Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning equipment, and in particular to a control method of an air conditioner, a volute control system, an air conditioner and related devices. Background Art

[0002] When the air conditioner is in cooling or dehumidification mode, due to the low temperature of the condenser, when the air with high humidity contacts the condenser, condensation will be generated on the surface of the condenser. When there is a lot of condensation, it will drip onto the fan below the condenser. Under the centrifugal force generated by the rotation of the fan, the condensation will be thrown out of the air outlet, reducing the user experience. In order to solve the above problems, existing air conditioners usually arrange a volute tongue between the fan and the condenser to prevent the condensation from dripping onto the fan.

[0003] However, since there is an air inlet channel between the fan and the condenser, the layout of the volute tongue will reduce the air intake, which will lead to a decrease in the air output of the air conditioner, thereby reducing the cooling or dehumidification effect. Therefore, how to avoid the splashing of condensed water while preventing the cooling or dehumidification effect of the air conditioner from decreasing has become an urgent problem to be solved. Summary of the invention

[0004] In view of the above problems, the present application provides a control method of an air conditioner, a volute control system, an air conditioner and related devices to achieve the purpose of avoiding the splashing of condensed water while preventing the reduction of the air conditioning refrigeration or dehumidification effect. The specific scheme is as follows:

[0005] In a first aspect, the present application provides a control method for an air conditioner, which is applied to an air conditioner controller. The control method for the air conditioner includes:

[0006] When it is detected that the current operation mode is the cooling mode or the dehumidification mode, determining whether the indoor air humidity is greater than a preset humidity threshold, and determining whether the current coil temperature of the condenser is not greater than a preset temperature threshold;

[0007] When the indoor air humidity is greater than the preset humidity threshold and the current coil temperature of the condenser is not greater than the preset temperature threshold, the volute tongue body is controlled to move from the first position to the second position, and the water receiving area of ​​the volute tongue body at the second position is greater than the water receiving area at the first position;

[0008] When the indoor air humidity is not greater than the preset humidity threshold, or the current coil temperature of the condenser is greater than the preset temperature threshold, the volute tongue body is controlled to move from the third position to the fourth position, the water receiving area of ​​the volute tongue body at the third position is greater than the water receiving area at the fourth position, and the second position is the same as or different from the third position;

[0009] After the volute tongue body moves to the second position, a first regulating operation is performed on the speed of the fan based on a first air inlet speed of the volute tongue body when it is at the first position and a second air inlet speed of the volute tongue body when it is at the second position, so that the speed after the first regulating operation is greater than the speed before the first regulating operation;

[0010] After the volute tongue body moves to the fourth position, a second control operation is performed on the fan speed based on the third air inlet speed of the volute tongue body when it is in the third position and the fourth air inlet speed when it is in the fourth position, so that the speed after the second control operation is not greater than the speed before the second control operation.

[0011] In a possible implementation, the controlling the volute tongue body to move from the first position to the second position includes:

[0012] Obtaining a first position identifier when the volute tongue body is in the first position, and a second position identifier corresponding to the preset temperature range where the current coil temperature is located;

[0013] Determining a movement vector of the volute tongue body based on the first position identifier and the second position identifier;

[0014] The volute tongue body is controlled to move from the first position to the second position based on the movement vector.

[0015] In a possible implementation, the first regulating operation on the speed of the fan based on the first inlet wind speed when the volute tongue body is in the first position and the second inlet wind speed when the volute tongue body is in the second position includes:

[0016] Obtain a first wind speed difference between the first air inlet wind speed and the second air inlet wind speed, and obtain a first speed variable value having a mapping relationship with the first wind speed difference by querying a preset mapping relationship table, and update the speed of the fan to the sum of the current speed and the first speed variable value, where the first speed variable value is a positive number.

[0017] In a possible implementation, the second regulating operation on the speed of the fan based on the third air inlet speed of the volute tongue body when the volute tongue body is in the third position and the fourth air inlet speed of the volute tongue body when the volute tongue body is in the fourth position includes:

[0018] A second wind speed difference between the third air inlet wind speed and the fourth air inlet wind speed is obtained, and a second speed variable value having a mapping relationship with the second wind speed difference is obtained by querying a preset mapping relationship table, and the speed of the fan is updated to the sum of the current speed and the second speed variable value, where the second speed variable value is a non-positive number.

[0019] In a possible implementation, after completing the first regulation operation or completing the second regulation operation, the method further includes:

[0020] Start timing; if the timing duration is not less than the preset timing duration threshold, stop timing, collect the indoor air humidity at the timing stop time, and update the current coil temperature of the condenser to the coil temperature at the timing stop time;

[0021] The operating steps of determining whether the indoor air humidity is greater than a preset humidity threshold and determining whether the current coil temperature of the condenser is not greater than a preset temperature threshold are performed when the current operating mode is detected to be a cooling mode or a dehumidification mode.

[0022] A second aspect of the present application provides an air conditioning controller, comprising at least one processor and a memory connected to the processor, wherein:

[0023] The memory is used to store computer programs;

[0024] The processor is used to execute the computer program so that the electronic device can implement the control method of the air conditioner provided in the first aspect of the present application and any possible implementation thereof.

[0025] The third aspect of the present application provides a volute tongue control system, the volute tongue control system comprising: an air conditioning controller provided in the second aspect of the present application, a drive motor, a transmission mechanism and a volute tongue body,

[0026] The volute tongue body is equipped with a water receiving tray, and the volute tongue body is arranged at one end of the transmission mechanism. The air-conditioning controller sends a control instruction generated based on the indoor air humidity and the current coil temperature of the condenser to the drive motor, so that the drive motor drives the volute tongue body to move in the air inlet duct of the air conditioner through the transmission mechanism.

[0027] In a possible implementation, the transmission mechanism includes:

[0028] Arc support and transmission gear,

[0029] The outer arc side of the arc-shaped support body is provided with a tooth groove, the tooth groove is meshed with the transmission gear, and the transmission gear is connected to the output shaft of the drive motor.

[0030] A fourth aspect of the present application provides an air conditioner, comprising the volute control system provided in the third aspect of the present application and its possible implementation.

[0031] The fifth aspect of the present application provides a computer storage medium, which carries one or more computer programs. When the one or more computer programs are executed by an air-conditioning controller, the air-conditioning controller can implement the control method of the air conditioner provided in the first aspect of the present application and any possible implementation thereof.

[0032] By means of the above technical scheme, the control method, volute control system, air conditioner and related devices of the air conditioner provided by the present application are configured to control the volute body to move from the first position with a small water receiving area to the second position with a large water receiving area based on the current coil temperature when the indoor air humidity is detected to be greater than the preset humidity threshold and the current coil temperature of the condenser is not greater than the preset temperature threshold, thereby avoiding the splashing of condensed water falling on the fan. Subsequently, after the volute body moves to the second position, the first air inlet speed of the volute body at the first position and the second air inlet speed at the second position are configured to perform a first control operation on the speed of the fan, so that the speed after the first control operation is not less than the speed before the first control operation, thereby avoiding the risk of reducing the air intake volume due to the volute body blocking the air inlet channel, thereby reducing the cooling or dehumidification effect of the air conditioner. Moreover, after the volute body moves to the fourth position, the second control operation is performed on the speed of the fan based on the third air inlet speed of the volute body at the third position and the fourth air inlet speed at the fourth position, so that the speed after the second control operation is not greater than the speed before the second control operation, thereby avoiding the risk of increased energy consumption caused by the fan maintaining a high speed for a long time. It can be seen that the present application avoids the drop in air conditioning refrigeration or dehumidification effect while avoiding splashing of condensed water.

[0040] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0041] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0042] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0043] The first aspect of the present application provides a control method for an air conditioner, which is applied to an air conditioner controller, such as Figure 1 As shown, the control method of the air conditioner includes:

[0044] S101. When it is detected that the current operation mode is a cooling mode or a dehumidification mode, it is determined whether the indoor air humidity is greater than a preset humidity threshold, and it is determined whether the current coil temperature of the condenser is not greater than a preset temperature threshold.

[0045] It should be noted that, in actual application scenarios, the above detection of whether the current operating mode is cooling mode or dehumidification mode can be achieved by the air conditioner controller identifying the control signal in the control signal receiving list whose import time is closest to the current time. Since the condenser temperature is high when the air conditioner is in heating mode and no condensed water is generated, there is no need to execute the control method of the air conditioner provided in this application when the current operating mode is heating mode.

[0046] It should be noted that, in actual application scenarios, the indoor air humidity can be collected by a humidity sensor deployed in the air conditioner. The current coil temperature of the condenser can be collected by a coil temperature sensor in the condenser. The preset humidity threshold can be the minimum indoor air humidity value that characterizes the generation of condensed water based on the statistics of the measured parameters. The preset temperature threshold can be the maximum coil temperature value that characterizes the generation of condensed water based on the statistics of the measured parameters.

[0047] S102. When the indoor air humidity is greater than a preset humidity threshold and the current coil temperature of the condenser is not greater than a preset temperature threshold, control the volute tongue body to move from a first position to a second position, and the water receiving area of ​​the volute tongue body at the second position is greater than the water receiving area at the first position.

[0048] It should be noted that in actual application scenarios, the schematic diagram of the installation position of the snail tongue body can be as follows: Figure 2 The positional relationship between the condenser 21, the inner wall 22 of the air conditioner and the fan 23 is shown in FIG. Figure 2 As shown, the positional relationship of the volute tongue body relative to the condenser 21 when the volute tongue body is in the first position 24 and the second position 25 is as shown in FIG. Figure 2 As shown. When a small amount of condensed water on the surface of the condenser 21 flows to the bottom of the condenser due to gravity, the volute tongue body located at the first position 24 will receive the condensed water at the bottom of the condenser 21 to prevent the condensed water from falling on the fan 23 and causing splashing. However, when the indoor air humidity is greater than the preset humidity threshold and the current coil temperature of the condenser is not greater than the preset temperature threshold, a large amount of condensed water will be generated on the surface of the condenser 21. At this time, when the condensed water flows along the surface of the condenser 21, large mass condensed water droplets will be generated due to the convergence of water droplets, which will cause the condensed water to drip onto the fan 23 in the process of flowing to the bottom of the condenser 21, thereby causing the condensed water to splash. However, the present application is configured to control the volute tongue body to move from the first position 24 to the second position 25 when the indoor air humidity is greater than the preset humidity threshold and the current coil temperature of the condenser is not greater than the preset temperature threshold. Since the water receiving area of ​​the volute tongue body at the second position 25 is greater than the water receiving area at the first position 24, the volute tongue body can receive the condensed water droplets dripping in the process of flowing to the bottom of the condenser, thereby avoiding the risk of condensed water splashing.

[0049] It should be noted that, in actual application scenarios, the first position is the position of the snail tongue body at the time of indoor air humidity or current coil temperature collection.

[0050] It should be noted that, in actual application scenarios, in order to prevent condensed water from flowing into the air outlet along the volute tongue body, the volute tongue body may be configured with a water receiving tray. The present application does not make too many restrictions or redundant descriptions on the deployment position and shape of the water receiving tray.

[0051] S103. When the indoor air humidity is not greater than a preset humidity threshold, or the current coil temperature of the condenser is greater than a preset temperature threshold, the volute tongue body is controlled to move from the third position to the fourth position, the water receiving area of ​​the volute tongue body at the third position is greater than the water receiving area at the fourth position, and the second position is the same as or different from the third position.

[0052] It should be noted that in actual application scenarios, the above Figure 2 It can be seen from the schematic diagram of the installation position of the volute tongue body that when the volute tongue body is in the second position, although the water receiving area is increased, the volute tongue body also occupies the air inlet channel, resulting in a decrease in the air intake volume, thereby causing the cooling or dehumidification effect of the air conditioner to decrease. Therefore, the present application controls the volute tongue body to move from the third position to the fourth position by configuring the indoor air humidity to be not greater than the preset humidity threshold, or the current coil temperature of the condenser is greater than the preset temperature threshold, thereby avoiding the risk of the volute tongue body occupying the air inlet channel for a long time, resulting in a decrease in the air intake volume, and then causing the cooling or dehumidification effect of the air conditioner to decrease. At the same time, because when the indoor air humidity is not greater than the preset humidity threshold, or the current coil temperature of the condenser is greater than the preset temperature threshold, the amount of condensed water on the condenser surface is small and will not drip during the flow on the condenser surface. Therefore, by configuring the volute tongue body to have a water receiving area in the third position greater than the water receiving area in the fourth position, the risk of condensed water dripping and splashing at the bottom of the condenser is avoided.

[0053] In one possible implementation, if the indoor air humidity is not greater than a preset humidity threshold, or the current coil temperature of the condenser is greater than a preset temperature threshold, and the condenser is located at a position with the smallest water receiving area, the volute tongue body can be maintained at its current position without moving.

[0054] It should be noted that, in actual application scenarios, the third position is the position of the snail tongue body at the time of indoor air humidity or current coil temperature collection.

[0055] S104. After the volute tongue body moves to the second position, a first regulating operation is performed on the fan speed based on the first air inlet speed of the volute tongue body when it is in the first position and the second air inlet speed of the volute tongue body when it is in the second position, so that the speed after the first regulating operation is greater than the speed before the first regulating operation.

[0056] It should be noted that in actual application scenarios, when the volute tongue body moves to the second position, the volute tongue body will block the air inlet channel, causing the air intake volume to decrease. In order to avoid splashing of condensation water while avoiding a decrease in the cooling or dehumidification effect of the air conditioner, the present application performs a first control operation on the fan speed based on the first air inlet speed when the volute tongue body is in the first position and the second air inlet speed when the volute tongue body is in the second position, so that the speed after the first control operation is greater than the speed before the first control operation, thereby compensating for the air intake volume blocked by the volute tongue body by increasing the fan speed.

[0057] S105. After the volute tongue body moves to the fourth position, a second control operation is performed on the fan speed based on the third air inlet speed when the volute tongue body is at the third position and the fourth air inlet speed when the volute tongue body is at the fourth position, so that the speed after the second control operation is not greater than the speed before the second control operation.

[0058] It should be noted that, in actual application scenarios, since the amount of airflow blocked by the volute tongue body when it is in the third position is greater than the amount of airflow blocked when it is in the fourth position, and it can be seen from step S104 that when the volute tongue body is in the third position, in order to compensate for the blocked airflow, the fan will increase the speed, which will inevitably lead to an increase or decrease in air conditioning energy consumption. Therefore, the present application performs a second control operation on the speed of the fan based on the third airflow speed when the volute tongue body is in the third position and the fourth airflow speed when the volute tongue body is in the fourth position after the volute tongue body moves to the fourth position, so that the speed after the second control operation is not greater than the speed before the second control operation, thereby avoiding long-term high-speed operation of the fan and reducing air conditioning energy consumption.

[0059] The present application is configured to control the volute tongue body to move from the first position with a small water receiving area to the second position with a large water receiving area based on the current coil temperature when the indoor air humidity is detected to be greater than the preset humidity threshold and the current coil temperature of the condenser is not greater than the preset temperature threshold, thereby avoiding condensed water from falling on the fan and splashing. Subsequently, after the volute tongue body moves to the second position, a first control operation is performed on the speed of the fan based on the first air inlet speed of the volute tongue body at the first position and the second air inlet speed at the second position, so that the speed after the first control operation is not less than the speed before the first control operation, thereby avoiding the risk of reducing the air intake volume due to the volute tongue body blocking the air inlet channel, thereby reducing the cooling or dehumidification effect of the air conditioner. In addition, after the volute tongue body moves to the fourth position, a second control operation is performed on the speed of the fan based on the third air inlet speed of the volute tongue body at the third position and the fourth air inlet speed at the fourth position, so that the speed after the second control operation is not greater than the speed before the second control operation, thereby avoiding the risk of increased energy consumption caused by the fan maintaining a high speed for a long time. It can be seen that the present application avoids the drop in air conditioning refrigeration or dehumidification effect while avoiding splashing of condensed water.

[0060] In a possible implementation, controlling the volute tongue body to move from the first position to the second position includes:

[0061] Obtaining a first position identifier when the volute tongue body is in the first position, and a second position identifier corresponding to a preset temperature range where the current coil temperature is located;

[0062] Determining a movement vector of the volute tongue body based on the first position identifier and the second position identifier;

[0063] The volute tongue body is controlled to move from a first position to a second position based on the movement vector.

[0064] It should be noted that in actual application scenarios, the first position mark and the second position mark are used to indicate the position where the condensed water drips on the condenser surface and the volute tongue body can receive the dripping condensed water. The researchers of this application have found through a large number of experiments that the dripping position of condensed water is greatly affected by the temperature of the condenser coil. Figure 3 The figure shows a schematic diagram of the condensed water dripping position. When the temperature of the condenser 31 coil is low, the amount of condensed water on the surface of the condenser 31 increases, and the condensed water will drip before it flows to the middle position 35 of the condenser. When the temperature of the condenser 31 coil is high, the amount of condensed water on the surface of the condenser 31 decreases. Due to the small amount of convergence, the condensed water will not drip until it finally converges at the bottom position 34 of the condenser. Assuming that the volute tongue body is currently located at the first position 33, the condensed water drips at the bottom position 34 of the condenser. Since the water receiving area of ​​the volute tongue body covers the condensed water dripping position, the condensed water will not fall on the fan 32 to avoid splashing. When the position represented by the second position mark corresponding to the preset temperature interval where the current coil temperature of the condenser is located is the middle position 35 of the condenser, if the volute tongue body is still located at the first position 33, the condensed water will drip on the fan 32 to cause splashing. Therefore, the present application moves the volute tongue body from the first position 33 to the second position 36 corresponding to the second position mark based on the second position mark, so that the water receiving area of ​​the volute tongue body covers the middle position 35 of the condenser and the bottom position 34 of the condenser, thereby avoiding the risk of condensed water splashing. It can be seen that the present application configures the correspondence between the preset temperature range and the position mark, and determines the second position mark to which the volute tongue body is to be moved based on the preset temperature range where the current coil temperature is located, thereby improving the efficiency of the volute tongue body in receiving condensed water and avoiding the risk of condensed water splashing.

[0065] It should be noted that, in actual application scenarios, the above movement vector is a vector including a movement distance and a movement direction. By determining the above movement vector, the driving mechanism of the volute tongue body can move the volute tongue body from the first position to the second position.

[0066] In a possible implementation, the method of controlling the volute tongue body to move from the third position to the fourth position may be:

[0067] Obtaining a third position identifier when the volute tongue body is in the third position, and a fourth position identifier corresponding to the preset temperature range where the current coil temperature is located;

[0068] Determine a movement vector of the volute tongue body based on the third position marker and the fourth position marker;

[0069] The volute tongue body is controlled to move from the third position to the fourth position based on the movement vector.

[0070] In a possible implementation, performing a first regulating operation on the speed of the fan based on a first inlet wind speed when the volute tongue body is in the first position and a second inlet wind speed when the volute tongue body is in the second position includes:

[0071] Obtain a first wind speed difference between the first air inlet wind speed and the second air inlet wind speed, and obtain a first speed variable value having a mapping relationship with the first wind speed difference by querying a preset mapping relationship table, and update the fan speed to the sum of the current speed and the first speed variable value, where the first speed variable value is a positive number.

[0072] It should be noted that in actual application scenarios, since the wind speed difference and the speed variable value are two types of data with different dimensions, and since the air intake channel aerodynamic characteristics of different models of air conditioners are different, the conversion between the wind speed difference and the speed variable value is relatively complicated. Therefore, the present application configures the above-mentioned preset mapping relationship table to store the wind speed difference and the speed variable value with a mapping relationship therewith, thereby improving the execution efficiency of controlling the fan speed.

[0073] It should be noted that, in actual application scenarios, the process of constructing the above-mentioned preset mapping relationship table can be: performing an aerodynamic characteristic analysis on the air inlet channel of the target model of the air conditioner, and in the analysis process, using the wind speed sensor configured on the volute tongue body to collect the difference in wind speed values ​​in the air inlet channel when the volute tongue body changes position once. Subsequently, after removing the volute tongue body, collect the air intake volume of the fan at different speeds. Thus, the mapping relationship between the wind speed difference and the fan speed is determined based on the air intake volume, and the above-mentioned preset mapping relationship table is constructed.

[0074] It should be noted that in actual application scenarios, in order to improve control accuracy, multiple preset temperature intervals and their corresponding position identifiers can be configured. When the differences in the preset temperature intervals are small, the slight fluctuation in the fan speed has a low impact on the cooling or dehumidification effect of the air conditioner. Therefore, in order to reduce energy consumption, after obtaining the first wind speed difference between the first wind speed and the second wind speed, steps A1 to A3 as shown below can also be performed to determine whether the fan speed needs to be regulated.

[0075] Step A1, determine whether the first wind speed difference is less than a preset fluctuation speed threshold. If yes, trigger step A2, if no, trigger step A3.

[0076] Step A2: maintaining the current speed of the fan.

[0077] Step A3, querying a preset mapping relationship table to obtain a first speed variable value having a mapping relationship with the first wind speed difference, and updating the speed of the fan to the sum of the current speed and the first speed variable value.

[0078] In a possible implementation, performing a second control operation on the speed of the fan based on the third air inlet speed when the volute tongue body is in the third position and the fourth air inlet speed when the volute tongue body is in the fourth position includes:

[0079] Obtain a second wind speed difference between the third air inlet wind speed and the fourth air inlet wind speed, and obtain a second speed variable value having a mapping relationship with the second wind speed difference by querying a preset mapping relationship table, and update the fan speed to the sum of the current speed and the second speed variable value, where the second speed variable value is a non-positive number.

[0080] It should be noted that in actual application scenarios, the present application updates the fan speed to the sum of the current speed and a non-positive second speed variable value through configuration, thereby avoiding the risk of increased energy consumption caused by the fan being at a high speed for a long time.

[0081] In a possible implementation, after the first regulation operation is completed, or after the second regulation operation is completed, the above Figure 1 The control method of the air conditioner shown also includes:

[0082] Start timing; if the timing duration is not less than the preset timing duration threshold, stop timing, collect the indoor air humidity at the timing stop time, and update the current coil temperature of the condenser to the coil temperature at the timing stop time;

[0083] The operating steps of determining whether the indoor air humidity is greater than a preset humidity threshold and determining whether the current coil temperature of the condenser is not greater than a preset temperature threshold are performed when detecting that the current operating mode is a cooling mode or a dehumidification mode.

[0084] It should be noted that in actual application scenarios, since the air conditioner will automatically adjust the indoor air parameters according to the indoor environmental parameters, the present application is configured to stop timing when the timing duration is not less than the preset timing duration threshold, collect the indoor air humidity at the timing stop time, and update the current coil temperature of the condenser to the coil temperature at the timing stop time; execute the operating steps of judging whether the indoor air humidity is greater than the preset humidity threshold and judging whether the current coil temperature of the condenser is not greater than the preset temperature threshold when it is detected that the current operating mode is cooling mode or dehumidification mode, thereby realizing automatic control without human intervention and improving user experience.

[0085] In order to facilitate the above Figure 1 The understanding of the control method of the air conditioner shown is explained here in combination with a possible implementation of the present application:

[0086] like Figure 4 FIG. 1 is a flow chart of a method for controlling an air conditioner, and the specific operation steps are as follows:

[0087] Step S401, the air conditioner is turned on, and step S402 is triggered.

[0088] Step S402, determining whether the current operation mode is the heating mode, if not, triggering step S403, and if so, triggering step S404.

[0089] Step S403, determining whether the indoor air humidity is greater than a preset humidity threshold. If not, step S405 is triggered, and if so, step S406 is triggered.

[0090] Step S404: no intervention.

[0091] Step S405, determining whether there is a target position whose water receiving area is smaller than the current position of the snail tongue body. If not, step S407 is triggered, and if so, step S408 is triggered.

[0092] Step S406, determining whether the current coil temperature of the condenser is not greater than a preset temperature threshold, if yes, triggering step S409, if no, triggering step S410.

[0093] Step S407, maintaining the tongue body at the current position, and triggering step S417.

[0094] Step S408, controlling the tongue body to move from the current position to the target position, and triggering step S419.
