Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a volute assembly and an air conditioner. Background Art

The centrifugal fan shell structure includes a volute, a volute tongue and an adjustment mechanism. The volute defines an installation cavity and an air outlet channel extending from one side of the installation cavity. The volute tongue extends toward the center of the air outlet channel and is protruding. At least part of the volute tongue is retractable in its protruding direction. The adjustment mechanism is used to adjust the retractable and adjustable part of the volute tongue. The power monitoring device is used to monitor the motor power parameters of the centrifugal fan. The control device is used to control the action of the adjustment mechanism according to the obtained motor power parameters, thereby adapting to different working conditions.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] Related technologies address the uneven airflow distribution along the volute's axial direction and high aerodynamic noise by controlling the expansion and contraction of the volute tongue. Both extension and retraction of the volute tongue rely on an adjustment mechanism, which results in long operating times, high energy consumption, and a short lifespan.

[0038] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0039] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A, or B, or A and B.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0041] Combine Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a volute assembly, including a volute 10 and an adjusting device 20.

[0042] The volute 10 defines a mounting cavity 102 for mounting the fan 30 and an air outlet passage 101 downstream of the mounting cavity 102. The adjustment device includes an elastic member 201 disposed in the air outlet passage 101 to adjust the flow area of ​​the air outlet passage 101 by expanding or contracting the elastic member 201. The elastic member can be disposed at various locations in the air outlet passage, as long as the expansion or contraction of the elastic member changes the flow area of ​​the air outlet passage 101.

[0043] Taking the volute assembly as an example, an air conditioner includes a connected indoor unit and outdoor unit. The indoor unit comprises a housing, a volute assembly, an indoor heat exchanger, and a fan 30. The housing defines an air duct, within which the volute assembly and indoor heat exchanger are located. The fan 30 is located within a mounting cavity 102, and the air outlet duct 101 is connected to the air duct. Under the action of the fan 30, air enters the air duct through the air inlet, exchanges heat with the indoor heat exchanger, and then flows out through the air outlet duct 101 and the air outlet of the air duct, achieving normal operation of the air conditioner.

[0044] By adjusting the elastic member 201 to extend or contract, the flow area of ​​the air outlet channel 101 can be changed, thereby varying air outlet parameters such as the air outlet area, air outlet angle, and air outlet speed, thereby avoiding problems such as a single air outlet angle and high aerodynamic noise. The flow area refers to the cross-sectional area of ​​the air passing through the air outlet channel 101.

[0045] The elastic member 201 is used to adjust the flow area of ​​the air outlet channel 101. Since the elastic member 201 has the ability to automatically reset, only one direction of movement of the elastic member 201 in the extension and retraction directions requires external force, and the movement in the other direction can be achieved by the automatic reset of the elastic member 201, which reduces the energy consumption of the adjustment device and improves the life of the adjustment device.

[0046] Alternatively, as Figure 1 and Figure 2As shown, the adjustment device also includes an outer frame 202, and the elastic member 201 is provided on the outer frame 202, which is used to drive the outer frame 202 to deform and drive the outer frame 202 to move between an extended position and a retracted position extending into the air outlet channel 101 to change the flow area of ​​the air outlet channel 101; wherein, in the retracted position, the shielding area of ​​the air outlet channel 101 by the outer frame 202 is smaller than the shielding area of ​​the air outlet channel 101 by the outer frame 202 in the extended position.

[0047] The side wall of the air outlet channel 101 is provided with a mounting notch, and the outer frame 202 is provided at the mounting notch. The outer frame 202 is formed into a ring, and the elastic member 201 is provided inside the outer frame 202. When the elastic member 201 is deformed, the outer frame 202 is driven to deform as well. The deformation direction of the elastic member 201 is toward or away from the central axis of the air outlet channel 101. Thus, when the elastic member 201 is deformed, the outer frame 202 is driven to move in a direction extending into or away from the air outlet channel 101. In this way, the outer frame 202 blocks different areas of the air outlet channel 101 in different positions, thereby changing the flow area of ​​the air outlet channel 101. Under the elastic force of the elastic member 201, the outer frame 202 repeatedly moves between the retracted position and the extended position, thereby changing the air outlet parameters of the air outlet channel 101, such as the air outlet area, air outlet direction, air outlet speed, and other air outlet parameters, thereby achieving more comfortable air supply.

[0048] In the retracted position, the outer frame 202 blocks a smaller area of ​​the air outlet channel 101 than in the extended position. Thus, the outer frame 202 blocks different areas of the air outlet channel 101 in the retracted and extended positions. From the retracted position to the extended position, the outer frame 202 moves closer to the central axis of the air outlet channel 101, extending into the air outlet channel 101 and blocking part or all of the air outlet channel 101. From the second extended position to the retracted position, the outer frame 202 moves away from the central axis of the air outlet channel 101, reducing the area it blocks from the air outlet channel 101 or completely withdrawing from the air outlet channel 101, thereby not blocking the air outlet channel 101.

[0049] The elastic member 201 is made of a material capable of elastic deformation, such as a spring or a spring sheet, so that the elastic member 201 has a telescopic deformation effect, which reduces the energy consumption of the regulating device and increases the life of the regulating device. Figure 1 In the example, taking the elastic member 201 as a coil spring, the deformation direction of the elastic member is the direction of the arrow M, and the length direction of the coil spring cannot be along the left-right direction.

[0050] Optionally, the outer frame 202 is an elastic outer frame 202 .

[0051] The outer frame 202 defines a mounting space for the elastic member 201, and the elastic member 201 is disposed within the mounting space. The outer frame 202 is constructed of an elastic material so that elastic deformation of the elastic member 201 causes the circumference of the outer frame 202 to change. Specifically, the outer frame 202 deforms in response to the deformation of the elastic member 201, preventing damage to the outer frame 202 due to deformation of the elastic member 201.

[0052] The elastic outer frame 202 can be made of rubber or silicone material that can undergo elastic deformation, which has a simple manufacturing process and saves costs.

[0053] Optionally, the extended position includes multiple sub-extended positions, i.e., the extended position includes multiple different sub-extended positions. At different sub-extended positions, the outer frame 202 covers different areas of the air outlet duct 101. The adjustment device also includes a driving member, which is drivingly connected to the elastic member 201 and is used to drive the elastic member 201 to extend and retract, and to drive the outer frame 202 to switch between the different sub-extended positions and the retracted position.

[0054] At different extension positions, the outer frame 202 has different shielding areas for the air outlet channel 101 , so that the air outlet channel 101 has different air outlet parameters, which can adapt to different usage requirements of users.

[0055] The outer frame 202 has a plurality of sub-extended positions and retracted positions. When the driving member is driven, the elastic member 201 has different extension and contraction amounts, thereby driving the outer frame 202 to be in different sub-extended positions or retracted positions.

[0056] The driving member may be a motor, and the motor may be a linear motor.

[0057] Optionally, there are multiple regulating devices, and the multiple regulating devices are sequentially arranged along the circumference of the air outlet channel 101. Figure 1 In the embodiment, the number of regulating devices is three.

[0058] Different adjustment devices will have different effects after operation, so the position of one or more middle and outer frames 202 in the adjustment device can be controlled so that the air outlet channel 101 can achieve more air outlet parameters, thereby achieving more air outlet effects.

[0059] The plurality of adjustment devices are sequentially arranged along the length direction of the cross section of the air outlet channel 101 , so that the plurality of adjustment devices can work in coordination to achieve more diversified air outlet parameters of the air outlet channel 101 .

[0060] Alternatively, as Figure 1 In the embodiment, the plurality of adjusting devices include a first adjusting device 203 , a second adjusting device 204 and a third adjusting device 205 .

[0061] The first adjusting device 203 is arranged in the middle of the length direction of the cross section of the air outlet channel 101; the second adjusting device 204 and the third adjusting device 205 are respectively arranged on the opposite sides of the first adjusting device 203, that is, the first adjusting device 203 is installed between the second adjusting device 204 and the third adjusting device 205.

[0062] The first regulating device 203, the second regulating device 204 and the third regulating device 205 are sequentially arranged along the length direction of the transverse surface of the air outlet channel 101. This can change the air outlet area in the length direction of the cross section of the air outlet channel 101 and the air outlet parameters such as the air outlet speed of each area, making the adjustment of the air outlet area more effective.

[0063] When the outer frame 202 of the first adjusting device 203 is in the extended position, the air outlet mode on both sides (i.e., the left and right sides) of the length direction of the air outlet channel 101 can be realized; when the outer frame 202 of the second adjusting device 204 is in the extended position, the air outlet mode on one side (for example, the right side) of the length direction of the air outlet channel 101 can be realized; when the outer frame 202 of the third adjusting device 205 is in the extended position, the air outlet mode on one side (for example, the left side) of the length direction of the air outlet channel 101 can be realized.

[0064] like Figure 1 As shown, the first regulating device 203 , the second regulating device 204 and the third regulating device 205 are all disposed at the upper end of the air outlet channel 101 .

[0065] According to a second aspect of an embodiment of the present invention, an air conditioner is provided, comprising a volute assembly as described in any one of the above embodiments; a fan 30 is disposed in the volute 10 .

[0066] The air conditioner provided by the embodiment of the second aspect of the present invention includes the volute assembly as described in any one of the above embodiments, and thus has all the beneficial effects of the volute assembly as described in any one of the above embodiments, which will not be repeated here.

[0067] Optionally, the air conditioner further includes a controller, which is connected to the multiple adjustment devices and is used to control the operation of one or more of the multiple adjustment devices to change the operation mode of the air conditioner.

[0068] The controller can change the air outlet parameters of the air outlet channel 101 by controlling the regulating device, thereby changing the air conditioning operation mode.

[0069] Optionally, the multiple gear extension positions include a first gear extension position and a second gear extension position, and the shielding area of ​​the air outlet channel 101 by the outer frame 202 at the first gear extension position is smaller than the shielding area of ​​the air outlet channel 101 by the outer frame 202 at the second gear extension position.

[0070] The operation mode of the air conditioner includes a silent operation mode. The controller is configured to: in the silent operation mode, control the first adjustment device 203, the second adjustment device 204 and the third adjustment device 205 to be in the first gear extended position.

[0071] The operation mode includes a self-cleaning mode, and the controller is configured to: in the self-cleaning mode, control the first adjustment device 203, the second adjustment device 204 and the third adjustment device 205 to be in the second gear extended position.

[0072] The operation mode includes a high-efficiency operation mode of the fan 30 , and the controller is configured to: in the high-efficiency operation mode of the fan 30 , control the first adjustment device 203 and the third adjustment device 205 to be in the first gear extended position and control the second adjustment device 204 to be in the retracted position.

[0073] Controlling different adjustment devices enables different operating modes of the air conditioner. Taking the second adjustment device 204 positioned to the left of the first adjustment device 203 and the third adjustment device 205 positioned to the right of the first adjustment device 203 as an example, the various operating modes are described. In the first position, the outer frame 202 extends into the air outlet duct 101 to a height approximately one-quarter of the height of the air outlet duct 101. In the second position, the outer frame 202 extends into the air outlet duct 101 to a height approximately one-half of the height of the air outlet duct 101.

[0074] Example 1: The first adjustment device 203, the second adjustment device 204 and the third adjustment device 205 are all not operating, that is, the outer frames 202 of the first adjustment device 203, the second adjustment device 204 and the third adjustment device 205 are all in the retracted position, the outer frame 202 does not block the air outlet channel 101 or the blocking area of ​​the air outlet channel 101 is small, the upper end of the air outlet channel 101 remains almost horizontal, the fan 30 operates normally, and the air outlet direction is the entire length direction of the air outlet channel 101 (that is, full-position air outlet), which is suitable for ordinary application environments.

[0075] Example 2: When the outer frame 202 of the second adjustment device 204 is in the second gear extended position and the first adjustment device 203 and the third adjustment device 205 are not in operation (that is, the outer frames 202 of the first adjustment device 203 and the third adjustment device 205 are both in the retracted position), the space on the left side of the air outlet channel 101 is compressed. When the airflow is blown out from the air outlet channel 101, it is blocked on the left side and blown out from the right side, achieving the purpose of right-side air outlet, thereby realizing the right-side air outlet mode of the air conditioner.

[0076] Example three, when the outer frame 202 of the third adjustment device 205 is in the second gear extended position and the first adjustment device 203 and the second adjustment device 204 are not in operation (that is, the outer frames 202 of the first adjustment device 203 and the second adjustment device 204 are both in the retracted position), the space on the right side of the air outlet channel 101 is compressed, and when the air flow is blown out from the air outlet channel 101, it is blocked on the right side and blown out from the left side, achieving the purpose of left-side air outlet, thereby realizing the left-side air outlet mode of the air conditioner.

[0077] Example 4: the outer frame 202 of the first adjustment device 203 is in the second gear extended position, the second adjustment device 204 and the third adjustment device 205 are not in operation (that is, the outer frames 202 of the second adjustment device 204 and the third adjustment device 205 are both in the retracted position), and the air inlet space in the middle of the air outlet channel 101 is compressed. When the airflow is blown out from the air outlet channel 101, it encounters an obstruction in the middle and is blown out from the left and right sides, achieving the purpose of left and right air outlet, thereby achieving the purpose of not blowing the air directly on people and blowing the air comfortably, thereby realizing a comfortable air supply mode.

[0078] Example 5: When the outer frames 202 of the second regulating device 203 and the third regulating device 205 are both in the first gear extended position and the first regulating device 203 is not in operation, the fan 30 is operating normally and the volute assembly is in the rectification high-efficiency operation mode. Due to the simulation flow field analysis, the maximum wind speed position of the volute 10 outlet is in the middle of the air outlet channel 101, and the air volume on both sides has a large area of ​​uneven wind speed bands. Therefore, appropriate adjustment to reduce the outlet of the volute 10 can make the air supply system operate with the highest efficiency. Adjust the second regulating device 204 and the third regulating device 205 to make the air supply system operate with the highest efficiency, and realize the fan high-efficiency operation mode. At this time, the flow field simulation diagram in the air outlet channel is as follows Figure 4 As shown, the flow field simulation diagram in the air outlet channel in the related art without the adjustment device is as follows Figure 3 As shown. Figure 5 In the figure, the horizontal axis is the fan speed, the vertical axis is the air volume flowing out of the air outlet channel, straight line 2 is the speed-air volume relationship diagram of the related technology without an adjustment device, and straight line 1 is the speed-air volume relationship diagram of the fan in the high-efficiency operation mode in this application. It can be seen that under the same speed, the air volume in this application is greater than the air volume in the related technology. The air volume, power and noise data of the fan in the high-efficiency operation mode in the related technology and this application at different fan speeds are shown in Tables 1 and 2 below, respectively, where the speed in Tables 1 and 2 refers to the fan speed, the air volume is the air volume flowing through the air outlet channel, the unit of power is the same and the test position is the same, the unit of noise is the same and the test position is the same, the difference is that no adjustment device is set in Table 1, while an adjustment device is set in Table 2, and the fan is in the high-efficiency operation mode.

[0079] Table 1

[0080] Speed ​​(r / min) Air volume (m3 / h) power noise 993 713.7 35.36 41.38 922 657.2 28.46 39.08 861 607.8 23.3 37.18

[0081] Table 2

[0082] Speed ​​(r / min) Air volume (m3 / h) power noise 993 753.2 35.36 41 922 697.5 28.46 38.76 861 648 23.3 36.79

[0083] It can be seen that at the same fan speed, the air volume in the related art is smaller than that in the present application, and the noise is greater than that in the present application.

[0084] Example six, when the outer frames 202 of the first adjustment device 203, the second adjustment device 204 and the third adjustment device 205 are all in the first gear extended position, the fan operates normally, the air conditioner is in silent operation mode, and the air outlet channel 101 is compressed as a whole, resulting in a decrease in the air outlet speed of the air outlet channel 101, achieving the purpose of noise reduction and silent operation, and realizing silent operation mode.

[0085] Example seven, when the outer frames 202 of the first adjustment device 203, the second adjustment device 204 and the third adjustment device 205 are all in the second gear extended position, the fan operates normally. At this time, the air outlet channel 101 is basically blocked, and the fan operates to discharge air to realize internal circulation in the volute 10, which can effectively clean the dust accumulated inside the air duct, achieve the purpose of self-cleaning, and realize the self-cleaning movement mode.

[0086] The user can adjust the position of the outer frame 202 manually, or it can be adjusted automatically.

[0087] Optionally, the air conditioner further includes a detection device for detecting parameters of the air conditioner and / or environmental parameters. The controller is also connected to the detection device for controlling the operation of the adjustment device according to the detection results of the detection device.

[0088] The air conditioner parameters include at least one of the pressure at the air duct outlet and the concentration of particulate matter within the air duct. The environmental parameters include at least one of the indoor temperature, humidity, and the concentration of particulate matter in the indoor or outdoor air. Controlling the operation of the regulating device based on the detection results of the detection device can enable the regulating device to operate better in different environments and under different requirements, thereby achieving automated regulation of the air conditioner and improving the intelligence of the air conditioner.

[0089] For example, the detection device is a sensor, which senses the air pressure at the air duct outlet or the air outlet channel 101. The controller controls the driving member to automatically adjust the deformation of the elastic member 201 in the adjustment device, so that the outer frame 202 is in a sub-extended position or a retracted position at different gears, so as to achieve the purpose of keeping the air outlet wind speed and air volume at the air duct outlet the same under different resistance conditions, realize the constant air volume operation mode of the air conditioner, and realize constant temperature cooling or heating.

[0090] For example, the sensor senses the concentration of particulate matter inside the air duct. When the concentration of particulate matter reaches a certain concentration, the self-cleaning mode is automatically turned on to self-clean the air duct.

[0091] In summary, by adjusting the deformation of the elastic member 201 in the adjusting device at different positions, the volume of the outer frame 202 is changed, thereby achieving the purpose of controlling the air outlet shape and air outlet area of ​​the air outlet channel 101.
