It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

It should be noted that, in the following embodiments, the compressor of the refrigeration module is a fixed-frequency compressor, that is, the refrigeration temperature cannot be adjusted. However, it should be understood that, by making adaptive modifications to the embodiments of the present application, the hot exhaust control method provided by the embodiments of the present application can also be applied to an inverter compressor, and therefore, the solution applied to the inverter compressor should also belong to the protection scope of the embodiments of the present application.

In addition, it should be noted that the target object is a user or other obstacle, and in the following embodiments, the target object is specifically described as an example of the user.

Referring to fig. 1 to 3, an embodiment of the present application provides a method for controlling hot exhaust air, which is applied to a refrigeration system. The refrigeration system comprises a refrigeration module 110 and a range hood 120, and a hot exhaust duct of the refrigeration module 110 is connected with a main air duct of the range hood 120. The refrigeration module 110 includes a bypass pipe, one end of which is used to connect with the hot exhaust pipe, the other end of which is used to connect with the cold exhaust pipe of the refrigeration module 110, and the cold exhaust pipe is used to connect with the cold exhaust port of the refrigeration module 110.

The hot air discharge control method comprises the following steps:

s110, acquiring a first distance parameter between the cold exhaust port and a user, and acquiring a second distance parameter between the cold exhaust port and the user at intervals of first preset time;

s120, when the difference value of the first distance parameter and the second distance parameter is smaller than a first preset distance threshold value, acquiring a third distance parameter between the cold air exhaust opening and a user at intervals of second preset time;

and S130, controlling the conduction state of the bypass pipeline according to the third distance parameter, and controlling the hot air in the hot exhaust pipeline to flow to at least one of the cold exhaust pipeline and the main air duct.

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.

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 a position of a skirting line of the refrigeration integrated stove, and the hot air is changed into cold air after passing through the evaporator and the condenser and is discharged from the cold air outlet 111. Wherein, the hot wind formed when the condenser dissipates heat and liquefies flows to the main wind channel of the range hood 120 from the hot exhaust duct.

Referring to fig. 4, the bypass duct is a pipe disposed between the hot exhaust duct and the cold exhaust duct, or a check valve disposed between the hot exhaust duct and the cold exhaust duct. When the bypass pipeline is a pipeline, a valve control switch can be arranged at any position on the bypass pipeline so as to realize the unidirectional conduction control of the bypass pipeline. When the bypass pipeline is the check valve, the two ends of the check valve can be connected with the hot exhaust pipeline and the cold exhaust pipeline respectively, so that part of hot air in the hot exhaust pipeline can be exhausted to the cold exhaust pipeline from the bypass pipeline, the hot air exhaust amount of the main air channel is reduced, and the smoking exhaust amount in the main air channel is improved.

In response to a function opening instruction of the refrigeration module, the refrigeration system acquires a first distance parameter between a user and the cold exhaust port in the modes of an infrared detector and the like. After a certain time interval (a first preset time, for example, any value between 0 and 600 s), the second distance parameter between the user and the cold exhaust outlet is obtained again, so as to determine whether the change value of the distance between the user and the cold exhaust outlet is smaller than the first preset distance threshold value after the first preset time interval according to the first distance parameter and the second distance parameter. When the variation value is smaller than the first preset distance threshold value, the variation value indicates that the position of the user after the interval of the first preset time is less. At this time, the third distance parameter between the user and the cold exhaust opening is obtained again, and the bypass pipeline is controlled to be switched on or switched off according to the third distance parameter, for example: controlling hot air in the hot air exhaust pipeline to be exhausted to the main air duct; or one part of hot air is discharged to the main air duct, and the other part of hot air is discharged to the cold air discharge pipeline, so that the ratio of the hot air discharge amount to the smoking discharge amount in the main air duct is adjusted on the premise of ensuring the refrigeration effect on a user. It can be understood that the amount of hot air discharged into the cold exhaust duct can be adaptively set according to actual needs, for example: the opening degree of the check valve is adjusted according to actual needs, and the embodiment of the present application is not particularly limited. In addition, the control method for hot air discharge described in the embodiments of the present application and the following embodiments may be applied to other scenes according to actual needs, besides the kitchen.

According to the hot air discharge control method provided by the embodiment of the application, the position change between the user and the cold air exhaust opening after the first preset time interval is judged through the difference value between the first distance parameter and the second distance parameter. When the position changes less, acquire the third distance parameter to switch on or close according to third distance control bypass pipeline, thereby control hot-blast flow direction in the hot exhaust pipeline to main wind channel, cold exhaust pipeline in at least one, and then realize adjusting the hot-blast emission in the main wind channel under the prerequisite of guaranteeing the refrigeration effect, in order to avoid to a certain extent heating the influence of module to smoke ventilator smoking effect.

Hereinafter, the step S130 will be specifically described with reference to the features of the refrigeration module described in the above embodiment.

Referring to fig. 5, in some embodiments, step S130 includes the sub-steps of:

and when the third distance parameter S3 is smaller than or equal to a second preset distance threshold value L2, controlling the conduction of the bypass pipeline, and controlling the hot air in the hot exhaust pipeline to flow to the cold exhaust pipeline and the main air duct.

The hot air discharge control method further includes: at least one of a fan controlling the evaporator and a fan controlling the condenser is operated at a first speed.

Specifically, when the position change of the user after the interval of the first preset time is small, the third distance parameter S3 between the user and the cold exhaust port is acquired again at an interval of the second preset time (for example, any value between 0 and 600S). Comparing the third distance parameter S3 with a second preset distance threshold L2, wherein, the second preset distance threshold L2 represents a minimum distance defining value between the user and the cold exhaust, for example: the second preset distance threshold L2 is any value within 0 to 10 m. And when the third distance parameter S3 is smaller than the second preset distance threshold value L2, indicating that the distance between the user and the cold air exhaust opening is shorter. At the moment, at least one of the fan of the evaporator and the fan of the condenser is controlled to run at a low speed (first speed), and the bypass pipeline is controlled to be communicated, so that part of hot air in the hot exhaust pipeline is exhausted to the cold exhaust pipeline, and part of hot air is exhausted to the main air duct of the range hood, the hot air exhaust amount in the main air duct is reduced, the smoking exhaust amount in the main air duct is improved, and the influence of the refrigeration module on the smoking effect of the range hood is further avoided to a certain extent. And cold air in the cold air exhaust pipeline and hot air exhausted by the bypass pipeline are mixed and then exhausted to the cold air exhaust port, so that the temperature of the cold air exhaust port is increased. However, since the distance between the user and the cold exhaust port is short, that is, the cooling temperature sensed by the user is low, a more comfortable cooling environment can be provided for the user by properly increasing the temperature of the cold exhaust port. It can be understood that the specific value of the first speed may be adaptively selected according to actual needs, and the embodiment of the present application is not particularly limited.

Referring to fig. 5, in some embodiments, step S130 includes the sub-steps of:

when the third distance parameter S3 is greater than the second preset distance threshold L2 and less than the third preset distance threshold L3, controlling at least one of the blower of the evaporator and the blower of the condenser to operate at the second speed, and obtaining a speed parameter V1 of the blower of the main air duct;

and when the speed parameter V1 is greater than a preset speed threshold value V0, controlling the conduction of the bypass pipeline and controlling the hot air in the hot exhaust pipeline to flow to the cold exhaust pipeline and the main air duct.

Specifically, when the position change of the user after the interval of the first preset time is small, the third distance parameter S3 between the user and the cold exhaust port is acquired again at an interval of the second preset time (for example, any value between 0 and 600S). Wherein the second preset distance threshold L2 represents a minimum distance defining value between the user and the cold exhaust outlet, for example: the second preset distance threshold value L2 is any value within 0-10 m; the third preset distance threshold L3 represents a maximum distance defining value between the user and the cold exhaust, for example: the third preset distance threshold L3 is any value within 0 to 20 m. The second preset distance threshold value L2 and the third preset distance threshold value L3 form a preset distance range (larger than the second preset distance threshold value L2 and smaller than the third preset distance threshold value L3), the third distance parameter S3 is compared with the preset distance range, when the third distance parameter S3 is within the preset distance range, it is indicated that the distance between the user and the cold exhaust port is moderate, and the user can still feel a good refrigeration effect at the moment. And controlling at least one of the fan of the evaporator and the fan of the condenser to operate at a medium speed (second speed), and acquiring a speed parameter V1 of the main fan. And comparing the speed parameter V1 of the main fan with a preset speed threshold value V0, and when the speed parameter V1 of the main fan is greater than the preset speed threshold value V0, indicating that the main air duct fan is in a high-speed running state. At the moment, the bypass pipeline is controlled to be communicated, so that part of hot air in the hot exhaust pipeline is exhausted to the cold exhaust pipeline, and part of hot air is exhausted to the main air duct of the range hood, namely, on the premise that a user can feel a good refrigeration effect, hot air in the part of hot exhaust pipeline is exhausted to the cold exhaust pipeline through the bypass pipeline, and the hot air exhaust amount in the main air duct is reduced. Meanwhile, the hot air discharge of the refrigeration module is improved by using the main air duct fan. It can be understood that specific values of the second preset time, the second preset distance threshold L2, and the third preset distance threshold L3 may be adaptively selected according to actual needs, and the embodiment of the present application is not particularly limited.

Further, when the speed parameter V1 of the main air blower is less than or equal to the preset speed threshold V0, it indicates that the speed of the main air duct blower is low, or the gear of the main air duct blower is not the highest gear. At the moment, the running speed of the fan of the main air duct is increased, and the bypass pipeline is controlled to be conducted, so that on the premise that a user can feel a good refrigeration effect, hot air in a part of hot air exhaust pipelines is exhausted to the cold air exhaust pipeline through the bypass pipeline, and therefore the hot air exhaust amount in the main air duct is reduced. Meanwhile, the hot air discharge of the refrigeration module is improved by using the main air duct fan.

Referring to fig. 5, in some embodiments, step S130 includes the sub-steps of:

and when the third distance parameter S3 is greater than or equal to a third preset distance threshold value L3, closing the bypass pipeline and controlling hot air in the hot exhaust pipeline to flow to the main air duct.

The hot blast emission control method further includes: and controlling at least one of the fan of the evaporator, the fan of the condenser and the fan of the main air duct to operate at a third speed.

In particular, the third preset distance threshold L3 represents a maximum distance defining value between the user and the cold exhaust, for example: the third preset distance threshold L3 is any value within 0 to 20 m. When the distance (the third distance parameter S3) between the user and the cold air outlet is greater than or equal to the preset distance threshold, it indicates that the distance between the user and the cold air outlet is relatively long, and at this time, if the temperature of the cold air outlet is increased, the refrigeration effect on the user will be affected. Therefore, the bypass pipeline is controlled to be closed, namely, all hot air in the hot exhaust pipeline is controlled to be exhausted to the main air duct of the range hood, and at least one of the fan of the evaporator, the fan of the condenser and the fan of the main air duct is controlled to operate at a high speed (third speed), so that the hot air exhaust of the refrigeration module is accelerated by using the fan of the main air duct on the premise of not adjusting the temperature of the cold air outlet.

Referring to fig. 6, in some embodiments, after step S130 described in any of the above embodiments, the hot blast discharging control method 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 a first distance parameter between a cold exhaust port and a user, and acquiring a second distance parameter between the cold exhaust port and the user at intervals of first preset time;

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

Specifically, after step S130 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 acquired, the step S110 is executed again to circularly adjust the refrigeration effect of the refrigeration module and the hot air discharge amount of the main air duct according to the first distance parameter, the second distance parameter and the third distance parameter, so that the influence of the refrigeration module on the smoke suction effect of the range hood is avoided to a certain extent.

According to the hot air discharge control method, the position change of the user after the first preset time interval is judged through the first distance parameter and the second distance parameter, and when the position change of the user after the first preset time interval is small, the third distance parameter between the user and the cold air exhaust opening is obtained. According to the comparison result of the third distance parameter, the second preset distance threshold and the third preset distance threshold, at least one of the conduction states of the fan of the evaporator, the fan of the condenser, the fan of the main air duct and the bypass pipeline is adjusted, so that on the premise of ensuring the refrigeration effect of a user, the discharge amount of hot air in the main air duct is reduced, the discharge amount of oil smoke in the main air duct is improved, and the influence of the refrigeration module on the smoke absorption effect of the range hood is further avoided to a certain extent.

Referring to fig. 7, the embodiment of the present application further provides a controller applied to a refrigeration system. The refrigerating system comprises a refrigerating module and a smoke exhaust ventilator, wherein a hot exhaust pipeline of the refrigerating module is connected with a main air duct of the smoke exhaust ventilator. Wherein, the refrigeration module includes the by-pass line, and the one end of by-pass line is used for being connected with hot exhaust duct, and the other end of by-pass line is used for being connected with the cold exhaust duct of refrigeration module, and cold exhaust duct is used for being connected with the cold exhaust opening of refrigeration module.
