[0028] As introduced in the background, the existing drying technology still has some deficiencies in drying effect and sterilization effect, etc. To solve the above problems, embodiments of the present application provide a drying device, a control method of the drying device and a drying system.

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings in the embodiments of the present application.

[0030] Figure 1 is a structural schematic diagram of a drying device according to an embodiment of the present application. As shown in Figures 1 to 3 the drying device includes a drying drum 10, a first communication pipeline 11, a second communication pipeline 12, a heat pump device 13, a blowing device 14 and a switch valve 15, wherein a first end of the drying drum 10 is in communication with a first end of the first communication pipeline 11, a second end of the drying drum 10 is in communication with a first end of the second communication pipeline 12, a second end of the first communication pipeline 11 is in communication with a first end of the blowing device 14, a second end of the blowing device 14 is in communication with a first end of the heat pump device 13, a second end of the heat pump device 13 is in communication with a second end of the second communication pipeline 12, the switch valve 15 is arranged on a side of the second communication pipeline 12 close to the drying drum 10, the blowing device 14 is used to blow air to the drying drum 10 through the first communication pipeline 11 or the second communication pipeline 12, the first communication pipeline 11 is a sealed pipeline, the second communication pipeline 12 is a non-sealed pipeline, and the drying drum 10 is used to place objects to be dried.

[0031] Specifically, in the drying process, the drying drum can make each position of the to-be-dried objects be sufficiently dried and sterilized by rotation. The drying drum, the first communication pipeline and the air supply device form a closed area, and under the operation of the air supply device, the pressure in the closed area is continuously reduced to form a vacuum negative pressure environment. The drying drum, the second communication pipeline and the air supply device form a non-closed area to realize the drying of the to-be-dried objects. The heat is recycled by the heat pump device, which has higher energy efficiency and can significantly reduce energy consumption compared with the electric heating dryer. The air supply device can be a reversible vacuum fan for air supply to the first communication pipeline and the second communication pipeline respectively.

[0032] In the above embodiment, the first communication pipeline is a sealed pipeline, which can create a negative pressure vacuum environment, reduce the evaporation temperature of the moisture on the clothes, accelerate the evaporation of the moisture, and also realize efficient sterilization of the to-be-dried objects. At the same time, the air supply device can supply air to the first communication pipeline and the second communication pipeline. In the case of air supply to the second communication pipeline, the to-be-dried objects can be quickly dried, and in the case of air supply to the first communication pipeline, the to-be-dried objects can be efficiently sterilized. Therefore, the above drying device improves the effects of efficient sterilization and rapid drying, and solves the technical problem of how to improve the drying effect and sterilization effect of the drying device.

[0033] As shown in Figure 2 The drying device further comprises a pressure sensor 16 arranged at one end of the first communication pipeline 11 close to the drying drum 10, a first temperature sensor 17 arranged at one end of the first communication pipeline 11 close to the drying drum 10, and a second temperature sensor 18 arranged at one end of the second communication pipeline 12 close to the drying drum 10. The pressure sensor can further detect the pressure at the first end of the first communication pipeline, the first temperature sensor can further detect the temperature at the first end of the first communication pipeline, and the second temperature sensor can further detect the temperature at the first end of the second communication pipeline. According to the pressure detection result and the temperature detection result, the rotation speed of the drying drum, the state of the valve and the air direction of the air supply device are further adjusted, and the pressure and temperature in the drying process are further ensured to be within a safe range.

[0034] Specifically, the aforementioned pressure sensor can detect the pressure at the first end of the first connecting pipe when the air supply equipment supplies air to the second connecting pipe. The aforementioned first temperature sensor can detect the temperature at the first end of the first connecting pipe when the air supply equipment supplies air to both the first and second connecting pipes. The aforementioned second temperature sensor can detect the temperature at the first end of the second connecting pipe when the air supply equipment supplies air to both the first and second connecting pipes. The aforementioned pressure sensor can be a piezoelectric pressure sensor, a capacitive pressure sensor, a strain gauge pressure sensor, or a fiber optic pressure sensor. The aforementioned temperature sensor can be a thermocouple temperature sensor, a thermistor temperature sensor, an infrared temperature sensor, or a fiber optic temperature sensor.

The first end of the condenser 19 is the first end of the heat pump device 13, the second end of the condenser 19 is connected to the first end of the compressor 20, the second end of the compressor 20 is connected to the first end of the evaporator 21, and the second end of the evaporator 21 is the second end of the heat pump device 13. This heat pump device can further reduce the energy consumption of the dryer.

[0036] Specifically, the heat pump equipment in a dryer is an energy-boosting device. Its working principle is similar to that of a compression refrigeration device. By consuming high-grade energy, it raises heat from a low-temperature heat source to a high-temperature heat source, thereby achieving the purpose of heating and drying objects. The aforementioned heat pump equipment also includes an expansion valve, used to throttle and reduce the pressure of the liquid working fluid, turning it into a low-temperature, low-pressure liquid or gas-liquid mixture.

[0037] This application also provides a control method for a drying device. The method embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example... Figure 4 This is a hardware structure block diagram of a mobile terminal for a control method of a drying device according to an embodiment of the present invention. Figure 4 As shown, a mobile terminal may include one or more ( Figure 4 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 4 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 4 The more or fewer components shown, or having the sameFigure 4 different configurations.

[0038] The memory 104 can be used to store computer programs, such as software programs of application software and modules, such as a computer program corresponding to the control method of the drying device according to the embodiments of the present application. The processor 102 can execute various functional applications and data processing, i.e., implement the above method, by running the computer program stored in the memory 104. The memory 104 can include a high-speed random access memory, and can further include a non-volatile memory, such as one or more magnetic storage devices, flash memories, or other non-volatile solid-state memories. In some examples, the memory 104 can further include a memory remotely arranged with respect to the processor 102, and the remote memory can be connected to the mobile terminal through a network. Examples of the network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. The transmission device 106 is used to receive or send data via a network. The specific examples of the network can include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet in a wireless manner.

[0039] In the present embodiment, a control method of a drying device running on a mobile terminal, a computer terminal, or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown.

[0040] Figure 5 is a flowchart of the control method of the drying device according to the embodiments of the present application. As Figure 5 shown, the method includes the following steps:

[0041] Step S201, a first control step, controlling the opening of the above-mentioned switch valve, controlling the rotation of the above-mentioned air supply device in the first direction, and controlling the operation of the above-mentioned heat pump device, so as to perform drying treatment on the above-mentioned object to be dried;

[0042] Step S202, a first determination step, determining whether the above-mentioned object to be dried is completed with the above-mentioned drying treatment;

[0043] Step S203, a second control step, in the case that the drying treatment of the drying object is completed, the switch valve is controlled to be closed and the air supply device is controlled to rotate in a second direction to sterilize the drying object, wherein the second direction is opposite to the first direction;

[0044] Step S204, a second determination step, determining whether the sterilization treatment of the drying object is completed;

[0045] Step S205, a first repetition step, in the case that the sterilization treatment of the drying object is completed, the first control step, the first determination step, the second control step and the second determination step are repeated in sequence until a predetermined time length is reached.

[0046] Specifically, in the first control step and the second control step, the rotation of the drying drum is controlled at the same time, which can further improve the efficiency of drying and sterilization. Controlling the air supply device to rotate in the first direction is equivalent to controlling the air supply device to rotate forward, and the switch valve is opened, and the hot air circulates clockwise between the first communication pipeline and the second communication pipeline. Controlling the air supply device to rotate in the second direction is equivalent to controlling the air supply device to rotate reversely, and the switch valve is closed, and the hot air circulates counterclockwise in the first communication pipeline until a vacuum is formed.

[0047] Through the embodiment, a control method of a drying device is provided. First, the air supply device is controlled to rotate forward to dry the drying object, and after the drying is completed, the air supply device is controlled to rotate reversely to create a negative pressure vacuum environment, reduce the evaporation temperature of water on the drying object, accelerate the evaporation of water, and at the same time, high-efficiency sterilization of the drying object can be realized. The drying device can improve the effects of high-efficiency sterilization and rapid drying at the same time, and solves the technical problem of how to improve the drying effect and sterilization effect of the drying device.

[0048] In the specific implementation process, the drying device further includes a first temperature sensor and a second temperature sensor. The first temperature sensor is arranged at one end of the first communication pipeline close to the drying drum, and the second temperature sensor is arranged at one end of the second communication pipeline close to the drying drum. The step S202 can be implemented by the following steps: step S2021, obtaining the temperature of the first end of the first communication pipeline detected by the first temperature sensor to obtain a first temperature; step S2022, obtaining the temperature of the first end of the second communication pipeline detected by the second temperature sensor to obtain a second temperature; step S2023, determining whether the first temperature and the second temperature are the same, and in the case that the first temperature and the second temperature are the same, determining that the drying treatment of the drying object is completed. This method can further quickly determine whether the drying treatment of the drying object is completed.

[0049] Specifically, after the drying device is turned on, the starting state is the clockwise circulating ventilation heat pump drying mode, the heat pump equipment is operated, the air supply equipment is rotated forward, and whether the clothes in the drying drum are dried is determined according to the temperature data fed back by the drying drum inlet and outlet temperature sensor. When the drying drum inlet and outlet temperatures are equal, the clothes are dried, and the operation is ended. When the drying drum inlet and outlet temperatures are not equal, whether the inlet air temperature reaches the set maximum temperature value is further determined. If the set maximum temperature value is not reached, the clockwise circulating ventilation heat pump drying mode is continuously operated until the inlet air temperature of the drying drum reaches the set maximum temperature threshold.

[0050] The step S204 of the present application can be realized by the following steps: a step S2041 of obtaining the target pressure by acquiring the pressure at the first end of the first communication pipeline detected by the pressure sensor; a step S2042 of determining whether the target pressure is less than the pressure threshold; and a step S2043 of determining that the object to be dried completes the sterilization treatment in the case that the target pressure is less than the pressure threshold. The method can further quickly determine whether the object to be dried completes the sterilization treatment.

[0051] Specifically, if the inlet air temperature of the drying drum reaches the set maximum temperature, the counterclockwise circulating vacuum drying mode is turned on at this time, the air supply equipment is reversed, and a vacuum negative pressure environment is gradually formed in the sealed area under the operation of the vacuum fan. The pressure sensor obtains the pressure data reached in the drying drum, and further determines whether the pressure in the drying drum reaches the set minimum pressure. When the pressure in the drying drum does not reach the set low pressure, the air supply equipment continues to reverse and performs vacuum drying. When the pressure in the drying drum reaches the set low pressure, the counterclockwise circulating vacuum drying mode is closed, and the clockwise circulating ventilation heat pump drying mode is turned on again. This continuously circulates to complete the operation process of the drying device in the present example.

[0052] The step S202 can also be realized by other ways, for example: a second repeating step S206 of sequentially repeating the first control step and the first determination step at least once until the object to be dried completes the drying treatment in the case that the object to be dried does not complete the drying treatment. The method can further quickly realize the drying treatment in the case that the object to be dried does not complete the drying treatment.

[0053] The step S204 can also be realized by other ways, for example: a third repeating step S207 of sequentially repeating the second control step and the second determination step at least once until the object to be dried completes the sterilization treatment in the case that the object to be dried does not complete the sterilization treatment. The method can further quickly realize the sterilization treatment in the case that the object to be dried does not complete the sterilization treatment.

[0054] In order for those skilled in the art to more clearly understand the technical solutions of the present application, the implementation process of the control method of the drying device of the present application will be described in detail below in conjunction with specific embodiments.

[0055] The present embodiment relates to a specific control method of a drying device, as shown in Figure 6 The method comprises the following steps:

[0056] Step S1: turn on the positive cycle ventilation heat pump drying, open the airtight switch, and turn on the reversible vacuum fan in the forward direction, determine whether the inlet and return air temperatures of the drying drum are equal, if not, execute S2, if yes, end;

[0057] Step S2: determine whether the inlet air temperature reaches the set high temperature value, if yes, execute S3, if not, execute S1;

[0058] Step S3: turn on the reverse cycle vacuum drying, close the airtight switch, and reverse the reversible vacuum fan;

[0059] Step S4: determine whether the set low pressure is reached, if yes, execute S1, if not, execute S3.

[0060] The present application also provides a control device for a drying device. It should be noted that the control device for a drying device of the present application can be used to execute the control method for a drying device provided by the present application. The device is used to implement the above embodiments and preferred embodiments, and those that have been described will not be repeated. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware, or a combination of software and hardware can also be implemented and conceived.

[0061] The control device for a drying device provided by the present application is described below.

[0062] Figure 7 is a schematic diagram of a control device for a drying device according to the present application. As shown in Figure 7 The device comprises:

[0063] A first control unit 71 is used for a first control step, controls the opening of the above-mentioned switch valve, controls the rotation of the above-mentioned air supply equipment in the first direction, and controls the operation of the above-mentioned heat pump equipment to dry the above-mentioned objects to be dried;

[0064] A first determination unit 72 is used for a first determination step to determine whether the above-mentioned objects to be dried have completed the above-mentioned drying process;

[0065] The second control unit 73 is configured to control the switch valve to be closed and the air supply device to rotate in the second direction for sterilizing the laundry when the drying process is completed.

[0066] The second determination unit 74 is configured to determine whether the sterilization process is completed.

[0067] The first repeating unit 75 is configured to repeat the first control unit, the first determination unit, the second control unit and the second determination unit in sequence until a predetermined time is reached when the sterilization process is completed.

[0068] Specifically, the rotation of the drying drum is controlled in the first control unit and the second control unit, which can further improve the efficiency of drying and sterilization. The rotation of the air supply device in the first direction is equivalent to the forward rotation of the air supply device, and the switch valve is opened, and the hot air circulates clockwise between the first communication pipeline and the second communication pipeline. The rotation of the air supply device in the second direction is equivalent to the reverse rotation of the air supply device, and the switch valve is closed, and the hot air circulates counterclockwise in the first communication pipeline until a vacuum is formed.

[0069] According to the embodiment, the control device of the drying device is provided. First, the air supply device is controlled to rotate forward to dry the laundry, and after the drying is completed, the air supply device is controlled to rotate reversely to create a negative pressure vacuum environment, reduce the evaporation temperature of the moisture on the laundry, accelerate the evaporation of the moisture, and at the same time, high-efficiency sterilization of the laundry can be achieved. The forward rotation and the reverse rotation of the air supply device are repeated multiple times, and the drying device can improve the effects of high-efficiency sterilization and fast drying at the same time, and solves the technical problem of how to improve the drying effect and the sterilization effect of the drying device.

[0070] In the implementation process, the drying device further comprises a first temperature sensor and a second temperature sensor, the first temperature sensor is arranged at one end of the first communication pipeline close to the drying roller, the second temperature sensor is arranged at one end of the second communication pipeline close to the drying roller, the first determination unit comprises a first acquisition module, a second acquisition module and a determination module, wherein the first acquisition module is configured to acquire the temperature of the first end of the first communication pipeline detected by the first temperature sensor to obtain a first temperature; the second acquisition module is configured to acquire the temperature of the first end of the second communication pipeline detected by the second temperature sensor to obtain a second temperature; and the first determination module is configured to determine whether the first temperature and the second temperature are the same, and determine that the to-be-dried object completes the drying treatment in the case that the first temperature and the second temperature are the same. The device can further quickly determine whether the to-be-dried object completes the drying treatment.

[0071] Specifically, after the drying device is turned on, the starting state is a clockwise circulating ventilation heat pump drying mode, the heat pump equipment is running, the air supply equipment is rotating forward, and whether the clothes in the drying roller are completed drying is determined through the temperature data fed back by the drying roller inlet and outlet temperature sensor. When the drying roller inlet and outlet temperatures are equal, the clothes are completed drying, and the running is ended. When the drying roller inlet and outlet temperatures are not equal, it is further determined whether the inlet air temperature reaches the set maximum temperature value. If the set maximum temperature value is not reached, the clockwise circulating ventilation heat pump drying mode is continuously run until the inlet air temperature of the drying roller reaches the set maximum temperature threshold.

[0072] The above-mentioned second determination unit of the present application comprises a third acquisition module, a second determination module and a third determination module, wherein the third acquisition module is configured to acquire the pressure of the first end of the first communication pipeline detected by the pressure sensor to obtain a target pressure; the second determination module is configured to determine whether the target pressure is less than a pressure threshold; and the third determination module is configured to determine that the to-be-dried object completes the sterilization treatment in the case that the target pressure is less than the pressure threshold. The method can further quickly determine whether the to-be-dried object completes the sterilization treatment.

[0073] Specifically, if the air inlet temperature of the drying drum reaches the set maximum temperature, the air supply device is reversed, and a vacuum negative pressure environment is gradually formed in the closed area under the operation of the vacuum fan.
