Description

Technical Field

[0001] The present invention relates to the technical field of clothes dryers, and in particular to a clothes dryer control method and the clothes dryer. Background Art

[0002] Tumble dryers, or washer-dryers, can be broadly divided into two categories based on their dehumidification method: direct-exhaust and condensing. Condensing types can be further categorized as water-based and heat pump-based. Direct-exhaust dryers are significantly affected by the external environment (temperature and humidity) during the drying process, while water-based condensing dryers are significantly affected by the condensing water temperature. However, when the condensing water temperature fluctuates slightly, the external environment has relatively little impact. Heat pump dryers are less affected by the external environment, but are more expensive.

[0003] The external environment of a direct-exhaust dryer significantly impacts drying results. Common direct-exhaust dryers draw in external air for heating, then exchange heat with the interior of the drum before blowing the hot, moist air out directly. Based on this simple process, high ambient temperatures (high ambient temperatures often indicate high humidity; hot and arid regions may not require a dryer and will not affect this solution) can reduce drying efficiency and affect dryness accuracy.

[0004] Common condensing tumble dryers require at least two temperature sensors to determine whether the clothes are dry. These sensors are placed at both ends of the condensing section and use real-time temperature differences to determine whether the clothes are dry. Direct-exhaust dryers require a temperature and humidity sensor to determine whether the clothes are dry based on real-time changes in temperature and humidity. Direct-exhaust dryers on the market that use a single temperature sensor cannot accurately determine whether the clothes are dry. Summary of the Invention

[0064] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0065] Implementation Case 1:

[0066] like Figure 1 As shown, a control method for a clothes dryer includes the following steps:

[0067] When the dryer starts, the circulating heating is turned off and the fan runs for a time of T on , obtain and record the current temperature as F on , current temperature F on Before entering the dryer without circulating heating, it can be used to represent the ambient temperature of the environment where the dryer is located. The running time T of this embodiment is on 1-5min.

[0068] At the current temperature F on Compared with the second temperature F2, the second temperature F2 is a pre-set fixed temperature value used to define the high-temperature ambient temperature threshold. In this embodiment, the second temperature F2 is set to 40°C or 45°C, which is used to determine whether the current environmental conditions are high-temperature environmental conditions. Generally, an ambient temperature greater than 40°C is defined as a high-temperature environmental condition.

[0069] Determine whether the current environment is a high temperature environment. on When the temperature is less than F2, the circulating heating operation is started, and a temperature sensing package provided in the dryer is used to obtain the real-time temperature F of the dryer during operation. The real-time temperature F is the temperature of the air outlet or the temperature inside the barrel when the external air is blown to the interior after being circulated and heated by the dryer. The circulating heating in this embodiment is that each part including the motor and the fan rotates forward and reverse according to a certain rule and a predetermined speed, and the electric heating works continuously. The continuous operation of the electric heating in this embodiment also includes the intermittent operation of the electric heating of some products according to a certain rule.

[0070] Run cycle heating, when the real-time running time T reaches the running time T max When T≥T maxWhen , it means that the dryer runs a complete drying cycle and then performs the cooling end step. The running time of this embodiment is T max The preset time for a complete drying cycle and the maximum heating run time.

[0071] The cooling end step includes stopping the circulating heating to cool the real-time temperature F to the door opening temperature F off , where the door opening temperature F off It is a pre-set fixed temperature value, which is slightly higher than the temperature F on ; When the real-time temperature F≤F off When , stop the fan and end.

[0072] In order to solve the problems of excessively high temperature drying, inability to accurately judge drying, and low drying efficiency during the operation of the dryer, this embodiment provides further improvements. max Compare the real-time temperature F with the first temperature F1 and the maximum temperature F max , wherein the first temperature F1 and the limited maximum temperature F max The first temperature F1 in this embodiment is a fixed temperature value selected based on energy saving, power consumption and drying efficiency. When the temperature in the barrel reaches this value, it starts to heat in a half-power cycle to maintain the temperature. The maximum temperature Fmax is the highest fixed temperature value set in the dryer barrel. When the temperature in the barrel reaches this value, it needs to be cooled to avoid high temperature damage to the clothes. It is used to provide temperature protection for the dryer. The first temperature F1 < the maximum temperature Fmax max .

[0073] When F<F1, execute the first judgment step;

[0074] When F1≤F≤F max When the heating cycle is half-powered, the first dryness determination step is performed;

[0075] When F>F max When the temperature is less than 0.05, the circulating heating is stopped and the fan is kept running to reduce the real-time temperature F and keep supplying air to the interior until F≤F max .

[0076] The first dry determination step includes determining whether the real-time temperature F is satisfied based on a first dry determination condition, continuing normal cycle heating or half-power cycle heating operation if the first dry determination condition is not satisfied, and executing a cooling end step if the first dry determination condition is satisfied;

[0077] The first judgment condition includes:

[0078] Determine the current temperature difference ΔF ≥ K, where the current temperature difference ΔF = FF on, K is the pre-set value in F on The first threshold value in the ambient temperature range, such as Figure 3 As shown, the K value satisfies the curve shown in the figure. The horizontal axis of the curve in the figure is the ambient temperature, and the vertical axis is the K value corresponding to the ambient temperature range. When the calculated temperature difference ΔF ≥ the temperature F used to calculate the temperature difference on When the K value in the ambient temperature range, that is, the temperature difference ΔF, is above the curve in the figure, it means that the first dryness condition is met, specifically:

[0079] When FF on ≥K, indicating that the clothes have reached a dry state;

[0080] When FF on <K, indicating that the clothes are not dry.

[0081] The first dryness determination condition of this embodiment can also adopt other dryness determination methods in the prior art, which is mainly used to obtain a signal to determine whether the clothes are dry. Other dryness determination methods do not affect the execution steps of this embodiment.

[0082] This implementation case uses a single temperature sensing package to reduce the impact of the dryer's external environment on the drying results, reduce sensors and reduce costs, and can meet the requirements of accurate dryness judgment and overheating protection.

[0083] Implementation Case 2:

[0084] A control method for a clothes dryer, based on the implementation case 1, further includes the following steps:

[0085] After the dryer starts to run the cycle heating, the running time T min Determine whether the real-time temperature F exceeds the maximum temperature F max , where the running time is T min The set minimum operating time value is used to heat the clothes to the specified maximum temperature within the shortest operating time. This can result in a light load in the clothes dryer, that is, only a small amount of clothes or clothes with very low moisture content in the clothes dryer. Specifically:

[0086] If F < F max , then continue normal cycle heating operation;

[0087] If F ≥ F max , then execute the light load drying step;

[0088] The light load drying step comprises:

[0089] Stop the circulating heating to allow the real-time temperature F to start cooling down. The fan operates normally. When the real-time temperature F drops to the first temperature F1, the circulating heating starts at half power and continues for the heating time T. m , the running time Tm This is a pre-set fixed time value for light-load drying with little clothes or little water. Considering that it can be heated to the limited maximum temperature in the shortest time and the load in the dryer is small, setting a fixed time value to run can ensure that the light load can be dried.

[0090] When T ≥ T m , execute the cooling end step.

[0091] This embodiment is designed to handle clothing with very little or very low moisture content, ensuring that it will not be damaged by high temperatures and that the clothing is dry after being taken out.

[0092] Implementation Case 3:

[0093] A control method for a clothes dryer, including a high-temperature drying step. Specific parameter settings refer to Example 1, which will not be repeated in this example.

[0094] When the dryer starts, the circulating heating is turned off and the fan runs for a time of T on , obtain and record the current temperature as F on , with the current temperature F on Compare with the second temperature F2 to determine whether the current environmental condition is a high temperature environmental condition. on When ≥F2, it means the dryer is in a high temperature environment. Perform the following steps:

[0095] Start circulating heating and run for T max In the embodiment, the real-time temperature F is monitored to see whether it satisfies the second dry condition:

[0096] If the second dry condition is not met, the system will operate according to the set high temperature condition, specifically:

[0097] At running time T max Compare the real-time temperature F with the first temperature F1 and the maximum temperature F max ,as follows:

[0098] When F<F1, continue normal cycle heating operation;

[0099] When F1≤F≤F max When the power is on, it runs at half power cycle heating;

[0100] When F>F max When the temperature is low, the circulating heating stops and the fan continues to run to supply air to the interior;

[0101] If the second drying condition is met, the step of drying clothes for a set time is executed, specifically:

[0102] Get the real-time running time T and determine the closest time slot T x, and the time slot T x The time value satisfies the real-time running time T<time slot T x Time value < running time T max , where x = 1, 2, 3...x, the time intervals between adjacent time slots are the same, and the system continues to operate according to the set high-temperature working conditions until the time value calibrated by the time slot Tx, and then executes the cooling end step.

[0103] For example, time slots T1, T2, T3, T4...T x The time values ​​set are 60min, 70min, 80min, 90min...150min respectively. When the real-time running time of the dryer is T=75min, the second dry judgment condition is met. Then the closest time slot is determined to be T3=80min. The dryer continues to dry for an additional period of time to 80min. Because, except for arid areas, high temperature often means high humidity. High-humidity air will reduce the drying efficiency of the dryer, affect the detection of the temperature in the drum, and cause it to be mistakenly judged as dry. Taking into account that the main audience of domestic dryers is mainly concentrated in the southeast coastal areas, the design here can improve the user experience. Due to the existence of temperature protection, low air humidity will not have much impact. Run according to the set high-temperature working conditions for 80 minutes, and then execute the cooling end step.

[0104] When real-time running time T ≥ running time T max , execute the cooling end step.

[0105] The second judgment condition described in this implementation case includes:

[0106] Determine the current temperature difference ΔF ≥ L, where the current temperature difference ΔF = FF on , L is the pre-set F under high temperature conditions on The second threshold value in the ambient temperature range is set similarly to the K value setting in the first embodiment, and will not be repeated here. It includes:

[0107] When FF on ≥L, indicating that the clothes have reached a dry state;

[0108] When FF on <L, means the clothes are not dry.

[0109] This implementation case can effectively deal with the drying process under high temperature conditions. When the second drying condition is met, it is still necessary to dry for an additional period of time until the closest time slot T x , improve the accuracy of judgment and enhance user experience.

[0110] The above implementation cases all use a single temperature sensing package to ensure that the dryer has overheat protection, clothing heat preservation, and accurate dryness judgment capabilities under different working conditions (ambient temperature, humidity). The implementation case is an example of a direct-discharge dryer. The present invention can be applied to water-cooled dryers by slightly adjusting some steps according to the actual dryer type without any creativity, such as changing the real-time temperature F to obtain the temperature inside the washing machine drum and then adjusting the parameter value. At the same time, it can also be further optimized to use the temperature F used to judge the environment. on The condensation water inlet temperature is the biggest external influence on the water temperature of the water-cooled dryer.
