Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] At present, most air conditioners on the market have the air inlet duct for delivering fresh air directly connected to the rear panel of the air conditioner shell. The shell is also provided with a return air outlet. The space between the return air outlet and the air inlet of the fresh air volute serves as a shared chamber for fresh air and indoor return air.

[0003] Since the fresh air and return air air streams share the same chamber, the pressure in the shared chamber will be too high during actual operation, hindering the fresh air from entering and causing excessive air volume loss. Summary of the Invention

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Please combine Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic structural diagram of the air conditioner provided in this embodiment. Figure 2 FIG2 is a cross-sectional view of the air conditioner 100 provided in this embodiment at a first viewing angle. The air conditioner 100 has the characteristics of higher air intake efficiency and smaller air volume loss.

[0027] The air conditioner 100 provided in this embodiment includes a housing 110, a fresh air volute 130, an air shield 150, a filter grille 170, and a filter device 190. The fresh air volute 130 is disposed within the housing 110, and the air shield 150 is also disposed within the housing 110. The air shield 150 and the fresh air volute 130 are detachably connected, and together they enclose an air collecting chamber 141, a pressurizing chamber 142, and an air supply chamber 143, which are sequentially connected. The air collecting chamber 141, the pressurizing chamber 142, and the air supply chamber 143 constitute the fresh air chamber of the air conditioner 100. The air-blocking member 150 is used to connect the air inlet pipe of the air conditioner 100 to introduce the fresh air into the air collecting chamber 141. The boosting chamber 142 is used to accelerate the fresh air in the air collecting chamber 141 and introduce it into the air supply chamber 143. The shell 110 and the fresh air volute 130 form a return air chamber 120. The air supply chamber 143 is connected to the return air chamber 120, and the return air chamber 120 is connected to the air inlet of the fresh air volute 130.

[0028] It can be seen that in actual application, before the fresh air enters the return air chamber (120) and mixes with the indoor return air, it is pressurized and accelerated by the boost chamber 142, and has a faster flow rate, so that the fresh air pressure is greater than the return air pressure, thereby improving the fresh air intake efficiency and reducing the fresh air volume loss.

[0029] In this embodiment, the internal space of the air collecting chamber 141, the boost chamber 142 and the air supply chamber 143 gradually decreases, that is, the fresh air will be continuously pressurized and accelerated in the process of flowing through the air collecting chamber 141, the boost chamber 142 and the air supply chamber 143 in sequence. In addition, the cross-sectional area of ​​the boost chamber 142 in the direction perpendicular to the fresh air flow direction gradually decreases from one end connected to the air collecting chamber 141 to the end connected to the air supply chamber 143. That is, the cross-sectional area of ​​the fresh air continues to decrease in the process of flowing through the boost chamber 142, so that the fresh air flow rate continues to increase. In other embodiments, according to actual application conditions, other structures or devices can also be provided in the boost chamber 142 to increase the fresh air flow rate.

[0030] In fact, in this embodiment, the air barrier 150 is arranged between the rear panel of the housing 110 and the fresh air volute 130, and the air barrier 150 is connected to the outer wall of the fresh air volute 130, together forming a fresh air chamber. Compared with the existing technology that uses the internal space of the housing 110 as the fresh air chamber, the volume of the fresh air chamber is greatly reduced, solving the problem of excessive accumulation of fresh air in the existing technology. In addition, the air barrier 150 and the fresh air volute 130 form a separate fresh air chamber, avoiding sharing the same chamber with the indoor return air of the air conditioner 100, reducing the pressure of the fresh air chamber, thereby ensuring that the fresh air can smoothly enter the fresh air chamber and reducing the air volume loss of the air conditioner 100.

[0031] Please refer to Figure 1 and Figure 3 , Figure 3 The figure shows a cross-sectional view of the air conditioner 100 provided in this embodiment from a second viewing angle. A return air vent 111 is provided on the housing 110. The portion of the housing 110 corresponding to the return air vent 111 and the fresh air volute 130 form a return air chamber 120. The return air chamber 120 is connected to the air inlet of the fresh air volute 130. The return air chamber 120 is used to receive indoor return air and direct the indoor return air into the air inlet of the fresh air volute 130.

[0032] It can be seen that the air conditioner 100 provided in this embodiment divides the internal space of the shell 110 by adding an air partition 150 to form an independent fresh air chamber and a return air chamber 120. The fresh air will not be mixed with the return air in the independent fresh air chamber, ensuring that the internal pressure of the fresh air chamber is maintained within a reasonable range, thereby ensuring the smooth intake of fresh air.

[0033] In addition, in this embodiment, in order to simplify the structure, an air supply chamber 143 is opened on the side wall of the fresh air chamber, and the air supply chamber 143 is connected to the return air chamber 120. The fresh air chamber is connected to the air inlet of the fresh air volute 130 through the air supply chamber 143 and the return air chamber 120 in turn.

[0034] It can be understood that in actual operation, the pressure of the fresh air chamber is higher than that of the return air chamber 120, and the return air in the return air chamber 120 cannot flow back to the fresh air chamber through the supply air chamber 143. The fresh air in the fresh air chamber smoothly enters the return air chamber 120 through the supply air chamber 143, and then enters the fresh air volute 130 through the air inlet of the fresh air volute 130.

[0035] The fresh air volute 130 is provided with a first sidewall 131, a second sidewall 133, and a third sidewall 135. The second sidewall 133 corresponds to the rear panel of the housing 110. The first and third sidewalls 131, 135 are respectively provided at opposite ends of the second sidewall 133. Both the first and third sidewalls 131, 135 are provided with air inlets. The air baffle 150 is connected to the second sidewall 133, and together they form a fresh air chamber. The housing 110, the first sidewall 131, and the third sidewall 135 respectively form two return air chambers 120. Specifically, two return air inlets 111 are provided on the housing 110, corresponding to the first and third sidewalls 131, 135.

[0036] In this embodiment, the two air inlets of the volute are respectively disposed on the first sidewall 131 and the third sidewall 135. That is, the two return air ports 111 formed by the housing 110, the first sidewall 131, and the third sidewall 135 are directly connected to the two air inlets of the volute. Air supply cavities 143 are provided at the junction of the second sidewall 133 with the first sidewall 131 and at the junction of the second sidewall 133 with the third sidewall 135. The two air supply cavities 143 are respectively connected to the two return air chambers 120.

[0037] In actual use, the air inlet duct of the air conditioner 100 conveys fresh air into the fresh air chamber enclosed by the air barrier 150 and the first side wall 131. The two return air ports 111 provided on the housing 110 direct the indoor return air into the two return air chambers 120. The fresh air in the fresh air chamber flows through the two air supply chambers 143 into the two return air chambers 120, where it mixes with the indoor return air. The two air flows then flow together into the corresponding air inlets of the fresh air volute 130.

[0038] Please refer to Figure 4 , Figure 4 The filter grille 170 is disposed in the air supply chamber 143 and is actually provided at one end of the air supply chamber 143 for initially filtering the fresh air flowing through the air supply chamber 143 .

[0039] The air conditioner 100 provided in this embodiment further includes a filter device 190, which is disposed at the air inlet of the fresh air volute 130 and is configured to filter the air entering the fresh air volute 130. The fresh air and return air in the return air chamber, after preliminary filtration, are filtered by the filter device 190 upon reaching the air inlet of the fresh air volute 130, thereby improving the safety and service life of the air conditioner 100.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 5 , Figure 5 FIG. 1 is a schematic diagram of the exploded structure of the air conditioner 100 provided in this embodiment.

[0041] In order to facilitate the installation of the wind shield 150, in this embodiment, a mating protrusion 1331 is provided on the second side wall 133 of the fresh air volute 130, and a covering portion 151 is provided on the wind shield 150. The covering portion 151 is in the shape of an arch bridge and covers the mating protrusion 1331.

[0042] When the air blocking piece 150 is installed on the second side wall 133 of the fresh air volute 130, it is only necessary to cover the covering part 151 on the mating protrusion 1331 to achieve rapid and accurate positioning of the air blocking piece 150 on the second side wall 133, which facilitates the subsequent fixing of the air blocking piece 150.

[0043] In this embodiment, the number of the boost chamber 142, the air supply chamber 143 and the return air chamber 120 are two, one end of each of the two boost chambers 142 is connected to the air collecting chamber 141, and the other end of each of the two boost chambers 142 is connected to the two air supply chambers 143 respectively, and the two air supply chambers 143 are connected to the two return air chambers 120 respectively.

[0044] In order to ensure that the fresh air in the air collecting chamber 141 can enter the two boosting chambers 142 more evenly, in this embodiment, a diverter portion 157 is provided on the wind blocking member 150. The diverter portion 157 is provided between the two boosting chambers 142 and is used to divert the fresh air in the air collecting chamber 141 into the two boosting chambers 142.

[0045] In addition, since one end of each of the two boost chambers 142 in this embodiment is connected to the bottom of the air collecting chamber 141, the arch-bridge-shaped covering portion 151 is also used to guide the fresh air entering the air collecting chamber 141 toward the bottom, thereby preventing the fresh air from accumulating in the air collecting chamber 141 and improving the efficiency of fresh air intake. In this embodiment, a threaded hole 1333 is provided on the second side wall 133, and a mounting through hole 153 is provided through the air blocking member 150. When the covering portion 151 is covered with the mating protrusion 1331, the threaded hole 1333 is aligned with the mounting through hole 153. The air blocking member 150 is connected to the second side wall 133 by screws that are screwed into the threaded hole 1333 through the mounting through hole 153, thereby achieving the installation of the air blocking member 150. When actually installing the wind blocking member 150, first cover the covering part 151 on the mating protrusion 1331. When the covering is completed, the mounting through hole 153 provided on the wind blocking member 150 is naturally aligned with the threaded hole 1333 provided on the second side wall 133. At this time, pass the screw through the mounting through hole 153 and screw it into the threaded hole 1333 until it is tightened to complete the installation of the wind blocking member 150.

[0046] In this embodiment, the air blocker 150 is generally plate-shaped, with a cover portion 151 disposed on one side of one end of the air blocker 150. To disassemble the air blocker 150, simply unscrew the screws. After unscrewing the screws, pull the end of the air blocker 150 away from the cover portion 151, causing the air blocker 150 to rotate about the cover portion 151. After rotating to a certain angle, the cover portion 151 and the mating protrusion 1331 are released, completing the disassembly of the air blocker 150. This makes disassembly and assembly of the air blocker 150 quick and easy, saving time and effort and facilitating maintenance and inspection.

[0047] It is understandable that, in other embodiments, the air blocking member 150 and the fresh air volute 130 may also be connected using other detachable connection methods such as snap fit, magnetic attraction, etc.

[0048] A fresh air port 155 is further provided on a side of the air shield 150 away from the cover portion 151. The fresh air chamber is connected to the fresh air port 155 and is used to connect to the air inlet duct of the air conditioner 100 to direct the fresh air transported therein into the fresh air chamber. In this embodiment, the fresh air port 155 is cylindrical and is further provided with reinforcing ribs and a fixing portion for securing the air inlet duct.

[0049] In addition, a plurality of diversion parts 157 are provided on one side of the fresh air chamber enclosed by the air partition 150. The plurality of diversion parts 157 are used to divert the fresh air introduced into the fresh air chamber by the air inlet pipe of the air conditioner 100 to the two air supply chambers 143, thereby increasing the speed of the fresh air entering the fresh air volute, avoiding the accumulation of fresh air in the fresh air chamber, and further improving the fresh air intake efficiency.

[0050] In summary, the air conditioner 100 provided in this embodiment adds an air barrier 150 to the existing structure of the air conditioner 100. This air barrier 150 is positioned within the housing 110 and connected to the fresh air volute 130, forming a fresh air chamber. Compared to the prior art, this reduces the volume of the fresh air chamber, solves the problem of excessive fresh air accumulation, and improves air intake efficiency.

[0051] Furthermore, the air shield 150 and the fresh air volute 130 form a separate fresh air chamber, preventing the fresh air from sharing the same intake chamber with the return air. This reduces the pressure in the fresh air chamber, thereby minimizing air volume loss. Furthermore, the air shield 150 and the fresh air volute 130 are detachably connected, facilitating removal and cleaning of the air shield 150 and maintenance and repair of the air conditioner 100, saving assembly and disassembly costs.

[0052] Therefore, the air conditioner 100 provided in this embodiment has the characteristics of high air intake efficiency, small air volume loss, and easy maintenance and repair.

[0053] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
