Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an anti-condensation air conditioning wall unit. Background Art

[0002] As living standards rise, people's expectations for the user experience of air conditioners are also increasing. When a wall-mounted air conditioner is in cooling mode, the panel sits directly above the air outlet structure, creating vortices at the connection between the outlet and the panel. This can lead to uneven hot and cold areas on the panel and cause condensation. Passing beneath the air conditioner can cause dripping, resulting in a poor user experience. This unavoidable structure in wall-mounted air conditioners posed a significant challenge to R&D engineers.

[0003] Therefore, how to avoid condensation on the air conditioner panel is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide an anti-condensation air-conditioning wall unit, which can completely avoid condensation on the panel of the air-conditioning wall unit.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An anti-condensation air conditioner wall unit includes a panel, a housing, and an electric heating module, wherein:

[0007] A plurality of anti-condensation through holes are provided on one end of the panel close to the air outlet, and the plurality of anti-condensation through holes constitute a hole group area;

[0008] One end of the panel close to the air outlet is connected to the shell, and a gap greater than zero is formed between the outer side surface of the shell and the inner side surface of the panel;

[0009] The panel is provided with an air inlet, and when the air conditioner is in cooling operation, the gap between the panel and the shell forms a negative pressure gap;

[0010] The electric heating module is arranged in the negative pressure gap and is used to evaporate moisture that enters the negative pressure gap from the hole group area.

[0011] Preferably, the above-mentioned anti-condensation air-conditioning hanging unit further comprises a controller and a humidity sensor, and if the humidity sensor detects that the humidity in the negative pressure gap reaches a first preset humidity, the controller controls the electric heating module to start;

[0012] If the humidity sensor detects that the humidity in the negative pressure gap is zero or lower than a second preset humidity, the electric heating module stops heating, and the second preset humidity is lower than the first preset humidity.

[0013] Preferably, the humidity sensor is arranged on the electric heating module, and the electric heating module is arranged on the housing.

[0014] Alternatively, the above-mentioned anti-condensation air-conditioning hanging unit further includes a controller and a detector;

[0015] If the detector detects condensation on the inner side of the panel, the controller controls the electric heating module to start;

[0016] After the condensation disappears, the electric heating module stops heating.

[0017] Alternatively, the above-mentioned anti-condensation air-conditioning hanging unit further includes a controller and a detector;

[0018] If the detector detects that the amount of condensation accumulated on the inner side of the panel reaches a first preset value, the controller controls the electric heating module to start;

[0019] If the detector detects that the amount of condensation accumulated on the inner side of the panel is zero or lower than a second preset value, the electric heating module stops heating, and the second preset value is smaller than the first preset value.

[0020] Alternatively, in the above-mentioned anti-condensation air-conditioning hanging unit, during the cooling process, the electric heating module operates once every first preset time period, and each operation lasts for a second preset time period.

[0021] Preferably, in the above-mentioned anti-condensation air-conditioning hanging unit, the electric heating module is provided on the housing.

[0022] Preferably, in the above-mentioned anti-condensation air-conditioning wall unit, the air inlet is arranged on an end of the panel away from the air outlet.

[0023] Preferably, in the above-mentioned anti-condensation air conditioner, an air inlet grille is provided on the inner side of the air inlet, one end of the air inlet grille is connected to the air inlet, and the other end is connected to the housing;

[0024] One end of the shell is connected to the air inlet grille, and the other end is connected to the panel at the air outlet.

[0025] Preferably, in the above-mentioned anti-condensation air-conditioning wall unit, the distance between adjacent anti-condensation through holes in the hole group area is less than 2 mm, and:

[0026] The anti-condensation through hole is a circular through hole with a hole diameter of 0.3 mm to 1 mm;

[0027] Alternatively, the anti-condensation through hole is a polygonal through hole, the maximum side length of which is 0.3 mm to 1 mm;

[0028] Alternatively, the anti-condensation through hole is a strip-shaped hole with a width of 0.3 mm to 1 mm.

[0029] The anti-condensation air conditioner wall mounted unit provided by the present invention sucks in air from the air inlet during cooling operation. The air flows out from the air outlet after being cooled inside the air conditioner. During this process, a negative pressure is formed in the gap between the panel and the shell (hence it is referred to as a "negative pressure gap"). At this time, although the temperature of the hole group area is relatively low due to the proximity to the cold air flow at the air outlet, the porous structure of the hole group area can effectively prevent moisture from gathering into large water droplets. Moreover, when the moisture outside the panel increases (i.e., the amount of condensation increases) and thus blocks the anti-condensation through-holes in the hole group area, the negative pressure in the negative pressure gap causes the moisture attached to the hole group area to be sucked into the negative pressure gap (i.e., the inner side of the panel) through the anti-condensation through-holes. When the electric heating module is started, the moisture entering the inner side of the panel will evaporate into gas and be sucked away, and then merge into the air flow at the air inlet.

[0030] It can be seen that the anti-condensation air-conditioning wall unit provided by the present invention can prevent condensation from gathering into large water droplets and falling by setting hole group areas at positions where condensation is likely to occur on the panel and utilizing the negative pressure effect; moreover, an electric heating module is added to the anti-condensation air-conditioning wall unit, which can completely solve the problem of panel condensation and improve the air-conditioning usage experience.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] The first specific embodiment

[0044] To facilitate the description of the deficiencies of the prior art, the present invention provides the first specific embodiment, and the first specific embodiment provides a wall-mounted air conditioner.

[0045] Please refer to Figure 1 , Figure 1 which is a schematic internal structure diagram of the wall-mounted air conditioner provided by the first specific embodiment of the present invention.

[0046] The wall-mounted air conditioner provided by the first specific embodiment of the present invention includes an air inlet 1, an air inlet grille 2, a panel 3, a housing 4 and an air outlet. Among them, the air inlet grille 2 and the housing 4 are connected and are both located inside the panel 3. An air inlet 1 is provided at one end of the panel 3 away from the air outlet, and a condensation area 30 is provided at one end of the panel 3 close to the air outlet.

[0047] This wall-mounted air conditioner is prone to condensation, and the reasons for condensation are as follows:

[0048] 1) When the air conditioner operates in cooling mode, the air outlet is used to deliver cold air, and its wind direction is as shown by the arrow in Figure 1 . At this time, at the air outlet, air flow vortices are likely to occur at the corner of the connection structure between the panel 3 and the housing 4 (as can be seen from the direction of the curved upward arrow in Figure 1 ), resulting in a lower temperature T1 in the area of the panel 3 close to the air outlet and a higher temperature T2 in the area of the panel 3 away from the air outlet. Moreover, the air temperature T3 outside the panel 3 is also relatively high, that is, T1 < T2 < T3. This will cause hot and cold alternation, and thus moisture in the air will condense on the panel 3 and gradually form water droplets, resulting in condensation.

[0049] 2) The panel 3 and the shell 4 are two parts assembled and connected to each other. The connection formed by the two at the air outlet is a non-sealed structure. When the air conditioner is in cooling operation, a negative pressure gap is formed between the panel 3 and the shell 4. Combined with the effect of the air flow vortex, a small amount of cold air will always be poured in from the connection between the panel 3 and the shell 4. This will cause the temperature on the inside of the panel 3 to gradually decrease, while the temperature on the outside of the panel 3 is higher, forming alternating hot and cold, which will cause water droplets to form on the side with higher temperature (i.e., the outer surface of the panel 3), resulting in condensation.

[0050] Second specific embodiment

[0051] The second specific embodiment of the present invention provides a new type of anti-condensation air-conditioning wall mounted unit.

[0052] See also Figures 2 to 6 , Figure 2 A schematic diagram of the internal structure of an air-conditioning wall mounted unit provided in a second specific embodiment of the present invention; Figure 3 for Figure 2 Magnified view of the middle circle area; Figure 4 A schematic diagram of the distribution structure of the electric heating modules on the housing according to the second specific embodiment of the present invention; Figure 5 A schematic structural diagram of a panel provided in a second specific embodiment of the present invention; Figure 6 for Figure 5 Magnified view of the middle circle area.

[0053] The second embodiment of the present invention provides an anti-condensation air-conditioning wall mounted unit, comprising a panel 3, a housing 4 and an electric heating module 6.

[0054] A plurality of anti-condensation through holes are provided on one end of the panel 3 near the air outlet, and the plurality of anti-condensation through holes constitute a hole group area 5;

[0055] The end of the panel 3 close to the air outlet is connected to the shell 4, and there is a gap distance greater than zero between the outer side of the shell 4 and the inner side of the panel 3, that is, Figure 2 The negative pressure gap d is greater than zero;

[0056] An air inlet 1 is provided on the end of the panel 3 away from the air outlet, so that when the air conditioner is in cooling operation, a negative pressure gap is formed between the panel 3 and the housing 4;

[0057] The electric heating module 6 is disposed in the negative pressure gap and is used to evaporate the water that enters the negative pressure gap from the hole group area 5 .

[0058] The anti-condensation air conditioner wall mounted unit provided by the second specific embodiment of the present invention, when in cooling operation, draws air from the air inlet 1, and the air flows out from the air outlet after being cooled inside the air conditioner. During this process, a negative pressure is formed in the gap between the panel 3 and the shell 4 (hence it is referred to as a "negative pressure gap"). At this time, although the temperature of the hole group area 5 is relatively low due to its proximity to the cold air flow at the air outlet, the porous structure of the hole group area 5 can effectively prevent moisture from gathering into large water droplets. Moreover, when the moisture outside the panel 3 increases (i.e., the amount of condensation increases), thereby blocking the anti-condensation through-holes of the hole group area 5, the negative pressure in the negative pressure gap will cause the moisture attached to the hole group area 5 to be sucked into the negative pressure gap (i.e., the inside of the panel 3) through the anti-condensation through-holes. When the electric heating module 6 is started, the moisture entering the inside of the panel 3 will evaporate into gas, be sucked away, and merge into the air flow at the air inlet.

[0059] It can be seen that the anti-condensation air-conditioning wall unit provided by the first specific embodiment of the present invention can prevent condensation from gathering into large water droplets and falling by setting a hole group area 5 at a position where condensation is likely to occur on the panel 3 and utilizing the negative pressure effect; moreover, an electric heating module 6 is added to the anti-condensation air-conditioning wall unit, which can completely solve the problem of panel condensation and improve the air-conditioning usage experience.

[0060] It should be noted that the "hole group area" mentioned in this article refers to a part of the panel area composed of a plurality of densely distributed small holes. Among them, each anti-condensation through hole can be set as a circular through hole with a hole diameter of 0.3mm to 1mm, preferably 0.5mm; or, each anti-condensation through hole can be set as a triangular through hole, a rectangular through hole or other polygonal through hole with a maximum side length of 0.3mm to 1mm, preferably 0.5mm; or, each anti-condensation through hole can be set as a strip hole, and the width of each strip hole is 0.3mm to 1mm (preferably 0.5mm) and the length is longer. Specifically, no matter what shape of anti-condensation through hole is set, the distance between adjacent anti-condensation through holes in the hole group area 5 (this distance specifically refers to the minimum distance between the side wall of one anti-condensation through hole and the side wall of another anti-condensation through hole) is less than 2mm to avoid a large amount of moisture condensing on the panel between adjacent anti-condensation through holes. However, this is not limited to this. There can be a variety of design options for the specific shape and size of the anti-condensation through hole, as long as it can play the role of "preventing moisture from gathering into large water droplets" and "sucking moisture from the outside of the panel 3 to the inside". The present invention does not make specific limitations on this.

[0061] Specifically, the above-mentioned anti-condensation air-conditioning hanging unit also includes a controller and a humidity sensor. The humidity sensor is used to detect whether the humidity in the above-mentioned negative pressure gap reaches the preset humidity, and the humidity sensor and the electric heating module 6 are respectively connected to the controller signal.

[0062] During air conditioning operation, if the humidity sensor detects that the humidity within the negative pressure gap reaches a first preset humidity, the controller controls electric heating module 6 to start. If the humidity sensor detects that the humidity within the negative pressure gap is zero or below a second preset humidity (where the second preset humidity is lower than the first preset humidity), electric heating module 6 stops heating. In a specific implementation, the humidity sensor can be disposed on electric heating module 6, which is then disposed on housing 4.

[0063] Specifically, the electric heating module 6 on the housing 4 is arranged corresponding to the hole group area 5 on the panel 3, that is, the overall shape and coverage area of the electric heating module 6 are the same or similar to the hole group area 5. Figure 4 and Figure 5 As shown, the electric heating module 6 and the hole group area 5 are both arranged on the upper side of the air outlet, arranged in a strip shape, and are equal to or similar in length to the air outlet.

[0064] Specifically, in the aforementioned anti-condensation wall-mounted air conditioner, air inlet 1 is located on the end of panel 3, away from the air outlet. Air inlet grille 2 is located within air inlet 1, with one end connected to air inlet 1 and the other end connected to housing 4. Housing 4 is connected to air inlet grille 2 at one end and to panel 3 at the air outlet at the other end. Negative pressure gaps are formed between housing 4 and panel 3, as well as between air inlet grille 2 and panel 3.

[0065] Third specific embodiment

[0066] The third embodiment of the present invention provides an anti-condensation wall mounted air conditioner, which is similar to the anti-condensation wall mounted air conditioner provided in the second embodiment of the present invention. The only difference between the two is that:

[0067] The third embodiment of the present invention provides an anti-condensation wall-mounted air conditioner, comprising a controller and a detector. The detector is configured to detect whether condensation has formed on the inner side of the panel 3. Furthermore, the detector and the electric heating module 6 are each connected to the controller for signal transmission. If the detector detects condensation on the inner side of the panel 3, the controller activates the electric heating module 6. Once the condensation disappears, the electric heating module 6 stops heating.

[0068] Fourth specific embodiment

[0069] The fourth embodiment of the present invention provides an anti-condensation wall mounted air conditioner, which is similar to the anti-condensation wall mounted air conditioner provided in the second embodiment of the present invention. The only difference between the two is that:

[0070] The fourth embodiment of the present invention provides an anti-condensation wall-mounted air conditioner, comprising a controller and a detector. The detector is configured to detect whether the amount of condensation accumulated on the inner side of panel 3 has reached a preset value. Furthermore, the detector and electric heating module 6 are each signal-connected to the controller. If the detector detects that the amount of condensation accumulated on the inner side of panel 3 has reached a first preset value, the controller activates electric heating module 6. If the detector detects that the amount of condensation accumulated on the inner side of panel 3 is lower than a second preset value, electric heating module 6 stops heating. Specifically, the second preset value is zero, or a smaller value greater than zero and less than the first preset value, to ensure that the amount of condensation accumulated on panel 3 remains low.

[0071] Fifth specific embodiment

[0072] The fifth embodiment of the present invention provides an anti-condensation wall mounted air conditioner, which is similar to the anti-condensation wall mounted air conditioner provided in the second embodiment of the present invention. The only difference between the two is that:

[0073] In the anti-condensation wall-mounted air conditioner provided in the fifth specific embodiment of the present invention, the electric heating module 6 is a heating device capable of operating at preset time intervals. Specifically, during the cooling process, the electric heating module 6 operates once every first preset time interval, and each operation lasts for a second preset time interval. The first preset time interval and the second preset time interval are specifically set by the designer, as long as they can achieve the purpose of timely evaporation of water to prevent water from condensing and dripping on the panel 3; alternatively, the startup and operation mode of the electric heating module 6 can be set to several different mode options, and the user can make specific settings based on the actual environmental needs.

[0074] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
