[0030] In order to solve the problem in the prior art that an air-conditioning device causes high noise due to eccentric vortex during operation, the present application provides a volute tongue structure, an air-conditioning device and a volute tongue structure control method.

[0031] like Figures 1 to 5 As shown, the volute tongue structure includes a volute tongue body 10, a rib assembly and a driving assembly. The rib assembly includes a plurality of rib teeth 20 arranged at intervals along a preset direction, and each rib tooth 20 is movably arranged on the volute tongue body 10. The driving assembly includes a driving device 30 and a transmission mechanism 40, at least some of the rib teeth 20 are connected through the transmission mechanism 40, and the driving device 30 is drivingly connected to at least one rib tooth 20 to drive the rib tooth 20 to drive the remaining rib teeth 20 to move relative to the volute tongue body 10 through the transmission mechanism 40.

[0032] By applying the technical solution of this embodiment, the rib teeth 20 and the snail tongue body 10 are split structures and are movably arranged relative to the snail tongue body. The rib teeth 20 are driven to move by the driving device 30 and the transmission mechanism 40 to adjust the angle of the rib teeth 20 relative to the snail tongue body 10, thereby improving the noise problem caused by eccentric eddy currents to a certain extent, thereby solving the problem of high noise caused by eccentric eddy currents during operation of the air-conditioning device in the prior art, and improving the user experience.

[0033] In this embodiment, each rib tooth 20 is rotatably disposed on the volute tongue body 10 via a pin shaft 110 .

[0034] Optionally, the transmission mechanism 40 includes a plurality of first connecting parts 41, and the plurality of first connecting parts 41 are arranged one by one corresponding to the plurality of rib teeth 20, and each rib tooth 20 is rotatably connected to the first connecting part 41 corresponding to the rib tooth 20, and each rib tooth 20 is rotatably connected to the volute tongue body 10, so that a four-bar linkage is formed between two adjacent rib teeth 20, the volute tongue body 10, and the transmission mechanism 40. In this way, one of the two adjacent rib teeth 20 is an active member and the other is a driven member, and the driving device 30 drives the active member to rotate relative to the volute tongue body 10, so as to drive the driven member to rotate synchronously through the transmission mechanism 40, thereby realizing the rotation of all rib teeth 20, which, on the one hand, makes the movement of the rib assembly more stable and reduces noise and vibration; on the other hand, reduces the number of driving devices 30, and reduces the control difficulty and processing cost of the volute tongue structure.

[0035] In this embodiment, the above-mentioned arrangement of the first connecting portion 41 increases the contact area between the transmission mechanism 40 and each rib tooth 20 , thereby improving the connection stability between the two.

[0036] like Figure 3 As shown, the driving device 30 is a motor, and the volute tongue structure also includes a noise detection device 50 and a control module. The noise detection device 50 is used to detect the noise decibels in the environment where the volute tongue body 10 is located. The control module is electrically connected to the motor and the noise detection device 50, and the control module controls the operating parameters of the motor according to the detection value of the noise detection device 50. Among them, the operating parameters include at least one of the motor speed, the motor rotation angle, and the start-stop state. In this way, the rotation angle of the rib teeth 20 is adjusted according to the noise detection device 50, thereby minimizing the noise generated by the eccentric eddy current during the operation of the air-conditioning device, thereby improving the user experience. At the same time, the above-mentioned arrangement makes the structure of the driving device 30 simpler, easier to process and realize, and reduces the processing cost and difficulty of the volute tongue structure.

[0037] Optionally, the noise detection device 50 is a noise sensor.

[0038] In this embodiment, the noise value of the air conditioning device is detected in real time by a noise sensor, and the swing angle of each rib tooth 20 is adjusted until the noise value reaches the best (ie, the lowest value) at this angle.

[0039] Optionally, the volute tongue body 10 has a plurality of mounting recesses 11, and the plurality of mounting recesses 11 are arranged one-to-one with the plurality of rib teeth 20, and each rib tooth 20 is rotatably arranged in the mounting recess 11 corresponding thereto. In this way, during the rotation of the rib teeth 20, the above arrangement of the mounting recesses 11 prevents the rib teeth 20 from interfering with other components in the air-conditioning device and affecting the normal operation of the air-conditioning device, thereby improving the operational reliability of the air-conditioning device.

[0040] In this embodiment, the surface of each rib tooth 20 facing away from the volute tongue body 10 is arranged flush with the surface of the volute tongue body 10 facing the cross-flow blower 60 .

[0041] like Figure 4 As shown, each rib tooth 20 includes a rib body 21 and a second connection portion 22. The second connection portion 22 is arranged on the side of the rib body 21, and the second connection portion 22 is engaged with the first connection portion 41. In this way, the above arrangement of the second connection portion 22 increases the contact area between the rib tooth 20 and the transmission mechanism 40, thereby improving the connection stability between the two; on the other hand, the position arrangement of the second connection portion 22 is more reasonable, avoiding motion interference between it and other components in the air conditioning device and affecting the normal operation of the air conditioning device.

[0042] Specifically, the second connection portion 22 is disposed on one side of the rib body 21. When the rib teeth are in the initial state, the other side of the rib body 21 and the side of the tongue body 10 are disposed parallel to each other.

[0043] like Figure 5 As shown, the transmission mechanism 40 further includes a rod body 42 and a plurality of extension arms 43. The plurality of extension arms 43 are arranged one-to-one with the plurality of first connection parts 41, one end of each extension arm 43 is connected to the rod body 42, and the other end of each extension arm 43 is connected to the corresponding first connection part 41. In this way, the above arrangement of the extension arm 43 ensures that it can extend between two adjacent rib teeth 20 to connect with the second connection part 22, thereby improving the connection stability between the transmission mechanism 40 and the rib teeth 20.

[0044] Specifically, each extension arm 43 includes a first rod segment, a second rod segment and a third rod segment that are bent sequentially, the first rod segment and the third rod segment are arranged opposite to each other, the first rod segment and the third rod segment are located on the same side of the second rod segment, the first rod segment is connected to the rod body 42, and the third rod segment is connected to the first connecting portion 41.

[0045] like Figure 4As shown, the second connection part 22 includes a first shaft section 221, and the first connection part 41 is an annular structure and has a mounting notch 411, and the annular structure is sleeved outside the first shaft section 221 through the mounting notch 411. In this way, the above arrangement facilitates the disassembly and assembly of the first connection part 41 and the second connection part 22, which can be done through the mounting notch 411, thereby reducing the labor intensity of the staff; on the other hand, the structure of the first connection part 41 is simpler, and it is easy to process and realize, thereby reducing the processing cost and difficulty of the transmission mechanism 40.

[0046] like Figure 4 As shown, the second connecting portion 22 includes a second shaft segment 222, a first shaft segment 221 and a third shaft segment 223 connected in sequence, the second shaft segment 222 and the third shaft segment 223 are arranged opposite to each other, the second shaft segment 222 and the first shaft segment 221 are arranged at a first angle, and the first shaft segment 221 and the third shaft segment 223 are arranged at a second angle. Optionally, the first angle is 90°. Optionally, the second angle is 90°. In this way, the first connecting portion 41 is sleeved on the first shaft segment 221 through the installation notch 411 and is limitedly matched with the first shaft segment 221, so that the transmission mechanism 40 and the rib tooth 20 can be disassembled and assembled more easily and conveniently, and the difficulty of disassembly and assembly of the two is reduced. At the same time, the above-mentioned arrangement makes the structure of the second connecting portion 22 simpler, easier to process and realize, and reduces the processing cost and difficulty of the rib tooth 20.

[0047] In this embodiment, the rib assembly is located on a side of the volute tongue body 10 close to the crossflow fan 60. In this way, the above arrangement can further reduce the noise generated by the eccentric vortex and improve the user experience.

[0048] like Figure 1 and Figure 2 As shown, the present application also provides an air conditioning device, including a casing 70 and an air conditioning body, wherein the casing 70 has an air inlet and an air outlet that are interconnected. The air conditioning body is arranged in the casing 70, and the air conditioning body includes a volute tongue structure and a crossflow fan 60. Among them, the volute tongue structure is the above-mentioned volute tongue structure.

[0049] like Figure 1 and Figure 2 As shown, the air conditioning device further includes a filter 80, an air guide plate 90 and an evaporator 100. The filter 80 is arranged at the air inlet, and the air guide plate 90 is arranged at the air outlet to control the opening and closing state of the air outlet and the air outlet angle. The evaporator 100 is arranged outside the crossflow fan 60.

[0050] like Figure 6 As shown, the present application also provides a method for controlling a volute tongue structure, which is applicable to the above-mentioned volute tongue structure. The method for controlling a volute tongue structure includes:

[0051] Step S1: obtaining the position of the rib teeth of the volute tongue structure to determine whether the rib teeth are in an initial state;

[0052] Step S2: If the rib teeth are in the initial state, the wind speed mode of the air-conditioning device is obtained to control the rotation angle of the rib teeth according to the wind speed mode; wherein the wind speed mode includes silent speed, low wind speed, medium-low wind speed, medium wind speed, medium-high wind speed, high wind speed and super strong speed.

[0053] Specifically, during the operation of the air-conditioning device, the rotation angle of the rib teeth is controlled according to the windshield mode, thereby improving the noise problem caused by the eccentric vortex to a certain extent, thereby solving the problem of high noise caused by the eccentric vortex during the operation of the air-conditioning device in the prior art, and improving the user experience.

[0054] In this embodiment, the method for judging whether the rib tooth is in the initial state includes: judging whether the side edge of the rib tooth is parallel to the side edge of the volute tongue body.

[0055] In this embodiment, the method for controlling the rotation angle of the rib teeth according to the windshield mode includes:

[0056] The rotation angle of the rib teeth is controlled according to the windshield rotation angle correspondence table, and the method for obtaining the windshield rotation angle correspondence table includes:

[0057] When the air-conditioning device is in the silent gear, low wind gear, medium-low wind gear, medium wind gear, medium-high wind gear, high wind gear, or extra-strong gear, adjust the rotation angle of the rib teeth to record the rotation angle of the rib teeth when the detection value of the noise detection device is minimum, thereby forming a windshield rotation angle correspondence table between the windshield mode and the rotation angle of the rib teeth.

[0058] Specifically, when the user turns on the power and starts the air conditioning device, the air conditioning device first performs a self-test to detect the initial state of the volute structure at this time, that is, the swing angle of the rib teeth. Since the mechanism composed of any two rib teeth, the transmission mechanism, and the volute body is a parallelogram mechanism, and the swing angle of the rib teeth is equal to the rotation angle of the motor, the detected rib swing angle is the rotation angle of the motor. Among them, when the rib teeth are in the initial state, the swing angle of the rib teeth is first defined as 0°. If the swing angle of the rib teeth is not 0° during the power-on self-test, the motor is powered on and rotated a certain angle to drive the rib teeth to return to the 0° state. According to the working state set by the user, the air conditioning device starts to operate normally, and the noise detection device starts to work to detect the operating noise of the air conditioning device in the air duct. The control module obtains the mapping relationship between the operating noise and the rib tooth rotation angle according to the detection value of the noise detection device and the different wind speed modes of the air conditioning device (i.e., 7 wind speed modes in total, namely, silent gear / low wind speed / medium-low wind speed / medium wind speed / medium-high wind speed / high wind speed / super strong gear), outputs the rotation angle of the rib tooth corresponding to the lowest noise value in this state, and sends the instruction to the motor. The motor drives the rib tooth to rotate to the target angle and then self-locks. The noise detection device detects the noise value in the air duct again. If the lowest noise value is reached, the motor loses power and stops and self-locks; if the lowest noise value is not reached, the above steps are repeated. When the user sets the shutdown, the air conditioner self-detects whether the swing angle of the rib tooth is the initial value of 0°. If the result is yes, it automatically enters the shutdown procedure to complete the shutdown; if the result is no, the motor rotates to the 0° position and then enters the shutdown procedure to complete the shutdown.

[0059] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0060] The snail tongue structure includes a snail tongue body, a rib assembly and a driving assembly. The rib assembly includes a plurality of rib teeth arranged at intervals along a preset direction, and each rib tooth is movably arranged on the snail tongue body.

In this way, the rib teeth and the snail tongue body are a split structure and are movably arranged relative to the snail tongue body. The rib teeth are driven to move by the driving device and the transmission mechanism to adjust the angle of the rib teeth relative to the snail tongue body, thereby improving the noise problem caused by the eccentric vortex to a certain extent, thereby solving the problem of high noise caused by the eccentric vortex during the operation of the air-conditioning device in the prior art, and improving the user experience.
