Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an air inlet panel and an air conditioner. Background Technology

[0002] As an important household appliance for regulating indoor temperature and air quality, the air supply performance of air conditioners directly affects user comfort. Among them, the size of the intake air volume is one of the key factors determining the heat exchange efficiency and airflow circulation effect of air conditioners.

[0003] However, some existing air conditioners have structural design flaws such as limited air intake channels, insufficient air intake area, or excessive air intake resistance, resulting in a small overall air intake volume that cannot meet the needs of rapid cooling or heating, seriously affecting the user's comfort experience. Utility Model Content

[0004] The purpose of this utility model is to provide an air intake panel and an air conditioner, which has multiple air inlets, thus having good air intake performance, improving air intake efficiency and air outlet effect, and thereby enhancing user comfort.

[0005] The embodiments of this utility model are implemented as follows: In a first aspect, this utility model provides an air inlet panel, comprising: Front panel, wherein the front panel is provided with a first air inlet; Side panel, which is connected to the side of the front panel, and the side panel is provided with a second air inlet; A base plate, which is connected to the bottom of the front plate, and the base plate is provided with a third air inlet; The front panel includes multiple horizontally arranged panels, the side panels are connected to the ends of the multiple panels, the bottom panel is connected to the panel located at the bottom, and two adjacent panels are spaced apart to form the first air inlet.

[0006] In the above embodiments, by setting a first air inlet, a second air inlet, and a third air inlet on the front panel, side panel, and bottom panel respectively, multi-directional air intake paths are achieved. This not only diversifies the air intake paths structurally but also effectively increases the overall air intake area, thereby improving air intake efficiency. Therefore, by setting air inlets in different locations, the air conditioner can maintain good air intake performance in various installation environments, thereby improving air intake efficiency and air outlet effect, and ultimately enhancing user comfort. The front panel is composed of multiple horizontally arranged panels, which are evenly spaced to form a first air inlet between adjacent panels, thus enabling smooth airflow. This not only ensures the structural stability of the air intake panel but also increases the air intake area, thereby improving air intake efficiency.

[0007] In an optional embodiment, the front panel further includes a first air guide wall, one end of which is connected to the top of the panel, and the other end of which extends on the inner side of the front panel toward the side adjacent to the panel.

[0008] In the above embodiment, the first air guide wall is connected to the plate to form an airflow guiding channel. The first air guide wall extends from the inside of the front plate toward the side where the adjacent plate is located, which can effectively allow the airflow to flow smoothly along its surface into the space inside the air conditioner, so as to effectively guide the airflow.

[0009] In an optional embodiment, one end of the first air guide wall is connected to the top of the plate, and the other end extends vertically upward along the plate that is away from the plate and adjacent to it on the upper side.

[0010] In the above embodiment, since the air inlet panel is located in the lower half of the air conditioner and the upper shell, which serves as the air outlet panel, is located in the upper half of the air conditioner, the air guide wall extends from the plate body toward the interior and vertically upward toward the adjacent plate body. The first air guide wall can effectively guide the airflow smoothly along its surface to the upper space inside the air conditioner, thereby effectively guiding the airflow and ensuring that the airflow direction through the first air inlet is consistent. This not only effectively reduces the air intake resistance and improves the airflow capacity, but also reduces airflow turbulence, thereby improving the efficiency of the subsequent heat exchange process.

[0011] In an optional embodiment, the first air guide wall has an inwardly concave arc surface.

[0012] In the above embodiments, the concave arc-shaped first air guide wall can provide a smoother and more natural flow path for the airflow during the guiding process, thereby enabling the airflow to flow more smoothly along the surface of the first air guide wall, thus reducing the local resistance encountered by the airflow during the flow process. In addition, it can effectively suppress the turbulence of the airflow, thereby improving the stability and consistency of the air intake.

[0013] In an optional embodiment, the top of the first air guide wall is at a lower horizontal height than the bottom of the adjacent plate.

[0014] In the above embodiment, the projection of the first air guide wall on the front plate is within the outline of the first air inlet, and the projection height of the first air guide wall on the front plate is lower than the outline of the first air inlet, so that the top of the first air guide part and the bottom of the adjacent plate form a height difference, thereby optimizing the initial flow path of the air intake, reducing the local resistance when the air intake enters, and improving the air intake efficiency.

[0015] In an optional embodiment, the front plate further includes a connecting rib, one end of which is connected to the top of the first air guide wall, and the other end is connected to the adjacent plate body.

[0016] In the above embodiments, by setting connecting ribs in the front panel and forming a stable connection structure between the top of the first air guide wall and the panel body, the load-bearing capacity and deformation resistance of the air guide wall can be significantly improved without increasing the overall structural complexity. This results in the air inlet panel having good structural integrity and functional stability, thereby extending the product's service life and improving overall performance.

[0017] In an optional embodiment, there are two side panels, which are respectively connected to both sides of the front panel, and the front panel, the side panels, and the bottom plate are integrally formed.

[0018] In the above embodiment, the two side panels are respectively connected to the two sides of the front panel and can be manufactured by a one-piece molding process. This not only simplifies the process and reduces costs, but also eliminates the need for additional connecting structures between the three components. This not only improves the overall sealing and rigidity of the structure, but also reduces assembly steps and increases production efficiency.

[0019] Secondly, this utility model provides an air conditioner, including a base, an upper shell, a rear cover, and an air inlet panel as described in any of the foregoing embodiments. The top end of the air inlet panel is connected to the upper shell, and the bottom end is connected to the base. The rear cover is disposed on the base and is connected to both the upper shell and the air inlet panel. The upper shell is provided with an air outlet.

[0020] In the above embodiment, the air intake panel serves as the air intake component at the front end of the air conditioner. Its top end is connected to the upper shell, and its bottom end is connected to the base, so that the entire air intake panel forms a stable support structure in the vertical direction and establishes a firm installation relationship with the upper shell and the base.

[0021] In an optional embodiment, the base is provided with a second air guide wall, which forms an air inlet channel with the base plate, and the second air guide wall is in the shape of an inwardly concave arc surface.

[0022] In the above embodiment, the second air guide wall is concave arc-shaped. This shape design creates a locally convergent airflow channel in space, which can effectively reduce the flow resistance of the airflow before entering the internal heat exchange area and improve the uniform distribution characteristics of the airflow, thereby improving the air intake efficiency.

[0023] In an optional embodiment, the air conditioner further includes a dust filter disposed on the inside of the air inlet panel.

[0024] In the above embodiments, the dust filter is located on the inside of the air intake panel, which enhances the air conditioning unit's ability to filter impurities in the outside air while ensuring the air intake volume, thereby improving the overall operational stability of the unit and helping to extend the service life of the air conditioning unit.

[0025] The beneficial effects of the air inlet panel and air conditioner provided in this embodiment of the utility model include: the front panel, as the main structural component of the air inlet panel, has a first air inlet for receiving airflow from the front of the air conditioner, providing the main air source for the heat exchanger; the side panel is connected to the side of the front panel, and a second air inlet is provided thereon, allowing the air conditioner to introduce external airflow from the side, which can effectively compensate for the limited airflow at the front, and the side airflow can serve as a supplementary path, further ensuring the stability and sufficiency of the airflow; moreover, a third air inlet is provided on the bottom plate, which is connected to the bottom of the front panel, thereby forming an air inlet channel in the bottom area, allowing airflow to flow from the bottom of the air conditioner. The air intake is designed to fully utilize the spatial structure to achieve multi-directional air intake. Furthermore, the front panel consists of multiple horizontally arranged panels, evenly spaced to form the first air intake between adjacent panels, ensuring smooth airflow. This design not only maintains the structural stability of the air intake panel but also increases the air intake area, thereby improving air intake efficiency. It is evident that by setting multiple air intakes on the front, side, and bottom panels, the air intake panel effectively enhances the overall air intake capacity and optimizes the air intake path distribution without significantly altering the air conditioner's external dimensions. This represents a significant improvement over traditional air intake structures in terms of structural design, resulting in a substantial enhancement of air conditioner performance and user experience.

[0035] As an important household appliance for regulating indoor temperature and air quality, the air supply performance of air conditioners directly affects user comfort. Among them, the size of the intake air volume is one of the key factors determining the heat exchange efficiency and airflow circulation effect of air conditioners.

[0036] However, some existing air conditioners have structural design flaws such as limited air intake channels, insufficient air intake area, or excessive air intake resistance, resulting in a small overall air intake volume that cannot meet the needs of rapid cooling or heating, seriously affecting the user's comfort experience.

[0037] Therefore, it is urgent to optimize the air intake structure of air conditioners to increase the effective air intake area, reduce air intake resistance, and improve the stability and sufficiency of air intake volume, thereby improving heat exchange efficiency and air delivery performance, improving indoor airflow organization, enhancing user comfort and satisfaction during use, and meeting the dual demands of modern air conditioning products for high performance and high comfort.

[0038] Please see Figures 1 to 5 This utility model provides an air inlet panel 100, which is suitable for electrical equipment such as air conditioners 10. The air inlet panel 100 has multiple air inlets, thus having good air intake performance, improving air intake efficiency and air outlet effect, and thereby improving user comfort.

[0039] In detail, the air intake panel 100 includes a front panel 110, a side panel 120, and a bottom panel 130.

[0040] It should be noted that there are two side panels 120, which are connected to both sides of the front panel 110 respectively. They can be made using an integral molding process, which is not only simple and low-cost, but also eliminates the need for additional connecting structures between the three components. This not only improves the overall sealing and rigidity of the structure, but also reduces assembly steps and increases production efficiency.

[0041] The front panel 110 is provided with a first air inlet 111, the side panel 120 is connected to the side of the front panel 110 and is provided with a second air inlet 121, the bottom panel 130 is connected to the bottom of the front panel 110 and is provided with a third air inlet 131.

[0042] As can be seen, by setting the first air inlet 111, the second air inlet 121, and the third air inlet 131 on the front panel 110, side panel 120, and bottom panel 130 respectively, multi-directional air intake paths are achieved. This not only diversifies the air intake paths structurally but also effectively increases the overall air intake area, thereby improving air intake efficiency. Therefore, by setting air inlets in different locations, the air conditioner 10 can maintain good air intake performance in various installation environments, thereby improving air intake efficiency and air output effect, and ultimately enhancing user comfort.

[0043] Specifically, the front panel 110, as the main structural component of the air intake panel 100, has a first air intake 111 for receiving airflow from the front of the air conditioner 10, providing the main air intake source for the heat exchanger; the side panel 120 is connected to the side of the front panel 110, and a second air intake 121 is provided on it, so that the air conditioner 10 can introduce external airflow from the side, which can effectively compensate for the limited air intake at the front, and the side air intake can serve as a supplementary path to further ensure the stability and sufficiency of the air intake volume; in addition, a third air intake 131 is provided on the bottom plate 130, which is connected to the bottom of the front panel 110, thereby forming an air intake channel in the bottom area, allowing airflow to enter from the bottom of the air conditioner 10, making full use of the space structure to achieve multi-directional air intake.

[0044] In summary, the air intake panel 100 provided in this embodiment of the present invention effectively improves the overall air intake capacity and optimizes the distribution of the air intake path by setting multiple air inlets on the front panel 110, side panel 120 and bottom panel 130, without significantly changing the external dimensions of the air conditioner 10. This achieves an improvement over the traditional air intake structure in terms of structural design and significantly enhances the performance and user experience of the air conditioner 10.

[0045] Furthermore, the front panel 110 includes a plurality of horizontally arranged panels 112, the side panel 120 is connected to the ends of the plurality of panels 112, the bottom panel 130 is connected to the panel 112 located at the bottom, and two adjacent panels 112 are spaced apart to form a first air inlet 111.

[0046] In this embodiment, the front panel 110 is composed of a plurality of horizontally arranged plates 112. The plurality of plates 112 are arranged at equal intervals to form a first air inlet 111 between two adjacent plates 112, thereby enabling smooth airflow. This not only takes into account the structural stability of the air inlet panel 100, but also increases the air inlet area, thereby improving air inlet efficiency.

[0047] Furthermore, the front panel 110 also includes a first air guide wall 113. One end of the first air guide wall 113 is connected to the top of the panel 112, and the other end extends on the inner side of the front panel 110 toward the side where the adjacent panel 112 is located, so as to form an airflow guiding channel, which can effectively allow the airflow to flow smoothly along its surface into the space inside the air conditioner 10, so as to play an effective guiding role for the airflow.

[0048] Specifically, one end of the first air guide wall 113 is connected to the top of the plate 112, and the other end extends vertically upward along the plate 112 that is away from the plate 112 and adjacent to it on the upper side.

[0049] Since the air inlet panel 100 is located in the lower half of the air conditioner 10 and the upper shell 300, which serves as the air outlet panel, is located in the upper half of the air conditioner 10, the air guide wall extends vertically upward from the plate 112 toward the interior and toward the adjacent plate 112. The first air guide wall 113 can effectively guide the airflow smoothly along its surface to the upper space inside the air conditioner 10, thereby effectively guiding the airflow and ensuring that the airflow direction through the first air inlet 111 is consistent. This not only effectively reduces the air intake resistance and improves the airflow capacity, but also reduces airflow turbulence, thereby improving the efficiency of the subsequent heat exchange process.

[0050] It can be understood that there are multiple first air guide walls 113, that is, a first air guide wall 113 is provided at the first air inlet 111 formed between every two adjacent plates 112.

[0051] It should be noted that the first air guide wall 113 has an inwardly concave arc surface.

[0052] It is understandable that the concave arc-shaped first air guide wall 113 can provide a smoother and more natural flow path for the airflow during the guiding process, thereby allowing the airflow to flow more smoothly along the surface of the first air guide wall 113, thus reducing the local resistance encountered by the airflow during the flow process. In addition, it can also effectively suppress the turbulence of the airflow, thereby improving the stability and consistency of the air intake.

[0053] It is also worth mentioning that the top of the first air guide wall 113 is at a lower horizontal height than the bottom of the adjacent plate 112.

[0054] In other words, the projection of the first air guide wall 113 on the front plate 110 is within the outline of the first air inlet 111, and the projection height of the first air guide wall 113 on the front plate 110 is lower than the outline of the first air inlet 111, so that the top of the first air guide part and the bottom of the adjacent plate 112 form a height difference, thereby optimizing the initial flow path of the incoming airflow, reducing the local resistance when the airflow enters, and improving the air intake efficiency.

[0055] Furthermore, the front panel 110 also includes a connecting rib 114, one end of which is connected to the top of the first air guide wall 113, and the other end is connected to the adjacent panel 112.

[0056] In this embodiment, the connecting rib 114 serves as a connector between the first air guide wall 113 and the plate 112, as well as a structural reinforcement component, which can improve the overall structural strength and stability of the front plate 110.

[0057] Therefore, by setting connecting ribs 114 in the front panel 110 and forming a stable connection structure between them and the top of the first air guide wall 113 and the plate 112, the load-bearing capacity and deformation resistance of the air guide wall can be significantly improved without increasing the overall structural complexity. This results in the air inlet panel 100 having good structural integrity and functional stability, thereby extending the product's service life and improving overall performance.

[0058] Further, please refer to Figure 6 This utility model embodiment also provides an air conditioner 10, including a base 200, an upper shell 300, a rear cover 400, and an air inlet panel 100 as described above. The top end of the air inlet panel 100 is connected to the upper shell 300, and the bottom end is connected to the base 200. The rear cover 400 is disposed on the base 200 and is connected to both the upper shell 300 and the air inlet panel 100. The upper shell 300 is provided with an air outlet 310.

[0059] In this embodiment, the air inlet panel 100 serves as the air inlet component at the front end of the air conditioner 10. Its top end is connected to the upper shell 300, and its bottom end is connected to the base 200, so that the entire air inlet panel 100 forms a stable support structure in the vertical direction and forms a firm installation relationship with the upper shell 300 and the base 200.

[0060] Furthermore, the base 200 is provided with a second air guide wall 210, which forms an air intake channel with the base plate 130, and the second air guide wall 210 is in the shape of an inwardly concave arc surface.

[0061] Specifically, the second air guide wall 210 has an inwardly concave arc shape. This shape design creates a locally converging airflow channel in space, which can effectively reduce the flow resistance of the airflow before entering the internal heat exchange area and improve the uniform distribution characteristics of the airflow, thereby improving the air intake efficiency.

[0062] In addition, the air conditioner 10 also includes a dust filter (not shown). The dust filter is located on the inside of the air inlet panel 100, which enhances the air conditioning unit's ability to filter impurities in the outside air while ensuring the air intake volume. This improves the overall stability of the unit's operation and helps to extend the service life of the air conditioner 10.

[0063] In summary, this utility model provides an air inlet panel 100 and an air conditioner 10. The front panel 110, as the main structural component of the air inlet panel 100, has a first air inlet 111 for receiving airflow from the front of the air conditioner 10, providing the main air source for the heat exchanger. The side panel 120 is connected to the side of the front panel 110 and has a second air inlet 121 on it, allowing the air conditioner 10 to introduce external airflow from the side, effectively compensating for the limited airflow at the front. The side airflow can serve as a supplementary path, further ensuring the stability and sufficiency of the airflow. Furthermore, a third air inlet... Air vent 131 is set on bottom plate 130, which is connected to the bottom of front plate 110, thus forming an air intake channel in the bottom area, allowing airflow to enter from the bottom of air conditioner 10 and making full use of the space structure to achieve multi-directional air intake; it can be seen that by setting multiple air inlets on front plate 110, side plate 120 and bottom plate 130 respectively, air intake panel 100 effectively improves the overall air intake capacity and optimizes the distribution of air intake path without significantly changing the external size of air conditioner 10, thus realizing an improvement over the traditional air intake structure in structural design and significantly improving the performance and user experience of air conditioner 10.

[0064] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
