Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an indoor air conditioner unit, an air conditioner, and a control method thereof. Background Technology

[0002] In the design of air conditioning indoor units, cross-flow fans are widely used due to their unique airflow transmission method. However, due to the suction characteristics of cross-flow fans, the air volume passing through some sections of the heat exchanger is relatively large, resulting in excessively fast airflow velocity. This uneven airflow distribution leads to reduced heat exchange efficiency in some sections, thus affecting the overall performance and energy efficiency of the air conditioner.

[0003] Traditional air conditioner indoor unit designs face significant challenges in controlling the uniformity of airflow across the heat exchanger tubes. Uneven airflow velocity can prevent some tube sections from receiving adequate cooling or heating, thus affecting the air conditioner's cooling or heating performance. This not only reduces the air conditioner's efficiency but also increases energy consumption, ultimately impacting its performance. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in related technologies. To this end, this invention proposes an indoor air conditioning unit, an air conditioner, and a control method thereof, which solves the problem of uneven airflow velocity in existing air conditioners, which prevents some pipe sections from being adequately cooled or heated, thereby affecting the cooling or heating effect of the air conditioner.

[0005] An indoor air conditioning unit according to a first aspect embodiment of the present invention includes:

[0006] The shell has an air duct, and the two ends of the air duct are respectively provided with an air inlet and an air outlet;

[0007] A cross-flow fan is installed in the air duct;

[0008] An indoor heat exchanger includes a first pipe section, a second pipe section, and a third pipe section connected in sequence, all of which are located in the air duct.

[0009] The splitter is movably disposed in the air duct, located between the air inlet and the first pipe section, and disposed opposite to the first pipe section;

[0010] The system comprises a first temperature sensor, a second temperature sensor, and a controller. The first temperature sensor is disposed in the first pipe section, and the second temperature sensor is disposed in the second pipe section and / or the third pipe section. The controller is electrically connected to the splitter, the first temperature sensor, and the second temperature sensor to control the splitter to adjust the airflow at the first pipe section by detecting the temperature.

[0011] According to one embodiment of the present invention, the diverter includes: a diverter plate, a driving roller, a driven roller, a belt, and a drive mechanism;

[0012] The belt is arranged along the extension direction of the air duct and is sleeved on the active roller and the driven roller; the splitter plate is connected to the belt, located between the air inlet and the first pipe section, and is arranged opposite to the first pipe section; the drive mechanism is electrically connected to the controller, and the drive end of the drive mechanism is connected to the active roller to drive the splitter plate to move, so as to adjust the air volume at the first pipe section.

[0013] According to one embodiment of the present invention, the diverter plate is movable between a first position and a second position;

[0014] When the flow divider moves to the first position, the flow divider moves to the air inlet;

[0015] When the diverter plate moves to the second position, it moves to the edge of the first pipe section to block the air blown from the air inlet toward the first pipe section.

[0016] An air conditioner provided according to a second aspect of the present invention includes: the above-described air conditioner indoor unit.

[0017] A control method for an indoor air conditioning unit according to a third aspect embodiment of the present invention includes:

[0018] Acquire the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor;

[0019] The splitter is adjusted based on the first difference between the first temperature and the second temperature to regulate the airflow at the first pipe section.

[0020] According to an embodiment of the present invention, the step of adjusting the splitter based on the first difference between the first temperature and the second temperature to adjust the airflow at the first pipe section includes:

[0021] Determine a first difference between the first temperature and the second temperature;

[0022] Based on the first difference and the preset value, adjust the moving position of the diverter plate;

[0023] When the first difference is greater than the preset value, the flow divider is controlled to move to the second position;

[0024] When the first difference is less than or equal to the preset value, the diverter plate is controlled to move to a preset position between the first position and the second position.

[0025] According to one embodiment of the present invention, the distance between the preset position and the air inlet is positively correlated with the absolute value of the first difference, H = A × |ΔT|;

[0026] Where H is the distance between the preset position and the air inlet, A is the adjustment coefficient, and ΔT is the first difference.

[0027] According to an embodiment of the present invention, after the step of adjusting the splitter based on the first difference between the first temperature and the second temperature to adjust the airflow at the first pipe section, the method further includes:

[0028] The third temperature detected by the first temperature sensor and the fourth temperature detected by the second temperature sensor are obtained.

[0029] Determine the second difference between the third temperature and the fourth temperature, and adjust the position of the flow divider based on the preset position.

[0030] According to an embodiment of the present invention, the step of determining a second difference between the third temperature and the fourth temperature, and adjusting the position of the manifold based on the preset position, includes:

[0031] Match the temperature range corresponding to the second difference; wherein each temperature range corresponds to an adjustment distance;

[0032] Based on the adjustment distance corresponding to the temperature range, the basic control diverter moves at the preset position.

[0033] According to one embodiment of the present invention, the adjustment distance is positively correlated with the absolute value of the second difference.

[0034] The air conditioner indoor unit provided by this invention precisely controls the movement position of the distributor by detecting the temperature of different pipes, thereby achieving precise adjustment of the airflow distribution in the duct. This makes the airflow in each pipe section of the heat exchanger more uniform, effectively solving the problem of low heat exchange efficiency in some pipe sections due to excessive airflow. The uniform airflow distribution not only improves heat exchange efficiency but also makes the cooling or heating effect more uniform, significantly improving the performance of the air conditioner.

[0051] An indoor air conditioning unit according to a first aspect embodiment of the present invention. For example... Figures 1 to 4As shown, the indoor unit of the air conditioner includes: a housing 10, a cross-flow fan 20, an indoor heat exchanger 30, a splitter 40, a first temperature sensor 50, a second temperature sensor 60, and a controller.

[0052] In this embodiment, the housing 10 is the main structure of the indoor unit of the air conditioner, forming an air duct for air circulation. An air inlet 110 and an air outlet 120 are respectively provided at both ends of the air duct. The air inlet 110 is used to draw in indoor air, and the air outlet 120 is used to discharge treated air, thereby achieving indoor air circulation.

[0053] The cross-flow fan 20 is installed in the air duct and is a key component that drives airflow. When the cross-flow fan 20 is running, it can draw in outdoor air from the air inlet 110, and after passing through the indoor heat exchanger 30, it can be discharged from the air outlet 120.

[0054] The indoor heat exchanger 30 includes a first pipe section 310, a second pipe section 320, and a third pipe section 330 connected in sequence. The first pipe section 310, the second pipe section 320, and the third pipe section 330 are all installed in the air duct and are used to exchange heat with the passing air, thereby realizing the function of cooling or heating.

[0055] The splitter 40 is one of the key components of this invention. It is movably installed in the air duct, located between the air inlet 110 and the first pipe section 310, and is positioned opposite to the first pipe section 310. By adjusting the position of the splitter 40, the airflow entering the first pipe section 310 can be controlled, thereby achieving precise control of the airflow distribution.

[0056] A first temperature sensor 50, a second temperature sensor 60, and a controller are used. The first temperature sensor 50 is located in the first pipe section 310 to detect the temperature at that location. The second temperature sensor 60 is located in the second pipe section 320 or the third pipe section 330 to detect the temperature of those sections. The controller is electrically connected to the splitter 40, the first temperature sensor 50, and the second temperature sensor 60. These temperature sensors provide the controller with accurate temperature data, allowing it to precisely adjust the position of the splitter 40 based on this data, thereby controlling the airflow at the first pipe section 310 by controlling the splitter 40 based on temperature detection.

[0057] In practical applications, the controller can determine the heat exchange efficiency of each pipe section of the indoor heat exchanger 30 based on the temperature difference detected by the first temperature sensor 50 and the second temperature sensor 60, and adjust the moving position of the distributor 40 accordingly.

[0058] For example, such as Figure 3As shown, during the cooling process of the air conditioner, when the temperature detected by the first temperature sensor 50 is much higher than the temperature detected by the second temperature sensor 60, it indicates that the heat exchange efficiency of the first pipe section 310 is low. At this time, the controller can control the flow divider 40 to move, block the air towards the first pipe section 310, reduce the amount of air blown towards the first pipe section 310, and lower its temperature.

[0059] The air conditioner indoor unit provided by this invention precisely controls the movement position of the distributor by detecting the temperature of different pipes, thereby achieving precise adjustment of the airflow distribution in the duct. This makes the airflow in each pipe section of the heat exchanger more uniform, effectively solving the problem of low heat exchange efficiency in some pipe sections due to excessive airflow. The uniform airflow distribution not only improves heat exchange efficiency but also makes the cooling or heating effect more uniform, significantly improving the performance of the air conditioner.

[0060] In one example, such as Figures 1 to 4 As shown, the splitter 40 includes: a splitter plate 410, a driving roller 430, a driven roller 440, a belt 450, and a drive mechanism 420. These components each perform different functions, but they work together to regulate the airflow.

[0061] A belt 450 is positioned along the extension direction of the air duct and is fitted onto the drive roller 430 and the driven roller 440. Thus, when the drive roller 430 rotates, the belt 450 moves accordingly, thereby driving the driven roller 440 to rotate as well. This design allows the belt 450 to function as a transmission mechanism, transmitting power from the drive mechanism 420 to the splitter plate 410.

[0062] The diverter plate 410 is connected to the belt 450 and is located between the air inlet 110 and the first duct section 310, and is positioned opposite to the first duct section 310. Therefore, when the belt 450 moves, the diverter plate 410 also moves accordingly. By adjusting the position of the diverter plate 410, the airflow entering the first duct section 310 can be changed. This design makes airflow adjustment flexible and convenient.

[0063] The drive mechanism 420 is electrically connected to the controller, and its drive end is connected to the drive roller 430. Thus, when the controller issues a command, the drive mechanism 420 can drive the drive roller 430 to rotate, which in turn drives the splitter plate 410 to move via the belt 450. This design allows for remote control of airflow adjustment via electrical signals, improving operational convenience.

[0064] During actual operation, the controller calculates the required airflow distribution based on the temperature data detected by the temperature sensor. Then, the controller sends a control command to the drive mechanism 420. Upon receiving the command, the drive mechanism 420 moves the distributor plate 410 to the desired position. By continuously adjusting the position of the distributor plate 410, precise adjustment of the airflow at the first pipe section 310 can be achieved, thereby optimizing the airflow distribution and improving heat exchange efficiency.

[0065] In this embodiment, the diffuser 410 is movable between a first position and a second position. When the diffuser 410 is moved to the first position, it moves to the air inlet 110, at which point it has virtually no impact on the air blown into the first duct section 310 from the air inlet 110. When the diffuser 410 is moved to the second position, it moves to the edge of the first duct section 310 to block the air blown into the first duct section 310 from the air inlet 110. This arrangement may be used when more precise control of the airflow at the first duct section 310 is required, or in some cases, when airflow into the first duct section 310 may be completely prevented. By moving the diffuser 410 between these two positions, the airflow can be flexibly adjusted to meet different usage requirements.

[0066] An air conditioner provided according to a second aspect embodiment of the present invention, such as Figures 1 to 4 As shown, the air conditioner includes the aforementioned indoor air conditioning unit.

[0067] As a core component of an air conditioner, the performance of the indoor unit directly affects the overall operation of the air conditioner. By introducing an indoor unit with precise airflow control, the air conditioner provided in this embodiment of the invention has significantly improved in terms of heat exchange efficiency, energy consumption control, and operational stability. In this indoor unit, the distributor 40 plays a crucial role. Through the precise coordination of the movable distributor plate 410 and the drive mechanism 420, the distributor 40 can adjust the airflow entering each pipe section according to actual needs. The distributor plate 410 can move between a first position and a second position, a design that allows the air conditioner to flexibly adjust the airflow distribution according to actual requirements. When it is necessary to increase the airflow in the first pipe section 310, the distributor plate 410 moves to the first position; when it is necessary to decrease the airflow in the first pipe section 310, the distributor plate 410 moves to the second position. This precise airflow control helps achieve efficient operation of the air conditioner.

[0068] The control method for an indoor air conditioning unit provided in the third aspect embodiment of the present invention, such as Figure 5 As shown, the process includes the following:

[0069] Step S110: Obtain the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor.

[0070] Step S120: Adjust the splitter based on the first difference between the first temperature and the second temperature to regulate the airflow at the first pipe section.

[0071] After the air conditioner starts working, the controller first acquires the first and second temperatures detected by two temperature sensors (i.e., the first temperature sensor and the second temperature sensor) installed at different locations on the indoor unit. The first temperature is the temperature of the indoor heat exchanger at the first pipe section, and the second temperature is the temperature of the indoor heat exchanger at the second pipe section and / or the third pipe section. These two temperatures are crucial for subsequent airflow adjustment.

[0072] After acquiring the detection data from the two temperature sensors, the controller calculates the first difference between the two temperatures. This difference reflects the unevenness of the temperature distribution inside the indoor unit of the air conditioner. Based on this first difference, the controller intelligently adjusts the operating state of the splitter and changes the position of the splitter plate, thereby regulating the airflow entering the first duct section.

[0073] Specifically, if the difference between the first temperature and the second temperature is large, it indicates that the temperature distribution inside the indoor unit of the air conditioner is relatively uneven. In this case, the controller may adjust the airflow into the first pipe section by adjusting the splitter to balance the temperature distribution and improve heat exchange efficiency. Conversely, if the temperature difference is small, it indicates that the temperature distribution is relatively uniform. The controller may maintain the current state of the splitter or make fine adjustments to maintain this good temperature distribution.

[0074] In this way, the control method of the present invention can precisely adjust the airflow of each pipe section according to the real-time temperature distribution inside the air conditioner indoor unit, thereby achieving a more efficient and energy-saving heat exchange process. This not only improves the performance of the air conditioner indoor unit, but also enhances the user's comfort experience.

[0075] like Figure 6 As shown, step S120: adjusting the splitter based on the first difference between the first temperature and the second temperature to regulate the airflow at the first pipe section includes:

[0076] Step S1210: Determine the first difference between the first temperature and the second temperature.

[0077] Step S1220: Adjust the moving position of the diverter plate based on the first difference and the preset value.

[0078] Step S1230: When the first difference is greater than the preset value, control the splitter plate to move to the second position.

[0079] Step S1240: When the first difference is less than or equal to a preset value, control the diverter plate to move to a preset position between the first position and the second position.

[0080] After the air conditioner is turned on, the controller calculates the first difference between the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor. This difference reflects the temperature difference between different areas of the indoor heat exchanger inside the indoor unit of the air conditioner.

[0081] The controller will then compare this initial difference with a preset value. This preset value is determined based on factors such as the design parameters, performance requirements, and actual operating environment of the indoor air conditioning unit, and is used to determine whether the position of the splitter needs to be adjusted.

[0082] For example, during the cooling process of an air conditioner, if the initial temperature difference is greater than a preset value (e.g., 5 degrees Celsius), it indicates that the temperature at the first pipe section is high, and the airflow in that pipe section needs to be reduced to improve heat exchange efficiency. Therefore, the controller will control the diffuser to move to the first position, the edge of the first pipe section (e.g., moving downwards by 100mm), to block the air blowing from the air inlet towards the first pipe section. This increases the obstruction of airflow to the first pipe section, preventing excessive airflow into it.

[0083] If the first difference is less than or equal to the preset value, it indicates that the temperature in the first duct section is moderate or low, and excessive airflow is not required. In this case, the controller will move the manifold to a preset position between the first and second positions. This preset position is determined based on the absolute value of the first difference, specifically calculated using the formula H = A × |ΔT|. Here, H is the distance between the preset position and the air inlet, A is the adjustment coefficient (e.g., 20), and ΔT is the first difference. This formula ensures that the moving distance is positively correlated with the absolute value of the first difference; that is, the greater the temperature difference, the smaller the downward movement distance of the manifold, thereby increasing the airflow in the first duct section and balancing the airflow across all duct sections.

[0084] In some embodiments, such as Figure 6 As shown, after step S120: adjusting the splitter based on the first difference between the first temperature and the second temperature to regulate the airflow at the first pipe section, the method further includes:

[0085] Step S130: Obtain the third temperature detected by the first temperature sensor and the fourth temperature detected by the second temperature sensor.

[0086] Step S140: Determine the second difference between the third temperature and the fourth temperature, and adjust the position of the manifold based on the preset position.

[0087] After the initial adjustment of the splitter, the controller retrieves temperature information again from the first and second temperature sensors. These temperatures are referred to as the third and fourth temperatures, respectively. This new temperature data reflects the changes in the internal temperature distribution of the air conditioner's indoor unit after the splitter adjustment.

[0088] The controller will then calculate the first difference between the third and fourth temperatures, which is the second difference. This difference reflects the new state of the indoor heat exchanger temperature distribution after the manifold adjustment.

[0089] Based on this second difference, the controller will fine-tune the position of the distributor plate from the previously determined preset position. This fine-tuning is to further optimize the temperature distribution inside the indoor unit of the air conditioner and improve heat exchange efficiency. The specific adjustment strategy can be set according to the actual situation. For example, if the second difference is still large, it means that the temperature distribution is still uneven, and the distributor plate can be further adjusted to reduce the difference; if the second difference is small, it means that the temperature distribution is already relatively uniform, and the current state of the distributor plate can be maintained or fine-tuned.

[0090] Based on the above embodiments, in one embodiment, step S140: determining the second difference between the third temperature and the fourth temperature, and adjusting the position of the manifold based on a preset position, includes:

[0091] Step S1410: Match the temperature range corresponding to the second difference.

[0092] Step S1420: Based on the adjustment distance corresponding to the temperature range, move the basic control diverter plate at the preset position.

[0093] Specifically, in this step, the controller first determines the temperature range to which the second difference belongs based on its magnitude. These temperature ranges are pre-set, and each range corresponds to a specific adjustment distance. The advantage of this approach is that it allows for the rapid determination of the appropriate adjustment strategy based on the range of temperature differences, avoiding the complex calculation process for each specific difference.

[0094] The temperature range can be adjusted according to actual needs. For example, a smaller temperature range can be set to achieve more precise control, or a larger temperature range can be set to simplify the control logic. The adjustment distance for each temperature range is also determined based on factors such as the design parameters, performance requirements, and actual operating environment of the indoor air conditioning unit, aiming to achieve optimal heat exchange and energy efficiency.

[0095] After determining the temperature range to which the second difference belongs, the controller will look up the corresponding adjustment distance for that range. This adjustment distance indicates how much adjustment is needed to the position of the shunt under the current temperature distribution.

[0096] Then, the controller adds this adjustment distance to the previously determined preset position to obtain a new moving position, and controls the distributor plate to move to this new position. In this way, the position of the distributor can be precisely adjusted according to the real-time temperature distribution to further optimize the heat exchange effect of the indoor unit of the air conditioner.

[0097] In this way, the control method enables precise control of the internal temperature distribution of the air conditioner's indoor unit. By matching temperature ranges and corresponding adjustment distances, a suitable adjustment strategy can be quickly determined, and fine-tuning can be performed based on preset positions to ensure that the indoor unit maintains efficient heat exchange under different operating conditions. This not only improves energy efficiency but also enhances the user experience.

[0098] It should be noted that the adjustment distance is positively correlated with the absolute value of the second difference. For example, during the cooling process of an air conditioner, the initial distance from the air outlet is H mm.

[0099] If the second difference is detected to be ≤0.5℃, the corresponding adjustment distance is 0, and the distance at this time remains at α.

[0100] If 0.5℃ < the second difference ≤ 1℃ is detected, the corresponding adjustment distance is 1mm, then the distance is adjusted to H+1mm.

[0101] If it is detected that 1℃ < the second difference ≤ 2℃, the corresponding adjustment distance is 3mm, then the distance adjustment at this time is H+3.

[0102] If 2℃ < the second difference ≤ 3℃ is detected, the corresponding adjustment distance is 5mm, then the distance adjustment at this time is H+5.

[0103] If the detected temperature is 3℃ < second difference ≤ 4℃, the corresponding adjustment distance is 7mm, then the distance adjustment is H+7.

[0104] If 4℃ < the second difference ≤ 5℃ is detected, the corresponding adjustment distance is 9mm, then the distance adjustment at this time is H+9.

[0106] The acquisition module 710 is used to acquire the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor.

[0107] The adjustment module 720 is used to adjust the splitter based on the first difference between the first temperature and the second temperature to adjust the air volume at the first pipe section.

[0108] It should be noted that steps S110 to S120 and other steps are for ease of description only and do not constitute a time sequence limitation for the control method of the indoor unit of the air conditioner. Furthermore, some content is described in detail in the control method provided in the third aspect embodiment, and all content in the control method is also applicable to the embodiments provided in the fourth aspect embodiment.
