Background Technology

[0002] As people's living standards improve, their focus on air conditioners has shifted beyond just capacity and energy efficiency; they also increasingly demand greater comfort. For round, floor-standing air conditioners, uneven refrigerant distribution in the upper and lower airflow paths leads to complaints about poor uniformity of the outlet air temperature, impacting user comfort.

By setting an auxiliary electric heating block on the basis of the air conditioner's electric heating module, and controlling the position of the auxiliary electric heating block according to the air outlet temperature and the indoor ambient temperature, the uniformity of the air outlet temperature of the air conditioner is improved, thereby enhancing the user's comfort experience.

[0011] In conjunction with the above-described device, the present invention further provides an air conditioner, comprising: the air outlet temperature control device of the air conditioner described above.

[0012] In conjunction with the aforementioned air conditioner, the present invention further provides an air conditioner control method, comprising: upon receiving a heating start command from the air conditioner, controlling the air conditioner to start and operate in heating mode; during the heating operation of the air conditioner, sampling the outlet air temperature at each of the n outlet grilles to obtain the outlet air temperature of the n outlet grilles; and sampling the indoor ambient temperature of the room where the air conditioner is located, recording it as the indoor ambient temperature of the air conditioner; and controlling the opening and closing of the auxiliary electric heating block and the movement of the auxiliary electric heating block based on the outlet air temperature of the n outlet grilles and the indoor ambient temperature of the air conditioner, so as to achieve overall adjustment of the uniformity of the outlet air temperature of the air conditioner.

[0013] In some embodiments, controlling the opening and closing of the auxiliary electric heating block and controlling whether the auxiliary electric heating block moves, based on the outlet air temperatures of the n air outlet grilles and the indoor ambient temperature of the air conditioner, includes: determining the lowest and second lowest temperatures among the outlet air temperatures of the n air outlet grilles; recording the lowest temperature among the outlet air temperatures of the n air outlet grilles as the lowest outlet air temperature of the air conditioner, and recording the second lowest temperature among the outlet air temperatures of the n air outlet grilles as the second lowest outlet air temperature of the air conditioner; after removing the highest and lowest temperatures among the outlet air temperatures of the n air outlet grilles, determining the average of the remaining n-2 outlet air temperatures as the first outlet air temperature of the air conditioner. The system determines the indoor ambient temperature range of the air conditioner and, based on the correspondence between the set indoor ambient temperature range and the set second outlet air temperature threshold, determines the set outlet air temperature threshold corresponding to the set indoor ambient temperature range that is the same as the indoor ambient temperature range of the air conditioner, as the second outlet air temperature threshold corresponding to the indoor ambient temperature range of the air conditioner, and records it as the second outlet air temperature threshold of the air conditioner; and, in combination with the lowest outlet air temperature of the air conditioner, the second lowest outlet air temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first outlet air temperature threshold of the air conditioner, and the second outlet air temperature threshold of the air conditioner, controls the opening and closing of the auxiliary electric heating block and controls whether the auxiliary electric heating block moves.

[0014] In some embodiments, when the auxiliary electric heating block includes a first electric heating block and a second electric heating block, the opening and closing of the auxiliary electric heating block and the movement of the auxiliary electric heating block are controlled by combining the lowest air outlet temperature of the air conditioner, the second lowest air outlet temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first air outlet temperature threshold of the air conditioner, and the second air outlet temperature threshold of the air conditioner. This includes: determining whether the lowest air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold of the air conditioner, and the second lowest air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold of the air conditioner; if these conditions are met, the first electric heating block is turned on, and the first electric heating block is moved to a first position on the moving module. Simultaneously, the second electric heating block is controlled to turn on and move to a second position on the moving module; wherein, the first position on the moving module is a position on the moving module that is flush with the air outlet grille corresponding to the lowest air outlet temperature of the air conditioner; the second position on the moving module is a position on the moving module that is flush with the air outlet grille corresponding to the second lowest air outlet temperature of the air conditioner; if the conditions are not met, then if the lowest air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold of the air conditioner, and the second lowest air outlet temperature of the air conditioner is greater than the first air outlet temperature threshold of the air conditioner, the first electric heating block is controlled to turn on and move to the first position on the moving module.

[0015] In some implementations, controlling the opening and closing of the auxiliary electric heating block and controlling its movement, in conjunction with the lowest outlet air temperature, the second lowest outlet air temperature, the indoor ambient temperature, the first outlet air temperature threshold, and the second outlet air temperature threshold of the air conditioner, further includes: after controlling the first electric heating block to turn on and move it to a first position on the moving module, determining whether the conditions are met: the lowest outlet air temperature of the air conditioner is greater than or equal to the first outlet air temperature threshold, and the absolute value of the temperature difference between the indoor ambient temperature and the lowest outlet air temperature is less than or equal to the second outlet air temperature threshold; if met, controlling the first electric heating block to turn off; if not met, controlling the first electric heating block to continue heating, and then returning to re-determine whether the conditions are met again: the lowest outlet air temperature of the air conditioner is greater than or equal to the first outlet air temperature threshold, and the absolute value of the temperature difference between the indoor ambient temperature and the lowest outlet air temperature is less than or equal to the second outlet air temperature threshold. The method includes: controlling the opening and closing of the auxiliary electric heating block and controlling the movement of the auxiliary electric heating block, in conjunction with the lowest air outlet temperature of the air conditioner, the second lowest air outlet temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first air outlet temperature threshold of the air conditioner, and the second air outlet temperature threshold of the air conditioner. This further includes: after controlling the second electric heating block to turn on and moving it to the second position on the moving module, determining whether the second lowest air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the second lowest air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner; if satisfied, controlling the second electric heating block to turn off; if not satisfied, controlling the second electric heating block to continue heating, and then returning to re-determine whether the second lowest air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the second lowest air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0016] Therefore, the solution of the present invention, for air conditioners with electric heating modules (such as round vertical cabinet air conditioners), adds a slide rail (such as a slide rail 4 for auxiliary electric heating blocks) and auxiliary electric heating blocks (such as a first electric heating block 3 and a second electric heating block 5) to the air conditioner's own electric heating module (such as the main electric heater 2); according to the air conditioner's outlet air temperature and the indoor ambient temperature, the auxiliary electric heating blocks are controlled to move on the slide rail to change the position of the auxiliary electric heating blocks at the air conditioner's outlet air temperature to adjust the air conditioner's outlet air temperature; thus, by setting auxiliary electric heating blocks on the basis of the air conditioner's electric heating module, and controlling the position of the auxiliary electric heating blocks according to the air conditioner's outlet air temperature and the indoor ambient temperature, it is beneficial to improve the uniformity of the air conditioner's outlet air temperature and enhance the user's comfort experience.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0033] Considering that for air conditioners (such as round floor-standing units), uneven distribution of refrigerant in the upper and lower airflow paths leads to poor uniformity of the outlet air temperature, affecting user comfort, a related solution provides an electric heating module consisting of multiple parallel PTC (Positive Temperature Coefficient) electric heaters and fixed components. Each electric heater corresponds to one air outlet, and the system adjusts the operating power of each electric heater according to the outlet air temperature. However, this control method involves independent control of multiple electric heaters, making the control process relatively complex. Furthermore, the electric heating module in this solution is composed of multiple small electric heating blocks connected in parallel to form a large electric heating block, resulting in a complex assembly structure. While the individual parallel control of multiple electric heaters is relatively intelligent, it involves many electronic components and a complex control program.

[0034] Therefore, the present invention proposes an air conditioner outlet temperature control device, specifically an electric heating control device for improving the uniformity of air conditioner outlet temperature. For air conditioners with an electric heating module (such as a round vertical cabinet unit), based on the air conditioner's own electric heating module (such as the main electric heater 2), a slide rail (such as a slide rail 4 for an auxiliary electric heating block) and auxiliary electric heating blocks (such as a first electric heating block 3 and a second electric heating block 5) are added. The auxiliary electric heating blocks can move on the slide rail to change their position at the air conditioner outlet. By combining the air conditioner outlet temperature and the indoor ambient temperature, controlling the position of the auxiliary electric heating blocks at the air conditioner outlet helps improve the uniformity of the air conditioner outlet temperature.

[0035] According to an embodiment of the present invention, an air outlet temperature control device for an air conditioner is provided. See also... Figure 1 The diagram shows a structural schematic of an embodiment of the device of the present invention. The air conditioner has an indoor unit, in which an electric heating module is installed. An air outlet grille is installed at the air outlet of the indoor unit. Specifically, an electric heating module (such as a main electric heater 2) is installed in the air duct of the indoor unit, and an air outlet grille is installed at the air outlet of the air duct of the indoor unit. The number of air outlet grilles is n, and a temperature sensor is installed at each air outlet grille, where n is a positive integer. A moving module is installed on the electric heating module along its length. An auxiliary electric heating block can move on the moving module to change its position on the moving module, thereby changing the heating position of the auxiliary electric heating module at the air outlet of the air conditioner. The air outlet temperature control device of the air conditioner includes a sampling unit and a control unit.

[0036] The control unit is configured to control the air conditioner to start and operate in heating mode upon receiving a heating start command from the air conditioner.

[0037] The sampling unit is configured to sample the air outlet temperature at each of the n air outlet grilles during the heating operation of the air conditioner, such as by sampling the air outlet temperature at each air outlet grille using a temperature sensor installed at each air outlet grille, thereby obtaining the air outlet temperatures of the n air outlet grilles; and to sample the indoor ambient temperature of the room where the air conditioner is located, and record it as the indoor ambient temperature of the air conditioner.

[0038] The control unit is further configured to control the opening and closing of the auxiliary electric heating block and the movement of the auxiliary electric heating block based on the outlet air temperature of the n outlet grilles and the indoor ambient temperature of the air conditioner, so as to achieve overall adjustment of the uniformity of the outlet air temperature of the air conditioner.

[0039] The electric heating control device proposed in this invention for improving the uniformity of air outlet temperature of an air conditioner is designed for air conditioners with electric heating modules (such as round vertical cabinet air conditioners). Based on the air conditioner's own electric heating module (such as the main electric heater 2), a moving module such as a slide rail (i.e., the slide rail 4 of the auxiliary electric heating block) and auxiliary electric heating blocks (such as the first electric heating block 3 and the second electric heating block 5) are added. This improves the uniformity of the air outlet temperature of the air conditioner without changing the structure of the original electric heating module, ensuring the universality of the air conditioner's electric heating module and helping to reduce energy consumption.

[0040] In some embodiments, the moving module includes: a sliding component, such as a slide rail 4; the auxiliary electric heating block includes: a first electric heating block 3 and a second electric heating block 5. Wherein, when the electric heating module is placed vertically, the number of sliding components is two, each comprising a first slide rail and a second slide rail, the first and second slide rails being respectively disposed on the left and right sides of the electric heating module; the first electric heating block 3 is disposed on the first slide rail and can slide on the first slide rail to achieve movement; the second electric heating block 5 is disposed on the second slide rail and can slide on the second slide rail to achieve movement. Wherein, both the first and second slide rails can be slide rail 4.

[0041] Specifically, Figure 3 This is a schematic diagram of the structure of an embodiment of the electric heating device for an air conditioner according to the present invention. Figure 4 This is a schematic diagram of another embodiment of the electric heating device for the air conditioner of the present invention. Figure 3 and Figure 4 As shown, in the present invention, slide rails 4, a first electric heating block 3, and a second electric heating block 5 are added to the left and right sides of the air conditioner's own electric heating module (such as the main electric heater 2). Both the first electric heating block 3 and the second electric heating block 5 are mounted on the slide rails 4 and can slide on the slide rails 4 to change the position of the first electric heating block 3 and / or the second electric heating block 5 at the air outlet of the air conditioner, specifically changing the position of the first electric heating block 3 and / or the second electric heating block 5 within the multiple air outlet grilles of the air conditioner. The main electric heater 2, the slide rails 4, and the first electric heating block 3 and the second electric heating block 5 form the electric heating device of the air conditioner in the present invention.

[0042] The air conditioner itself includes an electric heating module, such as the main electric heater 2, which has a fixed end 1. Specifically, slide rails 4, a first electric heating block 3, and a second electric heating block 5 are added to the left and right sides of the fixed end 1 of the main electric heater. The fixed end 1 of the main electric heater 2 contains screw holes, through which the slide rails 4 can be installed.

[0043] Figure 6This is a schematic diagram of the structure of the main electric heater and slide rail in an embodiment of the electric heating device of the air conditioner of the present invention. Figure 6 As shown, in implementing the solution of the present invention, the fixed end 1 of the main electric heater 2 of the air conditioner is made wider, such as leaving a margin of 1cm to 2cm on the left and right sides of the fixed end 1 of the main electric heater 2, so as to add slide rails 4 of auxiliary electric heating blocks at the left and right ends of the fixed end 1 of the main electric heater 2 and fix them by screw holes.

[0044] In some embodiments, a first rolling wheel is provided at the connection between the first electric heating block 3 and the first slide rail; the first rolling wheel is disposed in the slide groove of the first slide rail and can roll in the slide groove of the first slide rail to adapt and adjust the relative angle between the first electric heating block 3 and the electric heating module according to the indoor heat exchanger in the indoor unit; the first electric heating block 3 is connected to the first rolling wheel through a first connecting rod.

[0045] Similarly, a second rolling wheel is provided at the connection between the second electric heating block 5 and the second slide rail; the second rolling wheel is disposed in the slide groove of the second slide rail and can roll in the slide groove of the second slide rail to adapt and adjust the relative angle between the second electric heating block 5 and the electric heating module according to the indoor heat exchanger in the indoor unit; the second electric heating block 5 is connected to the second rolling wheel through a second connecting rod. Both the first rolling wheel and the second rolling wheel can be spherical rolling wheels 6.

[0046] Figure 5 This is a schematic diagram of an embodiment of the auxiliary heating block and slide rail in the electric heating device of the air conditioner of the present invention. Figure 5 As shown, both the first electric heating block 3 and the second electric heating block 5 are connected to the support rod by spherical rolling wheels 6. In the solution of the present invention, the rolling wheels are designed to be spherical and can roll within the slide rail 4. The angle of the auxiliary electric heating block can be adjusted according to the shape of different indoor heat exchangers (it can be manually adjusted during installation) to avoid problems such as the auxiliary electric heating block touching the fins of the indoor heat exchanger and thus affecting the heat exchange of the system.

[0047] In this invention, the auxiliary electric heating block is designed to be angle-adjustable to adapt to the shape of different indoor heat exchangers. While some designs only allow the heating block to move vertically, this invention allows the auxiliary electric heating block to move not only vertically but also to change its horizontal position by adjusting its angle, thus adapting to the shape of different heat exchangers.

[0048] In some embodiments, the control unit controls the opening and closing of the auxiliary electric heating block and the movement of the auxiliary electric heating block based on the outlet air temperature of the n air outlet grilles and the indoor ambient temperature of the air conditioner, including:

[0049] The control unit is further configured to determine the lowest and second lowest temperatures among the n air outlet temperatures of the n air outlet grilles, record the lowest temperature among the n air outlet temperatures as the lowest air outlet temperature of the air conditioner, and record the second lowest temperature among the n air outlet temperatures as the second lowest air outlet temperature of the air conditioner, such as air outlet temperature T1 and air outlet temperature T2.

[0050] The control unit is further configured to remove the highest and lowest temperatures from the outlet temperatures of the n outlet grilles, and then determine the average value of the outlet temperatures of the remaining n-2 outlet grilles as the first outlet temperature threshold of the air conditioner, such as temperature threshold A1.

[0051] The control unit is further configured to determine the range of indoor ambient temperature of the air conditioner; and, based on the correspondence between the set indoor ambient temperature range and the set second air outlet temperature threshold, determine the set air outlet temperature threshold corresponding to the set indoor ambient temperature range that is the same as the range of indoor ambient temperature of the air conditioner in the correspondence as the second air outlet temperature threshold corresponding to the range of indoor ambient temperature of the air conditioner, and denoted as the second air outlet temperature threshold of the air conditioner, such as temperature threshold Bi.

[0052] The control unit is further configured to control the opening and closing of the auxiliary electric heating block and to control whether the auxiliary electric heating block moves, in conjunction with the lowest air outlet temperature of the air conditioner, the second lowest air outlet temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first air outlet temperature threshold of the air conditioner, and the second air outlet temperature threshold of the air conditioner.

[0053] Figure 2 This is a schematic flowchart illustrating an embodiment of a control method for an electric heating device used to improve the uniformity of airflow from an air conditioner according to the present invention. Figure 2 As shown, the present invention proposes a control method for an electric heating device for improving the uniformity of airflow from an air conditioner, comprising:

[0054] Step 1: Obtain the two lower air outlet temperatures from all air outlet grilles of the air conditioner, denoted as air outlet temperature T1 and air outlet temperature T2; and obtain the indoor ambient temperature of the air conditioner, then proceed to Step 2.

[0055] In step 1, to obtain the air outlet temperatures T1 and T2 of the air conditioner, a temperature sensor is installed on each air outlet grille of the air conditioner. Due to differences in duct design between different models, the temperature sensors are positioned directly opposite the air outlet to detect the outlet temperature. Within two hours of the user remotely turning on the air conditioner for heating mode, the air conditioner's control system reads the temperature from each sensor every 5 minutes. Assuming there are n temperature sensors, where n is a positive integer, the temperatures from each sensor, from largest to smallest, are Tn, Tn-1, ..., T2, T1, thus obtaining the air outlet temperatures T1 and T2.

[0056] Step 2: Determine the temperature threshold A1 and temperature threshold Bi, where i is a positive integer, and then proceed to step 3.

[0057] In step 2, when determining the temperature threshold A1, specifically: given that the temperatures of each temperature sensor are obtained in descending order as Tn, Tn-1, ..., T2, T1, except for T1 and Tn, the average value of the temperature of each temperature sensor is determined as the temperature threshold A1, that is, temperature threshold A1 = (Tn-1 + Tn-2 + ... + T3 + T2) / (n-2).

[0058] In step 2, determining the temperature threshold Bi specifically involves considering the temperature difference between the lowest acceptable outlet air temperature and the indoor ambient temperature at different indoor ambient temperatures. In other words, the temperature threshold Bi varies depending on the indoor ambient temperature (as shown in the table below). Furthermore, because different groups of people can tolerate different minimum outlet air temperatures, the indoor ambient temperature also varies depending on the user group.

[0059] The emphasis here on the varying temperature difference between the minimum acceptable outlet air temperature and the indoor ambient temperature, under different indoor temperatures, is primarily to ensure a comfortable thermal experience for the human body. For example, if the space where the air conditioner is located has open windows or doors, or if the room is large, the indoor temperature rises too slowly. Even if only T1≥A1 or only T2≥A1 is satisfied, the actual temperature perceived by the human body may still be quite cold. Therefore, the Bi value is necessary. Determining the Bi value takes into account the impact of the temperature difference between the minimum acceptable outlet air temperature and the indoor ambient temperature. A suitable Bi value needs to be determined based on this temperature difference to improve the human body's thermal comfort experience.

[0060]

[0061] For example: If the indoor ambient temperature is less than 0℃, then Bi is B1; if the indoor ambient temperature is greater than or equal to 0℃ and less than or equal to 5℃, then Bi is B2; if the indoor ambient temperature is greater than 5℃ and less than or equal to 10℃, then Bi is B3; if the indoor ambient temperature is greater than 10℃ and less than or equal to 15℃, then Bi is B4; if the indoor ambient temperature is greater than 15℃ and less than or equal to 20℃, then Bi is B5; if the indoor ambient temperature is greater than 20℃, then Bi is B6. For example: the value of B1 can be 30℃~35℃; the value of B2 can be 25℃~30℃; the value of B3 can be 20℃~25℃; the value of B4 can be 15℃~20℃; the value of B5 can be 10℃~15℃; and the value of B6 can be 5℃~10℃. For B1, B2, and B3, since the indoor ambient temperature is low at this time, the temperature of the hot air blown out by the air conditioner is mixed with the indoor ambient temperature before being delivered to the human activity area. The temperature that the human body can feel from the air conditioner is somewhat reduced compared to the temperature of the hot air blown out by the air conditioner. Therefore, a higher B1, B2, and B3 value is required to ensure the human body's thermal comfort experience.

[0062] In practical use, the appropriate values ​​for B1 to B6 can be selected based on the body's heat production rate. For example, for the elderly and children, whose metabolism and heat production are slower, the upper limit of the B1 to B6 values ​​can be used; for young adults, whose metabolism and heat production are faster, the lower limit of the B1 to B6 values ​​can be used.

[0063] In some embodiments, when the auxiliary electric heating block includes a first electric heating block 3 and a second electric heating block 5, the control unit, in conjunction with the lowest outlet air temperature of the air conditioner, the second lowest outlet air temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first outlet air temperature threshold of the air conditioner, and the second outlet air temperature threshold of the air conditioner, controls the opening and closing of the auxiliary electric heating block and controls whether the auxiliary electric heating block moves, including: a first process of controlling the auxiliary electric heating block, specifically as follows:

[0064] The control unit is further configured to determine whether the minimum air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold of the air conditioner, and the second lowest air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold of the air conditioner.

[0065] The control unit is further configured to, if the conditions are met, control the first electric heating block 3 to turn on and control the first electric heating block 3 to move to a first position on the moving module; simultaneously, control the second electric heating block 5 to turn on and control the second electric heating block 5 to move to a second position on the moving module; wherein, the first position on the moving module is a position on the moving module that is flush with the air outlet grille corresponding to the lowest air outlet temperature of the air conditioner; the second position on the moving module is a position on the moving module that is flush with the air outlet grille corresponding to the second lowest air outlet temperature of the air conditioner.

[0066] The control unit is further configured to, if the conditions are not met, control the first electric heating block 3 to turn on and move it to a first position on the moving module when the lowest air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold and the second lowest air outlet temperature is greater than the first air outlet temperature threshold. Conversely, if neither the conditions are met (the lowest air outlet temperature is less than or equal to the first air outlet temperature threshold and the second lowest air outlet temperature is greater than the first air outlet temperature threshold), the air conditioner will maintain its current operation, i.e., the first electric heating block 3 will remain off, and the second electric heating block 5 will remain off.

[0067] In some embodiments, the control unit, in conjunction with the lowest outlet air temperature of the air conditioner, the second lowest outlet air temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first outlet air temperature threshold of the air conditioner, and the second outlet air temperature threshold of the air conditioner, controls the opening and closing of the auxiliary electric heating block and controls whether the auxiliary electric heating block moves. The control unit further includes a second process for controlling the auxiliary electric heating block, as follows:

[0068] The control unit is further configured to, after controlling the first electric heating block 3 to turn on and controlling the first electric heating block 3 to move to the first position on the moving module, determine whether the minimum air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the minimum air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0069] The control unit is further configured to control the first electric heating block 3 to turn off if the condition is met.

[0070] The control unit is further configured to, if not satisfied, control the first electric heating block 3 to continue heating, and then return to re-determine whether the minimum air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the minimum air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0071] In some embodiments, the control unit, in conjunction with the lowest outlet air temperature of the air conditioner, the second lowest outlet air temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first outlet air temperature threshold of the air conditioner, and the second outlet air temperature threshold of the air conditioner, controls the opening and closing of the auxiliary electric heating block and controls whether the auxiliary electric heating block moves. The control unit also includes a third process for controlling the auxiliary electric heating block, as follows:

[0072] The control unit is further configured to, after controlling the second electric heating block 5 to turn on and controlling the second electric heating block 5 to move to the second position on the moving module, determine whether the conditions are met: the second lowest air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the second lowest air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0073] The control unit is further configured to control the second electric heating block 5 to turn off if the condition is met.

[0074] The control unit is further configured to, if not satisfied, control the second electric heating block 5 to continue heating, and then return to re-determine whether the conditions are met: the second lowest air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the second lowest air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0075] Specifically, such as Figure 2 As shown, the present invention proposes a control method for an electric heating device for improving the uniformity of airflow from an air conditioner, which further includes:

[0076] Step 3: Determine whether the conditions of outlet air temperature T1 ≤ temperature threshold A1 and outlet air temperature T2 ≤ temperature threshold A1 are met. If yes, proceed to step 4; otherwise, proceed to step 5.

[0077] Step 4: If the detected air outlet temperature T1 ≤ temperature threshold A1 and the detected air outlet temperature T2 ≤ temperature threshold A1, then the first electric heating block and the second electric heating block are turned on. The first electric heating block 3 moves to the spatial height corresponding to the temperature sensor that detected the air outlet temperature T1, and the second electric heating block 5 moves to the spatial height corresponding to the temperature sensor that detected the air outlet temperature T2. Then, step 41 is executed.

[0078] For a round, upright cabinet air conditioner, the first electric heating block 3 needs to move up and down to the height of the space corresponding to the temperature sensor for outlet air temperature T1, and the second electric heating block 5 needs to move to the height of the space corresponding to the temperature sensor for detecting outlet air temperature T2. Specifically, controlling the movement of the first electric heating block 3 to the height of the temperature sensor for outlet air temperature T1 and the second electric heating block 5 to the height of the temperature sensor for detecting outlet air temperature T2 can be achieved by using an infrared receiver mounted on a spherical rolling wheel 6. This receiver receives signals from the air conditioner's main board and drives the movement of each auxiliary electric heating block accordingly.

[0079] The specific method for controlling the movement of the first electric heating block 3 and the second electric heating block 5 can be as follows: a drive mechanism (such as a small stepper motor) can be installed inside the spherical rolling wheels 6 corresponding to the first electric heating block 3 and the second electric heating block 5. This drive mechanism drives the corresponding spherical rolling wheels 6 to roll, thereby achieving the movement of the first electric heating block 3 and / or the second electric heating block 5. For example, after receiving the drive signal sent by the air conditioner mainboard, the infrared receiver arranged on the spherical rolling wheel 6 controls the small stepper motor arranged inside the spherical rolling wheel 6 to start, thereby achieving the movement of each auxiliary electric heating block, such as the movement of the first electric heating block 3 and / or the second electric heating block 5.

[0080] Step 41: After the auxiliary electric heating block is turned on, the air conditioning control system determines every 2 minutes whether the following conditions are met: outlet air temperature T1 ≥ temperature threshold A1 and |T inner ring - outlet air temperature T1| ≤ temperature threshold Bi, and outlet air temperature T2 ≥ temperature threshold A1 and |T inner ring - outlet air temperature T2| ≤ temperature threshold Bi. If neither condition is met, the corresponding electric heating block continues to heat up; if both conditions are met, the corresponding electric heating block stops heating up; if either condition is met, the electric heating block corresponding to the temperature sensor whose temperature does not meet the requirement continues to heat up, while the electric heating block corresponding to the temperature sensor whose temperature meets the requirement stops heating up.

[0081] Step 5: If the detected air outlet temperature T1 ≤ temperature threshold A1 and the detected air outlet temperature T2 > temperature threshold A1, then the first electric heating block is turned on, the first electric heating block 3 moves to the height of the space corresponding to the temperature sensor that detected the air outlet temperature T1, and then step 51 is executed.

[0082] Step 51: After the first electric heating block is turned on, the air conditioner control system determines every 2 minutes whether the outlet air temperature T1 ≥ temperature threshold A1 and |T inner ring - outlet air temperature T1| ≤ temperature threshold Bi. If not satisfied, the first electric heating block continues to heat up; if satisfied, the first electric heating block stops heating up.

[0083] In this invention, a slide rail (such as slide rail 4 for auxiliary electric heating blocks) and auxiliary electric heating blocks (such as first electric heating block 3 and second electric heating block 5) are added to the air conditioner's own electric heating module. By detecting the temperature of each air outlet, and based on the electric heater temperature, indoor ambient temperature, and the average temperature of each temperature sensor, when judging the air conditioner's outlet temperature, only the two lower outlet temperatures, namely outlet temperature T1 and outlet temperature T2, are judged. The remaining n-2 outlet temperatures are not judged. The lower-temperature outlets are heated by the auxiliary electric heating blocks. Combined with the human body's acceptable temperature difference (such as considering the human body's acceptable temperature difference when determining the Bi value), the uniformity of the overall air conditioner outlet temperature is further ensured. Specifically, the temperature control of each electric heater in the first electric heating block 3 and the second electric heating block 5 can be achieved by adjusting the power of the corresponding electric heater to regulate its temperature.

[0084] Some solutions increase the air outlet temperature of the air conditioner simply by increasing the operating power of its built-in electric heater, aiming to solve the problem of low air outlet temperature. However, since this electric heater is a single unit, increasing the operating power raises the temperature of all air outlet grilles, but the problem of large temperature differences between grilles and uneven air outlet temperature persists—that is, the temperature is high in the middle and low at the top and bottom. The solution of this invention adds auxiliary electric heating blocks to the existing electric heating module of the air conditioner. These auxiliary electric heating blocks are placed at the locations of the air outlet grilles where the air outlet temperature is low, thereby improving the overall uniformity of the air outlet temperature. This aims to solve the problem of large temperature differences between the air outlet grilles, especially the poor uniformity of the heating air outlet.

[0085] In some solutions, the electric heating module of the air conditioner increases its operating power to accommodate air outlets with lower outlet temperatures, resulting in higher energy consumption. For example, for an integrated electric heater, if the system detects a lower temperature at a particular air outlet, it increases the operating power of the entire heater, but temperature differences still exist between the air outlets, leading to poor air temperature uniformity and high energy consumption. The solution of this invention is to install sliding auxiliary electric heating blocks on both sides of the integrated electric heater. By adjusting these auxiliary heating blocks, the uniformity of air outlet temperature at each air outlet is ensured, while simultaneously reducing air conditioner energy consumption.

[0086] The air conditioner adopts the electric heating control method of the present invention. By adding a slide rail (such as the slide rail 4 of the auxiliary electric heating block) and an auxiliary electric heating block (such as the first electric heating block 3 and the second electric heating block 5) to the air conditioner's own electric heating module, the temperature of the air outlet with a lower air temperature (that is, the temperature of the air outlet grille with a lower air temperature) can be increased, reducing the overall air outlet temperature difference of the machine by 5% to 15%, ensuring the uniformity of the air outlet temperature of each air outlet grille, and improving the user's comfort experience.

[0087] By employing the technical solution of this invention, for air conditioners with electric heating modules (such as round vertical cabinet air conditioners), a slide rail (such as a slide rail 4 for auxiliary electric heating blocks) and auxiliary electric heating blocks (such as a first electric heating block 3 and a second electric heating block 5) are added to the air conditioner's own electric heating module (such as a main electric heater 2). Based on the air conditioner's outlet air temperature and the indoor ambient temperature, the auxiliary electric heating blocks are controlled to move on the slide rail to change their position at the air conditioner's outlet, thereby adjusting the air conditioner's outlet air temperature. Therefore, by setting auxiliary electric heating blocks on the basis of the air conditioner's electric heating module, and controlling the position of the auxiliary electric heating blocks according to the air conditioner's outlet air temperature and the indoor ambient temperature, it is beneficial to improve the uniformity of the air conditioner's outlet air temperature and enhance the user's comfort experience.

[0088] According to an embodiment of the present invention, an air conditioner corresponding to an air outlet temperature control device for an air conditioner is also provided. This air conditioner may include: the air outlet temperature control device for an air conditioner as described above.

[0089] Since the processing and functions implemented by the air conditioner in this embodiment are basically corresponding to the embodiments, principles and examples of the device, any details not covered in the description of this embodiment can be found in the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0090] By adopting the technical solution of the present invention, for air conditioners with electric heating modules (such as round vertical cabinet air conditioners), based on the air conditioner's own electric heating module (such as the main electric heater 2), a slide rail (such as the slide rail 4 for auxiliary electric heating blocks) and auxiliary electric heating blocks (such as the first electric heating block 3 and the second electric heating block 5) are added; according to the air conditioner's outlet air temperature and the indoor ambient temperature, the movement of the auxiliary electric heating blocks on the slide rail is controlled to change the position of the auxiliary electric heating blocks at the air conditioner's outlet to adjust the air conditioner's outlet air temperature; while improving the uniformity of the air conditioner's outlet air temperature, the original structure of the air conditioner's electric heating module is not changed, ensuring the universality of the air conditioner's electric heating module and helping to reduce energy consumption.

[0091] According to embodiments of the present invention, an air conditioning control method corresponding to an air conditioner is also provided, such as... Figure 7 The diagram shows a flowchart of an embodiment of the method of the present invention. The air conditioner control method may include steps S110 to S130.

[0092] In step S110, upon receiving the heating start command of the air conditioner, the air conditioner is controlled to start and operate in heating mode.

[0093] In step S120, during the heating operation of the air conditioner, the air outlet temperature of each of the n air outlet grilles is sampled, such as by sampling the air outlet temperature of each air outlet grille through a temperature sensor set at each air outlet grille, to obtain the air outlet temperature of the n air outlet grilles; and the indoor ambient temperature of the room where the air conditioner is located is sampled and recorded as the indoor ambient temperature of the air conditioner.

[0094] In step S130, the opening and closing of the auxiliary electric heating block is controlled according to the air outlet temperature of the n air outlet grilles and the indoor ambient temperature of the air conditioner, and the movement of the auxiliary electric heating block is also controlled, so as to achieve overall adjustment of the uniformity of the air outlet temperature of the air conditioner.

[0095] The electric heating control method proposed in this invention for improving the uniformity of air conditioning air outlet is designed for air conditioners with electric heating modules (such as round vertical cabinet air conditioners). Based on the air conditioner's own electric heating module (such as the main electric heater 2), a moving module such as a slide rail (i.e., the slide rail 4 of the auxiliary electric heating block) and auxiliary electric heating blocks (such as the first electric heating block 3 and the second electric heating block 5) are added. By combining the air conditioner's outlet air temperature and the indoor ambient temperature, the position of the auxiliary electric heating blocks at the air conditioner's outlet is controlled. This improves the uniformity of the air conditioner's outlet air temperature without changing the structure of the air conditioner's original electric heating module, ensuring the universality of the air conditioner's electric heating module and helping to reduce energy consumption.

[0096] In some embodiments, the specific process of controlling the opening and closing of the auxiliary electric heating block and controlling whether the auxiliary electric heating block moves in step S130 based on the air outlet temperature of the n air outlet grilles and the indoor ambient temperature of the air conditioner is described in the following exemplary description.

[0097] The following is combined Figure 8 The schematic diagram shown is a flowchart of an embodiment of the method of the present invention, which controls the auxiliary electric heating block according to the outlet air temperature of the n outlet air grilles and the indoor ambient temperature. The specific process of controlling the auxiliary electric heating block according to the outlet air temperature of the n outlet air grilles and the indoor ambient temperature in step S130 is further explained, including steps S210 to S240.

[0098] Step S210: For the outlet temperatures of the n outlet grilles, determine the lowest and second lowest temperatures among the outlet temperatures of the n outlet grilles. Record the lowest temperature among the outlet temperatures of the n outlet grilles as the lowest outlet temperature of the air conditioner, and record the second lowest temperature among the outlet temperatures of the n outlet grilles as the second lowest outlet temperature of the air conditioner. The lowest outlet temperature is like outlet temperature T1, and the second lowest outlet temperature is like outlet temperature T2.

[0099] Step S220: After removing the highest and lowest temperatures from the n air outlet temperatures, the average value of the remaining n-2 air outlet temperatures is determined as the first air outlet temperature threshold of the air conditioner, such as temperature threshold A1.

[0100] Step S220: Determine the range of indoor ambient temperature of the air conditioner; and, based on the correspondence between the set indoor ambient temperature range and the set second air outlet temperature threshold, determine the set air outlet temperature threshold corresponding to the set indoor ambient temperature range that is the same as the range of indoor ambient temperature of the air conditioner in the correspondence as the second air outlet temperature threshold corresponding to the range of indoor ambient temperature of the air conditioner, and record it as the second air outlet temperature threshold of the air conditioner, such as temperature threshold Bi.

[0101] Step S240: Based on the lowest air outlet temperature of the air conditioner, the second lowest air outlet temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first air outlet temperature threshold of the air conditioner, and the second air outlet temperature threshold of the air conditioner, control the opening and closing of the auxiliary electric heating block, and control whether the auxiliary electric heating block moves.

[0102] Figure 2 This is a schematic flowchart illustrating an embodiment of a control method for an electric heating device used to improve the uniformity of airflow from an air conditioner according to the present invention. Figure 2 As shown, the present invention proposes a control method for an electric heating device for improving the uniformity of airflow from an air conditioner, comprising:

[0103] Step 1: Obtain the two lower air outlet temperatures from all air outlet grilles of the air conditioner, denoted as air outlet temperature T1 and air outlet temperature T2; and obtain the indoor ambient temperature of the air conditioner, then proceed to Step 2.

[0104] In step 1, to obtain the air outlet temperatures T1 and T2 of the air conditioner, a temperature sensor is installed on each air outlet grille of the air conditioner. Due to differences in duct design between different models, the temperature sensors are positioned directly opposite the air outlet to detect the outlet temperature. Within two hours of the user remotely turning on the air conditioner for heating mode, the air conditioner's control system reads the temperature from each sensor every 5 minutes. Assuming there are n temperature sensors, where n is a positive integer, the temperatures from each sensor, from largest to smallest, are Tn, Tn-1, ..., T2, T1, thus obtaining the air outlet temperatures T1 and T2.

[0105] Step 2: Determine the temperature threshold A1 and temperature threshold Bi, where i is a positive integer, and then proceed to step 3.

[0106] In step 2, when determining the temperature threshold A1, specifically: given that the temperatures of each temperature sensor are obtained in descending order as Tn, Tn-1, ..., T2, T1, except for T1 and Tn, the average value of the temperature of each temperature sensor is determined as the temperature threshold A1, that is, temperature threshold A1 = (Tn-1 + Tn-2 + ... + T3 + T2) / (n-2).

[0107] In step 2, determining the temperature threshold Bi specifically involves considering the different temperature differences between the minimum acceptable air outlet temperature and the indoor ambient temperature at different indoor ambient temperatures. The temperature threshold Bi varies depending on the indoor ambient temperature (as shown in the table below). Furthermore, because different groups of people can tolerate different minimum air outlet temperatures, the indoor ambient temperature also varies depending on the user group.

[0108]

[0109] For example: if the indoor ambient temperature is less than 0℃, then Bi is B1; if the indoor ambient temperature is greater than or equal to 0℃ and less than or equal to 5℃, then Bi is B2; if the indoor ambient temperature is greater than 5℃ and less than or equal to 10℃, then Bi is B3; if the indoor ambient temperature is greater than 10℃ and less than or equal to 15℃, then Bi is B4; if the indoor ambient temperature is greater than 15℃ and less than or equal to 20℃, then Bi is B5; if the indoor ambient temperature is greater than 20℃, then Bi is B6.

[0110] In some embodiments, when the auxiliary electric heating block includes a first electric heating block 3 and a second electric heating block 5, step S240 combines the lowest air outlet temperature of the air conditioner, the second lowest air outlet temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first air outlet temperature threshold of the air conditioner, and the second air outlet temperature threshold of the air conditioner to control the opening and closing of the auxiliary electric heating block and whether the auxiliary electric heating block moves, including: a first process of controlling the auxiliary electric heating block.

[0111] The following is combined Figure 9 The diagram shows an embodiment of the first process of controlling the auxiliary electric heating block in the method of the present invention. It further illustrates the specific process of controlling the auxiliary electric heating block in step S240, including steps S310 to S330.

[0112] Step S310: Determine whether the minimum air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold of the air conditioner, and the second lowest air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold of the air conditioner.

[0113] Step S320: If satisfied, control the first electric heating block 3 to turn on and control the first electric heating block 3 to move to the first position on the moving module; simultaneously, control the second electric heating block 5 to turn on and control the second electric heating block 5 to move to the second position on the moving module; wherein, the first position on the moving module is a position on the moving module that is flush with the air outlet grille corresponding to the lowest air outlet temperature of the air conditioner; the second position on the moving module is a position on the moving module that is flush with the air outlet grille corresponding to the second lowest air outlet temperature of the air conditioner.

[0114] In step S330, if the conditions are not met, then if the lowest air outlet temperature of the air conditioner is less than or equal to the first air outlet temperature threshold and the second lowest air outlet temperature is greater than the first air outlet temperature threshold, the first electric heating block 3 is controlled to turn on, and the first electric heating block 3 is controlled to move to the first position on the moving module. Of course, if neither the conditions are met (the lowest air outlet temperature is less than or equal to the first air outlet temperature threshold and the second lowest air outlet temperature is less than or equal to the first air outlet temperature threshold, nor the conditions are met (the lowest air outlet temperature is less than or equal to the first air outlet temperature threshold and the second lowest air outlet temperature is greater than the first air outlet temperature threshold), then the air conditioner is controlled to maintain its current operation, i.e., the first electric heating block 3 is kept off, and the second electric heating block 5 is kept off.

[0115] In some embodiments, after steps S310 to S330, step S240 combines the lowest air outlet temperature of the air conditioner, the second lowest air outlet temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first air outlet temperature threshold of the air conditioner, and the second air outlet temperature threshold of the air conditioner to control the opening and closing of the auxiliary electric heating block and whether the auxiliary electric heating block moves, and also includes a second process of controlling the auxiliary electric heating block.

[0116] The following is combined Figure 10The diagram shows an embodiment of the second process of controlling the auxiliary electric heating block in the method of the present invention. It further illustrates the specific process of controlling the auxiliary electric heating block in step S240, including steps S410 to S430.

[0117] Step S410: After controlling the first electric heating block 3 to turn on and controlling the first electric heating block 3 to move to the first position on the moving module, determine whether the minimum air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the minimum air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0118] Step S420: If the condition is met, then control the first electric heating block 3 to turn off.

[0119] In step S430, if the conditions are not met, the first electric heating block 3 is controlled to continue heating up, and then the process returns to re-determine whether the conditions are met: the minimum air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the minimum air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0120] In some embodiments, after steps S310 to S330, step S240 combines the lowest air outlet temperature of the air conditioner, the second lowest air outlet temperature of the air conditioner, the indoor ambient temperature of the air conditioner, the first air outlet temperature threshold of the air conditioner, and the second air outlet temperature threshold of the air conditioner to control the opening and closing of the auxiliary electric heating block and whether the auxiliary electric heating block moves, and also includes a third process of controlling the auxiliary electric heating block.

[0121] The following is combined Figure 11 The diagram shows an embodiment of the third process of controlling the auxiliary electric heating block in the method of the present invention. It further illustrates the specific process of the third process of controlling the auxiliary electric heating block in step S240, including steps S510 to S530.

[0122] Step S510: After controlling the second electric heating block 5 to turn on and controlling the second electric heating block 5 to move to the second position on the moving module, determine whether the second lowest air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the second lowest air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0123] Step S520: If the condition is met, then control the second electric heating block 5 to turn off.

[0124] In step S530, if the conditions are not met, the second electric heating block 5 is controlled to continue heating up, and then the process returns to re-determine whether the conditions are met: the second lowest air outlet temperature of the air conditioner is greater than or equal to the first air outlet temperature threshold of the air conditioner, and the absolute value of the temperature difference between the indoor ambient temperature of the air conditioner and the second lowest air outlet temperature of the air conditioner is less than or equal to the second air outlet temperature threshold of the air conditioner.

[0125] Specifically, such as Figure 2 As shown, the present invention proposes a control method for an electric heating device for improving the uniformity of airflow from an air conditioner, which further includes:

[0126] Step 3: Determine whether the conditions of outlet air temperature T1 ≤ temperature threshold A1 and outlet air temperature T2 ≤ temperature threshold A1 are met. If yes, proceed to step 4; otherwise, proceed to step 5.

[0127] Step 4: If the detected air outlet temperature T1 ≤ temperature threshold A1 and the detected air outlet temperature T2 ≤ temperature threshold A1, then the first electric heating block and the second electric heating block are turned on. The first electric heating block 3 moves to the spatial height corresponding to the temperature sensor that detected the air outlet temperature T1, and the second electric heating block 5 moves to the spatial height corresponding to the temperature sensor that detected the air outlet temperature T2. Then, step 41 is executed.

[0128] For a round, upright cabinet air conditioner, the first electric heating block 3 needs to move up and down to the height of the space corresponding to the temperature sensor for outlet air temperature T1, and the second electric heating block 5 needs to move to the height of the space corresponding to the temperature sensor for detecting outlet air temperature T2. Specifically, controlling the movement of the first electric heating block 3 to the height of the temperature sensor for outlet air temperature T1 and the second electric heating block 5 to the height of the temperature sensor for detecting outlet air temperature T2 can be achieved by using an infrared receiver mounted on a spherical rolling wheel 6. This receiver receives signals from the air conditioner's main board and drives the movement of each auxiliary electric heating block accordingly.

[0129] Step 41: After the auxiliary electric heating block is turned on, the air conditioning control system determines every 2 minutes whether the following conditions are met: outlet air temperature T1 ≥ temperature threshold A1 and |T inner ring - outlet air temperature T1| ≤ temperature threshold Bi, and outlet air temperature T2 ≥ temperature threshold A1 and |T inner ring - outlet air temperature T2| ≤ temperature threshold Bi. If neither condition is met, the corresponding electric heating block continues to heat up; if both conditions are met, the corresponding electric heating block stops heating up; if either condition is met, the electric heating block corresponding to the temperature sensor whose temperature does not meet the requirement continues to heat up, while the electric heating block corresponding to the temperature sensor whose temperature meets the requirement stops heating up.

[0130] Step 5: If the detected air outlet temperature T1 ≤ temperature threshold A1 and the detected air outlet temperature T2 > temperature threshold A1, then the first electric heating block is turned on, the first electric heating block 3 moves to the height of the space corresponding to the temperature sensor that detected the air outlet temperature T1, and then step 51 is executed.

[0131] Step 51: After the first electric heating block is turned on, the air conditioner control system determines every 2 minutes whether the outlet air temperature T1 ≥ temperature threshold A1 and |T inner ring - outlet air temperature T1| ≤ temperature threshold Bi. If not satisfied, the first electric heating block continues to heat up; if satisfied, the first electric heating block stops heating up.

[0132] In the present invention, a slide rail (such as slide rail 4 for auxiliary electric heating blocks) and auxiliary electric heating blocks (such as first electric heating block 3 and second electric heating block 5) are added to the electric heating module of the air conditioner. By detecting the temperature of each air outlet, and based on the temperature of the electric heater, the indoor ambient temperature, the average temperature of each temperature sensor, etc., when judging the air outlet temperature of the air conditioner, only the two lower air outlet temperatures, namely air outlet temperature T1 and air outlet temperature T2, are judged. The other n-2 air outlet temperatures do not need to be judged. The lower temperature air outlet is heated by the auxiliary electric heating block. Combined with the temperature difference that is acceptable to the human body, the uniformity of the overall air outlet temperature of the air conditioner is further ensured.

[0133] The air conditioner adopts the electric heating control method of the present invention. By adding a slide rail (such as the slide rail 4 of the auxiliary electric heating block) and an auxiliary electric heating block (such as the first electric heating block 3 and the second electric heating block 5) to the air conditioner's own electric heating module, the temperature of the air outlet with a lower air temperature (that is, the temperature of the air outlet grille with a lower air temperature) can be increased, reducing the overall air outlet temperature difference of the machine by 5% to 15%, ensuring the uniformity of the air outlet temperature of each air outlet grille, and improving the user's comfort experience.

[0134] Since the processing and functions implemented by the method in this embodiment are basically the same as the aforementioned embodiments, principles and examples of air conditioners, any details not covered in this embodiment can be found in the relevant descriptions in the aforementioned embodiments, and will not be repeated here.

[0135] The technical solution of this embodiment, for air conditioners with electric heating modules (such as round vertical cabinet air conditioners), adds slide rails (such as slide rails 4 for auxiliary electric heating blocks) and auxiliary electric heating blocks (such as first electric heating blocks 3 and second electric heating blocks 5) to the air conditioner's own electric heating module (such as main electric heater 2). According to the air conditioner's outlet air temperature and indoor ambient temperature, the auxiliary electric heating blocks are controlled to move on the slide rails to change the position of the auxiliary electric heating blocks at the air conditioner's outlet to adjust the air conditioner's outlet air temperature. By adjusting the auxiliary electric heating blocks, the uniformity of the outlet air temperature of each air outlet grille is ensured, while reducing the air conditioner's energy consumption.

[0136] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous methods can be freely combined and superimposed.

[0137] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
