Description

Technical Field

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

[0002] In related technologies, the air outlet temperature of the indoor unit of an air conditioner can only be controlled by adjusting the temperature of the heat exchanger. This results in poor comfort when directly blowing cool or hot air, which is quite different from natural wind. Secondly, the indoor airflow becomes relatively dry after passing through the heat exchanger for cooling. Prolonged cooling leads to low indoor air humidity and poor comfort. Utility Model Content

[0006] According to an embodiment of this utility model, the indoor unit of an air conditioner is provided with a guiding air duct that connects to the air outlet channel through the casing. The guiding air duct has a connecting opening with opposing first and second edges. The second edge is located on the side of the duct wall where the first edge is located away from the air outlet channel, or on the side of the extended surface of the duct wall away from the air outlet channel. This allows air from the external environment to be introduced into the air outlet channel, regulating the humidity and temperature of the air outlet, thereby improving airflow comfort and the feeling of airflow. Furthermore, the panel can move relative to the casing, forming a guiding air duct between them. In the windless mode, the air outlet channel can discharge air through the air outlet, the guiding air duct, and the guiding air duct, increasing the airflow volume in the windless mode and further improving airflow comfort.

[0007] In some embodiments of this utility model, the air duct includes at least two air duct sections, any two adjacent air duct sections are connected, and the one of the air duct sections closest to the air outlet is the innermost air duct section. In the air duct direction, the width of the innermost air duct section gradually increases.

[0008] In some embodiments of this utility model, in the direction of airflow in the airflow duct, the maximum width of the remaining two airflow duct sections is less than the maximum width of the innermost airflow duct section.

[0045] The following is in conjunction with the appendix Figures 1 to 11 This describes an embodiment of the air conditioner indoor unit 100.

[0046] like Figures 1 to 3As shown, the indoor unit 100 of the air conditioner according to an embodiment of the present invention includes a housing 10 and a panel 20. The housing 10 is provided with an air outlet duct 101, an air outlet 102, and a diversion duct 103. The air outlet 102 is connected to the air outlet duct 101, and the air outlet duct 101 has a duct wall 1011. The diversion duct 103 is connected to the outside of the housing 10 and has a connecting opening 132 connecting to the duct wall 1011. The connecting opening 132 has a first edge 132a and a second edge 132b opposite to each other. The second edge 132b is positioned closer to the air outlet 102 than the first edge 132a. The second edge 132b is located on the side of the air duct wall 1011 where the first edge 132a is located, away from the air outlet 101, or on the side of the extension surface 1012 of the air duct wall 1011 away from the air outlet 101; the panel 20 is covered on the air outlet 102, and the panel 20 is configured to be movable relative to the housing 10 so that the panel 20 can be moved away from the housing 10, and a guide air duct 105 is formed between the panel 20 and the housing 10, and the guide air duct 105 is connected to the air outlet 102.

[0047] In the embodiments of the above scheme, depending on the different design requirements of the air conditioner indoor unit 100, the air duct wall 1011 of the air outlet duct 101 in the housing 10 can be set as, but is not limited to, a plane or a curved surface, etc.

[0048] refer to Figure 4 The first edge 132a and the second edge 132b can refer to the edge line of the connecting port 132, with the first edge 132a being farther away from the air outlet 102 and the second edge 132b being closer to the air outlet 102. The housing 10 is designed according to requirements, wherein the first edge 132a and the second edge 132b can be set as, but is not limited to, straight lines or curves, etc.

[0049] The connection port 132 can be located on the air outlet duct 101. That is, the first edge 132a and the second edge 132b can both be located on the duct wall 1011, and the second edge 132b is located on the side of the duct wall 1011 where the first edge 132a is located away from the air outlet duct 101.

[0050] The connecting port 132 can also be located at one end of the air outlet duct 101. That is, the first edge 132a is located on the duct wall 1011, while the second edge 132b is located on the side of the extension surface 1012 of the duct wall 1011 away from the air outlet duct 101 (see...). Figure 4 In this context, "the extended surface 1012 of the duct wall 1011" can refer to a surface that is extended or extended on the basis of the duct wall 1011 according to the original trend, and the extended surface 1012 can be, but is not limited to, a plane or a curved surface, etc.

[0051] It is understandable that, regardless of whether the second edge 132b is located on the side of the duct wall 1011 where the first edge 132a is located that is far from the air outlet 101, or on the side of the extension surface 1012 of the duct wall 1011 that is far from the air outlet 101, a height difference can be formed between the second edge 132b and the first edge 132a. The position of the second edge 132b can reduce the obstruction of the air outlet airflow. When the air outlet airflow passes through the second edge 132b of the connecting port 132, the airflow speed is faster and the airflow pressure is lower, which can further increase the induced draft negative pressure, so that the air in the external environment can be more easily introduced into the air outlet 101 from the induced draft duct 103, thereby improving the induced draft effect and the air outlet feel.

[0052] Optionally, the air duct 103 can be configured as one or more. For example, refer to... Figure 4 The air duct 103 can be configured as two, with a height difference H1 between the first edge 132a and the second edge 132b of the connecting port 132 of one of the two air ducts 103, and a height difference H2 between the first edge 132a and the second edge 132b of the connecting port 132 of the other.

[0053] When the indoor unit 100 of this utility model is heating or cooling, hot or cold air can be blown outward from the air outlet 102 through the air outlet 101. The indoor unit 100 can have at least an air outlet mode and a windless mode. In the air outlet mode ( Figure 3 This is a schematic diagram showing the indoor unit 100 of the air conditioner in air outlet mode. Figure 3 (The direction of the airflow is indicated by the middle arrow), the indoor unit 100 of the air conditioner can directly discharge air through the air outlet 102; in the windless mode ( Figure 5 This is a schematic diagram showing the indoor unit 100 of the air conditioner in windless mode. Figure 5 (The direction of the airflow is indicated by the middle arrow). The indoor unit 100 of the air conditioner can slowly expel air through the air outlet 102 to achieve a windless airflow.

[0054] refer to Figure 3In the air outlet mode of the indoor unit 100 of the air conditioner, the air velocity in the outlet duct 101 is generally relatively high. Since the casing 10 has a guide air duct 103, when air passes through the guide air duct 103, due to the high air velocity, the pressure inside the outlet duct 101 is relatively lower than the pressure inside the guide air duct 103. Therefore, a negative pressure zone is formed inside the outlet duct 101. Air from the external environment can enter the outlet duct 101 along the guide air duct 103 and mix with hot or cold air before being blown out from the air outlet 102. In this design, since a height difference can be formed between the second edge 132b and the first edge 132a of the connecting port 132, the guide air duct 103 has a better airflow effect. The air introduced from the external environment can better regulate the temperature and humidity of the air at the air outlet 102, improving the comfort of the airflow and resulting in a gentler and more pleasant airflow.

[0055] refer to Figure 5 In the windless mode of the indoor unit 100, the panel 20 can move relative to the casing 10. When air is emitted from the air outlet 102, the wind speed is relatively low and the airflow is relatively slow. Part of the airflow is blown out from the air outlet 102, another part is blown upward from the guide air duct 105 formed between the panel 20 and the casing 10, and a third part is blown out from the duct 103. In this way, while achieving slow airflow, the air volume and direction are increased, as well as the airflow range is expanded. This also makes the airflow gentler, the wind feel better, and improves the comfort of the airflow.

[0056] According to an embodiment of the present invention, the indoor unit 100 of the air conditioner is provided with a guide air duct 103 that connects to the air outlet duct 101 through the casing 10. The guide air duct 103 has a connecting opening 132, which has a first edge 132a and a second edge 132b. The second edge 132b is located on the side of the duct wall 1011 where the first edge 132a is located that is away from the air outlet duct 101, or on the side of the extension surface 1012 of the duct wall 1011 that is away from the air outlet duct 101. This allows air from the external environment to be introduced into the air outlet duct 101, adjusting the humidity and temperature of the air outlet, thereby improving the comfort and airflow. Moreover, the panel 20 can move relative to the casing 10, forming a guide air duct 105 between them. In the windless mode, the air outlet duct 101 can discharge air through the air outlet 102, the guide air duct 105, and the guide air duct 103, which can increase the airflow volume in the windless mode and also improve the comfort of the air outlet.

[0057] In some embodiments of this utility model, such as Figure 6As shown, the air diversion duct 103 includes at least two duct sections 131, any two adjacent duct sections 131 are connected, and the one of the at least two duct sections 131 that is closer to the air outlet duct 101 is the innermost duct section 1311. In the air diversion direction of the air diversion duct 103, the width of the innermost duct section 1311 gradually increases.

[0058] The airflow duct 103 may include multiple airflow sections 131, and the number of airflow sections 131 may be, but is not limited to, two, three, four, etc. The airflow section 131 closest to the air outlet duct 101 is designated as the innermost airflow section 1311. The "airflow direction of the airflow duct 103" may refer to the direction of the airflow duct 103 from the outside to the inside. Figure 6 The arrow inside the central air duct 10 points to the width of the innermost duct section 1311, which can refer to the air outlet direction parallel or approximately parallel to the air outlet duct 101. Figure 6 The dimensions indicated by the arrow inside the central air outlet duct 101.

[0059] In the above scheme, the innermost air duct section 1311 is shaped like a trumpet with a gradually increasing width. When the air outlet channel 101 can reach the set air speed (which can be understood as the air outlet air speed being relatively high at this time), the innermost air duct section 1311 with the above structure can form multiple negative pressure zones along the airflow direction of the air diversion channel 103. Moreover, the closer to the air outlet channel 101, the greater the negative pressure, which can drive the air in the air duct section 131 to quickly enter the innermost air duct section 1311, which is conducive to quickly introducing air into the air outlet channel 101 and can improve the air diversion effect of the air diversion channel 103.

[0060] In some embodiments of this utility model, in the direction of airflow in the airflow duct 103, the maximum width of the remaining two airflow duct sections 131 is smaller than the maximum width of the innermost airflow duct section 1311.

[0061] The width of the remaining air duct sections 131 in at least two of the air duct sections 131 can be equal or gradually varying (gradually decreasing or increasing along the airflow direction). Since the maximum width of the remaining air duct sections 131 in the airflow direction of the airflow duct 103 is smaller than the maximum width of the innermost air duct section 1311, the overall width of the airflow duct 103 gradually increases. Furthermore, the air duct sections 131 near the outer side of the housing 10 are relatively smaller than the innermost air duct section 1311, which helps to create a larger pressure difference between the innermost air duct section 1311 and the remaining air duct sections 131, driving air from the remaining air duct sections 131 to the innermost air duct section 1311, thereby improving the airflow effect.

[0062] In some embodiments of this utility model, the housing 10 has a target wall surface located on the outside of the housing 10. The air duct 103 penetrates the target wall surface and extends through the second edge 132b and is tangent to the air duct wall of the air duct 103. The angle between the extension surface and the target wall surface is less than 90 degrees.

[0063] The target wall can refer to one or more of the multiple walls of the housing 10. (See reference) Figure 6 The air duct 103 can be located on the upper side of the air outlet 102. In this case, the target wall surface can refer to the front wall surface 1041 of the housing 10. The extension surface that passes through the second edge 132b and is tangent to the duct wall of the air duct 103 can be denoted as the first extension surface O1. The included angle between the first extension surface O1 and the front wall surface 1041 can be denoted as β, where β is less than 90 degrees. Alternatively, the air duct 103 can be located on the lower side of the air outlet 102. In this case, the target wall surface can refer to the bottom wall surface 1042 of the housing 10. The extension surface that passes through the second edge 132b and is tangent to the duct wall of the air duct 103 can be denoted as the second extension surface O2. The included angle between the second extension surface O2 and the bottom wall surface 1042 can be denoted as α, where α is less than 90 degrees.

[0064] Or, refer to Figure 6 The air duct 103 is simultaneously located on the upper and lower sides of the air outlet 102. In this case, there can be two target walls, corresponding to the front wall 1041 and the bottom wall 1042 of the casing 10, respectively. Of course, this is just an example. There can be other examples of the number of air ducts 103 and the target walls, which will not be elaborated here.

[0065] In the above technical solution, since the angle between the extended surface and the target wall is less than 90 degrees, the connecting port 132 of the air diversion duct 103 can tilt towards the side closer to the air outlet 102 to discharge air. In this case, the air introduced by the air diversion duct 103 can be sent along the air outlet direction of the air outlet channel 101. That is, the airflow direction of the air introduced by the air diversion duct 103 and the airflow direction of the air outlet channel 101 can tend to be in the same direction, which can prevent the airflow in the air outlet channel 101 from flowing back to the connecting port 132 and ensure the air diversion effect of the air diversion duct 103. Moreover, the inclined setting of the air diversion duct 103 constructed above can play a guiding role, which is conducive to the air in the external environment entering the air diversion duct 103 along the air diversion duct 103.

[0066] In some embodiments of this utility model, such as Figures 3 to 6 As shown, there are at least two air ducts 103, including at least a first air duct 1031 and a second air duct 1032. The first air duct 1031 is located on the upper side of the air outlet 102 and between the housing 10 and the panel 20. The second air duct 1032 is located on the lower side of the air outlet 102.

[0067] refer to Figure 3 By setting up the first air duct 1031 and the second air duct 1032, the amount of air mixed in can be increased, improving the humidity and temperature regulation effect of the airflow and bringing a better airflow experience. Moreover, the first air duct 1031 can mix air on the upper side of the air outlet channel 101, and the second air duct 1032 can mix air on the lower side of the air outlet channel 101. By mixing air on both sides of the air outlet channel 101, the uniformity of airflow mixing can be improved, enhancing the mixing effect of airflow within the air outlet channel 101. This results in a more uniform temperature and humidity of the airflow from the air outlet 102, leading to a better airflow experience.

[0068] Secondly, refer to Figure 3 In the windless mode of the indoor unit 100 of the air conditioner, the first air duct 1031 and the second air duct 1032 can work together with the air outlet duct 101 to achieve air outlet. By setting the first air duct 1031 and the second air duct 1032, the air volume can be increased, the cooling or heating capacity during air conditioning can be increased, the wind feel experience of the windless mode can be improved, and a better windless effect can be brought.

[0069] In some embodiments of this utility model, such as Figure 6 As shown, the second air duct 1032 has a target air duct wall 10321 near the air outlet 102, and the portion of the target air duct wall 10321 near the air outlet 102 has an arc-shaped wall 10321a.

[0070] This can be understood as the arc-shaped wall 10321a forming a Coanda effect on the target air duct wall 10321, driving the introduced air in the second air duct 1032 to flow along the arc-shaped wall 10321a toward the air outlet 102, which can better draw air from the external environment to the air outlet 102 and improve the air intake effect.

[0071] In some embodiments of this utility model, the first air duct 1031, the second air duct 1032, and the housing 10 are integrally formed. In this technical solution, the first air duct 1031 and the second air duct 1032 are directly formed on the housing 10 during the housing 10 forming stage. This reduces the number of parts and assembly steps, simplifies the assembly process, improves assembly efficiency, and also enhances the stability of the first air duct 1031 and the second air duct 1032 on the housing 10, extending their service life.

[0072] In some embodiments of this utility model, such as Figure 3 As shown, the housing 10 includes: a housing body 11, a first air duct 12 and a second air duct 13. The housing body 11 is provided with an air outlet 101 and an air outlet 102. The first air duct 12 is provided on the housing body 11 and is provided with a first air duct 1031. The second air duct 13 is provided on the housing body 11 and is provided with a second air duct 1032.

[0073] In this technical solution, the first air duct 1031, the second air duct 1032 and the housing 10 are designed as separate structures. The first air duct 1031 is formed on the first air duct 12, and the second air duct 1032 is formed on the second air duct 13. The first air duct 12, the second air duct 13 and the housing body 11 are manufactured separately, which can reduce manufacturing difficulty and manufacturing cost.

[0074] In some embodiments of this utility model, such as Figure 3 , Figure 5 , Figure 8 and Figure 11 As shown, the main body 11 of the casing includes a front frame 111 and a chassis 112. The front frame 111 is mounted on the chassis 112 and forms an air outlet 101 and an air outlet 102. A first air duct 12 and a second air duct 13 are mounted on the front frame 111. The chassis 112 can be located at the rear of the front frame 111 for wall mounting. The first air duct 12 and the second air duct 13 are mounted on the front frame 111, which makes it easier to install and arrange the first air duct 12 and the second air duct 13.

[0075] In some embodiments of this utility model, such as Figures 1 to 5 , Figures 8 to 11 As shown, panel 20 is provided with first air vents 20a, and the first air vents 20a are arranged in an array on panel 20.

[0076] The first air vents 20a can be arranged in at least one row on the panel 20, with each row including multiple first air vents 20a. For example, the first air vents 20a are arranged in one row on the panel 20, and this row of first air vents 20a extends along the length of the panel 20. Figure 1 and Figure 2 Multiple air vents 20a are provided in the left and right directions; or, the first air vents 20a are arranged in multiple rows on the panel 20, with each row of first air vents 20a extending along the length of the panel 20. Figure 1 and Figure 2 There are multiple [locations] in the left and right directions.

[0077] In the above technical solution, the array of first air holes 20a can form a microporous structure on the panel 20. When the air blown out of the air outlet 102 passes through the panel 20, the air can be dispersed by the array of first air holes 20a to prevent the air from blowing directly on the user, which is conducive to achieving windless air outlet.

[0078] In some embodiments of this utility model, such as Figures 1 to 8 , Figure 11 As shown, the indoor unit 100 of the air conditioner also includes an air guide plate 30, which is movably disposed in the air outlet 102. The air guide plate 30 is provided with a second air hole 30a, and the second air hole 30a is arranged in an array on the air guide plate 30.

[0079] The second air vents 30a can be arranged in at least one row on the air guide plate 30, with each row including multiple second air vents 30a. For example, the second air vents 30a are arranged in one row on the air guide plate 30, and this row of second air vents 30a extends along the length of the air guide plate 30. Figure 1 and Figure 2 Multiple second air vents 30a are provided in the left and right directions; or, the second air vents 30a are arranged in multiple rows on the air guide plate 30, with each row of second air vents 30a extending along the length of the air guide plate 30. Figure 1 and Figure 2 There are multiple [locations] in the left and right directions.

[0080] This can be understood as follows: the air guide plate 30 can guide the air blown from the air outlet 102 away from its direct forward direction, preventing the air from blowing directly onto the user. For example, the air guide plate 30 can guide the air to the air duct 105, allowing some of the air to be blown out from the air duct 105 or from the first air hole 20a on the panel 20. Secondly, the second air holes 30a arranged in an array on the air guide plate 30 can disperse the air, preventing the air from blowing directly onto the user while allowing the air to slowly diffuse in front of the user, achieving a windless airflow effect. In other words, the air guide plate 30 and its second air holes 30a, as well as the panel 20 and its first air holes 20a, work together to improve the windless airflow effect.

[0081] In some embodiments of this utility model, such as Figure 5 and Figure 8 As shown, the indoor unit 100 of the air conditioner has a windless mode. When the indoor unit 100 of the air conditioner is in the windless mode, the panel 20 moves away from the casing 10 to form a guide air duct 105, and the air guide plate 30 moves to a set position. When the air guide plate 30 is in the set position, the surface of the air guide plate 30 forms an angle with the air outlet direction of the air outlet channel 101. Air outlet channel 101, guide air duct 105, first air duct 1031 and second air duct 1032 are used for air outlet.

[0082] The angle formed between the surface of the air guide plate 30 and the air outlet direction of the air outlet channel 101 can serve as a windbreak to prevent the air from the air outlet 102 from blowing directly on the user. At this time, part of the airflow in the air outlet channel 101 is dispersed and blown out from the second air hole 30a of the air guide plate 30, and another part flows to the air guide duct 105 under the guidance of the air guide plate 30 and is dispersed and blown out from the first air hole 20a of the panel 20. The rest of the airflow is blown out through the first air duct 1031 and the second air duct 1032. This method can achieve a windless air outlet effect and increase the air volume, which is beneficial to improving the airflow experience.

[0083] In some embodiments of this utility model, such as Figure 8As shown, the panel 20 can move away from the housing 10, and an airflow duct 103 is formed between the panel 20 and the housing 10. In this technical solution, the airflow duct 103 can be formed by the panel 20 moving and closing with the housing 10. This solution can reduce the number of parts, simplify the assembly process, improve assembly efficiency, and help reduce costs.

[0084] In some embodiments of this utility model, such as Figure 3 , Figure 4 , Figure 5 and Figures 9 to 11 As shown, panel 20 can at least cover the air outlet 102. In this technical solution, panel 20 can function to close the air outlet 102. When the indoor unit 100 of the air conditioner is in the off mode, panel 20 covers the air outlet 102 (see...). Figure 11 When the indoor unit 100 of the air conditioner is in the air outlet mode and the windless mode, the panel 20 can be moved to open the air outlet 102 (see...). Figure 3 and Figure 5 ).

[0085] In the above technical solution, the panel 20 can form an airflow duct 105 with the casing 10, which can guide the airflow in the windless mode and improve the windless experience. On the other hand, it can also serve as the switch for the air outlet 102. It can be seen that the panel 20 can achieve multiple uses, reduce the number of parts, reduce costs, and also help reduce assembly steps and improve assembly efficiency.

[0086] It should be noted that, as Figure 3 , Figure 5 , Figure 8 , Figure 11 As shown, the casing 10 also has an air inlet 106, which connects to the air outlet duct 101. The indoor unit 100 may also include a heat exchanger 40 and a fan wheel 50, which are located inside the casing 10. When the indoor unit 100 is working, the fan wheel 50 drives air from the outside environment through the air inlet 106 and through the heat exchanger 40. When the heat exchanger 40 is working, it can exchange heat with the passing air to form hot or cold air. The airflow after heat exchange can be directed to the outside through the air outlet 102 of the air outlet duct 101.

[0087] Specifically, the impeller 50 can be, but is not limited to, a cross-flow impeller and an axial flow impeller, etc. In addition, the air conditioning indoor unit 100 may also include other components, such as electrical control components and filter components. The composition and operation of the electrical control components and filter components are known to those skilled in the art and will not be described in detail here.

[0088] The air conditioner according to an embodiment of the present utility model includes the air conditioner indoor unit 100 described above.

[0089] According to the embodiment of the present invention, the air conditioner, by adopting an indoor unit 100, can introduce air from the external environment when it is venting, thereby adjusting the temperature and humidity of the venting airflow, improving the comfort and feel of the venting airflow, and thus enhancing the user experience of the air conditioner.

[0090] The air conditioner according to the embodiments of the present invention also includes an outdoor unit. Other components and operations of the outdoor unit are known to those skilled in the art and will not be described in detail here.
