[0002] There are two common types of auxiliary electric heaters used in air conditioners: stainless steel tubular heaters and PTC heaters. PTC (positive temperature coefficient) heaters are widely used in air conditioners because PTC material is a typical temperature-sensitive semiconductor resistor. When the temperature exceeds a certain level (the Curie temperature), its resistance increases in a stepwise manner. At this point, the power consumption of the PTC heater decreases significantly. Therefore, PTC heaters are highly safe and reliable, making them widely used in air conditioners.

[0003] However, existing PTC electric heaters have the following problems: the starting current is large, and the power will decay during long-term use, resulting in poor heating effect during the overall heating process; and in the existing PTC electric heater control, when the preset temperature is not reached, the PTC electric heaters will all be turned on, and when the preset temperature is reached, the PTC electric heaters will all be turned off. This is easily affected by geographical, environmental, and human factors, resulting in frequent start and stop of the electric heater, shortening the service life of the PTC electric heater, and causing the heating temperature to fluctuate, resulting in a poor user experience.

[0048] Terminal devices 101, 102, and 103 can be various electronic devices with display screens and support web browsing, including but not limited to smartphones, tablet computers, e-book readers, MP3 players (Moving Picture Experts Group Audio Layer III), MP4 (Moving Picture Experts Group Audio Layer IV), laptop computers, desktop computers, etc.

[0049] The server 105 may be a server that provides various services, such as a background server that provides support for web pages displayed on the terminal devices 101 , 102 , and 103 .

[0050] It should be noted that the segmented electric heater control method provided in the embodiment of the present application is generally executed by a server / terminal device, and accordingly, the segmented electric heater control device is generally set in the server / terminal device.

[0051] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is merely illustrative. Any number of terminal devices, networks and servers may be provided as required.

[0052] Continue to refer Figure 2 , shows a flow chart of an embodiment of a method for controlling a segmented electric heater according to the present application. The segmented electric heater control method comprises the following steps:

[0053] Step S201 : obtaining a current pipe temperature value and a heating segment set, wherein the heating segment set includes a plurality of heating segment combinations.

[0054] In this embodiment, the electronic device (eg Figure 1 The server / terminal device shown in FIG. 1 can obtain the current pipe temperature value and the set of heating segments through a wired connection or a wireless connection. It should be noted that the wireless connection method may include, but is not limited to, 3G / 4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future.

[0055] The above-mentioned current tube temperature value is the current tube temperature of the evaporator, which can be directly measured by a temperature sensor.

[0056] The above-mentioned heating segment set includes multiple heating segment combinations; in this solution, the electric heater is designed in a segmented manner, including multiple heating segments, and the heating segments can be arranged and combined according to actual needs to form a heating segment combination, and then the heating segment combinations are merged to form a heating segment set;

[0057] For example, if the power of each heating section is the same: the power required by the electric heater design is 1 kW, 2 kW, and 3 kW. If there are three heating sections (represented by heating section A, heating section B, and heating section C respectively), and the power of each heating section is 1 kW, then there is a first heating section combination with a corresponding power of 1 kW formed by heating section A, a second heating section combination with a corresponding power of 1 kW formed by heating section B, a third heating section combination with a corresponding power of 1 kW formed by heating section C, a fourth heating section combination with a corresponding power of 2 kW formed by heating section A and heating section B, a fifth heating section combination with a corresponding power of 2 kW formed by heating section A and heating section C, a sixth heating section combination with a corresponding power of 2 kW formed by heating section B and heating section C, and a seventh heating section combination with a corresponding power of 3 kW formed by heating section A, heating section B, and heating section C. The first to seventh heating section combinations are combined to form a heating section set.

[0058] For another example, the power of each heating section is different: the power required for the electric heater design is 0.5KW, 1KW, 1.5KW, 2KW, and 2.5KW. If there are three heating sections (the three heating sections are represented by heating section A, heating section B, and heating section C), where the power of heating section A is 0.5KW, the power of heating section B is 1W, and the power of heating section C is 1.5KW, then there is a first heating section combination with a corresponding power of 0.5KW formed by heating section A, and a second heating section combination with a corresponding power of 1.5KW formed by heating section B. The second heating segment combination with a corresponding power of 1KW is formed by the heating segment A and the heating segment B, the third heating segment combination with a corresponding power of 1.5KW is formed by the heating segment C, the fourth heating segment combination with a corresponding power of 1.5KW is formed by the heating segment A and the heating segment C, the fifth heating segment combination with a corresponding power of 2KW is formed by the heating segment A and the heating segment C, and the sixth heating segment combination with a corresponding power of 2.5KW is formed by the heating segment B and the heating segment C. The above-mentioned first to sixth heating segment combinations are merged to form a heating segment set.

[0059] It should be noted that, in the present application, the heating segment combination includes at least one heating segment. When the heating segment combination includes multiple heating segments, the power of each heating segment in the heating segment combination may be the same or different.

[0060] Step S202 : determining a heating condition according to the current pipe temperature value, and matching all the heating segment combinations that meet the heating condition from the heating segment set.

[0061] In this embodiment, initially, the mapping relationship between the current pipe temperature value and the required heating conditions (such as power, voltage and other electrical parameters) can be determined through preliminary experiments; in actual applications, the heating conditions corresponding to the current pipe temperature value can be determined based on the mapping relationship.

[0062] Taking power as an example of the heating condition, after determining the power of the heating condition, a heating segment combination that has a mapping relationship with the power of the enabled target is selected from the heating segment set according to the power of the enabled target; in addition, the heating condition can also be current or voltage, and the current, voltage, and power can be converted according to Ohm's law.

[0063] Continuing with the example of power as the heating condition, and combining with the specific description of the above step S201, after obtaining the power of the heating condition, the power of the heating condition is matched with each heating segment combination in the heating segment set to determine the heating segment combination with the same power as the heating condition.

[0064] It should be noted that the power of the heating section combination is set according to the power of the heating conditions. For example, if the power of the actual required heating conditions is 1KW, 2W, or 3KW, then each heating section combination is designed accordingly according to 1KW, 2W, or 3KW. For details, please refer to the above step S201.

[0065] Step S203: obtaining a rotation mode, and rotatingly starting all the heating section combinations that meet the heating conditions according to the rotation mode.

[0066] In this embodiment, the rotation method includes the start-up sequence and rotation cycle of the heating segment combinations, wherein the start-up sequence is characterized by the sequential start-up sequence of the heating segment combinations that meet the heating conditions. For example, the sequential start-up sequence may be to start the heating segment combination containing fewer heating segments first to reduce the load pressure when the electric heater is initially started; the above-mentioned rotation cycle is characterized by the start-up duration of the heating segment combination. If the start-up duration of the current heating segment combination is reached, the heating segment combination next to the current heating segment combination is rotated and started until all heating segment combinations that meet the heating conditions are rotated.

[0067] In the present application, after determining the heating conditions according to the current pipe temperature value, all heating segment combinations that meet the heating conditions are matched from the heating segment set to achieve precise control of the start and stop of the required heating segment combinations, so that the usage frequency of each heating segment combination is equivalent, the heating segment combinations are reasonably allocated, the utilization rate and the service life of the heating segment combinations are improved, and the problem of excessive temperature changes and sudden changes in temperature caused by frequent start and stop of electric heaters in the prior art is solved, the user experience is improved, and the segmented starting method of the heating segment combination also reduces the starting current to achieve the purpose of energy saving; then, all heating segment combinations that meet the heating conditions are started in rotation to avoid long-term startup of a single heating segment combination, further extending the service life of each heating segment combination, and further improving the rationality of the allocation of heating segment combinations.

[0068] In some optional implementations, in step S202, the step of determining the heating condition according to the current pipe temperature value includes:

[0069] Acquire a preset pipe temperature condition corresponding to the current pipe temperature value from a preset pipe temperature set, wherein the preset pipe temperature set includes a plurality of preset pipe temperature conditions, and the preset pipe temperature condition is a preset pipe temperature threshold or a preset pipe temperature range;

[0070] The preset electrical parameters are determined according to the preset pipe temperature conditions, and the preset electrical parameters are used as heating conditions.

[0071] In this embodiment, the current pipe temperature value is a temperature value, which can be obtained by detecting the evaporator temperature by a temperature sensor; the above-mentioned preset pipe temperature condition can be a preset pipe temperature threshold or a preset pipe temperature range, wherein the preset pipe temperature threshold is a fixed value, such as each preset pipe temperature threshold is T1, T2, T3, etc., and the current pipe temperature value is compared with each preset pipe temperature threshold one by one to determine the preset pipe temperature threshold corresponding to the current pipe temperature value (for example, the current pipe temperature value is 20 degrees, and the corresponding preset pipe temperature threshold is determined to be 20 degrees); the above-mentioned preset pipe temperature range The range is a value such as (T1, T2), [T1, T2), (T1, T2], [T1, T2], etc. After obtaining the current pipe temperature value, determine whether the current pipe temperature value is within the preset pipe temperature range. For example, the preset pipe temperature ranges are (20, 30], (30, 40], etc. If the current pipe temperature value is 30 degrees, it is determined that the current pipe temperature value is within the preset pipe temperature range of (20, 30]. If the current pipe temperature value is 35 degrees, it is determined that the current pipe temperature value is within (30, 40].

[0072] After determining the preset pipe temperature conditions, the preset electrical parameters corresponding to the preset pipe temperature conditions corresponding to the current pipe temperature value are determined based on the mapping relationship between the preset pipe temperature conditions and the preset electrical parameters, where the preset electrical parameters are voltage values, current values, power values, etc.

[0073] It should be noted that the mapping relationship between the preset pipe temperature conditions and the preset electrical parameters can be obtained based on preliminary experiments.

[0074] In some optional implementations, the heating segment combination includes at least one heating segment; and before the step of obtaining the rotation mode, the step further includes:

[0075] Obtaining the operating parameters of each heating segment in all the heating segment combinations that meet the heating conditions;

[0076] Determining a rotation period of each heating segment combination that meets the heating conditions according to the operating parameters of all the heating segments;

[0077] According to all the rotation cycles, a rotation mode of all the heating section combinations that meet the heating conditions is determined.

[0078] In this embodiment, the above-mentioned working parameters may be working time and / or working times; in actual application, every time the heating section starts working and stops working, the time taken from starting working to stopping working is counted to obtain the working time. For example, if the time taken from starting working to stopping working of the heating section is 30 minutes, the obtained working time is 30 minutes; and / or, every time the heating section starts working and stops working, it is recorded as the number of times the heating section works once. For example, the number of times the current heating section works is 0, if the current heating section completes starting and stopping, the number of times the working becomes 1.

[0079] After determining the operating parameters, compare the operating parameters of all heating section combinations. If the operating parameters of heating section combination A are greater than those of heating section combination B, it indicates that heating section combination A has a longer operating time and / or a longer number of operating times. In this heating section startup, the rotation cycle of heating section combination B can be made longer than the rotation cycle of heating section combination A.

[0080] For example, if the working parameter is the working time: if the working time of heating section combination A is greater than the working time of heating section combination B, then during the startup of this heating section, the working time of heating section combination A will be used as a benchmark to adjust the working time of heating section combination B so that the working time of heating section combination B is equal to or almost equal to the working time of heating section combination A. For example, if the working time of heating section combination A is 5 hours and the working time of heating section combination B is 2 hours, during the startup of this heating section, heating section combination B will be started and worked for 3 hours first (this startup working time can be set by yourself or preset at the factory) so that the time of heating section combination B and heating section combination A is equal. If the electric heater still needs to be in the heating state in the subsequent process, heating section combination B can continue to run for the preset time (for example, the preset time is set to 2 hours, the preset time can be adjusted manually according to actual conditions, or it has been pre-set at the factory), and then heating section combination A will run for the preset time.

[0081] It should be noted that the rotation cycle can be determined based on the working parameters of the heating section and the preset duration mentioned above; continuing to take the above working parameters as the working duration as an example, when there is a preset duration, the preset duration is 2 hours. If the working duration difference between the B heating section combination and the A heating section combination is 4 hours, the B heating section combination can be rotated for 4 hours, that is, the rotation cycle is 4 hours at this time. When the rotation cycle of the B heating section combination arrives, the B heating section combination stops, and the A heating section combination starts to heat in a rotation cycle of a preset time of 2 hours.

[0082] Similarly, the principles of working parameters and working hours are the same and will not be elaborated here.

[0083] In some optional implementations, the step of determining, based on the operating parameters of all the heating segments, a rotation period of each heating segment combination that meets the heating condition includes:

[0084] Calculating the sum of the operating parameters of all the heating segments in each of the heating segment combinations that meet the heating conditions to obtain a sum value;

[0085] Comparing the sum values of all the heating section combinations that meet the heating conditions to obtain a comparison result;

[0086] The rotation period of each heating section combination that meets the heating conditions is determined according to the comparison result.

[0087] In this embodiment, the heating segment combination includes at least one heating segment; when the heating segment combination includes one heating segment, the above sum value is the working parameter of the heating segment; when the heating segment combination includes multiple heating segments, the above sum value is the sum of the working parameters of each heating segment.

[0088] After the sum value is calculated, the sum values of each heating section combination are compared to obtain the comparison result of the size relationship between each sum value. Then, the sum values are sorted according to the preset sorting rules (see below for details) and the size relationship between each sum value. For example, after sorting, the sum value of heating section combination A is the smallest, followed by heating section combination B, heating section combination C, etc., then it can be determined that the rotation cycle of heating section combination A is the largest (see the above description), followed by heating section combination B, heating section combination C, so that the precise control of the electric heater is further achieved.

[0089] In some optional implementations, the step of determining, based on all the rotation cycles, the rotation modes of all the heating section combinations that meet the heating conditions includes:

[0090] A preset sorting rule is obtained, and all the rotation cycles are sorted according to the preset sorting rule to obtain a rotation method for all the heating section combinations that meet the heating conditions.

[0091] In this embodiment, the preset sorting rule is sorting from high to low or from low to high, so as to facilitate the determination of the rotation order of each heating section combination and improve the convenience of determining the rotation method.

[0092] In addition, after the rotation method is determined, the rotation method can be stored for subsequent retrieval and viewing, and the sorting method of the rotation method improves the convenience of verification and inspection for operators.

[0093] In some optional implementations, in step S203, the step of rotating and starting all the heating section combinations that meet the heating conditions in the rotation manner includes:

[0094] Determining whether the rotation cycle of the current heating section combination meets the maximum operating time;

[0095] If the rotation cycle of the current heating segment combination meets the maximum operating time, when the rotation cycle of the current heating segment combination is reached, the heating segment combination next to the current heating segment combination is rotated according to the rotation method.

[0096] In this embodiment, the maximum operating time is characterized by the maximum operating time of the heating section combination, so as to protect the heating section combination and prevent the heating section combination from running too long and affecting its service life; when the duration of the rotation cycle reaches the maximum operating time, the start-up of the heating section combination is stopped; if the above working parameters are used as the working time as an example, if the working time difference between the B heating section combination and the A heating section combination is 6 hours, and the maximum operating time is 4 hours, then the rotation cycle of the B heating section combination is determined to be 4 hours, and after the B heating section combination reaches the rotation cycle, the heating section combination is stopped. Stop starting the B heating section combination, and start the A heating section combination to run for 2 hours. When the rotation cycle of the A heating section combination is reached, restart the B heating section combination to run with a rotation cycle of 4 hours. In this way, the B heating section combination and the A heating section combination are eventually made equal or almost equal. After the B heating section combination and the A heating section combination are equal or almost equal, the subsequent starts of the A heating section combination and the B heating section combination are run with a rotation cycle of 2 hours. This can avoid the single heating section combination from running too long and extend the service life of each heating section combination.

[0097] If the rotation cycle of the current heating segment combination does not meet the maximum operating time, the sum value of the current heating segment combination is compared with the sum value of the next heating segment combination. If the sum value of the current heating segment combination is equal to or almost equal to the sum value of the next heating segment combination (the difference between the two sum values is less than the preset value (such as 0.5 hours)), the current heating segment combination is rotated to the next heating segment combination according to the rotation method; if the sum value of the current heating segment combination is not equal to the sum value of the next heating segment combination, the current heating segment combination continues to be rotated.
