[0002] At present, people have a new understanding of the necessity of household cleanliness and hygiene. For example, due to the influence of the coronavirus, people may be contaminated with viruses and other pollutants when going out, which may increase the chance of infection, or they may be contaminated with dust and other debris when going out, which may easily affect the cleanliness of the house. Residents need to take effective protection and cleaning when they go out and come home. However, for families, cleaning and disinfection measures are limited. Usually, they can only use operations such as spraying alcohol and washing hands. It is also difficult to change clothes immediately. Therefore, families usually lack a more comprehensive cleaning and disinfection measure.

However, these devices are usually complicated, and in family life, the air blowing cannot be controlled, so that when the air is blown for disinfection and dust removal, it cannot provide users with a good user experience. For example, in winter, which is prone to the occurrence of coronavirus, the ambient temperature is usually low. In this case, it is difficult to control the air outlet temperature, resulting in a poor user experience. Summary of the invention

[0023] When the first air outlet baffle, the second air outlet baffle and the third air outlet baffle are all located outside the air outlet structure, and the first return air baffle, the second return air baffle and the third return air baffle are located outside the return air structure, the first air outlet baffle is sealed with the first return air baffle, the second air outlet baffle is sealed with the second return air baffle, the third air outlet baffle is sealed with the third return air baffle, and the second air outlet baffle is sealed with the first air outlet baffle and the third air outlet baffle respectively, and the second return air baffle is sealed with the first return air baffle and the third return air baffle respectively, and the air flow channel is formed between the first air outlet baffle, the second air outlet baffle, the third air outlet baffle, the first return air baffle, the second return air baffle and the third return air baffle.

In order to avoid directly turning on the first fan assembly and the air flow nozzle to output unheated cold air, which leads to a decrease in comfort, the tube temperature of the heat exchanger is obtained when the heating mode is started. When the tube temperature of the heat exchanger rises to a certain level and the tube temperature is greater than the first preset tube temperature, the air temperature in the surface air outlet structure can rise to an appropriate level. At this time, the first fan assembly and the air flow nozzle are controlled to start, thereby ensuring the output of hot air and improving the comfort of the user.

DETAILED DESCRIPTION

[0060] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0061] At the same time, it should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0062] Reference Figure 1 As shown, the present invention proposes a clean system, including an air conditioner outdoor unit, an air outlet structure 1, a return air structure 2, a first fan assembly 3, a second fan assembly 4, a heat exchanger 5 and a plurality of air flow nozzles 6, the air outlet structure 1 and the return air structure 2 are arranged opposite to each other, an air outlet 101 is formed on the air outlet structure 1, a return air outlet 201 is formed on the return air structure 2, the air flow nozzle 6 is located at the air outlet 101, the first fan assembly 3 and the heat exchanger 5 are located in the air outlet structure 1, the second fan assembly 4 is located in the return air structure 2, the heat exchanger 5 is connected to the air conditioner outdoor unit, and a fully closed or semi-closed air flow channel is suitable for forming between the air outlet 101 and the return air outlet 201.

[0063] In family life, when blowing air to disinfect and remove dust from the human body, the blowing of air cannot be controlled, so that the user cannot have a good experience when blowing air to disinfect and remove dust. For example, in winter, which is prone to causing coronavirus, the ambient temperature is usually low. In this case, it is difficult to control the air outlet temperature, resulting in a poor user experience.

[0064] The clean system in the embodiment of the present invention is provided with an air outlet structure 1 and an air return structure 2 relative to each other, wherein the air outlet structure 1 and the air return structure 2 form a cavity and respectively form an air outlet 101 and an air return port 201 for air outlet and air return, and a plurality of air flow nozzles 6 are provided at the air outlet, so that the air flow nozzles 6 eject high-speed airflow. Specifically, the air flow nozzles 6 can be connected to an air supply device to realize the ejection of high-speed airflow. The air supply device is provided in the air outlet structure 1, and the plurality of air flow nozzles 6 can be connected to the air supply device 1 through a connecting structure or a support structure. The supporting structure is connected and supported with the air outlet structure 1, so that it is located at the air outlet 101, and a fully enclosed or semi-enclosed airflow channel is formed between the air outlet 101 and the return air outlet 201. Based on this, when the second fan assembly 4 is in action, the air outlet 101 and the air flow nozzle 6 are returned through the return air outlet 201 to form air outflow and return air. Optionally, based on the relative arrangement of the air outlet structure 1 and the return air structure 2, the air outlet 101 can also be spatially opposite to the return air outlet 201, and the air outlet 101 and the return air outlet 201 can be spaced opposite to each other. The airflow nozzle 6 at the outlet 101 can spray out a high-speed clean airflow. When the user uses the clean system, the user can be located in the airflow channel, so that the high-speed airflow can act on the user, thereby blowing away dust, harmful bacteria or viruses on the surface of the user to clean the user, and can clean and disinfect the user, and then be recovered by the second fan assembly 4 through the return air outlet 201. Based on the fully enclosed or semi-enclosed airflow channel formed, the space used for disinfection of the user can be reduced to a certain extent, and the space can be sealed to a certain extent to prevent pollutants from leaking out during the clean treatment, so as to facilitate the clean treatment. A heat exchanger 5 is also provided in the air outlet structure 1. The heat exchanger 5 can exchange heat with the air in the air outlet structure 1 based on the refrigerant, thereby generating hot air or cold air. Based on the exhaust of the first fan assembly 3 and the air outlet 101, the air in the airflow channel between the air outlet 101 and the return air outlet 201 can be temperature-regulated, and at the same time, it can be recovered by the second fan assembly 4 through the return air outlet 201. Figure 1 In the figure, the direction indicated by the arrow is the direction of airflow between the air outlet structure 1 and the return air structure 2. For example, the heat exchanger 5 heats the air to provide hot air, thereby raising the temperature to avoid the problem of reduced comfort caused by direct blowing of cold air when the user's air is discharged for disinfection and dust removal. Optionally, cold air can also be provided to lower the temperature and provide a certain amount of cold air to bring a comfortable experience. Since a fully enclosed or semi-enclosed space is formed between the air outlet 101 and the return air outlet 201, it can provide a better temperature control effect and bring a more comfortable experience to the user.

[0065] Among them, the structure that can form a fully enclosed or semi-enclosed space can be selectively set according to the actual scene. Figure 2As shown, in this embodiment, the air outlet 101 is opposite to the return air outlet 201, and a sealed door-type structure that can be sealed is arranged on the upper side and the front and rear sides of the space therebetween, so as to surround and seal the area between the air outlet 101 and the return air outlet 201, such as only surrounding three sides, but the overall area for air circulation is reduced, so that a half-closed airflow channel is used for users to perform cleaning treatment, which is beneficial to the concentration of high-speed airflow and temperature regulation during cleaning treatment, and to prevent pollutants from leaking out to a certain extent, or more sealed door-type structures are arranged to surround the upper, lower, front and rear sides of the area between the air outlet 101 and the return air outlet 201, so as to form a fully sealed airflow channel, so as to further improve the cleaning treatment effect and isolate the leakage of pollutants. In an actual use scenario, the sealed door can cooperate with the wall or floor of the corridor or aisle, and only three sets of sealed door-type structures are arranged as in this embodiment to form a fully sealed airflow channel, thereby saving related materials, saving costs, and achieving a better sealing effect.

[0066] In one applicable scenario of the present invention, it is applied to home or work environments. In these environments, air conditioners are usually installed, such as high-power central air conditioners, etc. For the clean system in the embodiment of the present invention, it is usually necessary to provide a structure that can regulate the refrigerant when setting the heat exchanger 5. For the home or work environment, setting an additional compressor structure will increase additional costs. Therefore, for the clean system in the present invention, the heat exchanger 5 is connected to the air conditioner outdoor unit through a pipeline. Specifically, the compressor of the air conditioner outdoor unit is connected, so that the air conditioner outdoor unit is used to adjust the refrigerant temperature of the heat exchanger 5, and it is convenient to adjust the refrigerant temperature, thereby saving costs and improving comfort. Among them, when the clean system based on the air-conditioning outdoor unit is installed and arranged in a home environment or a work environment, it can be similar to the installation arrangement of a central air-conditioning. The air outlet structure 1 and the return air structure 2 can be set in opposite walls in an aisle or corridor, or the air outlet structure 1 and the return air structure 2 can be opposite wall structures in an aisle or corridor, and air outlets are opened on the wall corresponding to the air outlet 101 and the return air outlet 201.

[0068] In this embodiment, the power of the second fan assembly 4 is greater than the power of the first fan assembly 3, which may mean that, when the specifications of the motor and the fan blades in the fan assembly are the same, the fan speed in the air outlet structure 1 is greater than the fan speed in the return air structure 2, or the number of motors and fan blades in the air outlet structure 1 is greater than the number of motors and fan blades in the return air structure 2, so that negative pressure can be formed based on the flow of air to prevent dust and pollutants from being dispersed into the air. Optionally, the area of ​​the return air port 201 is greater than the area of ​​the air outlet 101, such as the length and width of the return air port 201 are greater than the length and width of the air outlet 101, so as to further prevent dust and pollutants from being dispersed into the air.

[0069] An optional embodiment of the present invention further includes an electric heater 7, which is located in the air outlet structure 1.

In this way, the user can be located in the airflow channel for cleaning, disinfection and dust removal. Based on this, the cleaning effect can be improved to a certain extent, and due to the sealing and shielding of each sealing component, the spillage of pollutants can be avoided to a certain extent. In certain settings, it can be coordinated with the ground and walls. For example, when the clean system is applied to a corridor or aisle, the first sealing component 901 and the third sealing component 903 can be placed on the front and back sides of the corridor or aisle, and accordingly, the second sealing component 902 can be located between the first sealing component 901 and the third sealing component 903, and located on the upper side of the corridor or aisle, so that the three cooperate with the ground, thereby forming an airflow channel while surrounding it. A relatively sealed area is formed for conducting the airflow between the air outlet 101 and the return air outlet 201. When the user is in the enclosed area and performs cleaning treatments such as disinfection and dust removal, the first sealing component 901, the second sealing component 902, and the third sealing component 903 can fit and seal with each other, so that based on the sealing shielding of the ground and the sealing components, air overflow and leakage of pollutants or dust can be better prevented. In order to realize the pedestrian function of the corridor or aisle, the first sealing component 901, the second sealing component 902 and the third sealing component 903 can be a movable sealing door structure, such as the first sealing component 901, the second sealing component 902 and the third sealing component 903 are movably connected to the air outlet structure 1 and / or the return air structure 2, for example, the sealing component can be retracted, slid, rotated, etc., so that it can move to the corresponding position to form an airflow channel when sealing is required, and unfolded at other times for easy passage.

[0079] In an optional embodiment of the present invention, it also includes a plurality of driving mechanisms, which are respectively located at the air outlet structure 1 and the air return structure 2, the first sealing component 901 includes a first air outlet baffle 911 and a first air return baffle 921 that cooperate with each other, the second sealing component 902 includes a second air outlet baffle 912 and a second air return baffle 922 that cooperate with each other, and the third sealing component 903 includes a third air outlet baffle 913 and a third air return baffle 923 that cooperate with each other; the first air outlet baffle 911, the second air outlet baffle 912 and the third air return baffle 923 The third air outlet baffle 913 is respectively connected to the driving mechanism at the air outlet structure 1, the first return air baffle 921, the second return air baffle 922 and the third return air baffle 923 are respectively connected to the driving mechanism at the return air structure 2, the first air outlet baffle 911, the second air outlet baffle 912 and the third air outlet baffle 913 are suitable for being driven by the driving mechanism to the inside of the air outlet structure 1 or the outside of the air outlet structure 1, the first return air baffle 921, the second return air baffle 922 and the third return air baffle 923 are suitable for being driven by the driving mechanism to the inside of the air outlet structure 1 or the outside of the air outlet structure 1 When the first air outlet baffle 911, the second air outlet baffle 912 and the third air outlet baffle 913 are all located outside the air outlet structure 1, and the first return air baffle 921, the second return air baffle 922 and the third return air baffle 923 are located outside the return air structure 2, the first air outlet baffle 911 is sealed with the first return air baffle 921, the second air outlet baffle 912 is sealed with the second return air baffle 922, and the third return air baffle 923 is sealed with the second return air baffle 923. The air baffle 913 is tightly fitted and sealed with the third return air baffle 923, and the second air outlet baffle 912 is tightly fitted and sealed with the first air outlet baffle 911 and the third air outlet baffle 913 respectively, and the second return air baffle 922 is tightly fitted and sealed with the first return air baffle 921 and the third return air baffle 923 respectively, and the air flow channel is formed between the first air outlet baffle 911, the second air outlet baffle 912, the third air outlet baffle 913, the first return air baffle 921, the second return air baffle 922 and the third return air baffle 923.

[0080] Reference Figure 2 and 3 As shown, in this embodiment, the first sealing component 901, the second sealing component 902 and the third sealing component 903 are all door-type structures that can be opened and closed, and each of them includes two partition structures, one of which can be driven to move by a driving mechanism, so that it is located inside or outside the air outlet structure 1 after the movement, and the other partition structure can be driven to move by a driving mechanism, so that it is located inside or outside the air return structure 2 after the movement. Figure 2 and 3The direction indicated by the middle arrow is the opening and closing movement direction of the partition in the sealing component. When the partition of the same sealing component moves to the outside of the air outlet structure 1 and the return air structure 2, the two partitions cooperate with each other to form a sealing door structure similar to an opening and closing door. When all partitions are located outside the air outlet structure 1 and the return air structure 2, the partitions fit together and seal to form the above-mentioned air flow channel to allow air to circulate between the air outlet 101 and the return air outlet 201, prevent gas overflow, and prevent pollutants or dust from leaking. When the partition moves to the inside of the air outlet structure 1 and the return air structure 2, the sealing component is stored. The sealing component based on the opening and closing door form is driven by a driving mechanism so that it can be conveniently stored in the air outlet structure 1 and the return air structure 2 to avoid affecting the passage of the aisle and preventing pollutants or dust from leaking.

[0081] In an actual application scenario of the present invention, for example, when the clean system is applied to a corridor or a hallway, the first air outlet baffle 911 and the first return air baffle 921 of the first sealing component 901 can be placed at the front side of the corridor or the hallway, and correspondingly, the third air outlet baffle 913 and the third return air baffle 923 of the third sealing component 903 are placed at the rear side of the corridor or the hallway, and are opposite to the first air outlet baffle 911 and the first return air baffle 921. At this time, the second air outlet baffle 912 and the second return air baffle 922 of the second sealing component 902 are placed between the first sealing component 901 and the third sealing component 903, and are located on the upper side of the corridor or the hallway, so that the three cooperate with the ground, and based on the second air outlet baffle 912 and the first air outlet baffle 911 and the third air outlet baffle The plate 913 is fitted and sealed, the second return air baffle 922 is fitted and sealed with the first return air baffle 921 and the third return air baffle 923, and the air outlet baffle and the return air baffle of the same sealing component are fitted and sealed with each other, so as to form an airflow channel and enclose a relatively sealed area for the conduction of airflow between the air outlet 101 and the return air outlet 201. When the user is in the enclosed area and performs cleaning treatments such as disinfection and dust removal, the sealing shielding based on the ground and the baffles in the sealing component can better prevent air overflow and prevent pollutants or dust from leaking. In addition, a driving mechanism is set to drive the baffle to move, so that when sealing is required, the baffle is driven to move to the corresponding position to form an airflow channel, and is unfolded at other times to facilitate the user to pass through. The driving mechanism located in the air outlet structure 1 and the return air structure 2 can also correspond to the number of baffles, which can be multiple, so as to perform one-to-one driving, or one, so as to perform simultaneous driving.

[0082] In an optional embodiment of the present invention, a sensing device is further included, wherein the sensing device is communicatively connected to a controller of the cleaning system, and the controller is suitable for controlling the operating state of the cleaning system according to the sensing condition of the user by the sensing device.

[0083] In this embodiment, a sensing device may be provided to communicate with the controller of the clean system for sensing the user so as to control the clean system. Specifically, the position of the sensing device may be set according to actual conditions to facilitate control or avoid miscontrol. For example, a sensing device, such as an infrared sensor or a touch panel, may be provided at a certain height in an aisle or corridor and communicated with the controller. In this way, the operating state of the clean system may be controlled according to the sensing conditions of the sensing device. For example, when the infrared sensor senses that there is an obstruction, the clean system may be started, etc. Alternatively, the clean system may be controlled to operate in different operating modes according to the duration of the obstruction, so as to facilitate the control of the clean system. For the touch panel, the actual control of the clean system may be performed by determining whether the touch is on, the touch area, the touch gesture, etc.

[0084] like Figure 4 As shown, the present invention also proposes a control method for a clean system. Based on the above clean system, the control method for the clean system includes:

[0085] S1 obtains the operation mode instruction and the indoor ambient temperature;

[0086] S2 controls the operation mode of the clean system according to the operation mode instruction and the indoor ambient temperature.

[0087] The control method of the clean system of this embodiment can achieve the same beneficial effects as the above-mentioned clean system, and when controlling the clean system, an operation mode instruction is obtained, which reflects the expected operating state of the clean system set by the user. Based on the operation mode instruction and the indoor ambient temperature, the operation mode of the clean system is actually controlled to reasonably control the working state of the clean system, thereby providing a more comfortable experience when disinfecting and removing dust for the user.

[0088] The operation mode instruction may be provided by a device that outputs instructions, such as a remote control device, a sensing device, etc. For example, the cleaning system further includes a remote control device or a sensing device, and the acquisition of the operation mode instruction may include:

[0089] receiving an operation mode instruction sent by the remote control device; or,

[0090] The sensing signal sent by the sensing device is received, and the operating mode instruction is generated according to the sensing signal.

[0091] For the remote control device, corresponding physical buttons or display areas of the touch screen can be set thereon, such as buttons for switch, blowing time, blowing speed, operation mode, etc., or touch areas of the touch screen of the remote control panel, corresponding to corresponding control instructions, so that when receiving these instructions, the corresponding control of the system can be closer. Specifically, the obtained operation mode instructions can be the operation mode instructions sent by the remote control device, which are used to control the operation mode of the clean system in combination with the indoor ambient temperature.

[0092] For the sensing device, such as an infrared sensor, it can detect whether there is infrared blocking. For example, when blocked, a blocking signal is sent, which corresponds to the start-up signal of the clean system. Alternatively, according to the different blocking time, the blocked infrared sensor position is different, corresponding to different operating mode instructions of the clean system. In this way, the obtained operating mode instruction can be the operating mode instruction corresponding to the sensing signal sent by the sensing device, so as to facilitate the control of the clean system.

[0093] Before obtaining the operating mode instruction, it also includes: receiving the start-up operation instruction sent by the remote control device; or receiving the sensing signal sent by the sensing device, and generating the start-up instruction according to the sensing signal, so that the start-up of the cleaning system can be controlled according to the start-up instruction, such as preheating start, or starting in the operating mode before shutdown, etc.

[0094] In an optional embodiment of the present invention, the operation mode instruction includes a warm air mode instruction and a ventilation mode instruction; and the operation mode of the clean system controlled according to the operation mode instruction and the indoor environment temperature includes:

[0095] When the operation mode instruction is the warm air mode instruction, and the indoor ambient temperature is less than or equal to the first preset ambient temperature, the clean system is controlled to operate in a heating mode, and the heating mode includes: controlling the compressor of the air conditioner outdoor unit to start to transport hot refrigerant to the heat exchanger 5;

[0096] When the operation mode instruction is the ventilation mode instruction, the clean system is controlled to operate in the ventilation mode, and the ventilation mode includes: controlling or keeping the compressor turned off, and starting or keeping the airflow nozzle 6 to supply air;

[0097] When the operation mode instruction is the warm air mode instruction and the indoor ambient temperature is greater than the first preset ambient temperature, the clean system is controlled to operate in the ventilation mode.

[0098] In this embodiment, the operation mode instruction includes a warm air mode instruction and a ventilation mode instruction. Correspondingly, the clean system can output hot air or normal temperature air. When the operation mode instruction is a warm air mode instruction and the indoor ambient temperature is less than or equal to the first preset ambient temperature, it indicates that the operation mode set by the user at this time is a mode that requires hot air to be provided. At the same time, the indoor ambient temperature obtained at this time is also relatively small. The first preset ambient temperature can be set by the user according to actual conditions. For example, when it is set to a temperature value between 16-18°C, the clean system is controlled to operate in a heating mode. In this heating mode, the compressor of the air conditioner outdoor unit is controlled to start, thereby transporting hot refrigerant to the heat exchanger 5 for heat exchange of the air in the air outlet structure 1. At this time, it can be selectively set to open the airflow nozzle 6 and the first fan assembly 3 at the same time or keep it closed. Under normal circumstances, air heating requires a certain process. Therefore, it is preferably not to open the airflow nozzle 6 and the first fan assembly 3 at the same time. After the air is heated to a temperature that has no effect on the user, the airflow nozzle 6 and the first fan assembly 3 are opened to provide a comfortable experience.

[0099] When the operation mode instruction is a ventilation mode instruction, the air in the air outlet structure 1 does not need to be heat exchanged. In the ventilation mode, the compressor is turned off and only high-speed air is supplied through the air flow nozzle 6.

[0100] When the operating mode instruction is a warm air mode instruction, but the indoor ambient temperature is greater than the first preset ambient temperature, it means that although the user has set it to warm air mode, the indoor ambient temperature is moderate at this time, and air can be supplied in ventilation mode without causing a decrease in user comfort, thereby performing reasonable air supply control and saving energy and reducing consumption.

[0101] In an optional embodiment of the present invention, the method further includes: when the clean system is operated in the heating mode, the operating state of the first fan assembly 3 and the airflow nozzle 6 is controlled according to the tube temperature of the heat exchanger 5; the operating state of the first fan assembly 3 and the airflow nozzle 6 is controlled according to the tube temperature of the heat exchanger 5, including:

[0102] When the pipe temperature is greater than the first preset pipe temperature, the first fan assembly 3 and the air flow nozzle 6 are controlled to start.

[0103] In this embodiment, in the heating mode, it takes a certain amount of time for the air temperature in the air outlet structure 1 to rise. In order to avoid directly turning on the first fan assembly 3 and the air flow nozzle 6 to output unheated cold air, which would lead to a decrease in comfort, the tube temperature of the heat exchanger 5 is obtained when the heating mode is started. When the tube temperature of the heat exchanger rises to a certain level, in this embodiment, specifically when the tube temperature is greater than the first preset tube temperature, the air temperature in the surface air outlet structure 1 can rise to an appropriate level. At this time, the first fan assembly 3 and the air flow nozzle 6 are controlled to start, thereby ensuring the output of hot air and improving the comfort of the user.

[0104] In an optional embodiment of the present invention, the method further includes: when the clean system operates in the heating mode, controlling the operating state of the compressor according to the tube temperature of the heat exchanger 5; controlling the operating state of the compressor according to the tube temperature of the heat exchanger 5 includes:

[0105] When the pipe temperature is lower than a second preset pipe temperature, controlling the compressor to increase frequency by a first preset number of steps;

[0106] When the pipe temperature is greater than the sum of the second preset pipe temperature and the first preset judgment value, and less than the sum of the second preset pipe temperature and the second preset judgment value, controlling the compressor to maintain frequency operation;

[0107] When the pipe temperature is greater than the sum of the second preset pipe temperature and the second preset judgment value, and the duration reaches a first preset duration, the compressor is controlled to reduce the frequency by a second preset step number, and the second preset step number is less than the first preset step number.

[0108] In this embodiment, when the heating mode is running, the operating state of the compressor is controlled in real time according to the tube temperature of the heat exchanger 5, including increasing the frequency, decreasing the frequency, and maintaining the frequency of the compressor, so as to make the compressor operate reasonably and ensure that the tube temperature of the heat exchanger 5 is within a suitable temperature range. In this way, the temperature of the hot air output from the air outlet 101 is within a better temperature range to improve comfort.

[0109] Among them, the second preset pipe temperature can be set to 42°C, the first preset step number can be 2Hz / s, the first preset step number can be 1Hz / s, the first preset judgment value is 2°C, the second preset judgment value is 6°C, and the first preset time is 5s. At this time, the control of the compressor is:

[0110] When the pipe temperature is less than 42℃, the compressor frequency is controlled to increase by 2HZ / s.

[0111] When the pipe temperature is greater than 42℃+6℃ and lasts for 5S, the compressor frequency is controlled to be reduced by 1HZ / s.

[0112] When the pipe temperature is greater than 42℃+2℃ and less than or equal to 42℃+6℃, the compressor frequency is controlled to maintain the current frequency.

[0113] Optionally, a third preset judgment value, such as 4° C., is set to further control the compressor.

[0114] For example, when the pipe temperature is greater than 42°C + 4°C and less than or equal to 42°C + 6°C, the compressor frequency is controlled to maintain the current frequency and the compressor frequency is prohibited from increasing.

[0115] In this way, the compressor can be adjusted reasonably, the pipe temperature can be controlled reasonably, and then the air outlet temperature can be controlled reasonably to improve comfort.

[0116] In an optional embodiment of the present invention, the operation mode instruction further includes a cold air mode instruction; and the operation mode of controlling the clean system according to the operation mode instruction and the indoor ambient temperature further includes:

[0117] When the operation mode instruction is the cold air mode instruction, and the indoor ambient temperature is greater than or equal to the second preset ambient temperature, the clean system is controlled to operate in a cooling mode, and the cooling mode includes controlling the compressor of the air conditioner outdoor unit to start to transport cold refrigerant to the heat exchanger 5, and starting the air flow nozzle 6 to supply air;

[0118] When the operation mode instruction is the cold air mode instruction and the indoor ambient temperature is lower than the second preset ambient temperature, the clean system is controlled to operate in the ventilation mode.

[0119] In this embodiment, the operation mode instruction also includes a cold air mode instruction. Correspondingly, the clean system can output cold air. When the operation mode instruction is a cold air mode instruction and the indoor ambient temperature is greater than or equal to the second preset ambient temperature, it indicates that the operation mode set by the user at this time is a mode that requires providing cold air. At the same time, the indoor ambient temperature obtained at this time is also relatively high. The second preset ambient temperature can be set by the user according to actual conditions. For example, when it is set to a temperature value between 26-28°C, the compressor is controlled to start to transport cold refrigerant to the heat exchanger 5 to reduce the air temperature in the air outlet structure 1, thereby reducing the air outlet temperature of the air outlet 101. At the same time, the airflow nozzle 6 is started to supply air. Since the airflow nozzle 6 outputs high-speed airflow, it can reduce the user's body surface temperature to a certain extent, and will not cause a decrease in comfort. When the air temperature is reduced, the user's comfort can be improved.

[0120] When the indoor ambient temperature is low, although the cold air mode is set, the ventilation mode is also started at this time to avoid unnecessary temperature adjustment due to user misoperation, thereby reducing energy consumption and achieving reasonable control of the clean system.

[0121] In an optional embodiment of the present invention, the method further includes: when the clean system operates in the cooling mode, the operating state of the compressor is controlled according to the tube temperature of the heat exchanger 5; the controlling the operating state of the compressor according to the tube temperature of the heat exchanger 5 includes:

[0122] When the pipe temperature is less than the difference between the third preset pipe temperature and the third preset judgment value, and the duration reaches the first preset duration, controlling the compressor to reduce the frequency by a first preset number of steps;

[0123] When the pipe temperature is greater than or equal to the difference between the third preset pipe temperature and the third preset judgment value, and the pipe temperature is less than the third preset pipe temperature, controlling the compressor to maintain frequency operation;

[0124] When the pipe temperature is greater than the sum of the third preset pipe temperature and the first preset judgment value, and the duration reaches the first preset duration, the compressor is controlled to increase the frequency with a second preset step number, and the second preset step number is smaller than the first preset step number.

[0125] In this embodiment, when the cooling mode is running, the operating state of the compressor is controlled in real time according to the pipe temperature of the heat exchanger 5, including increasing the frequency, decreasing the frequency, and maintaining the frequency of the compressor, so that the compressor can operate reasonably and ensure that the pipe temperature of the heat exchanger 5 is within a suitable temperature range. In this way, the temperature of the cold air output from the air outlet 101 is within a better temperature range to improve comfort.

[0126] Among them, the third preset pipe temperature can be set to 22°C, the third preset judgment value can be set to 4°C, the first preset time can be 5s, the first preset step number can be set to 2Hz / s, the first preset judgment value is also set to 2°C, and the second preset step number is also set to 1Hz / s. At this time, the control of the compressor is:

[0127] When the pipe temperature is less than 22℃-4℃ and lasts for 5S, the compressor frequency is controlled to reduce by 2HZ / s.

[0128] When the pipe temperature is greater than 22°C-4°C and less than 22°C, the compressor is controlled to maintain frequency operation.

[0129] When the pipe temperature is greater than 22°C + 2°C and lasts for 5 seconds, the compressor frequency is controlled to increase by 1 Hz / s.

[0130] Optionally, the compressor is further controlled by using a first preset judgment value.

[0131] For example, when the pipe temperature is less than 22°C-2°C, and the pipe temperature is greater than or equal to 22°C-4°C, the compressor is controlled to maintain frequency operation, and the compressor frequency is controlled to prohibit frequency reduction.

[0132] When the pipe temperature is ≥22°C-2°C and the pipe temperature is <22°C, the compressor is controlled to maintain frequency operation, and the compressor frequency is controlled to be statically increased.

[0133] In this way, when operating in cooling mode, the compressor is adjusted reasonably, the pipe temperature is controlled reasonably, and then the air outlet temperature is controlled reasonably to improve comfort.

[0134] The present invention further proposes a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the control method of the above-mentioned cleaning system is implemented, and the beneficial effects in the embodiments of the present invention are achieved.

[0135] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
