Description

Technical Field

[0001] This application relates to the field of air conditioner technology, for example to an indoor air conditioner unit and an air conditioner. Background Technology

[0002] Air conditioners are common appliances used to improve the indoor environment. Their temperature regulation capabilities and airflow methods directly affect the user experience. Based on their installation method, air conditioners include wall-mounted indoor units, floor-standing indoor units, and portable indoor units, among others.

[0003] Wall-mounted air conditioner indoor units are installed on the wall inside the user's room, reducing the floor space occupied, which is why they are popular with users. Existing wall-mounted air conditioner indoor units have air inlets on the top panel and air outlets on the front panel, thus forming an airflow path of upward air intake and front air exhaust.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The airflow path design with top air intake and front air outlet makes it impossible to install the indoor unit of the air conditioner close to the ceiling, and also makes the unit body thicker.

[0006] It should be noted that the information disclosed in the background section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides an indoor air conditioning unit and an air conditioner to solve the problems of indoor air conditioning units not being able to be installed flush against the ceiling and having a relatively thick body.

[0009] In some embodiments, the indoor unit of the air conditioner includes:

[0010] The housing includes a bottom plate with an air outlet and a first side plate with an air inlet;

[0011] A heat exchanger, disposed within a housing, includes a first heat exchange section and a second heat exchange section connected below the first heat exchange section;

[0012] The first heat exchange section has an angle of α with the horizontal direction, and the second heat exchange section has an angle of β with the horizontal direction, where α > β.

[0013] In this embodiment, the indoor unit of the air conditioner adopts an airflow path design with side air intake and bottom air outlet. Air enters the casing from the air inlet on the first side panel, exchanges heat with the heat exchanger, and is then blown into the room from the air outlet on the bottom panel. This allows the top panel of the indoor unit to be installed flush against the top wall. Furthermore, the first and second heat exchange sections form a two-section folded structure, which fully utilizes the space within the casing to achieve a larger heat exchange area within a limited space, resulting in a thinner casing. Moreover, to adapt to the side air intake and bottom air outlet structure, the included angles α and β are designed differently, i.e., α > β, which helps optimize the distribution of airflow velocity and improves the overall heat exchange efficiency of the heat exchanger. Thus, the air conditioner indoor unit achieves an ultra-thin design while ensuring high heat exchange efficiency.

[0014] Optionally, α ≥ 30°; and / or,

[0015] β≥30°.

[0016] In this embodiment, further limiting the values ​​of α and β is beneficial to improving the heat exchange efficiency of the heat exchanger.

[0017] Optionally, the height of the first heat exchange section is h1, the height of the second heat exchange section is h2, and h1 / h2 < 1.

[0018] In this embodiment, by limiting the ratio of h1 and h2, the structure of side air intake and bottom air outlet can be further adapted, thereby improving the overall heat exchange efficiency of the heat exchanger.

[0019] Optionally, both the first heat exchange section and the second heat exchange section are inclined inward toward the interior of the casing, forming an included angle γ; the indoor unit of the air conditioner also includes:

[0020] The fan is positioned between the heat exchanger and the air outlet, and is located within the angular domain of the included angle γ.

[0021] In this embodiment, the fan is placed within the angular region of γ, which is beneficial for the airflow to fully contact and exchange heat with the heat exchanger when the fan is running.

[0022] Optionally, the axis of the fan is parallel to the plane where the first heat exchange section is located and the plane where the second heat exchange section is located;

[0023] Wherein, the distance from the fan axis to the plane where the first heat exchange section is located is d1, and the distance from the fan axis to the plane where the second heat exchange section is located is d2, and 1.2≤d1 / d2≤1.5.

[0024] In this embodiment, by defining the proportional relationship between d1 and d2, the vertical position of the fan in the angular domain of γ can be optimized, further improving the contact effect between the air and the heat exchanger.

[0025] Optionally, the vertical distance between the fan axis and the upper end of the first heat exchange section is d3, and the vertical distance between the fan axis and the lower end of the second heat exchange section is d4, where 2.8 ≤ d3 / d4 ≤ 3.2.

[0026] In this embodiment, by defining the ratio between d3 and d4, the horizontal position of the fan in the angular domain of γ can be optimized, which is beneficial for a more compact relative position between the fan and the heat exchanger.

[0027] Optionally, the base plate is perpendicular to the first side plate, and the axis of the fan is parallel to the base plate;

[0028] The distance between the fan axis and the base plate is d5, and the distance between the fan axis and the first side plate is d6, where 0.3≤d5 / d6≤0.5.

[0029] In this embodiment, by limiting the ratio of d5 and d6, the relative positions of the fan, air inlet, and air outlet can be optimized, which is conducive to smooth airflow.

[0030] Optionally, the fan diameter is d7, the height of the first heat exchange section is h1, and the height of the second heat exchange section is h2.

[0031] Among them, 4.5≤d7 / ≤5.5.

[0032] In this embodiment, by limiting the proportional relationship between h1, h2 and d7, the spatial arrangement of the fan and heat exchanger can be further optimized, making the fan and heat exchanger more compact within the casing.

[0033] Optionally, the housing also includes:

[0034] The second side panel is arranged opposite to the first side panel and can be installed against the side wall of the wall.

[0035] The top plate is arranged opposite to the bottom plate and can be installed against the top wall of the wall.

[0036] In this embodiment, the second side panel is installed against the side wall of the wall, eliminating the gap between the traditional air conditioner and the wall side wall, reducing the depth of the casing to be flush with the wall, and saving approximately [amount missing] lateral space. The top panel is installed against the top wall, preventing dust accumulation and foreign objects from entering, while also reducing the height occupied by the unit. Thus, this wall-mounted method of the second side panel and top panel facilitates the ultra-thin design of the air conditioner indoor unit.

[0037] In some embodiments, the air conditioner includes the indoor unit.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0059] This disclosure provides an indoor air conditioning unit, which includes a housing 1 and a heat exchanger 2. For example... Figure 1As shown, the housing 1 includes a bottom plate 11 with an air outlet 111 and a first side plate 12 with an air inlet 121. A heat exchanger 2 is disposed within the housing 1, and the heat exchanger 2 includes a first heat exchange section 21 and a second heat exchange section 22 connected below the first heat exchange section 21. The first heat exchange section 21 makes an angle α with the horizontal direction, and the second heat exchange section 22 makes an angle β with the horizontal direction, where α > β. A schematic diagram of the angles α and β and the horizontal direction is shown below. Figure 2 As shown.

[0060] In this embodiment, the indoor unit of the air conditioner adopts an airflow path design with side air intake and bottom air outlet. Air enters the housing 1 from the air inlet 121 on the first side plate 12, exchanges heat with the heat exchanger 2, and is then blown into the room from the air outlet 111 on the bottom plate 11. This allows the top plate 14 of the indoor unit to be installed against the top wall of the wall. Furthermore, the first heat exchange section 21 and the second heat exchange section 22 form a two-section folded structure, which can fully utilize the space within the housing 1 to achieve a larger heat exchange area within a limited space, facilitating a thinner design for the housing 1. Moreover, to adapt to the side air intake and bottom air outlet structure, the included angles α and β are designed differently, i.e., α > β, which helps optimize the distribution of airflow velocity and improves the overall heat exchange efficiency of the heat exchanger 2. Thus, the air conditioner indoor unit achieves an ultra-thin design while ensuring high heat exchange efficiency.

[0061] Optionally, the first side panel 12 is the front-facing side panel of the housing 1. In this embodiment, the indoor unit of the air conditioner has a large space in front of it after installation. Designing the first side panel 12 as a front component is beneficial to increasing the air intake volume of the air inlet 121.

[0062] Optionally, the first side plate 12 is the left-facing side plate of the housing 1.

[0063] Optionally, the first side plate 12 is the right-side side plate of the housing 1.

[0064] Optionally, such as Figure 1 As shown, the housing 1 also includes a second side plate 13 and a top plate 14. The second side plate 13 is arranged opposite to the first side plate 12 and can be installed against the side wall of the wall. The top plate 14 is arranged opposite to the bottom plate 11 and can be installed against the top wall of the wall.

[0065] In this embodiment, the second side panel 13 is installed against the side wall of the wall, which eliminates the gap between the traditional air conditioner and the side wall, reducing the depth of the casing 1 to be flush with the wall and saving lateral space. The top panel 14 is installed against the top wall, which prevents dust accumulation and foreign objects from entering from the top, while also reducing the height occupied by the unit. Thus, the wall-mounted installation method of the second side panel 13 and the top panel 14 facilitates the ultra-thin design of the air conditioner indoor unit.

[0066] Optionally, if the first side plate 12 is the front-facing side plate of the housing 1, the second side plate 13 is the rear-facing side plate of the housing 1.

[0067] Optionally, α ≥ 30°. In this way, by further limiting the value of α, it is beneficial to improve the heat exchange efficiency of heat exchanger 2.

[0068] Optionally, the value of α can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65° or 70°.

[0069] Optionally, β ≥ 30°. In this way, by further limiting the value of β, it is beneficial to improve the heat exchange efficiency of heat exchanger 2.

[0070] Optionally, the value of β can be selected as 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65° or 70°.

[0071] Optionally, such as Figure 3 As shown, the height of the first heat exchange section 21 is h1, the height of the second heat exchange section 22 is h2, and h1 / h2 < 1.

[0072] In this embodiment, h1 and h2 are illustrated as follows: Figure 3 As shown, the first heat exchange section 21 has a relatively large angle α with the horizontal direction, but its height h1 is relatively small. The second heat exchange section 22 has a relatively small angle β with the horizontal direction, but its height h2 is relatively large. This differentiated design can further adapt to the structure of side air inlet and bottom air outlet, thereby improving the overall heat exchange efficiency of the heat exchanger 2.

[0073] Optionally, the value of h1 / h2 can be 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 or 0.9.

[0074] Optionally, such as Figure 2 As shown, the first heat exchange section 21 and the second heat exchange section 22 are both inclined toward the interior of the casing 1, forming an included angle γ. The indoor unit of the air conditioner also includes a fan 3. The fan 3 is disposed between the heat exchanger 2 and the air outlet 111, and is located within the angular region of the included angle γ.

[0075] In this embodiment, the lower end of the first heat exchange section 21 and the upper end of the second heat exchange section 22 are connected adjacently. The upper end of the first heat exchange section 21 is inclined towards the interior of the shell 1, and the lower end of the second heat exchange section 22 is inclined towards the interior of the shell 1, so that the opening of the included angle γ formed by the two sections faces the interior of the shell 1. The angle region is the area enclosed by two rays or straight lines that form the included angle γ, originating from the same vertex, and its boundary is determined by the direction angle of the two rays. Placing the fan 3 within the angle region of γ is beneficial for the airflow to fully contact and exchange heat with the heat exchanger 2 when the fan 3 is running.

[0076] Optionally, a water receiving tray 4 is provided below the heat exchanger 2, and the vertical projections of the first heat exchange section 21 and the second heat exchange section 22 are both located inside the water receiving tray 4. When the surface temperature of the heat exchanger 2 is lower than the air dew point temperature, water vapor in the air will condense into condensate on the surface of the heat exchanger 2. In this way, the water receiving tray 4 can collect the condensate and then discharge it to the outside of the shell 1 through the drain pipe.

[0077] Optionally, such as Figure 1 As shown, the indoor unit of the air conditioner also includes a duct 5, which is located within the angular region of γ, and the fan 3 is installed inside the duct 5.

[0078] Optionally, the upper end of the first heat exchange section 21 is inclined toward the interior of the shell 1, and the upper end of the first heat exchange section 21 overlaps the upper edge of the air duct 5. The lower end of the second heat exchange section 22 is inclined toward the interior of the shell 1, and the lower end of the second heat exchange section 22 overlaps the lower edge of the air duct 5.

[0079] In this embodiment, the heat exchanger 2 completely blocks the inlet of the air duct 5, which can reduce the airflow bypass phenomenon, ensure that more airflow passes through the surface of the heat exchanger 2, increase the contact time between the heat exchange area and the airflow, and thus improve the heat exchange efficiency.

[0080] Optionally, the outlet of the air duct 5 extends to the air outlet 111 of the housing 1. In this way, the air duct outlet extends directly to the air outlet 111, avoiding airflow loss caused by multiple turns or diffusions of airflow inside the housing 1.

[0081] Optionally, the fan 3 is a cross-flow fan 3, and the axis 31 of the fan 3 is arranged horizontally. A schematic cross-sectional view of the axis 31 of the fan 3 is shown below. Figure 1 As shown.

[0082] Optionally, the axis 31 of the fan 3 is parallel to the plane containing the first heat exchange section 21 and the plane containing the second heat exchange section 22. The distance from the axis 31 of the fan 3 to the plane containing the first heat exchange section 21 is d1, and the distance from the axis 31 of the fan 3 to the plane containing the second heat exchange section 22 is d2, and 1.2≤d1 / d2≤1.5.

[0083] In this embodiment, d1 and d2 are illustrated as follows: Figure 4 As shown, the smaller d1 is, the higher the fan 3 is positioned. The smaller d2 is, the lower the fan 3 is positioned. By limiting the ratio of d1 and d2, the vertical position of the fan 3 within the angular domain of γ can be optimized, further improving the contact effect between the air and the heat exchanger 2.

[0084] Optionally, the value of d1 / d2 can be 1.2, 1.3, 1.4 or 1.5.

[0085] Optionally, the vertical distance between the axis 31 of the fan 3 and the upper end of the first heat exchange section 21 is d3, and the vertical distance between the axis 31 of the fan 3 and the lower end of the second heat exchange section 22 is d4, where 2.8 ≤ d3 / d4 ≤ 3.2.

[0086] In this embodiment, d3 and d4 are illustrated as follows: Figure 5 As shown. The smaller d3 is, the closer the fan 3 is to the first heat exchange section 21. The smaller d4 is, the closer the fan 3 is to the second heat exchange section 22. By limiting the ratio of d3 and d4, the horizontal position of the fan 3 in the angular domain of γ can be optimized, which is beneficial to a more compact relative position between the fan 3 and the heat exchanger 2.

[0087] Optionally, the values ​​of d3 / d4 can be 2.8, 2.9, 3, 3.1 or 3.2.

[0088] Optionally, the base plate 11 is perpendicular to the first side plate 12, and the axis 31 of the fan 3 is parallel to the base plate 11. The distance between the axis 31 of the fan 3 and the base plate 11 is d5, and the distance between the axis 31 of the fan 3 and the first side plate 12 is d6, where 0.3≤d5 / d6≤0.5.

[0089] In this embodiment, d5 and d6 are illustrated as follows: Figure 5 As shown. The smaller d5 is, the closer the fan 3 is to the air inlet 121. The smaller d6 is, the closer the fan 3 is to the air outlet 111. By limiting the ratio of d5 and d6, the relative position of the fan 3 with the air inlet 121 and the air outlet 111 can be optimized, which is conducive to smooth air circulation.

[0090] Optionally, the values ​​of d5 / d6 can be 0.3, 0.4, or 0.5.

[0091] Optionally, the diameter of the fan 3 is d7, the height of the first heat exchange section 21 is h1, and the height of the second heat exchange section 22 is h2, wherein 4.5≤d7 / (h2-h1)≤5.5.

[0092] In this embodiment, h1, h2, and d7 are illustrated as follows: Figure 3 As shown. By limiting the proportional relationship between h1, h2 and d7, the spatial arrangement of the fan 3 and the heat exchanger 2 can be further optimized, making the fan 3 and the heat exchanger 2 more compact within the shell 1.

[0093] Optionally, the value of d7 / (h2-h1) can be 4.5, 4.6, 4.7, 4.8, 4.9, 5, 5.1, 5.2, 5.3, 5.4 or 5.5.

[0095] In this embodiment, the air conditioner includes an indoor unit and an outdoor unit. The indoor and outdoor units work together through refrigerant piping and electrical wiring to achieve functions such as cooling, heating, and dehumidification. With the indoor unit employing a side-intake and bottom-outtake airflow path design, and the first heat exchange section 21 and the second heat exchange section 22 forming a two-section folded structure, and with differentiated designs for the included angles α and β, the indoor unit can be installed flush with the ceiling, and while achieving an ultra-thin design, heat exchange efficiency is ensured.
