of ion distribution of ions emitted by the ion emitter in the air duct component, and thus further improve the ion emission effect of the ion emitter.

[0019] According to some embodiments of the present invention, a decorative panel is provided on the lower side of the housing, the decorative panel is located behind the air guide plate, and the ion air holes are opened at the front end of the decorative panel adjacent to the air guide plate.

[0020] The above technical solution has the following advantages or beneficial effects: A decorative panel is provided on the lower side of the casing, which can seal the lower side of the casing. The decorative panel is located behind the air guide plate. Therefore, the ion air hole can be directly opened at the front end of the decorative panel adjacent to the air guide plate, which can meet the air outlet position requirements of the ion air hole. In this way, by making full use of the space of the decorative panel to arrange the ion air hole, there is no need to set up a separate component to open the ion air hole, which can simplify the structural design of the indoor unit of the air conditioner.

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

[0026] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0027] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0028] The following is based on Figures 1-9 This invention describes an embodiment of an air conditioner indoor unit 100.

[0029] According to the embodiments of the present invention, the indoor unit 100 of the air conditioner is part of the air conditioner, which includes the outdoor unit and the indoor unit 100 of the air conditioner of the present invention. The air conditioner includes a refrigerant circulation loop, an indoor fan 30, an outdoor fan, a power consumption sensor, and a controller.

[0030] In an embodiment of this utility model, the refrigerant circulation loop of the air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator. The refrigerant circulates between the compressor, condenser, expansion valve, and evaporator, thus forming a refrigerant circulation loop. The compressor is located in the outdoor unit of the air conditioner. One of the condenser and evaporator is an outdoor heat exchanger, and the other is an indoor heat exchanger 20. The outdoor heat exchanger is located in the outdoor unit of the air conditioner, and the indoor heat exchanger 20 is located in the indoor unit 100 of the air conditioner.

[0031] Furthermore, the compressor can compress the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant. This heat can be exchanged with indoor air to heat the indoor air, or with outdoor air to cool the indoor air. In addition, the compressor can provide power for the circulation of the refrigerant.

[0032] When the refrigerant enters the outdoor heat exchanger, it exchanges heat with the outdoor air. When the refrigerant enters the indoor heat exchanger 20, it exchanges heat with the indoor air.

[0033] When the air conditioner is in cooling mode, heat is transferred from the refrigerant to the outdoor air in the outdoor heat exchanger, and heat is transferred from the indoor air to the refrigerant in the indoor heat exchanger 20. This allows the refrigerant to dissipate indoor heat to the outdoor environment, thereby lowering the indoor temperature.

[0034] When the air conditioner is in heating mode, heat is transferred from the outdoor air to the refrigerant in the outdoor heat exchanger, and heat is transferred from the refrigerant to the indoor air in the indoor heat exchanger 20. This allows the refrigerant to absorb heat from the outdoor environment and transfer the heat to the indoor environment, thereby raising the indoor temperature.

[0035] An expansion valve can change the pressure of the refrigerant in the refrigerant circulation loop. By throttling and reducing pressure, the expansion valve converts the medium-temperature, high-pressure liquid refrigerant into low-temperature, low-pressure wet vapor, which then absorbs heat in the evaporator to achieve a cooling effect.

[0036] Furthermore, the expansion valve can automatically adjust the flow rate based on the superheat of the gaseous refrigerant at the evaporator outlet, maintaining a stable indoor temperature and meeting the requirements of refrigerant circulation. More importantly, the expansion valve can prevent liquid refrigerant from entering the compressor, avoiding liquid hammer and protecting the compressor from damage.

[0037] The indoor fan 30 is used to drive indoor air through the indoor heat exchanger 20 by rotation, so that the refrigerant and the indoor air can exchange heat. Under the action of the indoor fan 30, the flow of indoor air to the indoor heat exchanger 20 can be accelerated, thereby accelerating the heat exchange between the indoor air and the refrigerant.

[0038] Outdoor fans are used to rotate and draw outdoor air through an outdoor heat exchanger, enabling heat exchange between the refrigerant and the outdoor air. The outdoor fan accelerates the flow of outdoor air to the outdoor heat exchanger, thereby speeding up the heat exchange between the outdoor air and the refrigerant.

[0039] In addition, the indoor unit of the air conditioner is provided with an air duct component 13, and an indoor fan 30 is provided at the air inlet end of the air duct component 13. The air outlet end of the indoor fan 30 is connected to the air outlet 12 on the casing 10. The air inlet 11 of the casing 10 is located on the upper side of the casing 10. The indoor heat exchanger 20 is provided between the air inlet 11 and the indoor fan 30. The indoor fan 30 is used to introduce the airflow outside the casing 10 into the casing 10 through the air inlet 11, and after heat exchange by the indoor heat exchanger 20, it is output to the outside through the air outlet 12.

[0040] Furthermore, the air duct component 13 is arc-shaped, and part of the air outlet 12 of the air duct component 13 is located at the front end of the lower side of the housing 10, and the other part is located at the lower end of the front side of the housing 10. In some embodiments of this utility model, a panel 18 that can be raised and lowered is provided on the front side of the housing 10. When the panel 18 rises, it opens part of the air outlet 12 at the lower end of the front side of the housing 10.

[0041] Combination Figure 1-9 As shown, the air outlet 12 at the front end of the lower side of the housing 10 is provided with a rotatable air guide plate 14. The air guide plate 14 can adjust the air outlet direction of the entire air outlet 12 by rotating to open and close the air outlet 12 at the front end of the lower side of the housing 10.

[0042] In some embodiments of this utility model, an ion emitter 15 is provided on the lower side of the portion of the air duct 13 adjacent to the air outlet end of the air duct 13, and the ion emitter 15 can selectively emit ions.

[0043] During normal operation of the indoor unit 100 of the air conditioner, since the ion emitter 15 is located at the air outlet end of the adjacent air duct component 13, and is not directly located at the air outlet 12, there is still a certain distance between the ion emitter 15 and the air outlet 12.

[0044] After the ion emitter 15 emits ions, the ions will mix thoroughly with the air in the air duct 13 before being blown out from the air outlet 12. This allows the ions to be more dispersed after being blown out from the air outlet 12, and they will not concentrate in one place, thus improving the effect of the ions.

[0045] Furthermore, an ion air hole 16 is provided on the lower side of the housing 10 between the corresponding ion emitter 15 and the air guide plate 14, and the ion air hole 16 is connected to the interior of the air duct component 13.

[0046] The ion air hole 16 is equivalent to adding an air outlet on the lower side of the casing 10 between the ion emitter 15 and the air guide plate 14. Since there is a certain distance between the ion air hole 16 and the ion emitter 15, the ions emitted by the ion emitter are fully mixed with the air in the air duct 13 before flowing out from the ion air hole 16. Under the premise of ensuring uniform ion dispersion, it can avoid the need for the air guide plate 14 to be rotated to open the air outlet 12 on the front side of the lower side of the casing 10 for the ions to be blown out, which makes the operation of the indoor unit 100 of the air conditioner simpler.

[0047] Furthermore, the air deflector 14 does not need to be open for extended periods, thus preventing the air deflector 14 from directing the air in one direction for a long time, which could cause discomfort to users in that direction.

[0048] Therefore, by placing the ion emitter 15 inside the air duct 13 and adjacent to the air outlet of the air duct 13, it can be ensured that the ions emitted by the ion emitter 15 are fully mixed with the air in the air duct 13 before flowing to the outside, and the ions will be more dispersed. In addition, since the ion air hole 16 is located on the lower side of the housing 10 and between the ion emitter 15 and the air guide plate 14, after the indoor fan 30 is working, the ions can be blown out with the air in the air duct 13 without opening the air guide plate 14, and the structure is simpler.

[0049] Combination Figure 5 As shown, in the air outlet direction, the cross-sectional area of ​​the ion air hole 16 first gradually decreases and then gradually increases.

[0050] Specifically, the ion air hole 16 has a certain length in the air outlet direction, and the cross-sectional area of ​​the air inlet end of the ion air hole 16 is set to be large, so that more air containing ions can enter the ion air hole 16 per unit time.

[0051] In the air outlet direction, the cross-sectional area of ​​the ion air hole 16 gradually decreases, which can increase the flow velocity of the air containing ions in the ion air hole 16, thereby improving the air outlet efficiency.

[0052] Furthermore, after the cross-sectional area of ​​the ion air hole 16 gradually decreases, the cross-sectional area of ​​the ion air hole 16 gradually increases again. This can improve the final air outlet range of the ion air hole 16, thereby improving the uniformity of the distribution of air containing ions.

[0053] Combination Figure 7 and Figure 8 As shown, the ion air vents 16 extend in the left and right directions of the housing 10.

[0054] Specifically, the length of the housing 10 extends in the left and right directions, and the ion air holes 16 are extended in the left and right directions of the housing 10. This not only maximizes the area of ​​the ion air holes 16, thereby improving the airflow efficiency of the ion-containing air, but also makes the airflow range of the ion air holes 16 larger, thereby further improving the uniformity of the distribution of the ion-containing air.

[0055] Combination Figure 8 and Figure 9 As shown, at least one partition 161 spaced apart in the front-to-back direction is provided inside the ion air hole 16 to divide the ion air hole 16 into multiple sub-ion air holes 162.

[0056] Specifically, by providing at least one baffle 161 spaced apart in the front and back directions in the ion air hole 16, the ion air hole 16 is divided into multiple sub-ion air holes 162, which can further increase the flow speed of the wind containing ions in the ion air hole 16.

[0057] Combination Figure 8 and Figure 9 As shown, each sub-ion air hole 162 is provided with multiple reinforcing ribs 163 spaced apart in the left and right directions. Specifically, by providing multiple reinforcing ribs 163 spaced apart in the left and right directions in each sub-ion air hole 162, the structural strength of the partition 161 can be improved, thereby improving the air outlet stability of the sub-ion air hole 162.

[0058] Furthermore, a smaller air outlet for ion-containing air can be defined between two adjacent reinforcing ribs 163, which can further improve the air outlet efficiency of ion-containing air.

[0059] Combination Figure 8 and Figure 9 As shown, the reinforcing ribs 163 in two adjacent sub-ion air holes 162 are arranged in an alternating manner.

[0060] Specifically, by staggering the reinforcing ribs 163 in two adjacent sub-ion air holes 162, the structural strength of the multiple partitions 161 can be further improved, and the overall airflow of the ion air holes 16 can be made more uniform.

[0061] Combination Figure 8 and Figure 9 As shown, the air inlet side of the ion air hole 16 is flush with the air duct inside the air duct component 13.

[0062] Specifically, by aligning the air inlet side of the ion air hole 16 with the air duct inside the air duct component 13, the opening of the ion air hole 16 can be made to conform to the airflow direction inside the air duct component 13. This not only prevents the opening of the ion air hole 16 from changing the airflow direction inside the air duct component 13 and reducing the efficiency of air outlet, but also reduces the noise of air flowing into the ion air hole 16.

[0063] Combination Figure 8 and Figure 9 As shown, the air outlet side of the ion air hole 16 is flush with the lower side of the housing 10.

[0064] Specifically, by aligning the air outlet side of the ion air hole 16 with the lower side of the casing 10, it not only prevents the air outlet side of the ion air hole 16 from being recessed inward relative to the lower side of the casing 10, thus preventing the lower side of the casing 10 from obstructing the flow of air containing ions after the air flows out of the ion air hole 16, but also prevents the air outlet side of the ion air hole 16 from protruding outward relative to the lower side of the casing 10, thus affecting the arrangement of the indoor unit 100 of the air conditioner.

[0065] Combination Figure 3 As shown, the ion emitter 15 corresponds to the middle part of the ion vent 16 in the left-right direction.

[0066] Specifically, by positioning the ion emitter 15 in a position corresponding to the center of the ion air hole 16 in the left-right direction, uneven distribution of ions in the air duct 13 can be prevented, and the uniformity of ion distribution emitted by the ion emitter 15 in the air duct 13 can be improved, thereby further enhancing the ion emission effect of the ion emitter 15.

[0067] Combination Figures 4-9 As shown, a decorative panel 17 is provided on the lower side of the housing 10. The decorative panel 17 is located behind the air guide plate 14, and the ion air hole 16 is opened at the front end of the decorative panel 17 adjacent to the air guide plate 14.

[0068] Specifically, a decorative panel 17 is provided on the lower side of the casing 10. The decorative panel 17 can seal the lower side of the casing 10. The decorative panel 17 is located behind the air guide plate 14. Therefore, the ion air hole 16 can be directly opened at the front end of the decorative panel 17 adjacent to the air guide plate 14, which can meet the air outlet position requirements of the ion air hole 16. In this way, by making full use of the space of the decorative panel 17 to arrange the ion air hole 16, there is no need to set up a separate component to open the ion air hole 16, which can simplify the structural design of the indoor unit of the air conditioner.
