Description

Technical Field

[0001] The present application relates to the field of electrical appliance technology, and in particular to a clothes dryer control method, device, clothes dryer and computer-readable storage medium. Background Art

[0002] In the prior art, clothes dryers use condensation drying technology. In this technology, the dryer evaporates the moisture from the clothes by heating the air. The evaporated moisture will exist in the form of water vapor and will be carried to the condensation system inside the dryer. The function of the condensation system is to help convert this water vapor into water for easy discharge. The condensation system usually includes a cooling device, which cools the water vapor back to liquid water by reducing the temperature of the vapor. Then, the liquid water will be collected in a water tank or discharged through a drainage pipe.

[0003] Among them, various types of refrigerants can be used in the condensation system. When the water vapor reaches the condensation system, the refrigerant absorbs the heat of the water vapor, converts the water vapor into condensed water, and then discharges it. After that, the condensation system sends the heated refrigerant to the cooling module in the condensation system for cooling, and then sends the cooled refrigerant back to the position of heat exchange with the water vapor in the condensation system, and the cycle is repeated to achieve clothing drying.

[0004] It can be seen that in the condensing system, the refrigerant is very important as a medium for heat exchange. The refrigerant in the condensing system can be some special chemicals sealed in the condensing system in advance or cold water.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature.

[0044] In order to enable any person skilled in the art to implement and use the present application, the following description is provided. In the following description, details are listed for the purpose of explanation. It should be understood that those of ordinary skill in the art will recognize that the present application can be implemented without using these specific details. In other examples, known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the present application obscure. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0045] The present application provides a clothes dryer control method, device, equipment and storage medium, which are described in detail below.

[0046] See also Figure 1 , Figure 1 1 is a schematic diagram of a scene of a clothes dryer control system provided in an embodiment of the present application, and the clothes dryer control system may include a clothes dryer 100. Figure 1 The dryer 100 in the embodiment can execute the relevant control logic stored inside to execute the dryer control method in the present application.

[0047] The clothes dryer 100 may be a device that can only dry clothes, or may be a device that can wash and dry clothes in one, and the specific embodiments of the present application do not limit this.

[0048] It should be noted that Figure 1 The scenario diagram of the dryer control system shown is only an example. The dryer control system and scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can know that with the evolution of the dryer control system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0049] like Figure 2 As shown, Figure 2This is a flow chart of an embodiment of a method for controlling a clothes dryer in an embodiment of the present application. The method is applied to a target device having a clothes drying function. The target device includes a heat exchanger and a target valve for controlling the flow of condensing water. The target valve is connected to the heat exchanger through a pipeline. The method specifically includes the following steps 201 to 203:

[0050] 201. If the target device is in working state, obtain the current temperature of the heat exchanger.

[0051] In an embodiment of the present application, the target device may be a clothes dryer as described above or a washer-dryer with a clothes drying function, and the embodiment of the present application is not limited thereto.

[0052] In addition, the heat exchanger can be a heat exchange module in the condensing device of the target device for exchanging heat with water vapor generated when clothes are dried. The condensing device can be connected to an external water source, such as a tap water pipe, and the tap water introduced from the outside is introduced into the heat exchanger through a pipe, so that the tap water is used as condensation water.

[0053] The target valve may be provided on the pipeline to control the flow rate of the condensing water into the heat exchanger.

[0054] When the user turns on the device to dry clothes, the heat sensor in the heat exchanger starts working to obtain the current temperature of the condenser tube in the heat exchanger.

[0055] 202. If the current temperature is greater than or equal to a first temperature threshold, determine an elapsed time to reach the first temperature threshold.

[0056] In the embodiment of the present application, the first temperature threshold can be set according to actual conditions, and the embodiment of the present application does not limit it.

[0057] In addition, the consumed time may be the time consumed after the target device starts working until the current temperature reaches the first temperature threshold. Specifically, after the target device is turned on, timing may be performed. When the current temperature reaches the first temperature threshold, the timing time is obtained, and the timing time is the consumed time.

[0058] 203. According to the current temperature and the elapsed time, the opening and closing of the target valve is controlled to control the flow rate of the condensing water flowing into the heat exchanger.

[0059] In an embodiment of the present application, after obtaining the time consumed for the current temperature to reach the first temperature threshold, the temperature change rate can be determined based on the temperature change value of the current temperature and the consumed time. If the determined temperature change rate has been rising, it proves that the heat exchange demand is large. At this time, the opening and closing angle of the target valve can be increased to allow more cold water to flow into the condensing device to condense the water vapor generated by drying. If the temperature change rate begins to decrease or is always in a decreasing state, the opening and closing degree of the target valve can be gradually reduced, thereby reducing the condensation water flowing into the condensing device and avoiding water waste.

[0060] In addition, since the refrigerant is replaced with water in the embodiment of the present application instead of using the traditional chemical refrigerant, there is no need to consider the refrigerant leakage, which may cause the problem of unstable condensation effect.

[0061] It should also be noted that in the embodiment of the present application, the rate of temperature change can be set as a linear function with the valve opening degree, and the valve opening degree can be obtained by inputting the temperature change rate into the linear function. Among them, the linear function can be set according to the actual situation, and the embodiment of the present application does not limit it.

[0062] In summary, the clothes dryer control method provided by the present application can use water as a refrigerant to replace conventional chemical refrigerants, which is convenient for replenishment. At the same time, when the device is working, the current temperature of the heat exchanger and the time elapsed when the current temperature reaches the first temperature threshold can be obtained first, and the flow rate of condensation water can be controlled according to the current temperature and the time elapsed, so as to avoid continuous injection of cold water for condensation and prevent water waste.

[0063] In order to better implement the embodiment of the present application, in one embodiment of the present application, the opening and closing of the target valve is controlled according to the current temperature and the elapsed time, including:

[0064] According to the consumed time, the valve opening change time corresponding to the target valve is determined; according to the current temperature and the valve opening change time, the opening and closing of the target valve is controlled.

[0065] In the above embodiment, a solution is provided for controlling the opening and closing of the valve according to the current temperature and the elapsed time. In order to accurately control the opening and closing degree of the valve, the embodiment of the present application also provides an implementation method.

[0066] Specifically, in an embodiment of the present application, after obtaining the consumed time taken for the current temperature to reach the first temperature threshold, the valve opening change time corresponding to the target valve can be calculated based on the consumed time. Among them, the valve opening change time can be defined as the time when the target valve is in a non-closed stage. In other words, the time elapsed after the target valve is opened to when it is completely closed. The purpose of the valve opening change time is to control the total time when the valve is open, which is used to control the total flow rate of condensing water as a whole. Of course, the valve opening change time is a dynamic time. If the rate of change of the current temperature begins to decrease rapidly, becomes a negative number, and is less than a certain value, it can be proved that there is no need to inject additional condensing water. At this time, the valve opening change time can be changed to 0, and the target valve is closed.

[0067] Among them, the longer the consumed time is, the slower the temperature rises when the condensing device exchanges heat, which means that less water vapor evaporates and the total heat exchange amount is low. Therefore, there is no need for too much condensation water. In other words, if the shorter the consumed time is, the faster the temperature rises when the condensing device exchanges heat, more water vapor evaporates and the total heat exchange amount is high. At this time, it is necessary to increase the condensation water to ensure the heat exchange efficiency. Based on this, the consumed time and the valve opening change time can be inversely proportional. The more the consumed time is, the less the valve opening change time is; the less the consumed time is, the more the valve opening change time is. The specific inverse function can be set according to the actual situation, and the embodiment of the present application does not limit it.

[0068] In order to better implement the embodiment of the present application, in one embodiment of the present application, the opening and closing of the target valve is controlled according to the current temperature and the valve opening change time, including:

[0069] Obtain the valve opening time corresponding to the target valve; determine the target opening degree of the target valve based on the current temperature, valve opening time, and valve opening change time.

[0070] The above embodiments provide a solution for controlling the opening degree of a target valve according to the current temperature and the valve opening change time; or a solution for controlling the opening degree of a target valve according to the current temperature and the elapsed time.

[0071] The embodiment of the present application also provides a solution combining the current temperature, valve opening change time and valve opening time.

[0072] In the embodiment of the present application, the valve opening time may refer to the working time of the valve. For example, the timing may start after the device is turned on, and the timing data is the valve opening time.

[0073] Specifically, in the conventional clothing drying stage, it is usually around tens of minutes. The device will automatically detect the water vapor content inside the drying chamber to determine whether the clothes are dried. Therefore, after controlling the valve opening and closing according to the current temperature and the valve opening change time, if the device continues to dry for 1 hour, 2 hours, etc., it has obviously exceeded the normal drying time. Therefore, if the working time of the device exceeds the valve opening time, it can be proved that the working time of the device is abnormal. If this happens, the device can alarm to prompt the user whether the device is abnormal. The alarm method may include the device alarming through a buzzer, or sending a message through an APP, which is not limited in the embodiments of the present application.

[0074] In order to better implement the embodiment of the present application, in one embodiment of the present application, the target opening degree of the target valve is determined according to the current temperature, the valve opening time and the valve opening change time, including:

[0075] If the current temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, and the valve opening time is less than the valve opening change time, the target opening degree is determined according to the first fitting coefficient, the second fitting coefficient and the valve opening time; if the current temperature is greater than the third temperature threshold and less than or equal to the second temperature threshold, and the valve opening time is greater than or equal to the valve opening change time, the target opening degree is determined to be the first opening degree; if the current temperature is greater than or equal to the third temperature threshold, and the valve opening time is greater than or equal to the valve opening change time, the target opening degree is determined according to the third fitting coefficient, the fourth fitting coefficient and the valve opening time.

[0076] The above embodiment provides a solution for using valve opening time for alarm. The embodiment of the present application also provides a solution for applying valve opening time to specific valve opening degree control.

[0077] If the current temperature is less than the first temperature threshold, the target valve is in the closed stage.

[0078] In addition, according to the first fitting coefficient, the second fitting coefficient and the valve opening time, the target opening degree can be determined by the following formula (1):

[0079] T1≤T≤T2, L=a*x+b……(1)

[0080] In formula (1), T1 is the first temperature threshold, T2 is the second temperature threshold, a is the first fitting coefficient, b is the second fitting coefficient, L is the valve opening degree, and x is the valve opening time. The coefficient a and the coefficient b can be set according to the actual situation, and the embodiment of the present application does not limit them.

[0081] Alternatively, a and b can be solved in the following way, for example:

[0082] If T = T1, L = 0, the valve has not yet opened, that is, x = 0, L = 0;

[0083] If T reaches T2, L = maximum opening degree, and the valve opening time is x1, for example 5 minutes; that is, the fitting equation L = a*x+b, when x = 0, L = 0, when x = valve opening change time, L = maximum opening degree, substitute into the equation, and get two relations, 0 = a*0+b, and maximum opening degree = a*x1+b, and then obtain a and b.

[0084] At the same time, in the embodiment of the present application, the first opening degree may be the maximum opening degree of the target valve.

[0085] It should also be noted that, according to the third fitting coefficient, the fourth fitting coefficient and the valve opening time, the target opening degree can be determined by formula (2):

[0086] T3+ΔT≥T, L=c*x+d……(2)

[0087] In formula (2), ΔT is the temperature error, which can be set according to the actual situation, T3 is the third temperature threshold, L is the opening degree of the target valve, c is the third fitting coefficient, d is the fourth fitting coefficient, and x is the valve opening time. Among them, coefficient a and coefficient b can be set according to the actual situation, and the embodiment of the present application does not limit them.

[0088] Alternatively, the time point when T decreases to T3+ΔT minus the time point when T reaches T1 is obtained by subtracting the time point when T reaches T1 from the time point when T decreases to T2+ΔT, and the valve opening time x2 (including the time when L increases from 0 to the maximum opening and is maintained at the maximum opening) is obtained, at this time L=maximum opening; when T decreases to T3+ΔT, the valve starts to change from L=maximum opening to L=0, and the time elapsed is x1, that is, when L=0 at this time, the valve opening time is x2+x1; that is, the fitting equation L=c*x+d satisfies L=maximum opening, x=x2, L=0, x=x2+x1, and substituting into the equation, two relationships are obtained: maximum opening=c*x2+d and 0=c*(x2+x1)+d, and the sum of c and d is calculated.

[0089] In order to better implement the embodiment of the present application, in one embodiment of the present application, determining the valve opening change time corresponding to the target valve according to the consumed time includes:

[0090] Obtain a fifth fitting coefficient and a sixth fitting coefficient; and determine a valve opening change time corresponding to the target valve according to the fifth fitting coefficient, the sixth fitting coefficient and the consumed time.

[0091] In the embodiment of the present application, according to the fifth fitting coefficient, the sixth fitting coefficient and the consumed time, the valve opening change time corresponding to the target valve can be determined by referring to formula (3):

[0092] Valve opening change time = m*t1+n……(3)

[0093] In Formula 3, m is the fifth fitting coefficient, n is the sixth fitting coefficient, and t1 is the consumed time. The fifth fitting coefficient and the sixth fitting coefficient can be set according to actual conditions, and the embodiment of the present application does not limit them.

[0094] In order to better implement the embodiment of the present application, in one embodiment of the present application, the opening and closing of the target valve is controlled according to the current temperature and the valve opening change time, including:

[0095] The current temperature is controlled so that after the valve opening change time, the current temperature reaches the second temperature threshold; the opening and closing of the target valve is controlled so that after the valve opening change time, the target opening and closing degree of the target valve reaches the maximum opening and closing degree.

[0096] In the above embodiment, a solution is provided for setting the valve opening change time as the overall working time of the valve. In the embodiment of the present application, the valve opening change time can be set as the time required for the opening degree of the target valve to reach the maximum opening degree.

[0097] The method for obtaining the valve opening change time is the same as that in the above embodiment and will not be described in detail here.

[0098] After obtaining the valve opening change time, the maximum opening and closing degree of the valve can be obtained. At this time, the minimum required opening and closing change rate can be known based on the valve opening change time and the maximum opening and closing degree. If the current temperature is greater than the first temperature threshold and less than the second temperature threshold, it can be calculated based on the current opening and closing degree and the opening and closing change rate whether the valve can reach the maximum degree after the valve opening change time. If not, the opening and closing degree can be appropriately increased, wherein a certain error can be allowed in the embodiment of the present application.

[0099] Similarly, the temperature control method can be similar to the valve control method. Specifically, the temperature can be monitored. If the temperature does not meet the requirements, the heating power of the equipment can be increased.

[0100] In order to better implement the embodiment of the present application, in one embodiment of the present application, controlling the current temperature includes:

[0101] According to the valve opening time, the temperature change rate of the current temperature is determined; according to the temperature change rate, the working power of the target device is adjusted to control the current temperature.

[0102] The embodiment of the present application also provides a solution for controlling the temperature. Specifically, in the embodiment of the present application, the rate of change of the current temperature can be determined by the valve opening time. For example, if the valve opening time is 5 minutes, the temperature change rate within 5 minutes is calculated. If the temperature cannot meet the temperature requirement after the valve is opened and closed to the maximum opening degree according to the temperature change rate, the working power of the equipment can be increased.

[0103] In order to better implement the dryer control method in the embodiment of the present application, in addition to the dryer control method, the embodiment of the present application also provides a dryer control device, the method is applied to a target device with a drying function, the target device includes a heat exchanger, a target valve for controlling the flow of condensing water, and the target valve is connected to the heat exchanger through a pipeline, such as Figure 3 As shown, the device 300 includes:

[0104] The acquisition module 301 is used to acquire the current temperature of the heat exchanger if the target device is in working state;

[0105] A determination module 302, for determining an elapsed time to reach a first temperature threshold if the current temperature is greater than or equal to a first temperature threshold;

[0106] The control module 303 is used to control the opening and closing of the target valve according to the current temperature and the elapsed time, so as to control the flow rate of the condensing water flowing into the heat exchanger.

[0107] The clothes dryer control device provided by the present application can use water as a refrigerant to replace conventional chemical refrigerants for easy replenishment. At the same time, when the device is working, the acquisition module 301 can first obtain the current temperature of the heat exchanger and the determination module 302 can determine the time elapsed when the current temperature reaches the first temperature threshold according to the current temperature. Then, the control module 303 can control the flow of condensation water according to the current temperature and the elapsed time to avoid continuous injection of cold water for condensation and prevent water waste.

[0116] If the current temperature is greater than the third temperature threshold and less than or equal to the second temperature threshold, and the valve opening time is greater than or equal to the valve opening change time, the target opening degree is determined to be the first opening degree;

[0117] If the current temperature is greater than or equal to the third temperature threshold, and the valve opening time is greater than or equal to the valve opening change time, the target opening degree is determined according to the third fitting coefficient, the fourth fitting coefficient and the valve opening time.
