[0030] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0031] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0032] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0033] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "below" another element or feature would then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

[0034] With the upgrading of air conditioners, their electric auxiliary heating devices are equipped with more gears to achieve multi-level adjustment and control of the electric auxiliary heating function. However, in some countries and regions, the wired controller used to control the operation of the air conditioner has fewer auxiliary heating adjustment gears than the electric auxiliary heating device. For example, the electric auxiliary heating device has three gears, while the wired controller has only two gears. As a result, the existing wired controller does not provide precise control and adjustment for the electric auxiliary heating device, and cannot fully utilize the auxiliary heating function of the electric auxiliary heating device.

[0035] According to an embodiment of the present disclosure, the air conditioner includes an indoor unit that delivers hot air to the indoor room. The indoor unit is provided with an electric auxiliary heating device and an indoor fan. When the electric auxiliary heating device is in operation, it converts electrical energy into thermal energy, and drives the gas flow through the indoor fan to deliver the heat generated by the electric auxiliary heating device to the indoor room to increase the indoor temperature.

[0036] In particular, based on factors such as climate and building structure, the air conditioner and control device in the air conditioning system are located in different spaces, or the air conditioner and control device are located in different locations within the same space to facilitate user operation. For example, the control device is generally placed in the bedroom for easy user operation, and the air conditioner is placed in an attic or basement, making the air conditioner and control device relatively far apart. An air supply duct is arranged between the air conditioner and the control device to deliver the cold or hot air generated by the air conditioner to the bedroom. The air conditioner and the control device are connected to each other for signal transmission, allowing the user to issue control commands to the air conditioner by operating the control device in a space such as the bedroom to control the operation of the air conditioner. In this embodiment, the control device includes but is not limited to a wired controller, a remote controller, etc.

[0037] The air conditioner and the control device are connected via a wire, or wirelessly by inserting a phone card between the control device and the air conditioner, or wirelessly by Bluetooth, Wi-Fi, or any other wireless communication method. The air conditioner receives control commands from the control device based on the communication with the control device and controls the operation of the electric auxiliary heating device based on the control commands.

[0038] In this embodiment, the control device is provided with N gears, and the electric auxiliary heating device is provided with M gears, where M>N, i.e., the electric auxiliary heating device has more gears than the control device. Therefore, the control instruction issued by the control device alone cannot activate all gears of the electric auxiliary heating device. Therefore, as shown in FIG1 , the present disclosure provides an auxiliary heating adjustment method for an air conditioner, which includes the following steps:

[0039] Step S101: controlling the electric auxiliary heating device to start the Nth gear according to the Nth gear start instruction issued by the control device;

[0040] Step S102: obtaining indoor temperature parameters after the electric auxiliary heating device is turned on to the Nth level;

[0041] Step S103: Calculating a first difference parameter of the target temperature minus the indoor temperature parameter;

[0042] Step S104: controlling the electric auxiliary heating device to start the N+a gear according to the Nth gear start instruction and the first difference parameter satisfying the first preset condition.

[0043] In this embodiment, M, N, and a are all natural numbers, and 1≤a≤M-N.

[0044] In step S101, if the control device's gear is not equal to the electric auxiliary heating device's gear and is smaller than the number of gears in the electric auxiliary heating device, the control device can only issue a control instruction corresponding to its own gear to the air conditioner, preventing the electric auxiliary heating device from properly starting at a gear higher than the control device's. For example, if the control device only has two gears—first and second—and the electric auxiliary heating device has three gears—first, second, and third—then, when the control device issues a first gear start instruction, the electric auxiliary heating device starts at the first gear, and when the control device issues a second gear start instruction, the electric auxiliary heating device starts at the second gear. However, since the control device does not have a third gear, the control instruction issued by the control device alone cannot control the electric auxiliary heating device to start at the third gear. In this step, when the air conditioner receives the Nth gear start instruction from the control device, the electric auxiliary heating device starts heating at the Nth gear according to the received control instruction.

[0045] In some embodiments, when N ≥ 2, the electric auxiliary heating device gradually increases in level as it switches from an off state to the Nth level, operating at each level for a preset time before switching to the next level. For example, when N = 2, the electric auxiliary heating device first switches to the first level, then switches to the second level after the first level remains on for a preset time. This prevents the electric auxiliary heating device from switching to a high level in a short period of time, which could cause a sudden increase in load on the power grid and a significant impact on the power grid. The preset time ranges from 1 to 60 seconds, and can be set to, for example, 1 second, 3 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds, etc.

[0046] In step S102, when the electric auxiliary heating device is turned on to the Nth gear, the indoor fan drives the airflow to transport the heat generated by the electric auxiliary heating device into the room, thereby increasing the indoor temperature. The indoor temperature is obtained and recorded in real time to obtain a data set of indoor temperature parameters showing the indoor temperature changing with time after the electric auxiliary heating device is turned on to the Nth gear. Based on the indoor temperature parameters, the auxiliary heating effect of the electric auxiliary heating device after being turned on to the Nth gear can be intuitively understood.

[0047] In step S103, the target temperature is the temperature that the user expects the indoor temperature to reach. The user sends a control instruction to the air conditioner through the control device to adjust the indoor temperature to the target temperature. In the heating mode, when the indoor temperature is lower than the target temperature, it means that the air conditioner or the electric auxiliary heating device still needs to continue to supply heat to the room, and by calculating a first difference parameter of the target temperature minus the indoor temperature parameter, the current user's heating demand can be determined according to the size of the first difference parameter. When the first difference parameter is greater than zero, the larger the value of the first difference parameter, the lower the indoor temperature, and the greater the heat output of the electric auxiliary heating device.

[0048] In step S104, when the Nth gear of the control device is turned on, it indicates that the current user has a demand and intention for heating. Moreover, when the first difference parameter satisfies the first preset condition, it indicates that the current indoor temperature is too low and that only turning on the Nth gear of the electric auxiliary heating device cannot meet the actual heating demand. Therefore, when both the air conditioner receives the Nth gear turning-on instruction of the control device and the first difference parameter satisfies the first preset condition, the electric auxiliary heating device is controlled to turn on the N+ath gear to further enhance the heating capacity of the electric auxiliary heating device.

[0049] It should be noted that if a ≥ 1, the electric auxiliary heating device will directly increase the gear to gear N+a. When a ≥ 2, the electric auxiliary heating device will increase the gear gradually, and each gear will operate for a preset time before the next gear is activated. For example, when a = 2, the electric auxiliary heating device will first activate gear N+1, and after the N+1 gear is activated for a preset time, it will activate gear N+2. This prevents the electric auxiliary heating device from being directly activated to a high gear in a short period of time, causing a sudden increase in grid load and a significant impact on the grid. The preset time range is 1 second to 60 seconds, and can be set to 1 second, 3 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds, etc.

[0050] The auxiliary heating adjustment method proposed in this embodiment can determine the actual needs of the current user based on the first difference parameter, and automatically adjust the gear of the electric auxiliary heating device according to the actual needs. When the control gear of the control device is less than the control gear of the electric auxiliary heating device, intelligent control of the electric auxiliary heating device is achieved, so that all gears of the electric auxiliary heating device can be turned on, and the full auxiliary heating function of the electric auxiliary heating device is brought into play, thereby improving the user experience and expanding the applicability of the air conditioner.

[0051] In this embodiment, the first difference parameter satisfies the first preset condition including:

[0052] The first difference parameters in the first time period after the electric auxiliary heating device is turned on at gear N are all greater than the first preset value, and the first preset value is greater than zero. When the first difference parameters are greater than the first preset value, it indicates that the indoor temperature is far below the target temperature and cannot meet user needs. In the first time period, if any one of the first difference parameters is greater than the first preset value, it indicates that after the electric auxiliary heating device is turned on at gear N and continues to operate for the first time period, the indoor temperature is still far below the target temperature. Therefore, it can be determined that the heating capacity of the electric auxiliary heating device when it is turned on at gear N is insufficient to meet current needs, and the gear of the electric auxiliary heating device can be increased to gear N+a.

[0053] Alternatively, the first difference parameter within a second time period after the electric auxiliary heating device is turned on at gear N is greater than or equal to the second preset value, and the increment of the indoor temperature parameter is less than or equal to zero. In this embodiment, when the second preset value is less than the first preset value and greater than or equal to the second preset value, after the electric auxiliary heating device is turned on at gear N and continues to operate for the second time period, it indicates that the current indoor temperature is relatively close to the target temperature value, but the current indoor temperature is still lower than the target temperature value. Therefore, it is determined whether the increment of the indoor temperature parameter within the second time period is less than or equal to zero. If so, it indicates that after the electric auxiliary heating device is turned on at gear N and operates for a long time, the heat output of the electric auxiliary heating device to the room has equaled the heat dissipation in the room, causing the indoor temperature to no longer rise. In some cases, the heat output of the electric auxiliary heating device to the room is less than the heat dissipation in the room, causing the indoor temperature to drop. Therefore, the gear of the electric auxiliary heating device is increased to gear N+a, thereby increasing the heat output capacity of the air conditioner and achieving the purpose of raising the indoor temperature.

[0054] It should be noted that, in this embodiment, the first preset value is greater than the second preset value, and the second time period is greater than the first time period. In some embodiments, the value range of the first preset value is 3°C to 6°C, and the value range of the second preset value is 0.5°C to 2°C. For example, the first preset value can be set to 3°C, 4°C, 5°C, or 6°C, and the second preset value can be set to 0.5°C, 1°C, 1.5°C, or 2°C, or the first preset value and the second preset value can be set to other values ​​according to actual needs.

[0055] The value range of the first time period is 1 minute to 10 minutes, and the value range of the second time period is 10 minutes to 30 minutes. For example, the first time period can be set to 1 minute, 2 minutes, 4 minutes, 5 minutes, 8 minutes, 9 minutes, etc., and the second time period can be set to 10 minutes, 15 minutes, 20 minutes, 25 minutes, 28 minutes, 30 minutes, etc.

[0056] In other embodiments, the first time period is equal to the second time period, or the first time period is greater than the second time period.

[0057] As shown in FIG2 , the present disclosure provides an auxiliary heat regulation method for an air conditioner, which includes the following steps:

[0058] Step S201: controlling the electric auxiliary heating device to start the Nth gear according to the Nth gear start instruction issued by the control device;

[0059] Step S202: obtaining indoor temperature parameters after the electric auxiliary heating device is turned on to the Nth level;

[0060] Step S203: Calculating a first difference parameter of the target temperature minus the indoor temperature parameter;

[0061] Step S204: controlling the electric auxiliary heating device to start the N+a gear according to the N gear start instruction and the first difference parameter satisfying the first preset condition;

[0062] Step S205: Calculating a second difference parameter of the target temperature minus the indoor temperature parameter;

[0063] Step S206: controlling the electric auxiliary heating device to start the N+a-1th gear according to the second difference parameter satisfying the second preset condition.

[0064] In this embodiment, steps S201 to S204 are the same as steps S101 to S104 and are not described again herein.

[0065] In step S205, after the electric auxiliary heating device is controlled to increase the gear to the N+a gear, the indoor temperature parameter is obtained in real time, and a second difference parameter is calculated, which is the target temperature minus the indoor temperature parameter. According to the second difference parameter, it can be determined whether the indoor temperature reaches and exceeds the target temperature value after the electric auxiliary heating device is turned on to the N+a gear. It can be understood that when the second difference parameter is greater than or equal to zero, it means that the indoor temperature has reached and exceeded the target temperature value.

[0066] In step S206, when the second difference parameter satisfies the second preset condition, it indicates that the current indoor temperature has reached and exceeded the target temperature value, meeting the user's needs. Therefore, to avoid excessively high indoor temperature and save electricity, the electric auxiliary heating device is controlled to open the N+a-1th gear to reduce the heat output capacity of the electric auxiliary heating device, so that the indoor temperature can be reduced and return to the optimal range, thereby improving user comfort.

[0067] In this embodiment, the second difference parameter satisfies the second preset condition, which includes:

[0068] The second difference parameters in the first time period after the electric auxiliary heating device is turned on at gear N+a are all less than or equal to the third preset value, and the third preset value is less than zero. When the second difference parameter is less than or equal to the third preset value, it indicates that the indoor temperature is much higher than the target temperature and has exceeded the user's demand. In the first time period, if any one of the second difference parameters is less than or equal to the third preset value, it indicates that after the electric auxiliary heating device is turned on at gear N+a and continues to operate for the first time period, the indoor temperature rises to higher than the target temperature. Therefore, it can be determined that the heating capacity of the electric auxiliary heating device when it is turned on at gear N+a has met and exceeded the current demand, and the gear of the electric auxiliary heating device can be reduced to gear N+a-1.

[0069] Alternatively, if the second difference parameter within a second time period after the electric auxiliary heating device is activated at level N+a is greater than the third preset value and less than or equal to the fourth preset value, and the increment of the indoor temperature parameter is greater than or equal to zero, in this embodiment, when the second preset value is greater than the third preset value and less than or equal to the fourth preset value, this indicates that after the electric auxiliary heating device has been activated at level N+a and continued to operate for the second time period, the current indoor temperature is relatively close to the target temperature, but the current indoor temperature is still higher than the target temperature. Therefore, it is determined whether the increment of the indoor temperature parameter within the second time period is greater than or equal to zero. If so, this indicates that after the electric auxiliary heating device has been activated at level N+a and operated for a long time, the heat output of the electric auxiliary heating device to the room has equaled the amount of heat dissipated indoors, causing the indoor temperature to remain higher than the target temperature. In some cases, the heat output of the electric auxiliary heating device to the room may be greater than the amount of heat dissipated indoors, causing the indoor temperature to continue to rise. Therefore, the electric auxiliary heating device is downgraded to level N+a-1, thereby reducing the heat output capacity of the air conditioner and lowering the indoor temperature from above the target temperature to the target temperature, thereby saving energy.

[0070] It should be noted that, in this embodiment, the third preset value and the fourth preset value are both less than zero, and the third preset value is less than the fourth preset value, the second time period is greater than the first time period, and in some embodiments, the value range of the third preset value is -6°C to -3°C, and the value range of the fourth preset value is -2°C to 0.5°C. For example, the third preset value can be set to -3°C, -4°C, -5°C, -6°C, and the fourth preset value can be set to -0.5°C, -1°C, -1.5°C, -2°C, or the third preset value and the fourth preset value can be set to other values ​​according to actual needs.

[0071] In some embodiments, the absolute value of the first preset value is equal to the absolute value of the third preset value, and the absolute value of the second preset value is equal to the absolute value of the fourth preset value.

[0072] The value range of the first time period is 1 minute to 10 minutes, and the value range of the second time period is 10 minutes to 30 minutes. For example, the first time period can be set to 1 minute, 2 minutes, 4 minutes, 5 minutes, 8 minutes, 9 minutes, etc., and the second time period can be set to 10 minutes, 15 minutes, 20 minutes, 25 minutes, 28 minutes, 30 minutes, etc.

[0073] In other embodiments, the first time period is equal to the second time period, or the first time period is greater than the second time period.

[0074] In this embodiment, the step of obtaining the increment of the indoor temperature parameter in the second time period includes:

[0075] Step S301: dividing the second time period into at least two heating time periods;

[0076] Step S302: obtaining the average temperature of the indoor temperature parameter in each heating time period;

[0077] Step S303: calculating, in chronological order, a unit increment value of the temperature average value of the subsequent heating time period minus the temperature average value of the previous heating time period;

[0078] Step S304: Calculate the sum of all unit increment values ​​to obtain the increment of the indoor temperature parameter.

[0079] In this embodiment, the unit increment value refers to the difference between any two adjacent heating time periods, obtained by subtracting the average temperature value in the latter heating time period from the average temperature value in the previous heating time period.

[0080] If the second time period is set to 10 minutes and the second time period is equally divided into two heating time periods, i.e., the time period of the first heating time period is 0 to 5 minutes and the time period of the second heating time period is 5 to 10 minutes, and the temperature average value t1 of the indoor temperature parameter during the first heating time period is calculated, and the temperature average value T2 of the indoor temperature parameter during the second heating time period is calculated, then the increment of the indoor temperature parameter Δt = t2 - t1. If Δt is greater than zero, it means that the indoor temperature increased during the second time period; if Δt is less than zero, it means that the indoor temperature decreased during the second time period; if Δt is equal to zero, it means that the indoor temperature remained unchanged during the second time period.

[0081] It is understandable that the second time period can also be equally divided into three, four or more heating time periods, which are not listed here one by one.

[0082] In some embodiments of the present disclosure, the calculation of the incremental value of the indoor temperature parameter can take the indoor temperature parameter values ​​at the beginning and end of the second time period, for example, obtaining the indoor temperature parameter t1 at the start moment of the second time period and the indoor temperature parameter t2 at the end moment of the second time period, and the increment of the indoor temperature parameter Δt = t2-t1.

[0083] In some embodiments of the present disclosure, as shown in FIG4 , the auxiliary heat regulation method includes the following steps:

[0084] Step S401: controlling the electric auxiliary heating device to start the Nth gear according to the Nth gear start instruction issued by the control device;

[0085] Step S402: obtaining indoor temperature parameters after the electric auxiliary heating device is turned on to the Nth level;

[0086] Step S403: Calculate a first difference parameter of the target temperature minus the indoor temperature parameter;

[0087] Step S404: controlling the electric auxiliary heating device to start the N+a gear according to the N gear start instruction and the first difference parameter satisfying the first preset condition;

[0088] Step S405: controlling the electric auxiliary heating device to gradually reduce the gear to the N-1th gear according to the Nth gear closing instruction issued by the control device.

[0089] In this embodiment, steps S401 to S404 are the same as steps S101 to S104 and are not described again herein.

[0090] In step S405, after the air conditioner receives the Nth gear off instruction from the control device, it controls the electric auxiliary heating device to gradually reduce the gear to the N-1th gear according to the instruction to respond to the user's gear reduction instruction.

[0091] Understandably, if the electric auxiliary heating device is currently in a gear that is more than two gears higher than the N-1 gear, it is necessary to control the electric auxiliary heating device to gradually decrease its gear, running in each gear for a preset time before lowering it to the next gear. For example, when the electric auxiliary heating device is in the N+1 gear, after receiving the N gear off command, the electric auxiliary heating device first lowers to the N gear, then remains in the N gear on state for a preset time, and then lowers to the N-1 gear. This prevents the electric auxiliary heating device from being directly lowered to a lower gear in a short period of time, causing a sudden drop in grid load and a significant impact on the grid. The preset time range is 1 second to 60 seconds, and for example, the preset time can be set to 1 second, 3 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds, etc.

[0092] In some embodiments of the present disclosure, as shown in FIG5 , the auxiliary heat regulation method includes the following steps:

[0093] Step S501: controlling the electric auxiliary heating device to start the Nth gear according to the Nth gear start instruction issued by the control device;

[0094] Step S502: obtaining indoor temperature parameters after the electric auxiliary heating device is turned on to the Nth level;

[0095] Step S503: Calculate a first difference parameter of the target temperature minus the indoor temperature parameter;

[0096] Step S504: controlling the electric auxiliary heating device to start the N+a gear according to the N gear start instruction and the first difference parameter satisfying the first preset condition;

[0097] Step S505: obtaining indoor temperature parameters after the electric auxiliary heating device is turned on at level N+a;

[0098] Step S506: Calculate a first difference parameter of the target temperature minus the indoor temperature parameter;

[0099] Step S507: controlling the electric auxiliary heating device to start the N+a+1th gear according to the first difference parameter satisfying the first preset condition;

[0100] Among them, 1≤a≤MN-1.

[0101] In this embodiment, steps S501 to S504 are the same as steps S101 to S104 and are not described again herein.

[0102] In steps S505 to S507, when the electric auxiliary heating device is turned on to the N+ath level, it is still necessary to obtain the indoor temperature parameter in real time and determine whether the user's actual heating demand can be met after the electric auxiliary heating device is turned on to the N+ath level based on the first difference parameter of the target temperature minus the indoor temperature parameter. If the heating capacity of the electric auxiliary heating device still does not meet the demand, the level of the electric auxiliary heating device is further increased.

[0103] In some embodiments of the present disclosure, the auxiliary heat regulation method further includes the following steps:

[0104] Obtain the wind speed of the indoor fan and determine whether the wind speed of the indoor fan is at the highest wind speed;

[0105] Keep the electric auxiliary heating device turned on when the indoor fan is at the highest wind speed;

[0106] If the indoor fan is not at the highest wind speed, gradually reduce the speed of the electric auxiliary heating device until the electric auxiliary heating device is turned off.

[0107] In this embodiment, if the indoor unit fan is not at the highest wind speed, the electric auxiliary heating device is turned off to prevent the heat generated by the electric auxiliary heating device from not being able to be dissipated in time by the airflow driven by the indoor unit fan, resulting in a burning accident. When the indoor unit fan is at the highest speed, the electric auxiliary heating device can be turned on, and the speed of the electric auxiliary heating device can be increased or decreased according to the indoor temperature parameters and the target temperature in combination with the control instructions issued by the control device.
