[0030] Explanation of the reference numerals in the drawings:

[0031]

[0032] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the drawings. Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0036] In the prior art, when the air conditioner is in the working state, the air flow flowing in from the air inlet needs to pass through the heat exchange component for heat exchange, which causes the air flow blown out from the air outlet to be heat-exchanged. This results in the temperature of the air flow blown out by the air conditioner being relatively lower than the room temperature and the humidity content being relatively higher. When the human skin feels the cold air of the air conditioner, compared with the natural wind with lower humidity, it will feel more uncomfortable.

[0037] There are various reasons why the airflow with a relatively high humidity blowing onto the human body surface makes people feel uncomfortable. First of all, the humidity of the hot exchange air passing through the air conditioner is high. When it blows onto the skin of the human body surface, the moisture on the skin surface is not easily dissipated, but is directly discharged out of the body in the form of slight sweat. Further, due to the high air humidity, these slight sweat on the body surface is also difficult to evaporate. And the function of sweat itself is to discharge various ions in the body together. The airflow with a relatively high humidity affects this process. Moreover, the slight sweat that cannot evaporate for a long time mixes with the dust in the air, which will make the human body feel sticky. Further, the air humidity is relatively high, and the water molecules in it are also easy to combine with various dusts. Countless water molecules mixed with various dusts impact on the body surface, exacerbating the sticky feeling of the body.

[0038] After the air conditioner has cooled the room temperature to the preset temperature, the air conditioner continues to blow out the airflow after passing through the heat exchanger, that is, the airflow blowing towards the human body when refrigeration is not required is still the airflow with a relatively high humidity, resulting in great discomfort for the user's body feeling. That is, the existing air conditioners are prone to cause discomfort for the user's body feeling. Or, when the temperature reaches the room temperature, some air conditioners are additionally designed with devices for heating and dehumidifying the airflow after heat exchange at the air outlet. Such a design has complex steps, greatly increasing the manufacturing cost and volume of the air conditioner.

[0039] Specifically, in the air conditioner indoor unit, the outside airflow is attracted by the fan, flows into the housing from the air inlet, and after passing through the heat exchange assembly, flows out from the air outlet. And for the existing air conditioner indoor units, especially the air conditioner indoor units with a V-shaped radiator assembly. There is no gap between its first radiator and second radiator. Further, in the prior art, sponges are also pasted at the joint of the first radiator and the second radiator to prevent air leakage, which will result in a dead air zone downstream of the joint, that is, an area where no airflow passes. In addition, when the air conditioner does not need to refrigerate, since there is no gap between the first radiator and the second radiator, at this time, the cold and hot airflow flowing in from the air outlet needs to pass through the radiator assembly for heat exchange. This will result in the problem that the heat exchange air blown out by the air conditioner still has a relatively high humidity at this time, causing discomfort for the user's body feeling.

[0040] Please refer to Figures 1 to 4 , Figure 1 , Figure 3Cross-sectional views of the air conditioner indoor unit with the gap opened and closed, respectively. To solve the above problems, the present invention provides an air conditioner indoor unit 10, which includes a housing 11, a heat exchange component 12, a fan 15, and a switching device. The housing 11 is provided with an air inlet 11a and an air outlet 11b, and an accommodation cavity is provided inside the housing 11. The heat exchange component 12 is disposed in the accommodation cavity. The heat exchange component 12 includes a first heat exchanger 121 and a second heat exchanger 122, and there is a gap between the first heat exchanger 121 and the second heat exchanger 122. The fan 15 is disposed in the housing 11, and the fan 15 is used to suck air flow to flow into the accommodation cavity from the air inlet 11a, pass through the heat exchange component 12, and then flow out from the air outlet 11b. The switching device includes a driving component 14 and a shielding member 13, and the driving component 14 is used to drive the shielding member 13 to open and close the gap. In particular, the air conditioner indoor unit 10 proposed by the present invention and an air conditioner using the air conditioner indoor unit 10 have a natural wind mode. We conduct a wind field simulation analysis, and the air volume flowing through the middle region is relatively large, and when the gap is opened, the wind resistance at the gap is relatively small. Specifically, when the air conditioner cools or heats to a preset temperature, the switching device can be controlled to make the driving component 14 drive the shielding member 13 to open the gap. The wind resistance at the gap is very small. Thus, most of the air flow flowing in from the air inlet 11a will pass through the gap. A small part flows through the first heat exchanger 121 and the second heat exchanger 122.

[0041] Furthermore, there is a mixing region between the heat exchange component 12 and the air outlet 11b. The air flow flowing through the gap and the air flow flowing through the first heat exchanger 121 and the second heat exchanger 122 are mixed evenly here and then flow out from the air outlet 11b. At this time, most of the air blown out from the air outlet 11b is natural wind. Compared with the heat exchange air that has all passed through the first heat exchanger 121 and the second heat exchanger 122, its temperature is higher and its humidity is lower. When it blows on the human body, the body feeling is more comfortable. When the room temperature reaches the preset temperature, if the gap is not closed, when the air flow that has undergone heat exchange through the heat exchange component 12 flows out from the air outlet 11b, its humidity is relatively high. Blowing on people will make people feel uncomfortable.

[0042] In addition, when the gap is opened, the natural wind passing through the gap and the heat exchange wind passing through the first heat exchanger 121 and the second heat exchanger 122 are mixed in the original dead air zone, that is, the area where there is no air flow in the open state. Such a setting will not affect the original wind field design. When the driving component 14 drives the shielding member 13 to open the gap, at this time, the shielding member 13 plays the same role as the sponge in the prior art. That is, it seals the joint of the first heat exchanger 121 and the second heat exchanger 122. At this time, after the air flow in the housing 11 passes through the heat exchange of the first heat exchanger 121 and the second heat exchanger 122, it flows out from the air outlet 11b. The flow direction of the air flow is the same as that in the prior art when the joint of the first heat exchanger 121 and the second heat exchanger 122 is blocked by a sponge. There is no need to separately design the wind field again.

[0043] All in all, the present invention solves the problem that the air conditioner in the prior art easily causes discomfort to the user's body feeling without affecting the original wind field design of the air conditioner indoor unit 10. At the same time, compared with separately designing heating and dehumidifying equipment, the structure of the air conditioner indoor unit 10 in the present application is relatively simplified, and can greatly reduce the manufacturing cost of the air conditioner on the premise of solving the discomfort of the user's body feeling.

[0044] Please refer to Figure 1 , in an optional embodiment, the heat exchange component 12 is located between the blower 15 and the air outlet 11b, and the shielding member 13 is located between the heat exchange component 12 and the air outlet 11b. Thus, when the shielding member 13 is closed, the air flow flowing in from the air inlet 11a can fully exchange heat with the heat exchange component 12 to complete its refrigeration function. In another optional embodiment, a wind guiding member 161 and a water receiving tray 162 are further arranged between the heat exchange component 12 and the air outlet 11b. The wind guiding member 161 plays a guiding role and is used to guide the mixing of the heat exchange wind and the natural wind when the gap is opened. Optionally, the wind guiding member 161 is a wind guiding foam. The first heat exchanger 121 is in contact with the wind guiding member 161, and the second heat exchanger 122 is in contact with the water receiving tray 162. Further, the wind guiding member 161 and the water receiving tray 162 are both connected to the inner wall of the housing 11 and are respectively arranged on the upper and lower sides of the inner wall of the housing 11.

[0045] Please refer to Figures 1 to 4, in an alternative embodiment, the driving component 14 is configured to drive the shielding member 13 away from or close to the gap to open or close the gap. Specifically, the first heat exchanger 121 and the second heat exchanger 122 do not contact each other, and the gap is formed therebetween. The first heat exchanger 121 and the second heat exchanger 122 respectively have a first bottom surface and a second bottom surface disposed in the gap. When the shielding member 13 approaches the gap, the shielding member 13 contacts the first bottom surface and the second bottom surface to close the gap. When it is necessary to open the gap, the shielding member 13 moves away from the gap, that is, there is a gap between the shielding member 13 and the first bottom surface and the second bottom surface. This gap is the gap. The included angle between the first bottom surface and the second bottom surface is the same as the included angle between the first heat exchanger 121 and the second heat exchanger 122. In addition, in addition to approaching or moving away, the shielding member 13 can also switch the gap in other forms of movement, such as a hinge type, a rotary type, etc. However, compared with the solution of the shielding member 13 approaching or moving away from the gap, the installation difficulty of these solutions is relatively high, and sometimes it will also have a certain impact on the air outlet effect.

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 7 , in an alternative embodiment, the first heat exchanger 121 and the second heat exchanger 122 are arranged at an included angle, and the distance between the first heat exchanger 121 and the second heat exchanger 122 gradually decreases along the direction close to the air outlet 11b. The gap is located between the ends of the first heat exchanger 121 and the second heat exchanger 122 close to the air outlet 11b, and the shielding member 13 is located between the heat exchange assembly 12 and the air outlet 11b. Such an arrangement can ensure that when the gap is closed, the air flow flowing in from the air inlet 11a can fully contact the first heat exchanger 121 and the second heat exchanger 122, so as to perform sufficient gas exchange. Further, through simulation, the air volume in the middle regions of the first heat exchanger 121 and the second heat exchanger 122 is relatively large. When the gap is closed, there will be a vortex air flow in this sub-region. When the gap is opened, this vortex air flow can disappear, and at the same time, a large amount of air flows out from the gap, and only a small part of the air flows out after heat exchange between the first heat exchanger 121 and the second heat exchanger 122, and the two are mixed. The advantage of the mixed air is that when the gap is closed originally, the temperature of the heat exchange air at the air outlet 11b is relatively large compared with the indoor temperature difference. When the indoor temperature reaches the set temperature, by mixing the heat exchange air, the temperature of the air outlet 11b can be made close to the room temperature, and the humidity of the air at the air outlet 11b is also correspondingly reduced, thereby increasing the comfort of people.

[0047] Please refer to Figure 5 、 Figure 6 、 Figure 8, in an alternative embodiment, the driving assembly 14 includes a first driving assembly 141 and a second driving assembly 142 respectively connected to two ends of the length direction of the shielding member; the driving assembly 14 is installed on the heat exchange assembly 12; alternatively, an air outlet flange 111 is provided outside the air outlet 11b, and the driving assembly 14 is installed on the air outlet flange 111.

[0048] In an alternative embodiment, the air outlet flange 111 is arranged in a frame shape and is provided outside the air outlet. In some cases, the air outlet flange can be used to install components such as air outlet grilles, so a plurality of fixing holes are provided on the air outlet flange 111. Alternatively, the driving assembly 14 is installed on the heat exchange assembly 12. The first driving assembly 141 and the second driving assembly 142 are respectively connected to two ends of the shielding member 13 in the length direction to drive the shielding member 13 to approach or move away from the gap. Further, since the air outlet 11b of the indoor air conditioner 10 is generally relatively long, correspondingly, the length of the gap and the shielding member 13 is also relatively large. Therefore, in addition to the first side plate and the second side plate, the shielding member 13 is also provided with a reinforcing plate connecting the first side plate and the second side plate. Two ends of the shielding member 13 and the first driving assembly 141 and the second driving assembly 142 are locked in the form of pins or screws. Further, the shielding member 13 has a plurality of reinforcing plates arranged at intervals. In an alternative embodiment, the first driving assembly 141 and the second driving assembly 142 are respectively connected to the reinforcing plates at two ends of the shielding member 13. The setting of the reinforcing plate increases the strength of the shielding member 13, making it not easy to bend or deform during use, thus affecting the effect of the shielding member 13 opening and closing the gap.

[0049] In addition, side plates 123 are provided on the left and right sides of the first heat exchanger 121 and the second heat exchanger 122. The function of the side plates 123 is to seal the sides of the first heat exchanger 121 and the second heat exchanger 122, thereby avoiding air leakage. At the same time, in order to install the driving assembly 14, the side plates 123 extend towards the air outlet 11b and are provided with extension parts. The first driving assembly 141 and the second driving assembly 142 can be installed on the heat exchange assembly 12 through the extension parts. In another embodiment, the first driving assembly 141 and the second driving assembly 142 are installed at the flange of the air outlet 11b. At this time, the indoor air conditioner 10 adopts a suspended embedded installation structure. Installing the first driving assembly 141 and the second driving assembly 142 here has the effects of being easy to disassemble and easy to repair.

[0050] Please refer to Figures 9 to 11, in an alternative embodiment, the driving assembly 14 includes a motor 14a, a gear 14b, and a rack 14c. The motor 14a and the gear 14b are fixed to the air outlet flange 111 or the heat exchange assembly 12. The rack 14c connects the shielding member 13 and the gear 14b. The motor 14a is used to drive the gear 14b to rotate, and the gear 14b drives the rack 14c to move, so that the rack 14c drives the shielding member 13 to approach and move away from the gap. The gear 14b - rack 14c transmission is one of the most widely used mechanical transmissions, which is used to transmit the motion and power between any two shafts. At the same time, the gear 14b - rack 14c transmission also has the characteristics of long service life, stable operation, and high reliability. In an alternative embodiment, the motor 14a is fixed to the air outlet flange 111, so that the motor 14a can be conveniently disassembled for maintenance. In another alternative embodiment, the driving assembly 14 is further provided with a protective housing 14d. The protective housing 14d is provided for aesthetic reasons and to prevent the parts of the driving assembly 14 from being damaged. In addition, corresponding to the first driving assembly 141 and the second driving assembly 142, the air - conditioner indoor unit is respectively provided with a set of motor 14a, gear 14b, rack 14c, and protective housing 14d.

[0051] Please refer to Figure 7 , in an alternative embodiment, the shielding member includes a first side plate and a second side plate arranged at an angle. The first side plate is attached to the end of the first heat exchanger 121 close to the air outlet 11b, and the second side plate is attached to the end of the second heat exchanger 122 close to the air outlet 11b. The angle between the first side plate and the second side plate is the first angle, and the angle between the end face of the first heat exchanger 121 close to the air outlet 11b and the end face of the second heat exchanger 122 close to the air outlet 11b is the second angle. The difference between the first angle and the second angle is not more than 5°. During the manufacturing process, the first angle and the second angle may not be exactly the same. However, for a better sealing effect, we need to control the error between the first angle and the second angle not to exceed 5°. In another embodiment, the shielding member 13 can also be in a folded shape or other shapes, as long as it has a first side plate and a second side plate that can contact the first bottom surface and the second bottom surface. Specifically, during the process of the shielding member 13 approaching the gap, at least part of the first side plate and the second side plate respectively contact the first bottom surface and the second bottom surface, and the non - contacting parts are arranged corresponding to the gap, for blocking the air flow flowing out from the gap.

[0052] In an alternative embodiment, a seal is attached to the surface of the first side plate that is in contact with the first heat exchanger 121, and a seal is attached to the surface of the second side plate that is in contact with the second heat exchanger 122. Specifically, the shielding member 13 with the seal attached has a better shielding effect. When the gap is closed, the shielding member 13 with the seal attached can better block the air flow, so that the air flow needs to pass through the first heat exchanger 121 and the second heat exchanger 122 and then flow out from the air outlet 11b. Further, the seal can be a flexible member with good sealing effect such as silica gel or sponge. In addition, due to processing errors during installation and manufacturing, there may be a certain gap between the first angle and the second angle. The presence of the seal can enable the first side plate and the second side plate with the seal attached to fit well with both sides of the gap when the error between the first angle and the second angle is not large, so as to achieve the effect of closing the gap.

[0053] In an alternative embodiment, the air conditioner indoor unit 10 is a ducted air conditioner indoor unit, and the fan 15 is a centrifugal fan. Specifically, according to the principle of converting kinetic energy into potential energy, a centrifugal impeller accelerates the gas by using a high-speed rotating impeller, and then decelerates and changes the flow direction to convert kinetic energy into potential energy (pressure). The impeller motor is a relatively common driving device with advantages such as easy replacement and maintenance. At the same time, since the centrifugal impeller is relatively common, it is convenient to perform a wind field analysis on it, so as to set the layout of the first heat exchanger 121, the second heat exchanger 122, and the gap in the housing. In addition to the fan 15 composed of the centrifugal impeller and the impeller motor, the air conditioner indoor unit 10 can also adopt other common forms of fans 15, such as an axial flow fan 15, etc., as long as the effect of making the air flow in from the air inlet 11a, pass through the heat exchange assembly 12, and flow out from the air outlet 11b is achieved.

[0054] The present invention also provides an air conditioner, which includes the above-mentioned air conditioner indoor unit 10. Further, the specific structure of the air conditioner indoor unit 10 refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of the above-mentioned embodiments, it at least has the beneficial effects brought by the technical solutions of the above-mentioned embodiments. Specifically, the air conditioner adopting the above technical solution has a cooling mode and a natural wind mode. When the air conditioner operates to make the indoor temperature reach the preset temperature, it can be switched to the natural wind mode through user operation or automatic control. That is, the gap is opened through the driving assembly, so that most of the air flow does not pass through the heat exchange of the heat exchange assembly, but directly flows out from the gap. These air flows are mixed with the air flows that have passed through the first heat exchanger and the second heat exchanger and are discharged from the air outlet. At this time, most of the air flow discharged from the air outlet has not passed through heat exchange and has a lower humidity, and the user's body feeling is comfortable.

[0055] The above are only alternative embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
