It should be noted that the filtering unit includes a device with a filtering function and related components. In the following embodiments, an embodiment in which a filter net is used as a filter unit will be described in detail.

Referring to fig. 1 to 4, an embodiment of the present application provides a control method of a refrigeration system. The refrigeration system comprises a refrigeration module 110 and a range hood 120, a hot exhaust pipeline of the refrigeration module 110 is connected with a main air duct of the range hood 120, and a filter screen is arranged on an air inlet of the refrigeration module 110. The control method of the refrigeration system comprises the following steps:

s110, acquiring an air inlet state of a filter screen;

s120, when the filter screen is determined to be blocked according to the air inlet state, executing any one of the following operations: the rotating speed of the main air duct fan is increased, and a filter unit blockage signal is generated.

Specifically, referring to fig. 2, the refrigeration system includes a refrigeration module 110 having a refrigeration function, and a hood 120 having a smoke exhaust function. The refrigeration module 110 may be integrated with the range hood 120 to form a refrigeration integrated range (as shown in fig. 3), or the refrigeration module 110 and the range hood 120 are two independent devices, which is not specifically limited in the embodiment of the present application. However, it should be understood that, no matter the refrigeration module 110 and the range hood 120 are integrally disposed, or the refrigeration module 110 and the range hood 120 are separately disposed, the hot air exhaust duct of the refrigeration module 110 and the main air duct of the range hood 120 are in a connectable state, that is, the hot air exhausted by the refrigeration module 110 when the refrigeration function is turned on can flow to the main air duct of the range hood 120 through the hot air exhaust duct. It can be understood that the refrigerant in the refrigeration module 110 in the embodiment of the present application is an inert refrigerant, so as to avoid a danger when the refrigeration module 110 operates.

Referring to fig. 3, the refrigeration module 110 and the range hood 120 are integrated into a refrigeration integrated range as an example. The integrated kitchen of refrigeration is closed design, and refrigeration module 110 sets up in the inside of the integrated kitchen of refrigeration. When the fan of the evaporator of the refrigeration module 110 rotates, the evaporator absorbs hot air inside the kitchen from the air inlet 111 arranged at the skirting line position of the refrigeration integrated stove, and the hot air passes through the evaporator and the condenser and then is changed into cold air and is exhausted from the cold air exhaust port 112. Wherein, the hot air formed when the condenser dissipates heat and liquefies flows to the main air duct of the hood 120 from the hot exhaust duct. It is understood that the specific locations of the intake vent 111 and the cold exhaust vent 112 can be adjusted according to the actual requirements.

When the refrigeration module 110 operates in the refrigeration mode, the air intake state of the filter screen is obtained, wherein the air intake state is used for representing the air intake at the air inlet 111 of the refrigeration module 110, that is, when the air intake state is abnormal, it indicates that the air intake at the air inlet 111 is small, and at this time, the filter screen may be seriously blocked or partially blocked. When the filter screen at the air inlet 111 of the refrigeration module 110 is determined to be blocked according to the air inlet state, any one of the operations of increasing the rotating speed of the main air duct fan and generating a blocking signal of the filter unit is executed, so that the main air duct fan is utilized to accelerate the discharge of hot air in the refrigeration module 110, namely, the flow rate of air in the refrigeration module 110 is increased; or the user is reminded to replace the filter screen or clean the filter screen through the blocking signals of the filter units in the forms of sound, light and the like, so that the influence of the blocking of the filter screen on the air conditioner or other devices is avoided to a certain extent.

In some embodiments, the step S110 includes the following two embodiments according to different structural features of the refrigeration module:

firstly, the refrigeration module comprises a condenser and an evaporator, wherein an electric signal detection device is respectively arranged on a motor corresponding to a fan of the condenser and a motor corresponding to a fan of the evaporator; or when the evaporator fan and the condenser fan share the motor, the shared motor is provided with an electric signal detection device. The electric signal detection device is used for detecting electric signals corresponding to the fan control equipment, for example: for detecting an electrical signal of a motor for controlling a rotational speed, a rotational direction, etc. of the fan. The electrical signal includes a current signal, a voltage signal, a power signal, and the like.

In some embodiments, step S110 further comprises the sub-steps of: and when the first electric signal Ia is smaller than the first threshold value and the second electric signal Ib is smaller than the second threshold value, determining that the air inlet state is abnormal.

Step S120 includes the sub-steps of: and when the air inlet state is abnormal, determining that the blockage state is blocked, generating a filter unit blockage signal, and controlling the compressor, the evaporator fan and the condenser fan to stop running.

Specifically, referring to fig. 5, the first threshold represents an upper limit value of an electric signal when a motor corresponding to an evaporator fan rotates, for example: the first threshold value represents the upper limit value of the current signal when the motor rotates, the first electric signal Ia represents the current signal at the moment, and the first threshold value can be selected from any value within 0-10A. The second threshold represents an upper limit value of an electric signal when a motor corresponding to the condenser fan rotates, for example: the second threshold value represents the upper limit value of the current signal when the motor rotates, the second electric signal Ib represents the current signal at the moment, and the second threshold value can be any value within 0-10A. And acquiring a first electric signal Ia of the evaporator fan and a second electric signal Ib of the condenser fan according to a preset time interval. When the filter screen of the air inlet is blocked seriously, the air inlet volume of the refrigeration module is smaller, the evaporator fan and the condenser fan are both in an idle state at the moment, and the motor current in the idle state is smaller. Based on this, when the first electrical signal Ia and the second electrical signal Ib are judged to be smaller than the corresponding upper limit values, it is indicated that the air inlet state of the refrigeration module is abnormal, and therefore the filter screen arranged at the air inlet is determined to be seriously blocked according to the air inlet state. At this time, if the refrigeration module is controlled to execute operation, the temperature of the refrigeration module will be raised, and the compressor is started and stopped for protection. Therefore, when the filter screen of the air inlet is judged to be in a serious blockage state according to the mode, the compressor of the refrigeration module, the motor corresponding to the evaporator fan and the motor corresponding to the condenser fan are controlled to stop running, and filtering unit blockage signals in the forms of sound, light and the like are generated. For example, the refrigeration module further comprises a display module, the display module is used for sending the filtering unit blockage signal to the display module, and the display module displays according to the filtering unit blockage signal; or the refrigeration module further comprises a wireless communication module, and the wireless communication module sends the filtering unit blockage signal to the terminal equipment in a wireless communication mode so as to remind a user to replace the filter screen or clean the filter screen. It is understood that the specific value of the first threshold may be adaptively selected according to actual situations, and the embodiment of the present application is not particularly limited.

In addition, when the first electric signal Ia is greater than the first threshold value and the second electric signal Ib is greater than the second threshold value, it indicates that the intake air amount of the intake vent is normal, i.e. the intake vent has no blockage or a slight blockage. At this time, the refrigeration module keeps operating normally.

In other embodiments, step S110 further comprises the sub-steps of: when the first electric signal Ia is larger than the first threshold value and the second electric signal Ib is smaller than the second threshold value, determining that the air inlet state is abnormal; or when the first electric signal Ia is smaller than the first threshold value and the second electric signal Ib is larger than the second threshold value, determining that the air inlet state is abnormal.

Step S120 includes the sub-steps of: and when the air inlet state is abnormal, determining that the blockage state is blocked, and increasing the rotating speed of the fan of the main air duct.

Specifically, referring to fig. 5, the first threshold represents an upper limit value of an electric signal when a motor corresponding to an evaporator fan rotates, for example: the first threshold value represents the upper limit value of the current signal when the motor rotates, the first electric signal Ia represents the current signal at the moment, and the first threshold value can be selected from any value within 0-10A. The second threshold represents an upper limit value of an electric signal when a motor corresponding to the condenser fan rotates, for example: the second threshold value represents the upper limit value of the current signal when the motor rotates, the second electric signal Ib represents the current signal at the moment, and the second threshold value can be any value within 0-10A. And when at least one of the first electric signal Ia and the second electric signal Ib is smaller than the corresponding upper limit value, indicating that at least one of the motor of the evaporator fan and the motor of the condenser fan is in an overload running state. The state may be caused by the unsmooth air exhaust of the hot air exhaust duct of the refrigeration module or the unsmooth air exhaust of the cold air exhaust duct of the refrigeration module, and therefore, when the air intake state is determined to be abnormal according to the state, it is determined that the filter screen arranged at the air inlet is partially blocked. At the moment, the motor corresponding to the fan of the main air duct is controlled to increase the speed so as to accelerate the discharge of hot air in the hot exhaust pipeline of the refrigeration module, thereby improving the circulation speed of air in the refrigeration module and avoiding the influence on the refrigeration module when the filter screen is blocked to a certain extent. It is understood that the specific value of the second threshold may be adaptively selected according to actual situations, and the embodiment of the present application is not particularly limited.

In addition, a swinging blade can be arranged at a cold air exhaust port of the refrigeration module, wherein the cold air exhaust port is connected with a cold air exhaust pipeline of the refrigeration module. When the blockage state of the filter screen of the air inlet is determined to be blocked according to the conditions described in the above embodiments, the swinging blade is controlled to swing so as to prevent the cold air outlet from being blocked.

In some embodiments, when the evaporator fan and the condenser fan share a motor, the common electrical signal of the shared motor can be determined by dividing the common electrical signal into the following three conditions:

taking the common electric signal as the common current signal as an example, when the common current signal is smaller than the common current lower limit value, it indicates that the evaporator fan and the condenser fan are in an idle state, and at the moment, the air inlet volume of the air inlet is smaller, so that it is determined that the filter screen of the air inlet is seriously blocked. And controlling a compressor of the refrigeration module, a motor corresponding to an evaporator fan and a motor corresponding to a condenser fan to stop running, and generating filtering unit blockage signals in the forms of sound, light and the like.

When the common current signal is larger than the upper limit value of the common current, the air inlet volume of the air inlet is normal, namely the filter screen of the air inlet is not blocked or the blocking condition is slight. At this time, the refrigeration module remains operating normally.

And when the common current signal is greater than the lower limit value of the common current and is less than the upper limit value of the common current, indicating that at least one of the motor of the evaporator fan and the motor of the condenser fan is in an overload running state. The state may be caused by the unsmooth air exhaust of the hot air exhaust pipeline of the refrigeration module or the unsmooth air exhaust of the cold air exhaust pipeline of the refrigeration module, so that the rotating speed of the main air duct fan corresponding to the motor is increased to accelerate the discharge of hot air in the hot air exhaust pipeline of the refrigeration module, and further improve the circulation speed of air in the refrigeration module.

And in the second mode, an air speed detection device is arranged at the air inlet of the refrigeration module. The wind speed detection device is used for detecting the wind speed of the inlet wind passing through the filter screen of the air inlet of the refrigeration module.

In some embodiments, step S110 further comprises the sub-steps of: and when the air inlet speed is less than a third threshold value, determining that the air inlet state is abnormal.

Step S120 includes the substeps of: and when the air inlet state is abnormal, determining that the blockage state is blocked, generating a filter unit blockage signal, and controlling the compressor, the evaporator fan and the condenser fan to stop running.

Specifically, with reference to fig. 6, the third threshold represents a lower limit value of the wind speed at the air intake of the refrigeration module, for example: the third threshold value can be any value of 0-10 m/s. When the air inlet speed F detected by the air speed detection device is smaller than a third threshold value, the air speed of the air inlet is low, namely the air inlet volume of the air inlet is small, and the filter screen of the air inlet is seriously blocked. At the moment, the blockage state of the filter screen of the air inlet of the refrigeration module is determined to be blocked, the motors corresponding to the compressor and the evaporator fan and the motors corresponding to the condenser fan are controlled to stop running, and filtering unit blockage signals in the forms of sound, light and the like are generated. For example, the refrigeration module further comprises a display module, the display module sends the filtering unit blockage signal to the display module, and the display module displays according to the filtering unit blockage signal; or the refrigeration module further comprises a wireless communication module, and the wireless communication module sends the filtering unit blockage signal to the terminal equipment in a wireless communication mode so as to remind a user of replacing the filter screen. It is understood that the specific value of the third threshold may be adaptively selected according to actual situations, and the embodiment of the present application is not particularly limited.

Referring to fig. 6, in other embodiments, step S110 further includes the sub-steps of: and when the air inlet speed F is greater than the third threshold value and less than the fourth threshold value, determining that the air inlet state is abnormal.

Step S120 includes the substeps of: and when the air inlet state is abnormal, determining that the blockage state is blocked, and increasing the rotating speed of the main air duct fan.

Specifically, the fourth threshold represents an upper limit value of the air speed at the air inlet of the refrigeration module, and when the air speed F of the intake air detected by the air speed detection device is greater than the third threshold and smaller than the fourth threshold, it indicates that the air speed at the air inlet is low, that is, the intake air amount at the air inlet is small, and a part of the filter screen at the air inlet is blocked. At the moment, the blockage state of the filter screen of the air inlet of the refrigeration module is determined to be blockage, the rotating speed of the main air duct fan corresponding to the motor is increased, and the hot air in the hot exhaust pipeline of the refrigeration module is exhausted in an accelerated manner so as to keep the heat exchange efficiency of the refrigeration module. It is understood that the specific value of the fourth threshold may be adaptively selected according to actual situations, and the embodiment of the present application is not particularly limited.

In addition, when the air inlet speed F is larger than the fourth threshold value, the air inlet volume of the air inlet is normal, namely, the filter screen of the air inlet is not blocked or the blocking condition is slight. At this time, the refrigeration module remains operating normally. Wherein the third threshold is less than the fourth threshold.

It can be understood that according to actual needs, the electric signal detection and the wind speed detection can be combined to improve the accuracy of the air inlet state judgment.

Referring to fig. 7, in some embodiments, after step S120 described in any of the above embodiments, the method for controlling a refrigeration system further includes the steps of:

s610, acquiring a function starting state of the refrigeration module;

s620, when the function opening state is open, executing the following steps again: acquiring an air inlet state of the filter unit;

and S630, when the function opening state is closed, controlling the refrigeration module to stop running.

Specifically, after step S120 described in any of the above embodiments is executed, if a cooling function closing signal is obtained, the cooling function of the cooling module is closed, at this time, the function opening state is closed, and the operating state of the range hood is running or stopped. If the refrigeration function closing signal is not obtained, the step S110 is executed again to judge whether the filter screen is blocked according to the air inlet state of the filter screen at the air inlet, and any operation of increasing the rotating speed of the main fan and generating a blocking signal of the filter unit is executed when the filter screen is blocked.

The control method of the refrigeration system provided by the embodiment of the application judges the state of the air inlet through at least one of the air inlet speed detected by the air speed detection device, the first electric signal of the evaporator fan and the second electric signal of the condenser fan, namely, judges the air inlet amount of the filter screen of the air inlet. When the air inlet state is abnormal, the air inlet amount of the air inlet filter screen is small, and the condition that the air inlet filter screen is seriously blocked or partially blocked is determined. According to the difference of jam condition, carry out at least one of increase main fan rotational speed, formation filter unit jam signal to avoid the filter screen to block up the influence that causes the refrigeration module to a certain extent. When the air inlet state is normal, the situation that the filter screen of the air inlet is not blocked is determined, and the refrigeration module is controlled to keep normal operation at the moment.

Referring to fig. 8, an embodiment of the present application further provides a controller, where the controller is applied to a refrigeration system, the refrigeration system includes a refrigeration module and a range hood, and a hot exhaust duct of the refrigeration module is connected to a main air duct of the range hood. And a filtering unit is arranged on the air inlet of the refrigeration module. The controller includes:
