Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air outlet structure, an air conditioner and an anti-condensation control method. Background Art

[0002] At present, for air conditioners with transparent decorative parts on the air outlet, condensation (i.e., condensed water condensation) is prone to occur due to uneven temperature on both sides of the decorative parts. Existing air conditioners are usually equipped with an appearance part above the air outlet (the appearance part can be a windshield for guiding air or a purely decorative appearance panel). When the air conditioner is in cooling mode, the air outlet blows out cold air. The cold airflow hits the inner panel of the appearance part, which absorbs the heat of the inner panel of the appearance part, causing the overall temperature of the appearance part to drop, and then the temperature of the outer panel on the other side of the appearance part is lower. When hot air in the external environment (i.e., air with a temperature higher than that of the outer panel) contacts the outer panel of the appearance part, the moisture in the hot air will condense on the outer panel, i.e., condensation occurs. At this time, the user can clearly see the condensed water on the outer panel of the appearance part, which seriously affects the appearance of the air conditioner and the user experience. In particular, for appearance parts made of transparent materials, the user can more intuitively see the condensation phenomenon, further reducing the user's visual experience and pleasant experience.

[0003] In the prior art, a method of opening multiple through holes on the exterior part is usually adopted to guide the cold air flow at the air outlet to blow to the outer panel surface of the exterior part, so as to adjust the external air temperature at the outer panel surface of the exterior part, thereby solving the condensation problem on the outer panel surface. However, the above scheme has the following problems: the first problem is that due to the presence of a large number of through holes on the outer panel surface of the exterior part, the integrity and aesthetics of the appearance of the exterior part will be seriously damaged, which is not conducive to the overall aesthetics of the air conditioner; the second problem is that when the air flow is blown to the outer panel surface through the through holes, the air flow usually cannot fit tightly to the outer panel surface, resulting in uneven regulation of the external air temperature at the outer panel surface, and the temperature regulation effect is slow, making it difficult to completely eliminate condensation. At the same time, aerodynamic noise may also occur at the through holes. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 5As shown, an embodiment of the present invention provides an air outlet structure, which includes an air outlet portion 10, an appearance component 20 and an anti-condensation structure 30. The air outlet portion 10 has an air outlet cavity 11, the inlet of the air outlet cavity 11 is connected to the air outlet duct 50 of the air conditioner, the inner panel surface 21 of the appearance component 20 faces the air outlet cavity 11, the anti-condensation structure 30 has an auxiliary air duct 31, the auxiliary air duct 31 has an air inlet 311 and an air outlet 312 that are connected to each other, the air inlet 311 and the air outlet duct 50 can be selectively connected or disconnected, and the air outlet 312 faces the outer panel surface 22 of the appearance component 20.

[0035] The present invention adjusts the temperature of the air at the outer panel 22 of the appearance part 20 by setting an auxiliary air duct 31, effectively balancing the temperature difference between the inner panel 21 and the outer panel 22 of the appearance part 20, thereby solving the condensation problem of the appearance part 20 of the air conditioner, and improving the appearance of the air conditioner and the user experience; and by setting the auxiliary air duct 31, it can also effectively adjust the ambient temperature at the outer panel 22 of the appearance part 20 (for example: the indoor temperature at the outer panel 22 of the appearance part 20), effectively solving the problem of uneven ambient temperature regulation of the air conditioner, and reducing the temperature regulation dead corners and blowing dead corners of the air conditioner; at the same time, compared with the prior art method of opening multiple through holes on the appearance part 20, the present invention will not destroy the integrity and aesthetics of the appearance of the appearance part 20, and is more conducive to the overall aesthetics of the air conditioner, and the present invention regulates the external air temperature at the outer panel 22 more evenly, and the temperature regulation effect is fast, effectively avoiding the occurrence of aerodynamic noise.

[0036] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, the auxiliary air duct 31 is divided into two sections, one section near the air inlet 311 is inclined relative to the air outlet duct 50, and the other section near the air outlet 312 is parallel to the air outlet duct 50, and the connection between the two sections is chamfered. This arrangement can effectively reduce the air resistance and aerodynamic noise in the auxiliary air duct 31, and makes the auxiliary air duct 31 easy to process and form (for example: the auxiliary air duct 31 is formed as one piece by injection molding).

[0037] Specifically, the air outlet structure further includes a switch unit 40, which is disposed at the air inlet 311 and is used to control whether the air inlet 311 is connected to the air outlet duct 50. By providing the switch unit 40, effective control over whether the air inlet 311 is connected to the air outlet duct 50 is achieved. When the air inlet 311 and the air outlet duct 50 are not required to be connected, the switch unit 40 can prevent the gas in the air outlet duct 50 from leaking through the auxiliary air duct 31.

[0038] like Figure 1 and Figure 2As shown, the switch unit 40 includes a closing plate 41, which is movably arranged at the air inlet 311, wherein the closing plate 41 has a closed state and an open state, as shown in FIG. Figure 3 As shown, in the closed state, the closing plate 41 closes the air inlet 311, and the auxiliary air duct 31 is disconnected from the air outlet duct 50; Figure 4 As shown, in the open state, the auxiliary air duct 31 is connected to the air outlet duct 50. By providing the closing plate 41, the switch unit 40 is simplified and lightweight in structure, and the reliability of the switch unit 40 is ensured.

[0039] In a specific embodiment of the present invention, the shape and size of the closing plate 41 are adapted to the air inlet 311 to further ensure the sealing performance of the closing plate 41 in the closed state.

[0040] In another specific embodiment of the present invention, Figure 3 and Figure 4 As shown, the inner wall of the auxiliary air duct 31 has a groove 313 for accommodating the closing plate 41. By providing the groove 313, the closing plate 41 is effectively accommodated when the closing plate 41 is in the open state, thereby preventing the closing plate 41 from obstructing the airflow in the auxiliary air duct 31 when in the open state, making the airflow in the auxiliary air duct 31 flow more smoothly.

[0041] Specifically, the switch unit 40 further includes a drive motor connected to the sealing plate 41 to drive the sealing plate 41 to rotate relative to the air inlet 311. The provision of the drive motor enables automatic adjustment of the sealing plate 41, providing structural support for the subsequent operation of the air conditioner's intelligent control switch unit 40.

[0042] In a specific embodiment of the present invention, the drive motor adopts an existing stepper motor or servo motor and is electrically connected to the central controller of the air conditioner to ensure that the central controller can adjust the rotation angle of the closing plate 41 with high precision and speed.

[0043] like Figure 2 As shown, the air outlet structure also includes an air guide structure 60, which is provided at the air outlet 312 to control the air in the auxiliary air duct 31 to blow toward the exterior member 20. By providing the air guide structure 60, the flow direction of the air in the auxiliary air duct 31 is reliably controlled, further ensuring that the air is blown toward the outer surface of the exterior member 20, thereby improving the effect of removing condensed water.

[0044] like Figure 2 and Figure 3As shown, the air guide structure 60 includes a guide channel 61, which is provided at the air outlet 312. The inlet of the guide channel 61 is connected to the air outlet 312, and the outlet of the guide channel 61 faces the exterior member 20. The provision of the guide channel 61 ensures that the air guide structure 60 effectively guides the flow of gas in the auxiliary air duct 31 while also ensuring the overall simplicity of the air guide structure 60.

[0045] In a specific embodiment of the present invention, the interior of the guide channel 61 has an air guide cavity, and the inlet of the guide channel 61 is connected to the outlet of the guide channel 61 through the air guide cavity. The air guide channel guides the gas at the air outlet 312 to the appearance part 20. The air guide cavity is a smooth channel with a set guide angle. The angle of the guide angle can be flexibly set according to actual use needs and processing requirements to ensure the guiding direction of the guide channel 61 for the gas; by setting the interior of the guide channel 61 smooth (that is, the air guide cavity is smooth), the aerodynamic noise is effectively reduced.

[0046] like Figure 1 and Figure 2 As shown, the anti-condensation structure 30 further includes a reinforcing rib 32, which is provided at the air outlet 312. The reinforcing rib 32 supports the air outlet 312, thereby effectively improving the strength and rigidity of the air outlet 312 and preventing foreign matter from falling into the air outlet 312.

[0047] Specifically, there are a plurality of reinforcing ribs 32, and the plurality of reinforcing ribs 32 are arranged at intervals at the air outlet 312. By providing a plurality of reinforcing ribs 32, the strength and rigidity of the air outlet 312 are further improved.

[0048] It should be noted that: in a specific embodiment of the present invention, multiple reinforcing ribs 32 are arranged at the air outlet 312 near the guide channel 61 to improve the barrier effect against external foreign matter; of course, under the condition of ensuring that there is no significant obstruction to the gas flow at the air outlet 312, multiple reinforcing ribs can also be provided inside the air outlet 312 and inside the guide channel 61 for support to further improve the rigidity and strength. The number, installation position and shape of the reinforcing ribs 32 can be flexibly set according to actual use requirements and processing requirements.

[0049] It should be noted that: in another embodiment of the present invention not shown in the figure, Figure 1 and Figure 2 The position of the reinforcing ribs 32 shown in the figure is replaced by multiple rotatable wind guide plates. On the one hand, the wind guide plates can also support the reinforcing ribs 32 and block foreign objects. On the other hand, the wind guide plates can also accurately adjust the direction of the airflow at the air outlet 312, further improving the working flexibility and applicability of the anti-condensation structure 30.

[0050] like Figure 1 and Figure 2 As shown, the anti-condensation structure 30 includes a rear shell 33, within which the auxiliary air duct 31 is located. The rear shell 33 is fixedly connected to the air outlet 10. The exterior member 20 is fixedly connected to the air outlet 10. The exterior member 20 is a curved plate that guides the air within the air outlet cavity 11 so that it is blown out in a predetermined direction. The rear shell 33 effectively protects and supports the auxiliary air duct 31.

[0051] It should be noted that: in actual use, the rear shell 33 can be a part of the air conditioner shell, so that the air conditioner does not need to set up an additional structure to carry the auxiliary air duct 31, which not only reduces the cost of the air conditioner, but also ensures the lightweight and simplicity of the air conditioner.

[0052] The present invention further provides an air conditioner including the above-mentioned air outlet structure. The air conditioner provided by the present invention does not cause condensation on the exterior member 20 , and the air conditioner has an aesthetically pleasing appearance, a good user experience, and has fewer temperature control and air blowing blind spots.

[0053] like Figure 5 As shown, the present invention also provides an anti-condensation control method, which is applied to the above-mentioned air conditioner. The anti-condensation control method includes the following steps: obtaining the dew point temperature T of the operating environment of the air conditioner dp and the outer surface 22 temperature T1 of the appearance part 20; the outer surface 22 temperature T1 and the dew point temperature T dp In contrast, when T1≤T dp When T1>T dp When the air inlet 311 is controlled to be disconnected from the air outlet duct 50. By setting the above steps, an effective anti-condensation method for the air conditioner is realized, and a method support is provided for the subsequent intelligent control anti-condensation working mode of the air conditioner.

[0054] Specifically, obtain the dew point temperature T dp The method includes the following steps: detecting the ambient temperature T of the air conditioner (for example, the indoor ambient temperature of the air conditioner), the ambient humidity RH (for example, the indoor ambient humidity of the air conditioner), and calculating the dew point temperature T according to T and RH. dp By setting various types of sensors (such as temperature sensors and humidity sensors) to detect the ambient temperature T and humidity RH of the air conditioner, the dew point temperature T is realized. dp accurate calculation of .

[0055] It is worth noting that in a specific embodiment of the present invention, the dew point temperature T is calculated using the known Magnus formula. dp, the specific formula is as follows:

[0056]

[0057] Among them, T dp is the dew point temperature (°C); T is the ambient temperature of the air conditioner (°C); RH is the ambient humidity (%); constants c and b are 237.7°C and 17.27 respectively;

[0058] Specifically, obtaining the temperature T1 of the outer panel 22 of the exterior member 20 includes the following steps: detecting the air outlet temperature T2 of the air conditioner and calculating the temperature T1 of the outer panel 22 of the exterior member 20 based on T2; or directly detecting the temperature T1 of the outer panel 22 of the exterior member 20. Using this method, the temperature T1 of the outer panel 22 of the exterior member 20 can be effectively determined.

[0059] It should be noted that in a specific embodiment of the present invention, the air outlet temperature T2 of the air conditioner is detected, and the temperature T1 of the outer panel 22 of the exterior member 20 is calculated based on T2 using an empirical formula. The empirical formula is as follows: T1 = a*T2, where a is a correction value. The correction value a is a specific value calculated before the air conditioner leaves the factory. That is, before the air conditioner leaves the factory, the temperature T1 of the outer panel 22 of the exterior member 20 and the air outlet temperature T2 of the air conditioner at that time are measured using temperature measuring equipment as a set of data. After multiple sets of measurements, multiple sets of data containing different air outlet temperatures T2 are obtained. Using common mathematical analysis methods, an approximate linear relationship between T1 and T2 is calculated, and the specific value of the correction value a is obtained. The correction value a corresponds to each air conditioner one-to-one. Using the above method, after knowing the air outlet temperature T2 of the air conditioner (usually, air conditioners have a temperature sensor to measure the air outlet temperature T2 of the air conditioner in real time), T1 can be calculated. There is no need to set up an additional temperature sensor to directly measure the temperature T1 of the outer panel 22 of the exterior member 20, thereby effectively reducing the cost of the air conditioner.

[0060] The present invention also provides another anti-condensation control method, which is applied to the above-mentioned air conditioner and includes the following steps: when the air conditioner is in cooling mode, controlling the air inlet 311 to be in continuous communication with the air outlet duct 50 so that the gas in the air outlet duct 50 is continuously blown toward the exterior member 20 through the air outlet 312; or, when the air conditioner is in cooling mode, controlling the air inlet 311 to be in periodic communication with the air outlet duct 50 so that the gas in the air outlet duct 50 is periodically blown toward the exterior member 20 through the air outlet 312. By providing continuous communication between the air inlet 311 and the air outlet duct 50, the air conditioner's condensation removal effect is maximized; by providing periodic communication between the air inlet 311 and the air outlet duct 50, the air conditioner's energy consumption is effectively reduced while ensuring the air conditioner's condensation removal effect, thereby achieving greater energy conservation and environmental protection.

[0061] It is worth noting that: in a specific embodiment of the present invention, when T1≤T dp When T1≤T dp When the air inlet 311 is controlled to be periodically connected to the air outlet duct 50, the gas in the air outlet duct 50 is periodically blown toward the exterior member 20 through the air outlet 312, thereby effectively reducing the energy consumption of the air conditioner and being more energy-saving and environmentally friendly.

[0062] In summary, the present invention provides an air outlet structure, an air conditioner and an anti-condensation control method. The present invention adjusts the temperature of the air at the outer panel 22 of the appearance part 20 by setting an auxiliary air duct 31, effectively balancing the temperature difference between the inner panel 21 and the outer panel 22 of the appearance part 20, thereby solving the condensation problem of the appearance part 20 of the air conditioner and improving the appearance of the air conditioner and the user experience; and by setting the auxiliary air duct 31, the ambient temperature at the outer panel 22 of the appearance part 20 (for example: the indoor temperature at the outer panel 22 of the appearance part 20) can also be effectively adjusted, effectively solving the problem of uneven ambient temperature adjustment of the air conditioner, and reducing the temperature adjustment dead corners and blowing dead corners of the air conditioner; at the same time, compared with the method of opening multiple through holes on the appearance part 20 in the prior art, the present invention will not destroy the integrity and aesthetics of the appearance of the appearance part 20, and is more conducive to the overall aesthetics of the air conditioner. In addition, the present invention adjusts the external air temperature at the outer panel 22 more evenly, and the temperature adjustment effect is fast, effectively avoiding the occurrence of aerodynamic noise.
