Description

Technical Field

[0001] This disclosure relates to the field of air conditioner technology, and more particularly to an air conditioner. Background Technology

[0002] In air conditioners, the spatial arrangement of heat exchangers in the air inlet and outlet chambers where the fan is located has a crucial impact on the performance of the equipment.

[0003] When the distance from the fan outlet to the leftmost side of the heat exchanger is too small, the airflow blown out by the fan will directly impact the fins. This will not only cause uneven stress on the fins, accelerating fin wear and shortening the service life of the equipment, but will also cause the airflow to form a turbulent flow state on the fin surface, disrupting the normal heat exchange flow field and reducing heat exchange efficiency.

[0004] When this distance is set too large, on the one hand, the airflow from the fan will suffer from diffusion and resistance losses during transmission, resulting in a significant reduction in the air velocity reaching the heat exchanger surface. Insufficient air velocity will reduce the convective heat transfer coefficient between the air and the heat exchanger, reducing the amount of heat transferred per unit time and severely affecting the heat exchange effect. On the other hand, an excessive distance will occupy internal space of the equipment, directly affecting the size design of the air outlet on the same side as the air inlet.

[0005] In addition, excessively large air outlets can also lead to a series of adverse effects. Considering that there needs to be a certain distance between the air outlet and the heat exchanger, if the air outlet is too large, the size of the heat exchanger often needs to be reduced. A reduction in the size of the heat exchanger means a reduction in the heat exchange area. According to the principles of heat transfer, a reduction in the heat exchange area will directly weaken the heat exchange capacity between the heat exchanger and the air, thereby reducing the overall heat exchange effect.

[0031] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: In this disclosure, the air conditioner includes an air inlet cavity and an air outlet cavity. The air inlet cavity includes an air inlet, and the air outlet cavity includes a first air outlet. The air inlet and the first air outlet are located on the same side (e.g., the lower side) of the air conditioner, and the first air outlet is located in the air outlet cavity away from the air inlet cavity. A heat exchanger is disposed in the air outlet cavity. In the arrangement direction of the air inlet cavity and the air outlet cavity, the distance between the first edge of the heat exchanger and the second edge of the air inlet cavity is denoted as a first dimension, and the dimension of the air outlet cavity is denoted as a second dimension. The ratio of the first dimension to the second dimension is greater than or equal to the first dimension. The ratio of the size of the first air outlet to the size of the second air outlet is greater than or equal to 0.20 and less than or equal to 0.32.

[0032] Furthermore, an excessively large first air outlet shortens the distance between the return air source and the outlet air source, increasing the likelihood of coupling between them. This leads to noise superposition and resonance, increasing the noise generated during device operation and severely impacting the comfort and quietness of the user environment. However, this disclosure, by defining the relationship between the dimensions of the first air outlet in the first direction and the second dimension, as well as the relationship between the first and second dimensions, effectively avoids an excessively large first air outlet. This ensures sufficient distance between the return air source and the outlet air source, preventing noise superposition and resonance, improving the comfort and quietness of the user environment, and further enhancing the user experience.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0044] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure.

[0045] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application.

[0046] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0047] In order to solve the technical problem of poor heat exchange effect caused by spatial layout issues in the prior art, this disclosure provides an air conditioner.

[0048] In this disclosure, the air conditioner includes an air inlet cavity and an air outlet cavity. The air inlet cavity includes an air inlet, and the air outlet cavity includes a first air outlet. The air inlet and the first air outlet are located on the same side (e.g., the lower side) of the air conditioner, and the first air outlet is located in the air outlet cavity away from the air inlet cavity. A heat exchanger is disposed in the air outlet cavity. In the arrangement direction of the air inlet and air outlet cavities, the distance between the first edge of the heat exchanger and the second edge of the air inlet cavity is denoted as a first dimension, and the dimension of the air outlet cavity is denoted as a second dimension. The ratio of the first dimension to the second dimension is greater than or equal to 0.10 and less than or equal to 0.10. The ratio of the size of the first air outlet to the size of the second air outlet is greater than or equal to 0.20 and less than or equal to 0.32. This is to avoid the gap between the heat exchanger and the air inlet cavity being too large or too small, and also to avoid the first air outlet being too large or too small. This helps to better balance the relationship between the sizes of the first size, the second size, and the first air outlet, thereby achieving a more reasonable spatial layout, making the size of the heat exchanger more optimal, and improving the heat exchange effect of the entire air conditioner, thus enhancing the user experience.

[0049] Furthermore, an excessively large first air outlet shortens the distance between the return air source and the outlet air source, increasing the likelihood of coupling between them. This leads to noise superposition and resonance, increasing the noise generated during device operation and severely impacting the comfort and quietness of the user environment. However, this disclosure, by defining the relationship between the dimensions of the first air outlet in the first direction and the second dimension, as well as the relationship between the first and second dimensions, effectively avoids an excessively large first air outlet. This ensures sufficient distance between the return air source and the outlet air source, preventing noise superposition and resonance, improving the comfort and quietness of the user environment, and further enhancing the user experience.

[0050] In one exemplary embodiment, reference Figure 1-3 As shown, an air conditioner is provided, which may include an air inlet cavity 1 and an air outlet cavity 2. A fan 12 (e.g., a centrifugal fan 12) is disposed within the air inlet cavity 1, and a heat exchanger 23 is disposed within the air outlet cavity 2. The air inlet cavity 1 includes an air inlet 11, and the air outlet cavity 2 includes a first air outlet 21. The air inlet 11 and the first air outlet 21 are located on the same side of the air conditioner, and the first air outlet 21 is located in the air outlet cavity 2 away from the air inlet cavity 1. For example, the air inlet 11 and the first air outlet 21 are located on the lower side of the air conditioner, and are respectively located at two opposite edges of the air conditioner.

[0051] In the first direction, the distance between the first edge of the heat exchanger 23 and the second edge of the air inlet cavity 1 is denoted as the first dimension (i.e., Figure 1 The dimensions of the air outlet cavity 2 (N1) are denoted as the second dimension (i.e., Figure 1In N2), the ratio of the first dimension to the second dimension is greater than or equal to 0.10 and less than or equal to 0.20, and the dimension of the first air outlet 21 (i.e., Figure 1 The ratio of the middle dimension (M1) to the second dimension is greater than or equal to 0.20 and less than or equal to 0.32.

[0052] It should be noted that the first direction is the arrangement direction of the air inlet cavity and the air outlet cavity, the first edge of the heat exchanger 23 is the edge of the heat exchanger 23 near the air inlet cavity, and the second edge of the air inlet cavity 1 is the edge of the air inlet cavity 1 near the air outlet cavity 2.

[0053] In this embodiment, by limiting the ratio of the first dimension to the second dimension, the distance between the heat exchanger 23 and the first edge of the air inlet cavity 1 can be prevented from being too large or too small, ensuring that they are maintained at a suitable distance. This better ensures the uniformity of stress on the fins of the heat exchanger 23, better avoids fin wear, extends the service life of the equipment, and also prevents the airflow from forming a turbulent flow state on the fin surface, thus avoiding disruption of the normal heat exchange flow field. In other words, this embodiment can improve heat exchange efficiency. In addition, it can also avoid vibration and noise caused by airflow impacting the fins, improving the quietness and comfort of the operating environment. Moreover, since the maximum spacing dimension is limited, it can prevent the airflow velocity reaching the surface of the heat exchanger 23 from being too low due to excessive diffusion and excessive resistance loss during transmission. That is, this embodiment can ensure that the airflow discharged from the air inlet cavity still has a high velocity after reaching the heat exchanger 23, which can further improve the heat exchange effect. Moreover, by limiting the above dimensions, it can also prevent the setting of the size of the first air outlet 21 from being affected by the above spacing dimension being too large.

[0054] Furthermore, in this embodiment, by limiting the ratio of the size of the first air outlet 21 to the second size, the size of the first air outlet 21 can be prevented from being too large or too small, maintaining a suitable size that ensures the required airflow while preventing the first air outlet 21 from encroaching on the size of the heat exchanger 23 due to its excessive size. In other words, this embodiment, through the aforementioned limitations, ensures that the heat exchanger 23 has sufficient installation space and sufficient heat exchange area, thereby improving the heat exchange effect of the air conditioner.

[0055] It should be noted that, in this embodiment, the specific values ​​of the first dimension, the second dimension, and the dimension of the first air outlet 21 in the first direction are not limited, and can be set according to actual needs. For example, the first dimension is greater than or equal to 25mm and less than or equal to 40mm, the dimension of the first air outlet 21 in the first direction is greater than or equal to 55mm and less than or equal to 70mm, and the second dimension is greater than or equal to 220mm and less than or equal to 240mm.

[0056] This embodiment, by limiting the dimensions of the first dimension, the second dimension, and the first air outlet 21, can avoid the gap between the heat exchanger 23 and the air inlet cavity 1 being too large or too small, and can also avoid the first air outlet 21 being too large or too small. This avoids the gap between the first air outlet 21 and the air inlet 11 being too large or too small, and can better balance the relationship between the dimensions of the first dimension, the second dimension, and the first air outlet 21, thereby achieving a more reasonable spatial layout, making the dimensions of the heat exchanger 23 more optimal, better improving the heat exchange effect of the entire air conditioner, and enhancing the user experience.

[0057] Furthermore, an excessively large first air outlet 21 shortens the distance between the return air source and the outlet air source, increasing the likelihood of coupling between them. This leads to noise superposition and resonance, increasing the noise generated during device operation and severely impacting the comfort and quietness of the user environment. However, this disclosure, by defining the relationship between the dimensions of the first air outlet 21 in the first direction and the second dimension, as well as the relationship between the first and second dimensions, effectively avoids an excessively large first air outlet 21. This ensures sufficient distance between the return air source and the outlet air source, preventing noise superposition and resonance, improving the comfort and quietness of the user environment, and further enhancing the user experience.

[0058] In one exemplary embodiment, reference Figure 1-3 As shown, an air conditioner is provided. In this embodiment, in a first direction, the distance between the second edge of the heat exchanger 23 and the first edge of the first air outlet 21 is denoted as the third dimension (i.e., Figure 1 In N3), the ratio of the third dimension to the second dimension is greater than or equal to 0.07 and less than or equal to 0.12.

[0059] It should be noted that the second edge of the heat exchanger 23 is the edge of the heat exchanger 23 near the first air outlet 21, and the first edge of the first air outlet 21 is the edge of the first air outlet 21 near the heat exchanger 23.

[0060] The specific values ​​of the third and second dimensions mentioned above are not limited and can be set according to actual needs. For example, the second dimension can be greater than or equal to 220mm and less than or equal to 240mm, and the third dimension can be greater than or equal to 18mm and less than or equal to 25mm.

[0061] In this embodiment, by limiting the aforementioned third dimension, a reasonable transition space is provided for the airflow from the heat exchanger 23 to the first air outlet 21, thereby better ensuring airflow efficiency. Furthermore, it avoids the first air outlet 21 encroaching on the size of the heat exchanger 23, ensuring that the heat exchanger 23 has sufficient size and heat exchange area to better guarantee the heat exchange effect.

[0062] In one exemplary embodiment, reference Figure 1-3 As shown, an air conditioner is provided. In this embodiment, a second air outlet 22 is provided on the air outlet cavity 2, and the second air outlet 22 and the first air outlet 21 are located on different sides of the air outlet cavity 2. For example, the first air outlet 21 is a lower air outlet, and the second air outlet 22 is a side air outlet (also known as a front air outlet).

[0063] In the second direction, the size of the second air outlet 22 (i.e. Figure 2 The size of the air outlet cavity (i.e., H2) and H2) Figure 2 The ratio of H1) is greater than or equal to 0.45 and less than or equal to 0.70; wherein the second direction is perpendicular to the first direction, for example, the first direction is the left-right direction and the second direction is the up-down direction.

[0064] It should be noted that, in the second direction, the specific dimensions of the second air outlet 22 and the air outlet cavity are not limited and can be set based on actual needs. For example, the size of the air outlet cavity in the second direction can be 200mm, and the size of the second air outlet 22 in the second direction can be greater than or equal to 90mm and less than or equal to 140mm.

[0065] In this embodiment, by limiting the size of the second air outlet 22 and the size of the air outlet cavity, it can be ensured that the second air outlet 22 has sufficient air outlet size, thereby ensuring that the second air outlet 22 has sufficient air volume to better meet the user's needs. In addition, it can also avoid the second air outlet 22 being too large and affecting the structural stability of the entire air conditioner. That is, this embodiment can better meet the air outlet requirements of the second air outlet 22 while ensuring structural stability.

[0066] The air conditioner includes a first door panel 24 and a second door panel 25. The first door panel 24 and the second door panel 25 cooperate to close and open the second air outlet 22, and the second door panel 25 is used to open and close the first air outlet 21.

[0067] When the first air outlet 21 is in the open state and the second air outlet 22 is in the closed state, the first door panel 24 and the second door panel are both in the second position. The first door panel 24 and the second door panel 25 are arranged along the second direction and each door panel extends along the second direction, so that the first door panel 24 and the second door panel 25 close the first air outlet 21 and open the first air outlet 21.

[0068] When both the first air outlet 21 and the second air outlet 22 are open, the first door panel 24 is in the first position, and the second door panel 25 is located between the second position and the third position, with the angle between the second door panel 25 and the first direction (i.e., Figure 3a) greater than or equal to 25° and less than or equal to 55°.

[0069] It should be noted that in this embodiment, when the second door panel 25 closes the first air outlet 21, the second door panel 25 cannot close the second air outlet 22. That is, the area of ​​the second air outlet 22 corresponding to the second door panel 25 is in an open state. In other words, there must be an open air outlet between the first air outlet 21 and the second air outlet 22 to ensure the normal operation of the air conditioner.

[0070] In this embodiment, when both the first air outlet 21 and the second air outlet 22 are open, by limiting the angle between the second door panel 25 and the first direction, the air outlet effect of the first air outlet 21 and the second air outlet 22 can be better guaranteed, the air volume of the first air outlet 21 and the second air outlet 22 can be better balanced, and the user experience can be improved.

[0071] In addition, in this embodiment, a water receiving tray 26 is provided inside the air outlet cavity 2 to collect condensate generated inside the air outlet cavity 2. The two sides of the first air outlet 21 are provided with protrusions 211 that protrude from the air outlet cavity 2. The specific shape of the protrusions 211 is not limited, as long as they can guide the airflow from the first air outlet 21. The protrusions 211 are dimensional in the second direction (i.e., Figure 2 The ratio of H3 to the second dimension is greater than or equal to 0.06 and less than or equal to 0.09, so as to avoid the protrusion size of the protrusion 211 being too large or too small.

[0072] It should be noted that the dimensions of the protrusion 211 and the second dimension can be set according to actual needs, and their specific values ​​are not limited. For example, the second dimension can be greater than or equal to 220 mm and less than or equal to 240 mm, and the dimension of the protrusion 211 in the second direction can be greater than or equal to 15 mm and less than or equal to 20 mm, specifically, it can be 16 mm.

[0073] In this embodiment, by limiting the size of the protrusion 211, sufficient airflow can be guided from the first air outlet 21 to prevent backflow. Furthermore, it avoids affecting the overall size of the air conditioner due to excessive size. In other words, this embodiment can achieve sufficient airflow guidance from the first air outlet 21 while maintaining a small air conditioner volume.

[0074] In addition, a guide surface is provided on the side of the first air outlet 21 near the air inlet cavity. The tangent direction of the guide surface passing through the center of the first air outlet 21 forms an angle with the second direction. It should be noted that the guide surface has multiple tangents, among which the tangent passing through the center of the first air outlet 21 forms an angle with the second direction. This can guide at least part of the airflow from the first air outlet 21 to tilt towards the side away from the air inlet 11, so as to avoid mutual interference between the air outlet and the air inlet, further reduce the increase in noise generated during equipment operation, and better improve the comfort and quietness of the user environment.

[0075] In one exemplary embodiment, reference Figure 1-3 As shown, an air conditioner is provided. In this embodiment, the air conditioner includes an air inlet cavity 1 and an air outlet cavity 2. The air inlet cavity 1 includes an air inlet 11, and the air outlet cavity 2 includes a first air outlet 21. The air inlet 11 and the first air outlet 21 are located on the same side of the air conditioner, and the first air outlet 21 is located in the air outlet cavity 2 away from the air inlet cavity 1. A heat exchanger 23 is disposed inside the air outlet cavity 2. A second air outlet 22 is disposed on the air outlet cavity 2. The second air outlet 22 and the first air outlet 21 are located on different sides of the air outlet cavity 2. In addition, a water collection tray 26 is disposed inside the air outlet cavity 2, and protrusions 211 protruding from the air outlet cavity 2 are provided on both sides of the first air outlet 21.

[0076] In the first direction, the size of the air conditioner can be equal to the sum of the sizes of the air inlet cavity 1 and the air outlet cavity 2. For example, the size of the air conditioner in the first direction can be 450mm. In the first direction, the size of the air outlet cavity 2 can be greater than or equal to 220mm and less than or equal to 240mm. The distance between the first edge of the heat exchanger 23 and the second edge of the air inlet cavity 1 can be greater than or equal to 25mm and less than or equal to 40mm. The size of the first air outlet 21 in the first direction is greater than or equal to 55mm and less than or equal to 70mm. The distance between the second edge of the heat exchanger 23 and the first edge of the first air outlet 21 can be greater than or equal to 18mm and less than or equal to 25mm. Furthermore, the size of the second air outlet 22 in the second direction is greater than or equal to 90mm and less than or equal to 140mm.

[0077] The air outlet cavity 2 can have a dimension of 200mm in the second direction. A water receiving tray 26 is provided inside the air outlet cavity 2, and protrusions 211 protruding from the air outlet cavity 2 are provided on both sides of the first air outlet 21. The protrusions 211 have a dimension of greater than or equal to 15mm and less than or equal to 20mm in the second direction.

[0078] Additionally, the air conditioner includes a first door panel 24 and a second door panel 25. The first door panel 24 and the second door panel 25 cooperate to close and open the second air outlet 22, and the second door panel 25 is used to open and close the first air outlet 21. When both the first air outlet 21 and the second air outlet 22 are open, the first door panel 24 is in a first position, the second door panel 25 is located between the second position and the third position, and the angle between the second door panel 25 and the first direction is greater than or equal to 25° and less than or equal to 55°.

[0079] It should be noted that the first direction is the arrangement direction of the air inlet cavity and the air outlet cavity, the first edge of the heat exchanger 23 is the edge of the heat exchanger 23 near the air inlet cavity, the second edge of the air inlet cavity 1 is the edge of the air inlet cavity 1 near the air outlet cavity 2, the second edge of the heat exchanger 23 is the edge of the heat exchanger 23 near the first air outlet 21, the first edge of the first air outlet 21 is the edge of the first air outlet 21 near the heat exchanger 23, and the second direction is perpendicular to the first direction.

[0080] In this embodiment, by defining the dimensions and positions of the air inlet cavity 1, air outlet cavity 2, air inlet 11, first air outlet 21, second air outlet 22, heat exchanger 23, protrusion 211, and second door panel 25, sufficient space can be provided for the heat exchanger 23, ensuring it has a sufficient heat exchange area and thus improving the air conditioner's heat exchange effect and user experience. Furthermore, it better avoids interference between the air inlet and outlet, ensuring quietness and comfort of the air conditioner and further enhancing the user experience. Moreover, in this embodiment, because there is a sufficient distance between the air inlet 11 and the first air outlet 21, and a flow-guiding structure is provided at the first air outlet 21, air backflow and condensation can be avoided when cold air is flowing from the first air outlet 21.
