Description

Technical Field

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

[0002] In air conditioners that use cross-flow fans, the core design of the volute is to create an eccentric vortex inside the cross-flow fan blades. The strength of the eccentric vortex determines the stability of the airflow and the outlet flow rate, and the volute tongue is a key component that affects the strength and stability of the eccentric vortex.

[0003] In related technologies, such as Figure 1 As shown, the volute is designed such that the transition profile from the volute tongue to the tail is a tapering profile. The gap a0 between the volute tongue and the cross-flow fan blade is larger than the gap b0 between the tail and the cross-flow fan blade, causing the airflow to be gradually forced into the interior of the cross-flow fan blade, thus forming an eccentric vortex. However, this volute structure leads to excessive backflow of airflow in this section, resulting in a significant decrease in the outlet airflow rate. Utility Model Content

[0004] This application provides an indoor air conditioning unit and an air conditioner to at least solve the technical problem that in the volute structure of air conditioners currently using cross-flow fans, the transition line from the volute tongue to the tail of the volute section is a tapering line, resulting in excessive airflow returning from the volute section and a significant decrease in the outlet airflow.

[0005] According to a first aspect of the embodiments of this application, an air conditioner indoor unit is provided, the air conditioner indoor unit comprising: The casing has an air inlet and an air outlet; A volute assembly is disposed within the housing. The volute assembly includes an air inlet end and an air outlet end. The air inlet end is connected to the air inlet port, and the air outlet end is connected to the air outlet port. The volute assembly includes a volute and a rotatable cross-flow fan blade disposed within the volute. The volute includes a first volute located on one side of the cross-flow fan blade in the radial direction. The first volute includes a first shell section and a second shell section. The first shell section includes a head near the air outlet and a tail away from the air outlet. The head forms the volute tongue of the volute assembly. The gap between the first shell section and the cross-flow fan blade gradually increases from the head to the tail. The second shell section is located at the tail. The minimum gap between the second shell section and the cross-flow fan blade is smaller than the gap between the tail and the cross-flow fan blade.

[0006] In this embodiment, by gradually increasing the gap between the first casing section and the cross-flow fan blade from the head to the tail, a smaller gap is formed between the volute tongue and the cross-flow fan blade. This reduces the flow of air ejected from the volute into the expanding space between the first volute and the cross-flow fan blade, effectively increasing the outlet air volume. Furthermore, by setting a second casing section at the tail of the first volute, and forming a smaller gap between the second casing section and the cross-flow fan blade, some of the airflow in the expanding space can flow back into the cross-flow fan blade. This allows the cross-flow fan blade to form a stable eccentric vortex near the first volute, effectively improving the outlet air stability of the volute and enhancing the heat exchange effect.

[0007] In conjunction with the first aspect, in an optional embodiment of the present application, the second shell segment includes an inner guide wall, the inner guide wall includes an arc-shaped wall, the concave surface of the arc-shaped wall faces the head, and the end of the arc-shaped wall away from the tail forms the minimum gap with the cross-flow fan blade.

[0008] In conjunction with the first aspect, in an optional embodiment of the present application, the second shell segment is a hook-shaped structure connected to the tail, and the inner guide wall is formed on the inner side of the hook portion of the hook-shaped structure.

[0009] In conjunction with the first aspect, in an optional embodiment of this application, the gap between the head and the cross-flow fan blade is a, and the minimum gap between the second shell section and the cross-flow fan blade is b, satisfying that b is less than or equal to a.

[0010] In conjunction with the first aspect, in an optional embodiment of this application, the value of a ranges from 3mm to 7mm; And / or, the value of b ranges from 3mm to 7mm.

[0011] In conjunction with the first aspect, in an optional embodiment of this application, the first shell section is further provided with an overflow hole, which is disposed close to the second shell section; And / or, the second shell section (32) is provided with an overflow hole.

[0012] In conjunction with the first aspect, in an optional embodiment of this application, there are multiple overflow holes, and the multiple overflow holes are spaced apart along the axial direction of the cross-flow fan blade.

[0013] In conjunction with the first aspect, in an optional embodiment of the present application, the housing includes a front housing, the first volute is disposed close to the front housing, the air outlet is located below the front housing, and an outer guide wall is formed at the lower end of the front housing corresponding to the air outlet. The first volute also includes a third shell segment, which is located below the first shell segment and connected to the head. The third shell segment extends from the head toward the air outlet and docks with the outer guide wall.

[0014] In conjunction with the first aspect, in an optional embodiment of the present application, the volute assembly further includes a second volute, which is located on opposite sides of the first volute in the radial direction of the cross-flow fan blade, and the second volute is integrally formed with the housing.

[0033] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following implementation methods and examples can be combined with each other.

[0034] This embodiment proposes an air conditioner indoor unit. The air conditioner indoor unit in this embodiment can be a wall-mounted air conditioner indoor unit or a cabinet air conditioner indoor unit. As long as the indoor unit adopts a volute assembly with cross-flow fan blades 2 and a volute, it falls within the protection scope of this utility model.

[0035] Reference Figure 2 and Figure 3The indoor unit of the air conditioner includes a housing 1 and a volute assembly, wherein: The housing 1 is provided with an air inlet 11 and an air outlet 12. In this embodiment, the positions of the air inlet 11 and the air outlet 12 are not specifically limited and can be flexibly designed according to requirements. In a specific example, such as... Figure 2 As shown, the air inlet 11 is located at the upper part of the housing 1, and the air outlet 12 is located at the lower part of the housing 1.

[0036] The volute assembly is housed within the housing 1. The volute assembly includes an air inlet end and an air outlet end. The air inlet end communicates with the air inlet 11, and the air outlet end communicates with the air outlet 12. The volute assembly includes a volute and a rotatable cross-flow fan blade 2 housed within the volute. The volute includes a first volute 3 located on one radial side of the cross-flow fan blade 2. The first volute 3 can be positioned near the front or rear of the housing 1, depending on the location of the air outlet 12. (Refer to...) Figure 1 The air outlet 12 is located at the lower part of the housing 1, and the first volute 3 is located near the front side of the housing 1.

[0037] Reference Figure 2 The volute assembly also includes a second volute 6, which is located on opposite sides of the first volute 3 opposite to the cross-flow fan blade 2. The second volute 6 is integrally formed with the housing 1, and the second volute 6 forms the air outlet profile of the volute. The airflow ejected by the cross-flow fan blade 2 can flow along the second volute 6 to the air outlet 12. (Refer to...) Figure 3 The airflow path diagram.

[0038] In other possible implementations, the second volute 6 can also be set independently of the housing 1 and fixed within the housing 1 by one or more of the following methods: snap-fit, plug-in, adhesive, or connector connection.

[0039] The first volute 3 includes a first shell segment 31 and a second shell segment 32. The first shell segment 31 includes a head 311 near the air outlet end and a tail 312 away from the air outlet end. The head 311 forms the volute tongue of the volute assembly.

[0040] Reference Figure 4 and Figure 5The gap between the first shell section 31 and the cross-flow fan blade 2 gradually increases from the head 311 to the tail 312. The first shell section 31 is a gradually expanding shape relative to the cross-flow fan blade 2, forming a gradually expanding space 301 between the first shell section 31 and the cross-flow fan blade 2. A smaller gap is formed between the volute tongue and the cross-flow fan blade 2. The airflow entering the volute assembly from the air inlet 11 moves towards the air outlet 12 inside the volute under the action of the cross-flow fan blade 2. When passing the volute tongue, most of the airflow flows towards the air outlet 12, while a small portion flows back into the gradually expanding space 301 through the gap between the volute tongue and the cross-flow fan blade 2. When the gap between the volute tongue and the cross-flow fan blade 2 is small enough, it can effectively prevent excessive airflow thrown out by the cross-flow fan blade 2 from flowing into the gradually expanding space 301, thereby effectively avoiding the problem of attenuation of the outlet airflow and increasing the outlet air volume.

[0041] The second shell section 32 is located at the tail section 312. The minimum gap between the second shell section 32 and the cross-flow fan blade 2 is smaller than the gap between the tail section 312 and the cross-flow fan blade 2, thus forming a smaller gap between the tail end of the gradually expanding space 301 and the cross-flow fan blade 2.

[0042] Reference Figure 3 , Figure 6 and Figure 8 The airflow within the gradually expanding space 301 comes partly from the airflow directly thrown in by the cross-flow fan blades 2 (refer to...). Figure 6 and Figure 8 (The airflow direction indicated by arrow e in the image) On the other hand, the airflow comes from the gap between the volute tongue and the cross-flow fan blade 2 (see reference). Figure 6 and Figure 8 (The airflow direction indicated by the middle arrow a) When the airflow reaches the second shell section 32 (refer to...) Figure 6 and Figure 8 (Airflow direction indicated by arrow b) Due to the small gap between the second shell section 32 and the cross-flow fan blade 2, the airflow is obstructed, and some airflow overflows from the gap between the second shell section 32 and the cross-flow fan blade 2 (refer to...). Figure 6 and Figure 8 (As indicated by arrow d in the diagram, the airflow direction is as follows), another portion of the airflow changes direction and returns to the interior of the cross-flow fan blade 2 (refer to...). Figure 6 and Figure 8 (The airflow direction is indicated by arrow c in the diagram). Figure 3 The airflow path diagram shows that, under the action of the second shell section 32, the airflow forms a stable eccentric vortex between the first volute 3 and the cross-flow fan blade 2, thereby improving the stability of the airflow from the volute assembly. It should be noted that the gap between the cross-flow fan blade 2 and the volute tongue, and the minimum gap between the cross-flow fan blade 2 and the second shell section 32 referred to in this embodiment are respectively the radial gap between the outer edge of the cross-flow fan and the volute tongue, and the radial gap between the outer edge of the cross-flow fan and the second shell section 32.

[0043] In one alternative implementation, refer to Figures 2-6 The second shell section 32 includes an inner guide wall, which includes an arc-shaped wall. The concave surface of the arc-shaped wall faces the head 311. The end of the arc-shaped wall away from the tail 312 forms a minimum gap with the cross-flow fan blade 2. The arc-shaped wall can guide more of the airflow flowing to the tail 312 of the first shell section 31 into the interior of the cross-flow fan blade 2, further improving the stability of the eccentric vortex.

[0044] In a preferred embodiment, the second shell section 32 is a hook-shaped structure connected to the tail section 312, and the inner guide wall is formed on the inner side of the hook portion of the hook-shaped structure. This embodiment achieves enhanced eccentric vortex stability by providing a hook-shaped structure at the tail section 312, while also offering the advantages of simple structure and low manufacturing cost.

[0045] In one alternative implementation, refer to Figure 4 The gap between the head section 311 and the cross-flow fan blade 2 is a, and the minimum gap between the second shell section 32 and the cross-flow fan blade 2 is b, satisfying that b is less than or equal to a. Without affecting the rotation of the cross-flow fan blade 2, the airflow in the gradually expanding space 301 can be effectively reduced from overflowing from the gap between the second shell section 32 and the cross-flow fan blade 2, thereby allowing more airflow to flow back into the cross-flow fan blade 2, further enhancing the stability of the eccentric vortex.

[0046] When the cross-flow fan blade 2 is rotating, the airflow pressure on the side of the second shell section 32 facing the expanding space 301 is higher, while the airflow pressure on the side away from the expanding space 301 is lower. Influenced by the suction force of the cross-flow fan blade 2 on the back side of the first shell section 31, the airflow within the expanding space 301 escapes through the gap between the second shell section 32 and the cross-flow fan blade 2, forming an overflow. This overflow is crucial for the overall stability of the machine. The larger the gap between the second shell section 32 and the cross-flow fan blade 2, the stronger the overflow, resulting in lower pressure inside the eccentric vortex, a larger eccentric vortex volume, and therefore poorer eccentric vortex stability. Conversely, the smaller the gap between the second shell section 32 and the cross-flow fan blade 2, the weaker the overflow, the stronger the pressure inside the eccentric vortex, a smaller eccentric vortex volume, and stronger eccentric vortex stability. Therefore, the value of b should be minimized as much as possible within the limits of structural design.

[0047] In a preferred embodiment, the value of a ranges from 3mm to 7mm; and / or, the value of b ranges from 3mm to 7mm.

[0048] In one alternative implementation, refer to Figure 7 The first shell section 31 is also provided with an overflow hole 313, which is located near the second shell section 32; and / or, the second shell section 32 is provided with an overflow hole 313. Preferably, there are multiple overflow holes 313, which are spaced apart along the axial direction of the cross-flow fan blade 2.

[0049] Due to the influence of the filter screen at the air inlet 11 and the indoor heat exchanger 5 inside the casing 1, there is a problem of high inlet resistance of the volute. The flow rate of the cross-flow fan 2 into the expanding space 301 will decrease, and the flow within the expanding space 301 will weaken. The airflow velocity inside the expanding space 301 also affects the stability of the eccentric vortex. Therefore, by opening an overflow hole 313 near the tail 312 of the first shell section 31 and / or opening an overflow hole 313 in the second shell section 32, the airflow flowing from the expanding space 301 to the second shell section 32 can overflow to the outside of the second shell section 32 (refer to...). Figure 8 (The airflow direction indicated by arrow f in the diagram) thereby increases the airflow velocity within the expanding space 301, allowing sufficient airflow to be ejected from the cross-flow fan blade 2 enclosed by the first volute 3, without forming a state of airflow intake. Furthermore, the cross-flow fan blade 2 can still form a strong eccentric vortex near the first volute 3, avoiding the problem of decreased stability of the eccentric vortex due to increased inlet resistance of the volute assembly.

[0050] Reference Figure 8 After adding the overflow hole 313, the airflow can flow from the expanding space 301 into the side of the second shell section 32 away from the expanding space 301, and return to the interior of the cross-flow fan 2 under the suction of the cross-flow fan blade 2 (see reference). Figure 8 (The airflow direction is indicated by arrow g in the diagram). At this point, the presence of the overflow hole 313 increases the outflow of air inside the cross-flow fan blade 2, thereby creating a more stable eccentric vortex on the side of the first volute 3, further improving the stability of the airflow exiting the volute. Simultaneously, it avoids the surge problem caused by a decrease in airflow rate when the cross-flow fan blade 2 is thrown into the expanding space 301 due to increased resistance.

[0051] In one alternative implementation, refer to Figure 2 The housing 1 includes a front housing, a first volute 3 located near the front housing, an air outlet 12 located below the front housing, and an outer guide wall 4 formed at the lower end of the front housing corresponding to the air outlet 12. The first volute 3 also includes a third housing section 33 located below the first housing section 31 and connected to the head 311. The third housing section 33 extends from the head 311 toward the air outlet 12 and connects with the outer guide wall 4. The outer guide wall 4 is used to guide the airflow from the volute to flow out toward the front of the housing 1, thereby improving the heat exchange effect in the room.

[0052] This embodiment also proposes an air conditioner, which includes the indoor unit provided in the first aspect of this application. This embodiment can improve the air volume and air supply stability, thereby improving the indoor heat exchange effect.

[0053] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
