[0032] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that the embodiments are only used to explain the technical principles of the present application, and are not intended to limit the scope of protection of the present application. For example, although the specific embodiments described below are described in conjunction with a clothes dryer, the technical solutions of the present application are also applicable to other laundry treatment devices, such as a washer-dryer, etc. Such adjustments and changes in application objects do not deviate from the principles and scope of the present application, and should be limited within the scope of protection of the present application.

[0033] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that in the description of the present application, although the steps of the control method of the present application are described in a specific order in the present application, these orders are not limiting, and those skilled in the art can perform the steps in different orders without deviating from the basic principles of the present application.

[0034] It should be noted that in the description of the present application, the terms indicating the direction or positional relationship such as "inner", "outer", "upper", "lower", "top", "bottom", etc. are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] In addition, it should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "provided", "connected", "mounted" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0036] Based on the background technology, the present application provides a control method of a clothes processing device and the clothes processing device, aiming to obtain the temperature between the cylinders, when the temperature between the cylinders is too low or too high, the fan can be started to blow air towards the condenser and the evaporator respectively, and the air is blown into the box and the outer cylinder to increase or decrease the temperature, so that the inner cylinder of the clothes processing device is in a stable temperature environment, and the drying efficiency is not affected by the external temperature.

[0037] Specifically, as shown in the drawings, Figure 1 The present application provides a clothes processing device with drying function, comprising a box 1, an outer cylinder 2, an evaporator 5, a condenser 6, a fan 7 and a first temperature sensor 8 installed in the box 1, the first temperature sensor 8 is used to detect the temperature between the box 1 and the outer cylinder 2, the fan 7 can blow air towards the evaporator 5 and the condenser 6, and the air is blown into the box 1 and the outer cylinder 2.

[0038] Exemplarily, as shown in the drawings, Figure 1 The clothes dryer of the present application is arranged in the vertical direction, the outer cylinder 2 is installed in the box 1, the inner cylinder (not shown in the drawing) is installed in the outer cylinder 2, the air outlet and the air return of the circulating air duct 3 are communicated with the front end and the rear end of the inner cylinder respectively, the evaporator 5 and the condenser 6 and the fan 7 are arranged in the circulating air duct 3, and the circulating fan (not shown in the drawing) is also arranged in the circulating air duct 3, when the clothes dryer executes the drying program, the circulating fan starts to run, under the action of the circulating fan, the hot and humid air in the inner cylinder flows through the air return of the circulating air duct 3, the evaporator 5 absorbs the heat of the hot and humid air and can condense the water vapor in the hot and humid air, so as to condense the hot and humid air into dry and cold air, the dry and cold air flows through the condenser 6 for heating, so as to become dry and hot air, and then enters the inner cylinder through the air outlet of the circulating air duct 3 to dry the clothes in the inner cylinder.

[0039] Based on the background technology, when the clothes dryer dries the clothes, the drying temperature in the inner cylinder needs to be kept at the preset drying temperature to maximize the drying efficiency of the clothes dryer, when the external environment of the clothes dryer is too low or too high, the inner cylinder exchanges heat with the external environment, when the external environment temperature is too low, the drying temperature in the inner cylinder is lower than the preset drying temperature, which will cause the clothes to be not dried enough and increase the drying time, when the drying temperature in the inner cylinder is higher than the preset drying temperature, the clothes dryer will cause the drying program to be abnormal due to the high temperature, mainly because the initial drying temperature, i.e. the environment temperature, is high, which leads to high temperature in the cylinder, and further leads to termination of the drying program, thereby reducing the drying efficiency of the clothes dryer.

[0040] The space between the cabinet 1 and the outer cylinder 2 of the clothes dryer is referred to as the inter-cylinder region, which is an intermediate medium for heat exchange between the inner cylinder and the external environment. The first temperature sensor 8 is installed in the inter-cylinder region to detect the temperature between the cabinet 1 and the outer cylinder 2, referred to as the inter-cylinder temperature. The circulating air duct 3 is connected to the inter-cylinder region through the air supply duct 4. The fan 7 can rotate to blow air towards the evaporator 5 or the condenser 6, and can blow air into the air supply duct 4 and into the inter-cylinder region. The air supply duct 4 is controlled by an electromagnetic valve. When the fan 7 is on, the air supply duct 4 is open. When the fan 7 is off, the air supply duct 4 is closed. When the external environment temperature is too low, the inter-cylinder temperature is lowered through heat exchange with the external environment. At this time, the fan 7 is turned on to blow air towards the condenser 6, and hot air is blown into the inter-cylinder region through the air supply duct 4, thereby warming the inter-cylinder region. When the external environment temperature is too high, the inter-cylinder temperature is raised through heat exchange with the external environment. At this time, the fan 7 is turned on to blow air towards the evaporator 5, and cold air is blown into the inter-cylinder region through the air supply duct 4, thereby cooling the inter-cylinder region. This can keep the inter-cylinder temperature within an appropriate temperature range, isolate the inner cylinder from the external environment, effectively avoid the influence of the external environment temperature on the drying temperature of the inner cylinder, and ensure the drying efficiency of the clothes treatment equipment.

[0041] It should be noted that the present application does not limit the number of fans 7. For example, a person skilled in the art can also set one fan 7 on each side of the evaporator 5 and the condenser 6, and blow air towards the evaporator 5 and the condenser 6 through the two fans 7, etc. Such adjustment and change of the specific number of fans 7 and the specific structure form do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0042] It should be noted that the present application does not limit the number of air supply ducts 4. For example, a person skilled in the art can also set one air supply duct 4 near the evaporator 5 and the condenser 6, and blow air towards the evaporator 5 and the condenser 6 through the two air supply ducts 4, etc. Such adjustment and change of the specific number of air supply ducts 4 and the specific structure form do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0043] It should be further explained that the present application does not limit the number and position of the first temperature sensor 8, for example, a person skilled in the art can set multiple first temperature sensors 8 in the inter-cylinder area and set the multiple first temperature sensors 8 at different positions in the inter-cylinder area, so as to more accurately detect the inter-cylinder temperature, and the adjustment and change of the specific structure form of the specific number and position of the first temperature sensor 8 do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0044] On the other hand, based on the above-described clothes dryer, the present application further provides a control method of the clothes dryer, as shown in the following steps. Figure 2

[0045] S100: Obtain the temperature between the cabinet 1 and the outer cylinder 2, that is, the inter-cylinder temperature T0.

[0046] Exemplarily, one first temperature sensor 8 is installed in the inter-cylinder area of the present application to detect the inter-cylinder temperature.

[0047] It should be noted that the number of the first temperature sensor 8 of the present application is not fixed, for example, a person skilled in the art can also set multiple first temperature sensors 8 in the inter-cylinder area, and the average value of the multiple inter-cylinder temperatures detected by the multiple first temperature sensors 8 is transmitted to the controller as the inter-cylinder temperature, and the flexible adjustment and change do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0048] It should be further explained that the value of the inter-cylinder temperature obtained by the first temperature sensor 8 of the present application is an ad value, that is, the value of the analog signal converted into a digital signal, the ad value corresponds to different resistance values, the first temperature sensor 8 detects different temperatures corresponding to different resistance values, that is, different ad values, the upper limit of the ad value is 255, and the minimum is 0, which respectively correspond to high temperature 120 degrees and low temperature below-30 degrees.

[0049] Next, the control method of the present application will be described in the following with respect to the temperature value corresponding to the ad value of the inter-cylinder temperature obtained by the first temperature sensor 8.

[0050] S200: Selectively start the fan 7 according to the inter-cylinder temperature T0.

[0051] That is, whether to start the fan 7 is judged according to whether the inter-cylinder temperature is too high or too low, or within the appropriate temperature range.

[0052] Exemplarily, as shown in the following steps, the step S200 includes steps S210 to S230. Figure 3

[0053] ​​S210: compare the inter-cylinder temperature T0 with the first preset value T1 and the second preset value T2 respectively.

[0054] That is, the preset value of the inter-cylinder temperature is a temperature interval, the preset value of the inter-cylinder temperature is between the first preset value T1 and the second preset value T2, and the first preset value T1 is less than the second preset value T2. Exemplarily, the preset value of the inter-cylinder temperature T1 is 20℃, T2 is 30℃, and the inter-cylinder temperature interval is between 20℃ and 30℃. When the inter-cylinder temperature T0 is within the temperature interval, the inter-cylinder temperature is appropriate and does not affect the drying temperature of the inner cylinder. When the inter-cylinder temperature T0 exceeds the temperature interval, the inter-cylinder temperature T0 is less than 20℃ or greater than 30℃, the inter-cylinder temperature is too high or too low, and the drying temperature of the inner cylinder is affected.

[0055] S230: if the inter-cylinder temperature T0 is greater than or equal to the first preset value T1 and less than or equal to the second preset value T2, the fan 7 is not started.

[0056] That is, the inter-cylinder temperature T0 is between 20℃ and 30℃, the inter-cylinder temperature is at an appropriate temperature, and the inter-cylinder area does not need to be heated or cooled. At this time, the fan 7 is not started, and the electromagnetic valve to which the air supply is sent is closed.

[0057] S220: if the inter-cylinder temperature T0 is less than the first preset value T1 or greater than the second preset value T2, the fan 7 is started.

[0058] That is, the inter-cylinder temperature T0 exceeds the temperature interval, when the inter-cylinder temperature T0 is less than 20℃ or greater than 30℃, the inter-cylinder temperature is too high or too low, which affects the drying temperature of the inner cylinder, so the fan 7 needs to be started to blow air to the inter-cylinder area to heat or cool.

[0059] Exemplarily, as shown in Figure 3 , the step S220 includes steps S221 to S224.

[0060] S221: calculate the difference between the inter-cylinder temperature T0 and the first preset value T1 or the second preset value T2.

[0061] Exemplarily, the inter-cylinder temperature T0 is 17℃, the difference between T0 and T1 is 3℃, or the inter-cylinder temperature T0 is 36℃, the difference between T0 and T1 is 6℃, and the difference between the inter-cylinder temperature T0 and the first preset value T1 or the second preset value T2 is the absolute value, that is, the difference Δ = |T0-T1| or Δ = |T0-T2|.

[0062] S222: obtain the preset speed of the fan 7 corresponding to the difference Δ.

[0063] Exemplarily, the preset wind speed of the fan 7 is divided into three grades of wind speed, gear = difference Δ / 5, and then rounding integer +1, for example, when the inter-drum temperature T0 is 17℃, the difference between T0 and T1 is 3℃, 3 / 5 = 0.6, rounding integer 0 +1 is 1st gear, when the inter-drum temperature T0 is 36℃, the difference between T0 and T1 is 6℃, 6 / 5 = 1.2, rounding integer 1 +1 is 2nd gear, and so on. The greater the difference is, the higher the gear is, and the faster the rotating speed of the fan 7 is, so that the inter-drum area can be rapidly cooled or heated.

[0064] It should be noted that the division of the gear of the fan 7 of the present application is not limited, for example, the skilled in the art can also set the gear of the fan 7 to two or four gears, and the like. Such flexible adjustment and change does not deviate from the principle and scope of the present application, and should be limited within the protection scope of the present application.

[0065] It should be further noted that the corresponding relationship between the preset rotating speed of the fan 7 of the present application and the difference is not limited, for example, the skilled in the art can also set the gear to gear = difference Δ / 6, and then rounding integer +1, and the like. Such flexible adjustment and change does not deviate from the principle and scope of the present application, and should be limited within the protection scope of the present application.

[0066] S223: If the inter-drum temperature T0 is greater than the second preset value T2, the fan 7 is made to blow air towards the evaporator 5 at the preset rotating speed.

[0067] That is to say, when the inter-drum temperature T0 is greater than 30℃, the inter-drum temperature T0 is too high and exceeds the maximum value of the temperature range, for example, the inter-drum temperature T0 is 36℃, at this time the fan 7 is started and blows air towards the evaporator 5 at the 2nd gear preset rotating speed, the air passing through the evaporator 5 is cooled to become cold air, the cold air enters the inter-drum area through the air supply air duct 4, so as to cool the inter-drum area and maintain the inter-drum temperature within the preset value.

[0068] S224: If the inter-drum temperature T0 is less than the first preset value T1, the fan 7 is made to blow air towards the condenser 6 at the preset rotating speed.

[0069] That is to say, when the inter-drum temperature is less than 20℃, the inter-drum temperature T0 is too low and is lower than the minimum value of the temperature range, for example, the inter-drum temperature T0 is 17℃, at this time the fan 7 is started and blows air towards the condenser 6 at the 1st gear preset rotating speed, the air passing through the condenser 6 is heated to become hot air, the hot air enters the inter-drum area through the air supply air duct 4, so as to heat the inter-drum area and maintain the inter-drum temperature within the preset value.

[0070] The first temperature sensor 8 of the present application detects that the inter-cylinder temperature T0 exceeds the preset value of the inter-cylinder temperature, in order to ensure the accuracy of the detection signal, prevent accidental abnormal values of the first temperature sensor 8 caused by signal interference such as electromagnetic interference, and the detection signal value needs to be sustained for 6S before the inter-cylinder temperature T0 is determined to exceed the preset value of the inter-cylinder temperature.

[0071] It should be noted that the duration of the detection signal value of the first temperature sensor 8 of the present application is not fixed, for example, the skilled person can also set the duration of the detection signal value to 7S or 8S, etc. Such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0072] It should be noted that the present application does not limit the temperature values of the first preset value T1 and the second preset value T2, for example, the skilled person can also set the first preset value T1 to 15℃, or set the second preset value T2 to 25℃, etc. Such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0073] S300: Obtain the temperature in the inner cylinder, i.e. the cylinder temperature TN.

[0074] Exemplarily, a second temperature sensor (not shown in the figure) is installed in the inner cylinder of the present application to detect the cylinder temperature TN.

[0075] It should be noted that the number of second temperature sensors of the present application is not fixed, for example, the skilled person can also set multiple second temperature sensors in the inner cylinder, etc. The average value of the multiple cylinder temperatures TN detected by the multiple second temperature sensors is transmitted to the controller as the cylinder temperature TN. Such flexible adjustment and change does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0076] It should also be noted that the value of the cylinder temperature TN obtained by the second temperature sensor of the present application is an ad value, i.e. the value of the analog signal converted into a digital signal. The ad value corresponds to different resistance values, and the second temperature sensor detects different temperatures corresponding to different resistance values, i.e. different ad values. The upper limit of the ad value is 255, and the minimum is 0, which respectively corresponds to high temperature 120 degrees and low temperature-30 degrees or below.

[0077] Next, the control method of the present application will be described with respect to the temperature value corresponding to the ad value of the cylinder temperature obtained by the second temperature sensor.

[0078] S400: When the change amplitude of the cylinder temperature TN is greater than the set value, the clothes treatment equipment is prompted that the second temperature sensor has failed.

[0079] That is, the change range of the drum temperature TN is too large, when the change range exceeds the set value, that is, the drum temperature TN jumps, the ad value corresponding to the drum temperature TN detected by the second temperature sensor suddenly rises to a very high value or suddenly drops to a very low value, at this time, the clothes dryer will issue a prompt that the second temperature sensor is faulty.

[0080] Exemplarily, the drum temperature TN is compared with the first alarm preset value TJ1 and the second alarm preset value TJ2 respectively.

[0081] That is, the alarm preset value of the drum temperature TN is a temperature interval, the alarm preset value of the drum temperature TN is between the first alarm preset value TJ1 and the second alarm preset value TJ2, and the first alarm preset value TJ1 is less than the second alarm preset value TJ2, exemplarily, the alarm preset value of the drum temperature TN is-20℃, the corresponding ad value is 245, T2 is 98℃, the corresponding ad value is 5, the alarm preset value interval of the drum temperature TN is between-20℃ and 98℃, when the drum temperature TN is in the alarm preset value interval, the clothes dryer will not issue a prompt that the second temperature sensor is faulty, when the drum temperature TN exceeds the alarm preset value interval, when the drum temperature TN is less than-20℃ or greater than 98℃, the clothes dryer will issue a prompt that the second temperature sensor is faulty.

[0082] If the drum temperature TN is less than the first alarm preset value TJ1, the clothes dryer is caused to issue a prompt that the second temperature sensor is open-circuit fault.

[0083] That is, the drum temperature TN detected by the second temperature sensor is less than-20℃, at this time, the clothes dryer will issue a prompt that the second temperature sensor is open-circuit fault, so that the maintenance personnel can quickly find the fault point of the circuit and facilitate maintenance.

[0084] If the drum temperature TN is greater than the second alarm preset value TJ2, the clothes dryer is caused to issue a prompt that the second temperature sensor is short-circuit fault.

[0085] That is, the drum temperature TN detected by the second temperature sensor is greater than 98℃, at this time, the clothes dryer will issue a prompt that the second temperature sensor is short-circuit fault, so that the maintenance personnel can quickly find the fault point of the circuit and facilitate maintenance.

[0086] It should be noted that the present application does not limit the temperature values of the first alarm preset value TJ1 and the second alarm preset value TJ2, for example, the first alarm preset value TJ1 can be set to-10℃, or the second alarm preset value TJ2 can be set to 95℃, and the like, such flexible adjustment and change do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.
