[0006] 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.

[0007] This disclosure provides an air conditioner sub-unit that solves the problems of easy deformation of the top surface and excessive noise of the sub-unit.

The concentrically arranged double-layered grilles form a frame structure, which can disperse top forces such as external pressure and vibration, improving the overall rigidity of the second housing's top surface and reducing the risk of deformation or cracking due to long-term use. Furthermore, the staggered grille openings can disperse sound wave energy in the airflow, reducing single-frequency noise generated by airflow impacting the grilles.

[0046] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0048] Combination Figures 1 to 5 As shown, this embodiment of the present disclosure provides an air conditioner, including a main unit 100 and a sub-unit 200. The main unit 100 includes a first housing 110, the sub-unit 200 is disposed removably within the first housing 110, and the sub-unit 200 includes a second housing 210.

[0049] The mother unit 100 serves as the main body, and the core components of the air conditioner, such as the indoor heat exchanger and indoor fan, are housed within the first casing 110. Figure 1 As shown, the lower part of the first housing 110 has a compartment 111, which is specifically designed to house the sub-unit 200, ensuring its safe and convenient storage while effectively saving space and maintaining the overall neatness of the product's appearance. The sub-unit 200, as an independent movable component, also possesses air conditioning functions such as temperature and humidity control. It can flexibly move in and out of the first housing 110 of the mother unit 100 according to actual needs. When rapid temperature control is required in a small, single space, such as a bedroom or study, the user can remove the sub-unit 200 from the mother unit 100 and place or install it directly in the target area to achieve localized temperature and humidity regulation, thus reducing energy consumption. When overall temperature control is required in a large space, such as a living room or open-plan office area, the sub-unit 200 can be stored back inside the mother unit 100, working in conjunction with it to improve overall cooling and heating efficiency and cover a wider temperature control range. This "integrated storage, separate use" design retains the overall operational advantages of traditional air conditioners while overcoming the shortcomings of flexibility and energy efficiency when using a single unit in a localized space. It is suitable for various scenarios such as homes and offices, bringing users a more intelligent and efficient comfort experience.

[0050] Optionally, the air conditioner also includes an outdoor unit, which houses a compressor and an outdoor heat exchanger. The main unit 100 is equipped with an indoor heat exchanger. The refrigerant circulation system mainly consists of four basic components: a compressor, an outdoor heat exchanger, a throttling device, and an indoor heat exchanger, forming a closed loop. The compressor is the heart of the refrigerant circulation system. Its main task is to draw in the low-temperature, low-pressure refrigerant gas from the indoor heat exchanger and compress it into a high-temperature, high-pressure gas. After entering the outdoor heat exchanger, the high-temperature, high-pressure refrigerant gas releases heat to the external environment through heat exchange with the outside air or cooling water, while simultaneously cooling itself and forming a high-pressure liquid. When the high-pressure liquid passes through the throttling device, its pressure is reduced, and some of the liquid evaporates into gas, absorbing heat from the surroundings and further lowering the temperature and pressure of the refrigerant. After entering the indoor heat exchanger, the low-pressure refrigerant liquid exchanges heat with the hot indoor air. The refrigerant absorbs heat from the hot air, gradually changing from a liquid to a gaseous state, thereby lowering the temperature of the indoor air and achieving the purpose of cooling the room. In this way, the refrigerant continuously circulates, forming a complete refrigeration cycle: the compressor compresses the refrigerant into a high-temperature, high-pressure gas; the outdoor heat exchanger cools it into a high-pressure liquid; the throttling device reduces the pressure of the refrigerant and causes it to partially evaporate; the indoor heat exchanger absorbs indoor heat, causing the refrigerant to evaporate back into gas, which then re-enters the compressor, completing one refrigeration cycle. During heating, the refrigerant flows in the opposite direction. Through this continuous refrigerant circulation, the air conditioner can effectively regulate indoor temperature, providing a comfortable indoor environment for people.

[0051] Optionally, the sub-unit 200 is equipped with a water tank and a water-spinning wheel. The water-spinning wheel is located inside the water tank, and when it rotates, it spins the water in the tank. Thus, when air flows through the spun water, it is humidified.

[0052] In this embodiment, the water-spinning wheel spins at high speed, atomizing water into tiny droplets. These droplets come into full contact with the air entering the second housing 200, rapidly increasing the humidity in the air. The design of the water-spinning wheel increases the contact area between the water and the air, thereby improving humidification efficiency. Furthermore, as the water-spinning wheel rotates, the water is evenly flung outwards, forming a fine mist. When air flows through this mist, it absorbs the moisture evenly, avoiding uneven humidification.

[0053] Optionally, an axial flow fan is provided above the water tank, with the axis of the axial flow fan arranged perpendicular to the bottom surface of the water tank.

[0054] In this embodiment, the humidified airflow is guided by the axial flow fan to be blown into the room from the first air outlet structure 220 on the top surface of the first housing 110 and / or the second air outlet structure 230 on the side of the first housing 110. The vertical arrangement of the axial flow fan's axis saves horizontal space, making the overall structure of the sub-unit 200 more compact.

[0055] Optionally, such as Figure 2 As shown, the top surface of the second housing 210 is provided with a first air outlet structure 220, which includes a first grille assembly 221 and a second grille assembly 222. Figure 3 As shown, the first grille assembly 221 includes a plurality of first grilles 2211 arranged along a first annular ring, with a first grille opening 2212 formed between adjacent first grilles 2211. The second grille assembly 222 includes a plurality of second grilles 2221 arranged along a second annular ring, with a second grille opening 2222 formed between adjacent second grilles 2221. The first and second annular rings are concentrically arranged, and the first grille openings 2212 and the second grille openings 2222 are staggered.

[0056] In this embodiment, a first air outlet structure 220 is provided on the top surface of the sub-unit 200 to achieve top-level air outlet. The first air outlet structure 220 adopts a double-layer staggered grille structure, that is, the first grille assembly 221 and the second grille assembly 222 are arranged concentrically, and the first grille opening 2212 and the second grille opening 2222 are staggered. The concentric ring-shaped double-layer grille forms a frame structure, which can disperse the top forces such as external pressure and vibration, improve the overall rigidity of the top surface of the second housing 210, and reduce the risk of deformation or cracking due to long-term use. In addition, the staggered grille openings can disperse the sound wave energy in the airflow, reducing the single-frequency noise generated by the airflow impacting the grille. Furthermore, the combination of concentric ring and staggered design can form a regular geometric pattern, enhancing the technological and modern feel of the sub-unit 200's appearance and meeting the user's needs for home aesthetics.

[0057] Optionally, such as Figure 4 As shown, the outer diameter of the first ring is d1, and the outer diameter of the second ring is d2. Where 1.2 ≤ d1 / d2 ≤ 2.

[0058] In this embodiment, the ratio of d1 / d2 is limited to between 1.2 and 2, so that the diameter of the outer first grid assembly 221 is large enough to provide the main support, and the diameter of the inner second grid assembly 222 is small to avoid structural redundancy, thereby achieving a balance between lightweight and high strength.

[0059] Optionally, the value of d1 / d2 can be 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 or 2.

[0060] Optionally, the difference between the outer diameter and the inner diameter of the first annulus is c1, and the difference between the outer diameter and the inner diameter of the second annulus is c2. Wherein, 1≤c1 / c2≤1.5.

[0061] In this embodiment, when c1 / c2 = 1, the annular width of the first grille assembly 221 and the annular width of the second grille assembly 222 are equal. When c1 / c2 > 1, the annular width of the first grille assembly 221 is larger, and the corresponding first grille opening 2212 is also larger, enabling the outer layer to form a larger air outlet range. At the same time, c1 / c2 ≤ 1.5, which avoids the annular width of the first grille assembly 221 from being too large, thereby ensuring that the inner layer also has sufficient air outlet volume.

[0062] Optionally, the values ​​of c1 / c2 can be 1, 1.1, 1.2, 1.25, 1.3, 1.4, 1.45 or 1.5.

[0063] Optionally, such as Figure 3 As shown, both the first grille 2211 and the second grille 2221 are configured to extend along an arc.

[0064] In this embodiment, the curved grille design conforms to the natural diffusion trajectory of airflow. When airflow exits from the grille opening, the grille extending along the curve reduces right-angle collisions between the airflow and the grille surface, decreasing turbulence and energy loss, and allowing the airflow to diffuse more smoothly into the surrounding area. Furthermore, the curved grille design can evenly distribute stress across the entire curved surface under load, improving the grille's resistance to deformation.

[0065] Optionally, both the first grille 2211 and the second grille 2221 are configured to extend along a straight line.

[0066] In this embodiment, the linear grating can be manufactured using standardized profiles, resulting in minimal material waste. Furthermore, the linear grating can be mass-produced through standardized processes such as stamping, extrusion, or injection molding, achieving a high yield rate without requiring complex molds or processing equipment.

[0067] Optionally, one of the first grille 2211 and the second grille 2221 is configured to extend along a straight line, and the other is configured to extend along an arc.

[0068] In this embodiment, the regular arrangement of straight-line grilles creates a simple and modern visual effect, while the curved design of the arc-shaped grilles softens the sharp angles of the space, increasing artistic flair and visual interest. The combination of arc-shaped and straight-line grilles enhances aesthetics. For example, the first grille 2211 extends along a straight line and is constructed as a straight-line grille. Simultaneously, the second grille 2221 extends along an arc and is constructed as an arc-shaped grille. Another example: the second grille 2221 extends along a straight line and is constructed as a straight-line grille. Simultaneously, the first grille 2211 extends along an arc and is constructed as an arc-shaped grille.

[0069] Optionally, both the first grille 2211 and the second grille 2221 are configured to extend along an arc, and the curvature of the first grille 2211 is equal to the curvature of the second grille 2221.

[0070] In this embodiment, because the curved grille itself has the characteristic of guiding airflow to diffuse along the curved surface, when the curvatures of the two grilles are equal, the diffusion trajectories of the airflow through the first grille opening 2212 and the second grille opening 2222 are similar, forming a uniform airflow field. Furthermore, grilles with the same curvature can be manufactured using materials of the same specifications, simplifying material selection and inventory management. Simultaneously, grilles with the same curvature can be produced using the same set of molds or processing techniques, reducing mold development costs and production cycle.

[0071] Optionally, both the first grille 2211 and the second grille 2221 are configured to extend along an arc, and the curvature center of the first grille 2211 and the curvature center of the second grille 2221 are located on the same side or opposite side.

[0072] In this embodiment, when the curvature center of the first grille 2211 and the curvature center of the second grille 2221 are located on the same side (e.g.) Figure 3 As shown), this allows the airflow from the first grille 2212 and the airflow from the second grille 2222 to form similar diffusion trajectories, thereby creating a uniform airflow field that facilitates the diffusion and flow of airflow to the surroundings. This is especially beneficial when the centers of curvature of the first grille 2211 and the second grille 2221 are located on opposite sides (e.g., Figure 5 As shown in the figure, the airflow blown out from the first gate 2212 and the airflow blown out from the second gate 2222 form opposite diffusion trajectories, thereby forming an interfering airflow field, which can be applied in some special scenarios.

[0073] Optionally, such as Figure 4 As shown, the top surface of the second shell 210 is constructed as a rectangle, and the center of the first ring coincides with the center of the rectangle. Furthermore, the distance between the outer ring of the first ring and the wide side of the adjacent rectangle is h1, and the distance between the outer ring of the first ring and the long side of the adjacent rectangle is h2, where 2≤h1 / h2≤6.

[0074] In this embodiment, the top surface of the rectangle provides a regular installation space for the first air outlet structure 220, and the center of the first ring coincides with the center of the rectangle, ensuring that the first air outlet structure 220 is located at the geometric center of the top surface, avoiding space waste caused by offset design. Furthermore, limiting the ratio of h1 / h2 to between 2 and 6 makes the first air outlet structure 220 closer to the longer side, thus reserving more space in the wider side direction. This space can be used to install other structures such as buttons and display screens.

[0075] Optionally, such as Figure 2 As shown, the side of the first housing 110 is provided with a second air outlet structure 230, which is used to outlet air toward the side of the sub-unit 200.

[0076] In this embodiment, a first air outlet structure 220 is provided on the top surface of the sub-unit 200 to achieve top surface air outlet, and a second air outlet structure 230 is provided on the side of the sub-unit 200 to achieve side air outlet. This dual air outlet design optimizes the airflow path, enabling the sub-unit 200 to be applied in more scenarios.

[0077] Optionally, the second air outlet structure 230 is disposed on the front side panel of the second housing 210. In this way, the sub-unit 200 can outlet air forward.

[0078] Optionally, the first air outlet structure 220 and the second air outlet structure 230 can supply air simultaneously or independently.

[0079] In this embodiment, the first air outlet structure 220 and the second air outlet structure 230 of the slave unit 200 can flexibly respond to different scenario requirements and improve adjustment efficiency by simultaneously or independently discharging air. For example, when the slave unit 200 is in a low-power state, only the first air outlet structure 220 (top air outlet) or the second air outlet structure 230 (side air outlet) can be activated to reduce unnecessary energy consumption and noise. When operating at full load, the first air outlet structure 220 and the second air outlet structure 230 are activated simultaneously to quickly adjust the indoor temperature and humidity.
