[0073] First, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0074] Secondly, it should be noted that in the description of the embodiments of the present invention, the terms "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0075] In addition, it should be noted that in the description of the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0076] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0077] With the continuous improvement of living standards, clothes drying equipment is increasingly appearing in people's daily lives. Clothes dryers can dry and disinfect clothes through electric heating, keeping them dry and hygienic, and improving the wearing comfort of clothes. Clothes dryers first shake and weigh the clothes, then use a compressor to heat them. An independent fan blows hot air into the dry clothes. After the compressor is turned off, cold air is blown to quickly cool the drum so that users can open the door and take out the clothes. This also simulates the air-drying process of nature, making the clothes softer to wear and not easy to damage the fabric.

[0078] Figure 1This is the installation diagram of the clothes dryer device provided by the present invention. The clothes drying process of the clothes dryer includes cold air and hot air stages. The clothes dryer includes a housing, an inner drum, and a heat pump; the housing has an embedded display panel, a water absorption device is installed on the display panel, and a temperature sensor, a humidity sensor, an integrated fan, and a cooling fan are arranged between the drums (between the inner drum and the housing). When the clothes dryer is drying clothes, the heat pump heats the air into dry hot air, and the dry hot air enters the inner drum to absorb the residual moisture of the clothes to achieve the drying effect. When the dry hot air is emitted outward, it is easy to form condensed water when it encounters a cold housing. At the same time, the formation of water vapor on the display panel of the clothes dryer will affect the touch effect, and the accumulation of water vapor may also cause the touch buttons to malfunction; electrical components with condensed water will have safety hazards and affect the service life of the electrical components. If the condensed water is not treated for a long time, it may accumulate and cause water to leak from the bottom of the machine, affecting user use. Therefore, the art needs a new dryer control method, device, and equipment to solve the above problems.

[0079] The present application provides a dryer control method, which determines whether the dryer that is currently drying clothes is prone to form condensation water by monitoring the condensation parameters. If it is determined that the current dryer is prone to form condensation water, the formation of condensation water in the dryer can be prevented by determining the cooling fan parameters after the cold air stage of the dryer ends and before the hot air stage begins, adjusting the cooling fan start-up time or the cooling fan speed according to the parameters, turning on the integrated fan and / or the water absorption device when the humidity between the drum is higher than a preset value, and turning off the auxiliary heat when the heat pump stops, etc.

[0080] The principles and features of the embodiments of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the embodiments of the present invention and are not used to limit the scope of the embodiments of the present invention.

[0081] Figure 2 is a flow chart of a first embodiment of a clothes dryer control method provided by the present invention; Figure 2 As shown, the clothes dryer control method specifically includes the following steps:

[0082] S201: Acquire a condensation parameter after the cold air stage ends, the condensation parameter including the ambient temperature, and the condensation parameter is used to indicate whether condensation water is easily formed in the dryer;

[0001] Among them, the ambient temperature included in the condensation parameters is determined based on the condenser outlet temperature and the heat pump outlet temperature. The condenser outlet and the heat pump outlet of the dryer are provided with temperature sensors for detecting the ambient temperature. The temperature sensor may be, for example, an NTC temperature sensor, the condenser outlet temperature sensor may be, for example, NTC2, and the heat pump outlet temperature sensor may be, for example, NTC3. The present invention does not impose any limitation on this.

[0002] The condensation parameter can indicate whether condensation water is easily formed in the dry clothes. Therefore, the condensation parameter is obtained after the cold air stage ends, and then it can be judged whether condensation water is easily formed in the current dryer according to the ambient temperature in the condensation parameter.

[0003] S202: If the ambient temperature is higher than a first preset temperature, it indicates that condensed water is likely to form in the clothes dryer, and according to the temperature difference between the ambient temperature and the first preset temperature, the start time of the cooling fan in the first stage of the heating stage is obtained;

[0083] Among them, the heating stage of the dryer drying clothes is divided into the first stage and the second stage; the first preset temperature is the threshold for judging that the ambient temperature is high temperature. When the ambient temperature detected by the temperature sensor is higher than the first preset temperature, that is, the condenser outlet temperature and the heat pump outlet temperature are both higher than the first preset temperature, the current environment is judged to be a high temperature environment. The first preset temperature can be, for example, 28°C.

[0084] In the above case, that is, when the current environment is a high temperature environment, condensation water is easily formed in the dryer, and the cooling fan needs to be turned on in the first stage of the heating stage to prevent the formation of condensation water. According to the temperature difference between the ambient temperature and the first preset temperature and the preset mapping relationship, the turning-on time of the cooling fan in the first stage of the heating stage can be obtained.

[0004] Optionally, in order to accurately determine the formation conditions of condensed water in the dryer, the condensation parameters also include at least one parameter of the drum temperature between the inner drum and the outer shell of the dryer, the drum humidity between the inner drum and the outer shell, and the water content of the load in the drum.

[0005] On the basis that the ambient temperature is higher than the first preset temperature, the condensation parameter satisfies at least one of the following conditions, and it is determined that the clothes dryer is prone to condensation water:

[0006] The temperature between the barrels is higher than the third preset temperature; the humidity between the barrels is higher than the second preset humidity; and the water content is higher than the preset water content.

[0007] The third preset temperature is a threshold value of the dryer drum temperature preset according to the general drum temperature when condensed water is formed in the dryer, that is, when the drum temperature of several dryers is higher than the third preset temperature, condensed water is easily formed in the dryer under the current circumstances. The second preset humidity setting principle is the same as the third preset temperature, that is, when the drum humidity of several dryers is higher than the second preset humidity, condensed water is easily formed in the dryer under the current circumstances. The water content is the water content of the clothes in the drum during the cold air stage when the dryer is drying clothes.

[0008] On this basis, if the single ambient temperature is higher than the first preset temperature, other condensation parameters must be combined to ultimately determine whether condensation water is likely to form.

[0009] In this embodiment, when condensation water is likely to form, the cooling fan needs to be turned on. According to the temperature difference between the ambient temperature and the first preset temperature and the preset mapping relationship, the turning-on time of the cooling fan in the first stage of the heating stage can be obtained.

[0010] S203: Turning on the cooling fan in the first stage according to the turn-on duration, and continuously turning on the cooling fan in a second stage of the heating stage, wherein the first stage is before the second stage.

[0011] Among them, the heating stage of the clothes dryer for drying clothes is divided into the first stage and the second stage, and the first stage is located before the second stage. When the temperature is high in the heating stage of the dryer, the hot steam dissipates outward and easily forms condensation water when it encounters the cold casing. Therefore, the cooling fan can be turned on in the heating stage of the dryer to circulate the hot air between the drums and cool down, thereby preventing the formation of condensation water. It can be understood that in the early stage of the heating stage, that is, the early stage of the first stage, due to the gradual increase in temperature, the temperature between the drums in the early stage of the heating stage generally does not reach a high temperature that is easy to form condensation water; therefore, the turning-on time of the cooling fan should be: the time point obtained by pushing the turning-on time forward from the time point at which the first stage ends, and the cooling fan is turned on from this time point and continues to be turned on until the end of the second stage of the heating stage.

[0012] The on time can be, for example, 8 minutes, and the first stage can be, for example, 25 minutes. It is understandable that, in this case, the first stage of the heating stage ends at the 25th minute, and the cooling fan on time point is a time point obtained by pushing forward 8 minutes from the time point at the end of the first stage, that is, the cooling fan is turned on at the 17th minute of the heating stage, and is kept on until the end of the second stage of the heating stage.

[0013] The clothes dryer control method provided in this embodiment determines whether condensation water is easy to form in the clothes dryer according to the condensation parameters. If condensation water is easy to form in the current clothes dryer, the ambient temperature is obtained after the cold air ends. When the ambient temperature is higher than the first preset temperature, the opening time of the cooling fan in the first heating stage is obtained according to the temperature difference between the ambient temperature and the first preset temperature, and the cooling fan is turned on in the first heating stage according to the opening time. This method avoids the problems of affecting the touch effect of the dryer display panel, prone to malfunction of touch buttons, affecting the service life of electrical components, affecting user use, etc. caused by the formation of condensation water in the clothes dryer, and improves the user experience and the drying efficiency of the clothes dryer.

[0014] Figure 3 is a flow chart of a second embodiment of a clothes dryer control method provided by the present invention; Figure 3 exist Figure 2 The method of preventing condensation from forming in clothes dryers is described in detail on the basis of Figure 3 As shown, the method includes:

[0015] S301: Acquire the ambient temperature after the cold wind stage ends.

[0016] Among them, after the cold air stage of drying clothes in the dryer ends, the ambient temperature is detected according to the temperature sensors at the condenser outlet and the heat pump outlet of the dryer. The temperature sensor can be, for example, an NTC temperature sensor, the condenser outlet temperature sensor can be, for example, NTC2, and the heat pump outlet temperature sensor can be, for example, NTC3. The present invention does not impose any restrictions on this.

[0017] S302: Determine whether the ambient temperature is higher than a first preset temperature; if so, execute S303; if not, the process ends.

[0018] The first preset temperature is a threshold for determining that the ambient temperature is high temperature. When the ambient temperature detected by the temperature sensor is higher than the first preset temperature, the current environment is determined to be a high temperature environment. It is understandable that if the environment is a high temperature environment before the heating stage after the cold air stage of the dryer ends, the cooling fan needs to be turned on in the first stage of the heating stage to prevent the formation of condensed water.

[0019] S303: Acquire a candidate duration according to a temperature difference between the ambient temperature and the first preset temperature and a preset mapping relationship.

[0020] The first preset temperature may be, for example, 28° C. It is understandable that when the ambient temperature detected by the temperature sensor is higher than 28° C., the current environment is a high temperature environment. According to the temperature difference between the ambient temperature and the first preset temperature and the preset mapping relationship, the candidate duration for turning on the cooling fan in the first stage of the heating stage may be obtained.

[0021] The preset mapping relationship can be, for example: taking the temperature value of the ambient temperature higher than the first preset temperature as the candidate duration for turning on the cooling fan in the first stage of the heating stage; if the currently detected ambient temperature is 36 degrees and the first preset temperature is 28°C, then the candidate duration for turning on the cooling fan in the first stage of the heating stage is 8 minutes.

[0022] S304: Determine whether the candidate duration is less than the first stage duration; if so, execute S305; if not, execute S306.

[0023] It can be understood that the candidate duration is the same as or different from the duration of the first stage, and the corresponding cooling fan is turned on for a different duration in the first stage of the heating stage.

[0024] S305: Using the candidate duration as the activation duration.

[0025] Among them, according to the temperature value of the ambient temperature higher than the first preset temperature as the candidate duration for turning on the cooling fan in the first stage of the heating stage, when the candidate duration is less than the first stage duration, the candidate duration is used as the turn-on duration. For example, if the first preset temperature is 28°C and the current ambient temperature is 36°C, the candidate duration is 8 minutes, and the turn-on duration of the cooling fan in the first stage of the heating stage is 8 minutes. In this case, the calculation formula for the turn-on duration of the cooling fan is: T1=X+(T-28); T1 is the total time the cooling fan is turned on in the heating stage, X is the time the cooling fan is turned on in the second stage of the heating stage, and (T-28) is the candidate duration, that is, the turn-on duration of the cooling fan in the first stage of the heating stage.

[0026] S306: Using the duration of the first stage as the activation duration.

[0027] Among them, according to the temperature value of the ambient temperature higher than the first preset temperature as the candidate duration for turning on the cooling fan in the first stage of the heating stage, when the candidate duration is greater than or equal to the first stage duration, the cooling fan is turned on throughout the first stage, that is, the first stage duration is used as the turn-on duration. For example, if the first preset temperature is 28°C, the current ambient temperature is 53°C, and the first stage duration is 25 minutes, the cooling fan is turned on throughout the first stage, and when the ambient temperature is higher than 53°C, the cooling fan is also turned on throughout the first stage. In this case, the cooling fan turn-on duration calculation formula is: T1=X+T; T1 is the total time the cooling fan is turned on in the heating stage, X is the time the cooling fan is turned on in the second stage of the heating stage, and T is the first stage duration of the heating stage.

[0028] S307: Obtain the time difference between the first stage and the opening duration.

[0029] When the cooling fan is not fully turned on in the first stage of the heating phase, there is a time difference between the duration of the cooling fan being turned on in the first stage of the heating phase and the duration of the first stage.

[0030] S308: Determine the opening time corresponding to the opening duration according to the time difference.

[0031] Among them, when the temperature of the dryer is high during the heating stage, the hot steam dissipates outward and encounters the cold casing, which easily forms condensed water. Therefore, during the heating stage of the dryer, the cooling fan can be turned on to circulate the hot air between the drums and cool them down, thereby preventing the formation of condensed water. It can be understood that at the beginning of the heating stage, that is, at the beginning of the first stage, due to the gradual increase in temperature, the temperature between the drums at the beginning of the heating stage generally does not reach a high temperature that is easy to form condensed water. Therefore, the cooling fan is generally not turned on at the beginning of the heating stage. The turning-on time of the cooling fan should be: the time point obtained by pushing the turning-on time forward from the end time of the first stage, and this time point is the turning-on time of the cooling fan.

[0032] S309: Turning on the cooling fan in the first stage according to the turn-on time and the turn-on duration, so that the cooling fan is turned on continuously in the first stage and the second stage.

[0033] The on time can be, for example, 8 minutes, and the first stage can be, for example, 25 minutes. It is understandable that in this case, the first stage of the heating stage ends at the 25th minute, and the cooling fan on time point is: the time point obtained by pushing forward 8 minutes from the time point at the end of the first stage, that is, the cooling fan is turned on at the 17th minute of the heating stage, and is continuously turned on until the end of the second stage of the heating stage, so that the cooling fan is continuously turned on in the first stage and the second stage.

[0034] Optionally, if the ambient temperature is higher than the first preset temperature, the method further includes:

[0035] According to the temperature difference between the ambient temperature and the first preset temperature, the increase value of the fan speed of the cooling fan is obtained; according to the increase value of the fan speed and the original fan speed, a new fan speed is obtained; in the first stage, the cooling fan is kept off, and in the second stage, the cooling fan is controlled to be continuously turned on with the new fan speed.

[0036] The fan speed increase method of the cooling fan can be, for example, that when the ambient temperature increases by one degree compared to the first preset temperature, the fan speed of the cooling fan increases by 100 revolutions. If the current first preset temperature is 28°C, the speed calculation formula of the cooling fan after adjustment in this case is: N1=N+(T-28)*100, where N1 is the speed of the cooling fan after adjustment and N is the preset speed of the cooling fan.

[0037] The clothes dryer control method provided in this embodiment determines whether condensation water is easy to form in the clothes dryer according to the condensation parameters. If the current clothes dryer is easy to form condensation water, the ambient temperature is obtained after the cold air ends. When the ambient temperature is higher than the first preset temperature, the candidate duration is obtained according to the temperature difference between the ambient temperature and the first preset temperature and the preset mapping relationship, and then the opening duration of the cooling fan in the first heating stage is obtained, or the cooling fan speed is adjusted according to the ambient temperature and the first preset temperature to prevent the formation of condensation water in the clothes dryer. This method avoids the problems of affecting the touch effect of the dryer display panel, prone to malfunction of touch buttons, affecting the service life of electrical components, affecting user use, etc. caused by the formation of condensation water in the clothes dryer, and improves the user experience and the drying efficiency of the clothes dryer.

[0038] Figure 4 is a flow chart of a third embodiment of a clothes dryer control method provided by the present invention; Figure 4 exist Figure 3 , 2 On this basis, the methods for preventing condensation from forming in clothes dryers are described in detail, such as Figure 4 As shown, the method includes:

[0039] S401: Obtain the temperature and / or humidity between cylinders.

[0040] Among them, because the temperature and humidity in the drum of the dryer are constantly changing during the cold air stage and the heating stage, a temperature sensor and a humidity sensor are set in the drum to obtain the temperature and humidity in the drum in real time.

[0041] S402: Determine whether the temperature between drums is higher than the second preset temperature, if yes, execute S403, if no, execute S404.

[0042] Among them, the second preset temperature is the drum temperature threshold at which condensed water is easily formed when the dryer is drying clothes. If the current real-time measured drum temperature is higher than the second preset temperature, it can be determined that condensed water is easily formed in the dryer under the current circumstances.

[0043] S403: Turn on the integrated fan corresponding to the display device.

[0044] Among them, in order to prevent the formation of condensation water when the dryer is drying clothes, an integrated fan is installed inside the dryer display panel or at the junction of the upper side of the dryer drum and the display panel. When it is detected that the current drum temperature is higher than the second preset temperature, the integrated fan is controlled to turn on to prevent the formation of condensation water in the dryer.

[0045] S404: Determine whether the humidity between the drums is higher than the first preset humidity. If so, execute S405; if not, the process ends.

[0046] Among them, the first preset humidity is the inter-drum humidity threshold at which condensation water is easily formed when the dryer is drying clothes. If the current real-time measured inter-drum humidity is higher than the first preset humidity, it can be determined that the dryer is prone to form condensation water under the current circumstances.

[0047] S405: Turn on the water absorption device corresponding to the display device and / or turn on the accidental touch function of the display device.

[0048] Among them, the formation of water vapor on the dryer display panel will affect the touch effect, and the accumulation of water vapor may also cause malfunction of the touch buttons. Therefore, when the humidity in the drum is higher than the first preset humidity, it is necessary to turn on the water absorption device corresponding to the display device and / or turn on the false touch function of the display device.

[0049] The water absorption device can be, for example, a small water absorption material device controlled by a relay and installed on the back of the display panel. When the humidity between the drums is higher than the first preset humidity, the relay is triggered to control the water absorption device to start. The false touch function includes: when the dryer is running, monitoring whether the power button or the start button is actuated at the same time as other buttons for more than 200ms. If so, the dryer is controlled not to ring the above key value.

[0050] In the clothes dryer control method provided in this embodiment, when the temperature between the drums is higher than the second preset temperature and the humidity between the drums is higher than the first preset humidity, condensed water is easily formed in the clothes dryer. This method avoids the problems of water vapor on the display device affecting the touch effect of the display panel and the erroneous operation of the touch buttons caused by the formation of condensed water by turning on the integrated fan corresponding to the display device, the water absorption device corresponding to the display device, and / or turning on the false touch function of the display device, thereby improving the user experience and the drying efficiency of the clothes dryer.

[0051] Figure 5 is a flow chart of a fourth embodiment of a clothes dryer control method provided by the present invention; Figure 5 exist Figure 4 , 3 , 2, the method of preventing condensation water from forming in the clothes dryer is described in detail, such as Figure 5 As shown, the method includes:

[0052] S501: During the heating phase, determine whether the condenser outlet temperature drops by N degrees within a second preset time period. If so, execute S502; if not, the process ends.

[0053] The second preset duration is the duration for determining whether the heat pump is stopped due to physical protection. The reason for the heat pump stopping due to physical protection may be, for example, heat pump failure, heat pump power failure, heat pump overheating, etc. This application does not limit the reason for the heat pump stopping.

[0054] S502: Determine whether the heat pump is in a stopped state.

[0055] Among them, when it is monitored that the condenser outlet temperature drops by N degrees in the second preset time, it is determined that the heat pump is in a physical stop state. For example, when the second preset time is 5 minutes, it is monitored that the condenser outlet temperature drops by more than 15°C within 5 minutes, it is determined that the compressor is stopped due to physical protection. In addition, if the compressor stop is not detected within 5 minutes, it is set to restart the timing for 5 minutes when the temperature drops by more than 5°C, and the temperature drop value in the previous 5 minutes is included in the cumulative temperature drop value, and it is re-determined whether the heat pump is stopped due to physical protection.

[0056] S503: Control the auxiliary heating to turn off.

[0057] Among them, if the compressor stops, condensation water is easy to form when only auxiliary heat is turned on, so it is necessary to control the auxiliary heat to be turned off to prevent the formation of condensation water.

[0058] In the clothes dryer control method provided by this embodiment, during the heating stage, when the condenser outlet temperature drops by N degrees in the second preset time, the heat pump is in a stopped state. When the heat pump is stopped and only the auxiliary heat is turned on, condensation water is likely to form. This method controls the auxiliary heat to be turned off, thereby preventing the formation of condensation water in this case, thereby avoiding the water vapor on the display device affecting the touch effect of the display panel, causing the touch button to malfunction, affecting the service life of the electrical components, affecting the user's use, and other issues, thereby improving the user experience and the drying efficiency of the clothes dryer.
