[0038] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] likeFigure 1 As shown, the air conditioner of this utility model embodiment includes a housing 1, a centrifugal fan 2, a bottom heat exchanger 3, a first heat exchanger 4, and a second heat exchanger 5.

[0040] The housing 1 is provided with a bottom air inlet 11, a first air inlet 12, a second air inlet 13 and an air outlet 14. The bottom air inlet 11 is located at the bottom of the housing 1, the first air inlet 12 and the second air inlet 13 are located on the side of the housing 1 and are arranged opposite to each other in the length direction of the housing 1, and the air outlet 14 is located above the bottom air inlet 11.

[0041] For example, such as Figure 1 and Figure 2 As shown, the housing 1 can be roughly rectangular, and the length direction of the housing 1 can be left and right. The bottom air inlet 11 can be located on the bottom surface of the housing 1, the first air inlet 12 can be located on the left side of the housing 1, the second air inlet 13 can be located on the right side of the housing 1, and the air outlet 14 can be located on the front side of the housing 1, and the air outlet 14 can be arranged adjacent to the top surface of the housing 1.

[0042] Centrifugal fan 2 is assembled inside casing 1, and bottom heat exchanger 3 is located between bottom air inlet 11 and centrifugal fan 2 for heat exchange with the airflow flowing in from bottom air inlet 11. For example, Figure 1 and Figure 2 As shown, the centrifugal fan 2 can be fixed inside the housing 1, and the bottom heat exchanger 3 can also be installed inside the housing 1. In the vertical direction, the bottom heat exchanger 3 can be located between the centrifugal fan 2 and the bottom air inlet 11.

[0043] The first heat exchanger 4 is located between the first air inlet 12 and the centrifugal fan 2 and is used for heat exchange with the airflow flowing in from the first air inlet 12. The second heat exchanger 5 is located between the second air inlet 13 and the centrifugal fan 2 and is used for heat exchange with the airflow flowing in from the second air inlet 13.

[0044] For example, such as Figure 1 As shown, both the first heat exchanger 4 and the second heat exchanger 5 can be located inside the shell 1, wherein the first heat exchanger 4 can be located on the left side of the centrifugal fan 2, and the second heat exchanger 5 can be located on the right side of the centrifugal fan 2.

[0045] When the centrifugal fan 2 is running, external air can be drawn into the housing 1 through the bottom air inlet 11, the first air inlet 12, and the second air inlet 13. The airflow entering through the bottom air inlet 11 can exchange heat with the bottom heat exchanger 3, the airflow entering through the first air inlet 12 can exchange heat with the first heat exchanger 4, and the airflow entering through the second air inlet 13 can exchange heat with the second heat exchanger 5. This allows for the regulation of the airflow temperature. The airflow after heat exchange is then concentrated at the air outlet 14 by the centrifugal fan 2 and discharged through the air outlet 14, thus meeting the needs of indoor cooling and heating.

[0046] The projections of the first heat exchanger 4 and the second heat exchanger 5 onto a vertical plane parallel to their length are both linear. For example, as... Figure 1 As shown, the length direction can be left and right, and the vertical plane can be a vertical plane parallel to the left and right direction. The projections of the first heat exchanger 4 and the second heat exchanger 5 on this vertical plane can both be roughly straight lines and are arranged to extend along the up and down direction.

[0047] Therefore, the airflow flowing in through the first air inlet 12 and the second air inlet 13 can be substantially perpendicular to the first heat exchanger 4 or the second heat exchanger 5, which is beneficial to improving heat exchange efficiency and heat exchange effect.

[0048] The air conditioner of this utility model embodiment adopts an upward air outlet design, that is, compared with the downward air outlet design, the air outlet 14 is set at a higher position, which allows the air conditioner to have a larger air supply angle and also helps to increase the overall air supply distance.

[0049] Secondly, the housing 1 is provided with three air inlets: a bottom air inlet 11, a first air inlet 12, and a second air inlet 13, which allows air to enter from the bottom and both sides of the air conditioner. This greatly increases the air intake area and the unit air intake volume of the air conditioner, thereby improving the efficiency and speed of indoor air circulation. This is conducive to achieving rapid cooling and heating, and enhances the user experience.

[0050] In some embodiments, such as Figures 1 to 3 As shown, the centrifugal fan 2 includes a volute 21 and a centrifugal fan blade 22. The volute 21 is connected to the bottom air inlet 11, the first air inlet 12, the second air inlet 13, and the air outlet 14.

[0051] For example, the material of the volute 21 can be metal, plastic, etc. The volute 21 as a whole can be a whistle-shaped structure and include a cylindrical part and a tube part. The outer periphery of the cylindrical part and both ends of the cylindrical part are open structures, thereby meeting the usage requirements of the bottom air inlet 11, the first air inlet 12, and the second air inlet 13 entering the volute 21.

[0052] The tube body can generally extend in the front-to-back direction. The rear end of the tube body can be connected to the cylindrical part, and the front end of the tube body can also be an open structure and connected to the air outlet 14, thus meeting the needs of sending out airflow.

[0053] like Figure 1 and Figure 2 As shown, the centrifugal fan blade 22 is disposed inside the volute 21, and the rotation axis of the centrifugal fan 2 can extend in the left and right direction. When the centrifugal fan 2 is running, the airflow can flow into the housing 1 through the bottom air inlet 11, the first air inlet 12, and the second air inlet 13 respectively. After heat exchange with the bottom heat exchanger 3, the first heat exchanger 4, and the second heat exchanger 5, the airflow can enter the volute 21 and finally be discharged through the air outlet 14.

[0054] In some embodiments, the distance between the volute 21 and the first air inlet 12 in the longitudinal direction is L1, where 80mm ≤ L1 ≤ 150mm. For example, as... Figure 1 As shown, distance L1 can be the distance between the left side wall of the volute 21 and the first air inlet 12. Specifically, distance L1 can be 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm, 130mm, 135mm, 140mm, 145mm, 150mm, etc. Distance L1 within this range can increase the airflow through the first air inlet 12.

[0055] In some embodiments, the distance between the volute 21 and the second air inlet 13 in the longitudinal direction is L2, where 80mm ≤ L2 ≤ 150mm. For example, as... Figure 1 As shown, distance L2 can be the distance between the right side wall of the volute 21 and the second air inlet 13. Distance L1 can specifically be 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm, 130mm, 135mm, 140mm, 145mm, 150mm, etc. Distance L2 within this range can increase the airflow through the second air inlet 13.

[0056] In some embodiments, the distance between the first heat exchanger 4 and the first air inlet 12 in the longitudinal direction is L3, where 30mm ≤ L3 ≤ 60mm. For example, as... Figure 1 As shown, distance L3 can be the distance between the left side wall of the first heat exchanger 4 and the first air inlet 12. Specifically, distance L3 can be 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, etc. Distance L3 within this range can increase the air volume flowing in through the first air inlet 12.

[0057] In some embodiments, the distance between the second heat exchanger 5 and the second air inlet 13 in the longitudinal direction is L4, where 30mm ≤ L4 ≤ 60mm. For example, as... Figure 1 As shown, distance L4 can be the distance between the right side wall of the second heat exchanger 5 and the second air inlet 13. Specifically, distance L4 can be 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, etc. Within this range, distance L4 can increase the airflow through the second air inlet 13.

[0058] In some embodiments, the distance between the first heat exchanger 4 and the volute 21 in the longitudinal direction is L5, where 20mm ≤ L5 ≤ 120mm. For example, as... Figure 1 As shown, distance L5 can be the distance between the right side wall of the first heat exchanger 4 and the left side wall of the volute 21. Specifically, distance L5 can be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, etc. Distance L5 within this range can increase the airflow through the first air inlet 12.

[0059] In some embodiments, the distance between the second heat exchanger 5 and the volute 21 in the longitudinal direction is L6, where 20mm ≤ L6 ≤ 120mm. For example, as... Figure 1 As shown, distance L6 can be the distance between the left side wall of the second heat exchanger 5 and the right side wall of the volute 21. Specifically, distance L6 can be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, etc. Distance L6 within this range can increase the airflow through the second air inlet 13.

[0060] In some embodiments, the first heat exchanger 4 and the second heat exchanger 5 are both plate heat exchangers, and the projections of the first heat exchanger 4 and the second heat exchanger 5 on the vertical plane are both arranged to extend along the vertical direction.

[0061] For example, such as Figure 3 As shown, both the first heat exchanger 4 and the second heat exchanger 5 can be flat plate structures. The first heat exchanger 4 and the second heat exchanger 5 can be arranged in parallel at intervals in the left-right direction, and both the first heat exchanger 4 and the second heat exchanger 5 can be arranged perpendicular to the left-right direction. Therefore, the airflow flowing in through the first air inlet 12 and the second air inlet 13 can be perpendicular to the first heat exchanger 4 and the second heat exchanger 5 respectively, thus ensuring sufficient heat exchange efficiency.

[0062] In some embodiments, such as Figures 1 to 3As shown, the air conditioner also includes a bottom grille 6, a first grille 7, and a second grille 8. The bottom grille 6, the first grille 7, and the second grille 8 can all be roughly flat.

[0063] The bottom grille 6 is located at the bottom air inlet 11, and the bottom heat exchanger 3 is located between the bottom grille 6 and the centrifugal fan 2. Specifically, the bottom grille 6 can be installed inside the bottom air inlet 11 with fasteners such as screws, thereby blocking foreign objects.

[0064] The first grille 7 is located at the first air inlet 12, the first heat exchanger 4 is located between the first grille 7 and the centrifugal fan 2, the second grille 8 is located at the second air inlet 13, and the second heat exchanger 5 is located between the second grille 8 and the centrifugal fan 2. The first grille 7 can be fixed inside the first air inlet 12 with fasteners, and the second grille 8 can be fixed inside the second air inlet 13 with fasteners, thus both the first grille 7 and the second grille 8 can serve to block foreign objects.

[0065] In some embodiments, the air conditioner includes a water tray 9, which is disposed between the bottom grille 6 and the bottom heat exchanger 3, and in the longitudinal direction, the length dimension M of the water tray 9 is not less than either the distance M1 between the first heat exchanger 4 and the second heat exchanger 5 or the length dimension M2 of the bottom heat exchanger 3.

[0066] For example, such as Figure 1 As shown, the length direction can be left and right, and the water receiving tray 9 can extend along the left and right direction. The length dimension M is the dimension of the water receiving tray 9 in the left and right direction. The distance M1 is the distance in the left and right direction between the surface of the first heat exchanger 4 adjacent to the first air inlet 12 and the surface of the second heat exchanger 5 adjacent to the second air inlet 13. The bottom heat exchanger 3 extends generally along the left and right direction, and the length dimension M2 is the dimension of the bottom heat exchanger 3 in the left and right direction.

[0067] like Figure 1 As shown, the length dimension M must be greater than the distance M1, and the length dimension M must also be greater than the length dimension M2. Furthermore, the left end of the water receiving tray 9 can extend beyond the left sides of both the bottom heat exchanger 3 and the first heat exchanger 4, and the right end of the water receiving tray 9 can extend beyond the right sides of both the bottom heat exchanger 3 and the second heat exchanger 5. This allows the water receiving tray 9 to simultaneously meet the needs of collecting condensate dripping from the bottom heat exchanger 3, the first heat exchanger 4, and the second heat exchanger 5.

[0068] In some embodiments, such as Figure 2 As shown, the bottom heat exchanger 3 can be a V-shaped structure with the bottom heat exchanger 3 protruding downwards. The water receiving tray 9 can be located directly below the protruding part of the bottom heat exchanger 3, which facilitates the collection of condensate and other liquids dripping from the bottom heat exchanger 3.

[0069] In some embodiments, the housing 1 includes a base 15 and a panel 16, which are arranged opposite each other in a direction orthogonal to the length direction. The bottom air inlet 11 is located between the bottom side of the base 15 and the bottom side of the panel 16, and the air outlet 14 is located at the top of the panel 16.

[0070] For example, such as Figure 2 As shown, the base 15 and the panel 16 can be arranged opposite each other in the front-back direction, wherein the panel 16 can be located on the front side of the base 15. Both the base 15 and the panel 16 can extend in the left-right direction, and the bottom edge of the base 15 and the bottom edge of the panel 16 can be spaced apart in the front-back direction. The bottom air inlet 11 can be formed between the bottom edge of the base 15 and the bottom edge of the panel 16, and the bottom grille 6 can also be installed between the bottom edge of the base 15 and the bottom edge of the panel 16.

[0071] The air outlet 14 can be a square opening. The air outlet 14 can be located on the panel 16 and penetrate the panel 16 in the front-to-back direction. The air outlet 14 is arranged near the top edge of the panel 16, thereby fully meeting the needs of top air outlet.

[0072] The following describes an air conditioning system according to an embodiment of the present invention.

[0073] The air conditioning system of this utility model embodiment includes an air conditioner, which can be the air conditioner described in any of the above embodiments. Specifically, the air conditioner can be an indoor unit. The air conditioning system may also include an outdoor unit, corresponding connecting pipes, etc.

[0074] The air conditioning system of this utility model has advantages such as setting the air inlet of the air conditioner at the bottom, left and right sides, and placing the air outlet at the top, and using a centrifugal fan to deliver air. Compared with traditional air conditioners, this form has advantages such as large air pressure, large air angle, long air distance and large air volume. At the same time, the top air outlet form also has the advantages of avoiding cold air blowing directly on people and making the cooling more natural.

[0075] Secondly, under the action of the centrifugal fan, the airflow can enter from the bottom, left and right sides respectively. After flowing through the evaporator on the bottom, left and right sides, it can flow along the air duct and finally flow out at a certain angle at the air outlet.

[0076] This solves the problem of cold air sinking rapidly in cooling mode, allowing the cold air to flow evenly and slowly over a larger area. On the other hand, it also significantly increases the air volume and air delivery distance, enabling the airflow to evenly cover the entire room, improving the air delivery effect, ensuring the uniformity of temperature throughout the room, and thus guaranteeing the overall user comfort.
