Description

Technical Field

[0001] This invention belongs to the field of clothes dryers, and particularly relates to a clothes dryer control method, device, clothes dryer and medium. Background Technology

[0002] As living standards continue to improve, people's demands for quality of life are also increasing, and this demand is particularly evident in household appliances. Taking dryers as an example, current heat pump dryers use a condenser in the heat pump system to heat air and send it into the drying drum containing clothes. The humid air that has drawn moisture from the clothes is sent back to the evaporator for dehumidification. The dehumidified air is then heated again by the condenser and sent into the drying drum.

[0003] However, in practice, it has been found that this heat pump dryer mainly consists of a compressor, condenser, and evaporator. During the drying process, the compressor generates heat to dry the clothes. Although this type of heat pump dryer has the advantage of energy saving, it limits the drying speed. Summary of the Invention

[0004] The present invention aims to solve the technical problem of limited drying speed in heat pump dryers in the prior art, and provides a dryer control method, device, dryer and medium.

[0005] In a first aspect, embodiments of the present invention provide a dryer control method, applied in a dryer, the dryer including a heat exchanger, a fan, an air inlet valve, and a heater, the air inlet valve being disposed between the heat exchanger and the fan, the method comprising:

[0006] After the dryer has been running for a preset time, the temperature parameters of the dryer are monitored. The temperature parameters are used to characterize the temperature of the target components that make up the dryer.

[0007] Based on the monitored temperature parameters, the air intake valve and / or heater in the dryer are controlled accordingly.

[0008] In this embodiment of the invention, after the dryer has been running for a preset time, the air intake valve and / or heater in the dryer are controlled accordingly based on the monitored temperature data. This allows for rapid drying, improving the intelligence and convenience of the dryer's control and enhancing the user experience. Furthermore, it solves the technical problems of existing heat pump dryers, such as limited drying speed, single functional modes, and lack of support for multiple operating modes.

[0009] In some implementations, before performing corresponding drying control on the air intake valve and / or heater in the dryer based on the monitored temperature parameters, the method further includes: determining the operating mode of the dryer; the step of performing corresponding drying control on the air intake valve and / or heater in the dryer based on the monitored temperature parameters includes: performing corresponding drying control on the air intake valve and / or heater in the dryer under the operating mode based on the monitored temperature parameters.

[0010] In this embodiment of the invention, after the dryer has been running for a preset time, the air intake valve and / or heater in the dryer are controlled according to the monitored temperature data and the various operating modes it supports. This allows for rapid drying, improving the intelligence and convenience of the dryer's control and enhancing the user experience. Furthermore, it solves the technical problems of existing heat pump dryers, such as limited drying speed, limited functional modes, and lack of support for multiple operating modes.

[0011] In some implementations, the operating mode is a preset first mode, and the step of controlling the air intake valve and / or heater in the dryer according to the monitored temperature parameters in the operating mode includes:

[0012] The following steps are repeated in the preset first mode until the air humidity inside the drying drum of the dryer reaches the preset humidity:

[0013] When the temperature parameters of the dryer are within the first range, the air inlet valve is opened and the heater continues to heat, so that the temperature parameters of the dryer continue to rise.

[0014] When the temperature parameter of the dryer is within the second range, the heater is stopped to reduce the temperature parameter of the dryer.

[0015] Wherein, the upper limit threshold of the first range is less than or equal to the lower limit threshold of the second range.

[0016] In this embodiment of the invention, under the preset first mode, the invention can safely control the drying process by cyclically controlling the on / off state of the air intake valve and / or heater according to real-time temperature parameters, which is beneficial to improving the safety and convenience of drying control.

[0017] In some implementations, the operating mode is a preset second mode, and the step of controlling the air intake valve and / or heater in the dryer according to the monitored temperature parameters in the operating mode includes:

[0018] The following steps are repeated in the preset second mode until the air humidity inside the drying drum of the dryer reaches the preset humidity:

[0019] When the temperature parameter of the dryer is within the third range, the heater stops heating and the air inlet valve remains closed, and the temperature parameter of the dryer continues to rise;

[0020] When the temperature parameter of the dryer is within the fourth range, the air inlet valve is opened to reduce the temperature parameter of the dryer.

[0021] Wherein, the upper limit threshold of the third range is less than or equal to the lower limit threshold of the fourth range.

[0022] In this embodiment of the invention, under the preset second mode, the invention can also safely control the drying process by cyclically controlling the on / off state of the air intake valve and / or heater based on real-time temperature parameters, which is beneficial to improving the safety and convenience of drying control.

[0023] In some implementations, the method further includes:

[0024] After detecting that the air humidity inside the drying drum of the dryer has reached the preset humidity, the compressor in the dryer stops running and the air intake valve is closed.

[0025] In this embodiment of the invention, the compressor can be stopped and the valve closed when the drying process is finished, thus intelligently realizing convenient drying control and improving the user experience.

[0026] In some implementations, the temperature parameters of the dryer include: the air temperature inside the drying drum of the dryer, or the exhaust temperature of the compressor in the dryer.

[0027] In some implementations, determining the operating mode of the dryer includes:

[0028] Receive user interaction instructions and parse the user interaction instructions to obtain the working mode of the dryer.

[0029] In this embodiment of the invention, user interaction commands can be parsed to accurately obtain the working mode that the user wants the dryer to enter, which helps to improve the accuracy of subsequent drying control.

[0030] Secondly, embodiments of the present invention provide a clothes dryer, comprising: a compressor, a first heat exchanger, a second heat exchanger, a fan, a heater, a drying drum, an air inlet valve, and an exhaust port opened on the drying drum, wherein:

[0031] The compressor, first heat exchanger, fan, heater, drying drum and second heat exchanger are connected in sequence. The air inlet valve is located between the first heat exchanger and the fan to introduce air and speed up the drying efficiency of the dryer. The air introduced by the air inlet valve is heated by the heater and then sent into the drying drum to dry the clothes.

[0032] The exhaust port is used to discharge the humid air carrying heat generated after the clothes are dried in the drying drum, so as to reduce the temperature parameters of the target components in the dryer.

[0033] This invention adds an air inlet valve and an exhaust port on the drying drum to the dryer. By controlling the opening and closing of the air inlet valve, the dryer can achieve rapid drying, which helps to improve the drying speed and efficiency of the dryer and enhance the user experience.

[0034] Thirdly, embodiments of the present invention provide a dryer control device, comprising:

[0035] The data acquisition module is used to monitor the temperature parameters of the dryer after the dryer has been running for a preset time. The temperature parameters are used to characterize the temperature of the target components that make up the dryer.

[0036] The control module is used to perform corresponding drying control on the air intake valve and / or heater in the dryer according to the monitored temperature parameters.

[0037] In this embodiment of the invention, after the dryer has been running for a preset time, the air intake valve and / or heater in the dryer are controlled accordingly based on the monitored temperature data. This allows for rapid drying, improving the intelligence and convenience of the dryer's control and enhancing the user experience. Furthermore, it solves the technical problems of limited drying speed in existing heat pump dryers.

[0048] In view of the technical problem of limited drying speed in existing heat pump dryers, embodiments of the present invention provide a dryer control method, device, dryer and medium. After the dryer has been running for a preset time, the temperature parameters of the dryer are monitored, and the air intake valve and / or heater in the dryer are controlled accordingly based on the monitored temperature parameters to achieve rapid drying, which helps to improve the drying speed and efficiency of the dryer and enhance the user experience.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0050] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0051] The dryer and dryer control method provided in this specification will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0052] Please see Figure 1 This is a structural diagram of a heat pump dryer provided by existing technology. For example... Figure 1 The heat pump dryer shown includes: a compressor 101, a cooling fan 102, a condenser 103, an evaporator 104, a fan 105, a heater 106, a drying drum 107, and an air duct 1000. The cooling fan 102 is used to dissipate heat and cool the compressor 101. The arrows in the diagram indicate the direction of airflow; air flows in the air duct 1000 to dehumidify and dry the clothes in the drying drum.

[0053] In practical applications, heat pump dryers require two circulation stages. First, air circulation: The impeller of the cooling fan 102 provides power, blowing high-temperature, low-humidity air into the drying drum 107. This air becomes medium-temperature, high-humidity air, then passes through a filter (not shown) to remove lint and other debris. After passing through the evaporator 104 and condenser 103 for cooling and dehumidification, it becomes high-temperature, low-humidity air again and flows back into the impeller. Second, refrigeration circulation: High-temperature refrigerant gas from the compressor 101 is discharged into the condenser 103, where it exchanges heat with low-temperature, low-humidity air. As the air temperature rises, the refrigerant flows into the evaporator 104, where it absorbs / recovers heat from the air and simultaneously cools the high-temperature, high-humidity air, causing the moisture to condense and be discharged. The refrigerant then flows back into the compressor 101. These two stages continuously cycle, ultimately removing moisture from the clothes and achieving the drying function / effect of the dryer.

[0054] Understandably, the operating control logic of a heat pump dryer is as follows: After the heat pump dryer is started, the motor (not shown) drives the fan 105 and the drying drum 107 (also known as a roller) to rotate. After a preset time G1 (e.g., 1 minute), the compressor 101 starts, initiating the air circulation and refrigeration cycle for drying. During this process, the exhaust temperature of the compressor 101 and the air temperature inside the drying drum 107 continuously rise. When the exhaust temperature of the compressor 101 reaches the first preset temperature T1, the compressor cooling fan 102 starts to dissipate heat from the compressor 101, maintaining the heat pump system within the safe operating temperature range of the compressor 101. After the compressor cooling fan 102 starts, if the exhaust temperature of the compressor 101 drops to the second preset temperature T2, the compressor cooling fan 102 shuts off and stops operating. The heat pump dryer system detects the air humidity inside the drying drum 107. When the humidity reaches the preset humidity S1 (usually 55%), the compressor 101 stops running, and the fan 105 continues to run for a period of time G2 (e.g., 1 minute) before the heat pump dryer stops.

[0055] It can be seen that the above-mentioned heat pump dryers have the following problems in the drying process: the heat pump system has a slow heating time and a long drying time; the use of a cooling fan to cool the compressor is costly; the system has good sealing performance, but the drying time is long and it does not support multiple working modes, so the functional modes are relatively simple.

[0056] To address the above problems, embodiments of the present invention provide a clothes dryer, a clothes dryer control method, and a device thereof. Please refer to [link / reference]. Figure 2 This is a structural schematic diagram of a clothes dryer provided in an embodiment of the present invention. The clothes dryer can refer to a clothes dryer simply used for drying clothes, a washer-dryer combo that supports both drying and washing, or other devices that support drying, etc., and the present invention does not limit this. Figure 2The dryer shown includes: a heater 100, a compressor 200, a drying drum 300, a first heat exchanger 500 (which may be a condenser in this example), a second heat exchanger 400 (which may be an evaporator in this example), a fan 600, an air inlet valve 700, and an exhaust port 800 on the drying drum 300. Optionally, the air inlet valve 700 is specifically installed on the air inlet 710, and it can be located between the first heat exchanger 500 and the fan 600. The air inlet valve 700 is used to introduce air, thereby accelerating the drying speed and efficiency of the dryer. The air introduced by the air inlet valve 700 is heated by the heater 100 and then sent into the drying drum 300 for drying clothes. The specific working principle is described below. An exhaust valve 810 may also be provided on the exhaust port 800. When the dryer is running, the exhaust valve 810 can be automatically opened so that the exhaust port 800 is in an open state; conversely, when the dryer finishes drying or stops, the exhaust valve 810 can be automatically closed so that the exhaust port 800 is in a closed state, preventing impurities in the air from entering the dryer.

[0057] In practical applications, please refer to Figure 3 The image shows a side view of a clothes dryer from different angles. Figure 3 In this design, the air inlet valve 700 is located on the dryer base, and its air inlet 710 is connected to the fan 600 and the first heat exchanger 500 on the base. The exhaust port 800 is located on the drying drum 300 (also known as the roller), and its exhaust port / exhaust valve 810, which is connected to the air duct of the front support, is connected to the rear of the dryer via a flexible hose, so that the humid air inside the drying drum can be discharged from the rear of the dryer.

[0058] The compressor 200, the first heat exchanger 500, the fan 600, the heater 100, the drying drum 300, and the second heat exchanger 400 are connected sequentially. An air inlet valve 700 (and its air inlet 710) is located between the first heat exchanger 500 and the fan 600 to introduce air and accelerate the drying efficiency of the dryer. Optionally, the dryer also includes an air duct 1000, through which the aforementioned components are connected. Arrows within the air duct 1000 indicate the direction of airflow. Air flows within the air duct 1000 to dehumidify and dry the clothes in the drying drum. The exhaust port 800 is used to discharge the humid air generated after drying clothes in the drying drum 300. This humid air carries heat to reduce the temperature parameters of the target components in the dryer and prevent damage to the dryer.

[0059] In practical applications, the working principle of the dryer is as follows: When the compressor 200 starts, it sends air into the first heat exchanger 500 for heating. Optionally, when the inlet valve 700 is open, additional air introduced through the inlet valve 700 is circulated by the fan 600 and reheated by the heater 100 before being sent into the drying drum 300 to dry the clothes. After drying, the humid air in the drying drum is sent back to the second heat exchanger 400 for dehumidification. The dehumidified air is then sent back into the first heat exchanger 500 for heating, and this process is repeated to circulate air for drying clothes until drying is complete. Optionally, when the exhaust port 800 is open (i.e., the exhaust valve 810 is open), the humid air in the drying drum can also be discharged through the exhaust port 800 to lower the temperature parameters of corresponding components in the dryer, such as the drying drum and compressor, to prevent damage to the dryer.

[0060] Please see Figure 4 This is a flowchart illustrating a dryer control method provided in an embodiment of the present invention. Figure 4 The method shown is applied to Figure 2 The method for using a clothes dryer includes the following implementation steps:

[0061] S401. After the dryer has been running for a preset time, monitor the temperature parameters of the dryer. The temperature parameters are used to characterize the temperature of the target components that make up the dryer.

[0062] The temperature parameters described in this invention refer to temperature parameters used to describe any one or more target components constituting the dryer. These may include, but are not limited to, the exhaust temperature of the compressor, the air temperature inside the drying drum, the heating temperature of the heater, and the condensing temperature of the heat exchanger, specifically the condensing temperature of the condenser. The number of temperature parameters is not limited; there may be one or more.

[0063] To save energy, this invention continuously monitors the temperature parameters of the dryer after it has been running for a preset time, for example, by collecting the temperature parameters of the dryer at preset time intervals.

[0064] In an alternative embodiment, the present invention may further determine the operating mode of the dryer before or after step S401.

[0065] The dryer described in this invention supports multiple operating modes, which can be set according to the user's actual needs. For example, this invention uses the dryer's supported operating modes, including fast drying mode (also known as intelligent fast drying mode) and energy-saving mode (also known as energy-saving and environmentally friendly mode), as examples to illustrate the relevant content, but this does not constitute a limitation.

[0066] In one specific embodiment, the present invention can receive user interaction instructions, which are used to indicate the desired operating mode of the dryer. Accordingly, the present invention can obtain the operating mode of the dryer by parsing the user interaction instructions.

[0067] In another specific embodiment, the present invention can acquire ambient temperature and humidity data and the temperature and humidity data within the dryer. Furthermore, the present invention can analyze the ambient temperature and humidity data and the temperature and humidity data within the dryer to determine the working mode of the dryer. Specifically, the present invention can analyze the magnitude relationship, difference data, or any data among any temperature or humidity data in the ambient temperature and humidity data and the temperature and humidity data within the dryer to determine the corresponding working mode. For example, when the temperature data in the ambient temperature and humidity data is large (e.g., greater than a preset temperature), an energy-saving mode can be selected. When the humidity and temperature data in the ambient temperature and humidity data are small (e.g., less than or equal to a preset temperature), a fast-drying mode of the dryer can be selected.

[0068] S402. Based on the monitored temperature parameters, perform corresponding drying control on the air intake valve and / or heater in the dryer.

[0069] Specifically, the present invention can perform corresponding drying control on the air intake valve and / or heater in the dryer according to the monitored temperature parameters in the working mode.

[0070] In one specific embodiment, the operating mode is a preset first mode, such as a quick-drying mode or other user-defined operating modes. In the preset first mode, the present invention can repeatedly execute the following steps until drying is complete: when the temperature parameter of the dryer is within a first range, the air inlet valve is opened, and the heater continues to heat, causing the temperature parameter of the dryer to continue to rise; when the temperature parameter of the dryer is within a second range, the heater is stopped to lower the temperature parameter of the dryer. Wherein, the upper threshold of the first range is less than or equal to the lower threshold of the second range.

[0071] In another specific embodiment, the operating mode is a preset second mode, such as an energy-saving mode or other user-defined operating modes. In the preset second mode, the present invention can repeatedly execute the following steps until drying is complete: when the temperature parameter of the dryer is within a third range, the heater is stopped, and the air inlet valve remains closed, allowing the temperature parameter of the dryer to continue rising; when the temperature parameter of the dryer is within a fourth range, the air inlet valve is opened to lower the temperature parameter of the dryer. Wherein, the upper limit of the third threshold is less than or equal to the lower limit of the fourth range.

[0072] The first range, second range, third range, and fourth range involved in this invention are all system-defined settings. The first range and the third range, as well as the second range and the fourth range, may be the same or different; this invention does not impose any limitations. The preset first mode and the preset second mode involved in this invention have different drying speeds and efficiencies, with the preset first mode having a faster drying speed or higher efficiency than the preset second mode.

[0073] The method for determining the end of drying according to the present invention can be as follows: when the air humidity inside the drying drum of the dryer reaches a preset humidity, drying can be determined to be finished. Further optionally, after detecting / determining that the air humidity inside the drying drum of the dryer has reached the preset humidity, the present invention can stop the operation of the compressor in the dryer and close the air intake valve.

[0074] To facilitate understanding of the technical solutions provided in the embodiments of the present invention, taking the temperature parameters of the dryer, including the air humidity inside the drying drum of the dryer or the exhaust temperature of the compressor, as examples, several implementation methods of the dryer control method in the embodiments of the present invention are described in the fast drying mode and energy-saving mode of the dryer, respectively, and are not intended to limit the embodiments of the present invention.

[0075] For the first preset mode:

[0076] In this invention, after the dryer is started, the motor drives the fan and the drying drum to rotate, while the heater starts to heat the circulating air. At this time, the air inlet valve is closed. After a preset time (e.g., 1 minute), the compressor starts. Because the heater is running, the temperature inside the drying drum (drum) and the exhaust temperature of the compressor continuously rise. When the temperature inside the drying drum rises to the first range T11 (e.g., around 50-60°C), the air inlet valve opens, and the heater continues to heat. Because heat from the dryer system escapes through the exhaust port after the air inlet valve opens, the temperature inside the drying drum generally remains stable or rises slowly. When the temperature inside the drying drum continues to rise to the second range T12 (e.g., 60-65°C), or the exhaust temperature of the compressor rises to the corresponding preset second range T12 (e.g., a safe temperature range, greater than 90°C), the heater stops heating.

[0077] Furthermore, as the heater stops heating, the temperature inside the drying drum and the compressor's exhaust temperature drop rapidly. When the temperature inside the drying drum (or the compressor's exhaust temperature) drops to a corresponding first range, such as 50-60°C or 85-90°C, the heater restarts. During the drying process, the heater is continuously started or stopped in a cycle by detecting the temperature inside the drying drum or the compressor's exhaust temperature until drying is complete. When the air humidity inside the drying drum reaches the preset humidity S1 (e.g., 50%-55%), the compressor in the dryer stops running, and the air intake valve closes. The fan continues to run for a period of time (e.g., 1 minute) before the dryer stops.

[0078] For the second preset mode:

[0079] In this invention, after the dryer is started, the motor drives the fan and the drying drum to rotate, while the heater starts to heat the circulating air. At this time, the air inlet valve is closed. After a preset time (e.g., 1 minute), the compressor starts. Because the heater is running, the temperature inside the drying drum (drum) and the exhaust temperature of the compressor continuously rise. When the temperature inside the drying drum rises to a first range (e.g., around 50-60°C) or the exhaust temperature of the compressor rises to a corresponding preset first range (usually greater than 85°C), the heater stops heating, and the air inlet valve closes. Because the heater stops heating, the temperature inside the drying drum and the exhaust temperature of the compressor generally remain stable or rise slowly. When the temperature inside the drying drum continues to rise to a second range (e.g., 60-65°C), or the exhaust temperature of the compressor rises to a corresponding preset second range (e.g., a safe temperature range, greater than 90°C), the air inlet valve opens.

[0080] Furthermore, as the heater stops heating and the air inlet valve opens, the temperature inside the drying drum and the compressor's exhaust temperature drop rapidly. When the temperature inside the drying drum (or the compressor's exhaust temperature) drops to the corresponding first range, for example, the temperature inside the drying drum drops to 50-60℃, or the compressor's exhaust temperature drops to 85-90℃, the air inlet valve closes again. During the drying process, the air inlet valve is continuously opened and closed in a cycle by detecting the temperature inside the drying drum or the compressor's exhaust temperature until drying is complete. When the air humidity inside the drying drum reaches the preset humidity S1 (e.g., 50%-55%), the compressor in the dryer stops running, and the air inlet valve closes. The fan continues to run for a period of time (e.g., 1 minute) before the dryer stops.

[0081] Based on the same inventive concept, embodiments of this specification provide a dryer control device, such as... Figure 5 As shown, the device includes: a data acquisition module 501 and a control module 502, wherein:

[0082] The acquisition module 501 is used to monitor the temperature parameters of the dryer after the dryer has been running for a preset time. The temperature parameters are used to characterize the temperature of the target components that make up the dryer.

[0083] The control module 502 is used to perform corresponding drying control on the air intake valve and / or heater in the dryer according to the monitored temperature parameters.

[0084] In some embodiments, the apparatus further includes a determining module 503, wherein:

[0085] The determining module 503 is used to determine the working mode of the dryer;

[0086] The control module 502 is specifically used to perform corresponding drying control on the air intake valve and / or heater in the dryer according to the monitored temperature parameters in the working mode.

[0087] In some implementations, the operating mode is a preset first mode, and the control module 502 is specifically used for:

[0088] The following steps are repeated in the preset first mode until the air humidity inside the drying drum of the dryer reaches the preset humidity:

[0089] When the temperature parameters of the dryer are within the first range, the air inlet valve is opened and the heater continues to heat, so that the temperature parameters of the dryer continue to rise.

[0090] When the temperature parameter of the dryer is within the second range, the heater is stopped to reduce the temperature parameter of the dryer.

[0091] Wherein, the upper limit threshold of the first range is less than or equal to the lower limit threshold of the second range.

[0092] In some implementations, the operating mode is a preset second mode, and the control module 502 is specifically used for:

[0093] The following steps are repeated in the preset second mode until the air humidity inside the drying drum of the dryer reaches the preset humidity:

[0094] When the temperature parameter of the dryer is within the third range, the heater stops heating and the air inlet valve remains closed, and the temperature parameter of the dryer continues to rise;

[0095] When the temperature parameter of the dryer is within the fourth range, the air inlet valve is opened to reduce the temperature parameter of the dryer.

[0096] Wherein, the upper limit threshold of the third range is less than or equal to the lower limit threshold of the fourth range.

[0097] In some embodiments, the device further includes a processing module 504, wherein:

[0098] The processing module 504 is used to stop the operation of the compressor in the dryer and close the air intake valve after detecting that the air humidity in the drying drum of the dryer has reached the preset humidity.

[0099] In some implementations, the determining module 503 is specifically used to: receive user interaction instructions and parse the user interaction instructions to obtain the working mode of the dryer.

[0100] Regarding the above-mentioned device, the specific functions of each module have been described in detail in the embodiments of the air conditioning control method provided in this specification, and will not be elaborated here.

[0101] Based on the same inventive concept, embodiments of the present invention provide another clothes dryer, including an air inlet valve and a heater, and optionally may also include... Figure 2 Other components are shown. For example... Figure 6 As shown, the dryer also includes a memory 604, a processor 602, and a computer program stored in the memory 604 and executable on the processor 602. When the processor 602 executes the program, it implements the aforementioned air conditioning control method.
