[0002] To speed up the drying process, clothes drying equipment, such as dryers, is typically used. However, existing clothes drying equipment dries clothes slowly in low ambient temperatures. To further improve drying speed, a high-powered electric auxiliary heater is usually added. While this method can accelerate the drying process to some extent, the high-powered auxiliary heater needs to be frequently turned on and off, leading to unstable operation of the clothes drying equipment.

[0008] In the preferred embodiment of the above-mentioned electric auxiliary heating control method, the temperature sensor includes at least one of an exhaust temperature sensor, a condenser outlet temperature sensor, an inlet temperature sensor, and an outlet temperature sensor, wherein one of the temperature sensors is a target sensor. The electric auxiliary heating control method further includes: monitoring a first real-time detected temperature of the target sensor; if the first real-time detected temperature is greater than or equal to a set temperature threshold, then shutting off at least part of the target electric auxiliary heating to maintain a balance between heat dissipation supply and demand.

[0009] In the preferred embodiment of the above-mentioned electric auxiliary heating control method, the temperature sensor further includes an electric auxiliary heating protection temperature sensor; the electric auxiliary heating control method further includes: periodically acquiring the second real-time detected temperature of the electric auxiliary heating protection temperature sensor; if the second real-time detected temperature is greater than or equal to the electric auxiliary heating protection temperature threshold, then shutting down the electric auxiliary heating with the lowest power among the target electric auxiliary heatings; if the second real-time detected temperature is greater than or equal to the electric auxiliary heating disconnection temperature threshold, then shutting down the target electric auxiliary heating; if the second real-time detected temperature is less than the electric auxiliary heating recovery threshold, then turning on the electric auxiliary heating that was most recently shut down among the target electric auxiliary heatings.

[0010] In the preferred embodiment of the above-mentioned electric auxiliary heating control method, at least one of the following is included: an electric auxiliary heating protection temperature sensor, an exhaust temperature sensor, an ambient temperature sensor, and a tank inlet temperature sensor; obtaining the current ambient temperature based on the temperature value detected by the temperature sensor includes: if the temperature sensor includes an ambient temperature sensor, determining the temperature value detected by the ambient temperature sensor as the current ambient temperature; if the temperature sensor does not include an ambient temperature sensor, obtaining the temperature values ​​detected by each temperature sensor, and determining the minimum temperature value among the temperature values ​​detected by each temperature sensor as the current ambient temperature.

[0011] Secondly, this application provides an electric auxiliary heating control device applied to a clothes drying equipment equipped with a temperature sensor and multi-stage electric auxiliary heating. The power of each stage of the multi-stage electric auxiliary heating is determined based on the increase in heat dissipation from the lowest temperature point to the highest temperature point within a set ambient temperature range. The electric auxiliary heating control device includes: an acquisition module for acquiring the current ambient temperature based on the temperature value detected by the temperature sensor; a determination module for determining the on / off state of the electric auxiliary heating in the multi-stage electric auxiliary heating based on the target ambient temperature range in which the current ambient temperature is located, so as to meet the heat dissipation requirements under the target ambient temperature range, wherein the on / off state includes an on state and a off state; and a control module for controlling the on / off state of the corresponding electric auxiliary heating.

[0014] Fifthly, this application provides a computer program product, including a computer program that, when executed by a processor, implements the electric auxiliary heating control method as described in the first aspect.

[0015] The electric auxiliary heating control method, device, clothes drying equipment, and storage medium provided in this application are applied to clothes drying equipment equipped with temperature sensors and multi-stage electric auxiliary heating.

The electric auxiliary heating control method includes: obtaining the current ambient temperature based on the temperature value detected by the temperature sensor; determining the on / off state of the electric auxiliary heating in the multi-stage electric auxiliary heating according to the target ambient temperature range in which the current ambient temperature is located, so as to meet the heat dissipation requirements under the target ambient temperature range, wherein the on / off state includes an on state and a off state; and controlling the on / off state of the corresponding electric auxiliary heating. Since the power of each stage of the multi-stage electric auxiliary heating is determined based on the increase in heat dissipation between the lowest and highest temperatures within the set ambient temperature range of the clothes drying equipment, by setting multi-stage electric auxiliary heating with different power levels, it is possible to activate electric auxiliary heating with different power levels or combinations of electric auxiliary heating according to different ambient temperatures. Therefore, in low-temperature environments, the clothes drying equipment can be quickly heated to reach and maintain its optimal operating state. This not only dries clothes but also avoids the problem of unstable operation caused by using only a high-power electric auxiliary heating. Thus, the goal of ensuring normal and stable operation of the clothes drying equipment while increasing drying speed is achieved. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The solutions for improving the drying speed of clothes drying equipment mentioned in the background technology have at least the following technical problems:

[0026] In existing technologies, to address the problem of slow drying speed in clothes drying equipment at low ambient temperatures, a high-power electric auxiliary heater is typically added to the clothes drying equipment to accelerate the drying process. However, due to the high power of the electric auxiliary heater, the temperature it raises quickly reaches the protection temperature of the auxiliary heater, requiring frequent on / off switching. Consequently, the clothes drying equipment cannot operate continuously and stably. Furthermore, the high power of the electric auxiliary heater places a significant impact on the heat pump system of the clothes drying equipment, potentially leading to abnormal operation of the heat pump system.

[0027] To address the aforementioned issues, this application proposes an electric auxiliary heating control method. The core idea is to provide multiple levels of electric auxiliary heating with varying power. This allows for matching different power levels of electric auxiliary heating based on varying ambient temperatures and their power requirements. This enables the heat pump system of the clothes drying equipment to rapidly heat up in low-temperature environments, achieving the goal of quickly drying clothes. Furthermore, once the system temperature of the clothes drying equipment reaches the target temperature, excess electric auxiliary heating can be shut off, ensuring the normal and stable operation of the clothes drying equipment.

[0028] The following is a brief explanation of the terms used in this application.

[0029] Electric auxiliary heating: A device that uses additional electric heating to increase the heating capacity.

[0030] In one possible implementation, the electric auxiliary heating control method provided in this embodiment can be applied in an application scenario. Figure 1 This is a schematic diagram illustrating an application scenario of the electric auxiliary heating control method provided in the embodiments of this application, such as... Figure 1 As shown, this electric auxiliary heating control method can be applied to clothes drying equipment. Taking a heat pump dryer as an example, and a three-stage electric auxiliary heating system as an example, this heat pump dryer can be equipped with an ambient temperature sensor, a drum inlet temperature sensor, a first-stage electric auxiliary heating system, a second-stage electric auxiliary heating system, and a third-stage electric auxiliary heating system. It also includes a controller and a drum. The first-stage, second-stage, and third-stage electric auxiliary heating systems are installed on the rear panel at the drum inlet location. The drum inlet temperature sensor is located behind the condenser on the heat pump system base of the heat pump dryer, and the ambient temperature sensor is installed on the outside of the entire machine. Figure 1 The arrow in the image can be used to indicate the direction of air circulation inside a heat pump dryer.

[0031] In the above scenario, the power of the primary, secondary, and tertiary auxiliary electric heating can be determined based on the increase in heat dissipation of the heat pump dryer at the lowest point relative to the highest point within the corresponding ambient temperature range. The ambient temperature range can be determined by multiple pre-set ambient temperature points; for example, these multiple ambient temperature points may include a high temperature point T. H , room temperature point T M Low and high temperature points T LH Low and medium temperature point T LM and low temperature point T LL And T H >T M >T LH >T LM >T LL Then the power of the primary electric auxiliary heating can be determined by T. LH relative to T M The increased heat dissipation is determined, and the power of the secondary electric auxiliary heating can be determined by T. LM relative to T LH The increased heat dissipation is determined, and the power of the three-stage electric auxiliary heating is determined by T. LL relative to T LH The increase in heat dissipation under ambient temperature is determined.

[0032] In the above scenario, after the ambient temperature sensor detects a temperature, the controller can obtain the temperature value T detected by the ambient temperature sensor, determine this temperature value T as the current ambient temperature, and then determine the ambient temperature range in which the current ambient temperature falls. If T ≥ T HWhen T is active, the controller will not activate any auxiliary electric heating; if T is active... M ≤T<T H Then the controller activates the first-stage electric auxiliary heating; if T LH ≤T<T M Then the controller activates the primary and secondary electric auxiliary heating systems; if T LM ≤T<T LH Then the controller activates the primary, secondary, and tertiary auxiliary electric heaters; if T LL ≤T<T LM The controller then activates the primary, secondary, and tertiary auxiliary electric heaters; if T < T LL The controller then activates the primary, secondary, and tertiary auxiliary electric heaters. Therefore, it enables the heat pump system of the heat pump dryer to rapidly heat up and quickly dry clothes in low-temperature environments.

[0033] In the above scenario, the controller can also detect the temperature value of the inlet temperature sensor. When the temperature value detected by the inlet temperature sensor reaches the set value, it determines that the heat pump system of the heat pump dryer has entered the optimal operating state. Then, it controls the electric auxiliary heating, which is only used for rapid heating, to be turned off, while keeping only the electric auxiliary heating, which keeps the heat pump dryer in the optimal operating state, on. Therefore, the normal and stable operation of the heat pump dryer can be guaranteed.

[0034] In light of the above scenarios, the technical solution of the electric auxiliary heating control method provided in this application will be described in detail below through several specific embodiments.

[0035] Figure 2 A flowchart of the electric auxiliary heating control method provided in the embodiments of this application is shown below. Figure 2 As shown, this electric auxiliary heating control method can be applied to clothes drying equipment equipped with temperature sensors and multi-stage electric auxiliary heating. The electric auxiliary heating control method includes the following steps:

[0036] S201: Obtain the current ambient temperature based on the temperature value detected by the temperature sensor.

[0037] In this step, the clothes drying equipment can be a heat pump dryer. The heat pump dryer can be equipped with a controller. When the heat pump dryer is started, the controller can obtain the temperature values ​​detected by all the temperature sensors set in the heat pump dryer, and then determine the current ambient temperature based on the temperature values ​​detected by all the temperature sensors.

[0038] S202: Determine the on / off state of the electric auxiliary heating in the multi-stage electric auxiliary heating according to the target ambient temperature range where the current ambient temperature is located, so as to meet the heat dissipation requirements under the target ambient temperature range.

[0039] In this step, the switch state can include an on state and an off state. The power of each stage of the multi-stage electric auxiliary heating can be determined after the heat pump dryer reaches and maintains its optimal operating state, based on the increase in heat dissipation between the lowest and highest temperatures within a set ambient temperature range. The target ambient temperature range can be one of multiple ambient temperature ranges, which can be determined based on multiple pre-set ambient temperature points. In practical applications, the multiple ambient temperature points can be determined based on the number of electric auxiliary heating stages and the required precision of the electric auxiliary heating control. For example, when the number of electric auxiliary heating stages is three, the multiple ambient temperature points can include the high-temperature point T. H , room temperature point T M Low and high temperature points T LH Low and medium temperature point T LM and low temperature point T LL Five temperature points, and T H >T M >T LH >T LM >T LL Multiple ambient temperature ranges can include [T H (+∞), [T) M T H ), [T LH ,T M ), [T LM ,T LH ), (T LL ,T LM ), (-∞,T LL Correspondingly, the power of the primary electric auxiliary heating can enable the heat pump dryer to operate at T... LH After reaching optimal operating conditions at ambient temperature, T LH relative to T M The increased heat dissipation is determined, and the power of the secondary electric auxiliary heating can enable the heat pump dryer to operate at T... LM After reaching optimal operating conditions at ambient temperature, T LM relative to T LH The increased heat dissipation is determined, and the power of the three-stage electric auxiliary heating can enable the heat pump dryer to operate at T... LL After reaching optimal operating conditions at ambient temperature, T LL relative to T LH The increase in heat dissipation under ambient temperature is determined, and the power of the first-stage electric auxiliary heating is less than that of the second-stage electric auxiliary heating, which in turn is less than that of the third-stage electric auxiliary heating.

[0040] In the above scheme, by determining whether the electric auxiliary heating needs to be turned on based on the target ambient temperature range where the current ambient temperature is when the heat pump dryer is turned on, it can be determined whether the electric auxiliary heating needs to be turned on. If the electric auxiliary heating needs to be turned on, then in order to meet the heat dissipation requirements of the heat pump dryer to reach the optimal operating state and stabilize in the target ambient temperature range, it is necessary to determine which electric auxiliary heating devices need to be turned on.

[0041] S203: Controls the opening or closing of the corresponding electric auxiliary heating according to the switch status.

[0042] In this step, the on / off status of the electric auxiliary heating in the multi-stage electric auxiliary heating is determined. The corresponding electric auxiliary heating can be turned on or off according to the on / off status, so that the heat pump system of the clothes drying equipment can be heated up quickly to the optimal operating state in low-temperature environments, thereby achieving the purpose of quickly drying clothes and ensuring that the clothes drying equipment can operate normally and stably.

[0043] The electric auxiliary heating control method provided in this application embodiment determines the power of each stage of the multi-stage electric auxiliary heating based on the increase in heat dissipation between the lowest and highest temperatures within a set ambient temperature range. By setting multi-stage electric auxiliary heating with different power levels, different power electric auxiliary heating or combinations of electric auxiliary heating can be activated according to different ambient temperatures. Therefore, in low-temperature environments, the clothes drying equipment can be rapidly heated to reach and maintain its optimal operating state, thus drying clothes while avoiding the problem of unstable operation caused by using only a high-power electric auxiliary heating. This achieves the goal of ensuring normal and stable operation of the clothes drying equipment while increasing drying speed.

[0044] The technical solution of the above-mentioned electric auxiliary heating control method will be described in detail below.

[0045] In one possible implementation, the lower the current ambient temperature, the greater the total power of the electric auxiliary heating elements that are in the on state in the multi-stage electric auxiliary heating.

[0046] In this scheme, the lower the current ambient temperature, the more heat is needed to quickly reach the target temperature. Therefore, the more auxiliary electric heaters need to be activated, and the more stages they need to be, meaning the greater the total power of the auxiliary electric heaters in operation. For example, a multi-stage auxiliary electric heater may include a first-stage, second-stage, and third-stage auxiliary electric heater. When the current ambient temperature is lower than the lowest temperature point T among multiple ambient temperature points... LL When rapid heating is required, all three stages of auxiliary electric heating (primary, secondary, and tertiary) must be activated. This is necessary when the current ambient temperature exceeds the highest temperature point T among multiple ambient temperature points. H When that happens, there is no need to turn on the electric auxiliary heater.

[0047] In the above solution, the more electric auxiliary heaters are activated when the temperature is lower, the faster the internal temperature of the clothes drying equipment can be raised in a lower temperature environment, thereby drying the clothes quickly. Furthermore, since there are multiple electric auxiliary heaters with different powers, the electric auxiliary heaters can be activated reasonably according to the current ambient temperature, avoiding the problem of the heat pump system inside the clothes drying equipment failing to operate normally due to relying on only one high-power electric auxiliary heater. Thus, it is possible to ensure the constant operation of the heat pump system while ensuring the drying speed of the clothes.

[0048] In one possible implementation, the on / off state of the electric auxiliary heating in the multi-stage electric auxiliary heating is determined according to the target ambient temperature range in which the current ambient temperature is located. This includes: determining whether to turn on the electric auxiliary heating according to the target ambient temperature range in which the current ambient temperature is located; if the electric auxiliary heating is turned on, then the on / off state of the target electric auxiliary heating in the multi-stage electric auxiliary heating is determined to be in the on / off state, and the on / off state of the electric auxiliary heating that is not the target electric auxiliary heating is determined to be in the off state, wherein the target electric auxiliary heating includes electric auxiliary heating whose power meets the heat dissipation requirements under the target ambient temperature range; if the electric auxiliary heating is not turned on, then the on / off state of the electric auxiliary heating in the multi-stage electric auxiliary heating is determined to be in the off state.

[0049] In this scheme, the target ambient temperature range can be one of multiple ambient temperature ranges, which can be determined by multiple ambient temperature points. Taking the aforementioned multiple ambient temperature points as an example, the multiple ambient temperature ranges can include (T LL ,T LM ), [T LM ,T LH ), [T LH ,T M ), [T M ,T H In addition, the current ambient temperature can be less than or equal to T. LL Or the current ambient temperature is greater than or equal to T H Therefore, the decision to activate the electric auxiliary heating can be made based on the target ambient temperature range where the current ambient temperature falls.

[0050] For example, taking multi-stage electric auxiliary heating, including primary, secondary, and tertiary electric auxiliary heating, as an example, and denoting the current ambient temperature as T, then if T ≥ T H If T is off, the electric auxiliary heating will not be turned on; at this time, the primary, secondary, and tertiary electric auxiliary heating stages will all be in the off state. M ≤T<T H If T is selected, then the auxiliary electric heating is activated, and the target auxiliary electric heating is the primary auxiliary electric heating. In this case, the primary auxiliary electric heating is activated, while the secondary and tertiary auxiliary electric heating are deactivated. LH ≤T<T MIf T LM ≤T<T LH If T is selected, then the auxiliary electric heating is activated, and the target auxiliary electric heating consists of primary, secondary, and tertiary auxiliary electric heating systems. At this time, all three auxiliary electric heating systems are activated. LL ≤T<T LM If T < T LL If the electric auxiliary heating is activated, the target electric auxiliary heating is a first-stage electric auxiliary heating, a second-stage electric auxiliary heating, and a third-stage electric auxiliary heating. At this time, the first-stage electric auxiliary heating, the second-stage electric auxiliary heating, and the third-stage electric auxiliary heating are all in the activated state.

[0051] In the above solution, by setting up multi-stage electric auxiliary heating with different power levels, it is possible to activate electric auxiliary heating with different power levels or combinations of electric auxiliary heating according to different ambient temperatures. The lower the ambient temperature, the higher the power of the electric auxiliary heating and the more stages are activated. This not only enables the clothes drying equipment to heat up quickly in low-temperature environments, thereby drying clothes quickly, but also avoids the problem of the clothes drying equipment not being able to operate stably due to the use of only one high-power electric auxiliary heating. Therefore, the goal of improving the drying speed of the clothes drying equipment while ensuring normal and stable operation is achieved.

[0052] In one possible implementation, the temperature sensor includes at least one of an exhaust temperature sensor, a condenser outlet temperature sensor, an inlet temperature sensor, and an outlet temperature sensor, wherein one of the temperature sensors is a target sensor. The electric auxiliary heating control method further includes: monitoring a first real-time detected temperature of the target sensor; if the first real-time detected temperature is greater than or equal to a set temperature threshold, then shutting off at least part of the target electric auxiliary heating to maintain a balance between heat dissipation supply and demand.

[0053] In the above scheme, multiple temperature sensors can be used to measure the temperature of multiple parts of the heat pump system inside the clothes drying equipment. One temperature sensor can be selected as the target sensor from among these. For the clothes drying equipment to operate normally and stably, the heat dissipation supply and demand of the internal heat pump system need to be balanced. Therefore, after activating the electric auxiliary heating, it is necessary to monitor in real time whether the first real-time detected temperature of the target sensor has reached the set temperature threshold. Furthermore, when the first real-time detected temperature of the target sensor reaches the set temperature threshold, part of the electric auxiliary heating needs to be turned off to avoid excessively high temperatures, which could lead to an imbalance between heat dissipation supply and demand, or even cause the clothes drying equipment to malfunction. This also achieves the goal of saving resources to some extent.

[0054] Let's continue with the example of multi-stage electric auxiliary heating, which includes primary, secondary, and tertiary electric auxiliary heating:

[0055] In T M ≤T<T H At that time, only the first-level electric auxiliary heating was activated. After a period of time, the first real-time detection temperature T detected by the target sensor... S Reaching the set temperature threshold T t At this time, the temperature of the heat pump system inside the clothes drying equipment can be maintained at T. t In other words, the clothes drying equipment has reached its optimal working state, so the first-level electric auxiliary heating can be turned off at this time.

[0056] In T LH ≤T<T M At that time, the primary and secondary electric auxiliary heating were activated. After a period of time, the target sensor detected the first real-time temperature T. S Reaching the set temperature threshold T t When needed, the secondary electric auxiliary heating can be turned off, and only the primary electric auxiliary heating can be used to maintain the temperature of the target sensor inside the clothes drying equipment. This ensures that the clothes drying equipment can continue to operate stably in its optimal working state, while also saving resources to a certain extent.

[0057] In T LM ≤T<T LH At that time, the primary, secondary, and tertiary auxiliary electric heating were activated. After a period of time, the target sensor detected the first real-time temperature T. S Reaching the set temperature threshold T t In order to ensure that the temperature of the target temperature sensor inside the clothes drying equipment can be stabilized, the third-stage electric auxiliary heating can be turned off, and the first-stage and second-stage electric auxiliary heating can be used to maintain the temperature of the target temperature sensor inside the clothes drying equipment. This ensures that the clothes drying equipment operates smoothly in the best condition, and also saves resources to a certain extent.

[0058] In T LL ≤T<T LM At that time, the primary, secondary, and tertiary auxiliary electric heating were activated. After a period of time, the target sensor detected the first real-time temperature T. S Reaching the set temperature threshold T t When necessary, the secondary electric auxiliary heating can be turned off, and the primary and tertiary electric auxiliary heating can be used to maintain the temperature of the target sensor inside the clothes drying equipment. This ensures that the clothes drying equipment operates stably in the best condition, while also saving resources to a certain extent.

[0059] In T < T LL At that time, the primary, secondary, and tertiary auxiliary electric heating were activated. After a period of time, the target sensor detected the first real-time temperature T. S Reaching the set temperature threshold T t When necessary, the secondary auxiliary electric heating can be turned off, and the primary and tertiary auxiliary electric heating can be used to maintain the target sensor temperature inside the clothes dryer; if the target sensor detects the first real-time temperature T... S The set temperature threshold T has not been reached. t Then, the three electric auxiliary heaters will remain on continuously.

[0060] In one possible implementation, the temperature sensor further includes an electric auxiliary heating protection temperature sensor; the electric auxiliary heating control method further includes: periodically acquiring a second real-time detected temperature from the electric auxiliary heating protection temperature sensor; if the second real-time detected temperature is greater than or equal to the electric auxiliary heating protection temperature threshold, then shutting down the electric auxiliary heating with the lowest power among the target electric auxiliary heatings; if the second real-time detected temperature is greater than or equal to the electric auxiliary heating disconnection temperature threshold, then shutting down the target electric auxiliary heating; if the second real-time detected temperature is less than the electric auxiliary heating recovery threshold, then turning on the electric auxiliary heating that was most recently shut down among the target electric auxiliary heatings.

[0061] In this solution, during the drying process of the clothes drying equipment, it is also necessary to monitor the temperature of the electric auxiliary heating element to prevent the equipment from malfunctioning due to excessively high temperatures. Therefore, the temperature sensor may also include an electric auxiliary heating protection temperature sensor, which monitors the temperature of the electric auxiliary heating element in real time.

[0062] In the above scheme, the second real-time detection temperature T of the electric auxiliary heating protection temperature sensor can be obtained in real time and periodically. Heater Then, the second real-time temperature T was detected. Heater For example, the second real-time detected temperature T is acquired and determined every 30 seconds (s). Heater If the second real-time temperature T Heater Greater than or equal to the electric auxiliary heating protection temperature threshold T HP If the current active electric auxiliary heater has the lowest power, then the second real-time temperature T will be acquired and determined again after 30 seconds. Heater If the second real-time temperature T Heater Still greater than or equal to the electric auxiliary heating protection temperature threshold T HP Then, the electric auxiliary heater with the lowest power among the remaining active electric auxiliary heaters will be turned off, until all electric auxiliary heaters are turned off or the second real-time temperature T is detected. Heater Less than the electric auxiliary heating protection temperature threshold T HP Until then. If the second real-time detected temperature THeater If the threshold for restarting the electric auxiliary heating is lowered, the most recently shut-down stage of the target electric auxiliary heating will be restarted.

[0063] In the above scheme, if the second real-time detected temperature T Heater Greater than or equal to the electric auxiliary heating disconnection temperature threshold T HO If the current state is turned off, all electric auxiliary heaters that are currently on will be turned off, thereby avoiding the problem of the clothes drying equipment malfunctioning due to excessive temperature of the electric auxiliary heaters. This achieves the purpose of protecting the electric auxiliary heaters, and thus ensures that the clothes drying equipment can operate normally while increasing the drying speed.

[0064] In one possible implementation, the temperature sensor includes at least one of an electric auxiliary heating protection temperature sensor, an exhaust temperature sensor, an ambient temperature sensor, and a tank inlet temperature sensor; obtaining the current ambient temperature based on the temperature values ​​detected by the temperature sensor includes: if the temperature sensor includes an ambient temperature sensor, determining the temperature value detected by the ambient temperature sensor as the current ambient temperature; if the temperature sensor does not include an ambient temperature sensor, obtaining the temperature values ​​detected by each temperature sensor, and determining the minimum temperature value among the temperature values ​​detected by each temperature sensor as the current ambient temperature.

[0065] In this solution, when the ambient temperature sensor is included among the multiple temperature sensors, the temperature value detected by the ambient temperature sensor can be directly determined as the current ambient temperature when the clothes dryer is turned on. If the ambient temperature sensor is not included among the multiple temperature sensors, multiple temperature values ​​detected by multiple temperature sensors can be acquired simultaneously when the clothes dryer is turned on. Then, the lowest temperature value is selected from the multiple temperature values ​​and used as the current ambient temperature. In this case, the temperature sensor corresponding to the lowest temperature value can be the target sensor. Subsequently, whether the temperature value detected by the target sensor in real time reaches the set temperature threshold can be used to determine whether to turn off the corresponding electric auxiliary heating.

[0066] In the above scheme, selecting the lowest temperature value as the current ambient temperature can accommodate areas with higher temperatures in the heat pump system inside the clothes drying equipment. This makes the control of electric auxiliary heating more reasonable and avoids the problem of selecting a higher temperature value as the current ambient temperature, which would not meet the needs of areas with lower temperatures in the heat pump system inside the clothes drying equipment, making it impossible to select suitable electric auxiliary heating and thus reducing the drying speed. Therefore, the goal of improving the drying speed while ensuring normal operation of the clothes drying equipment is achieved.

[0067] In the above scheme, the multiple temperature sensors may also include a condenser outlet temperature sensor and a tank outlet temperature sensor, and the condenser outlet temperature sensor and the tank outlet temperature sensor can be configured according to the actual situation.

[0068] Based on the above description, the electric auxiliary heating control method provided in this application can also be implemented through the following steps:

[0069] Step 301: After the clothes drying equipment is turned on, the controller acquires the temperature value detected by the temperature sensor.

[0070] Step 302: Determine the current ambient temperature based on the temperature value detected by the temperature sensor.

[0071] Step 303: Determine the ambient temperature range where the current ambient temperature is located, and activate the electric auxiliary heating required for rapid heating according to the ambient temperature range.

[0072] Step 304: Monitor the temperature value of the inlet temperature sensor in real time. When the inlet temperature reaches the set value, turn off part of the electric auxiliary heating and keep only the electric auxiliary heating that maintains the optimal operating state of the clothes drying equipment on.

[0073] In this step, the controller monitors the temperature value of the inlet temperature sensor in real time. When the inlet temperature reaches the set value, it is considered that the heat pump dryer has reached the optimal operating state. At this time, the electric auxiliary heating that is only for rapid heating is turned off, and only the electric auxiliary heating that keeps the heat pump dryer in the optimal operating state by maintaining this ambient temperature range is turned on.

[0074] Step 305: Based on the temperature value of the electric auxiliary heating temperature protection sensor, control the on / off status of the already activated electric auxiliary heating to protect the safe and reliable operation of the clothes drying equipment.

[0075] In this step, the controller monitors the temperature value of the auxiliary heating protection temperature sensor in real time. If the temperature value of the auxiliary heating protection temperature sensor exceeds the auxiliary heating protection temperature threshold for a certain period of time, the auxiliary heating stage with the lowest current power is turned off. After a certain period of time, if the temperature value of the auxiliary heating protection temperature sensor is lower than the auxiliary heating recovery threshold, the most recently turned-off auxiliary heating stage is turned on again. If the temperature value of the auxiliary heating protection temperature sensor still exceeds the auxiliary heating protection temperature threshold after a certain period of time, the auxiliary heating stage with the lowest current power is turned off again, and so on, until all auxiliary heating stages are turned off. After a certain period of time, if the temperature value of the auxiliary heating protection temperature sensor is lower than the auxiliary heating recovery threshold, the most recently turned-off auxiliary heating stage is turned on again.

[0076] In general, the electric auxiliary heating control method provided in this application can activate electric auxiliary heating or combinations of electric auxiliary heating according to the detected current ambient temperature. The lower the ambient temperature, the more electric auxiliary heating is activated. Therefore, it can achieve the goal of rapidly heating the heat pump system inside the clothes drying equipment even at low ambient temperatures. Furthermore, once the target sensor temperature reaches the target temperature, the excess electric auxiliary heating is turned off, and only the electric auxiliary heating that can maintain the stable temperature of the heat pump system is turned on. Therefore, the clothes drying equipment can operate continuously and stably, ultimately achieving the goal of rapidly drying clothes at low ambient temperatures. At the same time, it also achieves the goal of saving resources to a certain extent.

[0086] Optionally, the temperature sensor includes at least one of an electric auxiliary heating protection temperature sensor, an exhaust temperature sensor, an ambient temperature sensor, and a tank inlet temperature sensor.
