Description

Technical Field

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

[0002] With the improvement of people's living standards, various types of smart home products are emerging. Clothes drying racks (i.e. Airer) are a necessity for home life. They can provide suitable space for drying clothes and improve the efficiency of drying clothes. Generally speaking, clothes drying racks can be divided into fixed clothes drying racks and liftable clothes drying racks. Among them, liftable clothes drying racks can adjust the height of the clothes drying rack according to actual needs, so as to facilitate users to hang and take clothes. According to the different lifting methods, liftable clothes drying racks can be divided into hand-cranked clothes drying racks and electric clothes drying racks. Among them, electric clothes drying racks have a high degree of automation and a simple and fashionable appearance, which has been favored by more and more users.

[0003] In order to improve the drying efficiency, a clothes drying rack with drying function has been developed in the prior art. During the drying process, it is necessary to temporarily close the clothes drying space (such as a balcony, etc.) to improve the drying efficiency. However, as the moisture contained in the clothes is evaporated by heat, water vapor will accumulate in the clothes drying space, resulting in a significant increase in the humidity in the clothes drying space, and the user will feel uncomfortable if he stays in the clothes drying space. For this reason, a smart clothes drying rack with dehumidification function has been developed in the prior art. For example, Chinese utility model patent CN212771578U discloses a dehumidifying clothes drying rack, which includes a main unit, a lifting unit, a connector for connecting the main unit and the lifting unit, a refrigeration device and a drive control module, the drive control module drives the connector to control the lifting unit to rise or fall, and the refrigeration device is arranged on the lifting unit. The setting of the refrigeration device can make the water vapor in the clothes drying space condense into liquid water when it is cooled, which can not only reduce the humidity in the clothes drying space and improve the user experience, but also ensure that the hot air delivered is dry, thereby improving the drying efficiency.

[0004] However, the output power of existing smart clothes drying racks is mostly fixed, resulting in low drying efficiency and long drying time under low temperature conditions such as winter, while under high temperature conditions such as summer, the drying components of the smart clothes drying racks are at risk of shutting down due to excessive temperature.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0006] In order to solve or improve to a certain extent the technical problem that the drying system of the clothes drying rack in the prior art cannot be adjusted according to the actual needs of the clothes drying environment, the present invention provides a control method for the clothes drying rack. The clothes drying rack includes a drying system, and the control method includes: obtaining the temperature T and humidity RH of the clothes drying environment; determining the temperature and humidity coupling parameter M according to the temperature T and the humidity RH; comparing the temperature and humidity coupling parameter M with a preset temperature and humidity coupling parameter threshold; and determining the initial output power of the drying system based on the comparison result.

[0007] In the control method for clothes drying rack of the present invention, the temperature T and humidity RH of the clothes drying environment are first obtained. Then, the temperature and humidity coupling parameter M is determined according to the measured temperature T and humidity RH of the clothes drying environment. It should be pointed out that the "temperature and humidity coupling parameter M" is a parameter value preset by the present invention according to the temperature T and humidity RH of the clothes drying environment, which can be used to characterize the influence of the temperature T and humidity RH of the clothes drying environment on the output power of the drying system. Then, the temperature and humidity coupling parameter M is compared with the preset temperature and humidity coupling parameter threshold. Finally, the initial output power of the drying system in the clothes drying rack is determined based on the comparison result. Through the above settings, the control method for clothes drying rack of the present invention can flexibly select the initial output power according to the actual temperature and humidity conditions of the clothes drying environment, which not only avoids the drying efficiency being too low under low temperature conditions, but also avoids the phenomenon of the drying system shutting down due to excessively high temperature under high temperature conditions, thereby ensuring the smooth operation of the drying system and improving the user experience.

[0008] In the preferred technical solution of the control method for the clothes drying rack, the temperature and humidity coupling parameter M is calculated based on the following formula: M = aT-bRH+c, where a is the temperature change factor, b is the humidity change factor, and c is the correction constant. The specific value of the temperature and humidity coupling parameter M can be easily calculated through the above formula. It should be pointed out that, for the convenience of calculation, the temperature and humidity coupling parameter M is a parameter without unit dimension, only with numerical value.

[0009] In the preferred technical solution of the control method for the clothes drying rack, the preset temperature and humidity coupling parameter thresholds include a first threshold M1 and a second threshold M2, the first threshold M1 is less than the second threshold M2; the initial output power includes a first preset output power, a second preset output power and a third preset output power, the second preset output power is greater than the first preset output power and less than the third preset output power; and when the temperature and humidity coupling parameter M is less than or equal to the first threshold M1, the drying system uses the third preset output power as the initial output power; when the temperature and humidity coupling parameter M is greater than the first threshold M1 and less than or equal to the second threshold M2, the drying system uses the second preset output power as the initial output power; when the temperature and humidity coupling parameter M is greater than the second threshold M2, the drying system uses the first preset output power as the initial output power. Through the above settings, the initial output power can meet the actual needs under low temperature, medium temperature and high temperature conditions.

[0010] In the preferred technical solution of the control method for the clothes drying rack, the first threshold M1 has a value range of 35-40, and the second threshold M2 has a value range of 120-125; and / or the first preset output power has a value range of 500W-800W, the second preset output power has a value range of 801W-1000W, and the third preset output power has a value range of 1001W-1200W. Through the above settings, the first threshold M1, the second threshold M2, the first preset output power, the second preset output power and the third preset output power can have a moderate value range.

[0011] In the preferred technical solution of the control method for the clothes drying rack, the control method further includes: re-obtaining the humidity RH of the clothes drying environment after a preset time period; comparing the humidity RH with a preset humidity range; and adjusting the output power of the drying system based on the comparison result. Through the above settings, the output power of the drying system can be adjusted according to the humidity RH of the clothes drying environment to better meet actual needs. In addition, re-obtaining the humidity of the clothes drying environment after a preset time period can reserve sufficient reaction time to ensure the accuracy of the measurement.

[0012] In the preferred technical solution of the control method for the clothes drying rack, the preset humidity interval includes a plurality of continuous humidity interval units, and the output power decreases in sequence by a preset output power difference as the humidity interval units decrease. By setting the output power of the drying system to decrease in sequence by a preset output power difference as the humidity interval units decrease, not only can the drying system meet the drying needs, but also the energy consumption can be appropriately reduced, thereby achieving the effect of energy saving and emission reduction.

[0013] In the preferred technical scheme of the above-mentioned control method for clothes drying rack, the multiple continuous humidity interval units include: a first humidity interval, which is greater than 80%; a second humidity interval, which is greater than 70% and less than or equal to 80%; a third humidity interval, which is greater than 60% and less than or equal to 70%; a fourth humidity interval, which is greater than 50% and less than or equal to 60%; a fifth humidity interval, which is greater than 40% and less than or equal to 50%; a sixth humidity interval, which is greater than 30% and less than or equal to 40%; a seventh humidity interval, which is less than or equal to 30%; and the preset output power difference value ranges from 10W to 20W.

[0014] In the preferred technical solution of the control method for the clothes drying rack, when the humidity RH falls into the first humidity interval, the drying system is kept running at the initial output power. When the humidity RH falls into the first humidity interval, it means that the humidity RH of the clothes drying environment is still relatively high, and the drying system is kept running at the initial output power to ensure the drying efficiency.

[0015] In the preferred technical solution of the control method for the clothes drying rack, the clothes drying environment is a closed space isolated from the external environment. The clothes drying environment is set as a closed space isolated from the external environment, so that the heat generated by the drying system can be accumulated in the clothes drying space, preventing heat loss and ensuring drying efficiency.

[0016] In order to solve or improve to a certain extent the technical problem that the drying system of the clothes drying rack in the prior art cannot be adjusted according to the actual needs of the clothes drying environment, the present invention provides a clothes drying rack. The control method for the clothes drying rack described in any one of the above items is executed in the clothes drying rack. By adopting the control method for the clothes drying rack described in any one of the above items, the clothes drying rack of the present invention can adjust the initial output power according to the temperature and humidity changes of the clothes drying environment, which not only avoids the drying efficiency being too low under low temperature conditions, but also avoids the phenomenon of the drying system shutting down due to excessive temperature under high temperature conditions, thereby ensuring the smooth operation of the drying system and improving the user experience.

[0027] In order to solve or improve to a certain extent the technical problem that the drying system of the clothes drying rack in the prior art cannot be adjusted according to the actual needs of the clothes drying environment, the present invention provides a control method for the clothes drying rack 1. The clothes drying rack 1 includes a drying system 20, and the control method includes: obtaining the temperature T and humidity RH of the clothes drying environment (step S1); determining the temperature and humidity coupling parameter M according to the temperature T and the humidity RH (step S2); comparing the temperature and humidity coupling parameter M with a preset temperature and humidity coupling parameter threshold (step S3); and determining the initial output power of the drying system 20 based on the comparison result (step S4).

[0028] Figure 1 2 is a schematic structural diagram of an embodiment of a clothes drying rack of the present invention; Figure 2 Schematic diagram of the structure of an embodiment of the drying system of the clothes drying machine of the present invention. Figure 1-Figure 2As shown, in one or more embodiments, the clothes drying rack 1 of the present invention includes components such as a main unit 10, a drying system 20, a lifting rod 30 and a clothes drying rod 40. Among them, the main unit 10 has a shell 11 that is roughly rectangular. The shell 11 can be made of suitable metal materials such as aluminum alloy and stainless steel, so that it has good mechanical strength. The interior of the shell 11 forms a storage space for installing the drying system 20. In one or more embodiments, a partition plate 12 extending roughly in the left and right directions is provided in the middle of the shell 11 to divide the storage space into two upper and lower spaces. In one or more embodiments, a temperature and humidity sensor (not shown in the figure) for detecting the temperature and humidity of the clothes drying environment is also provided in the shell 11. The arrangement position and number of the temperature and humidity sensors can be adjusted according to actual conditions.

[0029] Continue to see Figure 1 and Figure 2 In one or more embodiments, the drying system 20 is a heat pump system. The heat pump system includes a compressor 21, a condenser 22, a throttling device 23 and an evaporator 24 connected in sequence through a refrigerant pipeline to form a refrigeration circuit that allows a refrigerant (such as R34A, etc.) to circulate therein. The setting of the heat pump system can make the drying system 20 have a higher drying efficiency and reduce energy consumption. Alternatively, the drying system 20 can also adopt an electric heating system, a far-infrared heating system or other suitable drying systems.

[0030] In one or more embodiments, the compressor 21 is a fixed-frequency compressor to reduce component costs. Alternatively, the compressor 21 may also be a variable-frequency compressor so that the operating frequency of the compressor 21 can be adjusted according to actual needs. The compressor 21 may be, but is not limited to, a screw compressor, a turbine compressor, a rotary compressor, etc. In one or more embodiments, the condenser 22 is a finned coil heat exchanger. Alternatively, the condenser 22 may also be a plate heat exchanger or other suitable heat exchanger. The throttling device 23 may be, but is not limited to, a capillary tube, an electronic expansion valve, etc. In one or more embodiments, the evaporator 24 is a finned coil heat exchanger. Alternatively, the evaporator 24 may also be a plate heat exchanger or other suitable heat exchanger. See Figure 2In one or more embodiments, the compressor 21 and the throttling device 23 are arranged at the upper part of the partition plate 12, while the condenser 22 and the evaporator 23 are arranged at the lower part of the partition plate 12. In this way, the compressor 21 and the throttling device 23 can have a stable working environment, and a flow channel allowing the circulation of air can be formed at the lower part of the partition plate 12, so that the air can flow through the evaporator 23 and the condenser 22 in sequence to achieve heat exchange. A supply air fan 25 is provided at a position close to the condenser 22, and a corresponding air supply port (not shown in the figure) is provided at the lower part of the shell 11, so as to transport the dry air generated by flowing through the condenser 22 from the air supply port to the clothes drying environment. Correspondingly, a circulation fan 26 is provided at a position close to the evaporator 24, and a corresponding return air port is provided at the lower part of the shell 11, so that the humid air in the clothes drying environment can enter the shell 11 from the return air port, and be pre-cooled and condensed into liquid water when flowing through the surface of the evaporator 24. This can not only reduce the humidity in the clothes drying environment to prevent users from feeling uncomfortable due to excessive humidity, but also keep the drying air dry and improve the drying efficiency. In one or more embodiments, a water collecting tank (not shown in the figure) is further provided at the bottom of the evaporator 24 to collect condensed water flowing down from the surface of the evaporator 24. A drain pipe (not shown in the figure) can also be provided on the water collecting tank to drain the condensed water in the water collecting tank in time.

[0031] Continue to see Figure 1 In one or more embodiments, lifting rods 30 are provided at the lower part of the main unit 10, respectively on the left and right sides. One end of each lifting rod 30 away from the main unit 10 is fixedly connected to the clothes drying rod 40. The setting of the lifting rod 30 can conveniently adjust the height of the clothes drying rod 40, which is convenient for users to hang and take clothes 2. The lifting rod 30 can rise or fall under the control of a motor (not shown in the figure), so as to achieve the height adjustment of the clothes drying rod 40. A plurality of clothes drying holes (not shown in the figure) spaced apart from each other can be provided on the clothes drying rod 40, so that a clothes hanger with clothes 2 hung thereon can be conveniently fixed in the clothes drying holes.

[0032] Next, combine Figure 3-Figure 4 The control method of the present invention for the clothes drying rack 1 is described in detail. It should be noted that the control method of the present invention can be implemented in the clothes drying rack 1 described in any of the above embodiments, and can also be implemented in other suitable clothes drying racks.

[0033] Figure 3 FIG. 1 is a flow chart of a control method for a clothes drying machine according to the present invention. Figure 3As shown, in one or more embodiments, when the control method of the present invention for the clothes drying rack 1 starts, step S1 is first executed, that is, the temperature T and humidity RH of the clothes drying environment are obtained. The temperature T and humidity RH of the clothes drying environment can be measured by a temperature and humidity sensor arranged on the housing 11 of the clothes drying rack 1. Next, step S2 is executed to determine the temperature and humidity coupling parameter M according to the temperature T and humidity RH. The temperature and humidity coupling parameter M is a parameter value preset by the present invention according to the temperature T and humidity RH of the clothes drying environment, which can be used to characterize the influence of the temperature T and humidity RH of the clothes drying environment on the output power of the drying system. Then, the control method executes step S3 to compare the temperature and humidity coupling parameter M with the preset temperature and humidity coupling parameter threshold; finally, the control method executes step S4 to determine the initial output power of the drying system 20 based on the comparison result. Through the above-mentioned settings, the control method for the clothes drying rack 1 of the present invention can flexibly adjust the initial output power according to the temperature and humidity changes in the clothes drying environment, which not only avoids the low drying efficiency under low temperature conditions, but also avoids the shutdown of the drying system 20 due to excessive temperature under high temperature conditions, thereby ensuring the smooth operation of the drying system 20 and improving the user experience.

[0034] Figure 4 FIG. 1 is a flow chart of a first embodiment of a control method for a clothes drying rack according to the present invention. Figure 4 As shown, in one or more embodiments, when the control method for the clothes drying rack 1 of the present invention starts, step S10 is first performed, that is, the temperature T and humidity RH of the clothes drying environment are obtained. In one or more embodiments, the clothes drying environment is a closed space isolated from the external environment, such as a closed balcony or other suitable space, to prevent heat loss and ensure the drying efficiency of the drying system 20. Then, the control method proceeds to step S20, that is, the temperature and humidity coupling parameter M is calculated according to the formula M=aT-bRH+c. Wherein, a is the temperature change factor, b is the humidity change factor, and c is the correction common sense. a increases with the increase of temperature T, and b increases with the increase of humidity RH. In one or more embodiments, when the temperature T is 10°C and the humidity RH is 50%, the value of a is 2, the value of b is 20, and the value of c is 5, then the value of the temperature and humidity coupling parameter M is M=2×10-20×0.5+5=15. In order to simplify the calculation, the temperature and humidity coupling parameter M has no unit dimension, only the numerical value. In one or more embodiments, when the temperature T is 30° C. and the humidity RH is 60%, the value of a is 6, the value of b is 50, and the value of c is 5, then the value of the temperature and humidity coupling parameter M is M=6×30-50×0.6+5=155. It should be noted that the specific values ​​of a, b and c can be obtained based on experiments or experience.

[0035] Continue to see Figure 4, when step S20 is completed, the control method executes step S31, that is, judging whether the temperature and humidity coupling parameter M is less than or equal to the first threshold M1. In one or more embodiments, the value range of the first threshold M1 is 35-40. When the judgment result is yes, it means that the temperature T of the clothes drying environment is low or the humidity RH is high at this time, then the control method executes step S41, and controls the drying system 20 to use the third preset output power as the initial output power. In one or more embodiments, the value range of the third preset output power is 1001W-1200W to ensure the drying efficiency. Alternatively, the third preset output power can also be set to other suitable power values. After executing step S31, when the judgment result is no, continue to execute step S32, that is, judging whether the temperature and humidity coupling parameter M is greater than the second threshold M2. In one or more embodiments, the value range of the second threshold M2 is 120-125. When the judgment result is yes, it means that the temperature T of the clothes drying environment is high or the humidity RH is low at this time, then the control method executes step S43, and controls the drying system 20 to use the first preset output power as the initial output power. Wherein, the first preset output power is less than the third preset output power. In one or more embodiments, the value range of the first preset output power is 500W-800W to avoid the shutdown of the drying system 20 due to high temperature. Alternatively, the first preset output power can also be set to other suitable power values. After executing step S32, when the judgment result is no, it means that the temperature T and humidity RH of the clothes drying environment are moderate at this time, then the control method executes step S42, that is, controls the drying system 20 to use the second preset output power as the initial output power. Wherein, the second preset output power is greater than the first preset output power and less than the third preset output power. In one or more embodiments, the value range of the second preset output power is 801W-1000W. Alternatively, the second preset output power can also be set to other suitable power values.

[0036] Figure 5 2 is a flow chart of a second embodiment of the control method for clothes drying racks of the present invention. Figure 5 As shown, in one or more embodiments, the control method for the clothes drying rack 1 of the present invention further executes step S5, that is, after a preset time period, the humidity RH of the clothes drying environment is re-acquired. In one or more embodiments, the preset time period is 10 minutes. Alternatively, the preset time period can also be set to other suitable time periods longer or shorter than 10 minutes. Then, the control method proceeds to step S6, that is, comparing the humidity RH with the preset humidity interval. Then, based on the comparison result, the output power of the drying system 20 is adjusted (i.e., step S7).

[0037] In one or more embodiments, the preset humidity interval includes a plurality of continuous humidity interval units, and the output power of the drying system 20 decreases with the decrease of the humidity interval unit in turn by the preset output power difference. In one or more embodiments, the plurality of continuous humidity interval units include a first humidity interval, which is greater than 80%; a second humidity interval, which is greater than 70% and less than or equal to 80%; a third humidity interval, which is greater than 60% and less than or equal to 70%; a fourth humidity interval, which is greater than 50% and less than or equal to 60%; a fifth humidity interval, which is greater than 40% and less than or equal to 50%; a sixth humidity interval, which is greater than 30% and less than or equal to 40%; and a seventh humidity interval, which is less than or equal to 30%. Alternatively, the plurality of continuous humidity interval units may also be set to other suitable humidity intervals more or less than 7. In one or more embodiments, the preset output power difference value ranges from 10W to 20W, so that it has a moderate numerical range. Alternatively, the preset output power difference value may also be adjusted according to actual needs. In one or more embodiments, when the humidity RH of the clothes drying environment falls into the first humidity interval, the drying system 20 is kept running at the initial output power.

[0038] For example, in one or more embodiments, the initial output power of the drying system 20 is a first preset output power, the value of the first preset output power is 600W, and the value of the preset output power difference is 20W. The drying system 2 runs for a preset time period (e.g., 10 minutes) to dry the clothes 2 in the clothes drying environment. At this time, if the humidity RH of the clothes drying environment falls into the first humidity interval, that is, greater than 80%, it means that the humidity in the clothes drying environment is still high and the heat demand is high, then the drying system 20 is kept running at the initial output power to ensure the drying efficiency. When the humidity RH of the clothes drying environment falls into the second humidity interval, the drying system 20 is controlled to run at the initial output power minus the preset output power difference (i.e., 600W minus 20W equals 580W). Correspondingly, when the humidity RH of the clothes-drying environment falls into the third humidity interval, the drying system 20 is controlled to operate at an output power of 560W; when the humidity RH of the clothes-drying environment falls into the fourth humidity interval, the drying system 20 is controlled to operate at an output power of 540W; when the humidity RH of the clothes-drying environment falls into the fifth humidity interval, the drying system 20 is controlled to operate at an output power of 520W; when the humidity RH of the clothes-drying environment falls into the sixth humidity interval, the drying system 20 is controlled to operate at an output power of 500W; when the humidity RH of the clothes-drying environment falls into the seventh humidity interval, the drying system 20 is controlled to operate at an output power of 480W, until the entire drying process is completed. In one or more embodiments, when the humidity RH of the clothes-drying environment is lower than a preset humidity value (e.g., 10%, 15%, 20%, etc.), it is determined that the clothes 2 have been dried, and the drying system 20 is controlled to shut down.

[0039] It should be noted that the parts not mentioned in the second embodiment may be configured the same as those in the first embodiment and will not be described in detail here.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
