Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit and an air conditioning system. Background Technology

[0002] A wall-mounted air conditioner is a unit used to handle changes in air temperature within a space. Currently, wall-mounted air conditioners mainly use cross-flow fans to drive airflow, thereby exchanging the cooling or heating capacity of the air conditioner with the indoor air. However, traditional cross-flow fans operate at high speeds, and their fan blades cut through the air, resulting in airflow that creates staged impacts and wave-like irritations, accompanied by significant noise, which is detrimental to improving the user experience.

[0007] The main body is also provided with an air guide channel, which has a second air inlet and a second air outlet. The fan delivers airflow into the air guide channel through the second air inlet. The side wall of the air outlet channel is provided with a second air outlet, and the second air outlet faces the first air outlet.

[0008] Optionally, in one embodiment, the second air inlet is located on one side of the air outlet duct along a first direction, where the first direction is the length direction of the main body.

[0011] Optionally, in one embodiment, the main body is provided with a plurality of third air inlets, and the plurality of third air inlets are connected to the air cavity.

[0012] Optionally, in one embodiment, the main body has two main sidewalls that are spaced apart from each other;

[0013] At least one of the main sidewalls is provided with a first guide plate and a second guide plate. A first end of the first guide plate is connected to the main sidewall, and a second end of the first guide plate is spaced apart from the main sidewall. The first guide plate and the main sidewall enclose at least a portion of the air guiding channel. A first end of the second guide plate is connected to the main sidewall, and a second end of the second guide plate bypasses the second end of the first guide plate and extends in a direction toward the first exhaust port.

[0018] The air conditioner indoor unit provided in this application has a second exhaust vent facing the first exhaust vent on the side wall of the air outlet duct. By utilizing the airflow velocity difference between the second exhaust vent and the air outlet duct, an air pressure difference is generated, forming an airflow from inside the air outlet duct toward the first exhaust vent.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] This application provides an indoor air conditioning unit to address the problem of poor airflow experience for users of wall-mounted air conditioners with cross-flow fans. The following description, in conjunction with the accompanying drawings, will illustrate this.

[0034] In the embodiments of this application, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the indoor unit of the air conditioner includes:

[0035] The main body 1 is used for connection with the wall. The main body 1 has a through air outlet duct 11, with a first air inlet 111 and a first air outlet 112 at its two ends; and,

[0036] Fan 2 is located inside the main body 1;

[0037] The main body 1 is also provided with an air guide channel 12, which has a second air inlet 121 and a second air outlet 122. The fan 2 delivers airflow into the air guide channel 12 through the second air inlet 121. The side wall of the air outlet channel 11 is provided with a second air outlet 122, and the second air outlet 122 faces the first air outlet 112.

[0038] It should be noted that "main unit 1, for connection with the wall" refers to the indoor unit of the air conditioner being mounted on the wall, as opposed to a floor-standing indoor unit. The fan 2 can be a turbine fan, axial fan, etc., as long as it can generate airflow. For ease of description, the state of the indoor unit of the air conditioner in this application after it has been correctly installed on the wall is taken as a reference. The sidewall of the air outlet duct 11 can refer to the upper sidewall, lower sidewall, left sidewall, and right sidewall surrounding the air outlet duct 11, wherein at least one of the upper sidewall, lower sidewall, left sidewall, and right sidewall is provided with a second exhaust vent 122.

[0039] It is understandable that by setting an air guide channel 12 on the main body 1 and setting a second air outlet 122 on the side wall of the air outlet channel 11 facing the first air outlet 112, the airflow generated by the fan 2 is blown out from the side wall of the air outlet channel 11 (i.e., the second air outlet 122) and towards the first air outlet 112. Since wind speed and air pressure are negatively correlated, the vicinity of the second air outlet 122 and the position it passes through when blowing towards the first air outlet 112 have a larger wind speed but a smaller air pressure, while the position in the air outlet channel 11 far from the second air outlet 122 has a smaller wind speed but a relatively larger air pressure. The air pressure difference between different positions in the air outlet channel 11 guides the formation of airflow that flows sequentially through the first air outlet 112, the air outlet channel 11, and the second air outlet 122. This airflow has good continuity and flow stability, avoiding the staged airflow impact caused by the fan blades cutting the air in the related technology, and improving the user's experience.

[0040] Meanwhile, the fan 2 has a wider variety of options, such as cross-flow fans, axial flow fans, and turbine fans. In particular, when using a turbine fan, its high energy conversion efficiency not only ensures air volume but also saves installation space inside the main body 1.

[0041] Furthermore, current air conditioner indoor units are typically equipped with a gentle breeze unit. While this unit can simulate a natural breeze, it also results in a significant reduction in airflow. In contrast, this application utilizes a turbine fan to greatly increase airflow, allowing for the flexible installation of gentle breeze units with different structures, providing a variety of product options.

[0042] In some embodiments, such as Figure 2 and Figure 3 As shown, the second air inlet 121 is located on one side of the air outlet duct 11 along the first direction, which is the length direction of the main body 1.

[0043] It is understandable that in this application, after the indoor unit of the air conditioner is installed on the wall in the correct posture, the horizontal direction is the length direction of the main body 1, which is also the length direction of the indoor unit of the air conditioner. It is not difficult to imagine that the fan 2 is located at the left or right end of the air outlet duct 11, which is different from the position of the cross-flow fan in the indoor unit of the air conditioner in the related technology.

[0044] In some embodiments, such as Figure 3 As shown, there are two air guide channels 12, which are located on opposite sides of the air outlet channel 11.

[0045] It should be noted that, for ease of description, the state of the indoor unit of the air conditioner in this application after it has been installed on the wall in the correct posture is taken as a reference. The opposite sides of the air outlet duct 11 can refer to the upper and lower sides of the air outlet duct 11, or the left and right sides of the air outlet duct 11.

[0046] It is understandable that by using two relatively arranged air outlet channels 11, the second exhaust vents 122 of each of the two air outlet channels 11 are also relatively arranged on the opposite side walls inside the air outlet channels 11. This is conducive to forming a large-scale high-speed airflow inside the air outlet channels 11, thereby forming a uniformly distributed low-pressure area, increasing the pressure difference, and blowing a stable and sufficient amount of cold or warm air into the indoor space.

[0047] In some embodiments, such as Figure 4 , Figure 5 as well as Figure 6 As shown, the main body 1 is provided with one or more air cavities 13. The air cavities 13 are located on one or both sides of the air outlet channel 11 along the first direction. The air cavities 13 are connected to the second air inlet 121. The second air outlet 122 and the first air outlet 112 are both located in the second direction, and the second direction forms an angle with the first direction.

[0048] It should be noted that when air cavities 13 are provided on both sides of the air outlet duct 11 in the first direction, a fan 2 is provided in each air cavity 13. The angle formed between the second direction and the first direction means that the angle between the second direction and the first direction is not equal to 0 degrees and not equal to 180 degrees.

[0049] It is understandable that the airflow generated by the fan 2 is concentrated through the air cavity 13 to ensure that all the airflow is delivered to the air guide channel 12 through the second air inlet 121, thereby reducing wind energy loss and increasing wind pressure. By setting the second air inlet 121 and the second air outlet 122 in different directions, a smaller fan 2 can be used, and setting the fan 2 on one or both sides of the air outlet channel 11 along the first direction helps to save installation space inside the main body 1.

[0050] Furthermore, when the main body 1 is provided with a wind cavity 13, the wind cavity 13 is connected to the second air inlet 121 of the two air guide channels 12, and the two air guide channels 12 are respectively provided on the upper and lower sides of the air outlet channel 11.

[0051] Alternatively, when the main unit 1 is equipped with two air chambers 13, the two air chambers 13 are located on both sides of the air outlet duct 11 in the first direction, and each air chamber 13 is equipped with a fan 2. Two air guide channels 12 are respectively located on the upper and lower sides of the air outlet duct 11, and two second air inlets 121 are respectively connected to the two air chambers 13. In this way, the airflow in the two air guide channels 12 can be increased, thereby increasing the amount of cooling or heating air in the indoor unit of the air conditioner. Furthermore, since the second air inlets 121 and the second exhaust outlets 122 of the air guide channels 12 are not located in the first direction, the two fans 2 located on both sides of the air outlet duct 11 in the first direction can effectively improve the problem of the small distribution of low-pressure areas in the air outlet duct 11 and their concentration on the side closer to the air outlet duct 11 in the first direction.

[0052] In some embodiments, such as Figure 7 As shown, the main body 1 is provided with multiple third air inlets 14, which are connected to the air cavity 13.

[0053] Understandably, multiple third air inlets 14 ensure that the fan 2 can draw in sufficient air and convert it into a sufficient, high-speed airflow.

[0054] In some embodiments, such as Figure 3 As shown, the main body 1 has two main side walls 15 that are arranged at relatively intervals;

[0055] At least one main sidewall 15 is provided with a first guide plate 16 and a second guide plate 17. The first end of the first guide plate 16 is connected to the main sidewall 15, and the second end of the first guide plate 16 is spaced apart from the main sidewall 15. The first guide plate 16 and the main sidewall 15 enclose each other to form at least a portion of the air guide channel 12. The first end of the second guide plate 17 is connected to the main sidewall 15, and the second end of the second guide plate 17 bypasses the second end of the first guide plate 16 and extends in the direction toward the first exhaust port 112. The second guide plate 17 and the first guide plate 16 enclose each other on the side away from the main sidewall 15 to form at least a portion of the air guide channel 12 and the second exhaust port 122.

[0056] It should be noted that, in the above description, the positions of the first drainage plate 16 and the second drainage plate 17 are set with reference to the main side wall 15 directly connected to them.

[0057] A complete airflow channel 12 is formed by the first guide plate 16, the second guide plate 17, and the main sidewall 15. It is easy to deduce that at least a portion of the first guide plate 16 and at least a portion of the second guide plate 17 constitute at least a portion of the sidewall of the air outlet channel 11. The two main sidewalls 15 can be the upper and lower sidewalls in the aforementioned embodiments, or the left and right sidewalls in the aforementioned embodiments. The second end of the second guide plate 17 bypassing the second end of the first guide plate 16 means that a portion of the second guide plate 17 is located on the side of the first guide plate 16 facing the main sidewall 15, and another portion is located on the side of the first guide plate 16 away from the main sidewall 15.

[0058] Understandably, when the airflow generated by the fan 2 flows through the air guide duct 12, it needs to be turned at the second end of the second guide plate 17, which bypasses the first guide plate 16. This allows the second exhaust vent 122 to be positioned in the air outlet duct 11 away from the first exhaust vent 112. On the one hand, this helps guide indoor air from the first air inlet 111 into the air outlet duct 11. On the other hand, it helps to create a large area of ​​low pressure in the air outlet duct 11 near the heat exchanger of the indoor unit of the air conditioner. This avoids the second exhaust vent 122 being too close to the first exhaust vent 112, which would result in a small low pressure area in the first exhaust vent 112 and poor airflow due to pressure difference in the air outlet duct 11.

[0059] Furthermore, such as Figure 6 As shown, along the first direction, one end of the main sidewall 15 and one end of the first guide plate 16 extend into the air cavity 13 and enclose it to form the second air inlet 121. The sidewall of the air cavity 13 blocks the gap between the first guide plate 16 and the second guide plate 17 to prevent the airflow in the air cavity 13 from flowing out directly from the second exhaust port 122.

[0060] Furthermore, the size of the air cavity 13 is larger than the size of the second air inlet 121. By reducing the size of the second air inlet 121, the flow velocity within the air guide channel 12 is increased.

[0061] In some embodiments, such as Figure 3 As shown, both main sidewalls 15 are provided with a first diversion plate 16 and a second diversion plate 17. The side of the two first diversion plates 16 facing each other is set as an arc surface, and the distance between the two first diversion plates 16 gradually increases along the direction close to the first exhaust port 112.

[0062] Understandably, based on the wall attachment effect, the airflow from the second exhaust vent 122 will flow along the first guide plate 16 with an arc surface, rather than moving in a straight line away from the arc surface. This is beneficial for controlling the airflow direction and expanding the low-pressure area.

[0063] In some embodiments, such as Figure 3As shown, the second end of the first drainage plate 16 is bent in the direction close to the main sidewall 15.

[0064] It should be noted that the bending of the second end of the first drainage plate 16 in the direction close to the main sidewall 15 means that the cross section of the second end of the first drainage plate 16 in the direction perpendicular to the first direction presents a hook shape.

[0065] Understandably, since the airflow will turn between the second end of the first guide plate 16 and the second guide plate 17, the high-speed airflow will continuously impact the second guide plate 17. Based on this, the airflow is guided to the connection between the main side wall 15 and the second guide plate 17 by the bending of the second end of the first guide plate 16, and then the airflow is guided to flow along the surface of the second guide plate 17, thereby extending the service life of the second guide plate 17 and reducing the vibration and corresponding noise caused by the continuous impact on the second guide plate 17.

[0066] In some embodiments, such as Figure 3 As shown, the size of at least a portion of the air guide channel 12 formed by the second guide plate 17 and the first guide plate 16 is smaller than the size of at least a portion of the air guide channel 12 formed by the first guide plate 16 and the main sidewall 15.

[0067] It is understandable that by reducing the size of the air guide channel 12 near the second exhaust port 122, the airflow velocity from the second exhaust port 122 is increased, further increasing the pressure difference at different locations within the exhaust channel 11, and accelerating the air intake and exhaust of the exhaust channel 11.

[0068] This application also provides an air conditioning system, which includes the above-mentioned indoor unit and outdoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since this air conditioning system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.
