[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

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

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

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

[0031] Specifically, during the drying process, the drying drum can rotate to fully dry and sterilize all positions of the objects to be dried. A closed area is formed between the drying drum, the first connecting pipeline, and the air supply device. Under the operation of the air supply device, the pressure in the closed area is continuously reduced to form a vacuum negative pressure environment. A non-closed area is formed between the drying drum, the second connecting pipeline, and the air supply device to achieve the drying of the objects to be dried. By recycling heat through a heat pump device, it has higher energy efficiency than an electric heating dryer and can significantly reduce energy consumption. The above-mentioned air supply device may be a reversible vacuum fan, which is used to supply air to the first connecting pipeline and the second connecting pipeline respectively.

[0032] In the above embodiment, a drying device is provided. Since the first connecting pipeline is a sealed pipeline, a negative pressure vacuum environment can be created to reduce the evaporation temperature of the water on the clothes, accelerate the evaporation of water, and achieve efficient sterilization of the objects to be dried. At the same time, since the air supply device can supply air to both the first connecting pipeline and the second connecting pipeline, when air is supplied to the second connecting pipeline, the objects to be dried can be dried quickly, and when air is supplied to the first connecting pipeline, the objects to be dried can be sterilized efficiently. Therefore, the above drying device simultaneously improves the effects of both 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] like Figure 2 As shown, the drying device further includes: a pressure sensor 16, which is arranged at one end of the first connecting pipe 11 close to the drying drum 10; a first temperature sensor 17, which is arranged at one end of the first connecting pipe 11 close to the drying drum 10; and a second temperature sensor 18, which is arranged at one end of the second connecting pipe 12 close to the drying drum 10. The pressure sensor can further detect the pressure at the first end of the first connecting pipe, the first temperature sensor can further detect the temperature at the first end of the first connecting pipe, and the second temperature sensor can further detect the temperature at the first end of the second connecting pipe. According to the pressure detection results and the temperature detection results, the rotation speed of the drying drum, the state of the switch valve and the wind direction of the air supply device are further adjusted, and at the same time, the pressure and temperature in the drying process are further ensured to be kept within a safe range.

[0034] Specifically, the pressure sensor can detect the pressure of the first end of the first connecting pipeline when the air supply device supplies air to the second connecting pipeline. The first temperature sensor can detect the temperature of the first end of the first connecting pipeline when the air supply device supplies air to the first connecting pipeline and the second connecting pipeline. The second temperature sensor can detect the temperature of the first end of the second connecting pipeline when the air supply device supplies air to the first connecting pipeline and the second connecting pipeline. The pressure sensor can be a piezoelectric pressure sensor, a capacitive pressure sensor, a strain gauge pressure sensor, and an optical fiber pressure sensor. The temperature sensor can be a thermocouple temperature sensor, a thermistor temperature sensor, an infrared temperature sensor, and an optical fiber temperature sensor.

[0035] like Figure 3 As shown, the heat pump device 13 includes a condenser 19, a compressor 20 and an evaporator 21, wherein 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. The heat pump device can further reduce the energy consumption of the dryer.

[0036] Specifically, the heat pump device in the dryer is an energy-boosting device, and its working principle is similar to that of a compression refrigeration device. It consumes high-quality energy to boost heat from a low-temperature heat source to a high-temperature heat source, thereby achieving the purpose of heating and drying objects. The above-mentioned heat pump device also includes an expansion valve, which is used to throttle and reduce the pressure of the liquid working medium, turning it into a low-temperature and low-pressure liquid or a gas-liquid mixed state.

[0037] The present application also provides a control method for a drying device. The method provided in the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 4 1 is a hardware structure block diagram of a mobile terminal of a drying device control method according to an embodiment of the present invention. Figure 4 As shown, the mobile terminal may include one or more ( Figure 4 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 4 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 4 More or fewer components as shown, or with Figure 4 Different configurations shown.

[0038] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the control method of the drying device in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is realized. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the above-mentioned 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 above-mentioned network specific example may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as 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 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0039] In this embodiment, a control method for 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 can be executed in an order different from that shown here.

[0040] Figure 5 1 is a flow chart of a control method for a drying device according to an embodiment of the present application. Figure 5 As shown, the method comprises the following steps:

[0041] Step S201, a first control step, controlling the switch valve to open, controlling the air supply device to rotate in a first direction, and controlling the heat pump device to operate, so as to dry the object to be dried;

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

[0043] Step S203, a second control step, in which, when the drying process of the object to be dried 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 object to be dried, wherein the second direction is opposite to the first direction;

[0044] Step S204, a second determination step, determining whether the above-mentioned object to be dried has completed the above-mentioned sterilization process;

[0045] Step S205, a first repetition step, in which, when the sterilization process of the object to be dried is completed, the first control step, the first determination step, the second control step and the second determination step are sequentially repeated until a predetermined time 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 connecting pipeline and the second connecting 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 connecting pipeline until a vacuum is formed.

[0047] Through this embodiment, a control method for a drying device is provided. First, the air supply device is controlled to rotate forward to dry the clothes to be dried. After the drying is completed, the air supply device is controlled to rotate backward to create a negative pressure vacuum environment, thereby reducing the evaporation temperature of water on the clothes. While accelerating the evaporation of water, efficient sterilization of the clothes to be dried can also be achieved. By repeating the forward and reverse rotation of the air supply device for multiple times, the drying device can simultaneously improve the effects of both efficient sterilization and rapid drying, thereby solving 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 connecting pipe close to the drying drum, and the second temperature sensor is arranged at one end of the second connecting pipe 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 connecting pipe detected by the first temperature sensor to obtain the first temperature; step S2022, obtaining the temperature of the first end of the second connecting pipe detected by the second temperature sensor to obtain the second temperature; step S2023, determining whether the first temperature and the second temperature are the same, and if the first temperature and the second temperature are the same, determining that the drying process of the object to be dried is completed. This method can further quickly determine whether the drying process of the object to be dried is completed.

[0049] Specifically, after the drying device is turned on, the starting state is the clockwise circulation ventilation heat pump drying mode, the heat pump device is running, the air supply device is rotating forward, and the temperature data fed back by the inlet and outlet temperature sensors of the drying drum is used to determine whether the clothes in the drum are dried. When the inlet and outlet temperatures of the drum are equal, the clothes are dried and the operation ends. When the inlet and outlet temperatures of the drum are not equal, it is further determined whether the inlet air temperature has reached the set maximum temperature value. If it has not reached the set maximum temperature value, the positive circulation ventilation heat pump drying mode continues to operate until the inlet air temperature of the drying drum reaches the set maximum temperature threshold.

[0050] The above step S204 of the present application can be implemented by the following steps: step S2041, obtaining the pressure of the first end of the above first connecting pipeline detected by the above pressure sensor to obtain the target pressure; step S2042, determining whether the above target pressure is less than the pressure threshold; step S2043, when the above target pressure is less than the above pressure threshold, determining that the above object to be baked has completed the above sterilization process. This method can further quickly determine whether the above object to be baked has completed the above sterilization process.

[0051] Specifically, if the air inlet temperature of the drying drum reaches the set maximum temperature, the counterclockwise circulation vacuum drying mode is turned on, the air supply equipment reverses, and a vacuum negative pressure environment is gradually formed in the enclosed area under the operation of the vacuum fan. The set pressure sensor obtains the pressure data reached in the drying drum, and further determines whether the pressure in the drum has reached the set minimum pressure. When the pressure in the drum has not reached the set low pressure, the air supply equipment continues to reverse and vacuum drying is performed; when the pressure in the drying drum reaches the set low pressure, the counterclockwise circulation vacuum drying mode is turned off, and the clockwise circulation ventilation heat pump drying mode is turned on again, and this cycle is repeated to complete the operation process of the drying device in this example.

[0052] The above step S202 can also be implemented in other ways, for example: step S206, a second repetition step, in which, when the above object to be dried has not completed the above drying process, the above first control step and the above first determination step are sequentially repeated at least once until the above object to be dried has completed the above drying process. The above method can further quickly implement the drying process when the above object to be dried has not completed the above drying process.

[0053] The above step S204 can also be implemented in other ways, for example: step S207, the third repetition step, in which, when the above object to be baked has not completed the above sterilization process, the above second control step and the above second determination step are sequentially repeated at least once until the above object to be baked has completed the above sterilization process. The above method can further quickly implement the sterilization process when the above object to be baked has not completed the above sterilization process.

[0054] In order to enable those skilled in the art to more clearly understand the technical solution 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 combination with specific embodiments.

[0055] This embodiment relates to a specific control method of a drying device, such as Figure 6 As shown, the following steps are included:

[0056] Step S1: Turn on the positive cycle ventilation heat pump drying, open the sealed switch and the reversible vacuum fan to rotate forward, and determine whether the inlet and return air temperatures of the drying drum are equal, otherwise execute S2, and end if yes;

[0057] Step S2: Check whether the air inlet temperature has reached the set high temperature value. If yes, execute S3; otherwise, execute S1.

[0058] Step S3: start 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, otherwise execute S3.

[0060] The present application also provides a control device for a drying device. It should be noted that the control device for the drying device in the present application can be used to execute the control method for the drying device provided in the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions thereof will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0061] The control device of the drying device provided in the embodiment of the present application is introduced below.

[0062] Figure 7 Schematic diagram of a control device for a drying device according to an embodiment of the present application. Figure 7 As shown, the device comprises:

[0063] The first control unit 71 is used for the first control step to control the switch valve to open, control the air supply device to rotate in the first direction, and control the heat pump device to work, so as to dry the object to be dried;

[0064] The first determining unit 72 is used for the first determining step to determine whether the drying process of the object to be dried has been completed;

[0065] The second control unit 73 is used for the second control step, when the drying process of the drying object is completed, controlling the switch valve to close and controlling the air supply device to rotate in a second direction to sterilize the drying object, wherein the second direction is opposite to the first direction;

[0066] A second determining unit 74 is used in a second determining step to determine whether the object to be dried has completed the sterilization process;

[0067] The first repeating unit 75 is used for the first repeating step. When the sterilization process of the object to be dried is completed, the first control step, the first determination step, the second control step and the second determination step are sequentially repeated until a predetermined time is reached.

[0068] 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 connecting pipeline and the second connecting 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 connecting pipeline until a vacuum is formed.

[0069] Through this embodiment, a control device for a drying device is provided. First, the air supply device is controlled to rotate forward to dry the clothes to be dried. After the drying is completed, the air supply device is controlled to rotate backward to create a negative pressure vacuum environment, thereby reducing the evaporation temperature of water on the clothes. While accelerating the evaporation of water, efficient sterilization of the clothes to be dried can also be achieved. By repeating the forward and reverse rotation of the air supply device for multiple times, the drying device can simultaneously improve the effects of both efficient sterilization and rapid drying, thereby solving the technical problem of how to improve the drying effect and sterilization effect of the drying device.

[0070] In a specific implementation process, the drying device further includes a first temperature sensor and a second temperature sensor, wherein the first temperature sensor is arranged at one end of the first connecting pipe close to the drying drum, and the second temperature sensor is arranged at one end of the second connecting pipe close to the drying drum, and the first determination unit includes a first acquisition module, a second acquisition module and a determination module, wherein the first acquisition module is used to acquire the temperature of the first end of the first connecting pipe detected by the first temperature sensor to obtain the first temperature; the second acquisition module is used to acquire the temperature of the first end of the second connecting pipe detected by the second temperature sensor to obtain the second temperature; the first determination module is used to determine whether the first temperature and the second temperature are the same, and when the first temperature and the second temperature are the same, it is determined that the drying process of the object to be dried is completed. The device can further quickly determine whether the drying process of the object to be dried is completed.

[0071] Specifically, after the drying device is turned on, the starting state is the clockwise circulation ventilation heat pump drying mode, the heat pump device is running, the air supply device is rotating forward, and the temperature data fed back by the inlet and outlet temperature sensors of the drying drum is used to determine whether the clothes in the drum are dried. When the inlet and outlet temperatures of the drum are equal, the clothes are dried and the operation ends. When the inlet and outlet temperatures of the drum are not equal, it is further determined whether the inlet air temperature has reached the set maximum temperature value. If it has not reached the set maximum temperature value, the positive circulation ventilation heat pump drying mode continues to operate until the inlet air temperature of the drying drum reaches the set maximum temperature threshold.

[0072] The second determination unit of the present application includes a third acquisition module, a second determination module and a third determination module, wherein the third acquisition module is used to acquire the pressure of the first end of the first communication pipeline detected by the pressure sensor to obtain the target pressure; the second determination module is used to determine whether the target pressure is less than the pressure threshold; the third determination module is used to determine that the object to be baked has completed the sterilization process when the target pressure is less than the pressure threshold. This method can further quickly determine whether the object to be baked has completed the sterilization process.

[0073] Specifically, if the air inlet temperature of the drying drum reaches the set maximum temperature, the counterclockwise circulation vacuum drying mode is turned on, the air supply equipment reverses, and a vacuum negative pressure environment is gradually formed in the enclosed area under the operation of the vacuum fan.
