At present, the integrated fresh air dehumidifiers on the market have a large energy loss in the process of exchanging fresh air, and the dehumidification efficiency is not high.

[0003] In the related art, a solution to the above problem is to provide a solid dehumidifier. The solid dehumidifier includes an upper air duct, a lower air duct, a fresh air component, a return air component and a wind direction switching device. Solid dehumidification modules are arranged in the upper air duct and the lower air duct.

The structures of the first door body 20 and the second door body 30 are designed to be in the shape of an arc plate, and the movement trajectories of the first door body 20 and the second door body 30 are also in an arc trajectory. Compared with the traditional air door that moves in a single direction, the first door body 20 and the second door body 30 are designed to be in the shape of an arc plate, and the first door body 20 and the second door body 30 are controlled to move along the arc trajectory at the same time, so as to realize the movement of the air door between two directions, so as to realize the switching of the first door body 20 between the first air outlet 120 and the third air outlet 140, and the switching of the second door body 30 between the second air outlet 130 and the third air outlet 140.

The motor 410 drives the gear assembly 420 to rotate, and the gear assembly 420 drives the first door body 20 and the second door body 30 to move relative to the housing 10. The motor 410 drives the first door body 20 and the second door body 30 to move relative to the housing 10 by means of gear transmission, thereby improving the control accuracy of the driving assembly 40 on the first door body 20 and the second door body 30.

The processor is configured to execute a control method for the fresh air blower when running the program instructions.

[0115] In some embodiments, in combination Fig.13 As shown, a control method for a fresh air fan is provided, which is applied to the fresh air fan described in any of the above embodiments, and the control method includes:

[0116] S101, the processor obtains indoor humidity;

[0117] S102, the processor determines the operation mode of the fresh air fan according to the indoor humidity;

[0118] S103, the processor controls the operation of the damper mechanism according to the operation mode.

[0119] By adopting the control method for the fresh air fan provided in the embodiment of the present disclosure, it is possible to determine the operation mode adapted to the current air condition according to the indoor humidity, and control the operation of the damper mechanism according to the operation mode to realize the switching of the air path channel. By adopting the control method for the fresh air fan, the intelligence level of the fresh air fan is improved, thereby improving the practicality and reliability of the fresh air fan.

[0120] Exemplarily, the humidity sensor obtains the indoor humidity in real time and feeds back the current indoor humidity to the processor. The processor determines an operating mode adapted to the current air condition according to the indoor humidity. The processor regulates the electric control component according to the determined operating mode to control the operation of the air damper mechanism and realize the switching of the air passage.

[0121] Optionally, the step of controlling the operation of the air damper mechanism according to the operating mode includes: when the operating mode is the fresh air mode, controlling the driving component to drive the first door body and the second door body to move relative to the housing to open the first air outlet and the second air outlet and close the third air outlet; or, when the operating mode is the internal circulation mode, controlling the driving component to drive the first door body and the second door body to move in the opposite direction relative to the housing to close the first air outlet and the second air outlet and open the third air outlet.

[0122] In this embodiment, according to the operating mode, the first door body and the second door body are controlled to move relative to the housing to open or close the first air outlet, the second air outlet and the third air outlet, meeting the requirements of different operating modes.

[0123] Specifically, when the fresh air mode is running, in order to realize the exchange and circulation of indoor air and outdoor air, the driving component is controlled to drive the first door body and the second door body to move relative to the housing to open the first air outlet and the second air outlet and close the third air outlet. At this time, the outdoor air inlet, the first air outlet and the indoor air inlet are connected, and the indoor air return port, the second air outlet and the outdoor air outlet are connected. Outdoor fresh air enters the room through the first air passage, and indoor dirty air is discharged outdoors through the second air passage, realizing fresh air replacement. When the internal circulation is running, in order to realize the circulation of indoor air, the driving component is controlled to drive the first door body and the second door body to move relative to the housing to close the first air outlet and the second air outlet and open the third air outlet. At this time, the indoor air return port, the third air outlet and the indoor air inlet are connected. Indoor air circulates indoors through the third air passage, realizing internal circulation.

[0124] Optionally, the step of determining the operating mode of the fresh air machine according to the indoor humidity includes: when RH < RH1, determining that the operating mode is the fresh air mode and the humidification mode; or, when RH1 < RH < RH2, determining that the operating mode is the fresh air mode; or, when RH2 < RH < RH3, determining that the operating mode is the fresh air mode and the dehumidification mode; or, when RH3 < RH, determining that the operating mode is the internal circulation mode and the dehumidification mode; where RH represents the indoor humidity, RH1 represents the first humidity threshold, RH2 represents the second humidity threshold, RH3 represents the third humidity threshold, and RH1 < RH2 < RH3.

[0125] In this embodiment, RH1, RH2, and RH3 are set, where RH1 < RH2 < RH3. When the indoor humidity is between RH1 and RH2, the human body feels relatively comfortable and no air humidity adjustment is required. The fresh air mode is executed to provide fresh air. By comparing the indoor humidity with the first humidity threshold, the second humidity threshold, and the third humidity threshold, the operation mode is determined according to the comparison result to improve the adaptability of the fresh air fan operation mode to the current air environment and improve the adjustment efficiency for the current air environment.

[0126] Specifically, when RH < RH1, it indicates that the current indoor air is relatively dry and the human body is prone to discomfort, such as dry mouth, dry throat, and sore throat. In this case, the humidification mode needs to be run to increase the indoor air humidity, and at the same time, the fresh air mode is run to provide fresh air for the indoor. When RH1 < RH < RH2, it indicates that the current indoor air is suitable and the human body feels comfortable, and no air humidity adjustment is required. The fresh air mode is run to provide fresh air for the indoor. When RH2 < RH < RH3, it indicates that the current indoor air is relatively humid. In this case, the dehumidification mode is run to reduce the indoor air humidity, and at the same time, the fresh air mode is run to provide fresh air for the indoor. When RH3 < RH, it indicates that the current indoor air is overly humid and the current indoor air needs to be quickly dehumidified. In this case, the dehumidification mode is run to reduce the indoor air humidity, and at the same time, the internal circulation mode is run to increase the indoor air circulation efficiency to accelerate the indoor air dehumidification efficiency.

[0127] In some embodiments, as shown in Fig.14 Another control method for a fresh air fan is provided, which is applied to the fresh air fan described in the above-mentioned some embodiments. The control method includes:

Through this control method of the fresh air fan, the intelligent degree of the fresh air fan is improved, thereby improving the practicability and reliability of the fresh air fan.

[0133] Exemplarily, the humidity sensor obtains the indoor humidity in real time and feeds back the current indoor humidity to the processor. The processor determines the operation mode adapted to the current air condition according to the indoor humidity. The processor regulates the electronic control component according to the determined operation mode to control the operation of the damper mechanism, the dehumidification mechanism and / or the humidification mechanism, realize the switching of the air path channel, and the switching of the working mode.

[0135] In this embodiment, the operation of the dehumidification mechanism and / or the humidification mechanism is controlled according to the operation mode to achieve switching between the dehumidification mode and the humidification mode, so as to improve the intelligence level of the fresh air fan.

[0136] In some embodiments, in combination Fig.15 As shown, another control method for a fresh air fan is provided, which is applied to the fresh air fan described in some of the above embodiments, and the control method includes:

[0137] S301, the processor obtains the current season;

[0141] S305: The processor controls the operation of the damper mechanism according to the operation mode.

[0142] By adopting the control method for the fresh air fan provided by the embodiment of the present disclosure, the operation mode can be determined according to the current season and indoor humidity. The air humidity that the human body feels comfortable is different in different seasons. For example, in summer, the humidity that the human body feels comfortable is 30% to 60%, and in winter, the humidity that the human body feels comfortable is 30% to 80%. According to the current season and indoor humidity, the operation mode that is compatible with the current air conditions is determined, and according to the operation mode, the operation of the damper mechanism, the dehumidification mechanism and / or the humidification mechanism is controlled to realize the switching of the air path channel and the switching of the working mode. The control method of the fresh air fan improves the intelligence level of the fresh air fan.

[0143] Exemplarily, the temperature sensor obtains the indoor temperature, the humidity sensor obtains the indoor humidity in real time, and feeds back the current indoor temperature and indoor humidity to the processor. The processor determines the current season according to the indoor temperature. The processor determines the operating mode adapted to the current air condition according to the current season and the indoor humidity. The processor regulates the electronic control component according to the determined operating mode to control the operation of the damper mechanism, the dehumidification mechanism and / or the humidification mechanism, realizes the switching of the air path channel, and the switching of the working mode.

[0144] Optionally, the current season is obtained through a network module of the fresh air fan.

[0145] In this embodiment, the fresh air fan is provided with a network module, which is used to connect to the user's home wireless network. The network module is connected to the Internet through a wireless network to obtain the current season. The processor then adjusts the current air environment according to the current season and indoor humidity, thereby improving the control accuracy of the fresh air fan for the current air environment and improving the intelligence of the fresh air fan.

[0146] Optionally, the current season is obtained through a device associated with the fresh air blower.

[0147] In this embodiment, the device associated with the fresh air fan can communicate with the fresh air fan via a wireless network or Bluetooth. Exemplarily, the device associated with the fresh air fan is one of a mobile phone, a television, or a computer. Taking a mobile phone as an example, the mobile phone connects to the fresh air fan via Bluetooth to achieve communication, or the mobile phone and the fresh air fan are connected to the same wireless network to achieve communication. The mobile phone has downloaded software compatible with the fresh air fan, and the software obtains the current season information in the mobile phone and sends the current season information to the fresh air fan via Bluetooth or a wireless network. The processor obtains the current season information and adjusts the current air environment according to the current season and indoor humidity, thereby improving the control accuracy of the fresh air fan for the current air environment.

[0148] It should be noted that as long as the device associated with the fresh air fan can communicate with the fresh air fan through a wireless network or Bluetooth to enable the fresh air fan to obtain the current season, no specific limitation is made here on the specific type of device.

[0149] In some embodiments, in combination Fig.16 As shown, another control method for a fresh air fan is provided, which is applied to the fresh air fan described in some of the above embodiments, and the control method includes:

[0150] S401, the processor obtains the current season;

[0151] S402, the processor determines a humidity threshold according to the current season;

[0152] S403, the processor obtains indoor humidity;

[0153] S404, the processor determines the operation mode of the fresh air fan according to the humidity threshold and the indoor humidity;

[0154] S405, the processor controls the dehumidification mechanism and / or the humidification mechanism to operate according to the operation mode;

[0155] S406: The processor controls the operation of the damper mechanism according to the operation mode.

[0156] In this embodiment, the air humidity that a human body feels comfortable with is different in different seasons. The current air humidity is different, corresponding to different fresh air fan operation modes. By setting different humidity thresholds according to different seasons, the adaptability of the fresh air fan operation mode to the current air environment is improved, thereby improving the intelligence of the fresh air fan.

[0157] Optionally, according to the current season, the step of determining the humidity threshold includes: when the current season is winter, the range of RH1 is 35% to 45%; or, when the current season is summer, the range of RH1 is 45% to 55%; or, when the current season is winter, the range of RH2 is 45% to 55%; or, when the current season is summer, the range of RH2 is 55% to 65%; or, when the current season is winter, the range of RH3 is 75% to 85%; or, when the current season is summer, the range of RH3 is 75% to 85%.

[0158] In this embodiment, RH1 represents the first humidity threshold, RH2 represents the second humidity threshold, and RH3 represents the third humidity threshold. Exemplarily, when the current season is winter, the specific value of RH1 is 40%. When the current season is summer, the specific value of RH1 is 50%. When the current season is winter, the specific value of RH2 is 50%. When the current season is summer, the specific value of RH2 is 60%. When the current season is winter, the specific value of RH3 is 80%. When the current season is summer, the specific value of RH3 is 80%. By setting different humidity thresholds according to different seasons, and comparing the indoor humidity with different humidity thresholds, determining the corresponding operation mode according to the comparison result, and controlling the dehumidification mechanism and / or humidification mechanism, as well as the operation of the damper mechanism, the integrated linkage of one or more functions of the fresh air fan, humidification and dehumidification is realized, so as to improve the adaptability of the operation mode of the fresh air fan to the current air environment and improve the regulation efficiency of the current air environment.

[0159] Exemplarily, in the case of summer, the fresh air machine is powered on and running. The processor obtains and determines that the current season is summer. The corresponding value of RH1 is 50%, the specific value of RH2 is 60%, and the specific value of RH3 is 80%. The humidity sensor obtains the current indoor humidity RH in real time and feeds back the indoor humidity RH to the processor. The indoor humidity RH is 55%. Since RH1 < RH < RH2, the processor determines that the operation mode is the fresh air mode. The processor regulates and controls the electronic control component according to the determined operation mode to control the driving component 40 to drive the first door body and the second door body to move relative to the housing, so as to open the first air outlet and the second air outlet and close the third air outlet 140. At the same time, control the first fan and the second fan to start to improve the fresh air replacement efficiency of the fresh air machine. At this time, the outdoor fresh air enters the first cavity through the outdoor air inlet and the first air outlet, then enters the fourth cavity, and then is sent into the room by the second fan through the indoor air inlet. At the same time, the first fan sucks the indoor dirty air from the indoor air return port into the third cavity, and the indoor dirty air then enters the second cavity and is discharged outdoors through the second air outlet and the outdoor air outlet to realize fresh air replacement.

[0160] Exemplarily, in the case of winter, the fresh air machine is powered on and running. The processor obtains and determines that the current season is winter. The corresponding value of RH1 is 40%, the specific value of RH2 is 50%, and the specific value of RH3 is 80%. The humidity sensor obtains the current indoor humidity RH in real time and feeds back the indoor humidity RH to the processor. The indoor humidity RH is 35%. Since RH < RH1, the processor determines that the operation mode is the fresh air mode and the humidification mode. The processor regulates and controls the electronic control component according to the determined operation mode to control the driving component to drive the first door body and the second door body to move relative to the housing, so as to open the first air outlet and the second air outlet and close the third air outlet, and control the humidifying mechanism to start. At the same time, control the first fan and the second fan to start to improve the fresh air replacement and humidification efficiency of the fresh air machine. At this time, the outdoor fresh air enters the first cavity through the outdoor air inlet and the first air outlet, flows through the humidifying mechanism located in the first cavity for humidification. The humidified air enters the fourth cavity and is sent into the room by the second fan through the indoor air inlet to realize fresh air humidification. At the same time, the first fan sucks the indoor dirty air from the indoor air return port into the third cavity, and the indoor dirty air then enters the second cavity and is discharged outdoors through the second air outlet and the outdoor air outlet to realize fresh air replacement. The humidity sensor obtains the current indoor humidity RH in real time and feeds back the indoor humidity RH to the processor. When RH reaches 40%, the processor switches the operation mode to the fresh air mode. The processor regulates and controls the electronic control component according to the switched operation mode to control the humidifying mechanism to close. At this time, the outdoor fresh air passes through the first air path channel and is sent into the room by the second fan. The indoor dirty air passes through the second air path channel and is discharged outdoors by the first fan, and switches to the fresh air mode.

[0161] For example, in winter, the fresh air fan is powered on. The processor obtains and determines that the current season is winter, and the corresponding RH1 value is 40%, the specific value of RH2 is 50%, and the specific value of RH3 is 80%. The humidity sensor obtains the current indoor humidity RH in real time and feeds the indoor humidity RH back to the processor. The indoor humidity RH is 85%. Since RH3 < RH, the processor determines that the operating mode is the internal circulation mode and the dehumidification mode. The processor controls the electronic control component according to the determined operating mode to control the drive component to drive the first door body and the second door body to move relative to the shell to close the first air outlet and the second air outlet, open the third air outlet, and control the humidification mechanism to close and the dehumidification mechanism to open. At the same time, the first fan and the second fan are controlled to turn on to improve the internal circulation and dehumidification efficiency of the fresh air fan. At this time, the first fan draws the indoor humid air from the indoor return air outlet into the third cavity and sends it into the second cavity. The indoor humid air enters the first cavity through the third air outlet. Indoor humid air enters the first cavity, flows through the dehumidification mechanism located in the first cavity for dehumidification, and the dehumidified air enters the fourth cavity, and is then sent into the room through the indoor air inlet by the second fan to achieve internal circulation dehumidification. The humidity sensor obtains the current indoor humidity RH in real time and feeds back the indoor humidity RH to the processor. When RH reaches 50%, the processor switches the operating mode to the fresh air mode. The processor regulates the electronic control component according to the switched operating mode to control the dehumidification mechanism to close. At the same time, the control drive component drives the first door body and the second door body to move relative to the shell to open the first air outlet and the second air outlet, and close the third air outlet. At this time, the outdoor fresh air passes through the first air path and is sent into the room by the second fan. The indoor polluted air passes through the second air path and is discharged to the outside by the first fan, switching to the fresh air mode.
